| PURPOSE:To detect a digital data signal and a synchronizing signal accurately by automatically varying a reference level so that the synchronizing signal has a normal high or low level period. CONSTITUTION:While an EFM signal is inputted, a reference level signal is inputted to a comparator 1 to decides on a high level or low level period of an EFM signal (a) for a reference level (f). An EFM digital signal (b) is inputted to a deciding circuit 6 to decide on whether a synchronizing signal has a prescribed 11-channel bit in a low level period or not. For example, when the reference level (f) is lower than an adequate level, the 11-channel low-level period of the synchronizing signal is shorter than the normal 11-channel bit, so a counter 4 goes up to increase the output of a D/A converter 5. Namely, the reference level (f) rises to approximate to the adequate level. Thus, the digital signal and synchronizing signal are detected accurately. | ||||||
| 143 | Power handle device with narrow section used for line trimmer* etc* | JP8526980 | 1980-06-25 | JPS569182A | 1981-01-30 | ROIDO EICHI TATSUGURU JIYUNIA |
| A narrow profile power handle uniquely adapted for use as a flexible line trimmer having improved handling and safety features is disclosed. The power handle is also equipped with a quick connect and disconnect coupling and is useful for driving attachments to produce hand held rotary implements and tools such as brush cutters, edgers, cultivators, drills, etc., hand held reciprocating implements and tools such as hedge clippers, saws, etc., as well as portable water pumps, air compressors, generators, etc. The crankshaft of a two-stroke internal combustion engine is disposed along the longitudinal axis of a narrow profile housing which includes a rear handle having a hand grip portion disposed above and projecting rearwardly parallel to the axis of the housing. The cylinder extends upwardly from the crankcase, the carburetor is disposed below the crankcase, the flywheel, ignition system and starter to the rear, and the gas tank is disposed below the rear handle. The muffler is disposed along the forward face of the housing for discharging products of combustion forwardly of the housing and away from the operator, thereby permitting the assembly to be rotated for various trimming operations without exposing the operator to the risk of burn injury. A recoil starter handle, a choke control, throttle control and ignition kill switch are conveniently clustered around and near the hand grip portion of the rear handle which allows the operator to observe and exercise positive control over both the power handle and the cutter head while starting and operating the engine. The power handle includes a quick disconnect coupling for attaching the portable power unit to drive various attachments. As a result of this arrangement, the power handle is generally symmetrical about the longitudinal vertical plane and is of minimum width. The drive shaft of the line trimmer assembly is aligned with the crankshaft of the engine and a forward handle is disposed above the drive shaft ahead of the engine housing. As a result, the center of gravity of the overall line trimmer assembly is below and between the forward and rearward handles, thereby providing improved balance and maneuverability. | ||||||

| An equipment stabilizer for a pull cord start that secures a piece of equipment, such as a chain saw, to a base plate via lockable jig clamps and assists in pulling the pull cord start by providing a pulley operated by a foot pedal. Ratchet straps pass through a horizontal slot through the base plate. An upright beam on the base plate front side has vertically aligned apertures proximal an upper side thereof for spring tension adjustment. A pulley operationally connects a pedal member of the foot pedal to a handle of the pull cord start. Pressing on the pedal member while holding onto the vertical beam moves the pull cord start handle toward the wheel end to start a motor of the piece of equipment. | ||||||

An operating-mode selector having an off position, an operating position and a starting position is provided. The selector, trigger lock and the trigger are pivotally mounted. A first latching element is provided on the selector and a second latching element is provided on the trigger element, which coact in the starting position of the selector and the starting position of the trigger and hold the trigger in its starting position. To ensure that the starting position of the selector can only be engaged when the trigger is actuated, the second latching element lies outside of the pivot path of the first latching element in the non-actuated position of the trigger. | ||||||
