摘要： In an internal-combustion piston driving apparatus comprising a housing, a cylinder cover fixed to the housing, a cylinder slidably provided to the housing, a piston reciprocally slidably provided in the cylinder, a combustion chamber defined by the housing, the cylinder, and the piston, a fuel supplying device for supplying fuel to the combustion chamber, and an ignition control device for producing a high voltage to ignite the fuel supplied to the combustion chamber, piston position detector for detecting a position of the piston is provided at the wall of the cylinder between top dead point and bottom dead point of the piston. Besides, a decompression channel is provided so as to connect the combustion chamber placed upper than the top dead point with atmosphere for exhausting a combusted gas in the combustion chamber when the piston passes the piston position detector. The decompression channel is opened and closed by means of slide of the cylinder. In addition, a suction valve is provided to the cylinder cover to be placed lower than bottom dead point of the piston whereby the piston is returned by means of atmospheric pressure after a power stroke of said piston.

摘要： A tightening apparatus includes a drive motor and a bit are coupled to each other by engagement of a clutch mechanism, the engagement thereof being maintained by a force of a spring one end of which is coupled to the clutch mechanism and the drive motor is released from engagement with the bit when the tightening torque of the bit exceeds a value corresponding to the force of the spring. The tightening apparatus comprises a cylinder and a plunger encased in the cylinder for holding the other end of the spring. The plunger is movable by a drive mechanism such that the force of the spring is varied, whereby the tightening force to be applied to the bit is adjustable in accordance with the position of the plunger as adjusted by the drive mechanism.

摘要： A portable power tool such as a portable circular saw is provided with a sawdust collection system based on the generation of an air flow resulting from rotation of a rotary cutting blade, with this air flow being guided to transport sawdust resulting from cutting operations along a guide path through a first discharge aperture into a dust box in which the sawdust is precipitated, with a low-velocity air flow then passing out of the dust box through a second discharge aperture to be recirculated through the flow path. Extremely effective dust collection is attained with a simple configuration, while the dust box can be positioned such that the weight of accumulated sawdust therein does not significantly affect the balance or ease of operation of the portable power tool.

摘要： A portable motor-driven cutter for cutting off a sheet material includes an eccentric shaft rotatably supported by a gear case and a gear cover, an L-shaped driver arm having an upper end rotatably fitted over an eccentric portion of the eccentric shaft, a cutting blade detachably mounted on the lower end of the driver arm, and a scribing blade detachably mounted on a base on which the gear case is mounted. When the eccentric shaft is rotated by a motor, the cutting blade is moved in an eccentric pattern to cut off a sheet material along a straight line scribed by the scribing blade. The cutting blade and the scribing blade are produced from a single break-off disposable cutter blade.

摘要： An ink jet printer has a plurality of piezoelectric elements arranged in a matrix form in which each piezoelectric element is connected between one of TS lines and one of selection lines. The TS lines are connected, one by one and in a time sharing manner, to a voltage source E.sub.1 so as to be enabled. The remaining TS lines are connected to a voltage source E.sub.2 so as to be disabled. The selection lines are selectively connected to a voltage source E.sub.3 so as to be enabled. Non-selected selection lines are connected to a voltage source E.sub.4 so as to be disabled. A selected piezoelectric element connected between enabled TS line and enabled selection line is applied with a driving voltage. A non-selected piezoelectric element connected between enabled TS line and disabled selection line, or between disabled TS line and enabled selection line, or between disabled TS line and disabled selection line, is applied with a non-driving voltage. The voltages supplied from the respective voltage sources are selected so that the non-driving voltage is one third or minus one third of the driving voltage. With the thus determined non-driving voltage, no ink droplet is ejected from a nozzle corresponding to the non-selected piezoelectric element while ensuring a sufficient amount of ink to be ejected from a nozzle corresponding to the selected piezoelectric element.
摘要翻译：喷墨打印机具有以矩阵形式布置的多个压电元件，其中每个压电元件连接在TS线之一和选择线中的一个之间。 TS线一个接一个地以时间共享的方式连接到电压源E1，以使其能够被使能。剩余的TS线连接到电压源E2以被禁用。选择线选择性地连接到电压源E3以使能。未选择的选择线连接到电压源E4以被禁用。连接在使能的TS线路和使能选择线路之间的选择的压电元件被施加驱动电压。连接在使能的TS线路和禁用的选择线路之间，或者在禁用的TS线路和使能的选择线路之间或者在禁用的TS线路和禁用的选择线路之间连接的未选择的压电元件被施加非驱动电压。选择从各个电压源提供的电压，使得非驱动电压是驱动电压的三分之一或者三分之一。利用如此确定的非驱动电压，在确保从对应于所选择的压电元件的喷嘴喷射足够量的墨水的同时，不会从与未选择的压电元件相对应的喷嘴喷射墨滴。
