Abstract: PROBLEM TO BE SOLVED: To provide a closing valve capable of stabilizing an operational response. SOLUTION: This closing valve is provided with a water inflow port 21 and a water outflow port 23 in a housing 2. The valve also has a piston 3 axially slidable within the housing 2 with an external operation of a shaft 6, and a pressure counteracting means for cancelling out a pressure received by the piston 3 from water in the water outflow port 23 in the other direction. The piston 3 slides in one axial direction to seat on a seat surface 2a of the housing 2 to close a communication between the water inflow port 21 and the water outflow port 23. When the piston 3 slides in the other axial direction to leave from the seat surface 2a, to open the communication between the water inflow port 21 and the water outflow port 23.  The pressure counteracting means comprises a pressure counteracting chamber 4 formed on the other side of the piston 3 and a communication passage 4a for providing a communication between the pressure counteracting chamber 4 and the one side of the piston 3.

Title: Aligner
Inventor: HAYASHI YUTAKA
IPC: G03F7/20
Filed: 1995-07-10
Abstract: PROBLEM TO BE SOLVED: To precisely measure the position of an XY stage by allowing air whose temperature is adjusted to blow nearly in parallel with the upper surface of the XY stage to optical paths for measuring length in directions X and Y from an oblique direction. SOLUTION: A wafer 3 is placed and a reflection mirror 12 measuring length in a direction X and a reflection mirror 14 measuring length in a direction Y are stuck on the upper surface of the XY stage 5. An air conditioner 17 is set obliquely to the directions X and Y, respectively. Air flow blowing from the air conditioner IT to the XY stage 5 forms various passages. Namely, the air flow passes through a gap between the reflection mirrors 12 and 14 or it hits against the side surface of the stage 5 to cross the optical path 11' or the optical path 13' or it directly crosses the optical path 11' or the optical path 13', which occurs frequently. In any case, the flow of the air is smooth and turbulence is hardly caused.  Therefore, the fluctuation of the air and irregular temperature are hardly caused, and the adverse influence such as the irregular refractive index in the air around the XY stage is eliminated.

Title: Data transmission system
Inventor: HIROSE YUKIHIKO
IPC: G06F13/36
Filed: 1985-08-06
Abstract: PURPOSE:To improve efficiency of use of a standard bus by adding a latch for data-holding to an information processor wherein the data of short word- length are processed thereby to latch the data of word-length difference when executing data transmission and by transmitting the latched data along with the last data when transmitting the last data. CONSTITUTION:The latch 1a and a buffer 2a in an I/O controller 4a are used for transmitting a data of high-order eight bits while the latch 1b and a buffer 2b are for transmitting a data of low-order eight bits. When the I/O controller 4a inputs the data of a memory board 4b, the high-order-eight-bit data and the low-order-eight-bit data are inputted by an RD signal from a data bus 3a, and the former data is latched but the altter one is internally processed. The standard bus is, at this point of time, is made free. Then the latched data is internally processed. When outputting, the low-order-eight-bit data is latched and then is outputted with the high-order one into the data bus 3a by a WR signal. However, the data bus 3a is made free as long as the low-order-eight-bit data is being latched.

Title: Fuel injection timing control device in electronic fuel injection device
Inventor: MOCHIZUKI KENJI
IPC: F02P5/15
Filed: 1982-10-01
Abstract: PURPOSE:To prevent a blow back of injected fuel by providing such an arrangement that the timing of fuel injection is delayed later than the timing of spark ignition in a low engine speed range, the delayed time of the fuel injection timing being gradually reduced in association with the increase of engine speed, and the delayed time is made zero in a high engine speed range. CONSTITUTION:In case of a low engine speed lower than about 150r.p.m., the delayed time TID of fuel injection from the timing of spark ignition is fixed to about 100ms. In a range from about 150 to 2,000r.p.m., the time TID is set to a value half the time of the period of ignition pulse. In a range from 2,000 to 4,000r.p.m., the time TID is set to a value obtained by subtracting a half of the period of about 4,000r.p.m. from the ignition pulse period, and in a range more than 4,000r.p.m., the time TID is made zero. With this arrangement, no blow back of fuel is brought about since the timing of starting of fuel injection is delayed substantially until the valve opening time of an intake-air valve, in a low engine speed range. Further, the response of the engine in a high engine speed range is improved.

IPC: B41J2/165
Filed: 1988-07-13
Abstract: PURPOSE:To recover and remove an ink applied in the vicinity of an ink discharge port of a nozzle to prevent the application of the ink to a nozzle surface and a recording medium caused by a carriage running by bringing an ink absorbing member into contact with residual ink drips on a head face when a head is disposed on a predetermined position. CONSTITUTION:After the completion of capping, an absorber lever 41 is projected from a recovery system 38 toward a head to bring the upper part of a porous absorber 34 into contact with residual ink drips. In this manner, the ink drips 40 are absorbed into the porous absorber 34 and, thus, a nozzle face is cleaned. The ink absorbed into the porous absorber 34 is recovered into a waste ink absorber 33A by a capillary force. Since the ink drips 40 can be removed as mentioned above, an ink stain caused by the ink drips 40 never occurs even when a carriage 2 is traveled.

Abstract: PURPOSE:To facilitate making the device small-sized, to prevent a break of an optical fiber and to improve the reliability by constituting the device including the first and the second converging optical transmission bodies and a member having rugged faces between them. CONSTITUTION:The light propagated in a core of an optical fiber 301 is made incident to the first converging optical transmission body 311 and becomes a thick parallel light having a beam diameter of about 1mm. in the exit end, because the length of the optical transmission body 311 is 1/4 pitch. This parallel light is made incident to a glass plate 320 where rugged faces 321 and 322 are formed on both faces and is subjected to mode conversion. Since sufficient intermode coupling is generated in the light transmitted through the glass plate 320, the light is converged by the second converging optical transmission body 312 to have a more uniform inter-mode distribution and is coupled to an optical fiber 302 efficiently. Thus, the production is easy, and a small-sized and lightweight constitution and a small insertion loss are attained, and the reliability is improved, and the device is made inexpensive.
