Title: Sheet paper transport apparatus
Inventor: MORINO KIYOSHI
IPC: B41J13/10
Filed: 1985-08-27
Abstract: PURPOSE:To reliably regulate the movement of a sheet in the lateral direction by providing a pair of guide plates disposed in the lateral direction of a sheet and a sensor for detecting the lateral position of the sheet. CONSTITUTION:A sheet 8 is inserted in a sheet push-in portion 9, and when the leading edge of the sheet 8 is brought into contact with a small stopper piece 12, the sheet 8 is detected by a leading edge position detecting sensor 19. On detecting the leading edge of the sheet, a stepping motor 31 of guide plate driving means 24 is started, so that a movable guide plate 21 is moved in close to a fixd guide plate 20 by rotation of a feed screw 25. When lateral direction position detecting sensors 22, 23 detect the sheet 8, the stepping motor 31 is stopped. Subsequently, a solenoid 43 of roller driving means is excited, so that a pinch roller 37 is moved in close to a feed roller 33 to clamp the sheet 8 with both rollers 33, 37. A small stopper piece 12 is retreated from a sheet path. The feed roller is driven by driving means, thereby to feed the sheet 8 between a platen and the print head 6.

Inventor: NAKAMORI YUKIO
IPC: G01B7/00
Filed: 1980-12-27
Abstract: PURPOSE:To enable manufacture of an eddy-current system displacement gauge which is excellent in heat resistance, inexpensive, and high-precise, by a method wherein a displacement signal from a detecting coil and a signal from a temperature sensor are independently processed to cause a correcting arithmetic unit to perform a temperature compensation of the displacement signal. CONSTITUTION:A displacement signal from a detecting coil and a temperature signal from a temperature sensor are independently processed to cause a correcting arithmetic unit to perform a correction of the displacement signal. For example, a coaxial cable 2, made of a compensating conductor material for thermocouple, and a displacement detecting coil 1 are connected through a thermocouple strand to form thermocouple contacts a, a'. A high-frequency power is then supplied to the thermocouple contacts by a high-frequency oscillator 3, and after a voltage at a b-point, changing corresponding to a distance between the coil and an object to be measured, is detected by means of capacitor and diode, the result is amplified by an amplifier 6. Meanwhile, the result is inputted to a temperature compensation circuit 7 togetherwith a thermocouple signal processed by a filter 4 and an amplifier 5 to cause the circuit 7 to perform a temperature compensation of a displacement signal.

Title: Sequence circuit for fet bias
Inventor: ISHIDA MASATOSHI
IPC: H03F1/00
Filed: 1988-07-27
Abstract: PURPOSE:To easily delay the ON-OFF of a FET bias at low cost on a small circuit scale by providing a time constant to a sequence circuit for the FET bias itself. CONSTITUTION:A capacitor 112 is connected between the emitter of a switching transistor 105 and the junction of resistances 110 and 111. consequently, a base current does not flow in the switching transistor 105 until the capacitor 112 is charged up with the time constant determined by the resistance value of the resistance 111 and the capacity value of the capacitor 112. After the capacitor 112 is charged up, the base current of the switching transistor 105 flows, thus, the collector current of the switching transistor 105 flows and a positive power is outputted to a positive power output terminal 103. Thus, the switching time of the switching transistor 105 lengthens and the ON-OFF of the bias voltage of the drain of a FET delays.

Title: Control device of engine
Inventor: ASAYAMA YOSHIAKI
IPC: F02D9/02
Filed: 1988-07-27
Abstract: PURPOSE:To enable measurement in a wide range with good accuracy even by an air flow sensor having a narrow measuring range by providing valve opening control delay means for delaying the operation of throttle valve opening control means. CONSTITUTION:In a computer 14, a valve opening control delay device 13 keeps an opening of a throttle valve 4 in a condition before the opening and closing regardless of the operation of an accel pedal 17 during the period of a designated time since a by-pass passage switch valve 9 starts the opening and closing operation. After the lapse of a designated time, throttle valve opening control according to an output signal of an accel sensor 15 is started by a throttle valve opening control device 12. Thus, the air flow sucked in an engine 1 is kept at a value just before switching within the switching time of a by-pass passage switch valve 16, so that this value is used as the air flow value within the switching time. Accordingly, the air flow within the switching time can be known correctly independently of an output signal of an air flow sensor 7.

Title: Optical information recording medium
Inventor: NAKAMURA ITSURO
IPC: G11B7/257
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical information recording medium of a phase-change type having an excellent repetitive overwriting characteristic. SOLUTION: This phase-change type optical information recording medium is constituted by laminating at least a first dielectric protective layer 3, a recording layer 4 consisting of a phase transition material, a second dielectric protective layer 5 and a reflection layer 6 on a transparent substrate 2 and records information by non-crystallizing the recording layer by irradiation with a writing laser beam. The second dielectric protective layer of this recording medium is so formed as to consist of ZnS and at least one element among group 3b, group 4a, group 4b and group 5a elements and the oxides of the same elements. As a result, the difference in the percentage of light absorption between the amorphous state and crystalline state of the recording layer is suppressed and, therefore, the distortion of the mark shape of the recording marks at the time of overwriting is lessened.  The increase in the jitter of regenerative signals is thus suppressed.

Title: Dry etching device
Inventor: OZAKI JUN
IPC: H01L21/302
Filed: 1988-07-29
Abstract: PURPOSE:To remove a reaction product from inside of a chamber without releasing the inside of the chamber to the air by providing a supply port to supply washings into a chamber and a drain port to drain contaminated liquid produced by washing out of the chamber. CONSTITUTION:For a dry etching device, a supply port 4 at the top of a chamber 1 and a drain port 5 at the bottom are mounted, and if etching of a wafer is done in the condition where valves 4a and 5a are closed, the inside of the chamber 1 is polluted by a reaction product which is produced by halocarbon being etching gas, silicon compound being material to be etched, and organic substance being the constituent element of photoresist chemically reacting on each other in the plasma. In the case of washing the inside of the chamber 1, after etching treatment, the valve 4a is opened and nitric acid is introduced into the chamber 1 from the supply port 4. At this time, the valve 5a at the drain port 5 is closed. Since the reaction product inside the chamber 1 is dissolved by the chemical reaction with nitric acid and is washed away by the flow pressure, the valve 4a is closed and the valve 5a is opened so as to drain the nitric acid from the drain port 5. Hereby, the reaction product inside the chamber can be removed without the chamber being released to the air.
