Title: Mis field-effect transistor and manufacture thereof
Inventor: SAKURAI JUNJI
IPC: H01L29/78
Filed: 1986-09-19
Abstract: PURPOSE:To suppress the extension to a channel region thereby to enhance the breakdown strength while obtaining the width of a depleted layer formed on a region junction by reducing the impurity concentration of source, drain regions lower than that of the channel region. CONSTITUTION:In an MOSFET, the impurity concentration of source, drain regions 12 is reduced lower than that of a substrate 11 and a channel region 13, the extension of a depleted layer formed on the junction of the region 12 of the region 13 side can be ignored by applying a voltage, it is extended to the side of the region 12 to obtain the width. When this MOSFET is manufactured, the implantation of an impurity to the region 13 is executed after that of the source, drain regions 12 to reduce the impurity concentration lower than that of the region 13 by forming the regions 12.

Title: Cylindrical valve unit
Inventor: KAWABE TATSU
IPC: F16K11/07
Filed: 1982-12-17
Abstract: PURPOSE:To prevent the life of a cylindrical valve unit from being shortened due to wear, by alternately piling up a plurality of sealing rings and a plurality of coupling rings on each other and clamping them together to form a cylindrical body. CONSTITUTION:Sealing rings 3, 3a-3d and coupling rings 4, 4a-4d are alternately piled up between clamping rings 1, 2. These piled-up elements are secured together by assembly bolts 5 extending through lobes 2a provided at the same interval on the peripheral surfaces of the clamping rings 1, 2, so that a cylindrical body 6 is formed. As a result, a sealing member does not need to be secured at the side of a piston valve and they are brought into contact with each other only in the stopped position of the piston valve. For that reason, wear under motion is prevented, so that the life is kept from being shortened due to the wear.

Title: Vehicle height detector for automobile
Inventor: SHIMOMURA SETSUHIRO
IPC: G01B11/00
Filed: 1982-12-16
Abstract: PURPOSE:To obtain a high reliability required for a vehicle height detector receiving vibration and impact by arranging a light emitting element and a light receiving element opposite to an outer cylinder supported on the side of a body while an inner cylinder acting as slide member supported on the side of a wheel intercepts light to the light receiving element. CONSTITUTION:A link 4a at tone end is supported on the side of a body 1 while a link 4b at the other end supported on a shaft of a wheel 3 and a vehicle height detector 4 is displaced with the reduction of a suspension 2 in such a manner as to move in or out freely to detect the vehicle height. In the vehicle height detector 4, light receiving elements 42b-44b receive light from light emitting elements 42a-44a when an inner cylinder 41 is pulled out to its maximum from an outer cylinder 40 and as the inner cylinder 41 is inserted thereinto, the light to the light receiving element is intercepted gradually. Thus, changes in the relative displacement between the outer cylinder 40 and the inner cylinder 41 is obtained depending on the output state of the light receiving elements 42b-44b to enable the detection of the vehicle height.

Title: Drive method for single spindle type winder
Inventor: YAMAMOTO MASAO
IPC: B65H54/74
Filed: 1990-08-27
Abstract: PURPOSE:To drive and control the inverter of each spindle through a single control device by generating a synchronous signal by means of which all spindles are controlled, inputting the synchronous signal to the inverter to regulate rotation of a traverse motor, and controlling an edge control motor. CONSTITUTION:A control device 15 generates a synchronous signal by means of which all spindles are controlled. When a switch 19 is turned ON, a winding motor 11 is forced to rise to constant speed rotation indicated by an inverter 13. First, a synchrowaveform shown in (a) is formed, during a fall, a drive signal shown in (e) is inputted to an edge control motor 17, and a traverse range is changed from T0 to T1. Since the end surface of a package is wound, as shown in (f), in a state that a periodically narrow traverse range T1 is switched to an ordinary traverse range T0 the thickness of an end surface is prevented from increasing. The synchrowaveform is inputted to an inverter 14 and running of a motor 12 is regulated so that during a rise, boosting is effected from a lowermost speed RL and during a fall, deceleration is effected from a highmost speed RH.

Title: Safety device of burner
Inventor: KAWAHARA KAZUNARI
IPC: F23N5/10
Filed: 1986-09-19
Abstract: PURPOSE:To stop the combustion of the burner when the burner is used continuously for a long time to supplement an incomplete combustion preventing device by providing a timer circuit which operates a solenoid valve disposed in a gas passage of the burner when a switch which is turned ON and OFF in linkage with the igniting operation is turned ON, and turns OFF the solenoid valve after the lapse of a predetermined time. CONSTITUTION:When a switch 2 is turned ON upon ignition operation a current is allowed to flow to a solenoid valve 8 by detecting a difference in electromotive force between a pilot thermocouple 4 and a reverse bias thermocouple 5. Simultaneously, a timer circuit 9 operates. A reference voltage is produced by resistors r1 and r2 on the non-inverting input side of an operational amplifier IC, and a CR charging circuit is produced by a resistor r3 and a capacitor C on the inverting side of the operational amplifier IC. When the switch 2 is turned ON to start changing of the capacitor, and the inverting input voltage of the operational amplifier IC becomes higher than a reference voltage, the output of the operational amplifier IC becomes from a high level to a low level, and an AC output from a comparator 6 is erased. Hence, no current flows to the solenoid valve 8, and as a result the valve 8 is closed to stop the combustion. Accordingly, by selecting the constants of the resistor r3 and the capacitor C, the switch 2 is turned ON and the time until the solenoid valve 8 is closed can be suitably selected.

Title: Clock dial synchronous system
Inventor: MURAGUCHI HIDEAKI
IPC: G04G7/00
Filed: 1990-08-24
Abstract: PURPOSE:To facilitate the prevention of an instantaneous second phase shift at the time of signal synchronization, a second phase shift due to instantaneous stoppage and an excessive second hand advance due to an unnecessary trigger signal respectively by providing an external judgement section for second stability to confirm the stability of a second pulse in the dial of a station clock. CONSTITUTION:An external input check counter 1 and an internal second counter 2 add pulses outputted from an interval timer 4 at intervals of 1/100 second. When a counter value reaches 100, the counters 1 and 2 are reset to zero, and the data of seconds is updated. When there is any interruption from a station clock 6, the counter 1 sets zero, and stores a counter value in registers 7a to 7c indicated by a pointer. The aforesaid setting and storing process is repeated three times, and when all counter values in the registers 7a to 7c are all equal to 99 types or above, but equal to or less than 102 types, a judgement section judges that interruption is externally taking place for the data of seconds, and outputs a synchronizing signal. The counter 2 is thereby made to reset the counter value thereof and synchronized with the counter 1.
