Title: Ignition timing control unit for internal combustion engine
Inventor: KOMURASAKI SATORU
IPC: F02P5/153
Filed: 1981-03-10
Abstract: PURPOSE:To stabilize an ignition timing when the car speed is below a specified value, by suspending the ignition timing control function via a knocking signal, leaving only a switching circuit system alive. CONSTITUTION:A constitution is established by providing a phase shift suspending circuit 14 as well as a car speed detecting circuit 13 in such a way that, if the car speed is below a prescribed one, a signal from a car-speed sensor 15 enters the phase shift suspension circuit 14 while the ignition timing control voltage from an integrator 7 does not enter a phase shifter 8. With these contrivances, when the car speed is below the prescribed one, the ignition timing control function via a knocking signal from an acceleration sensor 1 is suspended, leaving only a switching circuit 11 system alive, which gives a stable ignition timing to a driving range, that is subject to knocking, in order to obtain an effective engine operation.

Title: Connection method of clutch of mechanical supercharger for automobile
Inventor: HORI ZENNA
IPC: F02B39/12
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To effectively reduce shocks generated at the time of connecting a clutch. SOLUTION: In this method, a discharge side 2 and a suction side 1 of a supercharger are connected through a bypass passage 8 which has a bypass valve 9 for instantly opening and closing the bypass passage 8. Immediately before connecting a clutch 7 for driving rotors 4, 5 of the supercharger, the bypass valve 9 is opened to communicate the discharge side 2 with the suction side 1 thereby to release pressure. Accordingly, a ratio of discharge pressure to suction pressure becomes small to eliminate compression load and to decrease dynamic friction torque, resulting in effectively reducing shocks at the time of connecting the clutch 7.

Title: Controller for electric rolling stock
Inventor: IIDA TAKASHI
IPC: H02H9/02
Filed: 1994-03-08
Abstract: PURPOSE:To suppress the flow of an overcurrent during short-circuit accident and to prevent the occurrence of burning by connecting a current limiting element to a load in series immediately after the load for a filter capacitor. CONSTITUTION:If a short-circuit accident occurs at an inverter 8 or a main motor 9 as a load, an excessive short-circuit current begins to flow to the inverter 8. At this time, if an excessive current flows to a current limiting element 11, then the current limiting element 11 indicates quenching characteristics thereby indicating a large impedance against the excessive current and suppressing the flow of the excessive current to the inverter 8. Then, a high speed circuit breaker 4 detects the flow of a large current at the input side and performs a breaking operation. By doing this, flowing of the excessive current to the circuit element of the inverter 8 is effectively suppressed during a short-circuit accident, and also the occurrence of burning and other troubles can be prevented.

Title: Grantry type rope locking device for walking crane
Inventor: SATO MAKOTO
IPC: B66C23/88
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To prevent a rope locking device from adversely affecting the life of the rope of a walking crane, by turning the portal stanchion of the crane being moved in posture to keep away from the rope. SOLUTION: When a box boom extends, an n-stage boom 4n and an (n-1)- stage boom 4n-1 separate from each other to separate a portal stanchion 11 from a rod 12. The stanchion 11 thus separated from the rod 12 that normally forces it down automatically rises to its upright position defined by a stopper 17 by means of the turning force of a torsion spring. When the box boom telescopes, on the other hand, the n-stage boom 4n and the (n-1)-stage boom 4n-1 move toward each other to bring the stanchion 11 into contact with the rod 12. Upon the telescopic motion of the box boom to the limit, the rod 12 forces the stanchion 11 down. The stanchion 11 is thus turned down in posture to keep away from the rod 12 while the crane is moved.

Title: Driving circuit for power transistor
Inventor: SUGIMOTO TATSUSHI
IPC: H02M7/537
Filed: 1979-03-30
Abstract: PURPOSE:To simplify the driving circuit of a power transistor by employing the input signal and the reverse bias signal obtained from the signal with a fixed time range due to one-shot multivibrator following thereof. CONSTITUTION:When input signal is applied to the terminal 9, the output terminal Q of a one-shot multivibrator 5 gets the output with a fixed time width depending on the resistance 3c and the capacitor 6, which is sent to the transistor 8b. On the other hand, as the input signal constitutes the base input of the transistor 8a, the secondary winding 12a of the transformer 7a gets the same output as the input signal whereby the secondary winding 12b of the transformer 7b receives a negative signal inverted in the output of the multivibrator 5. In addition, with the secondary windings 12a and 12b connected in series, the input signal and a signal with a fixed time width in the reverse bias following thereof are applied on the base of the power transistor 1a thereby allowing the transistor 1a to be quickly shut off from the state of conduction. This eliminates any reverse bias power source thereby simplifying the drive circuit.

Inventor: TOTSUKA TAKASHI
IPC: F16K31/46
Filed: 1995-01-17
Abstract: PURPOSE: To improve the durability and reliability of a valve seal part by fixing an opening end at an upper end of a bag-shaped net filter to filter foreign matter in the drain in a tank to an inlet part communicated with the tank in the upper void space for storage of water by a valve spring, and storing it in the upper void space. CONSTITUTION: A bag-shaped net filter 36 is stored in an upper void space 18 of a cock body 16. The net filter 36 is preferably the non-woven fabric or net of resin fiber having polygonal passages of 0.5-0.2mm in side length because the size of the largest chip which can damage the rubber seal 26 of valve components 24 is generally larger than the columnar piece of square section of 0.5mm in side length and the shape is infinite. The net filter 36 is externally fitted to a valve spring 34, and an opening edge 36' at the upper end is locked to a stepped part 32 in the vicinity of the upper end of the upper void space 18 by a valve spring 34. A drain cock 10 filters foreign matters in the drain into the net filter 36 when the drain in the upper void space 18 is discharged from a discharge passage 20 by pushing up a valve member 22.  Thus, the sealability is prevented from being damaged with a foreign matter.

Title: Thin film transistor
Inventor: KUSUDA YUKIHISA
IPC: G02F1/1368
Filed: 1987-02-20
Abstract: PURPOSE:To reduce the amount of scatter in a voltage that is transitional to ON condition of a device by preparing composite films N where a semiconduc tor film K having the second conductivity type or a semiconductor film L is combined with a semiconductor film M having the first conductivity type be tween the first high conductive film and the semiconductor film. CONSTITUTION:Composite films N are prepared by combining a semiconductor film K having the second conductivity type or a semiconductor film L with a semiconductor film M having the first conductivity type where impurities are introduced in an intrinsic or low concentrated state between the first high conductive film A and the semiconductor film B. As a P-type semiconductor film 110 is included, the P-type semiconductor film 110 and n<->-type or intrinsic type semiconductor 8 are in the state of reversed bias and an electron current is stopped by the P-type semiconductor film 110 and then its current almost never flow from biases 61a-61d to a collector 62 under OFF condition.

Filed: 1993-02-26
Abstract: PURPOSE:To reduce the inter-station carrier frequency difference at a high speed and in a limited period despite the deterioration of C/N of a received burst signal. CONSTITUTION:The 2nd narrow BPF 11I and 11Q which have the pass band widths that transmit only the single frequency component corresponding to the frequency of a desired carrier are provided in addition to the 1st BPF 4I and 4Q which have the pass band widths that transmit the modulated wave bands and also eliminate the unnecessary frequency components serving as the disturbance waves like the contiguous waves, etc. Then the filter switching circuits 12 and 13 undergo the switch control by the switch control signal SWC received from a switch control circuit 14. Thus the filters 11I and 11Q are selected during the reception of a carrier reproducing code CR, and the demodulated signals are filtered.

Title: Manufacture of semiconductor device

IPC: H01L21/316
Filed: 1985-02-27
Abstract: PURPOSE:To avoid the disconnection failure of metallic wirings by flattening the interlayer insulation film by filling its steps, by providing the process of forming an insulation film over a substrate with semiconductor elements and the process of forming an Si oxide film containing phosphorus and boron so as to fill the steps of the insulation film. CONSTITUTION:A PSG film 7 is formed over the whole surface as the interlayer insulation film by CVD. At this step, steps are generated on the surface of the PSG film 7. An overhang 8 and a constriction 9 are formed in the direction of the side surface of a poly Si gate electrode 4. Next, a Si compound solution 10 containing phosphorus and boron is applied so as to fill steps of the PSG film 7 and then calcined into a BPSG film 11. The flowing temperature of this film 11 is lower than that of a PSG film: it flows by calcination and flattens by filling the steps. At this time, cracks hardly generate in the BPSG film 11. Since boron is diffused to the surface of the PSG film 7 at the time of calcination of the film 11, flowing is caused by the decrease in flowing tempera ture of the surface layer. The surface layer flows particularly at the overhang 8 and is further flattened.
