Title: Thin-film magnetic head
Inventor: YOSHIDA MAKOTO
IPC: G11B5/31
Filed: 1993-04-12
Abstract: PURPOSE:To obtain a thin-film magnetic head having an induction-type magnetic sensing element suitable for high-density recording by partly eliminating the tip of a pole part so that the tip is not parallel to a gap film on the side opposite to the side of the gap film. CONSTITUTION:A lower magnetic film 21 and upper magnetic film 23 have, in the tip faces, a lower pole part P1 and upper pole part P2 facing each other via gap film 22. The tip faces of the pole parts P1 and P2 appear in air bearing surfaces 103, 104. The pole part P1 has a recess 105 and is formed when the tip face of the pole part is partly eliminated on the side opposite to the side of the film 22. The recess 105 is not parallel to the film 22 in the end rim being the boundary with the tip face. The pole part P2 also has a recess 106 in like manner and is formed when the pole tip face is partly eliminated on the side opposite to the side of the film 22. The recess 106 is not parallel to the film 22 in the end rim being the boundary with the tip face. This structure is equivalent to the case in which the magnetic properties of the pole part P1 or P2 are gradually lowered along the travelling direction of a magnetic recording medium so that a pseudo gap disappears.

Title: Control system for picture processing circuit
Inventor: INUKAI TSUNEYASU
IPC: H04N1/40
Filed: 1988-05-06
Abstract: PURPOSE:To increase the picture processing speed and at the same time to facilitate the read/write control of a line memory for simplification of a picture processing circuit by inhibiting the read/write switching action of the line memory before the processing is through with one line. CONSTITUTION:The latest input picture data is simultaneously written into one of the line memories 11 that stores the oldest picture data and into the corresponding one of line registers 12. Then the picture data stored in a line memory other than the said one is written into the register 12 corresponding to said line memory. Then the picture element data on the register 12 and the signal showing the array state of said data in terms of time series are supplied to a picture arithmetic memory circuit 15 for acquisition of a processed picture. The procedure proceeds to the next line when the processing is through with one line and the same processing operation is carried out. Thus the picture processing speed is increased and a picture processing circuit is simplified.

Title: Sodium-sulfur battery
Inventor: WADA HAJIME
IPC: H01M10/39
Filed: 1988-05-06
Abstract: PURPOSE:To cause the solid layer of sodium sulfide to be formed rapidly when a solid electrolyte is broken and minimize the heating value of the battery by covering all over the surface of the solid electrolyte with a porous material and causing the negative electrode side space to be more negative in pressure than the positive electrode side space. CONSTITUTION:Surfaces on both sides of a wall of a solid electrolyte 7 are covered closely by a porous material 5 filled with an active material of each electrode and the negative electrode side space storing sodium is kept to be more negative in pressure than the positive electrode side space. When the solid electrolyte is broken, very small cracks are produced on the solid electrolyte 7 at the beginning of the breakage and active materials of positive and negative electrodes move into opposite side region through these cracks. The speed of the positive electrode active material flowing into the negative electrode side becomes small because the porous material suppresses the motion of the fluid for the liquid active material. The heating value of the active material can be held small because the amount of the flow is small, and the sodium sulfide produced by a reaction in the negative electrode side is solidified rapidly to seal the further flow of the positive active material into the negative electrode side so that the battery will never generate heat any more.

Title: Device for controlling parallel hybrid vehicle
Inventor: SUMI YASUO
IPC: B60L50/16
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent engagement shocks at the time of the start of a vehicle and to improve accelerating capability, while achieving its compactness in a parallel hybrid vehicle provided with an engine and a motor/generator as a rotational driving source. SOLUTION: An engine 1, a motor/generator 2 and a transmission 4 are each connected to the first shaft 31, a second shaft 32 and the third shaft of a differential gear 3 respectively. The engagement of the first and second shafts are made possible with a direct-coupled clutch 36. At the start in the idling state of the engine 1, the motor/generator 2 is controlled in a reverse generating state to maintain the engine speed at a target speed close to the idling speed. When the motor/generator 2 goes into a normal state after a vehicle has started, it is controlled as an electric motor to maintain the target speed of the engine. When the engine speed becomes equal to the motor/generator speed, the direct- coupled clutch 36 is engaged, so that the occurrence of an engagement shock is prevented and the period of the driving time by the motor/generator 2 is shortened.

Title: Phase discrimination circuit
Inventor: TAKADA MASAKI
IPC: H03K5/1532
Filed: 1994-05-24
Abstract: PURPOSE:To reduce mounting area even when plural input signals are used by allowing a clock extract circuit to sample a received signal based on an (n)-phase clock whose period is a half of that of the received signal and discriminating between which clocks a change point of the received signal is in existence based on the sampling result thereby attaining circuit integration. CONSTITUTION:When a received signal is sampled by using clocks C0, C1, C2, C3 in an input sample circuit 11, the result is indicated as A, B, C, D. When the sampling results are exclusively ORed by using an arithmetic circuit 12, since the clocks C0, C1 are phase-shifted by 1/4 in the results A, B and the waveform is rugged, the ruggedness is eliminated in the result E by sampling again the level waveform of level 1 by using the clock C3 through the use of a phase adjustment circuit 13, the ruggedness is eliminated in the result E and the result E is at a level 1 in the timing of the clock C3 and sampling results F-H remain 0 by sampling again the exclusively ORed results between the results B and C, between the results C and D and between the results D and A, then a change point is in existence between the clocks C0 and C1 is discriminated.

Title: Stop controller for unmanned carrier
Inventor: KATO MASATSUGU
IPC: G05D1/02
Filed: 1987-05-01
Abstract: PURPOSE:To quickly and accurately stop an unmanned carrier at a target position by driving the carrier in the opposite direction in case a mark detecting means detects no target mark yet when the stop of the carrier is detected. CONSTITUTION:When an arrival detecting means M6 detects that an unmanned carrier M4 reached a target mark position, a stop command output means M7 works to deliver a stop command to a drive device M3. Thus the carrier M4 tries to stop. The stop of the carrier M4 is detected by a stop detecting means M8. Under such conditions, if a mark detecting means M5 does not detect a mark M2 put on a drive course M1 yet, an opposite direction drive command means M9 works to deliver an opposite direction command to the M3 since the M4 passed through the target mark position. Thus it is just required to actuate the means M7 for the first time after the M4 is driven at a high speed and its arrival at the target mark position is detected. Therefore the driving speed of the M4 is improved.

Title: Thermal head
Inventor: DOI ATSUHIRO
IPC: B41J2/345
Filed: 1985-05-22
Abstract: PURPOSE:To enable image recording at easily obtainable gradation under no adverse effect of adjacent pixels by providing each heating element composed of plural segmented chips and reducing the total area of heating elements compared to the area of a pixel region. CONSTITUTION:A pixel region 11-1n of a thermal head 1 is divided in two parts respectively and heating elements 31A, 31B- 3nA, 3nB whose total area is smaller than the pixel region 11-1n are arranged on the thermal head 1. Under this design, a temperature distribution is provided in a single pixel when energy is applied and said temperature distribution is not overlapped to that generated by heat of the heating elements of adjacent pixels. Consequently, when energy is applied to each heating element, image output density D is not susceptible of any adverse effect by the adjoining pixels. Thus it is possible to moderate the optical density variation of an image output against a charged energy, facilitate gradation output and perform image recording free from the adverse effect of the adjoining pixels.

Title: Bicmos semiconductor device
Inventor: TAGAMI YUICHI
IPC: H01L29/73
Filed: 1989-04-29
Abstract: PURPOSE:To easily obtain an arbitrary resistance value by means of a gate length and a gate width and to obtain a small-sized BiCMOS semiconductor device by a method wherein a second P-channel MOS transistor whose gate has been grounded is formed as a resistance for base charge extraction use of a bipolar transistor. CONSTITUTION:A P-channel MOSFET Q4 for base charge extraction use is connected between a base and an emitter of an NPN bipolar transistor Q1. A gate of the P-channel MOSFET Q4 is connected to a ground terminal 4. Since the gate of the P-channel MOS transistor is fixed at a ground potential, this transistor functions as a resistance for base charge extraction use of the bipolar transistor. An arbitrary resistance value for the second P-channel MOS transistor can be obtained easily by means of a gate length and a gate width; a resistance value of several kOMEGA which is required as a resistance for base charge extraction use can be obtained by an occupied area which is much smaller than that of a diffusion resistance.

IPC: E03C1/05
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To provide an automatic water feeder equipped to stop water feed so that a user can do it at will. SOLUTION: During a closing of an open water feeder valve 6, a sensor stops its operation for a specified time Tw1 from a time t4 when his/her hand is moved out from a detection area. During the time Tw1, even if his/her hand re-enters the detection area after the time t4, a detection signal causes no alteration, so that since an opening/closing signal that opens the water feeder valve 6 is not outputted thereto, the water feeder valve 6 goes on with the closing even if his/her hand re-enters the detection area during the closing thereof. Accordingly, even if his/her hand reenters the detection area during the closing of the water feeder valve 6, water is prevented from being re-fed against his/her will, and thus a user can stop the water feed at will.
