Title: Anti-lock control device incorporated in calliper
Inventor: SHINDO EIJI
IPC: B60T8/42
Filed: 1993-12-03
Abstract: PURPOSE:To provide an anti-lock control device which has within a brake calliper a pressure reduction mechanism controlled by signals from an electronic control unit. CONSTITUTION:When a signal for holding a brake is outputted from an electronic control circuit 20, a solenoid valve 14 is made to carry a current and thereby a valve element 14b moves downwards against the pressure of a spring 14c, interrupting the communication between first 10 and second 11 passages and thus interrupting the communication between a master cylinder 2 and a fluid pressure chamber 7a through an oil passage. As a result, brake fluid pressure within the fluid pressure chamber 7a is held at the level at that time and a brake holding state is executed. When a signal for releasing the brake is outputted from the electronic control unit 20, the solenoid valve is made to carry a current to interrupt a passage, and a rotary cam 18 starts to rotate slightly after the operation of the solenoid valve, moving a pressure regulating piston downwards. As a result, the volume of a pressure regulating chamber 17 is enlarged by (V) and brake fluid is forced to flow back from the fluid pressure chamber 7a, lowering the fluid pressure of the fluid pressure chamber 7a and thus releasing the brake.

Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To realize a printer in which a variable data can be printed at a very high speed comparable with that of offset rotary press. SOLUTION: A fixed data is printed on a print sheet 30 based on a plate being fed out from a print sheet supply section and set at a plate rotating section 12.

Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for hardening gate oxide without forming a region having a low dopant concentration on the interface between the gate oxide and polysilicon. SOLUTION: Polysilicon is deposited on gate oxide 34, then, nitrogen is applied and annealing process is performed. At this point, nitrogen concentration peaks 42 and 44 exist on the interface between the single crystalline substrate 36 of the gate oxide 34 and a polysilicon gate electrode 38. Thus, the gate oxide 34 is effectively hardened. A third polysilicon gate electrode exists on the bulk of the polysilicon gate electrode. In such process, the region of the polysilicon layer having the peak nitrogen concentration is removed. Then, electronically active dopant is implanted. Instead, a new polysilicon layer may be deposited and then the electronically active dopant may be implanted. Therefore, in this method, prevention of diffusion of the electronically active dopant is eliminated.

IPC: F02B23/08
Filed: 1988-11-30
Abstract: PURPOSE:To make it possible to reduce HC by forming the inclination of a piston head side dome part toward squish area greater the less the inclination of a cylinder head side dorm part toward squish area. CONSTITUTION:Dome parts 21a, 21b are formed on the top surface part of the piston head 23 of a piston 20 inserted in a cylinder bore 3, in correspondence with dome parts 5a, 5b on a cylinder head side. The constitution is so made that the inclination of the dome parts 5a, 5b toward squish area is formed greater for portions where the inclination of the dome parts 21a, 21b is lesser. Therefore, the shape of a combustion chamber 5 is brought as much as closer to a spherical form so that the capacity of the combustion chamber can be expanded without expanding the cylinder diameter. Furthermore, since the inclination of each dome part 5a, 5b, 21a, 21b is set in a way to mutually converse their dimensions, the intrusion and propagation of flame into squish area in the expansion stroke are made easier to reduce HC.

Abstract: PURPOSE:To generate an origin signal having a required pulse width even when a fixed slit plate is not available by using the output signals of photoreceptor elements arranged in parallel in the moving direction of a slit disk and signals which are obtained by compressing the output signals and have waveforms similar to those of the output signals. CONSTITUTION:Signals 1 and 3 which are obtained by amplifying the detecting signals of two photoreceptor elements arranged in parallel at a fixed interval in the moving direction of a slit disk at a fixed amplification factor and voltage dropping signals 2 and 4 which are obtained by compressing the signals 1 and 3 by fixed levels and have waveforms similar to those of the signals 1 and 3 are generated. A high logical- level signal 9 is outputted during the period from T1 to T5 when the level of the sum signal 5 of the signals 1 and 3 exceeds a reference voltage 6, but an output signal 7 rises at the point of time T2 when the peak of the signal 1 passes and the value of the signal 2 becomes lower than that of the signal 3. In addition, another output signal 8 rises at the point of time T4 when the value of the signal 1 becomes lower than that of the signal 4. Therefore, the AND of the signals 9, 7, and 8 is computed and the points of time T2-T4 are outputted as origin signals Z. Accordingly, the point of crossing time T3 of the signals 1 and 3 is necessarily contained in the pulse width of the signals Z.

Abstract: PROBLEM TO BE SOLVED: To improve the measuring accuracy and reliability of a blood pressure value by accomplishing a proper calibration in a non-invasion blood continuous hemomanometer for measuring a blood pressure by inducing vibration in a blood vessel. SOLUTION: Vibration is induced on an artery in vivo from the surface of a human body using a vibrator 2. The propagation wave of the induced vibration is detected by a propagation wave sensor 3. Changes in phase of the detected propagation wave are calculated by an MPU6. The MPU6 judges the presence of physical motion of a subject by a displacement sensor 9 mounted on the subject. When determining any physical motion to occur in the subject, the MPU6 performs a calibration with a hemomanometer 7 for the calibration. The MPU6 determines a continuous blood pressure value from the variation of phase calculated and the results of the measurement of the blood pressure by the hemomanometer 7 for the calibration.
