Title: Master cylinder
Inventor: NAKAMURA YOSHIHIRO
IPC: B60T11/28
Filed: 1984-06-20
Abstract: PURPOSE:To certainly release a liquid pressure control valve from operation to simplify the constitution of a master cylinder by making a piston to engage the liquid pressure control valve when the master cylider piston is displaced over the preset amount of stroke during failure of one system brake circuit. CONSTITUTION:A liquid pressure control valve 16 is screwed to the discharge port of the compression chamber at the side wall of a master cylinder body 1. The needle 24 of the liquid pressure control valve 16 is equipped with an engage part 26 in one body and the end of the engage part 26 is projected into the compression chamber. On the other hand, on the end of a master cylinder piston, a needle operation release section 27 is provided. And when the piston is displaced over the preset amount of stroke during failure of the brake circuit of the front wheel side, the said needle operation release section 27 engages to the said engage part 26. This engagement rotates the needle 24 to separate it from a valve seat 23. As a result, since the compression chamber and the brake of the rear wheel maintain mutual connection constantly, liquid pressure control is not performed.

IPC: H02P6/08
Filed: 1987-05-26
Abstract: PURPOSE:To prevent an inverter circuit from falling into miscommutation, by detecting the abnormal condition of induced voltage with the control signal from among PLL control means for protective control. CONSTITUTION:Induced voltage of a synchronous motor 1 is insulatingly detected through a transformer 3. This detected output and a designated cross signal are inputted into a phase difference detection circuit 4, with which the phase difference between both of them is detected.

A PLL circuit is constituted by supplying this output to an inverter circuit 2 through an AC signal generator 7, a stop circuit 12 and a beta-control circuit 8. On the other hand, when the output of the phase difference detection circuit 4 gets to more than the preset value, the stop circuit is actuated with an abnormality detection circuit 11 to stop the beta-control circuit 8 and inverter circuit 2.

Title: Electrodeless discharge lamp apparatus
Inventor: KOBAYASHI KOICHI
IPC: H01J65/04
Filed: 1987-05-25
Abstract: PURPOSE:To maintain constant light emission on the whole area of the lamp in the caption by composing it with a bulb including at least two straight bulb portions in parallel to each other so as to form a going-around discharge path with its straight bulb portions connected to each other near the both ends thereof and also arranging a coil along this going-around discharge path. CONSTITUTION:A lamp 21 is composed in such a way that two straight bulbs 22a and 22b are arranged in parallel with each other, both are connected to each other via bridges 28 and 29 near both ends thereof to form one going- around discharge path as a space in the lamp 21 and also a coil 26 is arranged along the going-around discharge path. Therefore, when a high frequency current flows through the coil 26, an induced current Ia flowing inside the lamp 21 induced by the high frequency current flows as forming a loop in the lamp 21. In this case, even if an electric power is lowered, the induced current Ia does not form any separate short circuit-loop but always maintains a loop along the coil 26. Accordingly, constant light emission on the whole area of the lamp is maintained.

IPC: F23D3/28
Filed: 1981-08-13
Abstract: PURPOSE:To make it possible to perform fuellers burning of a wick sufficiently and extinguish fire accurately in case of oxygen deficiency by a method wherein in case an oxygen deficiency is detected by an oxygen deficiency sensor, the  supply of elecricity to a wick supporting solenoid is stopped while the solenoid  is still energized for a predetermined period of time irrespective of the stoppage  of the supply of electricity. CONSTITUTION:When a switch 24 is kept open at the time of ordinary combustion and when in that condition a knob 2 is rotated to elevate a wick in a combustion section 1, a switch 6 is closed to energize an oxygen deficiency sensor 7. In this case, when oxygen deficiency is brought about, the resistance of the sensor 7 increases to make the potential at the point (c) become lower than that at the point (d) so that the output of a differential amplifier 18 becomes negative causing a transistor 23 to turn OFF to deenergize a solenoid 5 and the wick is lowered to stop burning. Further, when a switch 24 is closed, the transistor 23 goes ON for a predetermined period of time irrespective of the output of the differential amplifier 18 and the solenoid 5 is energized to allow the combustion apparatus to burn the wick sufficiently during that period of time.

Filed: 1979-10-02
Abstract: PURPOSE:To permit a bevel-type semiconductor element to be glassivated by glassivating bevel-type semiconductor elements which have been maintained as a wafer  by means of a polycrystalline Si layer. CONSTITUTION:On a semiconductor substrate 1 being a wafer, a bevel-type semiconductor element is formed, and emitter, base and collector electrodes 8, 9 and 10 are provided. Then both main surfaces of the substrate 1 are all coated with CVDSi oxide films 11 or CVDSi nitride films 11, on which a polycrystalline Si film 12 is fromed. After the film 11 on the opposite main surface of the substrate 1 is selectively masked with wax 13, bevel etch is performed to the interface between the emitter-side Si and film 11. On doing this the substrate 1 is divided into pellets, but they are maintained as a wafer by means of the film 12. After that, the sides of each pellet which have been exposed by the bevel etch are glassivated 14. Then the film 12 is removed, and therefore the pellets having been maintained as a wafer are saparated into pieces.

Abstract: PURPOSE:To improve the characteristics and reliability of a transistor by disposing rearward the periphery of the upper face of a gate electrode by isotropically etching in case of patterning, and then forming a gate by anisotropically etching to symmetrically implant ions near the gate without offset by the shade of the electrode. CONSTITUTION:After a gate oxide film 12 is formed on a single crystal silicon substrate 11, a polycrystalline silicon layer 13 is deposited. Thereafter, it is coated with a resist 14, exposed and developed. After the layer 13 is etched by isotropically etching, it is anisotropically etched to pattern a gate 13. Then, LDDN<-> ions are implanted at an angle of numeral 16, and N<+> ions or P<+> ions are implanted to form source and drain regions. Thus, the shadow effect of the gate in case of the ion implantation is reduced, and an offset is eliminated between the ion implanted region and a gate electrode. Further, the ion implantation is symmetrically conducted to improve the characteristics and reliability of a transistor and to reduce the irregularity in the characteristics.

Filed: 1988-05-27
Abstract: PURPOSE:To obtain a reliable monitoring device of an air gap, by a method wherein a light beam is applied with a specified angle onto the surface of a rotor provided with a reflector and the position of the light beam from the reflector is converted into a signal by a linear image sensor and read. CONSTITUTION:A light from a light source 3 is transformed by a projector 5 into a strip-shaped light beam and it irradiates the surface 2 of a rotor. When a reflector 1 provided on the surface 2 turns round onto the light beam, the light beam is reflected thereby and made to enter a part of an optical fiber group 7 of a photodetecting probe 6. This incident light is converted into an electric signal by a linear image sensor 8 and sent to a reading-alarming device 9. Since the position of the light beam entering the optical fiber group 7 corresponds to an air gap, the air gap can be detected from the electric signal, and when the air gap exceeds a prescribed value, an alarm is issued. According to this constitution, a reliable monitoring device of the air gap can be obtained.
