Title: Method of molding ats ground unit or the like with resin
Inventor: MIYAGAWA NANAO
IPC: G01S13/74
Filed: 1979-03-14
Abstract: PURPOSE: To stably mold an ATS ground unit, by coating a coil with resin to pervent the deformation of the coil, thereafter coupling the coil to a printed circuit board, an outside cable or the like and integrally molding these members with resin.  
     CONSTITUTION: A coiled wire 3 and lead wires 4 are dipped in a hardener-containing resin except for the ends of the lead wires as the coiled wire 3 and the lead wires 4 are shaped by coil frames 1, 1. A resin-coated coil 5 is thus manufactured. As a result, the coil is not deformed and the resonance frequency, vibration coefficient Q, etc. do not change in a succeeding molding process. A printed circuit board 9 is coupled to the coil 5. The lead wires 8 of the board 9 are connected to an outside cable 15. The oscillation resonance frequency of the coil is adjusted by a resistor, a capacitor or the like on the circuit board 9. These members are integrally shaped with injected resin by a metal mold and a metal mold lid 11. An ATS ground unit of high reliability can thus be molded. The resonance frequency of the unit does not change after the molding. Since the resin is not dividedly injected, secular exfoliation does not occure on the unit.

Title: Exhaust gas sensor for semiconductor
Inventor: YOSHIDA YUTAKA
IPC: G01N27/12
Filed: 1988-02-09
Abstract: PURPOSE:To suppress deterioration in performance due to an exhaust gas without any variation in the performance with the fitting direction by bringing the exhaust gas into contact with a semiconductor in an invariably constant direction by a protector which has a nearly conic internal space. CONSTITUTION:When the exhaust gas G is run through an exhaust pipe 8, part of the exhaust part G is admitted to the lower part 31 of the internal space 3 from an exhaust gas intake 4. Then the exhaust gas G becomes a vortex flow around an exhaust cylinder 5 in a constant direction by a tongue piece 41 to rise. The internal space 3 is nearly conic, so the exhaust gas is guided to the upper part 32 while increasing in flow rate to contact the semiconductor element 11. During this period, the exhaust gas G is cooled and water and lead in it are separated by being trapped on the internal wall surface of the protector 2. Consequently, when the exhaust gas G contacts the semiconductor element 11, the water is removed from the exhaust gas, which is cooled to some extent. Consequently, the performance never varies with the fitting direction of the sensor and the deterioration in the performance due to the exhaust gas is suppressed.

Abstract: PURPOSE:To attain the stable working of a semiconductor device with no mutual interference of load by providing exclusively a voltage limiter in response to the actuation and the type of the connected load and controlling the working capacity. CONSTITUTION:The voltage limiter circuits CC1-CCn including the drive capacity control circuits produce the internal power supply voltages V01-V0n suited to each load from the external power supply voltage VCC based on voltages Vn1-VLn.

These signals VF1-VFn choose optionally various signal forms such as the mere DC voltage, pulse signals, etc., in accordance with each case. here the levels of VL1-VLn produced by reference voltages VR1-VRn are set in response to the loads Z1-Zn. Thus it is possible to avoid the voltage fluctuation due to the mutual load interference even in case the loads Z1-Zn work at random owing to load drive pulses phi1-phin since an exclusive voltage limiter is provided to each load.
