Title: Manufacture of metal vapor discharge lamp
Inventor: WATANABE KEIJI
IPC: H01J9/395
Filed: 1980-03-14
Abstract: PURPOSE:To prevent a decrease of gas pressure in a metal vapor discharge lamp, by introducing gas for lowering surge voltage in an outer tube, discharging the gas in the outer tube and then exhausting the gas again sealing the above described gas in the outer tube. CONSTITUTION:After work of assembly for a luminous tube 1, bimetal 4, filament 5 and the like in an outer tube 7, vacuumizing exhaust work is performed in an outer tube exhaust process, then sealing gas is introduced into the outer tube 7 to discharge the gas in the inside by a Tesla coil from the outside of the outer tube, and then said gas is exhausted to again seal the sealing gas in the outer tube 7 at prescribed pressure. The sealing gas, which is for lowering surge voltage generated when the bimetal is operated, is introduced into the outer tube 7 and electric discharge, then a generated ion is allowed to hit glass surfaces, thus the subsequently sealed gas is prevented from being absorbed and stored in the glass surfaces of the outer tube.

IPC: B64D43/02
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To provide an airspeed measuring system which can accurately and easily measure airspeed even in the low-speed flight. SOLUTION: A measured value Vg outputted from a receiver 2 of a GPS (global positioning system) and a measured value Va outputted from a Pitot's tube 3 are sent to a processing section 4. When |measured value Va| > specified VT, the processing section 4 uses the measured value Va as intact as airspeed vector Vp. The measured value Vg - measured value Va as obtained the moment |measured value Va| <= specified value VT is given is stored into a memory 6 as wind velocity vector VW. When the |measured value Va| <=specified value VT, the measured value Vg - wind velocity vector VW is used as air speed vector Vp. This enables easily and accurately measuring of the airspeed of a helicoptor even in the low-speed flight as given by | measured Vaf| <= specified value.

Title: Capacitance type acceleration sensor
Inventor: NAGATA TOMIO
IPC: G01P15/125
Filed: 1991-01-31
Abstract: PURPOSE:To return an abnormal measuring condition to the normal measuring condition when a moving electrode of a capacitance type acceleration sensor is attracted to an opposed fixed electrode by detecting the abnormal measuring condition to release the attraction thereof. CONSTITUTION:A DC voltage V0 is applied between both electrodes of a capacitance type acceleration sensor and a voltage Vs related to a capacitance Cv is outputted through a Schumitt trigger circuit 61 and a f/V converter 62. The voltage Vs is compared with a reference voltage Vref lower slightly than the maximum voltage value as given when both the electrodes are attracted using a comparator 64. When the above voltage Vs is larger than the reference voltage Vref, a single pulse with a pulse width (t) is outputted from a one-shot multivibrator 65. The output pulse make a normally closed switch Sv on a wire with which a DC voltage V0 is applied between both the electrodes open temporarily to cut the DC voltage V0. Thus, the capacitance type acceleration sensor is returned to the normal measuring condition immediately even when attraction occurs between both the electrodes by a static power under an excessive load.

This is used as a majority decision element, the control circuit 3 checks the weight CT of a syndrome is equal to the threshold value ''0'' or not when the threshold value is ''0''. When not equal to, the control circuit 3 shifts the shift register 1, the threshold value is brought into ''1'' so as to check whether or not the syndrome is equal. When equal to the threshold value, the correction circuit 4 is controlled so as to attain correction. When the reception code not matched with the threshold value does not exist, the shift operations of the prescribed number of times is restored to the original code.

Title: Manufacturing method of cam shaft
Inventor: NISHIMURA TOSHIFUMI
IPC: F16H53/02
Filed: 1981-03-10
Abstract: PURPOSE:To prevent breakage at any portion of cam by using a bulge metal die provided with an elastic member applied to the cam supporting surface, and applying compressive force to the elastic member when die is set up for the bulge forming process, thus maintaining initial compressive load at the area of protrusion. CONSTITUTION:The pipe material 1' is inserted in position to the fixed half of the metal die 10 of bulge process, and other half of the die 10 assembled by means of a guide pin 15, and two halves tightened up. At this moment, an elastic member 14 is squeezed between the protruding area 2 and the supporting surface 11 of cam so that initial compressive load directing inward is imposed on the protruding area of the elastic member 14. Under such condition, emulsion liquid is introduced into the pipe 1' and pressure applied forcing the pipe 1' bulge out. As the pipe bulge outward, tensile stress is generated, however, because of the initial compressive load imposed by the elastic member 14, part of the tensile stress is cancelled, so that the maximum tensile stress at the cam area 2 is considerably reduced.
