Title: Controller for dc series motor
Inventor: HAMADA HIRONOBU
IPC: B60L15/20
Filed: 1989-06-26
Abstract: PURPOSE:To prevent degradation of transient rectifying performance without sacrificing steady rectifying performance by performing field weakening control through a pure resistor circuit under a steady state and performing field weakening control through a circuit a containing reactor component under a transient state. CONSTITUTION:Under steady state, an instantaneous power interruption detecting means 19 does not detect voltage fluctuation. Consequently, a thyristor 13 is turned on while a thyristor 16 is turned off and a portion of current to be fed to a field winding 7 flows through a weakening field contactor 9 and the thyristor 13 to a resistor 14 thus producing weakening field from a DC series motor 6. Upon instantaneous power interruption due to disconnection of pantograph 1, the thyristor 13 is turned off while the thyristor 16 is turned on by the output from the instantaneous power interruption detecting means 19 and a portion of current to be fed to the field winding 7 flows through the weakening field contactor 9, the thyristor 16 and a weakening field reactor 17 to a resistor 18 thus producing weakening field from the DC series motor 6.

Abstract: PURPOSE: To obtain combustion at optimal condition through spouting air and refluent exhaust from a jet in accordance with an engine load by controlling operation of an air suction valve and an exhaust suction valve connected through to the jet of an air inlet valve according to opening of a throttle valve.  
     CONSTITUTION: When an air inlet valve 13 opens at an intake stroke, a jet 26 also opens to a combustion chamber 4 simultaneously, and a sucked negative pressure works on an air flow port 56 of an air suction valve 36 and an exhaust flow port 57 of exhaust suction valve 37 through the jet 26, auxiliary intake passage 27 and a passage 58. In this case, a sucked negative pressure in a main intake passage 20a is introduced into negative pressure chambers 40, 47 for the valves 36, 37. Where the sucked negative pressure gets small in accordance as an engine load increases and an exhaust gas pressure working on a valve disc 49 gets large in accordance as the load increases, the valve 36 first opens at a low load to introduce the air into the combustion chamber 4, and next the valve 37 opens at a medium load to introduce the exhaust gas into the combustion chamber 4, thus giving an optimal combustion.

IPC: G07D7/00
Filed: 1987-06-30
Abstract: PURPOSE: To discriminate whether a certain paper money of which damage has been repaired with a transparent adhesive tape, or not by finding the ratio of output from a photodetector at the time of inserting and installing a polarizer in the preceding step of this photodetector in respect to the output of the photodetector at the time of neither inserting nor installing polarizer in the preceding step of the photodetector. CONSTITUTION: The ratio of output from a photodetector 6 at the time of inserting a polarizer 5 before the photodetector to the output of the photodetector 6 at the time of inserting no polarizer 5, at the time of reflection on the front face of a transparent adhesive tape 2 in the case of a repaired paper money 1, becomes the rate of polarizer vibration direction component in reflected polarization in respect to sully reflected polarization, but at the time of reflection on the surface of non-repaired paper money 1, this ratio becomes the rate of polarizer vibrating direction component in diffused reflected light in respect to fully diffused reflected light. Namely, the former ratio is extremely higher than the latter ratio.  Therefore, the ratio found by a ratio operating part is compared with a prescribed value by a comparator part and when that ratio exceeds this prescribed value, based on it, the paper money is discriminated as a paper money repaired with a transparent adhesive tape.

Filed: 1990-06-21
Abstract: PURPOSE:To increase allowable rotational speed of shaft without sacrifice of dynamic balance or rotational stability by stacking soft magnetic disc components and auxiliary disc components made of Invar alloy randomly around a spindle made of Invar alloy.

Title: Multi-tube type multi-beam projector
Inventor: OONO SATORU
IPC: H04N9/31
Filed: 1983-09-06
Abstract: PURPOSE:To obtain a picture plane of high luminance with no deterioration in picture quality by making the space between two electron beams of a CRT containing a fluorescent substance having early luminance saturation longer than the space equivalent to the afterglow time of the fluorescent substance. CONSTITUTION:The space between electron beams Bm1 and Bm2 of a CRT is set longer than the space equivalent to the afterglow time of a fluorescent substance in order to prevent the early luminance saturation on the fluorescent surface of a CRT1B. Therefore a 2H delay line 31 is inserted to shift the space between beams Bm1 and Bm2 in the vertical direction by a (1/2+2) scan line space. While the space between electron beams of CRT1R and 1G is shifted by 1/2 scan line space. As a result, the luminance saturation is delayed to obtain a picture plane of high luminance. No deterioration is produced to the picture quality since no shift is given to the focus. In such a way, a picture plane of high luminance can be obtained with no deterioration in picture quality.

Title: Sealed relay
Inventor: HAYASHI TOMOYOSHI
IPC: H01H49/00
Filed: 1989-06-26
Abstract: PURPOSE:To make it possible to perform ultrasonic cleaning and also stable opening/closing in such a contact as being made of gold by forming, in a housing, a thin wall part having an internal projection made of shape memory resin, and depending on the deformation of the projection under the heat generated on soldering, displacing the movable part of an electromagnetic block so as to hold it apart from a movable contact for performing ultrasonic cleaning in such a state followed by aging action. CONSTITUTION:A thin wall part 12 provided with an internal projection 20a made of shape memory resin is formed in a housing. The projection 20a is deformed by the heat generated on soldering so that a movable part of an electromagnetic block is displaced to hold a movable contact 9a apart from fixed contacts 7a, 7b for performing ultrasonic cleaning in such a state. Thereby, no adhesion is generated on such a contact as being made of gold. When the movable part returns from adhesion by performing aging action after ultrasonic cleaning, it collides with the deformed projection so that the thin wall part around the projection breaks off. Therefore, heated air collected inside a relay is emitted outside.
