Title: Hydraulic booster for tandem type master cylinder
Inventor: MIZUSAWA MITSUTOYO
IPC: B60T13/12
Filed: 1983-10-18
Abstract: PURPOSE:To make braking reaction in other systems securable without fail even when trouble happens in one system, by connecting a front piston to a pressure receiving piston at a time when an interval between both these pistons becomes narrowed by a specified value, with a fulcrum shaft keeping up the interval between these pistons in front and in the rear of a master cylinder. CONSTITUTION:When braking is at normal, a pressure receiving piston 44 receives braking hydraulic pressure inside a rear hydraulic chamber 82 as operating reaction in a rear piston 72 and compresses an elastic piston 43. Part of this compression force is transmitted to a brake pedal 28 via a reaction piston 45 and a valve piston 26. And, in case of braking at a time when a circuit at the side of a front hydraulic chamber 81 goes something wrong, braking hydraulic pressure is generated in the rear hydraulic chamber 82 alone. Reaction by this hydraulic pressure, like in time of normal, is transmitted to the pedal 28. Likewise, in case of braking at a time when a circuit at the side of a rear hydraulic chamber 82 gets out of order, the rear piston 72 goes forward, and a fulcrum shaft 17 of an interval keeping device 14 hits a front piston 71 whereby the braking hydraulic pressure is generated in the front hydraulic chamber 81 alone. Reaction in this hydraulic pressure is transmitted to the pedal 28 via the fulcrum shaft 17.

Title: Inverter device
Inventor: SATO KATSUMI
IPC: H02M7/537
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To provide an inverter device that prevents an excessive short-circuit current from flowing in an inverter part when restarting the inverter device. SOLUTION: A forced turn-off drive circuit 6 is provided that forcibly turns off a first switching element Q1, if a first drive circuit 3 causes the 'on' state of the first switching element Q1 to continue for a given period of time when an abnormality detecting circuit is operated by detecting an abnormal state. If a driving signal outputted from the first drive circuit 3 remains at the H level which turns an inverter device into a stop state, the forced turn-off drive circuit 6 turns off the first switching element Q1 forcibly. As a result, the first and second switching elements Q1, Q2 are never turned on at the same time, which prevents an excessive current from flowing in the elements.  This structure also prevents the deterioration of the performance of the first and second switching elements Q1, Q2 and the occurrence of failures including a puncture, thereby making it possible to provide a highly reliable inverter device.

Title: Armature assembly structure for motor in power tool
Inventor: SANO YUKIO
IPC: H02K7/14
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To obtain a high-quality rotating shaft, without performing any strict dimensional management and to secure the strength of the shaft by constituting the shaft of a stepped shaft, composed of a large-diameter section and a small-diameter section and forming a gear in the large-diameter section and, at the same time, providing a thrust bearing at the boundary between the large- and small-diameter sections. SOLUTION: An armature assembly is constituted by using a stepped-rotating shaft 2, composed of a large-diameter section 2A having an outside diameter D1 and a small-diameter section 2B, having another outside diameter D2 (D1>D2). On the shaft 2, in addition, a female screw 2C is formed in the large-diameter section 2A, so that an appropriate transmission gear can be meshed with the screw 2C. Moreover, a washer 3 which becomes a thrust bearing is slid on the small-diameter section 2B, until the washer 3 comes into contact with the step section D of the shaft 2. Therefore, no strict dimensional management is required for press-fitting the gear, and at the same time, a prescribed shaft strength is obtained, even when the overall size of the armature assembly is not enlarged.  In addition, the cost of the armature assembly can be reduced, because no after-treatment, etc., is required after performing the press-fitting work.

Title: Fixing method for solid state image pickup element
Inventor: MORII YOSHIHIRO
IPC: H01L27/14
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To shorten the tact time by dividing a process without causing the slippage of the fixing position of a solid state image pickup element that is caused by the softening of an adhesive when the image pickup element and an image forming lens are fixed. SOLUTION: The positions of a CCD 1 soldered on a substrate 5 and an image forming lens 3 attached to a fixing member main body 10 are controlled in a prescribed procedure and according to the magnification. Then the projecting part 19 of the main body 10 is put into the hole of an auxiliary member 6 and fixed there by an ultraviolet ray hardening type adhesive. That is, an adhesion unit 42 is driven to apply the adhesive at the fixing part, and the adhesive is tentatively irradiated by an ultraviolet irradiation source 44. Then the adhesive is compulsorily cooled down to a prescribed temperature or less to secure the holding force that never causes the position slippage in a carrier mode. At a main adhesion process position, the adhesive is irradiated by the ultraviolet rays and the CCD 1 and the lens 5 are fixed at every set position.  Thus the adhesion process is divided into the tentative and main adhesion processes, so that the tentative adhesion process can be carried out for the next work while the main adhesion process is carried out. As a result, the tact time can be shortened.

Filed: 1987-08-05
Abstract: PURPOSE:To detect a degree of removal of stain of food adhered to a wall surface of a heating chamber and keep the stain removed within a required period of time by a method wherein a humidity of a discharging passage containing oxidizing catalyst is detected by a humidity sensor. CONSTITUTION:A heating chamber 1 is heated up to various cooking temperatures with an electrical heater 2. When a stain 6 adhered to a wall surface of the heating chamber is to be removed, it is heated up to 450-500 deg.C. A discharging passage 3 is provided with an oxidizing catalyst 4 and a humidity sensor 5 is installed behind the oxidizing catalyst 4. When a smoke 7 passes through the oxidizing catalyst 4, a complete combustion is carried out through the oxidizing catalyst 4. At this time, a certain humidity is generated, so that atmosphere in the discharging passage 3 containing the oxidizing catalyst 4 becomes a condition in which a humidity is increased. When humidity of the atmosphere within the discharging passage 3 is detected by a humidity sensor 5, it is possible to detect easily whether or not a stain 6 of food adhered to a wall surface of the heating chamber 1 could be removed. So, it is sufficient to keep the heating chamber 1 for a period for the above-described temperature and so the stain 6 can be kept removed for a required period of time without consuming any useless energy.

Abstract: PURPOSE:To prevent the malfunction due to interference light from occurring by discriminating the level of the output anlaog signal of a light receiving element by plural comparators, and varying the oscillation period of a projecting pulse in multiple stages based on those comparison output. CONSTITUTION:The comparators 20, 21, and 22 generate the comparison output Q0, Q1, and Q2, respectively when a detection signal A exceeds threshold voltages V0, V1, and V2. They are held with hold circuits 25-27 controlled by the pulse signal P of an oscillation circuit 51. Transistors(Tr) 31-34 comprising an oscillation control circuit 30 perform switching operation. In other words, when a signal CQ0 from the hold circuit 25 goes to an L level, the transistor Tr32 is turned on, which short-circuits diodes 35 and 36. Similarly, transistors Tr33, Tr34 are turned on by signals CQ1, CQ2, and the diodes 35-37, 35-38 are short- circuited. A signal S turns on the transistor Tr31 with an ordinary L level, and charges a capacitor 40. When the diodes are short-circuited by the signals CQ0-CQ2, charge speed on the capacitor 40 can be accelerated. which shortens the period of the oscillation pulse P.
