Title: Four way switch device
Inventor: KITAWAKI HIROYASU
IPC: H01H25/04
Filed: 1994-12-12
Abstract: PURPOSE: To provide a compact four way switch device. CONSTITUTION: A rotation body 7 is arranged rotatively in a cases 1 and 2, four actuators 41 to 44 are provided between a push plate 3 and the rotation body 7, and the rotation body is provided with four sets of tilt surfaces 71 to 74. A protrusion 410 of the four actuators 41 to 44 and four sets of tilt surfaces 71 to 74 have their relative position relationship in which push operation of three parts other than the push plate 3 is restricted when a certain one part of the push plate 3 is push-operated. As a result, when the push plate 3 is push-operated a certain one part, push operation at three parts other than the push plate 3 is restricted. Thus, since an interlock mechanism is made of rotation body 7, etc., arranged rotatively in the cases 1 and 2, a four way switch device can be compactly constituted.

Filed: 1994-11-16
Abstract: PURPOSE: To minimize the number of part items to simplify the assembling, and reduce the cost by providing a light emitting element formed of a laser light source for emitting a parallel light or a spherical wave having a large curvature radius. CONSTITUTION: A light emitting element 1 is formed of a surface emitting laser, and the luminous flux emitted from the element 1 basically forms a parallel light.

Title: Formation of optical disk
Inventor: MATAKE SHIGERU
IPC: G11B7/26
Filed: 1986-12-26
Abstract: PURPOSE:To prevent corrosion of aluminum reflection films and to permit formation of a disk having durability and high reliability by bringing two sheets of disk substrates into tight contact with each other by a vacuum, then welding the circumferential edge of the substrates in a vacuum. CONSTITUTION:Two sheets of the substrates each constituted by forming the aluminum reflection film 13 and a protective film 14 consisting of a synthetic resin on a disk substrate 12 are previously brought into contact with and superposed on each other by the vacuum. The outer circumferential end face and the substrate circumferential edge 15 which is the end face of a central hole for a spindle are then melted and welded in the vacuum. Since the mating part of the substrates 12 is maintained in the vacuum state, the aluminum reflection films 13 are not deteriorated and corroded by the external atmosphere, above all, humidity and temp. Since no adhesive agents are used, the corrosion by impurities incorporated into the adhesive agent is obviated and the durability and high reliability are maintained for a long period of time.

Title: Electrode with hydrogen storage alloy
Inventor: TAKEE MASAO
IPC: H01M4/38
Filed: 1991-11-25
Abstract: PURPOSE:To suppress the drop of the discharge capacity of an electrode including powder of hydrogen storage alloy and enhance the cyclic characteristics by forming a layer of metal carbide in a part of the surfaces of this powder of hydrogen storage alloy. CONSTITUTION:A negative electrode 2 includes a power of hydrogen storage alloy which can reversibly store and release hydrogen as neg. electrode active material. By carburization process, metal carbides are formed on at least part of the surfaces of this powder of hydrogen storage alloy. This enhances the anti-erosiveness of the alloy powder, which suppresses its oxidation due to alkaline electrolytic solution or oxygen gas generated when the battery is over- charged. This allows to suppress the drop of the neg. electrode capacity, so that the cyclic characteristics are enhanced.

Title: Torque detector for synchronous motor
Inventor: TAKAKADO YUZO
IPC: H02P27/08
Filed: 1989-11-30
Abstract: PURPOSE:To detect the generating torque of a synchronous motor correctly with a high reliability without employing any mechanical torque transmitting means by a method wherein the outer product operation of a vector is effected based on the vector of magnetic field flux and the vector of an armature current. CONSTITUTION:A position feedback signal, same as the output of a rotating angle detector 11, is processed to produce the vectors of magnetic field flux PHIdF, PHIqF while the output signals of current detectors 14A, 14B are processed to produce an armature ampare-turn vector. The outer product operations of these vectors are effected by multipliers 18, 19 and the results of the operations are added by an adder 20 to detect a torque T. Accordingly, a mechanical transmitting means so far is not necessary and the generating torque of a synchronous motor is detected directly whereby highly accurate torque detection may be effected. The detecting value is the instantaneous value of a torque and, therefore, the detected value may be used as the feedback value of a high- speed response control system employing the synchronous motor.

Title: Fuel octane value judging device for internal-combustion engine
Inventor: TAKAHASHI NOBUTAKA
IPC: F02P5/152
Filed: 1987-12-07
Abstract: PURPOSE:To facilitate judgement by judging octane value of fuel based on frequency distribution of knocking control as ignition timing control and MBT control (control to bring ignition timing to minimum lead angle position in order to produce maximum torque). CONSTITUTION:When an internal-combustion engine is operated, a peak position detecting means 2 detects peak position of combustion pressure based on an output from a means 1 for detecting combustion pressure, and a knocking detecting means 3 detects existence of knocking. MBT control means 4 is selected when no knocking is detected while a knocking control means 5 is selected when knocking is detected so as to control ignition timing. It is stored sequentially into a memory means 6 whether MBT control is performed or knocking control is performed for operating zones sectioned into plural zones, and an octane value judging means 7 judges octane value of fuel based on frequency distribution of both controls in an operating zone.

Title: Flood control water quality conservation system
Inventor: SHIYOUJI NAGAHIRO
IPC: E02B3/00
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To usefully promote settling operation of earth and sand in a regulating reservoir. SOLUTION: A flood control water quality conservation system is so constituted that water from an inflow channel Q is detoured to a regulating reservoir P to adjust flow rate of the inflow channel Q and, at the same time, that earth and sand in flowing water is settled. Based on detected value of a water turbidimeter 2 in the inflow channel Q, water flowing into the regulating reservoir P is adjusted by a valve V1, and when detected value of a water turbidimeter 3 in the regulating reservoir is below the specific value, water is discharged from the regulating reservoir P. By the constitution, the introduction of flowing water unrequired for making settling operation of low turbidity is not made, and efficient settlement purifying operation can be executed.  When the regulating reservoir P is full of rain for many hours, the difference between flow velocity in the inflow channel Q and flow velocity in the regulating reservoir P is made irrespective of the turbidity in the regulating reservoir P, and water is discharged to the inflow channel Q while settling earth and sand, By the constitution, rain water passing through the regulating reservoir P is discharged to the inflow channel Q by the difference in flow velocity after the settling operation of earth and sand is made more or less, and high turbidity of a river R or the like can be controlled.

Filed: 1989-11-30
Abstract: PURPOSE:To obtain a high withstand voltage between an emitter and a base by separating the emitter layer from the external base layer using an insulating film of a mesa side wall with a small gap. CONSTITUTION:In this bipolar transistor, a region where an inner base layer 15 and an emitter layer 17 are formed is in mesa type 8, a thermal oxide film 9 is formed on the side wall of the mesa 8, and an external base layer 13 is formed at the outside.
