Title: Positioning device for stop position of moving plate of mold
Inventor: KURODA NORIKAZU
IPC: B29C45/80
Filed: 1987-03-31
Abstract: PURPOSE:To exactly determine the stop position of a moving plate in response to the kind of a mold by a method wherein the direction and amount of movement of the moving plate is drivingly controlled on the basis of discriminant pattern. CONSTITUTION:When a detected value Li of a positional detector 8 reaches the sum of the mold thickness data set by a mold thickness data setter 9 and a mold carrying-in gap (alpha), a control device 7 issues a moving plate stop position signal in order to put on oil pressure apparatus for driving a moving plate 3 into actuation. Now, after mold thickness data T1 are changed, when L1=T1+alpha is realized, since the stop position is equal to the aimed-at value, the moving plate 3 does not move. When L2<T2 is realized, once molds are opened until Li=T2+alpha+beta is satisfied and, after that the molds are automatically closed and their closing action is stopped by stopping the driving control of the action when Li=T2+alpha is satisfied in the direction of mold closing. When L3>>T3+alpha is realized, the positioning of the moving plate 3 is brought to an end when Li=T3+alpha is satisfied. When L4>T4+alpha is realized, and at the same time the difference between L4 and T4+alpha is small, once the molds are opened until Li=T4+alpha+beta is satisfied and, after that, the molds are closed and stopped, when Li=T4+alpha is satisfied.

Title: See-through plate provided with anti-glare function
Inventor: OTANI YOICHI
IPC: G01D11/26
Filed: 1989-03-30
Abstract: PURPOSE:To easily form a light absorbing film and to prevent a rising film surface from shining and images from being superposed by forming the light absorbing film on the surface of a teeth-shaped projecting part and removing a part of the light absorbing film on a see-through surface with a laser beam. CONSTITUTION:The back surface side of a see-through plate 1 is formed to be a flat surface 2. On the surface side thereof, the fine teeth-shaped projecting parts 5 consisting of the inclined see-through surface 3 and the rising wall surface 4 are formed in parallel and the light absorbing film 6 is applied to the rising wall surface 4. In the case of forming the light absorbing film 6, the light absorbing film 6 is applied to the entire surface of the see-through plate 1 and the film 6 on the see-through surface 3 is removed by being irradiated with the laser beam 8. Therefore, the working of the light absorbing film 6 is extremely facilitated. The light advancing toward the rising wall surface 4 out of the light beam made incident in the medium of the see-through plate 1 is absorbed in the absorbing film 6 of the wall surface 4, so that the wall surface 4 is kept from shining and also the images are prevented from being viewed in the superposed state.

Title: Suction control of internal-combustion engine
Inventor: TAKIMOTO MASATAMI
IPC: F02B31/00
Filed: 1982-05-11
Abstract: PURPOSE:To compensate variation of a combustion speed due to variation of air fuel ratio of mixture for the purpose of preventing engine output torque from varying due to the same reason by reducing the opening of a control valve in a straight passage in response to increase of the air fuel ratio. CONSTITUTION:Based on a signal generated by an O2 sensor 46 which is mounted in an exhaust manifold 34, the magnitude of electric current fed to rear solenoids 22 and 43 is controlled. When a combustion chamber 2 is supplied with mixture of an air fuel ratio higher than the theoretical one, the current fed to the rear solenoids 22 and 43 is reduced to have a valve element 42 actuated to reduce the opening of a valve port 41 for decreasing the additional quantity of air. The opening of a valve element 17 is thereby reduced, enhancing swirl.

Title: Cache memory
Inventor: AONO FUMIO
IPC: G06F12/08
Filed: 1988-03-31
Abstract: PURPOSE:To improve the memory access performance by executing directly an access to a main storage device without changing the inside of a storage in a cache memory, in case when it is decided that a swapping processing is necessary. CONSTITUTION:An input/output device 3 or a processor 2 generates a store request (b), and a cache memory device 1 reads out an address array 6 by a set address (e) of a request address register 5. Subsequently, whether one of superordinate addresses coincides with a superordinate address (d) of the register 5 or not is compared by an address comparator 7, and a result (h) of comparison is decided by a control part 8. When the result (h) is a cache miss, the control part 8 decides whether a swapping processing for rewriting a block which becomes a purge object at the time of loading a new block to a main storage device 4 is necessary or not. When swapping becomes necessary, swapping is avoided by writing directly data to the device 4. Accordingly, the memory access performance is improved.

Title: Cushion for seat
Inventor: INABA YASUHISA
IPC: B29L31/58
Filed: 1989-03-30
Abstract: PURPOSE:To reduce the fatigue during a long time drive by providing a cushion pad having a hard upper layer so as to give a surface rigidity in order to uniformly distribute the weight of a human body over the cushion pad, thereby preventing any part from being exerted with a locally high seating pressure. CONSTITUTION:A seat cushion 1 comprises a seat part 1a, and bank sections 1b on both sides of the seat part 1a. A cushion pad 3 comprises a lower layer 3a made of a resilient and soft urethane foam material and an upper layer 3b superposed on the lower layer 3a and extended entirely in the longitudinal direction of the seat while having a high surface rigidity. When a person sits on the seat, the seat part 1a is alone lowered by the weight of the human body of the person which does not affect upon the bank sections 1b, substantially. Further, in this case, the seat part 1b is uniformly lowered, and accordingly, it is possible to avoid deeply lowering a hit part alone. The weight of the human body is received by the upper layer 3b of the cushion pad 3, and is uniformly distributed all over the lower layer 3a. Thereby the seat cushion 1 is deformed substantially horizontally, and accordingly, it is possible to obtain a seating stability.

Title: Protective circuit of semiconductor device
Inventor: YAMAMURA TAKESHI
IPC: H02H7/20
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To protect a semiconductor device to which both a positive voltage and a negative voltage can be inputted from an abnormal voltage, when an abnormal voltage is inputted to the semiconductor device. SOLUTION: When an input voltage lies within a positive allowable range, a transistor Q1 is turned on and a transistor Q2 is kept in an off-state. If the input voltage exceeds the positive allowable range, the transistor Q2 in the off-state is turned on by causing a punch-through by the abnormal voltage, and the charge due to the abnormal voltage is bypassed through the transistors Q1 and Q2. In the mean time, when the input voltage lies within a negative allowable range, the transistor Q2 is turned on, and the transistor Q1 is kept in the off-state. If the input voltage exceeds the negative allowable range, the transistor Q1 in the off-state is turned on causing a punch-through by the abnormal voltage, and the charge due to the abnormal voltage is bypassed through the transistors Q1 and Q2.

SOLUTION: Plate bodies 11, 12, 13 are laminated to form a plate-like lid 1. A cam plate storage part 111 is cut in the plate body 11, and a movable rod storage part 121 is cut in the plate body 12 so as to form a storage part 10 of a lock key formed of a cam plate 2 and a driven rod 3. The upper face side of the cam plate storage part 111 corresponds to an operating opening for rotating the cam plate 2. A metal plate 4 is fixed onto the operating opening so that the cam plate 2 does not fall off. A handle is fitted to the cam plate 2 and rotated, and the rotary motion of the cam plate 2 is transmitted to the driven rod 3 to put the driven rod 3 in linear motion and to protude the driven rod 3 from a protruding port. The lock key is not therefore deformed by external force during transportation or use so as to prove no hindrance at the time of locking.
