Title: Children's seat
Inventor: TAMURA KEIICHI
IPC: B60R21/207
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To enhance protecting performance for children at the time when high prescribed loading is applied to a car body. SOLUTION: An air bag device 44 is disposed in the inside of the seat cushion part 12 of a children's seat, which is formed out of paired inflators 46 to be actuated for injecting gas at the time when prescribed high loading is applied, and of a bag 48 disposed around the inflators 46 in a state that it is folded. Therefore, when prescribed high loading is applied, the bag 48 is expanded by means of gas injected out of the inflators 46 so as to allow bag side parts 48B that are parts of the bag, to be swollen to the sides of the children's seat 10. By this constitution, protecting performance for children can thereby be enhanced at the time of prescribed high loading applied.

Title: Method for molding hub for optical disk
Inventor: FUKUSHIMA ISAMU
IPC: G11B7/24097
Filed: 1993-12-21
Abstract: PURPOSE:To effectively prevent deformation and generation of crack occurring in stress and strain at the time of cooling after molding by applying compressive force to a hub in its thickness direction before a molten resin cools and solidifies in the cavity formed by metal molds. CONSTITUTION:The molten resin 10 is injected and packed into the cavity 10 by the stationary metal mold and the compressable metal mold 1 to injection mold the hub for an optical disk. The compressive force is applied to the resin 10 in the thickness direction of the hub via the metal mold 11 before the resin cools and solidifies. As a result, the deformation of the hub, generation of crack and generation of whiskers which arise from the difference in thermal expansion rates between the synthetic resin and the magnetic material at the time of cooling after molding are effectively prevented.

Title: Optical switch
Inventor: FUKUMA MASUMI
IPC: G02B26/08
Filed: 1990-11-26
Abstract: PURPOSE:To improve durability without damaging the switching performance of the optical path by providing to an abutting surface of the other switch element a discontinuous part where the end surface part of a fiber array and the end surface part of both positioning grooves may be discontinuously. CONSTITUTION:When the second switch element 3 is shifted from the stationary position to the switching position while the first switch element 3 is fixed, then a positioning pin 4 is shifted from the engaged condition with the first positioning groove 9a to the engaged condition with the second positioning groove 9b, and the optical path is switched. This switching shift of a switch element 2 allows the friction between the positioning pin 4 and both positioning grooves 9a, 9b to be decreased by the lubricant in the positioning grooves, leading to improvement of durability. And if the lubricant flows out of the positioning grooves at the abutting end surface of the switch element 2, a discontinuous part 13 between an end surface 6a of the fiber array 5 and the end surface part 6b of both positioning grooves prevents the flow of the lubricant, and the lubricant does not flow up to the end surface of the fiber array 5. This constitution improves the connection properties.

Title: Electric jar pot
Inventor: KONNO SETSUZOU
IPC: A47J27/21
Filed: 1987-12-18
Abstract: PURPOSE: To enable to automatically stop hot water delivery action even in a failure of a switch mounted series in the power source circuit of a hot water delivery pump motor to be in a conducting condition, by constituting an electric jar pot to check the existence of hot water delivery instruction to open a second switch when a hot water delivery detecting means detects hot water delivery. CONSTITUTION: When first and second terminals of a bidirectional thyristor 7 are short circuited, this electric jar pot tries to deliver hot water even though it is not set in a hot water delivery mode, but, in this case, hot water delivery is stopped when hot water delivering is detected. Power supply to a hot water delivery pump motor 6 is cut by conducting power to a relay 18 to open a normally-closed contact 19. Normally, this condition is kept continuously until power supply from a commercial power source is turned OFF. Since a second normally-open contact 19 comes in open condition when the bidirectional thyristor 7 as a first switch came in failure like that, a place where the electric jar pot is set is prevented from getting wet by hot water and a user in the vicinity of the hot water delivery port is prevented from an accident of getting burnt.

Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory element from which data can be read out at a high speed by reducing the input offset of a sense amplifier at an arbitrary point of time by incorporating a trimming device in the sense amplifier. SOLUTION: A semiconductor memory element M is provided with a memory cell 2, decoders 3 (row) and 4 (column), a sense amplifier 5, and a trimming device 8 and the amplifier 5 is constituted of a driver 6 and trimming blocks 7. When the trimming device 8 is constituted of a fuse array circuit, two control input signals are supplied as the output of the fuse array circuit. When the measured optimum trimming adjusting value of a certain sense amplifier is, for example, 15mV, the fuses of output circuits to first and second trimming blocks TRM 1 and TRM 2 do not blow off and and the output circuits are set to conducted states. Therefore, only the input offset of the sense amplifier becomes the minimum of 5mV, because both the two control inputs are outputted.

Title: Optical deflecting element and method
Inventor: ATSUMI HIROMICHI
IPC: G02B26/10
Filed: 1990-11-27
Abstract: PURPOSE:To enhance the efficiency of optical scanning while effectively utilizing the advantages of a pyramidal mirror by providing a half mirror surface which inclines at 45 deg. with the axis of rotation and a mirror surface intersecting orthogonally therewith so that an incident luminous flux is first made incident on the half mirror surface and the transmitted luminous flux is made incident on the mirror surface. CONSTITUTION:The incident luminous flux is made incident by aligning its main beam to the axis 8 of rotation of the optical deflecting element 3, is bisected by the half mirror surface 31 and is partly reflected. The rest transmits the mirror surface 31. Since the half mirror surface 31 inclines at 45 deg. to the axis 8 of rotation, the reflected luminous flux emits in the direction orthogonal to the axis 8 of rotation and is deflected within the plane orthogonal to the axis 8 of rotation as the optical deflecting element 3 rotates. On the other hand, the luminous flux transmitted through the half mirror surface 31 is reflected by the orthogonally intersecting half mirror surface 31 and is again made incident on the half mirror surface 31. The reflected luminous flux is emitted in the direction orthogonal to the axis 8 of rotation. Then, the two luminous fluxes facing reverse from each other are deflected within the plane orthogonal to the axis 8 of rotation. The efficiency of the optical scanning is improved while the advantages of the pyramidal mirror are effectively utilized.

Abstract: PURPOSE:To reduce the dispersion of a constant voltage output voltage even if a driving current is increased by inserting a level shifting PNP transistor(TR) into the power supply circuit. CONSTITUTION:A transistor 5 and a resistor 15 are added to constitute the power supply circuit. Namely, the collector of a TR 2 is connected to the collector of a TR 4 and the base of a TR 5 and the emitter of the TR 2 is connected to a power supply Vcc through a resistor 12. The collector of the TR 5 is connected to a reference potential and the emitter of the TR 5 is connected to the power supply Vcc through a resistor 15. The base, collector and emitter of a TR 6 are respectively connected to the emitter of the TR 5, the power supply Vcc and the base of a TR 7 through a resistor 16. Since the increment of a base current IBQ6 appears as 1/hFEQ5 on the base current IBQ5 of the TR 5 even if the driving current of a constant voltage output is increased, a current ratio P1 can be obtained and the dispersion of the constant voltage output voltage Vref can be reduced.
