Title: Semiconductor light-emitting device
Inventor: KATSUKI YOICHIRO
IPC: H01S5/022
Filed: 1985-05-20
Abstract: PURPOSE:To provide a compact and inexpensive semiconductor light-emitting device which can couple light emitted from an LD chip with a light-receiving element and which has a high reliability, by providing an opening in a stem for taking out light emitted from the LD chip and disposing a spherical lens in this opening. CONSTITUTION:A cap, which is provided with a window for taking out light emitted from the upper end face of an LD chip 12 so as to use the light for a signal, is attached to a stem 11. The stem 11 is provided with an opening for taking out emitted light so as to use the light for control, and a spherical lens 15 is fixed in the opening with a brazing material in a hermetically sealed manner. The spherical lens 15 is fixed at a predetermined distance from the end face of the LD chip, and the distance is previously calculated such that the lens can focus the light on and couple the light to a light-emitting element 14. Thus, since the section for mounting the LD chip 12 and the opening for taking out emitted light for control are provided integrally in the stem 11 with a high precision, the LD chip 12 as well as the spherical lens 15 can be positioned accurately.

Title: Vibration damper installed to structure
Inventor: MAEDA TOSHIAKI
IPC: F16F15/02
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To obtain damping force simply by dispersely installing a plurality of wind mill type gyro devices at the top section of a multi-story structure and generating a damping force by rotating the bodies of the gyro devices around the vertical shafts of the revolution bodies by wind force. SOLUTION: When a wind works to a multi-story structure 1, bending deformation by wind vibrations exceeds at the top section of the structure 1 and rotational deformation is generated. Wind mill type gyro devices 2 directly receive wind force at that time and moment resisting the rotation of the base sections of the vertical shafts 5 of the device 1 is generated, and the rotational deformation of the structure 1 is offset and erased by the moment. The gyro devices 2 directly detect wind force in the arbitrary direction instantaneously while the bodies of revolution 3 are turned around the vertical shafts 4 and damping force is generated. Consequently, the generation of damping force against wind force is not delayed, and a damping effect is improved with an increase in wind force. Accordingly, vibrations due to the wind of the structure can be inhibited quickly.

Title: Member for bonding together copper material and aluminum material and manufacture thereof
Inventor: NOGUCHI MASATAKA
IPC: B23K103/12
Filed: 1991-04-10
Abstract: PURPOSE:To perform easy and reliable bonding of copper to an aluminum material and to reduce a bonding cost by removing the given region of a cladding material to expose a core. CONSTITUTION:A covering material 3 on the one end part side of a cladding material prepared such that an aluminum core 2 and a copper covering material 3 are metallically bonded together is cut for removal to expose the core 2. When a copper material and an aluminum material are bonded together by using a bonding member 1, the bonding member 1 and the aluminum material are bonded together at a region, where the core 2 is exposed, by, for example, welding. In a region covered with a covering material, the bonding material 1 and the copper material are joined together through mechanical fastening by means of, for example, bolt and nut. In this case, since the same kind of metals are bonded to each other, a bonding strength is high and there is no need for a device, such as a heating furnace and a hydrostatic extrusion device, and a cost is reduced.

Abstract: PURPOSE:To make the extent of working frequency smaller as well as to make improvements in durability by setting a car speed, changing high arm pressure over to low arm pressure, to be lower than that changing the lower arm pressure over to the high arm one. CONSTITUTION:A pulse being generated out of a reed switch 11 corresponding to a car speed is converted by an F/V converter circuit 12, and compared by each of comparators 15, 16 on the basis of a reference voltage being inputted from respective terminals 13, 14, operating a motor driving control circuit 20, and pressing force (wiper pressure) of a wiper blade to a glass surface is altered. The car speed, changing high arm pressure over to low arm pressure, is set to be lower than that changing the low arm pressure over to the high arm pressure. Working frequency in an arm pressure changeover is reduced, whereby improvement in durability of the whole body of an arm pressure adjusting system is thus promotable.

Title: Flip-flop ic
Inventor: SHIMADA TETSUHIRO
IPC: H03K3/037
Filed: 1989-04-26
Abstract: PURPOSE:To easily and efficiently compensate a minimum delay time of other circuit and an 10 or the like by retarding an output of a function section having a function of a FF by a different time and outputting the result externally from an output terminal. CONSTITUTION:A delay time of a scan circuit such as an FF circuit is calculated in the stage of design. When a delay time for one period is less than a minimum delay time required for the design, the minimum delay time compensation is required. In this case, an output terminal 109 is used to add the delay by an internal delay circuit 2 and the minimum delay time is compensated. On the other hand, when the delay for one period satisfies the minimum delay time, an output terminal 109 is used to compensate the minimum delay time without adding the delay by the delay circuit. Thus, when the output terminal 108 or 109 is used alternatively, the minimum delay time required for the design is compensated.

Filed: 1987-04-30
Abstract: PURPOSE:To access an optional position in a region only with a relative address by setting a base address which specifies the region in the address space of a processor in a page register. CONSTITUTION:When the control processor 32 accesses the window 72 of the image memory address space 71, the processor makes an instruction so that the leading address AB of the window 72 is set in the base address register 50 as the base address. The control processor 32 performs the base address setting processing and then transfers the address AM of the optional position in the region 62 arranged in its address space 61 to a bus conversion adapter 35. A control part 47 decodes the high-order part of an address transferred from an image processor 31 and allows a bus interface 44 to perform output operation. Consequently, the A address of the memory of the image processor 31 is accessed.

Title: Train wheel structure for analog time piece
Inventor: TAKEDA KIYOTO
IPC: G04B13/02
Filed: 1991-05-13
Abstract: PURPOSE:To prevent the play of indication hand at the indication point toward the rotation direction and eliminate the shift against the scale on the face by forming the shaft of wheel piecess in a train wheel with a rubber type resin material, and eliminating the backlash of teeth for transmitting engage of the train wheel. CONSTITUTION:The backlash in teeth engage between fifth wheel 4b and fourth wheel 5 is determined so that the distance between support shafts rules null backlash when the torelance of support shafts of the wheel 4 and the wheel 5 is positive. Conversely, when the torelance of the support shafts is negative, the support shaft 4c (formed with an elastomer material of rubber type resin) of the wheel 4 is pressed by the wheel 5 to be displaced elastically. To avoid this, the load at the teeth tip during engaging is reduced and stop is avoided. The roter 3 and the wheel 5 are arranged to be at an angle approximately 90 degrees putting the wheel 4 in between. Thus, this train wheel structure avoids the pressure of gear part of the wheel 4 on the roter 3.
