Title: Semiconductor laser device
Inventor: WAKANA SHINICHI
IPC: H01S5/10
Filed: 1985-11-19
Abstract: PURPOSE:To obtain a required polarization mode by a small apparatus which is easy to assemble by a method wherein a structural anisotropic medium, composed of alternately laminated media with different specific inductive capacities, is provided at the emitting end surface or in the waveguide region of a semiconductor laser. CONSTITUTION:A structural anisotropic medium 7 is formed by arranging medium 1 and medium 2 which have specific inductive capacities different from each other alternately at the emitting end surface of or inside a semiconductor laser (LD). The boundary surfaces 8 between the media 1 and 2 are inclined to have an angle of 45 deg. relative to the junction surface of the LD. With this constitution, the laser oscillation is induced by using the boundary surface between the LD and the medium 7 as a reflective surface of a resonator and the output light is oscillated with a polarization mode which is determined by the thickness T of the medium 7, the widths t1 and t2 of the media 1 and 2. Therefore, by selecting those parameters, a required polarization mode can be obtained and an optical system can be assembled easily in a small size. Moreover, by providing the media 7 on both ends of the LD, clockwise or counterclockwise circular polarization can be obtained.

Filed: 1994-10-25
Abstract: PURPOSE: To avoid impairment to sealability by a method wherein either of notching forming dies is provided with a needle for piercing an air escaping hole in the film at the mating part of the notching forming dies before their mutual engagement. CONSTITUTION: A through hole 35 is formed in a lower sealer 21 as a female die 42 for receiving a male die 41 and a bearing member 38 is inserted into the through hole 35. The bearing member 38 is smaller in inside diameter than a circular cutting edge 32 of the male die 41 and is provided with a reduced part 36 of a predetermined thickness. An enlarged part 37 the same in diameter as the through hole 35 is provided under the reduced part 36 with the raised cross sectional area. The bearing member 38 with such a raised cross sectional area is provided in its center with an upright needle 39 for piercing an air escaping hole in a cylindrical film.  In this way the air accumulated in the cylindrical film is allowed to escape from the air escaping hole to outside instead of escaping sideways between the joined films, thereby avoiding impairment to the sealability of the interior of a package.

The signal of a paper splicing command starts the measurement of the rotational frequency to obtain the overrun length after paper splicing. After the stop of the rotation, a press roller 6 presses the peripheral surface of the roll 10 to drive a rewinding motor 4. The amount of rewound paper is computed from the rotational frequency, and the motor 4 is controlled to its lowest speed when the paper feeding reaches a given value or below. A device for sticking tapes 7 contacts the peripheral surface of the roll 10 and is actuated by the signal of a paper end detector 5.

Title: Map-data transmission system
Inventor: SATO KENYA
IPC: G01C21/00
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To transmit map data to a vehicle at an accurate timing even when a data transmission rate is low by a method wherein the map data at the front in the advance direction of the vehicle is acquired in advance and retained by an on-vehicle apparatus. SOLUTION: A radio telephone 2f is connected to a control part 3b at an on-vehicle apparatus 2 through a modem 2e, and map data is exchanged between the on-vehicle apparatus and a center apparatus 1. The control part 3b transits data on the present position of a vehicle and on its advance direction to the center apparatus 1 and requests map data. The center apparatus 1 retrieves map data on an estimated position at the front in the advance direction of the vehicle and transmits the retrieved map data to the vehicle. In the on-vehicle apparatus 2, the transmitted map data is stored temporarily in a memory 3c for prefetch, and it is then displayed on a display when the vehicle is going out of position on a map which is displayed at present.  In this manner, the map data, on the advance direction, which is acquired in advance so as to be stored can be displayed immediately when the vehicle enters its region.

IPC: G03G15/047
Filed: 1986-10-31
Abstract: PURPOSE:To enable composition without image overlapping by erasing an area wider than a specified area corresponding to masking and leaving an area narrower than the specified area corresponding to trimming. CONSTITUTION:When the desired area on an original is specified by a tablet input part, a control part 27 calculates the number of LEDs 16a to be turned on in an eraser consisting of an LED array facing a photosensitive body and illumination continuance from a coordinate signal. Then when masking or trim ming is selected, one LED16a each corresponding to the Y coordinate is added to both sides and turned on or off, and the turn-on or -off continuation is in creased by one pulse of a rotary encoder as compared with a time corresponding to the X coordinate. Therefore, an area to be erased at the time of the masking or left at the time of the trimming is set smaller and the composition is carried out without image overlapping.

Title: Pulley structure, cable laying unit, and vertical laying method
Inventor: HIDAKA AKIRA
IPC: H02G1/06
Filed: 1993-10-19
Abstract: PURPOSE:To restrain increase of hauling load even at a curved part of cable laying path while preventing entanglement of a master wire and a cable by cutting one of the opposite side walls at the groove of a rotatable pulley where the a linear material being guided is engaged. CONSTITUTION:When a branch wire 38 passes through a pulley 32 while being pulled by a master wire 26, a conical leading piece 44 principally comes into contact with the high wall 32B side of an engaging groove 33A and shifted, at the rear end part thereof, to the low wall 32C side. Upon engagement with the pulley 32, a separation piece 42 falls off from the pulley 32 due to the weight thereof thus allowing separation of the master wire from the cable 20. Even when the master wire 26 moves perpendicularly to the moving direction of the separation piece 42, the separation piece 42 makes a smooth switching to the moving direction of the master wire 26 and leaves the low wall 32C side of the groove 32A in the pulley 32. Consequently, the master wire is guided by forming a cable laying path while simultaneously it is separated from the cable.

Abstract: PURPOSE:To enhance the workability by detecting an output signal from a photocoupler at each elapse of prescribed time and restoring a tray mounted with a disk completed for reproduction to the storage position from which the tray is extracted. CONSTITUTION:A distance of a support 4 moved for a prescribed time is made constant and an output signal from the photocoupler 41 is detected at each prescribed time of elapse. Thus, an unoccupied storage position of a storage section 52 is detected attended with the movement of the support 4. Thus, the detector detecting the presence of each tray is not provided to each storage position of the storage section 52 and after a CD disk is reproduced, the CD disk is restored to the storage section together with the tray. Moreover, the presence of the tray at each storage position of the storage section is executed by measuring the time to restore the disk extracted from the storage section before application of power.
