Title: Narrow band laser device
Inventor: SAKUMA JUN
IPC: H01S3/081
Filed: 1988-03-30
Abstract: PURPOSE:To increase laser power transmitted through the exciting volume of a laser oscillation part and increase the output by forming a plurality of transmitting parts in laser beam control members in parallel with the direction of the trenches of diffraction lattices. CONSTITUTION:Control members 12 are provided at both the ends of a laser oscillation part 11 respectively. A plurality of slits 13 are formed in the upper and lower parts of the respective control members 12 in parallel with each other as transmitting parts. The laser beam L transmitted through the upper slit 13 is applied to an enlarging optical system 15 and the laser beam L transmitted through the lower slit 13 is applied to an enlarging optical system 16. Then the laser beams L are enlarged to the direction same as the control direction given by the slits 13 and applied to diffraction lattices 17 and 18 respectively. With this constitution, the number of trenches of the diffraction lattices 17 and 18 to which the respective laser beams L are applied is increased so that the resolution can be improved. Moreover, the inclination angles of the diffraction lattices 17 and 18 are so predetermined as to make the incident angle of the laser beam L and the reflection angle of the diffracted light equal to each other and the laser beams L go back and forth on the same light paths between an output mirror 14 and the diffraction lattices 17 and 18. Therefore, the summation of the outputs of the two laser beams L is about twice the output of one laser beam so that the output can be increased.

Title: Antenna circuit for portable receiver
Inventor: SATO ATSUSHI
IPC: H01Q7/00
Filed: 1990-03-23
Abstract: PURPOSE:To stably obtain receiving sensitivity by setting an antenna circuit as a resonance circuit comprising a loop antenna and a capacitor, and constituting one antenna circuit by coupling two resonance circuits with different resonance frequencies with the capacitor. CONSTITUTION:The frequency of a reception signal received by each of the resonance circuits 13, 16 is selected by the resonance frequency decided by the capacitor 12 and the loop antenna 11. When the loop antenna approaches part of a human body, the resonance frequency of the resonance circuit is changed by electrostatic coupling, and the change quantity of the resonance frequency is changed based on the degree of the above change. Thereby, the resonance frequency of the resonance circuit 13 is adjusted so as to conform to a receiving frequency when loose coupling between the human body and the loop antenna is obtained, and that of the resonance circuit 16 is adjusted so as to conform to the receiving frequency when the loose coupling between the human body and the loop antenna is obtained. In such a way, it is possible to always obtain the receiving sensitivity conformed to the receiving frequency without being affected by a transportation method.

Title: Probe card
Inventor: HATA MASAHARU
IPC: H01L21/66
Filed: 1993-04-01
Abstract: PURPOSE:To reduce the damage of a pad itself which is caused by the needle tip of a probe, by making the needle tip of a probe card a bigger sphere or ellipsoid than the diameter of the probe. CONSTITUTION:In a probe card, each one of probes 2 of the probe card is so formed that when it is contacted with a pad 4 in the chip laid on a wafer, its needle tip is made to be bigger sphere or ellipsoid than the diameter of the probe 2. Therefore, a contact area 5 of the needle tip with the pad 4 is made large, and the pressure per unit area where the needle tip is pressed on the pad 4 is reduced. Thereby, the damage of the pad 4 itself which is caused by the needle point can be reduced. Also, when the needle point is in contact with the pad 4, the probe 2 is bent, and a contact angle theta of the needle tip with the pad 4 is changed. But, since the needle tip is the bigger sphere or ellipsoid than the diameter of the probe 2, regardless of the contact angle theta, the contact area 5 of the needle tip with the pad 4 is made larger than conventional ones, and the probe 2 can be contacted with the pad 4 in a stable state.

CONSTITUTION:At least one metal among Pb, In, Ti, and Bi which do not enter into solid solution is finely dispersed into Al by about 0.5wt.%, by which an Al alloy excellent in machinability can be obtained. In the method for melting the metal, the metal is formed into a sheet of <=0.5mm thickness and, preferably, is formed into small pieces of about 10-300mm major axis and about 5-300mm minor axis. Subsequently, this sheet is covered with a metal foil having a melting point higher than that of the sheet but capable of melting in molten Al. As the metal foil, Al foil, Cu foil, Zn foil, etc., can be used and suitable thickness of covering is about 0.015-0.2mm. Then the resulting covered material is added into molten Al and melted by agitation. By this method, the metal can be uniformly dispersed into Al to an average grain size about one-tenth the thickness of the sheet.

Filed: 1990-03-27
Abstract: PURPOSE:To dry ink properly by disposing an ink drying means in the vicinity of a recording head and providing a control means for controlling said ink drying means on the basis of the detection result of a temperature detection means. CONSTITUTION:After the start of a recording action, an analog signal representing the detection result of a temperature sensor 12a mounted on a recording head is converted to a digital signal by an A/D converter 13a.

Title: Limit detector of horizontally moving object
Inventor: TANOKURA SHINICHI
IPC: G01B21/00
Filed: 1990-03-26
Abstract: PURPOSE:To reduce the size of a detector and simplify its use by providing the detector with a contact portion in contact with a separating member for separating a limit region, an extension piece mounted on a movable member as extended from it and a sensor for detecting the displacement of the extension piece. CONSTITUTION:When an X-Y table horizontally moves and a limit ring is brought into contact with a contact portion 26, a movable member 23 moves against a balance ring 19. Therefore, a light shielding portion 30 also moves integrally with the movable member 23 and light irradiated from a first sensor 14 is shielded by a light shielding portion 30. Thus, a signal is outputted from the first sensor 14 and the next pitch feed of the X-Y table can be disabled. Further, when the limit ring is brought into strong contact with the contact portion 26, also a second hole moves with respect to a second sensor 15 and light irradiated from it is shielded by the light shielding portion. Thus, a signal is outputted from the second sensor 15 and used as an emergency signal to stop an X motor and a Y motor or used as a power supply off signal.

Title: Optical information recording medium
Inventor: KOBAYASHI TERUO
IPC: G11B7/2433
Filed: 1984-04-16
Abstract: PURPOSE:To record and reproduce information with small light energy by forming a thin recording film of a thin metallic film consisting essentially of Ge, Sn and Te. CONSTITUTION:The thin film of an optical information recording medium is formed of the compsn. G1-xSnxTe (0<x<=0.7) consisting essentially of germanium, tin and tellurium. The non-crystal-crystal transfer point of the thin Ge1-xSnxTe film, as compared with a thin GeTe film, decreases with an increase in the value (x) in the thin Ge1-xSnxTe film; for example, said point is 410 deg.K at x=0.2 and 350 deg.K at x=0.5. The light energy required for recording information is 86% when x=0.2 and 59% when x=0.5, thus the light energy can be economized respectively by 14% and 41% as compared with the thin GeTe film. The reason for specifying the compsn. of the thin Ge1-xSnxTe alloy film at 0<x<=0.7 lies in that the above-mentioned thin film transfers already to crystalline substance at a room temp. when x>0.7 and that recording of information is infeasible in such a state.

Filed: 1986-04-04
Abstract: PURPOSE:To attain the optimum control of an auxiliary memory by forming a control table which decides whether all cache memories are allocated to a system disk or to plural disks in division according to the command received from a host processor. CONSTITUTION:A control processor 3 stores the drive number and the cash size designated by a disk dividing command into a cache division control table 13. Then a cache control table 10 is allocated (10A, 10B) to the respective drives (e.g. disks 7A and 7B) and used as cache memories 5A and 5B corresponding to those drives. These cache memories are controlled by a cache memory control system. Thus the cache memories are all allocated to the system disks until a primary command is received after a power supply is applied.
