Title: Semiconductor laser device and manufacture thereof
Inventor: ISHIKAWA MASAYUKI
IPC: H01S5/042
Filed: 1988-12-14
Abstract: PURPOSE:To increase the maximum optical output of a laser device by a method wherein the band gap of an active layer region under an n-type semiconductor layer region is made larger than that of the other active layer region. CONSTITUTION:A part 14b of an active layer 14 just under an n-type semiconductor layer is formed into a high energy gap region whose band gap is larger than that of a part 14a of the active layer 14 just under a stripe-like opening 17a. The band gap energy of a light projecting end face of the active layer 14 is made larger than that of a primary light emitting section of the active layer 14, whereby light rays are prevented from being absorbed near the light projecting end face of the active layer 14 and consequently the maximum optical output of a laser device of this design can be increased in a continuous operation.

Title: Microcapsule for pressure sensitive recording sheet
Inventor: SANO MASAJIRO
IPC: B01J13/18
Filed: 1988-12-14
Abstract: PURPOSE:To obtain a microcapsule for pressure sensitive recording sheet with high color development and pressure resistance by using a polyurethane uric resin wall as a microcapsule wall and limiting the particle diameter distribution of the microcapsule to a specific range. CONSTITUTION:The microcapsule of polyurethane uric resin wall is obtained by dissolving multivalent isocyanate and multivalent hydroxy compounds and a color developer in hydrophobic liquid, dispersing the dissolved liquid in hydrophilic liquid by emulsification, then adding multivalent amine and coating the polyurethane uric resin with hydrophobic liquid droplets. The particle diameter distribution of the microcapsule is 4.0mu<=D50<=12.0muD90/D10<=2.0, where D10, D50 and D90 are percent particle diameters obtained by cumulative volume distribution, D90/D10 represent how sharp the particle diameter distribution is. The smaller the value of D90/D10 becomes, the sharper particle diameter distribution. The color development and pressure resistance of the microcapsule for pressure sensitive recording sheet are improved proportionately to the degree of sharpness of the particle diameter distribution.

Filed: 1987-12-14
Abstract: PURPOSE:To improve the impact resistance by connecting a cartridge ejection button with a lever tongue and providing a connecting member having an L- shaped tongue to be engaged with a protrusion of a stopper part movable parallel to an upper surface or a lower surface of a holder part. CONSTITUTION:When a stopper 15 is pushed, a lever 14 is to be turned by a spring 18 in its force, but it is not turned due to the engagement between the L-shaped protrusion 17 of the holder 2A and the lever tongue 14a, so that the cartridge ejection button 13 is stopped in its initial position. Furthermore, when the holder 2A is pushed, the stopper 15 is moved backward and then descended vertically, so that the holder 2A is lowered around its fulcrum accordingly, and hence a magnetic cartridge 1 is disposed into a regular position. Then, the lever 14 is turned, and consequently the button 13 is spring out of a front panel by the spring 18 in its force via a tongue 14a and the connecting member 19, and then the L-shaped tongue 19a of the connecting member 19 is engaged with the protrusion part of the stopper 15. By this method, a high impact resistance loading mechanism can be constituted in simple constitution.

Title: Line fault detector
Inventor: NAKAMURA HIDEKI
IPC: H04L27/00
Filed: 1987-12-15
Abstract: PURPOSE:To detect a fault of a radio line due to the presence in an interference wave in real time with simple constitution by detecting the power of an out-band interference and obtaining a ratio of it to a main wave power. CONSTITUTION:The 1st detection circuit 15 is provided with a filter 15a extracting only the center band of a main wave and a detector 15b to detect the power at the center band of the main wave. The 2nd detection circuit 16 detects the power of the entire band of the main wave. A detection circuit 17 obtains an out-band interference power versus main wave power based on the output of the 1st detection circuit 15 and the output of the 2nd detection circuit 16 and gives the result to a terminal 18. In the absence of the interference wave, although the main wave power versus out-band interference power is constant, the ratio is varied by the power of the interference wave when any interference wave exists. Thus, the line fault due to the presence of the interference is detected.

Filed: 1987-12-15
Abstract: PURPOSE:To prevent the degeneration of an input operation and to improve the reliability of an input device by changing the screen of a CRT display in response to the defective light and moving the input area coordinates of a touch panel key. CONSTITUTION:The x-axis and y-axis coordinate optical output detecting circuits 12 and 13 detects the defective beams of both (x) and (y) axes based on the outputs of the x-axis and y-axis photodetection arrays 8 and 10 which defect photo axis scanned on the x-axis and y-axis. A touch panel control part 6 decides whether the detected defective light is included or not within a coordinate range of the touch panel key input based on the coordinate data on both x-axis and y-axis directions obtained by detection of the defective light. If so, the display data is changed by a main control part 2 according to the input area coordinate data on the touch panel key of the part 6. Then the screen of a CRT display 4 is changed via a CRT display control part 5 and therefore the input area coordinate position of the touch panel key is moved. As a result, the degeneration of an optical touch panel input device can be prevented.

Title: Cream solder
Inventor: HARITA YASUHISA
IPC: H05K3/34
Filed: 1987-12-16
Abstract: PURPOSE:To prevent the oxidation of the solder powder surface even on standing, and to suppress the separation of the coated powder with time by coating each solder powder particle with a specified single fatty acid salt. CONSTITUTION:The solder powder is coated with a single fatty acid salt before a flux is mixed so that the content of the salt is controlled to 0.8-1.2wt.%. The other flux is added to the powder, and kneaded to form cream solder. The cream solder is applied on a base 1 by screen printing and a dispenser. Since the solder powder 3 is coated with the single fatty acid salt 5 as the solder powder 6, the surface of the solder powder 6 is not oxidized even after the powder is allowed to stand for about 24hr, and the generation of solder balls can be prevented when the solder is melted.

Title: Narrow band interference wave limiting device and communication device using the limiting device

IPC: H04B1/707
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a narrow band interference wave limiting device capable of reducing degradation in the quality of a diffusion signal due to entrainment despite of using a magnetostatic wave filter. SOLUTION: A signal of a 1st signal route p1 limiting the level of a narrow band interference wave only by 2 to 6dB through a limiter type magnetostatic wave filter 13 and a signal of a 2nd signal route p2 attenuated so that the level of the narrow band interference wave becomes the same as that of the 1st signal route p1 are mutually synthesized so that their phases are reversed to each other. In the synthesis, respective narrow band interference waves are mutually canceled and limited. Since the level limitation quantity of a narrow band interference wave by the magnetostatic wave filter is less, the deterioration of a diffusion signal due to entrainment can be reduced.
