Title: Solar heat absorbing object
Inventor: FUJII MASAHARU
IPC: C25D15/02
Filed: 1981-03-20
Abstract: PURPOSE: To improve selective absorption and heat resistance of an obtained solar heat absorbing object, by forming a selective metal oxide layer on a composite covering layer composed of a metal matrix dispersed with particle like material on the surface of a substrate, further the thin plated layer on the surface.  
     CONSTITUTION: A composite covering layer 2 is formed by dispersing non- metallic or metallic particle in the metal matrix on the surface of a substrate 1. Then, the metal oxide layer 3 of CuO etc. providing selective absorption is  formed on the surface of the layer 2. In this case the layer 3 is formed either  by the chemical treatment after copper plating of the layer 2 or by attaching  the CuO particle by electrophoresis. Then a thin plated layer 4 which does not  cover perfectly the layer 3 is formed by electroplating. By this the aimed solar  heat absorbing object can be obtained.

Abstract: PURPOSE:To prevent a brake band from resiling upward, by securing a sun gear tight enough with a brake engagement and a one-way clutch lock in case of its one rotating direction while in case of the reverse direction, with the engagement of a band brake acting on the same direction. CONSTITUTION:In a specific change gear step, a sun gear 312 is locked and at a change gear step at the low speed side, the sun gear 312 rotates in one direction alone but at a change gear step at the high speed side, it rotates in the reverse direction. The sun gear 312 is secured tight with the engagement of a brake B2 and the lock of a one-way clutch F1 for the one rotating direction side, but for the reverse rotating direction side, with the engagement of a brake band 340 acting on the same direction as the reversed. Therefore, resiling motion in a band of the band brake can be prevented so that a torque variation in an output shaft goes smoothly.

Abstract: PURPOSE:To form a uniform gap over the entire length by applying ion beam etching to a ferrite wafer so as to form a gap slot whose bottom shape is not in parallel with a gap counter face and forming a ferromagnetic metallic film onto the gap slot only by the thin film forming process. CONSTITUTION:The gap slot 20 is formed by the ion beam etching process so that the bottom of the gap slot 20 of a couple of magnetic core halves 1a, 1b made of a ferromagnetic oxide is not in parallel with the gap counter face 14. Then the ferromagnetic metallic film 21 is formed in the gap slot 20 by the thin film processing and a couple of the magnetic core halves 1a, 1b are butte to form a magnetic gap 5. Since the ferromagnetic metallic film 21 is formed by the coating of a metal mask 18, no ferromagnetic metallic film 21 is stuck to the gap counter face 14 of a ferrite wafer 11 except the gap slot 20 thereby reducing the effect of the stress on the ferrite wafer 11.

Title: Semiconductor device
Inventor: SUMA JIROU
IPC: H01L21/66
Filed: 1982-03-17
Abstract: PURPOSE:To increase the using efficiency of measuring units and to enhance the processing capacity by a device wherein wafer checking electrodes are dispensed with along at least one side of a semiconductor chip. CONSTITUTION:Wafer checking electrodes are not arranged along one side of a semiconductor chip. Another adjacent semiconductor chip is made on a semiconductor wafer in a 180 deg. rotated relation. When both semiconductor chips are combined, their wafer checking electrodes have such a shape that they are arranged along the periphery of the combined semiconductor chips. Thus, a probe card thereof can be formed easily based on the prior art. By measuring two semiconductor chips at each time with the probe card, it becomes possible to increase the number of wafers checked by a measuring unit and also to ensure more effective use of the measuring unit. This method is also applicable to square semiconductor chips.

Title: Semiconductor laser element and manufacture thereof
Inventor: TANAKA AKIRA
IPC: H01S5/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To perform high-output oscillation at high temperatures by suppressing overflow of carriers from an active layer, to reduce the number of recombinations of carriers in an etching stop layer at the high temperatures. SOLUTION: In this semiconductor laser element, a barrier from a multi- quantum well(MQW) active layer 4 to a clad layer 62 can be made higher than those of prior art, by forming the clad layer 62 higher in impurity concentration than those in the prior art on an underside of an etching stop layer 7. This causes suppression of overflow of carriers from the MQW active layer to a clad layer 8. For this reason, at high temperatures, the number of recombinations of carriers in the etching stop layer can be reduced, the frequency of a laser threshold current becoming high is restrained, and even at high temperatures, high-output oscillating operation is carried out with a practical level of intensity.

Filed: 1984-03-05
Abstract: PURPOSE:To control a generation frequency with one control signal by adding a latch circuit to a phase comparator and connecting its output to a voltage- controlled oscillator through an analog switch. CONSTITUTION:Data inputted to the phase comparator 6 determines the frequency division ratio of a variable frequency divider 3 and also allows a low-level or high-level signal to be sent to the latch circuit 7 according to the oscillation frequency of the voltage-controlled oscillator 5. The output of this latch circuit 7 is connected to the analog switch 8, which switches voltages at the oscillation frequency band switch terminal of the oscillator 5. Thus, the generation oscillation of the frequency synthesizer device including the voltage-controlled oscillator 5 with two generation frequencies is varied with one control signal. Thus, the generation frequency is controlled with one control signal.

Abstract: PURPOSE: To perform the accurate and rapid transfer of a pinion by making the winding number of a torsion spring engaged with a shifting lever less than one winding and arranging the engaged end on the fulcrum line of the shift lever.  
     CONSTITUTION: The side surface of a torsion spring 1 is formed substantially into a U-shape, and one end 2 of the torsion spring 1 is fixed to the stationary part of a magnet switch 3, and another end 4 is engaged with a shift lever 10, both ends being formed so that they are arranged on the same line on the opposite side of the fulcrum 11 of the shift lever 10. Accordingly, the number of winding of the torsion spring 1 is less than one. Hence, since there is no adjacent spring wire, when the spring is deflected or restored, there is no frictional loss, and the small load of the magnetic switch may be enough. Further, the return of the pinion 8 becomes excellent. Therefore, the transfer of the pinion 8 can be performed more accurately and rapidly, and the manufacture of the device becomes easy and the reduction of the cost becomes possible.

A voltage is applied to single coils A and B, via a communication selection means 14 from a power supply 12 at a first energization time. At the same time, a differential amplifier 16 detects a back electromotive force that is generated between the center tap T and the closed circuit edge part of the coil C and judges whether or not a rotating speed has reached a specific value according to the level. When the speed has not reached a specific value, a second set of coils consisting of at least one coil out of two set of coils are energized, thus improving the matching accuracy and speed of the rotor 10.
