Title: Light emitting diode array chip and manufacture thereof
Inventor: OKI KAZUHIRO
IPC: H01L21/205
Filed: 1993-03-25
Abstract: PURPOSE:To manufacture a light emitting diode array, in which individual light emitters are separated surely and the chip has flat surface. CONSTITUTION:A recess 32 to serve as a light emitter 35 is made on the first layer 31 being epitaxially grown on the surface of a crystal substrate 30. The second layer 33 to show the opposite conductivity type to the first layer 31 is epitaxially grown on the surface of the first layer 31 including the recess 32. The plane 34 of the second layer 33 are removed by etching so as to put the second layer 33 on a level with the first layer 31. Hereby, the second layers 33 in the recesses 32 are separated from each other, and become individual light emitters 35. Accordingly, the surface of the chip become flat, so there is no trouble such as wire breaking, short circuit, etc., when forming an ohmic electrode 38. Moreover, there is no light leaking from the side of the light emitter 35 unlike a mesa type, and a high-quality print can be gotten.

Title: Integrated circuit
Inventor: MONMA HIDEO
IPC: H01L21/822
Filed: 1980-05-20
Abstract: PURPOSE:To reduce the power consumption of an integrated circuit which tests the internal circuit at the output terminal used for other utility commonly used for this test at its operating time by forming a test signal pull-down or pull-up resistor of a transistor. CONSTITUTION:T2 is a reset terminal and T0 is an alarm terminal in case, for example, that they are applied for an LSI for an electronic watch. QP5 and QN5 are transistors forming a pull-down resistor R1, which are so controlled as to become a high resistance value when the input of the set terminal TR is H and an optimum low resistance value as a pull-down resistor when the input is L. QP6 and QN6 are transistors forming a pull-down resistor R2, which operate in reverse manner to the QP5 and QN5. The circuit is tested by applying the L to the input of the terminal TR and a test signal ST to the terminal T0. Since the input of the terminal TR is H at the ordinarily operating time, the transistors QP5, QN5 are together shut OFF, resulting in no flow of wasteful charge.

Title: Solenoid valve of proportional type for very small flow
Inventor: WACHI AKIRA
IPC: F16K31/06
Filed: 1983-04-14
Abstract: PURPOSE:To achieve a stable control of very small flow, by making the contact surface between the nozzle and the flapper adapted so that the flow characteristic in the produced passage of the fluid is gradually varied as the contact is gradually released. CONSTITUTION:The top surface 20 of the nozzle 19 is made into a conical shape. In this surface is provided a groove 21 so that its end is within the external diameter D of the nozzle, whereby an ungrooved surface 22 is left there. When the starting current of the valve is exceeded by the driving current, the flow comes to be controlled by the very small gap left between the groove 21 and the elastic member of the flapper filling the groove. If the driving current is further increased, the pressure of the flapper acting on the groove is further decreased, whereby the sectional area of the passage of the fluid in the groove 21 is gradually increased to further increase the flow of the fluid.

Title: Conveying device for sheet material
Inventor: CHOKAI MOTOTADA
IPC: B65H20/02
Filed: 1985-04-03
Abstract: PURPOSE:To enable a sheet material to be stably conveyed by configurating a device in such a way that friction coefficient of the outer surface of a conveyor roller at that section opposite to a conveying reference which corresponds to the edge of the sheet material of small size, is made smaller than that of the other portion in a copying machine and the like. CONSTITUTION:A conveyor roller 23 which is in touch with a conveyor roller 5, is composed of a roller portion 25 which is made of rubber and the like of high surface friction coefficient mu, and of a roller portion 26 which is made of a material of surface friction coefficient mu' lower than that of the roller 25, for example, a nickel plated surface. And the roller portion 26 is designed to cover the area which includes the edge of a small size but thick fixed form P' that is assumed to be practically used, where the edge is in the opposite side of a conveying reference. Accordingly, conveying force by the conveyor roller 23 will be muW for the roller portion 25, and will be mu'W for the roller portion 26 where W represents distributed pressure. In this case, as mu>mu', conveying force is well balanced allowing no oblique motion to occur. On the other hand, when the sheet material of large size is conveyed, as conveying force of the roller portion 26 is weak, conveying force itself is out of balance at the right and left sides. However, no oblique motion occurs because the form is extensively in touch with the roller.

IPC: H01L21/205
Filed: 1989-03-20
Abstract: PURPOSE:To effectively prevent the deformation and modification of a substrate generating while the temperature rises up to the vapor growth temperature, by using a preliminary heating susceptor which does not support the substrate, and a susceptor which supports the substrate and is not subjected to preliminary heating (heated instantaneously up to the growth temperature by thermal conduction).

The preliminary heating susceptor 7 heated previously and the susceptor 8 come closely into contact with each other on the facing surfaces, and constitute a unified susceptor. When the preliminary heating susceptor 7 comes closely into contact with the substrate retaining susceptor 8, the heat travels rapidly from the former to the latter, and consequently the substrate 4 is heated at once up to the growth temperature. Thereby an excellent epitaxial growth layer can be grown on the substrate.
