Patent JP-S61256662-A (JP)
Title: Manufacture of resin-sealed semiconductor device
Inventor: KUJIRAI MASAYOSHI
IPC: H01L21/306
Filed: 1985-05-08
Abstract: PURPOSE:To reduce the cost of a lead member by etching for removing a machining strain in some degree in the state of a sole laminated chip, thereby decreasing the etching resistance requested for the lead member. CONSTITUTION:A laminated chip 6 is dipped in a known silicon etching mixed acid solution of fluoric acid-nitric acid series to etch away the side of the semiconductor part 1a of the chip 6 to the depth of approx. 30mum. Since a brazing material layer 2 is hardly etched as the result of adding Ag, the projection 2b of the layer 2 is formed. Since a solder layer 4 is hardly etched, the chip 6 does not continue to be etched from both end sides thereof. Then, the chip 6 is dipped in a solution of sodium hydroxide or hydrochloric acid to etch away the projection 2b of the brazing layer. Thus, bent or collape of the projection 2b in the state of the layer 6 can be eliminated. Subsequently, leads 7a made of Ag-coated Cu wirings are connected by the layer 4 with both ends of the chip 6. Thereafter, the chip 6 is dipped to remove by etching the side of the semiconductor part 1a of the chip 6 in the depth of approx. 30mum. As a result, the machining strain layer of the part 1a can be completely removed, and the projection 2c of the brazing layer can be newly formed.

Title: Optical switch and deflecting method for monochromatic luminous flux using the same
Inventor: MIYAGI KOICHIRO
IPC: G02F1/31
Filed: 1990-04-12
Abstract: PURPOSE:To enable high-speed switching by deflecting monochromatic luminous flux which is made incident from outside an optical piezoelectric crystal body by lattice-shaped strain caused in an area by an inter-digital type transducer and projecting the luminous flux when a voltage is applied. CONSTITUTION:Electrooptic effect is generated with the voltage which is applied to the interdigital type transducer 2 to cause periodic variation in refractive index on the surface of a lithium niobate crystal substrate 1. The incident luminous flux 6 is Bragg-diffracted by he periodic and partial variation in the refractive index caused when the voltage is applied to the interdigital type transducer 2, and then diffracted light 7 which is reflected internally by the crystal surface and projection light 8 of 0-order which is merely reflected in the crystal when no voltage is applied are projected. Consequently, the luminous flux which has a hundreds of mum - several mm diameter can be switched in a short time of shorter than hundreds of ns.

IPC: H03K23/50
Filed: 1985-05-08
Abstract: PURPOSE:To obtain a frequency division circuit hardly malfunctioning due to a radiant ray by processing majority decision to signals outputted from flip-flop inverting output terminals and leading a majority decision signal to a frequency output terminal and a data terminal. CONSTITUTION:When a clock signal 100 changes from '0' to '1', D flip-flops 1-3 read an output signal 107 of an OR circuit 7 inputted to the respective data terminal, hold it and output its inverting logic signal to an inverting output terminal (Q'). The output 107 of the OR circuit 7 is constituted that it is '1' when >=2 of outputs 101-103 of the D flip-flop 1-3 are '1' and '0' is outputted when >=2 are '0'. Thus, even when one D flip-flop 1-3 are '1' and '0' is outputted when >=2 are '0'. Thus, even when one D flip-flop is malfunctioned due to a radiant ray and the state inversion takes place, a correct signal is applied to the data terminals of all the flip-flops.

Title: Control device of idle speed in engine
Inventor: MATSUURA MASAHIKO
IPC: F02D35/00
Filed: 1983-06-03
Abstract: PURPOSE:To finely control an idle speed, by providing a feedback control means, which outputs a control signal to a control valve controlling an intake air amount, and an open control means which outputs a control signal to the control valve within a prescribed range. CONSTITUTION:A feedback control means outputs a control signal by a signal from a speed detecting means for a control valve which controls an intake air amount. If a speed focusses in a speed variation width within a blind area, the signal from the feedback control means to the control valve is stopped and switched to a signal from an open control means. A setting means detects the speed variation width for every load condition each time, determining the blind area for switching from the feedback control to the open control on the basis of said speed variation width. In such a way, idle speed can be controlled in fine reliability.
