Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To obtain a bidirectional shift register whose constitution is simpler and to obtain a bidirectional shift register which can be changed into an LSI with a small area. SOLUTION: In a forward transfer operation, data which is held by the parasitic capacitor C0 of an inverter I01 is driven by an inverter I02 , and it is transferred to an inverter I11 through a switch T0 and a switch S21 so as to be held by its parasitic capacitance C1 . In a reverse transfer operation, data which is held by the parasitic capacitance C3 of an inverter I31 is transferred to an inverter I21 via an inverter I32 , a switch T3 and a switch S22 so as to be held by its parasitic capacitor C0 . An odd-numbered switch S11 and an add- numbered switch S12 are switching-controlled by one of two-phase clocks, and the switch S21 and the switch S22 are switching-controlled by the other clock. When a switch T1 and a switch T3 are turned on or off according to a transfer direction, the switch T0 and a switch T2 are controlled so as to be turned off or on by the other clock.

IPC: C03C3/06
Filed: 1987-05-07
Abstract: PURPOSE:To contrive prevention of occurrence of bubbles in glass, by impregnating the surface of a wet gel obtained from an alkoxide with an aqueous solution of an Al or Ti salt or hydrolyzate solution thereof, drying and sintering the impregnated surface. CONSTITUTION:A solution consisting essentially of an alkoxide is hydrolyzed to form a sol, which is subsequently gelatinized to afford a wet gel. The surface of the resultant wet gel is then sufficiently impregnated with an aqueous solution of an Al or Ti salt or hydrolyzate solution of an alkoxide thereof, dried and then sintered. Since the Al or Ti in the form the aqueous solution of the salt or alkoxide is added to the surface and impregnated thereinto, filling of pores on the gel surface can be delayed. Thereby bubbles in the glass are pushed to the outside and the filling of pores is completed to prevent the occurrence of bubbles in the glass.

Filed: 1986-05-15
Abstract: PURPOSE:To obtain an output signal without beat disturbance by deciding the width of a switching frequency to be a width being 1/2 or over of a tuning frequency band width, selecting only a side band of an AM signal without being mixed with harmonics and demodulating it. CONSTITUTION:The n-th order of the switching pulse generated from a pulse switching device is mixed to only either an upper side band or a lower side band of an AM signal. To which of the upper or lower side band the harmonic is mixed is discriminated by a discriminating means 4 based on the carrier frequency detected by a tuning frequency detecting means 3. If the harmonic is mixed to the upper side band as the result of discrimination, a demodulation signal from a lower side band separating means 2 by a changeover means 5 and if the harmonic is mixed to the lower side band, a demodulation signal from the upper side band separating means 1 is extracted. The extracted demodulation signal is a signal obtained by demodulating an AM signal without being mixed with harmonics and a beat sound generated from an on-vehicle radio receiver is eliminated.

Filed: 1986-05-17
Abstract: PURPOSE:To prevent the radiating and electrical characteristics from deteriorating by a method wherein a semiconductor chip is pressurized to adjust the thickness of solder layer to specified value and the solder layer, after expelling bubbles therefrom, is cooled down. CONSTITUTION:When a pressurizing block 3 is lowered to make a press down block 3a pressurize a semiconductor chip C, a solder layer L below the semiconductor chip C is pressed down to extrude the solder layer L from the position below the semiconductor chip C so that the thickness of solder layer L may be reduced while expelling the bubbles contained in the solder layer L. When the thickness of solder layer L below the semiconductor chip reaches the specified value, the press down force upon the pressurizing block 3 is released to lower the second holding and heating block 2 so that the heating of leadframe F by the block 2 may be stopped to cool down and solidify the solder layer L. Through these procedures, the electric characteristics of semiconductor device can be prevented from deteriorating.

Title: Manufacture of integrated circuit
Inventor: HATSUYA AKIRA
IPC: H01L29/732
Filed: 1990-04-26
Abstract: PURPOSE:To provide a semiconductor device having a laminated intermediate layer composed of a silicon nitride layer and a insulating polyimide layer with very fine through holes by forming the polyimide layer after removing a first resist pattern, and removing the polyimide layer with a second resist pattern used as a mask. CONSTITUTION:A hole is first opened only in a silicon nitride film 39 to prepare a connecting part of a thin through hole 41 before an insulating polyimide 40 is formed. A larger hole, extending to the connecting part, is opened in the insulating polyimide 40 by photoetching. The through hole 41, as a whole, is very thin because its portion in the substrate nitride film 39 is made very finely by the first photoetching process. Therefore, the packing density of an integrated circuit is little affected even if the hole in the silicon nitride 40 is large.
