Title: Package for accommodating semiconductor element and manufacture thereof
Inventor: NOMOTO OSAMU
IPC: H01L21/50
Filed: 1984-09-18
Abstract: PURPOSE:To enable a metal plate to be brazed to an insulative frame body in a horizontal state without warpage, by utilizing brazing materials having different melting points for brazing the insulative frame body and the metal plate and for brazing the metal plate and a heat conductive plate. CONSTITUTION:A first brazing material 8 interposed between an insulative frame body 1 and a metal plate 3 is heated to braze the metal plate 3 to the frame body 1. A heat conductive base body 4 is put on the metal plate 3 with a brazing material 9 interposed therebetween and heated under this condition such that only the brazing material 9 is melt, whereby the base body 4 is brazed to the metal plate 3. The brazing material 9 having a lower melting point than that of the material 8 is selected. If a package is produced in this manner, the metal plate 3 can be brazed to the frame body 1 in horizontal state without any warpage and therefore the substrate 4 also can be brazed thereon in horizontal state. Accordingly, a semiconductor element 5 can be attached to the base body 1 with an extremely high bonding strength.

Inventor: RAJIVAN SATHYANANDAN
IPC: H03K19/0948
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To make an object circuit capable of variably tuning an object parameter by generating corresponding tuning pattern signals and selectively using the different tunable parts of the object circuit. SOLUTION: A tuning state corresponding to a desired circuit parameter for the object circuit 101 is loaded through input nodes 112a and 113a to latches 332 and 113. The input nodes 112a and 113a receive serial input data streams (A and B) for indicating the desired tuning state so as to reduce the number of input/output pins required for the tunable circuit 100. The tuning states are obtained in the output nodes 112C and 113c of the latches 112 and 113 and respectively sent to the input nodes 1148 and 114b of a decoder 114. Then, the decoder 114 converts the tuning state to a selected tuning pattern at the output node 114c and it is sent to the input node 101a of the object circuit 101.

Title: Supercharger of internal-combustion engine
Inventor: TAKAMATSU KAN
IPC: F02B27/02
Filed: 1981-12-03
Abstract: PURPOSE:To prevent a reduction of charging efficiency by reliably preventing the temperature of the intake air into an engine from rising by the excessive supercharged air  sucked again into the supercharger when the excessive air is released to control the supercharge pressure during a mechanical supercharge in the supercharger using the  mechanical supercharge and inertia supercharge in combination. CONSTITUTION:Until the engine speed reaches a medium speed, the pressurized air is  fed into an intake air passage 12 by driving a supercharger 2. At this time, a check  valve 13 is closed and the reverse air flow into an air cleaner 11 is blocked. All the pressurized air from the supercharger 2 is fed into the engine, which is then driven by  a mechanical supercharge. At a medium engine speed or higher, the air quantity from  the supercharger 2 tends to be deficient for the intake air quantity into the engine.  When the pressure in the intake air passage 12 becomes equal to or lower than the  atmospheric pressure, the check valve 13 is opened and the atmospheric air is directly  introduced through the air cleaner 11. The length (l) of the intake air passage from a  surge tank 8 to combustion chambers of individual cylinders is set so that the intake air quantity becomes maximum at the medium or higher engine speed range, in which  an inertia supercharge is performed.

Abstract: PURPOSE:To eliminate uneven colors in a very small part and uneven orientation of a liquid crystal by ruggedness and to improve line drawing accuracy of respective colors by forming a pattern on a transparent substrate by a printing method using a dyeable resin and dyeing the pattern. CONSTITUTION:The gelatin resin is printed in the striped pattern of 150mum width by gravure offset printing of the glass substrate 41 to form the pattern layer thereon. The substrate is immersed for 60sec into Congo Red after printing by which the pattern is dyed red. The pattern is thereafter treated with tannic acid and tartar emetic to fix the dye to obtain an R filter. The gelatin resin is then printed adjacently to the R filter to form another pattern layer which is dyed green by Acid Milling Green to form a G filter. A B filter is printed in the same manner as for the R and G filters after the fixing treatment and is dyed by Dia Cotton Blue, then the filter is subjected to the fixing treatment. The CF of three colors of R, G and B is Thus formed by 3 times of printing and dyeing.
