Title: Liquid crystal display device
Inventor: YOSHIMOTO HATAAKI
IPC: G02F1/1365
Filed: 1988-04-13
Abstract: PURPOSE:To correct the difference in the optical characteristics of the title device against each light of red, green, and blue by using a varister as a nonlinear element and controlling the threshold voltage of the varister. CONSTITUTION:A varister is usually used as a surge absorbing element. The varister has such characteristics against an electric current that the current does not flow practically through the varister when the voltage applied across the varister is lower than a fixed level (varister threshold voltage Vth) since its resistance is high, but the current is made flow when the voltage exceeds the threshold voltage Vth since the resistance abruptly drops. Therefore, by utilizing such characteristics of the varister, the voltage applied across a picture element electrode and an electrode is controlled by adjusting the distance between the electrodes, particle size, and quality of the material. Accordingly, the voltage-contrast characteristics against each light of red, green, and blue can be improved and a liquid crystal display device improved in visibility can be obtained.

Title: Flat type semiconductor device
Inventor: SAOTOME MASANORI
IPC: H01L21/52
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To make offset of a spring hard to occur during transportation of an element by constituting an integral spring by mutually connecting unit springs which press each contact terminal to each semiconductor chip without pressurizing an upper board and a lower board which hold a semiconductor chip and a contact terminal body from top and bottom. SOLUTION: A unit spring 31 is formed by bending an annular spring material whose outer shape is almost square, and an integral spring 30 is constituted by connecting the unit springs 31 mutually by an outer frame 32. The integral spring 30 is used so that the outer frame 32 and a leg part 35 of the unit spring 31 come into contact with an upper board and a top 33 of the unit spring 31 comes into contact with a contact terminal. The unit spring 31 is a plate spring. According to this constitution, it is possible to reduce the number of parts when compared to a flat type semiconductor device wherein a separate spring is used for each semiconductor chip, thus greatly reducing the number of processes during assembly. Furthermore, offset of spring caused by transportation, etc., can be prevented since the spring is formed to an integral spring.
