Title: Photoelectric converter and converting method
Inventor: MACHIDA SATOSHI
IPC: H01L31/108
Filed: 1995-03-22
Abstract: PURPOSE: To enhance the residual image characteristics significantly, in the storing operation or reading operation, by providing means tor directing the electromagnetic wave, other than that generated from an object, to a transistor. CONSTITUTION: First main electrode region, i.e., the emitter region 2, of an NPN bipolar transistor 1 is connected with the drain of an N-channel MOS transistor 5 which is controlled to be turned ON/OFF by means of a signal ϕR. Second main electrode region, i.e., the collector region 4, is held at positive potential and the control electrode region, i.e., the base region 3, is normally floating. Electromagnetic wave, other than that generated from an object, is directed to the NPN bipolar transistor 1. Since carriers are generated in the control electrode region or injected thereto, in addition to the carriers generated by the electromagnetic wave generated from the object, the quantity of excessive majority carriers can be kept at a constant level in the control electrode region after reducing operation.

Title: Production of liquid crystal display device
Inventor: ONO YOICHI
IPC: G02F1/1337
Filed: 1986-03-20
Abstract: PURPOSE:To obtain the titled device having an uniform orientation and a large tilt angle of the liquid crystal in a low cost by a method of a mass production by forming an orientation layer which orientates the liquid crystal molecule to one direction, with a specific silane coupling agent.

Title: Soundproofing material
Inventor: KASAHARA SHIGEYUKI
IPC: G10K11/16
Filed: 1990-03-14
Abstract: PURPOSE:To increase the soundproof effect to facilitate execution of works and carrying by evacuating the internal space of a plate-shaped structure formed into a closed box shape and interposing spacers between wall plates facing each other. CONSTITUTION:The internal space of a plate-shaped structure/formed into a closed box shape is evacuated, and spacers 4 are interposed between wall plates 2a and 2b facing each other and are brought into contact with wall plates at points. Consequently, the acoustic wave which collides against the wall plate 2a is reflected as the reflected sound by the wall plate 2a, and the acoustic wave which penetrates the internal space is not transmitted to the other wall plate 2b because of the evacuated space. The acoustic wave is difficult to be transmitted to spacers 4 and is minimized though penetrating the space because the apex 4a of each spacer 4 is brought into contact with a point of one wall plate 2a, and the acoustic wave is radially diffused and attenuated because the spacer 4 is conical. Thus, the soundproof effect is improved, and the weight is reduced, and execution of works and carrying are facilitated.
