Title: Semiconductor integrated circuit provided with mis transistor
Inventor: SASAKI MINORU
IPC: H01L27/02
Filed: 1990-10-08
Abstract: PURPOSE:To effectively provide a protective resistance area using small empty space by allowing the protective resistance area to have high resistance value as a low-concentration Si substrate or a well in the substrate. CONSTITUTION:The protective resistance R1 of a pchMOSFETTp is brought into contact with a channel stopper 4n through a connecting hole 24a and possesses an Al wiring 26 which connects to a gate electrode Gp through an Al wiring 24 connected to a VDD, the N<+> layer 25 and the hole 26a of an n-type Si substrate. The area of the protective resistance R1 is actually an unbounded local area between the channel stopper 4n and a connecting area 52 in the Si substrate 1. The protective resistance R2 of an nchMOSTn is an unbounded local area between a channel stopper 4p and a connecting area 28 in a (p) well in the same manner and since the substrate 1 and the well have both low impurity concentration, the R1 and R2 become large enough value and a gate insulating film is well protected from noise and surge when turning on power source. Such constitution permits to provide the high protective resistance even with a low resistance channel stopper, etc.

Title: Laser module temperature control circuit
Inventor: SAKAMOTO HIROTOKU
IPC: H01S5/06
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To obtain a laser module temperature control circuit of a simple constitution based on voltage control wherein the overheating of a Peltier element caused by an excess current at the starting of power supply, and the breakdown caused by low temperature solder fusing are excluded, by controlling the Peltier element when a unipolar power supply and a low voltage. SOLUTION: When the internal temperature of a laser module 2 rises, the resistance value of a thermistor 22 decreases, because the thermistor 22 has a negative temperature coefficient, so that the + input terminal voltage of an operational amplifier (2) 12 decreases. The output voltage of the operational amplifier (2) 12 decreases, and the + terminal voltage of a Peltier element 21 decreases, and the temperature of the Peltier element 21 decreases. As the result of cooling operation, the temperature decreases, the thermistor resistance value increases, and the + input terminal voltage of the operational amplifier (2) 12 increases. Thereby the + terminal voltage of the Peltier element 21 is increased, and the temperature of a laser module 2 is kept constant, so that the Pelitier element breakdown caused by an excess current can be prevented and a circuit can be simplified.

Title: Very low temperature insulating container
Inventor: AMANO TOSHIYUKI
IPC: F25D3/10
Filed: 1992-09-16
Abstract: PURPOSE:To keep small an eddy current loss even under a fluctuating magnetic field to acquire excellent heat insulating performance by providing a composite structure consisting of a high resistance non-metal material layer and a metal structure material layer for a thermal shielding plate. CONSTITUTION:The basic operations of an ultra-low temperature insulating container are same as that of the prior art, that is, it can avoid thermal convection with installation of vacuum spaces 6a, 6b and also can reduce the amount of radiation of heat to an inner vessel 2 by providing a heat shielding plate 4. But, generation of only small eddy current is permitted for operations by AC or pulse signal which brings about a large variation of magnetic field with time by using a ceramic layer 4a of a silicon carbide group having high resistance and high conductivity as the heat shielding plate 4. However, since use of only ceramic layer 4a of the silicon carbide group makes difficult application into the heat shielding plate 4 in various shapes, such ceramic layer 4a of the silicon carbide group is bonded to a metal structure material layer 4b with a bonding agent layer 4c.
