Title: Planar type semiconductor device
Inventor: KAI SHIYUNICHI
IPC: H01L21/314
Filed: 1983-04-20
Abstract: PURPOSE:To enhance the withstand voltage of a semiconductor device without losing characteristics such as a switching velocity, a saturable characteristic and reverse withstand voltage by increasing the controlling margin of a boundary charge density of a semiconductor substrate. CONSTITUTION:The entire surface of a semiconductor substrate is covered with the first film 16 and the second film 17. The film 16 is formed of a semi-insulating film having 7 or more of dielectric constant such as a polysilicon carbide. The film 17 is formed of an insulating film having large diffusion blocking ability of contaminating ion nuclide having 7 or more of dielectric constant such as Al2O3. Since a leakage electric field can be effectively shielded by providing the above first and second films and an electric field produced in a semiconductor substrate 1 can be shared in the first and second films, the concentration of the electric field on the surface of the junction can be effectively alleviated.

Abstract: PURPOSE:To eliminate a force cooling and to provide a rapid, positive and accurate response in a liquid pressure control recording method by the heating of a recording liquid in which a thermal acting surface contacting with the liquid to be heated is changed to a specified temperature to cause the time to be a specified value. CONSTITUTION:When the pulse signal which is turned ON or OFF at the times tO and tP is applied to the heater means 2, a surface temperature at the thermal acting surface 9 contacting with the thermal acting part 7 of orifice 5 being heated is changed from a starting temperature Ti to the maximum temperature Tp as the  time is passed and shows a variation illustrated in a curve. When the value is 0< tau0<= 10mus, the relation of tau0<=tau1/2<=4tau0 is defined and when the value is 10mus<tau0, the relation 10mus<=tau1/2<=4tau0 is defined, then it is technically possible to have a rapid rise-up curve. In turn, when the energization to the thermal resistance layer 11 is turned off, the heat found at the thermal acting part 7 and the heat generating part 8 is discharged rapidly to the base plate 3 side.

Filed: 1987-03-26
Abstract: PURPOSE:To prevent supercooling of a form bet, by a method wherein a humidity sensor and a temperature sensor are disposed in place in a room separately from the form bed, and according to a theoretical calculation based on the values measured by the sensors, the temperature of a coolant is adjusted to be relatively high around a dew point at the measurement time. CONSTITUTION:According to the data of humidity and temperature of a room air detected by a humidity sensor 14 and a temperature sensor 15, a CPU 24 computes a dew point at the detection time, furthermore calculating a required set temperature. The obtained set temperature is compared with a coolant temperature detected by a coolant temperature sensor 16. The operation of a coolant circulator 11 is so controlled through an interface 25 that: if the coolant temperature is higher than the set temperature resulting from the calculation a circulating pump is started, and contrary, if the coolant temperature is lower than the set temperature the circulating pump is stopped. In this manner, the temperatures of a form bet of a lithographic proof press and a pressplate which is loaded thereon can be kept around the dew point corresponding to the humidity and temperature in the operation room.

Abstract: PURPOSE:To reduce the diameter of an anode frame body while induced reactance is being kept in a preset value by providing recesses and protrusions that are long in the axial direction and are wave-formed in the circumferential direction on the inner surface of an anode cylinder and additionally providing anode veins protruding toward cathodes at the protrusions of these recesses and protrusions. CONSTITUTION:An anode cylinder 5 made of pure copper has recesses and protrusions 6a, 6b, 6c, 6d, ... that are long in the axial direction and are wave- formed in the circumferential direction on the inner surface and anode veins 3a, 3b, ... are additionally provided at the protrusions 6b, 6d, ... of these recesses and protrusions. Since the recesses 6a, 6c, ... are made circular and their radius is considerably smaller than the inner surface radius of the anode cylinder 5, the substantial inner surface radius r2 of the anode cylinder 5 becomes larger than the inner surface radius of the conventional anode cylinder and the substantial protruded length l3 of the anode veins 3a, 3b, ... becomes larger than the mechanical length. As a result, while induced reactance is being kept in a present value, the inner and outer surface radiuses r and R of the anode cylinder 5 and the mechanical length of the anode veins 3a, 3b, ... can be reduced.
