Abstract: PURPOSE:To prevent the mutual diffusion of p-type impurity and n-type impurity in a semiconductor device, in which n+ regions and p+ regions are mixed in the polysilicon of a multilayer film of polysilicon and silicide. CONSTITUTION:In a semiconductor device having a multilayer film of polysilicon films 9a, 9b and high-melting point silicide film 12 and equipped with both p+ regions and n+ regions in the polysilicon films 9a, 9b, boron in the silicide film 12 has no concentration gradient. Even if heat treatment is conducted, consequently, neither baron in p+ polysilicon decreases nor phosphorus or arsenic in n+ polysilicon film diffuses into p+ polysilicon film. Therefore, a threshold voltage(Vt) shows no change when a policide film is used in the gate electrode of MOSFET, and a contact resistance does not become higher when the film is used in a wiring for connecting n+ diffused layer and p+ diffused layer.

Title: Light temperature detection system
Inventor: SASAKI NOBUO
IPC: G01J5/28
Filed: 1978-12-21
Abstract: PURPOSE:To make it possible to detect light and heat with the same unit and take out large signals from the small-size unit by utilizing that the current flowed to a semiconductor device is changed according to light or temperature and reading the current change. CONSTITUTION:By applying sharp-break pulse PG to gate electrode 6 of a MISFET repeatedly, charge is stored in semiconductor layer 2 floated electrically to change the threshold voltage of the transistor. When light or heat is applied to the semiconductor device of this state, the opposite-direction leak current in pn junction is increased, and charge stored in floating substrate 2 disappears. Consequently, the threshold voltage is returned to the initial value, and the drain current is increased. Then, light or heat can be detected by measuring change of the drain current by output terminal Ot. Signals obtained at output terminal Ot can be made large by raising the applied voltage even in case of a small-size unit.

Title: Refrigerating cycle
Inventor: MATSUDA NORIMOTO
IPC: F04B39/06
Filed: 1981-10-09
Abstract: PURPOSE:To make it possible to always maintain stable intake gas, by arranging a throttle mechanism just before the intake port of a chamber in a compressor so that refrigerating cycle lowers the temperature of coolant flowing into the chamber, directly before the latter upon high load operation, but evaporates the coolant upon low load operation. CONSTITUTION:A throttle mechanism 10 having an orifice-like small cross-section part 16 is arranged just before an intake port attached to a chamber 13 in a closed-type compressor. Therefore, if coolant flowing into the throttle mechanism is completely in a gas state just before the throttle mechanism, the temperature of gas is subjected to a temperature drop equal to that obtained through adiabatic expansion which is carried out corresponding to the pressure drop of gas. Further, if the coolant just before the throttle mechanism 10 contains liquid coolant in part, the coolant is subjected to vaporization due to the pressure drop through the throttle mechanism 10, so that the coolant becomes complete gas coolant upon the entrance of the coolant into the chamber 13. Thus, intake gas is stably maintained irrespective of load fluctuation, thereby the compressor may be stably operated.

Title: Numerical controller
Inventor: OTSUKI TOSHIAKI
IPC: G05D3/12
Filed: 1995-06-27
Abstract: PURPOSE: To perform operation for positioning efficiently by using a manual pulse generator by converting a fast-forward pulse speed into an integral multiple of set magnification. CONSTITUTION: The manual pulse generator 11 generates a pulse speed by the rotation of a handle. With a manual handle feed quantity setting switch 12, magnification is set. A movement quantity calculating means 21 doubles the pulse speed from the manual pulse generator 1 to find a double pulse speed. The fast-forward pulse speed is converted into an integral multiple of the set magnification and the double pulse speed is compared with the fast-forward pulse speed converted into the integral multiple. When the double pulse speed is larger in this case, the fast-forward pulse speed which is converted into the integral multiple is outputted as a clamp pulse speed to an axis control circuit 26. Consequently, the movement quantity of a cutting tool is easily grasped and the positioning operation, etc., can be done efficiently by using the manual pulse generator 11.
