Title: Semiconductor device and manufacture thereof
Inventor: KIN SAIKO
IPC: H01L21/8238
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To minimize the threshold voltage difference between a first and second p-wells by placing first and second p-type doping regions near the surface of the second and first wells, the concn. of the first region being lower than that of the second. SOLUTION: N-type impurity ions are implanted to form a first threshold voltage adjusting layer 12A (first doping region) on the surface of a semiconductor substrate 1, and p-type impurity ions are implanted to form a second threshold voltage adjusting layer 13A (second doping region) on the surface of first and second p-wells 13 and 113, such that both adjusting layers 12A, 13A are formed on the second p-wells 113 to mutually counter-dope them, thereby forming the adjusting layers 12A, 13A having a concn. in the second p-wells lower than that of the adjusting layer 13A in the first p-wells 13. Hence the threshold voltage of the second well 113 becomes lower than that of the first well 13.

Title: Transmitter and receiver
Inventor: TSUTSUI TORU
IPC: H04B10/00
Filed: 1984-09-07
Abstract: PURPOSE:To switch an electric signal line simply with an optical signal independently of noise by means of an optical connector on market when an electric noise is generated or it is possible that a noise is generated by detecting a specific signal included in an optical signal or the optical signal itself at the reception side to switch the input to a receiver from the electric signal position to the optical signal position. CONSTITUTION:A specific signal such as a prescribed period of synchronizing signal or a clock signal included in an optical signal transmitted from an optical cable 1 is extracted by a filter 8. A level detector 9 is provided to prevent malfunction due to noise, and when an output of the filter 8 reaches a prescribed level or over, the level detector 9 generates an output to excite a relay to switch a moving contact 5 to a fixed contact 7 at the optical signal side. When a specific frequency signal is not included in the optical signal, the specific signal has only to be superimposed on the optical signal at the transmission side. Further, the transmission of the optical signal is started from the transmission side at switching to detect the optical signal itself thereby operating the switch. In this case, no filter 8 is required.

IPC: H05K3/02
Filed: 1988-07-26
Abstract: PURPOSE:To enable the manufacture of a wiring circuit board provided with a wiring circuit high in density and accuracy and excellent in adhesion by a method wherein a board of SiO2-Al2O3-MgO glass ceramic, whose compositional ratio is specified, is employed and its surface is chemically roughened before a conductor metal layer is formed on it.

If the compositional ratio of SiO2 exceeds 63wt.%, a sintered body of high denseness can not be obtained, and if the ratio is less than 48wt.%, a crystallizing rate rises, and when the compositional ratio of Al2O3 exceeds 25wt.%, the board can not be sintered enough at a temperature lower than 950 deg.C, because a sintering temperature rises, and when the ratio is less than 10wt.%, a cordierite crystal becomes less and a crystal of SiO2-MgO is much separated, therefore a relative dielectric constant increases.

Abstract: PURPOSE:To obtain an engine heat pump device which can prevent the engine from being overloaded even when the temperature of air sucked into the evaporator is high, which can improve the hot water supply capacity and which can be operated at high efficiency, by a method wherein a part or the whole of the air passed through the evaporator is circulated toward the upstream side of the evaporator. CONSTITUTION:In summer in which the temperature of the intake air is high, the pressure of the coolant on the outlet side of the evaporator 15 becomes high and the diaphragm 36 of the drive device 35 moves toward the driven chamber 38. Further, the damper 32 closes the exhaust port 29 by the rack 34 and the pinion 33 and is driven to open the circulating passage 31. Accordingly, air passed through the evaporator 15 and cooled by the fan 30 circulates toward the upstream side of the evaporator 15 through the circulation passage 31. As a result, the temperature of the air sucked into the evaporator and the pressure of the coolant becomes low so that the damper 32 is driven to open the exhaust port 29. The opening and closing operation of the damper 32 is performed continuously in proportion to the pressure of the coolant and it is possible to continuously operate the heat pump by preventing the engine from being overloaded without reducing its efficiency.

To tune an offset signal, the signal is tuned on the basis of an optionally set frequency f1ST, the difference from the prescribed frequency fP2 is further detected, and frequency correction is performed on the basis of the detection result. The channel selecting device is therefore surely tuned to the offset signal.
