Title: Method and device for preionied laterally excited laser
Inventor: PIITAA PII CHIENOOSUKII
IPC: H01S3/0971
Filed: 1991-02-22
Abstract: PURPOSE: To increase laser output by performing the circulating operation of a high energy circuit having no switching operation through a low-energy circuit, namely, a circuit for applying comparatively little energy to gas discharge. CONSTITUTION: Pulse DC energy is supplied to a laser, by discharging a capacitor C6 charged from a DC source 26. DC or low-frequency AC power is applied from an energy source, installed as the DC source 26 and the capacitor C6 to the laser. A filler to be resonated in parallel to the frequency of an RF source 24 blocks the transmission of RF energy to AC and DC sources. Namely, for the filter to function as an RF trap, the RF cuts off AC or DC energy or a power source. A variable inductor for delaying the rise time of a current from the energy source 26 to laser discharge first sends a DC current from the capacitor C6 to a gas discharge and is ionized, before supplying gas in a laser cavity from a high-energy source for discharging.

Title: Phase detector
Inventor: MAENO TAKAYOSHI
IPC: G01R15/06
Filed: 1995-02-17
Abstract: PURPOSE: To facilitate countermeasure against corona while reducing the size by providing an antenna having an electrode for detecting the ground voltage and transmitting/receiving the radio wave, i.e., providing an antenna also serving as a detection electrode. CONSTITUTION: In an antenna 7, a voltage (e) proportional to the ground voltage V of a bus 10 is detected at an electrode 70 and inputted through an LPF 75 to a phase detecting section 3. The phase detecting section 3 detects the phase difference between the voltage (e) and a current detected by an AC unit and phase difference information is stored in a memory section. When a call command from the ground side is received at the electrode 70 of the antenna 7, it is received at a high voltage receiving section 6 through a BPF 74 while being demodulated. The call command is fed to the memory section from where phase difference information is delivered to a high voltage transmitting section 5. The phase difference information is modulated at the high voltage transmitting section 5 and delivered to the antenna 7 thence transmitted to the ground side.  Since the electrode 70 is fixed to only one point of the antenna 7, the phase detector is simplified and the price is lowered.

Abstract: PURPOSE:To eliminate the peeling of a film which contains a high-melting point metal from a second silicon film by forming a silicide of the high-melting point metal between the two films. CONSTITUTION:An insulating film, a first silicon film 13 containing impurities, and a second silicon film 14 are successively formed on a semiconductor substrate 11. Then a film 15 containing a high-melting point metal (tungsten) is formed on the film 14 and a silicide 20 of the high-melting point metal is formed between the films 14 and 15. Since a P diffusion process to be performed in an atmosphere containing P is not performed on the poly-Si film 14 which is the second silicon film, an oxide film is hardly formed on the surface of the film 14. Therefore, peeling of the film 15 containing the high-melting point metal from the silicon film 14 can be prevented.
