Title: Polishing method and polishing device
Inventor: SAITO TOSHIYA
IPC: B24B37/00
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To improve the stability of polishing speed of a polished film of a semiconductor wafer by stabilizing the rate of a chemical reaction during polishing operation by polishing the film in a temperature-controlled environment. SOLUTION: A semiconductor wafer 1 is picket up by vacuum chuck though the pipe 13 of a pressurizing head 6 and carried to a prescribed position above a turntable 3 in slurry 2 contained in a liquid both 10. Then the wafer 1 is immersed in the slurry 2 in the both 10 together with the head 6 by lowering the head 6. After immersion, the temperature of the slurry 2 in the both 10 is always detected by means of a temperature sensor 11 and the oxide film 16 of the wafer 1 is polished by pressing the wafer 1 against the polishing pad 4 of the turntable 3 by means of the head 6 wile both the turntable 3 and head 6 are rotated. During polishing, the temperature of a circulated solvent 22 is always adjusted by controlling a thermostat 14 by means of a temperature control section 17 based on the sensing results of the temperature sensor 11 which detects the temperature of the slurry 2.  Therefore, the polishing speed of the film 1c to be polished can be stabilized by stabilizing the speed of chemical reaction during polishing operation, because the speed of the highly temperature-dependent chemical reaction can be stabilized.

Title: Consumable electrode type arc welding source
Inventor: MOTOMIYA AKINORI
IPC: B23K9/173
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To exactly execute discrimination of a short-circuit period and arc period by generating the reference signal for judging the short-circuit or the arc based on the waveform itself of welding voltage detected with a welding voltage detecting part. SOLUTION: First, the welding output voltage is detected with the welding voltage detecting part 1 and a signal waveform are outputted. Next, this output signal is inputted in an AC coupling circuit part 2, the 0 V level of the signal is shifted and the signal waveform is outputted. Furthermore, the output signal of the AC coupling circuit part 2 is compared with the 0 V level in a short- circuit/arc discriminating part 5, the signal waveform is outputted. With the short-circuit/arc discriminating part 5, when the output signal of the AC coupling circuit part 2 is smaller than the 0 V level, it is discriminated as the short- circuit period and a short-circuit/arc control switching part 8 is connected to a short-circuit period control part 6.  When the output signal of the AC coupling circuit part 2 is larger than the 0 V level, it is discriminated as the arc period and the short-circuit/arc control switching part 8 is connected to an arc period control part 7.

Title: Information reproducing device
Inventor: SERITA HIROAKI
IPC: H04N9/87
Filed: 1982-06-23
Abstract: PURPOSE:To correct a chrominance signal component without using any delay line and to reproduce a chrominance signal of stable good quality by using two kinds of carrier which are reverse in-phase with each other, discriminating and controlling chrominance signal disorder, and applying one carrier to a modulator. CONSTITUTION:When the phase of a burst signal is normal, a discriminating circuit 56 generates no signal disorder detection signal. In this case, a switch circuit 66 selects and applies a carrier for a signal (R-Y) from an input terminal 66a to the modulator 61. Therefore, regarding the axis of modulation of a carrier for a signal (R-Y) and (B-Y) in case (B-Y) is at 0 degree, that of the carrier for the signal (R-Y) is at +90 degrees. When a VTR is set in still reproduction, fast-forwarding, or reverse feed playback operation, the disorder of a reproduced chrominance signal is caused and the phase of the burst component becomes unstable. In this case, the discriminating circuit 56 generates the signal disorder detection signal and the switch circuit 66 selects the carrier for the signal (R-Y) from its input terminal 66b, so that the axis of modulation of the modulator is inversed by 180 degrees.

Filed: 1989-04-27
Abstract: PURPOSE:To obtain accurate spectrum over wide wavelength range by making wavelengths deviate in a wavelength overlapped area so that the spectral waveforms may be the most similar and elongating and contracting the entire spectrum in accordance with the deviation of the wavelength. CONSTITUTION:A photodiode array 15 moves an optical system consisting of a collimator lens 12, a slit 13 and a concave diffraction grating 14 so that the spectra of plural wavelength areas whose parts are overlapped are obtained. A controller 17 fetches data from a memory 31 where each spectral data is stored and a wavelength correction means 32 makes the endpoint of one spectrum or the endpoints of both spectra deviate in a wavelength direction in both areas where the wavelengths of plural spectra are overlapped so that the waveforms of both spectra may become the most similar and distributes the deviation at the endpoint by taking the wavelength calibration point of the spectrum as reference. Then, the entire spectrum is elongated and contracted in the wavelength direction so that the wavelengths may be overlapped. The synthesized spectrum obtained by a spectral intensity correction means 33 is stored in the memory 31 and displayed on a display unit 18 if necessary.
