Title: Phase control circuit
Inventor: AZUMA KUNIHIKO
IPC: H03C3/00
Filed: 1994-03-24
Abstract: PURPOSE:To suppress the amplitude variance due to variable control of the phase by setting the current supply capability of three transistors TRs constituting a differential circuit to a prescribed multiple of that of the other TRs to cancel the amplitude variance. CONSTITUTION:The amplitude variance is dependent upon the emitter area ratio; and if the emitter area ratio A is set to 2<1/2>+1 in accordance with the operation result, the amplitude variation is reduced to about 0.2 or smaller. Consequently, differential circuits 3 and 4 are added to cancel the amplitude variance accompanied with phases of output currents of differential circuits 1 and 2 constituting the multiplication circuit of a phase control circuit, thus performing the amplitude compensation. At this time, ratios of emitter areas of TRS Q11, Q21, Q31, and Q41 of differential circuits 1 to 4 to those of Q12, Q22, Q32, and Q42 are set to 2(A=2) or 3 (A=3) to suppress the amplitude variance to about 1.05-fold logical value. Thus, differential circuits for compensation where emitter area ratios, namely, the current supply capability is set to a prescribed multiple are added to suppress the amplitude variation.

Title: Semiconductor laser device
Inventor: TATENO KIMIO
IPC: H01S5/068
Filed: 1985-03-20
Abstract: PURPOSE:To obtain a semiconductor laser device, whereby an imaging spot thereof is not shifted even on a temperature change, by fixing an oscillation wavelength. CONSTITUTION:Interference fringes 8 are captured by a photodetector 6 to which a pin hole 9 is formed. When the temperature of a semiconductor laser 1 changes and an oscillation wavelength slightly alters, interference fringes are shifted slightly so far as the optical path difference of an interferometer does not take zero, and light intensity received by the pin hole 9 varies. The oscillation wavelength lengthens in general when the driving currents of the semiconductor laser augment and shortens when the driving currents reduce. Accordingly, a servo circuit altering the driving currents of the semiconductor laser in the direction that the change of the amount of light detected by the photodetector 6 is constituted, thus eliminating the variation of the interference fringes, then fixing the oscillation wavelength of the semiconductor laser.

Title: Wire for tig welding of austenitic stainless steel for ultra-high vacuum equipment
Inventor: MAEDA TATSUO
IPC: B23K9/23
Filed: 1990-03-06
Abstract: PURPOSE:To decrease released gases by limiting the contents of S and O among the components incorporated into the wire consisting of an austenitic stainless steel to respectively specific concns. or below. CONSTITUTION:The content of the S among the components incorporated into the wire 4 consisting of the austenitic stainless steel is limited to <=0.010wt.% and the content of the O to <=30ppm. The amt. of the gaseous H2 to be released decreases if the amt. of oxide inclusions is decreased by lowering the content of the O. The amt. of the gaseous H2 to be released decreases if sulfide decreases and, therefore, the content of the S is required to be set low. The above-mentioned theme is attained by using the wire which is lower in oxygen content than the stainless steel for ultra-high vacuum equipment and is low in the content of the S. Since the inclusions in a weld metal are decreased in this way, the gases to be released from the weld metal are extremely decreased and the remarkable improvement in the performance of the vacuum equipment is made.
