Abstract: PURPOSE: To improve the welding quality and welding efficiency, by measuring the time from  start of power supply till the change in resistance between electrodes becomes the maximum,  and adjusting the current standard so that the measured time may be equal to the set value.   
     CONSTITUTION: A current reference value 134 is outputted from a current setting part 33 and a  current standard generating part 34, and the root mean square value determined through current  transformer 36, current detecting part 37, and effective value calculating part 38 is compared  with the reference value in a comparator 39, and the set current is designed to flow into members  13a, 13b to be welded by way of phase control part 40 and thyristor 31. The weld time indicating  the maximum resistance is measured through maximum voltage and current detecting parts 44,  45, resistance calculating part 46, and resistance change detecting part 47, and is judged by a  counter 48. The average of n times is taken by memory part 49 and reference value calculating  part 50, and the reference value is calculated, and set in a reference value setting part 51. The  counting 148 by the counter 48 and the reference value 151 are compared with each other in the  comparator 52, and the deviation is inputted in a current correction rate detecting part 53, and  the reference value 134 is automatically corrected by the current correction rate 153, so that the  welding current may be corrected.

Title: Position detection method for mobile object
Inventor: SONE FUMIKI
IPC: G01V3/12
Filed: 1980-03-06
Abstract: PURPOSE:To perform highly reliable position detection with a comparatively fewer number of pair lines by constituting in such a manner that the number of pair lines where an inductive radio line is open may always be fixed. CONSTITUTION:When an inductive radio line 6 is composed of five sets of pair lines 51-5n having an open part L and a closed part C, these pair lines are mutually overlaid in a whole one body. Speaking of the inductive radio line 6 as a whole, the number of pair lines having an open part L in each section Z1-Zn is always fixed such as two sets and a signal from a mobile object antenna is always received by two sets of pair lines. Further, if the number of pair lines which show a change in the condition of the open part L and the closed part C is always set at two sets at a boundary point between Z1-Zn of each section, it comes that three sets of pair lines undertake a job of reception when the mobile object is located at a boundary point in each section. Under this constitution, a position detection device identifies a reception circuit and monitors the number of reception circuits, thus detecting a fault. Therefore, it is possible to improve the reliability with a fewer number of pair lines.

Title: Formation of bpsg film
Inventor: YU KEISHIYOKU
IPC: C03C27/04
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To obtain a formation method in which a wet-etching-rate ratio is lowered while the flattening rate of a BPSG film is raised by a method wherein, after the inside temperature of a furnace is quenched, a wafer is unloaded, the surface part of the flattened BPSG film is set as a quenched region and the inside is set as a gradually cooled region. SOLUTION: The surface part of a BPSG film 3A forms a quenched region in which a film structure is maintained as it is at a reflow temperature. On the other hand, the inside of the BPSG film 3A forms a gradually cooled region 13 in which a substance inside the film is cooled gradually at the reflow temperature so as to be crystallized. The contractive force of the gradually cooled region 13 in the BPSG film 3A having such a structure is relatively larger than the contactive force of a quenched region A, and it is possible to restrain a crystal precipitate from being generated on the surface of the BPSG film 3A in the quenched region A due to a compressive stress.

Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To reduce pressure of a contact surface between a dynamic pressure shaft and a dynamic pressure sleeve and reduce start a friction torque by providing a magnetic compensation means which acts in the direction in which gravity to be applied to a rotary mirror and other rotary member side is reduced. SOLUTION: A dynamic pressure air bearing part consisting of a dynamic pressure shaft 7 and a dynamic pressure sleeve 6 supports a rotary mirror 11 and other rotary member rotatably. At this time, a magnetic compensation means is constituted in such a manner that a stator core 2 is deflected downward by a predetermined amount for a central shaft of the rotary member. For this reason, magnetic attracting force F which acts on a rotor magnet 4 is distributed like a profile H to generate a magnetic attracting force which is in the reverse direction to the direction of gravity G as a total sum, and the weight of the rotary members such as the dynamic pressure shaft 7, the rotary mirror 11, the rotor magnet 4, etc., is subtracted due to this magnetic attracting force.  Consequently, it is possible to reduce pressure of a contact surface between the dynamic pressure shaft 7 and the dynamic pressure sleeve 6 at the time of start and stop to eliminate the malfunction at the time of start and stop.
