Title: Dry etching method
IPC: H01L21/027
Filed: 1992-03-28
Abstract: PURPOSE:To improve mask-selectivity of a lower layer resist layer against a mask at the time of etching and to prevent resticking of sputter on a base material layer containing Cu, relating to a three-layer resist process. CONSTITUTION:A lower layer resist layer 3 on an Al-1% Si-0.5% Cu layer 2 is etched with HI/O2 mixture gas. I(iodine) is hard to chemically react with Si. Since Clx which is an etching reactive product can be used as a side wall protective film 6, irradiative ion energy required for anisotropic working is reduced. As a result, the selectivity against an SOG pattern 4a which is an etching mask improves. This is also effective when a base material layer is a Cu layer. In short, by overetching a lower resist layer with gas group containing HI while a wafer is heated, the Cu sputtered can be removed in the form of Cu2I2, thus, particle contamination is prevented.

Title: Method for opening and closing roll of tension leveller
Inventor: SATO SUSUMU
IPC: B21D1/05
Filed: 1990-04-18
Abstract: PURPOSE:To decrease the defectively corrected part and to improve the yield by making each roll to open or close successively at every time when the arbitrary one point of the metallic strip passing through the tension leveller passes through each roll. CONSTITUTION:Because the connecting part W to connect the metallic strip 5 with the metallic strip 5 is connected in lapped state of the metallic strip with the metallic strip in up and down, so it is easily detected with the detector. The connected part is detected before entering into the tension leveller, the time from the detected time till the time reaching to each roll of the tension leveller of the arbitrary one point in the forward direction of this connecting part is calculated with the computing element, the roll is opened from the entrance side of the tension leveller one by one based on the calculated time. And the time from the detected time till the time reaching to the each roll of the tension leveller of the arbitrary point in the backward direction of this connecting part is calculated with the computing element, the roll is closed from the entrance side of the tension leveller one by one based on the above calculated time. Therefore, the defectively corrected part of the steel strip is decreased and the yield is improved and also the working rate is improved.

Title: Method and apparatus for continuous casting
Inventor: KAZAMA KUNIYOSHI
IPC: B22D11/06
Filed: 1985-05-14
Abstract: PURPOSE:To exchange rolles without interrupting casting and to improve productivity by pressing the fresh mold rolls of the same diameter to the body ends of a mold roll pair in continuous casting and moving the rolls in the roll axial line direction while rotating both rolls at a uniform speed. CONSTITUTION:A pinion 11 of a splined shaft 8 rotated by a motor M2 is connected to a gear 13 which rotates the mold rolls 1 supported by support rolls 15. The molten metal in a barrel 4 is thus continuously cast 5. The fresh mold rolls 12 of the same diameter are imposed on the rolls 15 and a gear 14 is connected to a pinion 10. A clutch 6 is engaged to rotate both rolls 1, 12 in contact with each other at the uniform speed thereby moving the rolls in the roll axial line direction. A driving motor M1 is started to continue the continuous casting. The clutch 6 is disengaged and the stopped mold rolls 1 are taken out. The rolls are exchanged without interrupting the casting, by which the production efficiency is improved. A moving belt may be used for one of the rolls 1.

IPC: H04N7/16
Filed: 1985-05-16
Abstract: PURPOSE:To display a picture which is able to be recognized in some degree before completing the receiving of picture information of one picture display by counting and arranging in another sequence the number of display dots at the picture information in a line or in a row, sending in order from the picture information having larger number of the display dots in a transmission side, and in such a case, adding position information to the picture information in the line or in the row.

To the composite circuit 14, a line address from the readout address generating part 13 is added and the line address is added to the forefront of the picture information in each line as the position information. The picture information received at a receiving part 4 is written to a buffer memory 6 with a clock (b), a row address signal (c) and a line address signal (d). therefore, the write of the picture information received is performed at a prescribed address in the buffer memory 6 even when the picture information is transmitted in the order of the larger number of the display dots not in the order of a scanning.

Abstract: PROBLEM TO BE SOLVED: To stabilize a connection characteristic by rivet-caulking the bend margin section of a tab terminal to a bus bar, and laser-welding the bend margin section to the bus bar at positions different from rivet caulking. SOLUTION: Rivet holes 4c, 4d are bored on the bend margin section 4b of a tab terminal 4a and a separate bus bar 4 respectively, and the bend margin section 4b of the tab terminal 4a is mounted on the bus bar 4, so that the rivet holes 4c, 4d match with each other. The bend margin section 4b is rivet-caulked to the bus bar 4 by a rivet 6 inserted into the rivet holes 4c, 4d. The bend margin section 4b of the tab terminal 4a is connected to the bus bar 4, by laser-welding (a) at positions different from rivet caulking. The bend margin section 4b is rivet-caulked to the bus bar 4, and the dispersion of connection strength is reduced. Since the rivet 6 is laser-welded, specially ordered rivet is not required, and the cost can be reduced.

Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for adjusting a bias current of a SQUID (superconducting quantum interference device) which can automatically and appropriately adjust the bias current in a short time. SOLUTION: A sine wave current of, e.g. 40 kHz is sent to a coil 12, thereby generating a magnetic field to a SQUID 10. An amplitude of the magnetic field is made a half cycle of a magnetic field-voltage characteristic. A voltage generated from the SQUID at this time is filtered by a filter 14 to extract 40 kHz and 80 kHz components. The extracted signal components are rectified by a rectifier 15 and converted to a d.c. voltage to obtain a maximum value. A bias current is adjusted to obtain the maximum value.

Filed: 1995-04-27
Abstract: PURPOSE: To provide an extremely small high-accuracy acceleration sensor by forming an optical wave guide on a cantilever formed on a silicone wafer, and detecting acceleration from the change of the refraction factor of the optical wave guide caused by the acceleration. CONSTITUTION: An optical wave guide 5 is formed on the silicon oxide film 2 of a cantilever 3 formed on a silicone wafer 1 and having a cantilever structure. A wire 7 is connected to an upper electrode 6, and a wire 9 is connected to a lower electrode. When the deformation of the cantilever 3 caused by acceleration is detected as the change of the refraction factor of the optical wave guide 5, acceleration is detected. Light is fed to one end of the optical wave guide 5, the change of the light output outputted at the other end is captured, and acceleration can be measured. Since the light output can be largely changed, a bridge circuit, required when a piezoelectric resistor is used, is not required. Since light is utilized, there is no effect of noises from the outside.
