Title: Dry etching of laminated wiring
Inventor: AKIBA NAMISATO
IPC: H01L23/52
Filed: 1994-03-25
Abstract: PURPOSE:To perform an anisotropic etching on a laminated wiring, which has an Al metal layer formed on a W layer and is superior in migration resistance, using an inorganic material mask without being accompanied by residues and the generation of contamination of particles. CONSTITUTION:An Al metal layer 5 is etched with sulfur chloride gas and after this, a high-melting point metal layer 4 is patterned substituting the sulfur chloride gas for sulfur fluoride gas. N gas, such as N2 gas, may be added to the sulfur fluoride gas. At this time, as sidewall protective films 10, which consist of sulfur or polythiazyl, are etched while being formed, the side surfaces of the patterned layer 4 can be protected from the attack of radicals, the generation of the side etchings of the layer 4 is prevented. When a substrate to be etched is heated after the etching ends, the films 10 are sublimed and can be removed without remaining traces of the films 10. As a result, there is no possibility of contamination by particles.

Title: Formation of thin film and device therefor
Inventor: UCHIDA HIROYUKI
IPC: H01L31/04
Filed: 1986-03-13
Abstract: PURPOSE:To enable a thin film of high quality without plasma damage to be uniformly formed over a large area, by forming excited hydrogen atoms uniform over a large area and performing radical reaction of the excited hydrogen atoms with the raw material gas. CONSTITUTION:Hydrogen molecules 11 are decomposed into hydrogen atoms 13 in excited states by catalyst reaction on the surface of a metallic heater 12 heated at high temperature. Then, while a mixing gas involving molecules containing silicon atoms or germanium ones is made to serve as a raw material gas 15, the hydrogen atoms 13 in excited states are made to collide with the raw material gas molecules 15 to decompose 16 the raw material gas molecules 15 by radical reaction so that a thin film 18 is formed of the decomposed products 17 at low temperature on the substrate 19. Hence, a thin film of high quality without plasma damage can be formed uniformly over a large area.

Title: Method of welding solenoid tube
Inventor: ITO NAGAKATSU
IPC: H01F7/06
Filed: 1987-03-11
Abstract: PURPOSE:To reduce the occurrence of cracks in welded parts and to decrease residual stress after welding to a large extent, in a welding method of a solenoid tube, by which the tube and a member that is coupled into the end part of the tube are welded, by providing a part for absorbing stress at the adjacent part of the welded part. CONSTITUTION:An annular recess part 4 is formed at a position neighboring a small diameter part 3 at the outer surface of a fixed iron core 2 beforehand. A length L1 of a tube 1 in the axial direction from an end surface 5 of the small diameter part 5 to an end surface 6 of the recess part 4 is determined by an axial direction L2 of a welded part 7, which appears at the outer surface of the fixed iron core 2. The length L1 is determined so that a distance 1 from the end of the recess part at a welded part 7, which appears at the outer surface of the fixed iron core 2 after the welding, to the end surface 6 of the recess part 4 becomes 0<=L<= 3t, where (t) is the thickness of the tube 1. A depth W of the recess part 4 is made to be W>=1/3t. A part 8, which is surrounded by the welded part 7 and the end surface 6 of the recess part 4, absorbes stress when the welded part 7 is hardened, allows the contraction of the welded part 7 and prevents the yield of residual stress.

Filed: 1988-03-11
Abstract: PURPOSE:To attain the use of an electronic view finder excepting that an object is dark and located at a remote place by excluding an infrared-ray cut filter from an optical path or energizing a lighting means. CONSTITUTION:When the lightness of an object measured by an external light type photometric element 14 is insufficient for the application of an electronic view finder, the infrared-ray cut filter 9 is excluded from an optical path and an auxiliary lighting device 12 is energized so as to make an output of a CCD area sensor 4 proper. In the case of the strobo using mode, the infrared-ray cut filter 9 is excluded from the optical path and the auxiliary lighting device 12, the electronic shutter and an aperture 2 or the like are adjusted to make the output of the sensor 4 proper. Thus, the use of the electronic view finder is attained excepting that the object is dark and placed at a remote location in the non-strobo state and a large and expensive optical finder is not required.

Filed: 1982-04-05
Abstract: PURPOSE:To reduce a control error, by compensating a period value of a pulse signal by its preceding or following normal period value, and using it as a flow rate operating signal, in case when said period value changes suddenly. CONSTITUTION:In a period detecting circuit 11 of a signal processing circuit 10, a period value Ta of a pulse wave from a Karman sensor 2 is detected. In a comparing circuit 12, the value which multiplies a period value Ta by a constant C is compared with the preceding period value stored already in a storing circuit 14 as to whether its correction is necessary or not. In a correcting circuit 13, in cooperation with the comparing circuit 12, the period value related to an excessive variation is compenusated in a prescribed ratio in relation to the preceding period value and is corrected so as to approach a normal period value, thereby obtaining a flow rate signal. By using this signal, the quantity of fuel to be jetted is controlled in a controlling circuit 20. Therefore, a control error can be reduced.

When the signal (d) changes from 0 to 1, the output D is charged by TR1. The voltage of output D is increased by the capacity C1 after a delay time given by the circuit 50 and reaches the voltage VC or higher. Thus the output DOUT of the output-stage buffer 40 is set quickly at 1 level.

Title: Emergency release device for car constant speed running device
Inventor: DAISHIN MASAAKI
IPC: B60W10/184
Filed: 1978-05-15
Abstract: PURPOSE: To sharply shorten an idle-running distance and to improve the safety at a time when running at a constant speed, by releasing  a constant speed running action after detecting the motion of the foot in the case of such a emergency control that requires the faster motion of the foot in the pedal direction than a given value.  
     CONSTITUTION: Sensors 1 and 1' are located so that they can detect in order the movements of the feet stepping on the brake and pedal. When the feet move from a constant speed running condition, the sensor 1 works, and the condition is held by a hold circuit 2 and continues until a hold circuit 2' transmits an erasing signal by the use of the sensor 1'. When pulse rate of a pulse signal of a clock 3, which is input to a comparision decision circuit 4, is found to be less than a given value as a result of comparision with a standard pulse, it is decided that the extremely rapid movement of the feet is needed and an emergnecy control is required. A signal thus is transmitted to a switching circuit 6 to release the action of a constant speed running device 7.

Filed: 1987-03-12
Abstract: PURPOSE:To reduce readout errors by forming a thin metallic film as a reflecting film on a signal recording surface formed on a plastic substrate and by further forming a light shielding film on the reflecting film. CONSTITUTION:A signal recording surface 2 having a digital signal recorded by unevenness of 1,000Angstrom  depth is formed on polycarbonate substrate 1 and an Al reflecting film 3 of 450Angstrom thickness is formed on the surface 2.

The film 4 absorbs laser light reflected irregularly by the Al grain boundaries of the film 3 and shields light incident from the rear side of the resulting disk. Thus, the S/N ratio of laser light reflected by the signal recording surface is increased and signal readout errors are reduced.
