Title: Production of sputtering target for optical recording
Inventor: IWAMOTO TETSUSHI
IPC: C23C14/34
Filed: 1985-11-13
Abstract: PURPOSE:To stabilize sputtering conditions with a uniform compsn. having a high density and to improve productivity by mixing titanium, etc., with selenium, bringing the same into reaction by heating in a vacuum or inert gaseous atmosphere, adding tellurium to the mixture and pulverizing the mixture then molding the powder under pressurization. CONSTITUTION:The sputtering target for optical recording is obtd. by mixing >=1 kinds of metals such as titanium and silver with a selenium alloy, bringing the mixture into reaction by heating in the vacuum or inert gaseous atmosphere, adding a tellurium alloy to the mixture, pulverizing and mixing the same in the nonoxidative atmosphere and subjecting the mixture to molding under pressurization then to cutting and finishing. These materials are mixed at ratios of 60-100% tellurium, <=30% selenium and <=20% >=1 kinds of metals such as titanium, silver, arsenic and lead. The uniform compsn. approximately equal to the theoretical density is thus obtd. by pulverizing and mixing. The inter- particle binding power is increased by the improvement of sinterability, by which the sputtering conditions are stabilized. The productivity is improved by the continuous sputtering.

Inventor: OTA TAKASHI
IPC: B41J2/295
Filed: 1989-09-27
Abstract: PURPOSE:To lengthen life of a printing hammer by a method wherein a T-shaped and a U-shaped hinges have a thin wall part causing bend deformation and a thick wall part on its both ends, thickness is varies graudally from the thin wall part to the thick wall part, and the thick wall part is connected to an arm, a piezoelectric element, and a fixing component. CONSTITUTION:For a U-shaped hinge, thick wall parts 2, 3 thicker than a thin wall part 1 are connected to both ends of the thin wall part 1 with a thin wall causing bend deformation so smoothly that the thickness varies gradually. The thick wall part 3 is connected to a piezoelectric element, and the thick wall part 6 is connected to an arm. Fixing and connection of the hinge are performed with the thick wall parts 2, 3, 5, 6. Since the connection is performed so smoothly that the thickness is not quickly varied from the thick wall part to the thin wall part, stress concentration is reduced. Consequently, long life is obtained against cyclic bending stress.

Title: Optical fiber liquid detecting sensor
Inventor: UCHINO NAOTAKA
IPC: G01M3/38
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To quickly detect liquid leak of a liquid oil, chemicals, and the like by forming a resin layer for coating an optical fiber out of a resin reducing its strength by contact with a liquid to be inspected. SOLUTION: The outer circumference of an optical fiber 11 is coated with a strength reducing resin layer, and two linear elastic bodies (coil springs) 13 in a state where a tension is applied, are contained inside the resin layer 12 (or outside) in parallel along the optical fiber 11 to form the optical fiber liquid detecting sensor 10. A long chain alkyl acrylate resin or the like is used for the strength reducing resin when the inspecting object is a liquid oil, a polyamide resin is used in the case of an acidic liquid, and a cellulose resin, a polyvinyl alcohol or the like is used in the case of common use for an acidic liquid and an alkaline liquid.  Though the optical fiber 11 is a straight line normally, the resin layer 12 starts immediately softening with adhering of gasoline or the like, and the elastic body 13 is contracted in accompaniment to the softening to curve the optical fiber 11 with a large curvature. Since a light transmision loss is quickly increased, and thereby, liquid leak can be detected.

Title: Semiconductor integrated circuit
Inventor: IWAHASHI HIROSHI
IPC: G11C11/417
Filed: 1988-10-07
Abstract: PURPOSE:To prevent malfunction due to a power source noise from occurring by applying control so as not to vary the level of output data when the pulse width of a pulse signal is smaller than prescribed length. CONSTITUTION:When the malfunction due to the power source noise occur in column and row address buffer circuits 12 and 13 at the time of outputting data from an output buffer circuit 23, a pulse signal generation circuit 25 generates the pulse signal similarly as when address input changes normally. Thereby, a memory cell array 18, a sense amplifier 21, and the output buffer circuit 23 start their operations, respectively. However, at this time, since the pulse width of the pulse signal generated at the circuit 25 is smaller than a regular pulse signal, a pulse width detection circuit 26 outputs no detecting signal, and a transmission control circuit 22 supplies no erroneous data in the amplifier 21 to the circuit 23. Therefore, the level of the data already outputted from the circuit 23 remains unchanged, which prevents the malfunction from occurring.

Title: Solder adhesion preventing equipment for retaining pawl
Inventor: TAKAYAMA KINJIRO
IPC: H05K3/34
Filed: 1991-09-04
Abstract: PURPOSE:To prevent solder from adhering to a retaining pawl, by retaining an object to be carried after the retaining pawl is coated with solution of mate rial having the surface tension decreasing action of solder and oxide reducing action of solder, and bringing the object to be carried with fused solder, in an automatic soldering equipment provided with a spray fluxer. CONSTITUTION:A retaining pawl 20 is carried by a conveying chain 15 of an automatic soldering equipment. When the pawl 20 passes the inside of a case 25 of a solution coating equipment 24 on the returning path, a retaining part 21 is coated, by a brush 28, with solution of material having surface tension decreasing action of solder and oxide reducing action of solder. On the proceeding path, the retaining pawl 20 retains a substrate and brings it into contact with fused solder in a solder tank. In this case the coating material on the retaining part 21 is fused by heat, and the oxide film of solder floating on the fused solder surface is reduced. The surface tension of the film is decreased and the film is pushed toward end portions. Thereby a state free from the oxide film is obtained, and nothing adheres to the retaining part 21, so that the retaining pawl 20 surely retains an object to be carried.

Filed: 1992-09-24
Abstract: PURPOSE:To obtain adequately efficient wash effects as desired, if an object to be washed which is present at a fine interval by irradiating water after treatment for reducing impurities such as inorganics/organics and bacteria with far infrared beam having strong energy within a range of specific wavelength. CONSTITUTION:An object to be washed 5 such as tungsten filament is deposited in a wash chamber 2, and purified water 2 is allowed to circulate repeatedly through the entire device by a water circulator 3. A far infrared beam radiation 7 is arranged at some part of a far infrared beam emission chamber 1 to heat water routinely to a specified temperature. In addition, a far infrared beam having a strong energy ranging from 2 to 40mum of wavelength is released constantly from the far infrared beam radiation 7. Consequently, the purified water 6 to which the far infrared beam is emitted in the emission chamber 1, develops a spontaneous phenomenon that the size of a molecular group diminishes due to the stimulation of vibration and rotation. Thus the molecules of the purified water are allowed to penetrate easily into the space of the fine part of an object to be washed, so that the increased enhancement of wash effects is achieved.
