Title: Oscillation-preventable digital vtr and control method and system therefor
Inventor: OTA HIROSHI
IPC: G11B20/10
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of oscillation even at the time of connecting digital interface input/output terminals and line input/output terminals of two digital video tape recorders respectively to each other. SOLUTION: Dubbing is performed by recording with the 1st digital video tape recorder 20 and reproducing with the 2nd digital video tape recorder 30. The digital interface input/output terminals are connected to each other, while the line output terminal 22 of the 1st digital video tape recorder 20 is connected with the line input terminal 31 of the 2nd digital video tape recorder 30. In the 2nd digital video tape recorder 30, the line input terminal 31 is set to be active, and when the inside operating state becomes a stop mode, the digital interface input/output terminal 33 is set to the output inhibit state by cooperation of a mode control part and a digital interface input/output control part of the 2nd digital video tape recorder 30 to cut off a signal loop to prevent the oscillation.

Title: Direction finder
Inventor: HAYAMA KATSUSHI
IPC: G01S3/14
Filed: 1985-03-29
Abstract: PURPOSE:To discriminate the quality of a signal to obtain easily a reliable azimuthal angle by providing a counting circuit which counts the comparison result of a comparator at each quantization time and discriminating whether direction waveform data is good or not in accordance with the counted result. CONSTITUTION:If a direction waveform data string is obtained from an A/D converting circuit 12 as shown in the figure, the second counter 16 counts the number of sampling signals of the direction waveform data string during periods T2, T4, and T6 when SD>=Sref is true. And the first counter 15 counts the number of sampling signals of the direction waveform data string during periods T1, T3, T5, and T7 when SD<Sref is true. In this case, a discriminating circuit 17 discriminates the signal SD as a defective signal in accordance with correlations of these counted values. That is, when the signal is discriminated as an indefectible signal, the waveform is observed to obtain easily a reliable azimuthal angle.

Title: Dry etching method
Inventor: KADOMURA SHINGO
IPC: H01L21/3065
Filed: 1989-03-17
Abstract: PURPOSE:To prevent the readhered product of aluminum from adhering to a sidewall to be etched by switching etching gas to aluminum etching gas immediately before an aluminum or aluminum alloy film is exposed. CONSTITUTION:After a lower layer resist 5 is formed on an aluminum film 4, the resist 5 is coated with SOG to form an intermediate layer 6, and an upper layer resist 7 is further formed. Then, it is exposed and developed, and the layer 6 is patterned by RIE using oxygen as etching gas with the resist 7 as a mask. Subsequently, with the layer 6 as a mask it is etched by RIE with O2 as etching gas. Then, the etching gas is switched to boron trichloride gas of aluminum etching gas, and it is further etched to remove the resist 5 of the side of the other intermediate layer (mask) 6 by etching. Since the gas is switched from the O2 gas to the BCl2 gas, no Al2O3 (readhered product) is not generated.

Abstract: PROBLEM TO BE SOLVED: To improve heat-resistant property and resistance to heat shock, and reduce the manufacturing cost, by constituting a protecting tube of sensor part of a level position-measuring level sensor in a mold of a component of SIALON/BN. SOLUTION: The protecting tube for protecting the sensor part of a level position-measuring level sensor in a casting mold from heat and splash is formed out of a material composed of SIALON/BN. The SIALON is a β' type, Z value in a chemical formula Si6-z Alz Oz N8-z is 0.5-3.0 and BN is contained by 0.5-40wt.%. In order to mold the tube, generally, a uniaxial molding method or a hydrostatic pressure molding method is used. In some cases, the material may be slip cast without being granulated. The molded body is dried and binders are evaporated/removed (degreased). Thereafter, the molded body is sintered through treatments. In the case of sintering with a normal pressure, e.g. the molded body is preferably sintered in an ambience of nitrogen at 1650-1800 deg.C for a holding time of 5-10 hours. The holding time is shortened as the temperature is higher.

Abstract: PROBLEM TO BE SOLVED: To safely recover a battery component, without decomposition or damages by taking out an electrolyte in a battery housing, or a solvent in the electrolyte, to lower the ion conductivity between negative and positive electrodes, and then opening the battery housing. SOLUTION: A space is formed which is composed of part of the housing external wall of the sealded type battery 100, an electrolyte extracting tube 103, and a storage tank 104. A system inside is decompressed by an exhausting means 105, connected to the tank 104 via an exhaust tube 107, to reduce pressure in the space to be lower than that in the inside of the battery 100. A safety valve 102 attached to the battery 100 is opened, and an electrolyte in the inside of the battery 100 is extracted into the tank 104 via the extracting tube 103 to be recovered. This causes the absence of the electrolyte between positive and negative electrodes in the battery 100 to reduce the ion conductivity.  Then, a leak valve 113 is actuated to introduce air and nitrogen, etc., into the system, and the battery housing is opened under a condition, such that the ion conductivity between the positive and negative electrodes is reduced, thereby recovering a content member.

Abstract: PROBLEM TO BE SOLVED: To facilitate mechanical machining of a cam so as to provide a lightweight inexpensive can shaft by molding a cam by means of aluminum alloy die casting and connecting the cam to the side face of a steel pipe by means of soldering. SOLUTION: A cam shaft 1 is molded of an aluminum alloy by means of die casting, while a steel pipe is machined so as to be formed into a shaft 2, and the cam 1 and the shaft 2 are dipped into a solder bath and are impressed with ultrasonic wave, so that zinc solder layers are formed on the surfaces of the cam 1 and the shaft 2. A fitting hole 1a in the cam 1 on which the solder layer is formed is force fitted to a fitting part 2a in the shaft 2 on which the solder layer is formed as well by means of pressing. Subsequently, the force fitted part is heated by means of a burner or high frequency induction heating until a temperature of the part reaches a temperature high enough to melt the solder layer, and then, ultrasonic wave is impressed.  Consequently, an oxidation coating on the solder surface is broken and the solder is mixed sufficiently, while fluidity of the solder is increased, so that a solder layer with a uniform thickness is formed in a clearance between the cam 1 and the shaft 2.

Title: Turbulent flow generator
Inventor: ADACHI TAKESHI
IPC: G01M10/00
Filed: 1981-04-30
Abstract: PURPOSE:To produce a turbulent flow having the fluctuation component of a high flowing speed in the flowing direction and the turbulent flow caused centering on said fluctuation component, by rocking the adjacent ones among plural diaphragms in the opposite direction to each other. CONSTITUTION:A blow-off nozzle 1 of a wind tunnel opens to the air. A diaphragm 3 is oblong and held horizontally to a framework 2 via a shaft piercing through its center to be rotated turnedfreely around the shaft core. A gear 4 having a pitch circle equal to the space between shafts is attached to an end of the diaphragm 3 respectively. These gears 4 mesh with each other. The rotation of a motor 7 is transmitted to the gear 4 via a V-belt 6 and a pulley 5. When the fluctuation of the wind velocity is applied, the motor 7 is driven to rotate the gear 4. As a result, the diaphragms 3 rotate in the opposite direction to each other. The wind velocity varies in a range of Va-Vc for the wind of the downstream side of the nozzle 1. Then an eddy is produced by the exfoliation of the wind that hits the diaphragm 3, and as a result the fluctuation is caused to produce a turbulent flow which is close to the natural one.
