Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a solenoid valve driving device which can detect the abnormality of a current supply passage even though a capacitor for supplying peak current to the solenoid coil of a solenoid valve is so formed that it is connected to the current supply passage to the solenoid coil only when the solenoid valve is started to be opened and driven.

Inventor: ADACHI TATSUHIKO
IPC: C23C28/04
Filed: 1994-11-22
Abstract: PURPOSE: To obtain spherical particles having dense and thick titanium oxide films which are suitable as a spacer for a liquid crystal display device by forming a titanium oxide film on the surface of the spherical particle in a dispersion liquid of spherical particles of metal oxide, separating the particles from the dispersion liquid and subjecting the particles to specified treatment. CONSTITUTION: (1) Spherical particles of metal oxide are dispersed in an alcohol solvent essentially comprising medium alcohol. (2) An alkali soln. is added to the obtd. dispersion liquid to activate the surface of particles. (3) A titanium oxide TiO2 film is formed on the particle surface. In the process (3), the titanium oxide film is formed on the spherical particle by hydrolysis of titanium alkoxide or partial hydrolyzed material in the dispersion liquid of the metal oxide spherical particles and by dehydration and condensation. Then the spherical particles are separated from the dispersion liquid, dispersed in a neutral water, and subjected to heat treatment. Then the particles are heat treated in a dry state.  Further, the spherical particles with titanium oxide films obtd. in the process (3) are used as the starting material and the processes (1), (2), (3) are repeated once or more times to obtain the objective particles.

Title: Production of electrolytic silver powder
Inventor: YOSHITAKE MASAYOSHI
IPC: B22F9/26
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To obtain powder silver with which flocculation hardly arises by immersing electrolytic silver powder into an aq. soln. contg. the org. acid salt of higher aliphat. amine and drying this powder after dehydrating. SOLUTION: The silver powder is immersed into the aq. soln. contg. 20 to 5000ppm salt consisting of aliphat. monoamie or diamine having 12 to 22C aliphat. hydrocarbon, mono- or dicarboxylic acid having 7 to 8C arom. hydrocarbon group or its amine or carboxylic acid. The salt forms a film on the silver surface. This film is made into a water repellent protective film by drying. The protective film is stable and extremely thin and does not adversely affect sintering, thereby preventing the particle growth of the silver powder. The effect of the surface treatment is little and the powder is liable to flocculate if the content is lower than 20ppm. The performance as a metallic graphite brush is adversely affected if the content is higher than 5000ppm.  The electrolytic silver powder maintains the conventional powder characteristics and obviates the occurrence of the flocculation even after six months.

Title: Square matrix parallel calculating device
Inventor: FURUYUI YOSHIHIRO
IPC: G06F15/80
Filed: 1989-11-06
Abstract: PURPOSE:To execute high-speed processing by constituting a basic arithmetic unit with a multiplier and an adder and an internal register, and providing two inputs and one output. CONSTITUTION:Respective basic arithmetic units 1 execute calculation by the three data of an input data from the basic arithmetic unit 1 of the last row (an input data from a column data memory 3 for first row), an input data from a row data memory 2, and a data stored in an internal register 7, and outputs the result to the input of the basic arithmetic unit 1 of the next row (the input of the column data memory 3 for nth row). By executing this opera tion in several steps parallelly with the respective basic arithmetic processing unit, the calculation of a matrix given to the data memory is executed. Thus, the number of input/output ports and the number of signal lines for data are reduced to half of conventional devices, mounting becomes easy, and an efficient parallel processing becomes possible.

Title: Hoist-up control method of hoist device
Inventor: OSANAI TAKESHI
IPC: B66D1/54
Filed: 1994-11-24
Abstract: PURPOSE: To prevent the free falling of a suspension load at the time of upper limit switch action and in addition realize safety and long life by making the lock time of a hoisting motor minimum by cutting off the electric current of the hoisting motor when the detection value of the electric current of the hoisting motor has surpassed an over current limit value. CONSTITUTION: When the operation rod of an upper limit switch LS is operated by means of a hook block due to overwinding up during winding up action, the upper limit switch LS is actuated. At this time, the electric current value of a hoisting motor HM is compared with an current limit setting value previously set, and in the case of being less than the setting value, the action confirmation of the limit switch LS is returned, and in the case of being more than the setting value, the electric current of the hoisting motor HM is cut off. So long as the hoisting motor HM is not locked, the electric current of the hoisting motor HM is not cut off, so the danger of the free falling of a suspension load due to the action delay of a brake is not generated at all. Also, the extension of the longevity of the hoisting motor HM and the brake is realized.

Title: Electronic watch
Inventor: KOIKE KUNIO
IPC: G04C3/14
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To compatibly generate a confirmation sound at an optional timing without disturbing the operation of an analog watch by outputting a part of sound generation signal in a time position adjacent to a fixed pattern pulse when the fixed pattern pulse is superposed on the sound signal in time. SOLUTION: When measurement is started/stopped in stopwatch mode, a fixed pattern pulse is supplied from a motor driver 18 to the stepping motor of a display pointer 17, and a sound generation signal is supplied from a sound generation control circuit 24 to a sound generating means 23. When the timing of generating the fixed pattern pulse comes during the generation of a confirmation sound, generation and output of the sound generation signal are stopped, and the fixed pattern pulse is outputted during it. Thereafter, non-output part of the sound generating signal is again generated and outputted. Thus, although the sound generation signal is interrupted, for example, by about 4ms, this interruption is so slight that it can not be sensed by a person, and it never gives a sense of incompatibility or discredit to a user.

In this manner, a stress tending to bend to the side of a surface S2 is operated at the first, third, fifth,... sectional layers, and a stress tending to bend to the side S1 is operated at the second, fourth, sixth,... sectional layers. As a result, an internal stress is cancelled as a whole to mold a molded form 20 having a small strain.
