Title: Mold molding method and pattern plate
Inventor: KAWAMURA YASUTAROU
IPC: B22C15/28
Filed: 1979-05-08
Abstract: PURPOSE: To obtain the mold packed to even hardness and high density by passing compressed air through the material packed in the spacing formed by a molding plate with plural vent holes and a molding flask which is opened at top and bottom parts from above and exhausting the same at a deviated timing through said vent holes.  
     CONSTITUTION: Molding sand 46 is packed in the spacing formed by closing an on-off valve 17 and hermetically placing a molding falsk 18 on the top surface of a pattern plate 1. When compressed air is fed into the molding flask 18 from above, it passes through the inside of the sand 46 and first passes through the vent holes 9 of the concave pattern part 3 communicating with the outside air. It is then exhausted through a bent plug, cavity 6 and exhaust hole 12. When the valve 17 is next opened, the compressed air passes through the vent holes 10, 11 at the top surface of the pattern plate 2 on the side close to the feed position then through the vent plug, cavities 7, 8, exhaust holes 13, 14, pipings 15, 16 and valve 17, and is thereby exhausted. In this way, the sand 46 is densely and firmly deposited first on the pattern part 3, then on the 4, 5 surfaces.

Abstract: PURPOSE:To enhance the sensitivity and stability of a sensor, in a gas sensor using a semiconductor photocatalyst material having catalytic action by the irradiation of light as a gas responsive part and providing a light pervious electrode and a metal electrode to said part, by applying heat treatment to the metal electrode at a specific temp. CONSTITUTION:A Pt-layer 3 being an electrode is provided to the upper surface of a TiO2 layer 2 (photocatalyst material) being a N-type photoconductor and a Ti-layer 4 being an electrode is provided to the under surface thereof. The TiO2 layer 2 and the Ti-layer 4 are obtained by applying heat treatment to high purity Ti at 750-1,050 deg.C in an air atmosphere. By the high temp. heat treatment, the crystallinity of the TiO2 layer 2 is enhanced and the electron and hole formed in the TiO2 layer 2 is enhanced and the electron and hole formedin the TiO2 layer 2 are smoothly moved to the Ti-layer 4 to enhance the function of the photocatalyst material. At this time, the Pt-layer 3 is formed so as to have a porous light pervious structure and light is allowed to reach the TiO2 layer 2. Because the TiO2 layer 2 being the metal electrode is heat- treated, a sensor having high sensitivity and excellent selectivity is obtained.

Abstract: PURPOSE:To prevent a lamp current from going up due to a sodium leakage, by installing two electrodes set up at both sides of a light emitting tube and an electrically parallel short discharging gas in an outer tube, while interposing a fuse in part of a connection line. CONSTITUTION:Two electrodes set up at both sides of a light emitting tube 1 and a short discharging gap G are installed in an electrically parallel manner, while a fuse 10 to be fused down at more than the specified current value is interposed in part of a connection line connecting these electrode to an external circuit. When a sealed material inside the light emitting tube 1 gets leaked, discharge starting voltage in the gap G suddenly drops, and when such starting voltage comes into being lower than that in both electrodes of the light emitting tube 1, discharge occurs in the gap G such a current as being more than a lamp current flowing in time of discharging between both electrodes of the light emitting tube in a steady state is made to flow into a leading-in wire 12 and a support line 2. Therefore, with this current, the fuse 10 is fused down, cutting off the current flowing between both electrodes.

IPC: G03C1/00
Filed: 1988-03-10
Abstract: PURPOSE: To shorten the time necessary for use in the heat and curing cycles generated on an optical tool and to obtain the rapid production cycle time by generating the change of the photosensitivity of a photosensitive material in such a manner as to convert a unstable state into a stable state in response with the photosensitive material of the radiation unstable state in the two respective regions identified by the control patterns of chemical rays. CONSTITUTION: For example, this photoprinting consists of a photographic process which can be operated to the photosensitive material of a liquid photosensitive polymer. The photosensitive material in the unstable state like that of the liquid photosensitive polymer layer 14 is radiated by the patterns and quantity of the chemical rays controlled by flashing short chemical energy via the image of a light transparent medium, by which the patterns of the material in the stable state, i.e., the polymerized state are generated in the layers during the first radiation stage. Consequently, the two regions are formed as the material surface patterns of the unstable state and the stable state are formed in the layers. The solder mask coating patterns, etc., are formed by the surface pattern regions in the stable state. As a result, the rapid production speed is obtd. by simple equipment.

IPC: G06F12/12
Filed: 1987-03-11
Abstract: PURPOSE:To improve the hit ratio of a cache memory by designating an address that desires the inhibition of substitution and preventing the send-out of a neces sary block out of the cache memory. CONSTITUTION:When a substitution inhibiting address validity indicating signal (c) is set at '1', a higher rank address signal (e) sent from an address array 13 is compared with a substitution inhibiting area address (d) sent from a substitution inhibiting area indicating device 12 by comparators 161-164. If the coincidence is obtained between the signal (e) and the address (d), the relevant level is inhibited for substitution and the level number is encoded 17 and sent to a comparator 18. While a lower rank address (b) is sent to a substitution subject indicating device 14 and a substitution subject level (j) of a set corresponding to the address (b) is instructed together with the next substitution candidate (k). The level (j) is compared 18 with a substitution inhibiting level. When the coincidence is obtained from this comparison, a substitution subject level selection signal (l) of a substitution subject level selector 21 is inverted. Then a substitution level (m) is outputted as a substitution subject level.

Title: Synchronous induction motor of two or more stators
Inventor: SATAKE TOSHIHIKO
IPC: H02K11/00
Filed: 1990-03-07
Abstract: PURPOSE:To increase both starting torque and synchronizing torque by changing the phase difference angle of induced voltage in a rotor conductor at the time of starting and synchronized rotation. CONSTITUTION:A motor is started by closing a power supply in a condition that stator windings 21, 22 are connected so as to obtain a zero phase difference angle of induced voltage in rotor conductors 31, 32 at the time of starting. Here starting torque is increased because no flow of current is generated in a diode 34 by allowing a current in the rotor conductor to flow so as to recirculate in the rotor conductor 32 from the rotor conductor 31. When a rotational speed approaches the synchronous speed, phase difference between two rotational magnetic fields, generated by the rotor conductors 31, 32, is set at 180 deg.. In this way, the current is recirculated through the diode 34 by stopping the recirculation to the rotor conductor 32 from the rotor conductor 31. Thus by forming a magnetic pole in a rotor core, it is rotated while being pulled by a rotational magnetic field generated by the stator windings 21, 22.
