Patent JP-H03294040-A (JP)
Title: Casting device
Inventor: MURAMATSU TATSURO
IPC: B22C9/08
Filed: 1990-04-10
Abstract: PURPOSE:To prevent the development of defect in a product part by setting a fixed strainer providing a communicating hole in sprue system, opening the communicating hole while a dynamic pressure of molten metal is in operation and closing the communicating hole when the dynamic pressure becomes zero. CONSTITUTION:The fixed strainer 13 providing the communicating hole 15 is set at the optional position in the sprue system. A runner shut-off member 17 is set at the position near the fixed strainer 13. This runner shut-off member 17 is formed with a material having sp. gr. smaller than that of the molten metal. This is pushed to one direction while the molten metal is filled up in the sprue system and the dynamic pressure acts to open the communicating hole 15 in the fixed strainer 13. When the filling-up of molten metal completes and the action of dynamic pressure becomes zero, this is shifted to the other direction with buoyance of the molten metal to close the communicating hole 15 in the fixed strainer 13. By this method, deterioration of the quality in the product part can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent excess chemicals discharge to a releasing body according to temperature changes, by constituting a supply body by a matter capable of supplying chemicals in a soft package to the releasing body without replacing air. SOLUTION: A high density impregnation body 4 is formed by a liquid absorptive matter capable of supplying a liquid flavor chemical in a soft package 10 to a releasing paper 3 without replacing air. The lower end part of the high density impregnation body 4 is brought in contact with a dent part 3a of the releasing paper 3 through each circular holes 7a and 6b1 of a lower cap 7 and a dent part 6b, The upper end part is protruded in a liquid flavoring agent A. The density of the high density impregnation body 4 is preferable to be not lower than 0.6g/cm<3> , and highly, compressed pulp, etc., is used as the material. By this constitution, since outer sir does not penetrate through the high density impregnation body 4 into the soft package 10 even if the atmospheric temperature elevates, the temperature change does not affect on the action and excess discharging is prevented.

Title: Dc motor control system
Inventor: HAYASHIDA NOBUYUKI
IPC: H02P3/12
Filed: 1979-07-25
Abstract: PURPOSE:To rapidly switch from high to low speed for a DC motor by starting a constant speed control at low speed control at low speed of the motor when the real  speed for regenerative braking the motor is lowered than the low speed specified  speed in case the motor is switched from high to low speed. CONSTITUTION:When a real speed of a DC motor is faster than a specified speed, a speed control signal VFS becomes a high level, while when the real speed is lower than the specified speed, the speed control signal VFS becomes a low level. A motor control circuit 13 controls the motor 1 in response to the speed control signal VFS. When the motor 1 is switched from high to low speed, the specified speed is altered and a run signal STA is turned off. Thus, the motor 1 is regneratively braked to abruptly decelerate the speed of the motor 1. Thereafter, when the fall of the speed control signal VFS is detected, the run signal STC is turned on to control constant speed of the motor 1.

Title: Print system
Inventor: KOGA MIKIO
IPC: G06K15/10
Filed: 1979-07-24
Abstract: PURPOSE: To remarkably reduce the amount of transfer of dot pattern, by transferring only the character part, through the use of the print system in which the dot signal at the space between characters is not transferred.  
     CONSTITUTION: To the 2nd comparison circuit 8, the space insertion amount signal representing the space between characters produced from the addition and subtraction circuit 5 is transferred. Further, when the output of the space insertion counter 7 and that of the circuit 5 are in agreement, the circuit 8 outputs the H level output signal and transfers it to the inverter 10 and the information transfer control circuit 1. Accordingly, the output of the inverter 10 is at low potential, and the output of clock pulse is stopped from the multi-input AND circuit 9. In this case, the buffer address counter 12 shows the final end of the space between characters. Thus, without transferring the dot signal at the space between characters, and by transferring only the character parts, the amount of transfer of dot pattern can remarkably be reduced.

Title: Double hammer pile driver and operating method thereof
Inventor: NARATA TOMOYUKI
IPC: E02D7/08
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of noise by setting the feed quantity of pressure oil per unit time fed to a hydraulic cylinder in the direction of making a first hammer descend, to be smaller than the quantity expressed by a specific expression and to be close to this quantity. SOLUTION: A selector valve is switched in the lifted state of a first hammer 23 to supply pressure oil to a first hydraulic cylinder 8 through a fall time feed oil passage. Then the first hammer 23 and a second hammer 24 fall. When negative pressure is generated to the cylinder 8 due to resistance in a hydraulic circuit, and downward resistance acts upon a running block 6, the hammers 23, 24 fall constrainedly while constraining each other. In addition, pressure oil in the feed quantity smaller than Q=gtS/2 (g: gravitational acceleration, t: elapsed time from a fall starting point of time and S: effective sectional area of a piston of a cylinder), and close to the flow Q is fed to an ascending time return oil passage, and resistance of the hydraulic circuit is offset to impart thrust to the piston. The hammer 23 is thereby landed early.  As a result, the hammers 23, 24 do not fall in the same phase, so that noise can be prevented.
