Patent JP-S5810447-A (JP)
Title: Cam grinding machine
Inventor: KISHIDA KOUKI
IPC: B24B19/12
Filed: 1981-07-10
Abstract: PURPOSE:To provide any profile to a workpiece without producing an idling to the workpiece by tilting a cradle supporting the workpiece through a numerically-controlled stylus in a cam grinding machine provided with a rotary grind- ing stone. CONSTITUTION:A cradle 1 is freely tilted back and forth around a fulcrum of a shaft 2. A workpiece 3 is supported by a shaft 4 on the surface of the crade 1 in such a way that the workpiece may freely rotate. When a stylus 8 is driven back and forth under numerical control after the workpiece 3 is rotated by a prime mover, the workpiece 3 is subjected to the action of the stylus 8 on a cylindrical member 7 on the same shaft 4, which produces a responding back and forth movement. With this action, the workpiece 3 can be cut into a specified profile with a rotary grinding stone 6. As the stylus 8 supports the back of the workpiece 3 through the cylindrical member 7, no idling is produced by even heavy grinding.

Title: Temperature controller for heat pump type hot water supplier
Inventor: MATSUMORI MASATO
IPC: F24H1/18
Filed: 1981-07-08
Abstract: PURPOSE:To obtain such a temperature control as supplement shortage in boiling and reduces heat leakage by a method wherein power supply to a heater is controlled in accordance with a water temperature when a time limit mechanism is operating after an elapse of a time remaining before a time limit for supplying power to the heater. CONSTITUTION:A temperature setting part 24 presets a preset temperature Tf and the water in a hot water tank is heated to a temperature T1 by a freezing cycle 1. Then, a time ta required for heating the water by the heater 4 from T1 to Tf is calculated in an operation circuit 25, and the time (8-ta) remaining before the power supply time limit is set automatically in a time limit mechanism 16. When the temperature of the water in the tank does not reach T1 after the time (8-ta) has elapsed, the time limit mechanism 16 operates a relay 17 to stop the operation of a circulation pump 3 and the freezing cycle 1 when the time (8-ta) is up, whereas power is supplied through a relay 20 to another heater 15 having a larger performance. If the temperature of the water reaches T1 before the time (8-ta) elapses, a thermostat 5 detecting the temperature of the water at an inlet of the pump 3 opens so as to operate a relay 11 to stop the operation of the pump 3 and freezing cycle 1. When the time (8-ta) has elapsed, the time limit mechanism 16 makes the relay 17 operate, whereas the relay 20 does not operate because of the opening of the thermostat 5, thereby permitting the power supply to the heater 4 only.

Title: Detecting method of inner defect at resin seal of molded product
Inventor: SAEKI JIYUNICHI
IPC: B29C33/12
Filed: 1983-06-17
Abstract: PURPOSE:To detect accurately the defect occuring in a product by detecting the elastic wave with high frequency which is generated when cracks or the separation of resin surface from an insert are generated at the time mold release by an acoustic emission sensor (AE sensor). CONSTITUTION:When the hardening of the resin in a cavity is finished and molds are released a bottom force 7 and the tip portion 20 of the ejection pin in a top force are synchronously lowered and a molded product 28 is separated from the cavity 3 of the top force. Then, when cracks or the separations of resin surface from an insert are created, the elastic wave with high frequency is gen- erated therefrom, thereby vibrating the surface of the molded product with small amplitude. This vibration is transmitted to an AE sensor 19, and converted into voltage there. The voltage signal is introduced into a monitor alarm device 23. Because the noise caused from outside is cut off by a filter, the monitor alarm device 23 can detect accurately only the defect occurring inside of the molded product at the time of mold release.

Abstract: PROBLEM TO BE SOLVED: To conduct conversion of excellent scanning line number with a simple configuration. SOLUTION: A video signal fed to an input terminal 1 is written in field memories 23-26 through line memories 21, 22. The write/read of the memories 21, 22, 23-26 is controlled optionally by a control circuit 27. Then the signals read from the memories 23-26 are fed to multiplier circuits 28-31, in which coefficients are multiplied with the signals and the products are added by an adder circuit 32. Furthermore, a microcomputer 5 calculates the conversion ratio in a scanning line conversion section 2 based on an input signal system and an output signal system and the calculated ratio is stored in a read only memory 8 in which a conversion table is stored.  Then the coefficients multiplied in the multiplier circuits 28-31 and a shift amount of the scanning lines read from the memories 23-26 are read for each scanning line conversion according to the ratio as above from the read only memory 8.

Title: Estimation of overvoltage at interruption of 3-phase circuit
Inventor: IKEMOTO KUNIO
IPC: G01R27/02
Filed: 1987-04-30
Abstract: PURPOSE:To achieve the optimum designing for the protection of overvoltage, by a method wherein the cause of a phenomenon that a load side potential shifts DC-wise with respect to the ground after a full-phase interruption is clarified to determine a shift portion of the potential paying attention to the phenomenon and overvoltage is estimated allowing the shift portion. CONSTITUTION:In a DC-wise shift phenomenon of a load side potential as noted when a non-grounded 3-phase circuit is interrupted, attentions are paid to a charge of a load side capacitance based on a deviation of interruption time between first and third phases. Then, an interruption current as the charge current is measured by testing it many times at each circuit constant to determine a relationship between the mean of the current and the circuit constant. With this, a relationship is determined between a difference in interruption time of the second and third phases as charge time and circuit constant. This facilitates the estimation of a DC shift voltage in an actual circuit thereby enabling estimation of overvoltage after the full-phase interruption appropriately and easily.

Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a transmission method of a digital program with security to in-home digital devices even when parts of the devices are not allowed by a digital broadcast system. SOLUTION: The system is provided with a matrix whose elements are device keys Si,j, where 'i' denotes a key index variable indicating a position in the matrix in terms of a key-dimension and 'j' shows a set index variable depicting a position in the matrix in terms of a set-dimension. This matrix is used to assign plural device keys each assigned to only one in-home device depending on each key index variable 'i'. In order to generate a session key for a broadcast program, all the device keys Si,j, are used to encrypt session numbers xi and to generate a session key block that is used to generate the session key that decodes the program by each in-home device.  In the case that any of the devices is a device not permitted by the digital broadcast system a dummy number is assigned to at least a session number 50 that the dummy number is encrypted by a corresponding key for the device not permitted by the system and the resulting decoded session key is not useful to decode the program key.

Title: Reel driver for tape recorder
Inventor: AKIWA KAZUO
IPC: G11B15/46
Filed: 1988-04-30
Abstract: PURPOSE:To obtain a stable low speed feeding of a tape by a sole reel motor by supplying a pulse voltage having variable amplitude to a DC motor for rotating the reel. CONSTITUTION:When the slide terminal 7 of a variable resistor VR is moved from a center toward a right side terminal 5, a voltage is generated at the control voltage input terminal 1a of a motor driver 1 and the input terminal of a comparator C01. Thus, the output of the comparator C01 becomes a high level. In this case, a pulse voltage having an amplitude proportional to the voltage of the terminal 1a is generated in a direction from 1e toward 1d at the control outputs 1d, 1e, and a motor 2 is normally driven. When the slide terminal 7 of the resistor VR is moved from its center toward its left side terminal 6, the output of a comparator C02 becomes a high level, and the motor 2 is reverse driven. Thus, the tape feeding speed can be stably and effectively set.
