Patent JP-S59121202-A (JP)
Title: Fluid pressure device
Inventor: IKEDA TOSHIO
IPC: E02F9/22
Filed: 1982-12-28
Abstract: PURPOSE:To prevent the generation of thermal shocks by such an arragement that each of flowrate and direction control valves is provided with a pilot passage which is interconnected to a tank passage at the control valve's neutral position and closed at its change-over position. CONSTITUTION:The secondary side of a decompression type pressure compensation valve 102 is connected to the spring chamber of a load sensing valve 163, and the load sensing valve is controlled so that it causes a variable fluid pressure pump 162 to discharge a fluid at such a pressure and flowrate that correspond to the load pressure of an actuator at all times. Each of flow-rate and direction control valves 103-106 is provided with a pilot passage 108 which is interconnected to a tank passage 113 at the control valve's neutral position and is closed at its change-over position. The passage 108 is connected to the secondary side of the pressure compensation valve 102. Consequently, even in a feathering situation, a small amount of fluid is caused to flow through the pilot passage 108 and it prevents the fall of temperature of the flow-rate and direction control valves 103-106.

Title: Device for processing graphic of logical circuit
Inventor: NISHIO SEIICHI
IPC: G06F17/50
Filed: 1987-09-16
Abstract: PURPOSE:To generate the graphic of a logical circuit in the size of an optional graphic with respect to a circuit including a large logical symbol by dividing the logical symbol in which the number of pins on an input side or an output side exceeds a value into the logical symbols in which the number of pins do not exceed the value. CONSTITUTION:A pin number value storage means 1 stores the value of the number of the pins in the logical symbol which can be handled in the size of respective graphics. If a logical symbol division means 2 generates the graphic of the logical circuit in the size of the specified graphic, the value of the pins corresponding to the size of the graphic is referred and the number of the pins of respective logical symbols in the logical circuit is checked. If the logical symbol where the number of the pins on the input side or the output side exceeds the value exists, the logical symbol is divided into plural logical symbols where the number of the pins do not exceed the value. Thus, the graphic of the logical circuit in the size of the optional graphic can be generated with respect to the logical circuit including the blocks having a large number of the pins.

Title: Robot controller
Inventor: KOYANAGI HARUO
IPC: G05D1/02
Filed: 1985-10-17
Abstract: PURPOSE:To expand the working range of a robot, by simultaneously performing servo control of each articular axis of the robot main body and running axis which runs the robot main body by means of a single robot controller by treating the running axis as one of the motion axes of the robot. CONSTITUTION:In the case of the simultaneous PTP operation of a robot running axis, the moving quantities of each axis and running axis of a robot main body are simultaneously calculated at an arithmetic section 2 and each articular axis driving motor 15-16 of a robot main body driving section C and running axis driving motor 17 of a running axis driving section D are respectively driven by motor drivers 6, 7, and 14 in accordance with the calculated results. In the case of the simultaneous CP operation of the robot running axis, the arithmetic section 2 calculates the moving quantity to each articular axis of the robot main boy only, since the movement in the Y-axis and Z-axis directions is performed by the robot main body only. On the contrary, only the moving quantity of the running axis is previously subtracted from the moving quantity in X-axis direction and the arithmetic section 2 calculates the moving quantity so as to cause the axis of the robot main body to make operation by the difference in the case of the movement in X-axis direction, because operations in X-axis can be performed by both of each axis and running axis of the robot main body.

Title: Magnetic recording and reproducing device and its operation guaranteeing method
Inventor: ARAKAWA YUTAKA
IPC: G11B21/08
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To raise the temperature in an HDD device to an operation guaranteeing range by selectively supplying electric power to a prescribed circuit of the device when the temperature in the device is lower than the range. SOLUTION: When the temperature in the device is lower than an operation guaranteeing range, electric power is supplied to a VCM/SPM driver 5 in the device for a prescribed time so that an SPM 2 is rotated and the temperature in the device is raised by the heat generated by windage of a disk and friction loss of a spindle. Then, the temperature of a temperature sensor 13 is confirmed by a temperature sensor monitor 12 so as to judge whether the temperature in the device is within the range or not. If the temperature is within the range, the operation is stopped. When the temperature is less than the range, power is applied to a VCM 4, which is a head driving means in the device, for a prscribed time and also a dummy seek of a magnetic head 3 is executed to raise the temperature in the device.

Title: Electrostatic charge image developing toner
Inventor: HIYOUZU YOSHIHIKO
IPC: G03G9/087
Filed: 1983-12-06
Abstract: PURPOSE:To improve fixability, offset resistance, and blocking resistance by using a substantially spherical toner having a specified practical sphericity and a specified number average particle diameter, and contg. a hydrocarbon compd. grafted with a cationic monomer. CONSTITUTION:A toner has a substantially spherical form and a Wadell's practical sphericity of 0.95-1.00 and a number average particle diameter of 5-25mum, and contains a hydrocarbon compd. grafted with a cationic monomer. Such a toner can be prepared by the suspension polymn. method using, e.g., an anionic dispersant. At the time of such suspension polymn., since said hydrocarbon compd. gathers on the surface of each suspended particle, and distribution of the monomer system into the dispersion medium does not occur at all, the interface of each suspended particle is kept stable. The coalescence of the particles does not occur at all and a toner uniform in particle diameter is obtained because the anionic dispersant combines with interface of the suspended particles by the ionic bond, and covers the surfaces. Such a toner is uniformly triboelectrified, good in fluidity, small in amts. of fine or coarse particles, thus permitting a sharp image free from fog and scattered spots to be obtained.

Title: Driving system of dot printing head
Inventor: TANUMA JIRO
IPC: B41J2/30
Filed: 1987-09-17
Abstract: PURPOSE:To enable high speed and efficiency to be achieved by correcting a driving time at each dot pin, by a method wherein a specific value concerning a dot pin has been previously stored in a storage means established to a dot printing head body, and this specific value is preliminarily read at a power on reset or system reset signal offering time. CONSTITUTION:A correction circuit 11 receives a printing pattern signal b from a control circuit 10, and stores a correction value Z(i) from the same circuit 10. At the same time, the correction circuit 11 sends a delay printing pattern signal b' in which time for sending the printing pattern signal b to a driving circuit 3 is delayed based on the correction value Z(i) to the driving circuit 3. A characteristic storing part 13 in which a characteristic value Y(i) peculiar to each dot pin is stored is established to a printing head. When power on reset or system reset on closing a power source is set, the control circuit 10 reads the characteristic value Y(i), and calculates the correction value Z(i) to be stored in the correction circuit 11. When printing is commanded from an external device such as a personal computer or the like, each dot pin is driven for a driving time corresponding to the correction value Z(i) to perform printing.
