Title: Follow-up type robot device
Inventor: SHIBATA KUNIROU
IPC: G05B19/18
Filed: 1984-05-22
Abstract: PURPOSE:To attach, detach and assemble, etc. parts with respect to a rotary table without making the rotary table stand still, by making a work head of a robot follow up by a circular interpolation so as to synchronize with a rotation of the rotary table. CONSTITUTION:When a counter PDC of a memory 36 is reset by following an operation of an original point detector 14, thereafter, the servo-computer 32 compares a value set to a set area DSA of the memory 36, and the contents of PDC for detecting a table rotational angle based on an original point position as a reference. When both of them coincide, an interrupting signal is sent out to a central processor 30, and by this interrupting signal, the central processor 30 commands a follow-up movement of a robot 20 to a servocomputer 33. Based on it, a work head 25 of the robot 20 is moved by synchronizing with part W1 on a rotary table 10 by a circular interpolation between points taught by each joint in advance.

IPC: G11B5/49
Filed: 1983-06-13
Abstract: PURPOSE:To decrease the man-hour of assembly and at the same time to increase the life of a magnetic disk by using plural units of a fixed head block of the same constitution mounting plural magnetic heads respectively. CONSTITUTION:Plural fixed head blocks 11-13 mounting plural magnetic heads 10 respectively are distributed toward the same direction spacing by a different distance the center O of a disk 14. Thus every head 10 is set opposite to a different track respectively. The inclination alpha between the track of the disk 14 and the heat 10 is maximum at the inner-most part, and the same constitution is available with blocks 11-13 as long as the consideration is given to the number of lunits and the distribution of heads 10 on these head blocks. This facilitates extremely the assembly and a control process. At the same time, the head blocks can be moved to made the heads 10 movable between the data zone and the start/stop zone of the disk 14. Thus the reduction of the disk life owing to the wear can be prevented.

Title: Magnetic head
Inventor: OKADA SUSUMU
IPC: G11B5/245
Filed: 1983-06-10
Abstract: PURPOSE:To increase the high frequency permeability and to improve the reproduction efficiency by forming a magnetic head core so that the magnetic domains are arrayed at a specific angle in the direction vertical to the direction of the magnetic flux produced from a medium. CONSTITUTION:It is desirable to attain the structure of a magnetic domain where the process of magnetization is set in a rotary magnetization mode in order to improve the high frequency permeability of the magnetic core of a magnetic head. In other words, a magnetic flux 5 produced from a medium circulates within a magnetic core 1. Therefore it is desirable to obtain the magnetic domain structure where the spin direction is orthogonal as much as possible to the direction of the magnetic flux 5 within the rate 1. In this case, the magnetic domains are arrayed vertically by 180 deg. to the direction of the flux 5. Such magnetic domain structure is attained by applying magnetic field toward an arrow H for an annealing process. The spin direction and a magnetic wall are shown by symbols 6 and 7 respectively.

Abstract: PURPOSE:To reduce the capacity of a driving spurce as well as to make a device inexpensive in cost by installing a cam follower to be followed to the circumferential surface of a cam disk and a controller which moves a shift ring and starts and stops a driving system. CONSTITUTION:An R type transmission 1 driven by an electric motor drives an output shaft 3 via a worm gearing. On this output shaft 3, there is provided with a cam disk 5 where four recesses 4 are installed on the circumference. A spring 11 exerts such force as trying to move a shift ring 10 in the speed increasing direction. In order to hold a ring holder 13 in a position making rotational speed of the output shaft 3 into zero, a rack-and-pinion mechanism 14 is interposed between an arm 9 of a bell crank 7 and this ring holder 13. Thus, the capacity of a driving source is lessened, and a device can be made very inexpensive in cost.

Abstract: PURPOSE: To prevent buckling, wrinkle or the like caused at the time of bending a hollow double pipe. CONSTITUTION: Bending of the hollow double pipe is executed by a process in which a backup material whose Young's modulus is 3-10GPa is charged into the space 3 of the hollow double pipe 1 through which an internal pipe 4 is inserted leaving a prescribed space 3 inside an external pipe 2, process in which the hollow double pipe 1 is bent by applying bending force to the hollow double pipe 1 in which the backup material is charged and process in which the backup material is removed from the bended hollow double pipe 1. Bending is executed after charging the backup material whose Young's modulus is 3-10GPa into the space 3, a prescribed strength is maintained and the internal pipe 4 and external pipe 2 are backed up, so the occurrence of eccentricity, buckling and wrinkle of the internal pipe is eliminated and the deformation of the external pipe 2 is suppressed.

Abstract: PURPOSE:To prevent the erroneous issuing of upper and lower-limit abnormal alarms by stopping a normally operating upper and lower-limit monitor function only when start and stoppage control is conducted to high load facilities. CONSTITUTION:The information of designated facilities indicated by a monitor operation table 2 is transmitted over a high-load facility decision means 8 first. When facilities existing in a previously assigned high-load facility group are designated, a signal is sent to a monitor stoppage means 9 at that time, the signal is held for a fixed time, and an inhibition signal is transmitted continuously over an upper and lower-limit monitor means 10. Control indication information is sent to a control output means 11 as it is, the position of a terminal, where a control signal is output actually, and signal contents are determined, and the control signal is output to the designated facilities. An analog value from receiving and transformation facilities, etc., is taken in, and compared with upper and lower-limit values set by the operation table 2 and abnormality is decided when the analog value is deviated from the set range of the upper and lower-limit values as a monitor function, but the function is stopped during the time when the inhibition signal is transmitted from the monitor stoppage means 9.

Title: Reactor shutdown device
Inventor: HORIKAWA YUJI
IPC: G21C7/14
Filed: 1989-04-25
Abstract: PURPOSE:To improve the responsiveness of the device to an abnormal temp. rise of coolants and to allow a sure scram by specifying the total aperture area of the coolant outflow holes provided in the upper part of an introducing pipe to the area larger than the sectional area of the flow passage in the introducing pipe. CONSTITUTION:The introducing pipe 7' which introduces the coolants 21a, 21b flowing out of a lower guide pipe 12 of a control rod provided in the reactor core 11 and a lower guide pipe 13 of a fuel assembly into an upper guide pipe 2 is integrally provided at the bottom end of the pipe 2. The coolant outflow holes 15a, 15b which discharge the coolants 21a, 21b flowing into the pipe 2 are provided in the upper part of a pipe 7'. Since the total aperture area of the holes 15a, 15b is set larger than the sectional area (pid<2>/4, d is the bore of the pipe 7') of the flow passage of the pipe 7', the flow resistance near the inlets of the holes 15a, 15b decreases to assure the smooth outflow of the coolants 21a, 21b flowing into the pipe 7' from the holes 15a, 15b. The generation of back flow in the pipe 7' and the generation of the stagnating part of the coolants 21a, 21b near the bottom end of the extension pipe 7 are, therefore, obviated.
