Title: Ball for ball point pen
Inventor: ITO ATSUSHI
IPC: B43K1/08
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a ball for a ball point pen which writes well for a long time by alleviating the wear of a pen point main body. SOLUTION: This ball for a ball point pen is made of a sintered body obtained through sintering rigid particles. In this case, by setting the average interval between particle boundaries less than 0.2 μm, the thinner the gap between the rigid particles becomes, the finer the small piece of the rigid particle exposed beyond the sintered metal portion on the surface of the ball becomes. In addition, the number of the rigid particles becomes very small. Accordingly, the number of the small pieces acting as abrasive through their falling off during use becomes very few, resulting in preventing a pen point main body from being worn and the ball from sinking in the pen point main body.

Title: Method and device for preventing collision of moving body
Inventor: YOSHIDA YUTAKA
IPC: B65G1/00
Filed: 1987-10-19
Abstract: PURPOSE:To improve cargo working efficiency in the captioned device for an overhead crane, etc., by obtaining the distances to the stoppage of two moving bodies from their respective traveling speeds and, when the sum of the stopping distances of both is smaller than the distance between the moving bodies outputting a stop signal to the moving bodies. CONSTITUTION:Each of collision preventing devices 10A, 10B loaded on moving bodies 1A, 1B calculates relative distances Ls while judging the traveling direction of itself, operates relative speed Vs and, further, determines the opponent's speed Ve from the relative speed Vs and its own speed. Then, by operating the stopping distance Ld of itself and the opponent's stopping distance Le, a margin distance Lk is obtained by a defined calculating formula depending on whether the opponent's speed Ve is 0 or not. By comparing this margin distance Lk with specific values K1, K2 and, if it is below the specific values K1, K2, since there is a possibility of collision, alarm signals ALM are outputted, commanding a stopping operation. By this structure, the operating rate of the collision preventing devices can be lowered, improving cargo working efficiency.

Title: Picture processor
Inventor: TAKAMORI TETSUYA
IPC: G06T1/00
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To process plural processings in parallel at high speed and to process them even if input/output are asynchronous by executing the plural processings for respective lines and instructing the processing of the next line by the termination of the operation of all processing units. SOLUTION: The plural processing units 12-16 process the respective processings at every line of the picture, and generate signals showing the termination of the operation. When a controller 17 receives the signal showing the termination of the operation of all the processing units 12-16, it simultaneously instructs the start of the operation of one line in the next picture to all the processing units 12-16, In the processing units 12-16, they simultaneously start the operation in synchronizing with the start of the line processing instructed from the controller 17. The previous processing is terminated in all the processing units 12-16 at that time. Thus, the processing unit 14 executes the processing while it reads data whose previous processing terminates from the buffer memory of the previous processing unit 13, for example.

Title: Magnetic disk device
Inventor: HOSHINA MASAKI
IPC: G11B17/038
Filed: 1985-11-21
Abstract: PURPOSE:To reduce the deflection of the vibration of a disk due to rotation by agreeing the width of a jointed surface of a clamp plate and a disk with that of a jointed surface of a spacer and the disk. CONSTITUTION:The jointed surface of the clamp plate is scraped so that the width 7 of the jointed surface between the disk clamp plate 5 and the magnetic disk 3 and the width 7 of the jointed surface between the disk spacer 4 and the disk 3 can be of the same dimensions. Accordingly force tightening the disk 3 can be constant, and such a trouble that the disk 3 is obliquely fitted is eliminated. As a result, the disturbance of the rotation when the disk 3 is rotated disappears to reduce the deflection due to the vibration, thereby improving the reliability of the device.

Title: Nonlinear compression device for digital signal
Inventor: MORIWAKI HISAYOSHI
IPC: H03M7/38
Filed: 1985-11-21
Abstract: PURPOSE:To eliminate the effect of an offset of an A/D converter by applying nonlinear compression processing to a signal, which is the output signal of the A/D converter passing through a high pass filter. CONSTITUTION:A digital high pass filter is provided between the A/D converter and the nonlinear compression circuit, and since a DC component of an output of the A/D converter is eliminated by the high pass filter, the effect of the offset of the A/D converter is eliminated. Since the offset appears as the DC component even when the A/D converter 1 has the offset, the DC component is eliminated by the high pass filter 2. Thus, all zero is the center level without fail at the input side of the compression circuit 3, the offset is eliminated substantially to aply the ideal nonlinear conversion.

Title: Tape loading mechanism for magnetic recording and reproducing device
Inventor: KAKU NOBUYUKI
IPC: G11B15/665
Filed: 1985-11-25
Abstract: PURPOSE:To prevent a magnetic tape from being damaged by providing a subguide which can abut only on the magnetic tape during loading without touching a tape travel path finishing loading. CONSTITUTION:When a guide base 35 moves, an arm 44 located on the route for said base abuts on the side of the guide base 35. Therefore the arm 44 turns clockwise with a pin 45 as a center and a full width erasure head 15 and impedance roller 16 on the arm 44 retreat from a rotating cylinder 2. Thus winding of the magnetic tape 6 is unwound. On the other hand, since the locking pin 47 of the arm 44 turns a subarm 49 counterclockwise with a pin 50 as a center, a tilting subguide 48 advances toward the side of the rotating cylinder 2, and winds the magnetic tape 6, instead of the full width eradure head 15 and the impedance roller 16. The tilting angle of the tilting subguide 48 is appropriately set, whereby undue force hardly applies to the magnetic tape 6.
