Title: One-way clutch
Inventor: ISHIKAWA KAZUO
IPC: F16D41/06
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To unnecessitate a cage and a spring and to reduce the number of parts and assembling man-hour by using connecting pieces as a plate spring made of metallic thin plates. SOLUTION: Between an outer race 1 and an inner race 2, a plurality of sprags 3 connected with each other by U-shaped connecting pieces 13 are arranged. Each of the sprags 3 is held in a state of the sprags 3 energized to rotate counterclockwise by elastic force of the connecting pieces 13. When the sprags 3 are held on the side of the outer race 1 when the inner race 2 is rotated counterclockwise in a fixed state of the outer race 1, the inner race 2 slides on cam surfaces 3b of the sprags 3 and freely rotates as shown by an arrow on the side of the inner race 2. Conversely, when the inner race 2 is rotated clockwise in a fixed state of the outer race 1, the inner race 2 is locked after the sprags 3 are slightly rolled counterclockwise, pressing the cam surfaces 3b by friction, and rotation of the inner race 2 is transmitted to the outer race 1 via the sprags 3.

Title: Transferring process of resin
Inventor: YASUZAWA KAZUHITO
IPC: B32B37/00
Filed: 1984-07-07
Abstract: PURPOSE:To transfer the resin containing less bubbles to a working place by a method in which the pressure of the inside of the tank which is placed at a high position and provided with an evacuating means is reduced, and the resin is once stored in this tank due to said pressure difference, and then the resin in the tank is caused to drop onto an objective place by the action of gravity. CONSTITUTION:The pressure of the inside of an agitating tank 2 is reduced by an evacuating means 2b, and the resin raw materials 1a, 1'a in raw material tanks 1, 1' are transferred into the agitating tank 2 due to their pressure difference. Then, a resin (resin wax) 8 is prepared while mixing the raw materials 1a, 1'a by an agitating means 2a. The agitating process is carried out, while operating the evacuating means 2b, whereby the bubbles in the resin 8 are removed. Next, the pressures of the insides of defoaming tanks 3, 3' are reduced by an evacuating means 3a and the resin 8 in the agitating tank 2 is caused to drop in the defoaming tank 3 or 3' owing to their height difference (gravity) or the combination of the height difference and their pressure difference. Then, the resins having entered the defoaming tanks 3, 3' are caused to pass through paths 3b in the state of thin film. When the resin 8 is in thin film state, the bubbles in the resin 8 are easily separated.

Title: Bone prosthesis

IPC: A61F2/34
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To make local normal stress and shear stress minimum actinon between a bone and a prosthesis, by making a mathematical simulation model and determining shape dimensions by a mathematical retrieval procedure. SOLUTION: The stress at a nodal point i on the interface, which is loaded by an external load M, of a prosthesis 1 and a bone 2 is calculated. An object function FG corresponds to the design standard and the object function FG is minimized. Next, a nodal point j on an interface of a metallic stem and a cement cortex is moved across a small interval and new shape dimensions are obtained. A function FGi is calculated with respect to nea shape dimensions. This procedure is applied on all of nodal points j, and obtain function values FGi are compared with the initial value FG. Corresponding to the reduced amount of the function values FGi compared with the initial value FG, the shape dimensions are converted to new values via a prescribed algorithm, i.e., minimum algorithm, and, as a result, the function value F'G becomes smaller than the initial value FG.  Next, after the shape dimensions are replaced and inserted in t a bone, the stress on the abutting face becomes lower as far as possible and has a uniform distribution value.

Title: Dma control circuit
Inventor: MANIWA YOSHIO
IPC: H04N1/41
Filed: 1980-10-13
Abstract: PURPOSE:To hold the continuity of serial data, by detecting by a counter that a shift register for serial/parallel conversion is full of data and by detecting the completion of input transfer to a memory by the output of an FF which is reset at this detection time. CONSTITUTION:The number of bits of input serial data to a shift register 71 is counted by a counter 74, and parallel converted data due to the register 71 is transferred to a latch 72 by a register full signal 107. By the control of a timing control part 79, an address and data are written to a memory device through a buffer 73. This operation is repeated succesively; and when a busy signal falls at the last of input data, the last parallel data is written to the memory after the register full signal 107 comes, and simultaneously, an FF75 set at the first of input data is reset to indicate the end of data write. Thus, the continuity of serial data is held without inserting excess data.

IPC: H03F3/34
Filed: 1988-06-09
Abstract: PURPOSE:To easily set a desired variable range and to reduce a range of dispersion by controlling feedback quantities in first and second feedback quantity variable circuits. CONSTITUTION:The collectors of transistors 1 and 3 and that of transistors 2 and 4 that are output of a bi-differential amplifier are connected in common, and are fed back to the base of a transistor 5 by transistors (12-17) consisting of current mirrors, respectively.

In such a way, it is possible to set the desired variable range easily since the range of variance can be set on only the capacitance, and furthermore, only the capacitance becomes the factor of the dispersion, which suppresses influence due to the dispersion in another element.
