Title: Three-way compressing device
Inventor: KOZUKA GOROU
IPC: B30B1/32
Filed: 1983-07-08
Abstract: PURPOSE:To compress three-dimensionally and equally a material to be compressed and to reduce overall the volume thereof by compressing said material from three-dimensional directions. CONSTITUTION:A material 19 to be compressed is loaded to a loading station R. The completion of the loading is detected by a sensor and a command for energizing is given to the 1st compressing cylinder 12. A piston rod 18 extends and a pressing jig 20 captures the material 19 and feeds the same to a compressing station P and at the same time compresses the material in theY-axis direction by the cooperative action with a supporting plate 46. The two 2nd compressing cylinders 14, 14 facing each other are also energized at a suitable timing, by which the material 19 is compressed in the X-axis direction. The curved surfaces coinciding with the outside surface of the material 19 are recessed to the pressing jigs 20, 26, 26 and the plate 46. The 3rd compressing cylinder extends a piston rod to compress the material in the direction of vertical one axis Z after the compression in the directions of horizontal two axes X, Y of the material 19 is completed, by which the volume of said material is reduced.

Title: Golf club head
Inventor: MUNEKURA MASAAKI
IPC: A63B102/32
Filed: 1995-05-24
Abstract: PURPOSE: To ensure the strength, enlarge and lighten a head and enable effective absorption of shocks in driving the ball while setting freely the weight distribution to each part of the head. CONSTITUTION: A head 1 is composed of a sintered forged component of a united structure. For example, the density of the peripheral part 1b is made higher than that of the central part 1a of the head 1 by changing compression ration in powder molding. The sintered and forged component can be adjusted freely with respect to the density to ensure the strength while the head 1 can be lightened and thus enlarged. Also, since air bubbles exist in the head 1, shocks can be absorbed. Further, through the density distribution in the head can be freely set owing to the enlargement of a sweet area or the like, any problems of the strength as in the case of joining a separate component do not take place.

Filed: 1981-08-11
Abstract: PURPOSE:To perform good development by providing a flexible supplying body of a developing agent in which brush hairs supplying a developing material to a part to be developed is provided on the surface, and a thin-walled part and a thick-walled part are provided in one body on the rear surface in turn. CONSTITUTION:A toner T controlled in a proper quantity on a developing roller 4 is stuck statically on a photoreceptor 1 as brush hairs 12 come into sliding contact with the photoreceptor 1 and a static latent image is developed. The roller 4 is recessed along the surface of the photoreceptor 1 so as to maintain a prescribed contact time, contact width and contact pressure with the photoreceptor 1. As the roller 4 has a thin-walled part 9 and a thick-walled part 10 continued along the width direction and in one body which are provided alternately at the inner side of a roller core body 11, the roller has flexible restoration properties because the deflection of the thin-walled part 9 is generated, and further it has high rigidity to torsion and is deflected parallelly to an axis. Therefore, as the brush hairs 12 are shortened, the dependence on humidity can be lessened. By this way, a development is performed well.

Title: Data chain processing system
Inventor: YAMAZAKI SHIGEO
IPC: G06F13/12
Filed: 1988-05-24
Abstract: PURPOSE:To control the frequent occurrence of data overrun faults when a peripheral control unit PCU executes a data chain DC function by considering not only the data transfer situation of the I/O bus side but that of the device side to detect the data overrun faults of the DC function. CONSTITUTION:In a PCU4 the data are transferred to a buffer 7 from an I/O bus control part 6 and a buffer input side counter 9 subtracts its count value by 1. When the data are transferred to a device transfer control part 8, a buffer output side counter 11 subtracts its count value by 1. When the count value of the counter 9 is equal to 0, a processor 14 gives an instruction to the counter 9 to set the next count value 41 via a buffer input side count register 10. If this setting operation is continued until the count value of the counter 11 is equal to 0, a DC action is continued as it is. Thus it is possible to control the frequent occurrence of the data overrun faults when the PCU4 executes the DC function.

Filed: 1990-05-18
Abstract: PURPOSE:To improve the operating performance of an operator by selecting the substitute value having the repeating frequency different from that selected previously and interactively with the operator or the substitute value of a structure unit. CONSTITUTION:The due processing is carried on with selection of the unfixed frequency of repetition of a certain structure unit out of a common layout structure or the selection of the possible one of structure units of plural types. At the same time, the presence of a substitute means which selects the substitute repeating frequency or a substitute structure unit is stored. When the specific conditions are detected in the subsequent processing operations, it is decided whether the processing is returned to a stored state or not by the conversation carried out with an operator. Then the selection of the substitute repeating frequency different from that selected previously or a substitute structure unit is decided by the designation of the operator. As a result, the layout processing can be tried again with use of another possible partial structure unit. Then the document layout efficiency is improved.
