Title: Cassette for image recording carrier
Inventor: OKODA MAKOTO
IPC: G03B42/04
Filed: 1987-04-16
Abstract: PURPOSE:To permit easy and automatic delivery of an image recording carrier such as accumulation type fluorescent material sheet to a conveyance system by mounting a cap body freely openably and closably to a housing for housing said image recording carrier and disposing an elastic elastic body for imposing the image recording carrier into the housing. CONSTITUTION:The pressing and holding action of the cap body 16 to a leaf spring 30 is released and the leaf spring 30 is curved and displaced upward by its elastic force when the cap body 16 is opened by a suction cup. The accumulation type fluorescent material sheet S imposed on the spring 30 is, therefore, so displaced that the end on a side wall 20a side is inclined upward. Since the end of the sheet S projects upward of a housing, the end can be easily grasped by a roller pair 62 if the roller pair 62 is displaced to the sheet S side. The sheet S is thus delivered toward the 1st conveying means side by the rotating action of the roller pair 62.

Filed: 1986-04-23
Abstract: PURPOSE:To save labor in polishing an end face of a yoke, enhance the rate of heat conduction to the cover side and reduce frictional resistance on a wire, by a construction wherein a bottom surface of a cup form yoke is recessed at a part corresponding to a connecting cable as compared to the other part, and the other part makes contact with a front cover. CONSTITUTION:In a yoke 4, a surface 4B making contact with a flexible cable 19 is recessed from a surface 4A making contact with a front cover 1, and the cable 9 is fitted on the surface 4B. A recessed part of the cover and the recessed part of the yoke 4 define a space for containing the cable 19 and a terminal 18 of a bobbin 17. Therefore, a polishing area in polishing an end face of the yoke 4 is small, and labor can be greatly saved. The surface roughness and the deviation from plane surface of the polished surface can be reduced, and the rate of heat conduction to the front cover 1 side is increased. In addition, since positional accuracy of the front cover 1 and the yoke 4 is enhanced, frictional resistance exerted on a wire 10 by guides can be greatly reduced.

Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To enhance using efficiency of a polishing pad by polishing the polishing object surface by opposing a small lightweight polishing pad holder fixing the polishing pad to the polishing object surface of a wafer. SOLUTION: A wafer 1 is held by one piece in a wafer holding part 2 by turning the polishing object surface upward. A polishing pad 4 is held on a polishing pad holder 9. Next, while dripping an abrasive on the polishing object surface, the polishing pad 4 is placed on the polishing object surface of the wafer 1, the wafer holding part 2 is slowly rotated, the polishing object surface is pressurized by the polishing pad 4, and while applying vibrational motion, the polishing object surface is polished. Since the size of the polishing pad 4 is formed in the size by adding two times amplitude of vibration of the polishing pad 4 to a dimension of the wafer 1, in a polishing process, the wafer 1 is always polished over the whole polishing object surface.  Here, a rotating speed of the wafer 1 by the wafer holding part 2 is decided so that peripheral velocity on the outermost side of the wafer does not exceed an average speed by vibration of the polishing pad 4 at its maximum.

As a result, the action of the rocker arm 10 is transmitted to one intake valve to open and close it. When the engine is in a middle speed range, the valve 24 is closed but another valve 44 is opened to put the rocker arm 10 out of operation and the other rocker arm 30 in operation to open and close one intake valve by only the high speed cam. When the engine is in a high speed range, the valves 24, 44 are opened to open and close both the intake valves. The charging efficiency of the engine is thus enhanced.

Abstract: PURPOSE:To stack josephson devices in multilayers through a flat-face layer insulation without use of resist by employing an oxide material which can be converted from an insulator to a superconductor by a laser annealing. CONSTITUTION:When a BaPb1-xBixO3 (0.05<=x<=0.30) or Lii+xTi2-4O4 (0.2<=x <=0.3) is evaporated on a normal temperature Si substrate 1, it takes amorphous form but can be converted to a superconductor or a semiconductor (resistor) by laser annealing. According to this method, first, a wiring layer 2 is formed. Then, layers 3 of this composition are piled and undergoes annealing to make an electrode 4 and a wiring 4'. Subsequently, layers 7 of the same composition are piled again through a tunnel barrier layer 6 made of a specified material to provide an upper electrode 8, a wiring 8' and a layer connectin 9 likewise. Thereafter, likewise, a control line 11, a layer connection 12 and a wiring layer 2 are formed in sequence on the layers 10 and 13 of the same composition. With such an arrangement, a multilayer stacking is possible because of the flat surface of the circuit thereby enabling integration.

Filed: 1991-04-02
Abstract: PURPOSE:To make a memory instruction code part unnecessary in a specific address and to easily store instructions in a memory on the same chip by providing the microprocessor with a circuit for selecting a specific instruction corresponding to a specific address. CONSTITUTION:A program counter 1 is driven and a specified address in a memory is read out by the memory address of an instruction to be executed. A memory output read out of the memory 2 is latched by an instruction register 3 and decoded by an instruction decoder 4 and a control signal 5 is outputted. When the contents of the counter 1 indicate previously determined contents, i.e., a specific memory address, a specific address decoder 6 decodes the specific memory address and outputs a control signal 7. Thereby the specific instruction corresponding to the previously determined specific address is controlled. Consequently the memory instruction code part of the specific address can be deleted without depending upon instruction codes stored in the memory 2.
