IPC: G21C7/10
Filed: 1987-09-17
Abstract: PURPOSE:To increase the speed of inserting a cylindrical body, which is freely movable in a perpendicular direction at a prescribed amplitude, onto a control rod assembly and to shorten the time for control by providing the above- mentioned cylindrical body to the outside circumferential part of a base plate and providing a buffer device which controls the rapid vertical movement of the cylindrical body between the base plate and the cylindrical body. CONSTITUTION:The cylindrical body 10 which is freely movable at the prescribed amplitude is provided to the outside circumferential part of the base plate 2. Vanes 3 are fixed to the outside circumference of the cylindrical body 10. The buffer device 11 such as spring which controls the rapid vertical movement of the cylindrical body 10 is provided between the base plate 2 and the cylindrical body 10. The force which acts on control rods 5 is transmitted through the vanes 3 to the cylindrical body 10 even if the abnormal force acts on the control rods 5 when the control rods 5 receive resistance in guide pipes by a certain cause. The cylindrical body 10 is gently moved relative to the base plate 2 by the buffer effect of the device 11. The speed of inserting the cylindrical body to the fuel rod 5 assembly is thereby increased and the time for control is shortened.

Title: Air sensor for detecting position
Inventor: FURUKI TOKUO
IPC: G01V9/00
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To stably detect a position even if the surface to be detected of a work is not uniform by retreating against the urging force of a second spring when a probe pin is pressed by an object to be detected, closing a nozzle discharge port that is constantly open, and opening air from a nozzle that is constantly sealed. SOLUTION: The base edge part of a second spring 22 for urging a probe pin 21 forward touches one portion of a nozzle 19, clearance C is successively narrowed when work allows the probe pin 21 to retreat, and the outlet of a nozzle air passage 18 is narrowed. Furthermore, when the probe pin 21 is pressed, the outlet of the nozzle air passage 18 closes and at the same time the nozzle 19 is allowed to retreat against the energizing force of a first spring 20. When the work does not touch the pin 22 or the travel amount of the pin 21 exists in a dead zone, a pressure switch 15 does not perform detection. When the travel amount enters a sensitive zone, the clearance C is narrowed and the pressure switch 15 is turned on. Furthermore, when the pin 21 retreats, the nozzle 19 also retreats for preventing the pin 21 from being broken.

Title: Ink jet head
Inventor: TAKAHASHI MASAHIRO
IPC: B41J2/055
Filed: 1985-10-18
Abstract: PURPOSE:To achieve the high speed of ink jet with low noise and little residual vibration in a jet chamber, by a method wherein elastic plates and piezoelectric elements are provided onto both sides of an ink jet chamber and an ink jet head is driven by uniform force. CONSTITUTION:Elastic plates 2 are stuck onto both sides of an ink jet chamber 1 and further piezoelectric elements are stuck thereonto. Then, when voltage pulses are simultaneously impressed onto both piezoelectric elements 3, a pressure wave is generated in the ink jet chamber 1 because of the deflection of piezoelectric elements 3 and elastic plates 2, an ink drop being jetted from an orifice 4 and ink is supplied from an ink supply passage 6. Because left and right two sheets of piezoelectric elements 3 are simultaneously driven when this pressure wave is generated, the impulse waves to the head are cancelled. Thus, stable high speed of ink jet with low noise and little residual vibration in the ink jet chamber can be performed.

Title: Spring washer
Inventor: AIDA EIKO
IPC: F16B43/00
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To provide a spring washer which can reliably prevent loosening of a male screw against a female screw. SOLUTION: A spring washer relatively rotates around a screw shaft when a male screw screws into a female screw, while being sandwiched between two members which are adjacent to each other along the screw shaft. A slope surface 4c' of a one-end-side overlapping part 4c which connects to a one end face 4a slopes toward an orthogonal face of the screw shaft in such a manner that it gradually goes to the screwing direction of the male screw into the female screw along the screw shaft as separating from the one end face 4a. A slope surface 4d' of another-endside overlapping part 4d which connects to another end face 4b slopes toward an orthogonal face of the screw shaft in such a manner that it gradually goes to the screwing direction of the male screw into the female screw along the screw shaft as going to the other end face 4b.  When the male screw screws into the female screw, the one-end-side overlapping part 4c and the other-end-side overlapping part 4d are relatively rotatable in a peripheral direction of the screw shaft in such a state that they touch each other via the slope faces 4c', 4d', thereby increasing an overlapping area viewed from the screw shaft direction.

Title: Nonaqueous electrolyte secondary battery and manufacture of positive electrode active material used therefor
Inventor: SAITO SATORU
IPC: H01M10/052
Filed: 1988-09-19
Abstract: PURPOSE:To make discharge voltage higher, energy density larger, and charge and discharge cycle life longer by using mixed crystals of electrolytic manganese dioxide and chemically synthesized manganese dioxide as a positive electrode active material. CONSTITUTION:In a nonaqueous electrolyte secondary battery using lithium or lithium alloy for a negative electrode, mixed crystals of electrolytic manganese dioxide and chemically synthesized manganese dioxide are used as a positive electrode active material. Electrolytic manganese dioxide and chemically synthesized manganese dioxide have different particle sizes. Therefore, when these two kinds of manganese dioxide are mixed, the smaller diameter particles are dispersed among the larger diameter particles so that good contact can be obtained between the manganese dioxide particles as compared to the case where a single kind is used. Accordingly, most of the manganese dioxide is used for the battery reaction during charge and discharge so that a battery with a large discharge capacity can be obtained. Thus, higher discharge voltage, larger energy density, and longer charge and discharge cycle life can be achieved.

IPC: H01L21/027
Filed: 1990-09-05
Abstract: PURPOSE:To enable drawing time to be reduced by memorizing distortion coefficients on a plurality of grid points which are used for correcting distortion of patterns within each divided section of a drawing region at each same address of a plurality of memories. CONSTITUTION:A specified amount of drawing data is stored in a drawing data memory 8 from a magnetic disk according to a command of a control device 7 previously. Before drawing a pattern, a deflection distortion correction coefficient at each grid point of fields which are divided in grid shape obtained from mark detection and interpolation method is stored in memories 9A-9C. In this case, the same deflection distortion correction coefficient is stored at a negative address with one X address for the memory 9B for an address of the memory 9A and is stored at a negative address with one X address and one Y address for the memory 9C, thus enabling needed plurality of deflection distortion correction coefficients to be called from each memory by performing addressing once for one pattern to be drawn. Therefore, time required for recalling in entire drawing can be reduced.
