Title: Ring element type fuel spacer
Inventor: OKUBO KAZUTOSHI
IPC: G21C3/344
Filed: 1989-03-30
Abstract: PURPOSE:To surely protect the ring elements themselves from deformation and failure by boring cut windows for insertion of slender elastic holding parts to the ring elements in the axial line direction thereof and extensibly providing upper inward embossing parts and lower inward embossing parts thereto in the diametral direction. CONSTITUTION:Looped springs 1 are held supported by the spring supporting plate parts 2j of the ring elements 2 disposed between the upper and lower inward embossing parts 2d and 2e in the state in which the transfer of the springs 1 is completed. The ring elements 2 in adjacent contact with each other in the circumscribing state of the ring elements 2 are then welded by welding means respectively on the upper side and lower side to form welded parts 3a, 3b. Fuel rods are inserted into the ring elements 2 formed in such a manner. The fuel rods are then pressed to the embossing parts 2d, 2e if the rods receive the pressing force of a certain level or above when the fuel rods, etc., are laterally oscillated by an earthquake. The lateral movement of the fuel rods beyond the above is prevented and, therefore, the looped springs 1 are protected without receiving the undue external forces.

Title: Vessel with enclosing lid
Inventor: HAYASHI YOSHIHIKO
IPC: B65D43/06
Filed: 1994-03-25
Abstract: PURPOSE:To provide a plastic vessel with lid having a highly sealing property which prevents fluid contents.from flowing out. CONSTITUTION:A circular bend 202 with a hook-form sectional shape at the upper side of a vessel and a circular bend 212 with a hook-form sectional shape of the lid 211 are vertically pressed to fit together. The fitting protrusion 215 at the outer edge side face is fitted to the fitting recess 205 to prevent the lid from slipping off. Since the circular protrusive corner 214a of the circular bend 212 is made to have a little larger diameter D2 than the inner diameter d2 of the contact part of the taper face 204 on the inner edge side face of the vessel, the circular protrusive corner 214a is joined with pressure by the fitting pressure of the circular bends and these are closely joined with the circular linear contact and hence, highly hermetical sealing can be retained.

Title: Spacer for optical fiber cable
Inventor: MASUDA YUICHI
IPC: G02B6/44
Filed: 1987-04-01
Abstract: PURPOSE:To extend the life of an optical fiber by forming the groove of a spacer for housing the optical fiber to the structure in which the groove is perpendicular to the central face of the groove running the center in the depth direction of the groove and is deeper than the perpendicular central face of the groove running the center of the spacer.

Title: Momentary break processing method
IPC: G06F12/16
Filed: 1992-04-01
Abstract: PURPOSE:To reduce the capacity of a backup capacitor as much as possible and to minimize software processing by driving a CPU with a low source voltage, placing the CPU in a standby state before the lowest operating voltage, and performing backup operation up to the lowest holding voltage of a RAM. CONSTITUTION:A switch circuit 4 whose ON resistance is equal to 0OMEGA normally turns ON to supply a source voltage VIN to the CPU 1. When the source voltage VIN drops, the output of a voltage detecting circuit 3 falls to a low level, the switch circuit 4 turns OFF to place the CPU 1 in the standby state, and the CPU is backed up by the capacitor 5. When the VIN recovers before the CPU 1 is reset, the switch circuit 4 turns ON and then the standby state is released. When the voltage across the capacitor 5 drops and the source voltage VIN recovers after the CPU 1 is reset by the voltage detecting circuit 2, the switch circuit 4 turns ON first to apply the VIN to the CPU 1; and then an interruption signal is sent and the resetting is released successively.

IPC: G03G15/22
Filed: 1990-03-28
Abstract: PURPOSE:To attain the aging stability of image quality and to prevent heat deterioration of powder ink by making a fixing device for an ink layer which is used at a stage for reproducing an ink sheet non-contact with the ink sheet and providing a shielding plate. CONSTITUTION:The void part 8 of the ink layer and the adhesion part 9 of the ink layer are formed on the ink sheet 1 by forming an image. The powder ink 11 which comes in contact with the void part 8 adheres to an insulating supporting body 2 with the force of static electricity by vias Vb which acts on the in layer, but the powder ink 11 which comes in contact with the powder ink adhering to the adhesion part 9 and the insulating supporting body 2 does not adhere because of the escape of charges, so that the powder ink is supplied only to the void part 8. The ink sheet 1 to which the powder ink is supplied is conveyed across the shielding plate 15 which prevents heat from being propagated to a powder ink supply part and the ink is fixed on the ink sheet at the part of a non-contact thermal fixing machine 14. Thus, the accumulated quantity of heat is reduced, the ink layer does not move to the contact part in a fixing part, and the image quality is prevented from being deteriorated.

Title: Ink fountain roller in printing press
Inventor: MITAMURA MITSURU
IPC: B41F31/04
Filed: 1986-04-07
Abstract: PURPOSE:To stabilize the thickness of an ink film by certainly performing the adjustment of a zero point, by preventing the variation of a gap by a reaction force due to the thickness of the ink film generated when the gap is squeezed narrowly by bringing an ink fountain roller to a pre-load state by bending a beam and the ink fountain roller. CONSTITUTION:When a beam 26 is bent by rotating the screw of a press device 23, an ink fountain roller 1 is also bent through a center receiving shoe 21 to become a pre-load applied state. The pressing force of the press device 23 is made relatively larger than the pressure of an ink film thickness generated in an ink metering key apparatus 18 and this reaction force is absorbed by the above-mentioned pre-load. As mentioned above, if a screw device 8 is rotated by an electromotor 14 while the ink fountain roller 1 is bent to hold the pre-load state to finely move a rectangular ink metering key 7 and the edge 7a of said key 7 is contacted with the surface of the ink fountain roller 1 and the position of a zero point is measured and displayed by a potentiometer 17, when the ink fountain roller 1a rotates to an (a)-direction, the change in the gap between the ink metering edge 7a and the surface of the roller 1 by the reaction force of the ink film thickness is eliminated and the adjustment of the zero point can be performed simply and certainly.

Abstract: PURPOSE: To improve a magnetic flaw detector in reliability and to obtain a ready  judgment by applying a current to a calibration coil adjacent to a portion of the detection coil.  
     CONSTITUTION: A traveling rope 1 under test, is passed through holes of a pair of pole pieces 4a and 4b of an exciter 2, and a given section of the rope is magnetized  by the electromagnetic force of an exciter body 3 comprising an electromagnetic  coil. The power for the electromagnetic coil of the exciter body 3 is supplied from a  power source 5 comprising a transformer 5a, rectifier 5b, and smoothing circuit 5c.  Thus, if the rope 1 has such damage as broken wires, the magnetic flux in the rope  1 is disordered, so that a leakage flux is produced on the surface. The interlinkage  of the leakage flux to a detection coil 6 around the circumference of the rope 1  causes a minute voltage to be induced in the detection coil 6. The induced voltage  is amplified in an amplifying unit 7, and recorded as a damage signal on a recorder  8.
