Title: Warming device of reactor residual heat removal system
Inventor: CHIBA YOSHINORI
IPC: G21C19/307
Filed: 1989-04-28
Abstract: PURPOSE:To prevent carrying-in of radioactivity into a residual heat removal system and allow the device to reduce a load of water treatment after warming completion by allowing the device to warm up the residual heat removal system with the use of reactor water purified and heated by a reactor coolant purification system. CONSTITUTION:Since a reactor residual heat removal system 14 is warmed up during reactor stop, hot water purified by a reactor coolant purification system 15 is branched from the outlet of the purification system 15 to increase pressure by a residual heat removal pump 2 through a branched conduit 7 in which a valve is provided on the way so as to introduce to a residual heat removal heat exchanger 3. And reactor water warming up the removal system 14 is allowed to flow in inlet tubing 10 and outlet tubing 10 of a non-regenerative heat exchanger 19 through a branched conduit 8 from the outlet of the heat exchanger 3 to introduce to a reactor pressure vessel 12 after the reactor water is purified by a filtration demineralizer 11. As the result, since the removal system 14 is warmed up by the reactor water purified and heated by the purification system 15, carrying-in of radioactivity into the removal system 14 is prevented and further warming is performed without exhaust of the reacter water outside the removal system 14, a load of water treatment can be reduced after warming completion.

Title: High frequency quadrupole accelerator of external resonance type
Inventor: ITO JUNYA
IPC: H05H9/00
Filed: 1993-05-10
Abstract: PURPOSE:To provide an external resonance type high frequency quadrupole accelerator in which thermal deformation of each component member can be suppressed. CONSTITUTION:An external resonance type high frequency quadrupole accelerator concerned is composed of a quadrupole electrode 1, unitary secondary coil 2, and a primary coil 3. The unitary secondary coil 2 is so structured that eight conductive cooling pipes 2A processed into a channel shape are laid in the same direction and a conductive plate material 2B furnished internally with a cooling liquid path is joined with each end part of these cooling pipes 2A. The primary coil 3 has such a structure that a conductive cooling pipe is processed into a circular shape. When the cooling liquid is fed flowing through the cooling pipes and the cooling paths in the plate materials, the unit secondary coil 2 and primary coil 3 are cooled, and thereby thermal deformation is suppressed. This permits variation of the resonance frequency and suppressing of degradation of the impedance matching of resonance circuit with the power supply line.

Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To make the states of soldered junctions observable by extending metallic posts outward from a group of electrode pads and the area surrounded by the electrode pads and forming solder bumps or solder balls around a chip. SOLUTION: Openings K are formed through a passivation film 3 and an insulating resin layer for exposing a titanium nitride film and wiring layers 7 are formed in the openings K by performing Cu-plating.

Title: Surface inspection method for electrophotographic photosensitive drum
Inventor: NAKAGAWA MICHIHIRO
IPC: G06T7/00
Filed: 1995-05-02
Abstract: PURPOSE: To enhance the inspection accuracy without requiring any prestage processing by turning an object in the circumferential direction, mapping the image information for single turn and comparing the mapped image information with that mapped similarly on the second time. CONSTITUTION: A electrophotographic photosensitive drum 3 secured to a jig is projected with light from a light source 2 while being turned in the circumferential direction by means of a motor and a CCD camera 1 is set at a regular reflection position on the optical axis thereof. First time measurement is then carried out and an image signal picked up through the CCD camera 1 is subjected to A/D conversion and mapped on the developed plane of the drum 3. It is then subjected to an external effect, e.g. aeration, and second time measurement is carried out under same conditions and the maps obtained through both measurements are superposed thus determining the difference. More specifically, rattling and rotational fluctuation due to jig and motor are taken into account and a frame is set in the X and Y directions.  If identical voltage signals are present within the frame, it is decided that the voltage signals represent a defect at a same point. With such arrangement, a defect on the surface of the drum 3 can be discriminated definitely from a defect detected erroneously due to dust on the periphery without requiring any prestage processing, e.g. neutralization.

Title: Method for analyzing dextrin in plating liquid and liquid chromatograph
Inventor: IWABUCHI HITOSHI
IPC: G01N30/14
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To selectively detect only dextrin included in a plating liquid and accurately measure a molecular weight distribution by adding to a heavy metal in the plating liquid sodium carbonate of a specific concentration, thereby solidifying the heavy metal beforehand, and precipitating the heavy metal with the use of a centrifugal separator. SOLUTION: 9 ml of 1 M sodium carbonate is added to 1 ml sample and permeated well, which is centrifugally separated at 10000 rpm, whereby 1/1800 of heavy metals are precipitated. Contained dextrin remains in a supernatant liquid. For preventing deterioration of a separation column, 1N hydrochloric acid of an equivalent amount is added to the supernatant liquid to change from a neutral region to a weak acid, whereby an optimum sample condition for liquid chromatograph is obtained. Although carbon dioxide included in a test solution is emitted in this case, results with good reproducibility can be obtained if the carbon dioxide is fully eliminated before injected to the liquid chromatograph.
