Patent JP-H1183377-A (JP)
Title: Heat exchanger
Inventor: KUBOTA ETSURO
IPC: F28F9/02
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To reduce the number of components, reduce cost and facilitate their assembling work. SOLUTION: A heat exchanger is comprised of a pair of header pipes 1a, 1b and heat exchanging pipes 2 arranged between these header pipes 1a, 1b. End portions of the header pipes 1a, 1b are press collapsed and connected to each other to form a flat section 6, and, at the same time, they are brazed to close the connected portions. With such an arrangement as above, since the header pipes 1a, 1b can be air-tightly held, it is not necessary to apply any end cap. Correspondingly, the number of components can be reduced.

Title: Manufacture of modified wood
Inventor: OCHIAI TAKESHI
IPC: B27K3/16
Filed: 1989-09-29
Abstract: PURPOSE:To contrive to improve flame retardancy by a method wherein insoluble inorganic compound is formed in wood and the formation of the crystal of said compound and its growing speed and crystal form at grain growth are controlled. CONSTITUTION:By immersing wood in first water solution containing water-soluble calcium salt and second water solution, which produces insoluble calcium compound through chemical reaction with said water-soluble calcium salt, so as to produce insoluble calcium compound in the wood. Next, by immersing the resultant wood in water or low concentration metal salt water solution, the insoluble calcium compound is crystallized out on the surface of the wood so as to produce highly crystalline mineral film. Accordingly, since the interior of the wood and outside air is separated from each other by the mineral film, oxygen is prevented from supplying to the organic matter structure in the interior of the wood. Thus, good flame retardancy is obtained and semi- noncombustibility is attained. At the same time, the merit of the wood or its original lightweight, high hygroscopicity and excellent workability are also maintained.

Title: Radiation pickup device
Inventor: HORI NAOYUKI
IPC: H01L31/09
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily avoid the degradation of picture quality due to the unevenness of the intensity of a sensor detection signal. SOLUTION: In this X-ray pickup device, an X-ray detection element corresponding to the same image pickup point of a specimen M is continuously shifted by inching an X-ray sensor 2 shaped like a panel with X and Y inching sections 4 and 5. Meanwhile, the X-ray camera device includes a structure where a displacement between images associated with the small movement of the X-ray sensor 2 shaped like a panel is inhibited according to the position correspondence relation between the sensor 2 and the specimen M detected by a position correspondence relation detecting section 18. As a result, five different X-ray detection elements are used evenly for each image pickup point of the specimen M, and the unevenness of detection properties on the detection surface is mitigated to lower the influence of the fluctuation.  Consequently, the degradation of picture quality of X-ray images due to the unevenness of the intensity of a detection signal can be avoided easily without causing the image slippage between images and degrading a space resolution.

Title: Electrophoresis apparatus
Inventor: MURAKAWA KATSUJI
IPC: G01N27/26
Filed: 1989-09-30
Abstract: PURPOSE:To obtain excellent reproducibility by simple, quick operations by providing at least two molecular-weight partitioning films in the order from the film for larger molecular weight or in the reverse order, and partitioning electrophoresis paths. CONSTITUTION:A migrating tank 4 is divided into a first chamber 4a, a second chamber 4b and a third chamber 4c with molecular-weight partitioning films 5 and 6. The surfaces of the films 5 and 6 face the chambers 4a, 4b and 4c, respectively. The dividing molecular weight of the film 5 is larger than the molecular weight of intended molecules 8. That of the film 6 is smaller. When an electric field is applied through electrodes 2 and 3, the molecules in the chamber 4a are migrated in the direction 3 from the electrode 2 to the electrode 3. Only the molecules smaller than the partitioned molecular weight of the film 5 pass the film 5 and move into the chamber 4b. Only the molecules which are smaller than that of the film 6 move into the chamber 4c. As a result, the intended molecules 8 are isolated in the chamber 4b. The molecules 9 which are larger than the partitioned molecular weight is separated in the chamber 4a. The molecules 10 smaller than the molecular weight are separated in the chamber 4c. Thus, the intended molecules can be separated and separately collected simply and quickly.

Inventor: GILLARD HERVE PAUL ROLLAND
IPC: G01N27/84
Filed: 1994-10-20
Abstract: PURPOSE: To improve the reliability of piece inspection by exposing a detected object material under proper illumination suited for a selected indicator. CONSTITUTION: A piece 11 is preprocessed by utilizing a prescription giving a contrast capable of indicating clearly cracks compared with the surface of a piece 11 (detected object material). In the case of fluorescent liquid penetrant flaw inspection, the prescription is a fluorescent pigment radiating hard under the ultraviolet ray, and the background of the surface is left to be dark. The piece 11 is exposed under the proper illumination suited for the selected indicator, i.e., in the luminescent liquid penetrant flaw inspection, the piece 11 is exposed to the ultraviolet ray from an illuminator 10. Next, the piece 11 is optically detected by TV camera 12 having the extremely high sensitivity to the low level light to be electronically processed. A picture image thus obtained is processed by a picture image processing system 13 such as a computer for example.  Thus, the reliability of the piece inspection by the liquid penetrant flaw inspection, particularly a fluorescent liquid penetrant inspection can be improved.

Filed: 1986-10-29
Abstract: PURPOSE:To reduce noises during the operation of devices in a mechanical system including a motor by supplying high voltage on acceleration and on deceleration and low voltage on the state of constant-speed revolution. CONSTITUTION:When starting a stepping motor 4, a changeover circuit 3 selectively feeds supply voltage V1 through a power circuit 1 to the stepping motor 4. A winding drive circuit 5 turns winding currents to each winding for the stepping motor 4 ON-OFF by a predetermined excitation sequence. When the stepping motor 4 is brought to the state of constant-speed revolution, the changeover circuit 3 selectively feeds supply voltage V2 through a power circuit 2 to the stepping motor 4. Supply voltage V2 is set at a value lower than supply voltage V1. Accordingly, the torque of the stepping motor 4 is made lower than that at the time of starting under the state of constant-speed revolution.
