Title: Magnetic unit pole piece
Inventor: TSUNO KATSUSHIGE
IPC: G01R33/383
Filed: 1978-12-19
Abstract: PURPOSE: To greatly enhance magnetic field uniformity in pole pieces having a logarithmically curved surface by using a special angle θ f  between its plane and the point of contact.  
     CONSTITUTION: A pole piece 1 is on core 3 spaced by pure iron spacer 2. The leading edge plane 1a with diameter d f  faces the opposing pole piece. Outer periphery near the plane 1a is machined in the logarithmically curved surface 1b which is specially calculated, and the angle θ f  formed by two faces is set to about 2.5W4°. In machining, when the angle θ f  has reached a specified value, the curved face 1b is cut into either plane face, or conical plane 1c having an angle θ f . This structure allows magnetic field distribution to have small and stabilized 2nd and 4th coefficients and each aberration to have minimum dependency on Z. The obtained magnetic field is easy to correct by a device such as a shim coil, thus resulting in an  equipment with a highly uniform megnetic field.

Title: Fixing method of solid-state laser oscillator chamber
Inventor: MORIWAKI MAKOTO
IPC: H01S3/08
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To eliminate the deflection or deformation of a mounting base caused by a thermal expansion coefficient so as to dispense with a realignment operation carried out for an optical axis, by a method wherein an oscillator chamber and the mounting base are fixed with fixing screws. SOLUTION: An oscillator chamber 4 is fixed to a mounting base 2 with two or more fixing screws 5 by screwing down only the one edge side of the oscillator chamber 4 in a light axial direction. Furthermore, a freely slidable mechanism 8 is mounted between the oscillator chamber 4 and the mounting base 2, and the oscillator chamber 4 is expanded only in the direction of an optical axis when the oscillator chamber 4 is thermally expanded, so that a mechanical vector is not applied to the mounting base 2, and the mounting base 2 is kept free from deflection or deformation. By this setup, the vector of the mounting base 2 generated downwards is eliminated, so that an oscillation mode can be restrained from getting out of position in the direction of a light axis or a laser beam can be restrained from varying in output power due to the deflection or deformation of the mounting base 2.

Title: Image reader
Inventor: KOYANAGI YOSHIHIRO
IPC: H04N1/04
Filed: 1989-06-21
Abstract: PURPOSE:To obtain picture information with a high precision by reading picture information on a scanned body while displacing photoelectric transducers, which are arranged at intervals of a prescribed length in the main scanning direction and are arranged in plural columns in the subscanning direction, in the subscanning direction. CONSTITUTION:Though a document A is shifted in the direction of an arrow Z orthogonal to the scan face at the time of reading the image, picture information on a main scanning line B is accurately read. That is, CCDs 44a to 44d are displaced in the subscanning direction of an arrow X by an eccentric cam 45, and the same effect that CCDs are arranged on one straight line is practically obtained. Thus, picture information on the main scanning line B is read in the state free from line deviation. Since a lens 46 as a common optical system is used to read picture information on the main scanning line B, the position of picture information read by CCDs 44a to 44d is not deviated, and the occurrence of drop-out of picture information or double read is prevented.

Title: Vertical pump device
Inventor: SASE TOSHIJI
IPC: F04D13/00
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To prevent vibration caused by pressure pulsation, etc., generated in operating a pump, from being propagated to the wall of a liquid tank by shielding the outer periphery of the pump below the water surface of the liquid tank, with a cylindrical shielding body in a pump device provided with a pump which is installed at the upper floor of the liquid tank, and provided with a suction port opened into the liquid tank. SOLUTION: When the operation of a pump is started, water sucked from a suction port 3 is fed to a discharge pipe 5 through a column pipe 11 and a discharge port 4. At this time, since the upper part of a pulsation propagation preventing pipe 7 is provided with an air communicating hole 8, the water surface in the pulsation propagation preventive pipe 7 is on the same level as the water surface 10 in a water tank 12. This operation causes pressure pulsation of frequency determined by the rotating speed of the pump 2, the blade number of an impeller and the vane number of guide vane. The pump 2 is vibrated by this pulsation and rotation to make water in the water tank 12 pulsate. This pulsation is propagated to the outside from the pump 2 but damped abutting on the pulsation propagation preventive pipe 7 to almost eliminate influence on the wall of the water tank 12.

Abstract: PURPOSE:To obtain an optical information recording medium having excellent durability and favorable recording characteristics, by composing a recording layer of a vapor- deposited film of an aluminum-based phthalocyanine compound, and performing heat mode bit forming type recording by semiconductor laser. CONSTITUTION:An aluminum-based phthalocyanine compound of the formula, wherein X is a halogen or hydroxyl and R is a halogen or hydrogen, has not only excellent durability but also higher reflectance and absorptivity as compared with those of other phthalocyanine derivatives.

Therefore, a heat mode bit forming type optical information recording medium can be constructed with a single coloring matter layer. An effective use of the optical information recording medium may be based on a system wherein recording of the heat mode bit forming type is carried out by using semiconductor laser light in a wavelength range of 600-900nm, and reading is carried out by detecting as a signal a difference in reflected light intensity between bit parts and other parts on irradiation of the medium with the same semiconductor laser light.
