Abstract: PURPOSE:To improve accuracy of orthogonal crossing of hyperbolic faces and relative distances among electrodes by making opposite faces of two pairs of electrodes having hyperbolic faces, to be flat and also the contact faces, between a member holding electrode and said electrode to be flat. CONSTITUTION:Two pairs of electrode rods 22 having the hyperbolic surfaces and the flat opposite surfaces 24 are opposedly arranged along the ion propagation path while the face of the supporting ring 26 making contact with the electrode rods 22 are formed flat while being fixed so that the extension lines of the focal points of the hyperboilic lines, which are formed by the surface shape of each electrode rod 22 may orthogonally cross the origin O in order to form a quadripole mass spectrometer. Accordingly, the axes of the hyperbolic surfaces can be made to cross accurately orthogonally besides the relative distances 2 ro among the electrode rods can be held with high accuracy while auxiliary electrodes 34 are inserted into four corners between the supporting ring 26 and the electrode rods 22 in order to absorb emitted ions thus enabling to get rid of turbulence in an electric field.

Abstract: PROBLEM TO BE SOLVED: To reduce an area taken by a storing means for holding a voxel space, suppress voting errors and extract color information. SOLUTION: A voxel space generating part 11 selects a plurality of images obtained, by photographing the entire shape of a subject as a contour image among photographed images, generates voxel space information by using the contour information of a subject area on the contour images and stores the voxel space information in an information storage part 15. A voxel generating part 12 defines the prescribed number of images as a reference image among a plurality of images and their adjacent images as reference images, generates a voxel which is a unit three-dimensional space going through a characteristic point in a voxel space about the characteristic point on the reference images and stores the voxel and color information C of the original characteristic point in the part 15.  A voxel information comparing part 13 extends a projection line from the generated voxel toward each reference image and compares the color information of an intersection with the reference image with the information C.

Abstract: PURPOSE:To simplify a construction by detecting an output of a sensor element composed of a fluorescent fiber containing a fluorescent substance inside and by specifying the length of the fiber. CONSTITUTION:A fluorescent substance is added to the inside of the core of a plastic optical fiber 1 using methyl methacrylate resin as a core material and methacrylate fluoride resin as a sheath material, and the length l of the fiber 1 thus prepared is made to be not larger than a length l0 defined by a formula I, while a light power meter 2 is connected to the fiber 1.

Title: Optical recording method
Inventor: AOI TOSHIKI
IPC: G11B7/246
Filed: 1984-09-21
Abstract: PURPOSE:To enhance sensitivity and a S/N ratio and to reduce an error rate by improving a surface layer, in performing optical recording by irradiating writing light to form a pit, by forming the pit as a recessed part in such a state that surface layer is not substantially destructed. CONSTITUTION:A surface layer is formed of a hard film with high m.p. so as not to form a pit by light irradiated for a definite time or less.

Abstract: PROBLEM TO BE SOLVED: To suppress temperature rise of a printer head without sacrifice of print efficiency of a printer. SOLUTION: The dot impact type printer comprises means 2 for detecting the temperature of a print head, and a control section 4 for altering the number of head pins to be driven depending on the temperature state of detected print head. When the temperature of the print head rises, the control section 4 divides the head pins to be driven and performs printing in both directions. Furthermore, the control section 4 previously calculates the number of print dots for each pin and performs the print operation while dividing into a plurality of times thus preventing temperature rise only of specific pins.

Title: Method for moving-hardening of bar-like work
Inventor: NAGAO TAKEHIKO
IPC: C21D1/10
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To execute moving-hardening to the outer peripheral surface of a bar-like work arranged with a larger diameter part at part in the axial direction into a uniform depth to the vicinity of the large diameter part. SOLUTION: A complex coil composed of a primary coil 21 for induction- heating the outer peripheral surface of the bar-like work 10 and a secondary coil 22 for cancelling part of the current flowing in the primary coil 21 with an induction current from the primary coil 21 is used as the induction heating coil 20. The induction heating coil 20 is shifted in a state the front part of the secondary coil 22 is projecting toward the front part of the primary coil 21 to heat the outer peripheral surface of the bar-like work 10 sequentially.

Title: Combustion box
Inventor: MIZUNO MINORU
IPC: F24H9/02
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To avoid generation of abnormal sounds caused by expansion and contraction of a combustion box formed by engaging a claw part provided on and protruding from a side edge of a box main body with a slit formed in a side plate. SOLUTION: A notch 40c is formed in a part between claw parts 40a on a side edge of a box main body 40 excepting a shoulder part 40b in a vicinity of the claw part in contact with a side plate 41. A clearance is formed between the side plate 41 and the side edge of the box main body 40 by the notch 40c so that abnormal sounds caused by rubbing the side plate 41 and the side edge with each other at the time of expansion and contraction of the combustion box 40 are prevented from being generated. Because the shoulder part 40b comes in contact with the side plate 41 but the shoulder part 40b is positioned in a vicinity of the claw part 40a engaged with the slit 41a in the side plate 41, the shoulder part 40b makes almost no dislocation against the side plate 41 so that the abnormal sounds are hardly generated by rubbing of the shoulder part 40b and the side plate 41 with each other.  Or, a flange opposite to the side plate 41 may be formed on the side edge of the box main body 40 and a bead may be formed on either one of the flange and the side plate in such a manner as to swell toward another.
