Patent JP-S6015615-A (JP)
Title: Optical device
Inventor: MATSUMURA ISAO
IPC: G02B13/08
Filed: 1983-07-07
Abstract: PURPOSE:To generate an optional cylinder power easily in the position of the pupil of an optical system to be examined by adding a variable power projection optical system. CONSTITUTION:If the projection magnification is set to unmagnification, a power equivalent to a cylinder lens 14 is obtained in the position of a pupil 11 by the cylinder lens 14 placed near a position 13 where the pupil 11 of the optical system to be examined is formed an image with unmagnification by a projection lens 12. If the projection magnification is changed, a power M<2>XP is obtained in the position of a pupil 21 by a cylinder lens 24 which has a power P and is placed near a position 23 where the pupil 21 of the optical system to be examined is formed on image with 1/M magnifications by a projection lens 22. When the magnifying optical system is set by the variable power projection optical system in this manner, the cylinder power is raised, and the precision can be improved partially in a low-precision cross angle position. The cylinder power can be reduced when a reducing optical system is set.

Title: Thyristor converter
Inventor: KOBAYASHI ATSUO
IPC: H02M1/092
Filed: 1978-10-09
Abstract: PURPOSE: To improve responsibility of a thyristor converter by triggering by gate control light signals a photo thyristor having a gate part which gives light signals of  two guides while triggering it forcedly by light signals of an overvoltage detecting  circuit equipped in parallel with the photothyristor.  
     CONSTITUTION: A gate control signal produced by a signal generator 2 is converted into a light signal by a light emitting device 3 and this light signal is supplied to a photo thyristor 1 through a light guide 4. The photo thyristor 1 turns on and the thyristor converter is brought into prescribed motion. On the other hand, if a forward overvoltage is added to the photo thyristor 1 during operation of the thyristor conveter or during the floating, the prescribed current is applied to a light emitting device 6 and a light signal produces. This light signal makes a trigger signal given to the gate part of the photo thyristor 1 through a light guide 5, turns on the photo thyristor 1 and protects the photo thyristor form the forward overvoltage.

Filed: 1987-05-21
Abstract: PURPOSE:To form a small and low-priced oscillatory type axial air-gap type motor by eliminating at least one coil of a coreless flat armature and by providing a metal weight plate for making said armature eccentric. CONSTITUTION:Motor casings 6, 7 serving also as stator yokes are fitted with bearings 8, 9, by which the rotating shaft 2' of a coreless flat armature 21 constituting a rotor is supported. Said coreless flat armature 21 lacks one of three armatures which it usually has, two air-core type armature coils 12-1 and 12-2 are arranged at a pitch of 120 deg. in said armature 21, and their outer peripheral parts are molded into an integral body by plastics so that said armature is formed into a discoidal shape. A metal weight plate 35 for making said armature 21 eccentric is immovably provided on the surface on the side opposite to the field magnet 14 of said flat armature 21. As the coreless flat armature 21 is eccentric and oscillates while revolving, an oscillatory sound can be generated and a thickness can be thinned even if any particular revolving plate is not provided.

Filed: 1990-05-14
Abstract: PURPOSE:To improve accuracy in location with simple constitution, in a small parts picking and placing device, by providing a turning member on the rotary center shaft of a turning arm and a locating tapered pin on the turning member so that the tapered pin is fitted in an opposed tapered hole for location. CONSTITUTION:A straight advancing cylinder 12 for lift is set to the upper limit position and a straight advancing cylinder 1 for turn is advanced straight from one end to the other end to turn the rotary center shaft 8. Then, a turning arm 21 is turned and a turning member 10 supporting a tapered pin 18 is also turned. Thus, the tapered pin 18 is moved from a tapered hole 19a in an indexing plate 26 onto a tapered hole 19b. When the cylinder 12 for lift is lowered until a nut 14 abuts against an abutting plate 13, the tapered pin 18 is fitted in the tapered hole 19b during that process so as to be located. Thus, accuracy in location can be improved by simple constitution.

Title: Method for forming barrier of plasma display panel
Inventor: OOKUBO SAKURAKO
IPC: H01J11/22
Filed: 1993-04-30
Abstract: PURPOSE:To form a barrier with a desired pattern without causing peeling of a subtractive masking layer during a subtractive process. CONSTITUTION:A subtractive masking layer 3 is broadened at both ends. Even if grounding of a glass paste 2 located beneath both ends of the masking layer 3 proceeds during a subtractive process, the masking layer 3 is not peeled since both ends of the masking layer 3 are in close contact with the glass paste 2 over a wide area. The subtractive process is carried out with the overall masking layer 3 kept in close contact with the glass plate 2, so a barrier 2a with a good pattern can be formed.

Filed: 1985-06-07
Abstract: PURPOSE:To improve production efficiency by forming the end diameter of pestles smaller than the hole diameter of a mortar and disposing a sliding contact part which can be freely slidably inserted into the mortar hole to the lower pestle. CONSTITUTION:Powder is packed into the hole 2 of the mortar 1 and is subjected to compression molding by the upper and lower pestles 8, 3. The end diameter of the pestles 8, 3 is formed smaller than the diameter of the mortar hole 2 to constitute a compressing part. The sliding contact part 5 to be freely slidably inserted into the mortar hole 2 is disposed below the compressing part of the lower pestle 3 so as to have the diameter slightly smaller than the hole diameter of the mortar. The powder packed into the hole 2 is compression-molded by the compressing part 4 of the upper and lower pestles 8, 3 then the lower pestle 3 is raised after the rise of the upper pestle 8. The sliding contact part 5 of the lower pestle 3 acts to scrape off the unnecessary powder in the mortar hole 2. Since the mortar hole 2 is thereby cleaned, the stop of the molding machine is eliminated and the production efficiency is improved.
