Title: Dielectric ceramic
Inventor: TAKASE MASAKI
IPC: H01P7/10
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To impart excellent dielectric properties, high specific inductive capacity (ξr), large unloaded quality factor (Qu) and a small absolute value of the temperature factor (τt) of the resonance frequency (f0) by relating several kinds of metal oxides as the constitution components to a specific composition. SOLUTION: The objective dielectric ceramics are represented by the composition formula [(uLi2O-vNa2O)-wSm2O3-xCaO-yTiO2] and are defined as follows: 0<u<40, 0<v<40, 0<u+v<=40, 0<w<=30, 0<x<=40, 0<7<=80 where u+v+w+x+y=100 (mol.%). The excellent dielectric properties are developed, when any of Ca1-xSm2x/3TiO3, Li1/2Sm1/2TiO3 and Na1/2Sm1/2TiO3 take a solid solution structure. When a part of Ti4+ are substituted with Ga3+ or Al3+, Qu×f0 is further increased, in addition, τt becomes controllable by altering the ratio of quantities of Li and Na of which the signs of τt are different from each other.

IPC: H01F10/28
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To attain excellent high speed rotation stability without generating vibration even in the use under high speed rotation by making the ratio of Young's module to density in a substrate of an aluminum alloy or the like equal, to above a specific value in a magnetic disk. SOLUTION: In the magnetic disk used under high speed rotation, the substrate of the aluminum alloy or the like is formed so that the ratio E/p of Young's module E (kg/mm<2> ) to density (ρ) (g/cm<3> ) becomes 22800. The ratio E/ρ is made >=2800 by increasing the ratio E/ p of the substrate itself or forming a surface treating film to increase the E/ρ as the whole substrate in combination of the substrate and the surface treating film. By making the ratio E/ρof Young's module to density (ρ) in the substrate of the magnetic disk >=2800 in this way, vibration due to resonance is not generated even in the high speed rotation of >=1000rpm.

Title: Stroboscope controller for camera
Inventor: TAKAMI SATOSHI
IPC: G03B7/16
Filed: 1989-10-06
Abstract: PURPOSE:To eliminate misphotographing caused by the abnormal irradiation of a stroboscope and to realize the normal photographing by inhibiting the light emission of the incorporated stroboscope when the light emission part of the incorporated stroboscope is not moved to a regular light emission position and executing the photographing with the aid of a proper exposure value under such a state. CONSTITUTION:The light emission part 12 of the incorporated stroboscope is supported to the upper part of a camera main body 10 by a lever 13 being a supporting mechanism so that it can be moved between the housing position of a housing part 10a and the light emission position which projects from the housing part 10a. By the movement, the rotation of the motor 16 of the stroboscope is transmitted to the sector gear 14 of the lever 13 through gears 17 and 15 and it is informed to a camera control circuit through limit switches 18 and 19 that the light emission part 12 arrives at the housing position and the light emission position. When the light emission part 12 does not arrive at the light emission position when the incorporated stroboscope is used, the emission of the light is stopped by the control circuit and the photographing is executed by the proper exposure value under a state where light is not emitted.

Title: Medical x-ray tube device
Inventor: IKEJIMA TETSUHIKO
IPC: H05G1/02
Filed: 1990-09-29
Abstract: PURPOSE:To improve the cooling efficiency in an X-ray tube container by circulating insulation oil existing in both in an outer container and a high pressure tank between them through a heat exchanger. CONSTITUTION:A heat exchanger 4 is provided between an X-ray tube container 1 and a high pressure tank 2, so insulation oil sent from an anode side 1a of a container 1 between X-rays passes through a hose 7 in a cable 3 to reach the heat exchanger 4. Insulation oil cooled at the heat exchanger 4 gets into the high pressure tank 2, so insulation oil in the high pressure tank 2 is sent to a cathode side 1c of the X-ray tube container 1. Because the heat exchanger 4 can be installed close to the high pressure tank 2, so the one of a large size can be used to increase the quantity of insulation oil circulating at a time. The cooling efficiency of the insulation oil can thus be improved.
