Title: Line-type thermal transfer printer
Inventor: SHIMOJO TETSUJI
IPC: B41J17/36
Filed: 1986-11-21
Abstract: PURPOSE:To stabilize a back tension on an ink film and enhance transfer quality, by controlling a force for drawing out the ink film from an ink film payout roll by a controlling means. CONSTITUTION:An ink film 8 is drawn out from a roll 6 by a clamping and feeding force exerted by a platen 11 and a thermal head 1, and is taken up onto a roll 7. The ink film 8 is guided by flanges 61, 62. The flange 62 is supported on a frame 15 by a rotatable shaft, while a friction member 17 is pressed against the flange 61 with a predetermined pressure by a spring 18 through a friction member cover 16. With a lever 21 turned, an eccentric cam 20 is also rotated to move a spring seat 19 leftward or rightward, whereby a force for pressing the friction member 17 against the flange 61 can be arbitrarily changed. Therefore, the coefficient of friction on the contact surface between the friction member 17 and the flange 61 can be arbitrarily changed to thereby control the frictional force acting when the roll 6 on the ink film payout side is rotated.

Title: Gas insulation vessel
Inventor: HANEUMA HIROYUKI
IPC: H02G5/06
Filed: 1988-10-31
Abstract: PURPOSE:To inhibit the flying of metallic particles even when the field strength of the internal surface of a metallic box body is high by forming a first dielectric coating layer on the internal surface of the metallic box body and a second dielectric coating layer fast stuck onto the first dielectric coating layer in a gas insulation vessel, into which a gas insulation switching device, etc., are housed. CONSTITUTION:First and second dielectric coating layers 12 and 11 are shaped onto the whole internal surface of a metallic box body 1. When the dielectric of a high resistivity material is used as the second dielectric coating layer 11, charges induced while interposing the second layer 11 from the metallic box body 1 are not generated, and the charging of metallic particles 10 is inhibited. When a low dielectric material is employed, the electric fields of the contacting sections of the metallic particles 10 and the second layer 11 and sections near the contacting sections are weakened, thus suppressing charging. Accordingly, the metallic particles are not attached onto an insulating spacer, thus preventing the deterioration of breakdown strength properties.

IPC: G11B5/127
Filed: 1985-12-11
Abstract: PURPOSE:To easily produce high-density nonmagnetic ceramics having alpha>=130X10<-7>% deg.C coefft. of thermal expansion by incorporating NiO, MgO, TiO2, and MnO therein. CONSTITUTION:This ceramics contains 100pts.wt. essential component consisting of 10-70mol% MgO, 20-80mol% NiO, 1-5mol% TiO2, and 5-20mol% MnO. The content of NiO is obtd. at >=20mol% in order to obtain alpha>=130X10<-7>% deg.C. However, sintering is extremely difficult and the ceramics having high porosity is obtd. at 1,400 deg.C sintering temp. if the component ratio of MgO is >=60mol%. The hardness is low and the ceramics having high reliability in the wear charac teristic is not obtainable if the component ratio of NiO is >=70mol%. Magnetic permeability exhibits the value over 2 and such value is inadequate as the nonmagnetic ceramics if the component of NiO exceeds 80mol%. These problems can be improved by simultaneously adding TiO2 and MnO to the ceramics. More specifically, the hardness is improved by compounding TiO2 therewith and the porosity is improved by compounding MnO having the effect of acceler ating the sintering therewith.
