Filed: 1989-01-19
Abstract: PURPOSE:To enhance preservation stability, particularly resistance to chemicals, water and heat by providing a thermal color forming layer comprising a specified leuco dye, 4,4'-dihydroxybenzophenone for developing the leuco dye into a color when being heated and a binder soluble in an aliphatic or aromatic hydrocarbon solvent as main constituents, on a base. CONSTITUTION:A thermal color forming layer comprising a leuco dye of the formula, 4,4'-dihydroxybenzophenone for developing the leuco dye into a color when being heated and a binder soluble in an aliphatic or aromatic hydrocarbon solvent as main constituents is provided on a base. As a color developer, 4,4'- dihydroxybenzophenone is preferably used singly, but one or more color developers may be used joinly as far as the use thereof does not impair resistance to chemicals, water and heat. As the binder, a resin soluble in an aliphatic or aromatic hydrocarbon solvent, for example, an acrylic resin is used. The mixing ratio of the leuco dye to the color developer is preferably in the range of from 1:1 to 1:3. The proportion of the binder is 20-60% based on the total amount of the thermal color forming layer.

IPC: G11B31/00
Filed: 1994-01-28
Abstract: PURPOSE:To perform magnetic recording well by adjusting the recording density or recording signal standardly set for magnetically recording binary data in the case of detecting a condition where a film feeding speed is easy to minutely vary. CONSTITUTION:A microcomputer 4 judges whether or not there is a high possibility to cause the jitter before the magnetic recording is started. The microcomputer 4 sets write data in the case an exposure completion signal is inputted, then sets the operation condition of a write circuit 31 in order to perform the magnetic recording with standard recording density and with a standard recording signal. When the film feeding speed is detected to be equal to or below a reference speed, the microcomputer 4 inputs a correction signal to the circuit 31, and the circuit 31 changes the recording density and the recording signal. When the film feeding speed is equal to or below the reference speed, a correction timing pulse can be directly supplied to the circuit 31 from the microcomputer 4.

Title: Ion etching method
Inventor: OKANO HARUO
IPC: H01L21/3065
Filed: 1979-01-31
Abstract: PURPOSE: To etch selectively one of two different materials, by producing plasma in a gas contg. halogen element, and by casuing ions in the plasma to collide against a gas contg. no halogen element in an isolated sample chamber.  
     CONSTITUTION: A gas contg. a halogen element, e.g., C 2 F 6  gas, is introduced into a discharging chamber composed of a cover 12 for producing press. difference and an ion source. The gas is ionized by discharge and is released as an ion beam 7, which is irradiated on the objects 14 to be etched placed in a sample chamber 19, the objects 14 having materials different from each other. Introduction of a gas contg. no halogen element, e.g., H or O atom through an inlet 17 to the chamber 19 causes selective etching of the object to be etched. That is, change in the ratio of addn. of H 2  or O 2  to the indroduced gas, e.g., C 2 H 6 , causes to adjust the etching speed of the objects to be etched. Consequently two materials different from each other are etched selectively.

Abstract: PURPOSE: To open flasks automatically only by shifting a moving truck left and right by a mechanism wherein a lever for pulling, which hangs the pawl portions of filter plates and can pass in the one direction, is mounted to the moving truck.  
     CONSTITUTION: When a truck 1 left locomotes, a pulling lever 17 energized at an upper fixed location by means of a spring 14 and a stopper 9 passes through a lower side of a pawl portion 24 of a filter plate because its nose has an inclined portion 22, rises to the original position after it passes through the lower side, and is caught by the pawl portion 24. A stopper 26 of a space adjusting stop lever 18 energized at an upper fixed location by means of a spring 15 and the stopper 9 collides with the pawl portion 24, and the truck hangs a press flask corresponding to one flask and suspends. The truck 1 right moves and opens the flask, collides with a filter plate, whose flask is previously opened, and stops. And the truck left starts movement again, but the space adjusting stop lever 18 passes under the pawl portion 24 of the filter plate, whose flask is opened, because the lever 18 is pushed down by means of the pawl portion 24 of the filter plate, whose flask is before opened, at that time. The said flask opening operation is repeated.

Filed: 1981-01-27
Abstract: PURPOSE: To improve metallic gloss and wettability of pure tin solder by electrodepositing tin on a steel strip then melting the tin in a high frequency induction furnace, and water-cooling the same quickly thereby reducing an iron-tin alloy layer.  
     CONSTITUTION: A tin electroplated steel plate made by electrodepositing tin on a steel strip is heated to above the m.p. of tin by using a high frequency induction heating furnace or a high frequency induction heating furnace making combination use of the resistance heating to heat the steel plate with the Joule heat generated by direct conduction of electricity as a heat source. By these heating furnaces, the surface of the steel plate is quickly heated to melt only the tin of the surface layer, thereby forming an iron-tin alloy layer and improving corrosion resistance and metallic gloss. Next, in order to limit the growth of the iron-tin alloy layer, the steel material is cooled to the m.p. or below with water within 0.3 second upon melting of the tin, whereby the pure solder wettability is improved.
