Title: Cleaning method of photomask
Inventor: NARAOKA KIYOTAKE
IPC: G03F1/82
Filed: 1982-08-02
Abstract: PURPOSE:To clean a photomask to be used as an original plate in photolithography without damaging the metallic film for light shielding, by dipping the photomask in a bath of a sulfuric acid or the like while applying a voltage between the photomask and the counter electrode thereof. CONSTITUTION:A photomask 8 formed with a figured patternlike chromium film 12 on a glass substrate 10 provided with a light transmittable conductive film 11 is subjected to a cleaning treatment. More specifically, the above-mentioned photomask 8 (a symbol 9 is a clip) and a platinum plate 14 are dipped perpendicularly in the sulfuric acid 2 in a cleaning tank 1. The acid 2 is heated to about 90-120 deg.C with a heater 3 and foam 15 of ozone-contg. air is ejected through a blow pipe 5 and a blow-out port 6 into the acid 2 to generate a Caro's acid. On the other hand, about 1.5-2.5V DC voltage is applied between the plate 14 (cathode) and a chromium film 12 (anode) by a power source 13. Therefore, the film 12 is immobilized by the oxide film formed on the surface thereof and since it is insoluble, only the foreign matter such as photoresist sticking on the mask 8 is dissolved away in the Caro's acid.

Title: Mechanism and method for measuring steaming time for green tea manufacture
Inventor: UCHIDA TAIZAN
IPC: A23F3/06
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a mechanism and a method for measuring a steaming time for green tea manufacture by more accurately measuring the weight of tea leaves passing through steaming barrels in calculating a time required for the tea leaves passing through the steaming barrels of a green tea manufacturing machine. SOLUTION: In a structure and a method for calculating the transit time of tea leaves through steaming barrels by dividing the weight of tea leaves passing through the steaming barrels 5 of a green tea manufacturing machine 1 by a feed rate per unit time of raw tea leaves, when the weight of tea leaves is measured, stationary frames 7 are not measured, movable frames 6 directly supporting the steaming barrels 5 are apparently lightened by using balance levers having a weight, etc., to measure the weight of tea leaves in the steaming barrels 5. The weight of tea leaves is measured together with the steaming barrels 5. Since the stationary frames 7 or the stationary frames 7 and the movable frames 6 are not measured and only the weight of tea leaves is measured, the steaming time is measured in an excellent accuracy. Small-sized and light-weight members for keeping balance are used.

Filed: 1988-05-31
Abstract: PURPOSE:To enable a smooth speed change operation in the title speed change structure by forcibly delaying the timing of a lock-up operation when the lock-up operation is performed together with the 'in' operation of a hydraulic clutch. CONSTITUTION:When a forward/backward changeover switch 21 is switched into the forward side F so as to turn in the hydraulic clutch 15a on the forward side, a lock-up switch is pushed, so as to generate an operational signal after an elapse of a set time (t) from the timing (a2) of the push operation, thereby obtaining the lock-up state of a torque converter T. Thus, even if the turning in operation of the hydraulic clutch 15a is abraptly performed, there occurs slippage in the torque convertor, so that it is possible to soften the shock so as to obtain a smooth speed change operation.

Title: Data writing and erasing method for semiconductor memory device
Inventor: ONO TAKASHI
IPC: G11C17/00
Filed: 1989-05-29
Abstract: PURPOSE:To increase reloadable time without increasing the number of manufacture processes or the size of a cell by separating a current path for writing and erasing into a source area and a drain area. CONSTITUTION:A source area 23 and a drain area 22, in which the concentration of impurity is almost equal, are formed in a substrate and a floating gate 25 and a control gate 27 are formed through insulating films 24 and 26 on the substrate. When data are written, an electric charge is injected to the floating gate 27 near the drain area 22 and the data are erased, the electric charge is neutralized in the floating gate 27 near the source area 23. Then, each current path is separated for the time of writing and the time of erasing and the insulating films 24 and 26 under the floating gate 27 are suppressed to be degraded. Thus, since the concentration of the impurity is almost equal in the source area 23 and drain area 22, the number of the manufacture processes can be decreased and the size of the cell can be reduced. Then, the reloadable time can be increased.
