Abstract: PURPOSE:To enhance a durability and an efficiency by superposing an AC voltage synchronized with the drain current of an MOS field effect transistor on a DC voltage, and applying it to the gate of the transistor to stabilize an oscillation.

SOLUTION: An article (A) having a surface having an angle of contact with water of 150 deg. or larger (ultra-water-repellent) is irradiated with light, whereupon the angle of contact with water is decreased to below 150 deg. (non-ultra-water repellent). Thus, the water repellency is regulated. A suspension comprising an irregularity-forming fine powder, a water-repellent fluoro compound, a resin, etc., is applied to the surface of an article and cured to make an ultra-water-repellent surface. Next, a layer (B) of a photosensitive material comprising e.g. a photochromic compound is formed on component A. Components A and B form a partially non-ultra-water-repellent surface (pattern latent image) by light irradiation. It is also possible to simultaneously form A and B on the surface of an article by applying a mixture of materials A and B to the surface.  The fluoro compound in component A is desirably a compound represented by formula I (wherein Rf is a group represented by formula II; and R is a structure represented by formula III or the like).

That is, the positive type photoresist 4 which is easily controlled for the thickness after the developing by the exposure amount is employed, and the lower part 12 is merely exposed as designated by 7 so that the residual resist film thickness 43 on the lower part 12 of the unit becomes equal to that 41 of the resist on the high part 11 of the nonexposure unit by the edge of the film of the resist 4 due to the exposure. Thus, the surface of an insulating film 5 on both the parts 11 and 12 can be flattened under the same etching-back conditions.

Abstract: PROBLEM TO BE SOLVED: To suppress the consumption of a battery by inputting a pulse width modulation signal to an output transistor from a control circuit and cutting the power supply to a motor from the battery in an output transistor when the pulse width modulation signal is off. SOLUTION: When a pedal crank is worked, a pedaling torque detecting mechanism 81 detects the pedaling torque at that time, and outputs a pedaling torque signal FL.

Abstract: PURPOSE:To improve the discharging ratio of coins by rotating a coin feeding disk at high speed at a tilted position within a hopper, picking coins upward one by one with a coin feeding piece from the inside of the hopper and moving the picked-up coins along a circumferential wall by means of a centrifugal force.

To the contrary, at the diametrical opposite position to the coin outtake part, the projection amounts within the hopper 4 are made maximum, respectively, to permit the coins to be effectively picked up and so the stirring effect of the coins can be improved. Thus, a coin transmission belt part 28a is straightly expanded toward the coin outtake port on a plane including the surface of the coin feeding disk 2.

Filed: 1992-10-08
Abstract: PURPOSE:To obtain a carbonic acid ester from an easily handleable raw material under a relatively mild reaction condition by an absolutely new process comprising the catalytic reaction of methanol, a formic acid ester or a formic acid ester and an alcohol in the presence of a solid catalyst. CONSTITUTION:A carbonic acid ester is produced by the catalytic reaction of methanol, a formic acid ester or a formic acid ester and alcohol according to the reaction formulas (1), (2) and (3) in the presence of a solid catalyst (especially preferably a catalyst containing copper and a chromium oxide). The process is easily operable since it does not necessitate a toxic or combustible particular gas as a raw material. The use of a solid catalyst facilitates the separation of the catalyst from the reaction mixture. It is not necessary to use a particular material for the reactor. The process is advantageous because the reaction proceeds under relatively mild condition.
