Filed: 1991-10-02
Abstract: PURPOSE:To simply obtain the subject compound useful as a minor tranquilizer acting on central nervous systems or as a muscle relaxant in a high yield by reducing a quinazolinone derivative with hydrosulfite. CONSTITUTION:2-Fluoromethyl-3-(2-methylphenyl)-6-nitro-4(3H)-quinazoli none of formula I is reacted with hydrosulfite in a solvent (e.g. methylene chloride) at 5-100 deg.C for 30min to 5hr to obtain 6-amino-2-fluoromethyl-3-(2- methylphenyl)-4(3H)-quinazolinone of formula II. The hydrosulfite is used in an amount of 1-6 times moles that of the compound of formula I. The nitro group of the compound of formula I can selectively be reduced, while the fluorine of its fluoromethyl group is not removed. Since a multi-valent metal is not used, the method does not cause any trouble relating to the industrial waste treatment of the metal.

Title: Heat pump type air conditioner
Inventor: GOTO HIROKI
IPC: F25B13/00
Filed: 1988-11-10
Abstract: PURPOSE:To improve responsiveness to the variation of an air conditioning load by a method wherein the title device is so constituted that a four-way valve is reversed by a four-way valve reversal control timer, within the time-up of a compressor restart delay timer, and a high pressure and a low pressure are rapidly balanced. CONSTITUTION:When an air conditioner control input circuit 1 receives an input of the stopping of the operation of a compressor 10, it produces an output to a microcomputer 2. Thereupon, the microcomputer 2 opens a relay contact 8 which supplies a power to the compressor 10, through a relay control circuit 6, and allows both a compressor restart delay time 3 and a four-way valve reversal control timer 4 in a timer circuit 5 to start the counting. Then, the four-way valve reversal control timer 4 terminates first, and the timer circuit 5 outputs this termination. Upon receipt of this output, the microcomputer 2 produces an output to the relay control circuit 6 so that a relay contact 9 is switched so as to reverse a four-way valve 11. As a result, the four-way valve 11 is reversed and, at the same time, a high pressure side and a low pressure side in a refrigerating cycle communicate to each other, whereby the unbalance between a high pressure and a low pressure at the stopping of the operation of the compressor 10 can be balanced.

Filed: 1993-11-15
Abstract: PURPOSE:To provide a means for realizing the phase shift reticle having high accuracy by the simple method. CONSTITUTION:A phase shifter film 2 and a light shielding film are formed on a transparent substrate 1. Light shielding film patterns 31, 32 having openings 30 of a first width are formed by patterning the light shielding film. A photosensitive film having a negative characteristic is formed over the entire surface thereof and is irradiated with UV rays from the rear surface of the openings 30. The photosensitive film having the negative characteristic is then developed to form the photosensitive film 5, of the first width. The photosensitive film 51 of the first width is subjected to an ashing treatment, by which the photosensitive film 52 of the second width narrower than the first width is formed. The phase shifter film 2 is etched with the photosensitive film 52 of the second width and the light shielding film patterns 31, 32 as a mask and the phase shifters are formed by the phase shifter patterns 22 right under the photosensitive film 52 of the second width. The formation of the photosensitive film 52 of the second width by excessively developing the photosensitive film 5 is possible as well.

Filed: 1993-11-15
Abstract: PURPOSE:To prevent a rush current at the time of power source ON by providing a capacitor whose one terminal is connected between the input terminal of a switch part connected between a power source and a load and the other terminal is connected to the other terminal of the power source. CONSTITUTION:When an ON/OFF signal is inputted to a control part 4, based on a control signal S1 from a control part 4, current is allowed to flow into a ground GND through the base and emitter of a transistor Q2 at a power source ON/OFF part 2 to turn on the transistor Q2, and allowed to flow into a collector of a transistor Q3 through the base from the emitter of a transistor Q1 to turn on the transistor Q1. Thus, a charging current is allowed to flow from a battery B1 of a power supply part 1 to a capacitor C2, and electric charges charged in a capacitor C1 are charged through the transistor Q1 to the capacitor C2. Therefore, the rush current from the battery B1 can be reduced by complementing the rush current flowing from the battery B1 of the power source supply part 1 at the time of current ON with the electric charges charged at the capacitor C1.

Abstract: PROBLEM TO BE SOLVED: To always obtain an excellent image by providing a scraping member scraping a foreign matter on an image carrier, allowing an electrifying member to stick developer onto the scraped foreign matter, and recovering it via the image carrier. SOLUTION: When a photoreceptor 21 is rotated (in a direction shown by an arrow C), the foreign matter adhering to the photoreceptor 21, such as the foreign matter and residual toner, is successively scraped by the blade 62 of a scraper member 60. The foreign matter and the residual toner pass through a hole 61a made on an elastic member 61 and are stirred and also electrified by the rotation of an electrifying roller 23a (in a direction shown by an arrow B), whereby the residual toner is attracted to the foreign matter. The foreign matter stuck with the residual toner is carried to a downstream side by the rotation of the roller 23a. By attracting the residual toner stuck onto the foreign matter to the electrified surface of the photoreceptor 21, the foreign matter is laminated on the photoreceptor 21.  Thereafter, the residual toner and the foreign matter are carried and recovered in a developing device by the rotation of the photoreceptor 21.
