Title: Air cell
Inventor: YOSHIDA KAZUMASA
IPC: H01M4/90
Filed: 1981-08-28
Abstract: PURPOSE:To obtain an air cell which has a high voltage and a large capacity by using an electrolyte consisting of an aqueous ammonium chloride solution. CONSTITUTION:A positive lid 1 also serving as a positive terminal is in electrical contact with a porous carbonic bar 10, and has an air supplying hole 2. An air electrode 3, which is in contact with a lyophilic barrier 4, consists of cobalt phthalocyanine, active carbon and a water-repellent fluorine resin. A pasty electrolyte 5 prepared by kneading starch into 20wt% ammonium chloride solution used as an electrolyte is in contact with a negative electrode 6 made of a zinc can. In addition, a negative can 7 is sealed, with a gasket 8 interposed between the positive lid 1 and the negative can 7, by curving the opening of the lid 1 so as to seal the battery. A sealing member 9, which is made of a polyvinylchloride sheet and seals the air supply hole 2, is a pressure-sensitive tacky agent. Since metal phthalocyanine is combined with active carbon in this invention, the electrolyte 5 has a high reducing acitivity. Consequently, both the operational discharge voltage and the discharge capacity of the battery are increased.

Filed: 1977-11-10
Abstract: PURPOSE:To make it possible to obtain a fixed-period relaxation oscillation to drive a LED normally even in case of the fluctuation of the power supply voltage and prevent power consumption from being wasted. CONSTITUTION:This circuit is constituted by a time constant circuit, where capacitor C is connected to DC power source Vc through constant current circuit CI, and a discharge circuit where a series circuit of swithihg element S, which is conductive at a prescribed potential, LED D and coil L is connected. Here, the current becomes constant against the voltage fluctuation of DC power source Vc because of constant current circuit CI; and when capacitor C is charged by the constant current to make switching element S conductive, the current is flown through the discharge circuit. By repeating this operation, a fixed-period relaxation oscillation is performed, and the LED is lit normally. Then, current IL flowing to LED D has a phase delayed more than current IR for no coil L interposed, and the light emission time of LED D is delayed by this phase delay and can accord to the response characteristic of the photo detector.

Title: Paper feeding device
Inventor: WATANABE TSUTOMU
IPC: B65H9/00
Filed: 1982-08-03
Abstract: PURPOSE:To reduce intervals of fed transfer papers to use effectively a photosensitive face, by moving a transfer paper in a speed higher than the peripheral speed of a photoreceptor when the leading end of the transfer paper is between the photoreceptor and resist rolls. CONSTITUTION:When a transfer paper 4 held between resist rolls 6 is fed synchronously with a toner image of a photoreceptor 1, the transfer paper speed is raised to a speed V2 higher than a peripheral speed V0 of the photoreceptor 1 and is returned to the speed V0. The similar operation is performed for the next transfer paper 4, and an interval l1 between the preceding transfer paper 4 and the succeeding transfer paper 4 is determined by a time t1 required for raising the transfer paper speed to the speed V2 from the start of the rotation of rollers 6, a time t2 for which the speed V2 is held, and a time t3 required for lowering the transfer paper speed from the speed V2 to the speed V0. Consequently, these times are adjusted to make it possible to set the interval l1 to a very small value or 0. Thus, the interval l1 is reduced in accordance with the interval of toner images on the photoreceptor 1 to use effectively the photosensitive face.

Abstract: PURPOSE:To decrease black and white streaks and unevenness in density occurring around a place where areas of images recorded by each one of horizontal scannings adjoin each other by a method wherein a recording head is moved in the vertical scanning mode so that the second image area is partially placed on top of the first image area. CONSTITUTION:The first image area is recorded by making an ink jet recording head operated in the horizontal scanning mode. In proceeding to the recording of the second image area by making the recording head move in the vertical scanning mode after completion of the recording of the first image area, the vertical scanning is made so that ejection ports No.1-No.3 are operated in overlapping the first image area. Pixels in the area covered with the above- mentioned overlapping are applied with two times of ink jetting; namely one ink jetting per each of two scannings. The density of the pixels in the said area is controlled by total amount of ink droplets ejected thereto. Thereby black and white streaks and un-evenness in the density occurring around the place where the areas of images recorded by each of the scannings adjoin each other are considerably reduced.
