Title: Solid-state image pickup device
Inventor: KOYAMA HIDETSUGU
IPC: H04N5/353
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To suppress increase in power consumption caused by an electronic shutter operation by reducing the pulse amplitude of a shutter pulse train impressed to a board rather than the pulse amplitude of a rear side pulse train including the final pulse. SOLUTION: The amplitudes of a final reference pulse ϕS1 and a front side reference pulse train ϕS2 are respectively amplified by 1st and 2nd amplitude conversion circuits 103a and 103b, to which different power supply potentials VS1 and VS2 are supplied, and they become a final shutter pulse ϕS1 ' and a front side shutter pulse train ϕS2 '. These pulses ϕS1 ' and ϕS2 ' are synthesized by a pulse train synthesizer 104 and are turned to a synthetic shutter pulse train ϕS' and supplied through a capacitor 204 to the board of a CCD part 201. Thus, most of pulses in the shutter pulse train ϕS' inside one field can be provided with an amplitude level VS2 lower than an amplitude level VS1 of the final shutter pulse ϕS1 '. Then, power consumption is reduced by making the pulse used for operating an electronic shutter into low voltage.

Filed: 1985-12-14
Abstract: PURPOSE:To obtain a developed image which has small edge effect and sufficient solid-black density by providing a means which produces an alternating electric field for transferring toner particles from a layer of toner particles formed on the surface of a developer carrier member to an electrostatic latent image carrier at a development part. CONSTITUTION:A power source 34 applies a voltage to between a photosensitive drum 1 and a sleeve 22 to produce the alternating electric field and toner particles are transferred from a developer on the sleeve 22 to the toner photosensitive drum 1. The development part transfers toner from the surface of the sleeve 22 and surfaces of magnetic particles onto the latent image with the alternating electric field applied to between the photosensitive drum 1 and sleeve 22 to develop the latent image. Toner particles which are not consumed for the development are recovered through the subsequent rotation of the sleeve 22 and applied onto the sleeve 22 again repeatedly by circulation. A repulsive magnetic field is established at the development part, so magnetic particles are agitated and then only toner having sufficient triboelectricity is used for the development, so that sufficient solid-black density is obtained during solid- black development.

Filed: 1985-12-14
Abstract: PURPOSE:To improve the heat exchange efficiency of an air conditioner by a method wherein ice is formed in the shape of ice slurry, which is allowed to be transported through piping, and the ice slurry is conserved as it is in a heat accumulator so as to store cold heat. CONSTITUTION:A cooling means 5 or a means to cool brine fed to an air conditioner 3 by stored cold heat consists of a take-out passage 17 equipped with a pump 17a, which takes ice slurry out of a heat accumulator 5 in order to pour the slurry into a brine feeding passage 11. When cooling is unnecessary or during the night and the like, a cold heat generator 1 is put into operation so as to manufacture the ice slurry at an ice plant 4. The manufactured ice slurry is conserved in the heat accumulator 5 so as to store cold heat. When cooling is required, the brine is cooled at a cooling device 2 by operating the cold heat generator 1 and at the same time by the stored cold heat. Because some part of cooling is supplemented by the stored cold heat, the load on the cold heat generator 1 is reduced and consequently the miniaturization of the cold heat generator 1 is contrived.

Filed: 1985-12-17
Abstract: PURPOSE:To enable the titled method to execute the titled setting highly precisely without melt loss in the circumference, by a method wherein a heating nut is pressed in an insert hole of a molded material by making use of a specific holding member and synthetic resin on the circumference is softened by a potential quantity of heat of the heating nut. CONSTITUTION:A holding member 3 or 3a in a rotary shaft 21 of a jig 2 is inserted to a female threaded hole 1a of a heated nut 1 and pressed in a insert hole 4a of a synthetic resin molded member 4. As a spiral knurling tool 14 turns a rotary shaft 2 and the nut 1 and rotary shaft 21 are turned unitarily, the nut 1 comes into a state wherein the nut 1 is screwed in to the molded member 4 by the knurling tool 14.

Title: Image compression data expander
Inventor: HASEGAWA MAKOTO
IPC: H04N5/937
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To realize the system in which a succeeding image from an upper part of an image is displayed sequentially at a speed in response to the line data rate by using a microcomputer to measure a time between an SOI signal representing a head added to a compression image data signal and an EOI signal representing an end. SOLUTION: Compressed data are stored in a memory as one compression signal with an SOI signal representing a start and an EOI signal representing an end. When a data rate of a line is low, the EOI and SOI signals detected by an EOI/SOI detection circuit 2 are read by a control circuit 7 under the control of micro software, a time between the EOI and SOI signals is measured by the control circuit 7 and image data after expansion are transferred from a raster/block conversion LSI 4 to a frame memory 5 at a speed equivalent to the time interval. Since a current image pattern is replaced sequentially from an upper part into a succeeding pattern, the operating state is confirmed even when the speed is slow.
