Title: Power generator using superconductor
Inventor: KUBOTA HIROSHI
IPC: H02N11/00
Filed: 1988-10-29
Abstract: PURPOSE:To obtain an electric generator which is extremely high in efficiency, low in manufacturing cost, capable of generating a large current, simple in structure, trouble-free, and adapted for mass-production by a method wherein the generator is provided with a device which automatically switches a superconductor from a normal conductive state to a superconductive state or vice versa. CONSTITUTION:When a superconductor 2 is irradiated with heat and light such as rays of the sun 6 or the like to be warmed up to make its temperature higher than its critical temperature, the superconductor 2 is put out of a superconductive state and becomes a normal conductor, so that a permanent current dissipates. And, an induction current flows momentarily through a coil 3 close to the superconductor 2. And, when the radiated heat and light are shut off by the action of an optical shutter 4 and prevented from irradiating the superconductor 2, the superconductor 2 is cooled down by a coolant such as liquid nitrogen or the like to becomes supercondcutive, and then a permanent current flows through the superconductor 2 again owing to the magnetic filed of a nearby magnet 1. At this point, an induction current flows momentarily through the coil 3. Therefore, when an optical irradiation is intermittently performed through the optical shutter 4, a current flows through the coil 3. In this process, the optical shutter 4 serves as a switching device which switches the superconductor 2 from a superconductor to a normal conductor or vice versa.

IPC: H04N1/21
Filed: 1994-10-14
Abstract: PURPOSE: To output image information to a transfer destination by registering a facsimile equipment of other department or the like in advance and registering a transaction destination or the like as a destination of transfer so as to avoid reject of an incoming call due to deficiency in the memory residual capacity even on the occurrence of an error such as jam thereby receiving the image information from an important transaction destination or the like. CONSTITUTION: A user operates an operation display section 4 to register a facsimile equipment of another department in a company in advance as a transfer destination and to register a transaction destination or the like as a specific destination to be transferred and the registered content is stored in a system memory 3. When the residual capacity of the image memory 2 reaches a prescribed amount or below due to generation of jamming or the like, a plotter section 9 transfers the image information from the transaction destination registered to be a specific destination to the facsimile equipment of the other department registered as the transfer destination via a communication control section 10. The transferred image information is deleted from the image information memory 2 and when the memory residual capacity is recovered, the succeeding reception data are accepted.

Title: Motion detection circuit
Inventor: AIBA HIDEKI
IPC: H04N19/80
Filed: 1994-10-13
Abstract: PURPOSE: To provide a motion detection circuit capable of making accurate motion detection while minimizing cost increase. CONSTITUTION: A difference between an input signal S0 and a signal S4 obtained by delaying the signal S0 by two frames is obtained and a 2-frame detection signal Δ04 is obtained.

Title: Placing table for close-up photographing
Inventor: KANAI MASAHARU
IPC: G03B17/56
Filed: 1993-11-02
Abstract: PURPOSE:To provide a placing table for close-up photographing which prevents photographing in a state where a stroboscope comes out, and which can be applied to the close-up of a subject whose specific character becomes clear when the subject is illuminated with light from below. CONSTITUTION:Non-glare processing is performed to the subject placing surface 62 of the placing table 60 for close-up photographing 60, so that strobe light from above is scattered on the placing surface 62. Since the strobe light is not regularly reflected on the placing surface 62 even when the close-up is executed in a state where the stroboscope is used, the stroboscope does not come out. After the strobe light transmitted through the placing surface 62 passes a space 66 under the placing surface 62, it is reflected by a mat 56 and illuminates the subject from below. Thus, this placing table 60 is applied to the close-up of the subject such as emerald 70 whose specific character becomes clear when it is illuminated with light from below.

Title: Method for dehumidifying gas containing carbon dioxide
Inventor: TSUKAMOTO TOSHIAKI
IPC: B01D53/04
Filed: 1994-11-09
Abstract: PURPOSE: To always maintain the high adsorption capacity of a dehumidification agent by setting a dew point at the outlet of a dehumidification tower low by installing a group of cooling pipes in an adsorption tower for dehumidification and removing the heat of adsorption generated during dehumidification. CONSTITUTION: Cooling pipes 2 for passing cooling water are installed in a dehumidification tower 1 filled with a dehumidification agent 12, and cooling water is introduced from a line 3 and discharged from a line 4. Raw gas containing water is supplied from a line 10, the flow of the gas is straightened in a ceramic ball layer 11 in the lower part of the dehumidification tower 1, the water is removed by the dehumidification agent 12, and then gas is released as dry gas from a line 13. Since a water absorbent generates the heat of adsorption at the adsorption of water, the heat is removed in sequence from the lower part of an adsorption tower by installing a group of cooling pipes. In this way, the adsorption capacity of the dehumidification agent can always be kept high.

Title: Logic circuit
Inventor: NANBU HIROAKI
IPC: G06F7/50
Filed: 1990-10-17
Abstract: PURPOSE:To shorten a logic cycle time of a logic circuit by adding the latch function to first and second logic circuits, and operating first and second logic circuit blocks by a pipe-line. CONSTITUTION:For example, four full adders are used to constitute a 4-bit adder which adds 4-bit binaries X4 to X1 and Y4 to Y1. In this case, each full adder FA cannot calculate a sum S1 and a carry C1 to upper bits unless a carry Ci-1 from lower bits is determined. The latch function is added to full adders FA(1) to FA(4), and all full adders FA(1) to FA(4) are operated with clock signals CLK1 to CLK4 by pipeline. Thus, the driving cycle of the 4-bit adder is approximately equalized to a delay time tFA of each full adder.

Title: Positioning method for magnetic head
Inventor: IDE TAKAHIRO
IPC: G11B21/10
Filed: 1985-12-09
Abstract: PURPOSE:To attain the positioning of a magnetic head in small correcting frequencies and to shorten the access time by reading and storing previously the eccentric amount of a floppy disk and positioning the magnetic head in accordance with the eccentricity of the floppy disk when the magnetic head is shifted to a desired track. CONSTITUTION:Servo information is previously recorded on each sector of each track of a medium 1 and the eccentric amounts of one or several tracks are read and stored when the medium 1 is changed or when a fixed period of time passed with no change of the medium 1. A microprocessing unit 10 storing the position shift information always monitors the time sent from an index signal when the unit 10 shifts a magnetic head 3 to a desired track. Then the unit 10 decides the time point when the head 3 is settled from the index signal after the head 3 is shifted and then calculates the present sector position from said time point. Thus an actuator 4 is started based on the profile of the eccentric amount of the medium 1 that is read out previously.

Abstract: PROBLEM TO BE SOLVED: To form an image in the same time requirement as in case of feeding paper from a paper feeding stage close to an image forming part even in case of feeding paper from a paper feeding stage positioned away from the image forming part. SOLUTION: An image forming device is provided with a control device 20 for performing the change control of the rotating speed of feed rollers 9A-9D in a plurality of paper feeding stages.
