Title: Solid-state image pickup device
Inventor: KIRIYAMA YOSHIYA
IPC: H04N5/335
Filed: 1990-06-28
Abstract: PURPOSE:To correct a dark current component uniformly by inputting charge equivalent to a dark current correction component to a shift register according to a 2nd signal based on a 1st signal obtained when a light receiving element is shielded against light. CONSTITUTION:Dispersion in a dark current component is detected by reading an information charge from a light receiving element 1 before the light receiving element 1 is irradiated with the light and a signal Yt correcting the dispersion in the dark current component is obtained by inverting a signal Xt obtained through the detection at an inverting amplifier 8 having a gain of -G. Then the electric charge quantity equivalent to the signal Yt is supplied from an input section 9 to an input terminal of a shift register 2 to store the charge to compensate the dispersion in the dark current component to each bit of the shift register 2 in advance. Thus, the dark current component is uniformly corrected.

Title: Printed matter
Inventor: KINOSHITA SATOSHI
IPC: B42D15/10
Filed: 1994-06-30
Abstract: PURPOSE:To provide a printed matter which can take effect of checking effectively to copy of an evil intention and is formed into a various pattern. CONSTITUTION:A pattern whose dissolution capacity levels by a copying machine are different from each other are used as a copy checking pattern to be formed on a printed matter, for example, a gradation is provided on distances between half-tone dots and lines or a thickness of parallel lines and a distance between the myriad lines of a screen tint. Therefore, since a copy checking pattern is copied into a different form by a dissolution level of the copying machine, discrimination that it is a copied matter can be performed easily. The copy checking pattern is printed by multi-color printing for which a plurality of colors are used, for example, rainbow printing allowing to express a mixed part 2b by mixing up a red 2a and blue 2c with each other or stuck- printing and a copy checking function can be displayed to the various copying machines whose optical properties are machine.

Title: Pulse combustion device
Inventor: HOSAKA MASATO
IPC: F23C15/00
Filed: 1984-08-18
Abstract: PURPOSE:To prevent the generation of beat of combustion noise and to decrease the generation of noise, by a method wherein plural pulse burners each having an exhaust cushion chamber are located in juxtaposition, and each exhaust cushion chamber is communicated with a synchronizing chamber. CONSTITUTION:Plural burners 1, 2, 3 and 4 are arranged in juxtaposition for combustion, a synchronizing chamber 11 is located to the central part of each exhaust cushion chamber so that the pressures of exhaust cushion chambers 9, 9', 10 and 10' are influenced on each other, and a communicating port 42 is bored in a partition 14 connected with each exhaust cushion chamber. This structure causes the pressure action of one exhaust cushion chamber 9 to be exerted on other exhaust cushion chambers 9', 10 and 10', and mutual action of a pressure is produced between the exhaust cushion chambers. Thus, since a pressure is changed in a direction in which the one frequency and phase coincide with the other frequency and phase within each of the burners 1, 2, 3 and 4, in relation to a pressure in each combustion chamber, the frequency and the phase of the one pressure coincides with those of the other pressure, timings of ignition also coincide with each other, the combustion chambers perform combustion in synchronise with each other, and this prevents the occurrence of beat phenomenon.

Title: Paper sheet separating device
Inventor: MIZUNO EIJI
IPC: B65H3/46
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To attain size reduction in a device by detecting the passing of a paper sheet, detecting the magnitude of a load from a change in a driving current of a stepping motor to drive a feed roller, and controlling the driving current of the stepping motor in a switching system according to the detected load. SOLUTION: When a paper sheet passing detecting sensor 8 detects the tip of a paper sheet 1, a load of a stepping motor 14 is detected by a microcomputer 10, and when the load is larger than a certain specific value, seperation is done once more. The fact that the paper sheet 1 passes through between a feed roller 5 and a gate roller 6 is detected by the paper sheet passing detecting sensor 8. When the paper sheet 1 does not pass through a separating part, a driving current of the stepping motor 14 is reduced, and when the driving current of the stepping motor is switched, heating and electric power consumption of a motor driving part 13 can be reduced. As a result, the driving current of the stepping motor can be controlled so that a wasteful electric current does not flow.

Filed: 1988-07-11
Abstract: PURPOSE:To obtain the title porous form suitable for separating agents or adsorbents by dissolving a silicon alkoxide partial condensate in a water- insoluble organic solvent, dripping the resultant solution into water to form a particulate gelled product which is then separated and calcined. CONSTITUTION:Firstly, a silicon alkoxide (e.g., tetraethyl silicate) is hydrolyzed to prepare a solution containing a silicon alkoxide partial condensate of the formula (n is 0-8; R is alkyl). Second, an organic solvent virtually incompatible with water (e.g., hexane) is added to this solution to dissolve said partial condensate of the formula in the organic solvent. Third, the resultant organic solution is dripped into water to form a particulate gelled product; which is then separated from the solution and calcined at 800-1200 deg.C, thus obtaining the objective spherical silica porous form. Having relatively large-sized pores, this porous form can be suitably used as e.g., a separating agent for biologically related substances.

Abstract: PURPOSE:To multiplex a sound signal to a picture signal, by displaying the existence of the sound signal by using the uppermost bit, multiplexing the sound signal to the picture signal, and on the receiving side, discriminating the code indicating the existence of the sound signal to separate the sound signal. CONSTITUTION:On the transmitting side, an analog sound signal (b) applied to an input terminal 2 is converted into a digital signal (h) by an A/D converter 4 and the digital signal (h) is applied to a parallel/series converting circuit 9. The circuit 9 applies a signal (k) obtained by converting the digital sound signal into a series signal to a multiplexing circuit 11, which inverts the uppermost bit of the shortest code and adds the sound signal to the shortest code to multiplex the signals. On the receiving side, a multiplexed signal (n) applied to an input terminal 21 is added to a variable length decoding circuit 22 and a detecting circuit 23 and the circuit 23 detects a signal ''0111'' indicating the existence of the sound signal from the multiplexed signal (n). A separating circuit 24 can separate the sound signal following the signal ''0111'' obtained before decoding. Consequently, the sound signal can be multiplexed to the picture signal without constituting a frame.
