Title: Advanced '1' detecting circuit
Inventor: IWAMOTO HIROMI
IPC: G06F7/00
Filed: 1989-10-27
Abstract: PURPOSE:To detect the advance '1' at high speed in a small area by providing a pass gate for carry signals to only a transmission control element of each 1-bit '1' detecting circuit and securing the connection between the 1st and 2nd units via an inverter. CONSTITUTION:A positive logic 1-bit '1' detecting circuit 10 and a negative logic 1-bit '1' detecting circuit 11 are prepared in two pairs respectively. Then the circuits 10 and 11 are connected to each other via an inverter. Thus the carry signal COUT received from a carry signal output terminal 16 of the circuit 10 is inverted by the inverter and sent to an inverted carry signal input terminal 22 of the circuit 11 of the next stage. In the same way, the inverted carry signal received from an inverted carry output side output terminal 24 of the circuit 11 is inverted and sent to a carry signal input terminal 13 of the circuit 10 of the nest stage. Meanwhile the carry and inverted carry signals passes through both circuits 10 and 11 pass through only a transmission gate 15. Thus the number of stages of gate circuit can be decreased. Furthermore the driving ability is maximized since the power source is supplied via the inverter. Then the carry transmitting speed is increased.

Title: Device for reproducing character and image
Inventor: AOKI SHIGERU
IPC: H04N1/405
Filed: 1984-12-25
Abstract: PURPOSE:To prevent ruggedness in edge parts of lines by integrating density information and outputting a dot each time when the integral result exceeds a threshold and comparing information corresponding to the output bit with the second threshold to discriminate the output of the dot. CONSTITUTION:Image information SA is converted to digital picture information SP by an A/D converter 5 and is inputted to an integrating circuit 1. The circuit 12 integrates information SP successively, and an integral result S1 is outputted to a comparator 2. The value S1 is compared with a threshold ThA by the comparator 2, and an output signal is outputted to the FF3 when the former is larger than the latter. The FF3 outputs a pule as a dot S0 on a basis of this output signal. Meanwhile, information SP is supplied to a comparator 4 also. Information SP is compared with a threshold ThB by the comparator 4; and if SP<ThB, it is judged that picutre elements having the density exist in the background part, and a reset signal is outputted to the FF3 synchronously with the signal passing the circuit 1. While the reset signal is applied, the FF3 inhibits the generation of the dot S0.

Title: Image recorder
Inventor: HORAGUCHI YOICHI
IPC: G03B27/32
Filed: 1989-10-27
Abstract: PURPOSE:To improve image quality by attaching a slide and a Fresnel lens so that they can relatively move and a photosensitive sheet travels at the speed in response to the relative movement and providing a slit in an optical path from a light source to an exposure surface. CONSTITUTION:The subject recorder is constituted in such a way that the slide 9 and the Fresnel lens 11 are attached so that they can relatively move and the photosensitive sheet 13a travels at the speed in response to the speed of the relative movement, and the slit 8 is provided in the optical path from the light source 5 to the exposure surface. When the image of the slide is exposed, the light source 5 is turned on and the slide 9 and Fresnel lens 11 are relatively moved. Therefore, the light transmitted from each image element of the slide 9 is used for slit-exposure while it crosses the surface of the Fresnel lens 11. Thus, an image exposed on the photosensitive sheet 13a does not obtain a concentric line of the Fresnel lens 11, so that the copied image of the slide 9 is sharper and image quality is improved.

Title: Engine-driven supercharging internal combustion engine
Inventor: NAKANO TAKESHI
IPC: F02B33/00
Filed: 1989-10-27
Abstract: PURPOSE:To obtain a smooth and desirable acceleration characteristic by closing a by-pass control valve with lag time corresponding to the engine speed at this time from clutch connection at the time of driving a supercharger. CONSTITUTION:A clutch 8 cuts off and connects the transmission of engine rotation to a mechanical supercharger 4 interposed at an intake passage 2. A by-pass control valve 7 closes a by-pass passage 6 formed in the intake passage 2 making a detour around the supercharger 4 at the time of driving the supercharger 4. Hereupon, a control unit 10 performs the control of closing the by-pass control valve 7 with lag time corresponding to the engine speed detected by an engine speed sensor 12 from the connection of the clutch 8 at the time of driving the supercharger 4. Accordingly, at the time of driving the supercharger 4, the clutch 8 is connected first of all so as to increase the rotation of the supercharger 4, and when the discharge of the supercharger 4 coincides with the natural intake quantity at that time, the by-pass control valve 7 can be closed. Intake air shortage and boost pressure rise delay can be thereby prevented, and an optimum acceleration characteristic can be secured.

IPC: H04M11/00
Filed: 1989-10-27
Abstract: PURPOSE:To reduce a time for a caller from being kept useless by measuring actually number of times of calls of a terminal equipment side adaptor responding to a tentative call from a management center and a call time length and revising a tentative call time and a holding time to the tentative call at the terminal equipment side adaptor based on the measurements. CONSTITUTION:In the case of making a tentative call from a center side 2, a tentative call time is varied in various ways to make a tentative call so as to measure whether or not a reply is made correctly from a terminal equipment 6 to the center 2. When the reply to the tentative call is not proper, the tentative call time is revised to change the holding time of the tentative call in the terminal side adaptor 4. Thus, number of times of correct reply at the terminal equipment 5 to the tentative call for plural number of times and the call time length are measured at that time and the optimum tentative call time and the holding time are decided based on the actual measurement. Thus, a wait time of a caller kept waiting useless calling from a general subscriber telephone set is reduced.

Title: Material for simultaneous removal of ion and microparticle
Inventor: SUGO TAKANOBU
IPC: D06M101/16
Filed: 1986-11-26
Abstract: PURPOSE:To produce a fibrous ion exchanger which can simultaneously remove dissolved ions and colloidal microparticles in a processing solution, by irradiating a fibrous base with an ionizing radiation and contacting it with a polymerizable monomer having an ion exchangeability. CONSTITUTION:A fibrous base (e.g., chopped twisted polyethylene yarn) is irradiated with an ionizing radiation (e.g., electron beams) and contacted with a polymerizable monomer (e.g., acrylic acid) having anion exchangeability or a polymerizable monomer having a functional group convertible into an ion exchange group to graft-polymerize the monomer. Alternatively the fibrous base and the polymerizable monomer are simultaneously irradiated with an ionizing radiation to graft-polymerize the monomer. Thus a fibrous ion exchanger can be obtained. Dissolved ions and colloidal microparticles in, e.g., water used in a nuclear plant can be simultaneously removed by using this ion exchanger, so that the resistance of flow of the processing solution is low and it can be purified in good efficiency.

Title: Sheet feeder and image forming device
Inventor: YUKIMACHI HIROSHI
IPC: B65H3/52
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent a retard roller from rotating in the overlapping conveyance preventing direction in starting a feed roler even if a frictional coefficient between both rollers is lowered so as to prevent a jam by applying overlappping conveyance preventing torque to the retard roller after a delay of a predetermined time from rotation starting timing of the feed roller. SOLUTION: When a motor is started for conveying a sheet S, a pickup roller 14 and a feed roller 15 are immediately started, while a projection 30b of a torque lilmiter 30 is not immediately brought into contact with a projection 16a of a retard roller 16 and no overlapping conveyance preventing torque is transmitted. Therefore, the retard roller 16 is always driven by the feed roller 15 so as to rotate in the conveying direction even if a surface frictional coefficient between the feed roller 15 and the retard roller 16 is low. Because the sheet S has been put between the feed rolelr 15 and the retard roller 16 already when overlapping conveyance preventing torque is transmitted to the retard roller 16, the sheet S can be surely fed in split of lowering of a frictional coefficient of the retard roller 16.
