Title: System for controlling feed of recording paper
Inventor: SHIRAKI MAKOTO
IPC: B41J2/325
Filed: 1984-11-01
Abstract: PURPOSE:To enable color recording with high image quality, by changing the movement of a thermal head and the rotary speed of a platen roller to a recording mode on the basis of the detection signal from a first sensor and determining the supply timing of a current to the thermal head on the basis of the detection signal from a second sensor. CONSTITUTION:When recording paper 1 reaches the position opposed to a first sensor 12, this state is detected by said sensor 12 to input the detection signal thereof to a controller 14. This controller 14 outputs a control signal to a head driving mechanism 6 in synchronous relation to the detection signal from the first sensor 12 or after a predetermined time to allow a thermal head 3 to move from a non-printing position C' to a printable position C and outputs a control signal for altering a speed to a roller driving mechanism 9 to change over the rotary speeds of a recording paper feed roller 7 and a platen roller 8 from a high speed to a low speed. When the recording paper 1 reaches the position opposed to a second sensor 13, this state is detected by said sensor 13 to input the detection signal to the controller 14 which, in turn, outputs a current supply signal to the thermal head 3 in synchronous relation to the detection signal from the second sensor 13 or after a predetermined time to perform printing operation.

Title: Driving method and device for multielectron source and picture forming device using the above
Inventor: TODOKORO YASUYUKI
IPC: H01J1/30
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To improve the production yield by supplementing the operation of an electron emitting element, in which a defect is generated, by an adjacent electron emitting element when a defect is generated in a formed electron emitting element. SOLUTION: A row direction driving section 16 successively selects row direction wires 12. If there exists no defective element on the row direction wire selected by the section 16, a selected voltage (for example, -7V) is applied to the selected row direction wire. A column direction driving section 17 applies a driving voltage (for example, +7V) to a column direction wire based on video signals and drives electron sources. If a defective element in the row direction wire selected by the section 16 exists, a driving voltage is applied to an adjacent row direction wire and the driving of the electron source is conducted by applying a selected voltage to a column direction wire. Thus, the operation of the row, in which a defective element exists, is compensated for by the electron source of the row that is adjacent to the row in which a defective element exists.

Title: Friction material and manufacture thereof
Inventor: NAKAGAWA MITSUHIKO
IPC: F16D69/02
Filed: 1990-08-29
Abstract: PURPOSE:To solve sanitary and environmental problems and to prevent any deterioration in brake performance and any squeaking noise at the time of braking by incorporating a mineral having a plain reticular crystal structure into a granule body, and aligning the direction of separation between the crystal layers of the mineral substantially along the frictional surface of a frictional material. CONSTITUTION:A granule body for regulating friction or abrasion includes a mineral having a plain reticular crystal structure. The mineral is dispersed in such a manner that the direction of separation between crystal layers is aligned substantially along the frictional surface of a frictional material. Accordingly, the granule is likely to generate fine separation on the frictional surface due to a frictional resistance caused by the contact between a brake pad and a disk at the time of the friction so that a stick slip phenomenon can be restrained, and further, any squeaking noise can be effectively prevented at the time of braking while preventing to the utmost a deterioration in brake performance due to a decrease of a frictional coefficient which leads to a fatal wound to the frictional material.

Title: Picture reader
Inventor: SAKURAI YASUO
IPC: H04N1/04
Filed: 1989-09-06
Abstract: PURPOSE:To detect even an original size by making the read position of a read optical system coincident with an original size detection line and moving the read optical system onto a picture read line before the tip of the original reaches the picture read line. CONSTITUTION:A tip of an original D fed by the drive of an ADF motor is detected by an original detection sensor 12 at a point A and the original reaches an original size detection line B after a time X. The read optical system is in standby at that point of time while the read position is made coincident with the line B, the read optical system reads the width of the tip of the original (original size) for a time alpha and the original is moved to the picture read line C by the start of the main body motor. Since a black color of an original retainer 13 exists at the rear face of the original whose background is in general white in the original size detection line B, a CCD 8 of a read optical system identifies clearly the border between the original and the retainer 13. Thus, the original size is detected.

Title: Method for checking mask pattern
Inventor: OE RYOICHI
IPC: G03F1/00
Filed: 1985-10-15
Abstract: PURPOSE:To facilitate the process of conversion in to logical gates by referencing a previously registered table, by storing connection information separately for the transistors collected with respect to the output node and for the transistors collected with respect to the branch node for each group. CONSTITUTION:As to the method for storing into a matrix, a basic method is that the gate numbers of transistors obtained by tracking with one power supply node VSS, VDD are stored in the row (or column) direction. However, if they are collected in the branch node once and the tracing is performed again therefrom, the number of that branch node is stored. Since the connections of the transistors are traced and the transistor circuits are grouped so as to constitute one gate respectively, without recognizing whether the transistor connection is serial or parallel as has conventionally been done, and thereafter respectively storing the connections of the transistors within each group into the matrix separately for two classes, the branch node and the output node, it is easy to recognize the connection status and advantageous to reference to the previously registered table.

Abstract: PURPOSE: To keep a time constant of the transient characteristics always in a thermally balanced state and reduce the variation of regulation by a method wherein a time sequence related to control is so predetermined as to fix the time constant of the transient characteristics related to the monitor output of an emitted luminous power. CONSTITUTION: In a laser unit 13, the emitted luminous powers of a mode switching signal and a light emission signal are detected by a power meter 205 as monitor outputs and the laser trimming is controlled by a laser trimmer 201 and a trimming resistor 208 on the laser unit 13 is trimmed. In order to avoid the change of the characteristics, the lapse of time from the starting time of the regulation is controlled by a timer routine and, in order to avoid the change of the finishing time of the regulation, the regulation mode is finished at the predetermined regulation time T1-T5. After the regulation is finished, a mode switching is performed at the mode switching time T6-T9 with a timing which is always fixed by the previous timer routine. Thus, the time constant of the transient characteristics is fixed.

Title: Electric double layer capacitor

IPC: H01G11/22
Filed: 1989-09-07
Abstract: PURPOSE:To enhance a pressurization efficiency by a method wherein a gasket is formed by a hardening and molding operation so as to be thinner than a thickness of a polarizing electrode which has been filled with a liquid gasket material of a room-temperature hardening type. CONSTITUTION:A recessed part 8 surrounded by a liquid gasket material 60 with which a collector 1 has been coated is filled with a paste-like polarizing electrode 4. Then, a separator 3 is placed on the filled polarizing electrode 4. While the separator is pressed by using rollers 9 and is being degassed, the separator 3 is bonded. Since the liquid gasket material 60 is compressed and molded at this time, the liquid gasket material 60 of a room-temperature hardening type is compressed and hardened to form a gasket 6. A distance in an up-and-down direction between collectors 1, 2 at parts of gaskets 6, 7 is smaller than that in other parts 6, 7. Thereby, when an electric double layer capacitor is pressurized during its use, a pressurization force is used exclusively to compress polarizing electrodes 4, 5 and an efficient pressurization operation can be executed.
