Title: Copying machine
Inventor: ITO HIDEO
IPC: G03G21/00
Filed: 1987-07-27
Abstract: PURPOSE:To set one-surface document/both-face copying mode and to execute both-face copying without consideration of a user about the number of sheets of a document by installing an ejection control means for ejecting paper outside a copying machine and a waiting control means for keeping the paper waiting in a paper resupply means till plural actions by the next supply of document. CONSTITUTION:The titled machine has the ejection control means for ejecting the paper outside the copying machine without forming a copied image on the back surface of the paper, as it is, at the time of deciding that the number of sheets of a document is >=2 and stopping copying actions in a state where copying paper is housed in the paper resupply means 103, and the waiting control means for keeping the copying paper waiting in the paper resupply means until the copying actions by the next supply of the document at the time of deciding that the number of sheets of the document is not >=2 and stopping the copying actions in a state where the copying paper is housed in the paper resupply means 103. Thus both-face copying is made possible in the one-surface document/both-face copying mode even if the document is set on the document platen part 351 of an ADF (automatic document feeder) 300 one by one, and the paper is automatically ejected outside the copying machine if odd sheets of document more than three are set on the document platen part 351 of the ADF.

Inventor: SUZUKI MASAHIKO
IPC: H01J23/26
Filed: 1991-07-02
Abstract: PURPOSE:To provide a traveling wave tube having a slow-wave circuit of which the loading element is less likely to deform. CONSTITUTION:Metallization faces 13 are formed on both sides of an elongated dielectric member 12 extending along a tube axis Z, and two blades 14 are bonded, using brazing material 15, to the metallization faces 13, respectively, to thereby construct a loading element. By this, since the two blades are supported by the dielectric member, the loading element is less likely to deform. Further, the interval between the blades is kept constant by the width of the dielectric member.

Title: Gradation display controller
Inventor: AOYAMA YASUTADA
IPC: G02F1/133
Filed: 1988-07-27
Abstract: PURPOSE:To produce gradation data with an inexpensive liquid crystal panel having a simple circuit and to attain the function of displaying gradation data inexpensively by outputting a dot pattern designated by a 2nd designating means and data on a dot of a phase designated by a 1st designating means. CONSTITUTION:In connection with 1st to 3rd signals outputted whenever main scanning, sub-scanning and one-dot scanning are performed, the 1st designating means 13 determines the phase of the dot pattern. In connection with various factors such as the color of an image to be displayed, its brightness, etc., the 2nd designating means 10 designates the dot pattern. For the data on an image displayed by picture elements currently scanned, the dot pattern is selected by taking consideration of the color of picture element composing an image to be displayed, its brightness, and factors affecting the dot pattern. The dot pattern is phase-shifted by the amount designated by the 1st designating means 13 on a line or frame basis. Thus, by combining a simple circuit with a conventional liquid crystal panel and a conventional display controller, the function of displaying gradation can be achieved inexpensively.

At a point C, a solenoid 8 becomes on by a timer 7, a vertical rod 11 formed as one body with a strain gauge 10 is locked, and at a point D, an electric conduction of a resistance welding is started, and the electric conduction is completed at a point E. In this case, the tip of the electrode 3 moves up and down in a shape of a curve by expansion of the materials 2a, 2b, abrasion of the electrode or scattering of a nugget of a weld zone. When the electrode 3 starts its ascent at the point E, the solenoid 8 becomes off and the rod 11 is opened. In this way, a displacement of the tip of the electrode can be detected continuously irrespective of its abrasion.

Title: Liquid crystal driving device
Inventor: OMORI TETSUO
IPC: G02F1/133
Filed: 1991-07-26
Abstract: PURPOSE:To eliminate the need for an expensive analog amplifier and to reduce the cost of a system by installing capacitance type amplifiers which amplify the output signal voltages of sample holding circuits at a fixed amplification factor. CONSTITUTION:The analog output signal 2 which is outputted by a color palette 1 is sampled and held by (n) sample holding circuits 6-8 in a liquid crystal driving device 5 successively according to a sample holding clock 18 while still narrow in voltage amplitude. Sampled signals 9-10 are voltage-amplified by capacitance type amplifiers 19-21 respectively and outputted to a liquid crystal display unit. Thus, the voltages are amplified after being sampled and held to shorten the cycle of the voltage amplification to only the cycle of a display of one horizontal line, and the operation speed is made slow correspondingly to facilitate the design of the amplifiers. Consequently, the need for the high-speed, expensive analog amplifier is eliminated to obtain the driving device which is decreased in the constituent elements and low in system cost.

Abstract: PURPOSE:To prevent creation of noise due to the motion of a fuel pump, by a method wherein the number of revolutions of the fuel pump is controlled so that its high harmonic component is present within the range of the given frequency of noise created by an engine during ilding of the engine. CONSTITUTION:The number of revolutions of a fuel pump 1 is detected by a detector 2 for the number of revolutions which outputs an output voltage proportional to the number of revolutions of the motor 1. A control circuit 3 is connected to the output terminal of the detector. Meanwhile, a voltage set circuit 4 generates an output voltage having a level depending on the load of an engine, and the output voltage is fed to the control circuit 3 which provides a control signal according to the output voltage of the detector 2 for the number of revolutions and that of the voltage set circuit 4. The drive circuit 5 of the motor 1 is connected to the output terminal of the control circuit 3, and the drive circuit 5 applies a voltage, having a level corresponding to the control signal, on the motor. The voltage applied on the motor 1 goes to a voltage proportional to the output voltage of the voltage set circuit 4, and thereby, during idling, the voltage applied on the motor 1 decreases, also resulting in reduction in the number of revolutions of the motor 1.
