Filed: 1988-02-01
Abstract: PURPOSE:To obtain a dial pulse with high quality by providing an addition circuit including a semiconductor switch and bypassing a termination circuit in case of relaying the dial pulse thereby eliminating the distortion of a waveform due to amplitude fluctuation of the dial pulse caused by the impedance of the termination circuit and due to deterioration in the duty ratio. CONSTITUTION:A line is connected by turning on a loop control switch 4 by an ON/OFF hook signal by a receiver from a subscriber station, a pulse width expanding circuit 2 operated by the hook signal discriminates the ON/OFF hook signal and the dial pulse signal and drives a switching transistor(TR) 1 in case of the dial pulse. Then the switching TR 1 is turned on synchronously with the dial pulse to short-circuit the termination circuit 5 and the dial pulse not affected by the termination circuit 5 is sent to the exchange station side. Thus, the fluctuation of the amplitude of the dial pulse sent to the exchange station by the impedance of the circuit 5 and the disturbance due to the waveform deformation is prevented.

Filed: 1988-02-03
Abstract: PURPOSE:To detect the chromatic aberration which is the characteristics of an optical system with high accuracy and good operability by calculating the quantity of defocusing from the position signal of a secondary image by a photodetecting element. CONSTITUTION:The luminous flux from a light source 2 is converged and incident on a spectroscope 4 through a lighting optical system 3 and diffracted spectrally, and light corresponding to the set wavelength of the spectroscope 4 is projected from a pinhole 5 to form a pinhole image 7 through a lens 6 to be inspected.

Title: Leak inspection method for vessel having welded structure
Inventor: AKABOSHI KENJI
IPC: B65D8/22
Filed: 1993-01-19
Abstract: PURPOSE:To allow accurate location of leak point in a short time at low cost by blowing inspection gas, e.g. helium gas, to a welded part on the inner face side and detecting the inspection gas leaked through pores. CONSTITUTION:When a joint is subjected to leak test, a vacuum pump 6 evacuates microspaces on the joint face through a pipe screw 19. It is not possible that the plate face and the end face are perfectly smooth at the abutting part, i.e., the joint face, of plate materials 11, 12 and the air is sucked from the joint face through microgaps thus evacuating the microspaces. Consequently, leak can be detected by moving a nozzle discharging helium gas along the continuously welded part 16 on the inner face side at a joint. This method allows immediate detection of leak point, if any, and accurate location of the leak point.

IPC: H01M6/16
Filed: 1986-02-05
Abstract: PURPOSE:To improve the preserving property and low-temperature performance of a battery having lithium as an active material, by dissolving a solute such as lithium perchlorate in a mixed solvent comprising dioxolan and an alkoxide, to make a nonaqueous electrolytic solution for the battery. CONSTITUTION:A battery with a nonaqueous electrolytic solution is composed of a negative electrode whose active material is lithium or an alloy containing lithium, a positive electrode manufactured by the pressure shaping of a positive electrode depolarizing mix made by mingling manganese dioxide or the like with an electroconductive agent and a binder, and the nonaqueous electrolytic solution made by dissolving a solute such as lithium perchlorate in a mixed solvent comprising dioxolan and an alkoxide. The cations of the dioxolan, which are produced in the preservation of the battery, are captured by the alkoxide to suppress chain reaction to prevent the polymerization of the dioxolan. The preserving property and low-temperature performance of the battery with the nonaqueous electrolytic solution are thus improved to widen the range of use of the battery.

Title: Image forming method
Inventor: INOUE TETSUO
IPC: G03G13/01
Filed: 1978-03-03
Abstract: PURPOSE: To prevent a charger from becoming complex and to form an electrostatic latent upon  a transparent insulated layer by wholly separating the charge and an image exposure.   
     CONSTITUTION: The charge is held on a transparent insulated layer 1 by the primary charge  through a charger 10 to generate a surface potential. The charge on the layer 1 is erased by the  secondary charge at the opposite polarity through a charger 11 while the charge on a photoconductive layer 2 is held. An original 12 is then subjected to image exposure so that the charges  corresponding to a white portion are erased while the charges are held only at the layer 2 corresponding to a black color. Then, the AC discharge is performed by a charger 13 so that the surface potential of the photosensitive element is reduced to zero. At this time, among the charges corresponding to the black color, the charges between the layer 2 and the conductive layer 3 are distributed again. By the whole exposure, the charges on the layer 2 corresponding to the black color  are erased in response to reduction in the reisistance of the layer 2. As a result, only the portion  corresponding to the charges on the layer 1 are left. Thus, the surface potential corresponding to  the black color is raised so that the electrostatic latent image corresponding to the original image  can be formed.

Abstract: PURPOSE:To avoid interruption of printing or becoming in an out time state on a host apparatus side, by a method wherein the title printer is so constructed that when printing paper is exhausted in a hopper during printing operation, paper is fed by changing the hopper by another hopper to perform printing. CONSTITUTION:When a printing data sent from outside through an interface circuit 1 is received, an auto-sheet-feeder control circuit 4 selects a hopper to be used following a program stored in a ROM 5 and, besides, checks the presence of paper in said hopper, for instance, a hopper 3a.

The next paper is fed again with the auto-sheet-feeder control circuit 4, and printing is successively performed. Hereinafter, the presence of the paper in the selected hopper 3a is checked in the same way. If no paper is detected, in order to change the using hopper 3a, another hopper 3b is selected, and paper is fed in the same way to perform printing.
