Abstract: PURPOSE:To produce a thick steel plate enhanced in HAZ toughness or a thin steel sheet excellent in deep drawability by specifying the amt., size and the number of dispersed Mn oxide particles in a steel material having specified contents of Mn, Si and S. CONSTITUTION:A steel material contg., by weight, 0.1-3% Mn, <=1.5% Si and <=0.01% S and further various elements contained in the ordinary steel material, as required, is used. This steel material contains fine particles, the particle consists of an oxide and MnS, and the oxide consists of Mn oxide and Si oxide and contains 50-80wt.% Mn oxide, and the 30-2000 oxide particles having 0.1-10mum diameter are dispersed per 1mm<2> of the cross-sectional area of the steel material. Since many MnS particles are dispersed in this way, a thick steel plate enhanced in HAZ toughness and a thin steel sheet excellent in deep drawability are produced.

Title: Magnetic head circuit
Inventor: YOSHINAGA MAKI
IPC: G11B5/09
Filed: 1992-01-30
Abstract: PURPOSE:To enable high speed write by imparting a write current dependency to a clamp voltage for suppressing a flyback voltage generated in a magnetic head at the time of a changeover in a current direction. CONSTITUTION:An operating current of differential transistors Q6 and Q7 has a dependency upon a write current IW as IA+IW'. Then, since a collector potential of the transistor Q6 is determined by the operating current (IA+IW ')XRI, the write current dependency can be imparted to the clamp voltage of a write driver. That is, as a result of changing a signal amplitude to be increased in accordance with an increase of the write current IW under the transient state of the write driver, when DELTAi is increased, the clamp voltage V is increased accordingly so as to act to make DELTAt constant.

Title: Commodity vending registration data processor
Inventor: OSAWA HIDEAKI
IPC: G06F3/048
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To make precisely reconfirmable the registration content of a registered commodity from the display information of an operator display part with less display information quantity in a short time. SOLUTION: Whenever the vending of a commodity is registered, the commodity registration history data formed of a commodity name, the number of sales commodities and the amount of money of the commodity are accumulated and stored in the registration order. When a recognition command is inputted, a prescribed number of commodities registration history data are read and the commodity name is simplified for every commodity registration history data. Thus, simple history data that can be displayed by one display line of a display is edited and data are sequentially displayed in the respective display lines of the display part.  When one piece of simple history data among a plurality of pieces of simple history data is selected, at least the commodity name, the number of sold commodities and the amount of money of sales of commodity registration history data corresponding to the piece of simple history data are displayed in the display lines of the display part. Thus, detailed information can be displayed.

Title: Gas insulated machinery and apparatus
Inventor: HANAI MASAHIRO
IPC: H01F27/32
Filed: 1991-03-06
Abstract: PURPOSE:To prevent the generation of fine gas gaps and partial discharge due to material contraction, by using elastic material like rubber and elastomer subjected to high temperature annealing, as constituent material. CONSTITUTION:For electrostatic shielding a press board 1 being solid insulator is used as core material. Its surface is coated with a polyester film 2 on which aluminum is vapor-deposited, thereby constituting a conducting part. In order to prevent the generation of gas gaps in end portions of the conducting part, packing is formed of silicon rubber 3 as elastic material like rubber and elastomer, so as to conform with the shape of the conducting part, and brought into contact closely with the conducting part. Said packing is fixed by winding an insulative film 4. When the temperature is raised as the result of drying and operating, the insulative packing 3 scarcely contracts. Thereby the generation of gas gaps and partial discharge due to the axial direction contration of the insulative packing 3 for electrostatic shielding can be prevented.

Title: Color image forming device
Inventor: HANEDA SATORU
IPC: G03G21/00
Filed: 1989-02-21
Abstract: PURPOSE:To attach and detach a process unit which integrates a cleaning device and a photosensitive drum without the falling and scattering of toner by bringing a cleaning means into the press-contact with an image carrier when the process unit is removed. CONSTITUTION:An image forming device releases the press-contact of the cleaning member constantly except image forming or cleaning operation. In this device, a frame 3904 is brought into condition where the image carrier 30 is brought into press-contact with the cleaning means by the action of an extension spring 3906 at the same time as the ejection of the cartridge even when the press-contact is released after finishing image forming. Therefore, when the cartridge is pulled out of the device main body, each the cleaning member is constantly press-fixed to the periphery of the image carrier 30. Thereby, the falling and scattering of the remaining toner at the time of the remove and operation of the cartridge can be effectively prevented while the cartridge is attached and detached or handled.

IPC: G01N27/72
Filed: 1987-02-24
Abstract: PURPOSE:To rapidly measure residual austenite with high accuracy by a small- sized apparatus, by providing an AC magnetic field generator, a detection coil and a signal processing circuit. CONSTITUTION:An AC magnetic field generator 1 is constituted of a field coil 101 and a sine-wave oscillator 102, and the output current of the oscillator 102 is applied to the coil 101 to generate an AC magnetic field. The specimen 3 inserted in a detection coil 201 is arranged in the coil 101 or in the vicinity of the end surface thereof and the AC magnetic field is applied to the specimen 3 to constitute a magnetic circuit. The AC signal voltage due to the AC magnetic field is induced at the terminal of the coil 201 but the amplitude value of the signal voltage corresponds to the AC magnetic characteristic of the specimen 3, that is, the residual austenite quantity thereof. The AC signal voltage is applied to a signal processor 4 which in turn converts the amplitude of the AC signal voltage to DC voltage. Therefore, the absolute value component of the AC signal voltage outputted from an output amplifier 405 represents the residual austenite quantity of the specimen. By this method, residual austenite can be rapidly measured with high accuracy by a small-sized apparatus.
