Title: Production of medium-carbon aluminum killed steel
Inventor: FURUKAWA MIKITO
IPC: C21C7/00
Filed: 1995-04-20
Abstract: PURPOSE: To produce a medium-carbon Al killed steel, in which carbon and Al concentrations are controlled with high precision, by applying closed-circuit degassing to a molten steel of high blowing out carbon content at a specific degree of vacuum, regulating free oxygen concentration to a specific value, and then regulating components such as Al. CONSTITUTION: A molten steel, in which the content of blowing out carbon is regulated to >=0.05% by blowing in a converter, is tapped into a ladle. In the course of this tapping, no deoxidation or slight-degree deoxidation is performed, and further, an Fe-Mn alloy and a carbon material are added, if necessary. The molten steel is charged into a vacuum degassing treatment apparatus, where the molten metal is circulated at about 20-150Torr degree of vacuum and the concentration of free oxygen in the molten steel is regulated to <=80ppm by using a deoxidizer, such as Al, and then degassing treatment is performed. During this treatment, component regulation is performed by adding Al or Al and alloying elements, as required.

Title: Igbt driving circuit
Inventor: ISHII SHINICHI
IPC: H03K17/16
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To reduce the high-frequency leakage current, and to easily switch the voltage change rate, by connecting each one of gate resistor and capacitor for forward and backward biasing to the gate of an insulated gate bipolar transistor(IGBT), and by connecting a semiconductor switch for mode switching to the other side of the capacitor for turning on/off. SOLUTION: A capacitor 13 is connected to the common point of a gate resistor 7 for forward biasing and a gate resistor 8 for backward biasing and the gate of an IGBT 9. One MOSFET 14 for switching a mode is connected to one side of the capacitor 13, and the other FET 14 is connected to the common point of a power supply 1 for forward biasing and a power supply 2 for backward biasing. When the FET 14 is turned off, a signal is inputted to an input 12 for switching the mode, the FET 14 is turned on, and the area between the gate and the emitter of the IGBT 9 is connected in parallel, thus changing a time constant for charging/discharging the gate when the IGBT is turned on/off and achieving an operation in a high/low voltage change rate mode.

Title: Ink jet head and manufacture thereof
Inventor: HIRATA SUSUMU
IPC: B41J2/055
Filed: 1995-05-17
Abstract: PURPOSE: To enhance response characteristics by heating/cooling to enable high speed printing by forming a plurality of fins alternately combined on the side of the substrate of a buckling structure and on the side of the buckling structure of the substrate and always opposing the fins each other at a narrow interval at least on the single side of them. CONSTITUTION: When voltage is applied to an electrode 14a, a buckling structure 1 is heated by the resistance heating of a heater 3 to extend in its longitudinal direction. However, since the end part in the longitudinal direction of the structure 1 is fixed to a substrate 7 and the structure 1 can not extend, compression force Po being reaction force is generated and accumulated in the structure 1 and, when the compression force Po exceeds buckling load, the structure 1 generates buckling deformation. When the structure 1 is deformed toward a nozzle plate 10 at its central part, the diaphragm 5 connected to the structure 1 is deformed toward the plate 10. Therefore, ink 17 is pushed out of a nozzle 11 and an ink droplet is formed to the outside of an ink jet head and injected to apply printing to a printing surface.  Next, a current is cut off and the structure 1 is cooled to return a standby state.

Title: Measurement of surface cleanness degree
Inventor: UDA MASAYUKI
IPC: G01N23/227
Filed: 1984-06-09
Abstract: PURPOSE:To accurately measure the surface cleanness degree of a specimen without relying on visual observation, by allowing a specimen to emit electrons from the entire surface thereof by applying energy having a specific value to said specimen and detecting electrons from the surface not covered with a contamination layer. CONSTITUTION:A specimen 7 having a contamination layer 9 adhered to a part of the surface thereof is irradiated with monochromatic light, which has energy equal to or more than the photoelectric function of the specimen but below that of the contamination layer 9, from a light source 10 through a spectroscope 11 and slits 12. Then, the electrons from the part covered with the contamination layer 9 are caught while electrons are allowed to discharge from the uncovered surface of the specimen 7 and the number of said discharged electrons are counted by a count means 16 through grid electrodes 6, 8, pulse generators 14, 15 and an amplifier 16 while the calculated result is outputted to an operation means 17 which in turn performs operation based on formula T=N/N1 (wherein N is the count number when the number of electrons from the surface not covered with the contamination layer are detected and N1 is the count number when the surface of the specimen is a perfectly cleaned one) to calculate a cleanness degree T. By this method, the surface cleanness degree of the specimen can be accurately measured.

Title: Thermal head
Inventor: NIKAIDO MASARU
IPC: B41J2/335
Filed: 1987-05-18
Abstract: PURPOSE:To simplify the production process and to reduce the size of a thermal head, by applying a high resistance layer mainly composed of glass or heat- resistant resin onto the main face of an alloy mainly composed of iron and chrome, thereby eliminating process for removing wave being formed during formation of a substrate or alkali component. CONSTITUTION:A high resistance substrate 21 comprises a metal substrate 22 of Fe-Cr alloy and a high resistance layer 23 of a glass layer formed thereon and containing 16 pts. wt. of PbO, 56 pts. wt. of SiO2, 9 pts. wt. of Al2O3, 4 pts. wt. of B2O3, 8 pts. wt. of CaO and BaO, Cr2O3, NiO, for example. When a reaction layer of spinel type oxidation layer 24 is provided additionally, adhesion of the glass layer 23 can be improved. Since no ceramic substrate is employed in the high resistance substrate, a process for removing alkali metal ions which causes degradation of the function of the heating element section is not required, nor required is the surface polishing process for removing wave being produced during formation of the ceramic substrate. Although Fe-Cr series alloy contains 5-30 pts. wt. of Cr in order to exhibit corrosion resistance against production process, said alloy can serve as a common electrode conductor, thereby, the size of thermal head can be reduced.

Abstract: PURPOSE:To perform preventive maintenance on an electric equipment which is smaller in space and low in cost by writing and reading out the integrated conducting time of the equipment in and from a memory whose storing content is protected and, when the integrated time exceeds a prescribed range, warning or displaying the state. CONSTITUTION:When the power supply is turned on, a microcomputer MC 4 reads the time data (starting from '0') written in an EEPROM 5 and stores the data in a RAM. In order to obtain the using time of a VTR 1, the MC 4 counts the time during which the power supply to the VTR 1 is turned on. Then the MC 4 increases the time data in the RAM read-out at every fixed time and the increased time data are written in the EEPROM 5 whenever the time data are increased. Then the MC 4 checks whether or not the time data in the RAM get into a prescribed range and, when the time data get into the prescribed range or exceed a prescribed value, makes a warning or alarming displayed on a display device 6. Therefore, the user of the electric equipment can recognize the necessity of repairing, inspection, parts exchange, etc., before the equipment becomes defective.
