Title: Identification of mutation of dna and device therefor
Inventor: TERUNUMA HIDEYA
IPC: C12Q1/68
Filed: 1994-05-24
Abstract: PURPOSE:To provide a simple method enabling the identification of the mutation of a sampled DNA only by dissolving the DNA in water, etc. CONSTITUTION:This method for identifying the mutation of a DNA comprises projecting prescribed light on the sampled DNA, simultaneously continuously changing the temperature of the DNA, measuring the changes in the absorbance by the temperature, and thus measuring a temperature for the dissociation of the double strands of the DNA into the single strands. When the DNA is heated at a specific temperature, the hydrogen bonds of the double strands are cleaved to form the single strands with the heat energy. A large change in the absorbance is consequently caused. Since the hydrogen bonds maintaining the double strands are determined by the kinds and number of the bases of the DNA, the heat energy, i.e., temperature for cleaving the hydrogen bonds can be measured by the large change in the absorbance to identify the mutation of the DNA.

Title: Ttl compatible cmos integrated circuit
Inventor: FUWA MASAHIRO
IPC: H03K19/0185
Filed: 1983-07-25
Abstract: PURPOSE:To drive a CMOS integrated circuit directly from a TTL integrated circuit by arranging a power supply for the CMOS integrated circuit independently of a power supply for the TTL integrated circuit and setting up the power supply voltage of the CMOS integrated circuit lower than that of the TTL integrated circuit. CONSTITUTION:The TTL compatible CMOS integrated circuit is connected so that the CMOS integrated circuit 34 to which Vcc2 33 is supplied is directly driven from the TTL integrated circuit 31 to which Vcc1 30 is supplied and constituted to output the Vcc2 33 from a constant voltage circuit 32 to which the Vcc1 30 is inputted. The Vcc1 30 is usually +5V, but the Vcc2 33 is set up to +3V by the circuit 32 controlled so as to output a constant voltage. Since the power supply voltage of the circuit 34 is set up to +3V lower than that of the circuit 31, the threshold of the circuit 34 is matched with that of the circuit 31, so that an ordinary pull-up resistance termination or a level converting element such as a level converting circuit based upon the circuit 34 is made unnecessary and the CMOS integrated circuit can be directly driven from the TTL integrated circuit.

Title: Activating method for hydrogen peroxide electrode for oxygen electrode
Inventor: HARADA KENJI
IPC: G01N27/38
Filed: 1980-09-29
Abstract: PURPOSE:To enable restoring of activity of surfaces of deteriorate anode and cathode in a manner to attach an electrode to a measuring device, by a method wherein a given inverse voltage is applied so that a platinum anode for electrode forms a cathode and a silver cathode for electrode forms an anode. CONSTITUTION:A diaphragm-covered electrode for detecting hydrogen peroxide consists of a platinum anode 1, a silver cathode 3, and a fixed ferment film 4, and a specific voltage is applied at a range of 0.6-0.8V between the platinum anode 1 and the silver cathode 3. If an electrode is reduced in its activity for the long use, an inverse voltage of a given voltage being applied is applied for 20-60sec through the operation of a changing-over switch so that the platinum anode 1 forms a  cathod, and the silver cathode forms an anode. If the voltae is restored to the specific voltage after the inverse voltage is applied, a residual current is high for the duration of 10min, and it is unsuitable for the measurement of a material which produces a dilute hydrogen oeroxide solution or a minute amount of a hydrogen peroxide. The residual current, however, becomes low 20mi later, and the measurement can take place.

Title: Composite magnetic head
Inventor: KASHIWA KAZUO
IPC: G11B5/31
Filed: 1985-06-21
Abstract: PURPOSE:To prevent the crosstalk between a thin film magnetic head for recording and reproduction and erasing head by integrally forming both heads via a nonmagnetic plate. CONSTITUTION:The thin film magnetic head 1 having a gap (g) for recording and reproduction and the erasing head 13 having a gap g' for erasure are united to one body by a technique such as welding. On the other hand, respective cores 14, 15 of the erasing head 13 are formed of a magnetic material having the coefft. of thermal expansion approximately equal to the coefft. of thermal expansion of a substrate 2 so that strain, etc. are not generated in these heads 1, 13 when used as a composite magnetic head. The previous signal is thoroughly erased by the erasing head 13 by moving the magnetic disk in an arrow X direction and thereafter recording is executed by the thin film magnetic head 1 and therefore the composite magnetic head which can make satisfactory recording and reproduction even when a magnetic recording medium having high coercive force Hc is used to meet the trend toward the higher density recording is obtd. The signal reproduced by the gap g' of the erasing head 13 can be shielded by the nonmagnetic plate 10 by which the crosstalk between the heads 1 and 13 is prevented.

Title: Plating device for semiconductor wafer
Inventor: SOEYAMA NORIO
IPC: C25D7/12
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To make the thickness of plating uniform by forming a cathode electrode so as to come into contact with substantially the entire periphery of a wafer and forming an anode electrode to an umbrella shape which is high at its center and parts from the wafer toward the periphery. SOLUTION: The plating treatment is executed by gushing a plating liquid 7 upward from a liquid discharge port 3 and passing prescribed current between the anode electrode 15 and the cathode electrode 14c while bringing the liquid into contact with the wafer 11 surface. The cathode electrode 14c is annular and feeds electricity to the entire circumference of the outer periphery of the wafer 11 by coming into contact therewith and, therefore, there are no more variations in the plating thickness in a circumferential direction even if the ground surface metallic layer of the wafer 11 is not sufficiently thick. The anode electrode 15 is arranged to the umbrella shape high in the center near to the wafer 11 and distant at the circumference and, therefore, the increasing difficulty in the flow of the plating current near to the center of the wafer is negated by the resistance of the ground surface metallic layer and the plating current is eventually passed uniformly over the entire surface of the wafer 11.

Title: Resistance spot welding gun
Inventor: SHIRONITA MASAO
IPC: B23K11/11
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To facilitate spot welding even for a welding position that is normally difficult to perform welding because of a positional restriction. SOLUTION: In a robotic welding gun, one electrode tip 5 is supported by a movable gun arm 2 while the other corresponding electrode tip 6 is supported by a fixed gun arm 1, with the movable one 2 connected to the fixed one 1 through a hinge 3 and designed to move circular-arcuately around the hinge 3 by means of a driving rod 9 of a pressurizing actuator 8 that is supported by the fixed gun arm. In this case, as a condition, the movable gun arm 2 or the driving rod crosses the fixed gun arm 1 at a position essentially away from the hinge 3 to the electrode side. As a result, spot welding can be easily performed on a lap joint formed on the inside of a box-shaped workpiece, a position hardly weldable by a usual C-type and X-type welding guns because of the positional restriction, so that the usage of a spot welding gun is expanded.

Title: Multitubular heat exchanger
Inventor: SANADA MASARU
IPC: F25B39/02
Filed: 1992-05-28
Abstract: PURPOSE:To prevent a decrease in a heat transfer rate and to improve a heat exchanging efficiency by arranging a valve unit for opening/closing an end of part of a heat transfer tube in an inlet or outlet chamber in a heat exchanger in which many heat transfer tubes are arranged between the inlet chamber and the outlet chamber through a heat exchanging chamber. CONSTITUTION:Left side cylinder chambers of cylinders 13a, 13b communicate with an inlet chamber 3, and right side cylinder chambers communicate with an outlet chamber 4 through a pressure guide tube 18. If a flow rate of refrigerant increases in a state that a pressure guide valve 19a is closed, a valve body 16a closes a heat transfer tube 1a and a pressure guide valve 19b is opened, a pressure difference between the chambers 3 and 4 is increased. As a result, since a piston 14b is moved to a right side against an energizing force of a spring 17b, a valve body 16b is moved back through a rod 15b, and a heat transfer tube 1b is maintained open. When the flow rate of the refrigerant is reduced as a refrigerating load is decreased, the pressure difference between the chambers 3 and 4 is reduced. As a result, the piston 14b is moved to the left side by the force of the spring 17b, and hence the body 16b is moved forward through the rod 15b to close the tube 1b.
