Title: Fixing method of bead core
Inventor: MIZUYAMA MASAMI
IPC: H01F38/42
Filed: 1994-07-01
Abstract: PURPOSE:To fix a bead to a lead wire only with a thermal contraction tube, by mechanically stretching and expanding a thermal contraction tube having an inner diameter larger than the outer diameter of a lead wire by using a jig, covering a bead core with the tube, inserting a lead wire into the bead core, and contacting the thermal contraction tube by heating. CONSTITUTION:Lead wires 2, 3, 4 are bundled, and in this state, covered with a thermal contracrion tube 5 for protecting the lead wires. Then the tube is thermally contrated, and the lead wires 2, 3, 4 are inserted into the bead core 6. By using a tube inner diameter enlarging jigs 11, 12, the inner diameter of the thermal contraction tube 8 is mechanically stretched and expanded, and the bead core 6 is covered with the tube 8. Hot air is blown against the thermal contraction tube 8 covering the bead core 6 by using a blower or the like, and the tube is contracted by the heating. Hence the bead core 6 is surely fixed to the lead wires 2, 3, 4, so that binder is made unnecessary, and material cost and working cost can be reduced.

Title: Vacuum pump of magnet type
Inventor: NEMOTO TOSHIO
IPC: F04B45/04
Filed: 1990-06-08
Abstract: PURPOSE:To prevent exhaust air from remaining by forming the inner wall of a pump room into a curved surface in a dry vacuum pump of magnet type for obtaining dry high vacuum. CONSTITUTION:Air is sucked into a first stage pump room 7 through an inlet valve 6. Then the polarity of a coil mounted around a first stage core 4 is changed so as to cause a diaphragm 2 to move downward and air sucked into the first step pump room 7 is fed into a second stage pump room 8 accordingly. In this case, movement of the air from the first stage pump room 7 to the second stage pump room 8 is achieved through the center hole 9 of the diaphragm. When the diaphragm 2 is moved downward a built-in diaphragm 1 is separated from the upper portion of the diaphragm 2 so the center hole 9 is opened. When the diaphragm 2 is moved upward the built-in diaphragm 1 makes sealing contact with the upper portion of the diaphragm 2 so the center hole 9 is closed.

Title: Operating method for blast furnace and gas blowing mechanism into blast furnace top
Inventor: KAJIWARA YOSHIMASA
IPC: C21B5/00
Filed: 1978-12-06
Abstract: PURPOSE:To make it possible to control arbitrarily the gas flow in a blast furnace, by arranging gas blowing means of specific structure in the space formed above the charged raw material at the blast furnace top. CONSTITUTION:Plural gas blowing means 18 are so arranged in circumferential direction at the top of a blast furnace 4 that these means are movable freely into the furnace. When a deposit 10 is formed at the inner wall, an injection box 2 facing to the section where the deposit is formed is made to advance into the space above the raw material 11 by the operation of a reciprocative means 3 such as a hydraulic cylinder, and nonoxidizing gas such as CO, CO2, N2 etc. is sent pressurized through a gas charging pipe 5 and is blown into the furnace through injection holes 1. Hereby, the gas flows in the furnace are led to the section above- described region collectively so as to accelerate the disappearance of the deposit. Blowing of the gas to the central part of the furnace restrains the slagging phenomena in the molten region.

Title: Constant voltage circuit
Inventor: YAMAMOTO KATSUMI
IPC: H03F1/52
Filed: 1987-06-18
Abstract: PURPOSE:To obtain a constant output voltage by preventing dispersion in an overcurrent detecting level from being generated, by using an overcurrent detecting transistor, a comparator, a reference voltage circuit and a constant current source in a constant voltage circuit using an overcurrent prevention circuit. CONSTITUTION:An overcurrent flows on a resistor 11, and a voltage due to voltage drop is compared with the output of the reference voltage circuit 13 by the comparator 12. When the former is larger than the output of the voltage circuit 13, the overcurrent detecting transistor TR4 is turned ON, and a TR6 is also turned ON. Thereby, the overcurrent can be prevented from being generated by turning OFF a TR9 via the TR6. Thus, by adjusting the resistor 11 and the voltage circuit 13 without being conscious of the dispersion in the V of the overcurrent detecting TR4, it is possible to set a constant overcurrent detecting level at a desired value.

Abstract: PURPOSE:To control etching precisely by using anisotropy etchant as an etchant which does not contain alkaline ion, by using anti-corrosive metal for a counter electrode and by using an ion sensitive field effect transistor as a reference electrode. CONSTITUTION:Anisotropy etchant which does not contain alkaline ions is used as an etchant. Anti-corrosive metal is used for a counter electrode and an ion-sensitive field effect transistor is used as a reference electrode. The electric potential of a silicon substrate 1 which has a first conductivity against the reference electrode is set to an electric potential to be etched, and a silicon layer 2 having a second conductivity is set to an electric potential which is not etched. Since a silicon layer of a uniform thickness which is controlled precisely can be formed in this way, yield of elements can be improved, and reliability of a formed semiconductor device can be increased because alkaline ions such as potassium ions are not used for etching.
