Patent JP-H0275911-A (JP)
Title: Liquid level detector for sealed vessel
Inventor: HASEGAWA MASAYORI
IPC: G01F23/14
Filed: 1988-09-12
Abstract: PURPOSE:To accurately detect the liquid level in a sealed vessel by providing a differential pressure gage for detecting the differential pressure between the gas pressure of the upper section inside the vessel and the gas pressure inside a pressure detecting tube. CONSTITUTION:A reaction liquid sent from a reaction system operated under a high-temperature and high-pressure condition is injected into a sealed vessel 3 through a ball valve 11 and liquid pipe 1. As the level of the reacted liquid rises in the vessel 3, the pressure inside the vessel 3 rises. When the liquid level becomes higher than the opening 4 of a pressure detecting tube 5, an enclosed state is formed in the tube 5 by the liquid getting into the tube 5 and the gas inside the tube 5 is compressed in accordance with the volume of the liquid getting into the tube 5. As a result, the gas pressure inside the tube 5 becomes higher than the gas pressure inside the vessel 3. The differential pressure is outputted from a differential pressure gage 8 and converted into a liquid level by means of a converter 9 and the liquid level is indicated in a level indicator 10. Thus the liquid level in the vessel 3 can be measured accurately.

Title: Pipe reinforcing structure at bend propelling time in propelling construction method
Inventor: NAKAMURA AKIO
IPC: E21D9/06
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To smoothly perform a propelling construction method even in a curved part by allowing a reinforcing material to abut to an inner peripheral surface of the socket inmost end abutting to the inserting port tip in a pipe propelling construction method for propelling a pipe by pushing the inserting port tip against the socket inmost end. SOLUTION: A reinforcing material 8 forms a circular arc piece along the inside surface circumference of a propelling pipe 4 to abut in the circumferential direction along the edge of the socket inmost end 5a. A support column 9 is provided with an extensible/contractible device 9a in an intermediate part so as to pressingly arrange the reinforcing material 8 on the socket inmost end. The reinforcing material 8 is brought into pressure contact with an inside surface of a pipe 1 along the circumference of the socket inmost end 5a by extending the support column 9.  Thus, even if an abutting part of the inserting port tip 6a and the socket inmost end 5a is displaced since the propelling pipe 4 approaches a curved part of a pipeline, since the socket inmost end 5a is supported from the inside surface by the reinforcing material 8, or the inserting port tip 6a abuts to the reinforcing material 8, and since shaft directional force is received thereby, shear fracture of a pipe wall corner part is prevented so that the pipe can be smoothly propelled even in the curved part.

Abstract: PURPOSE:To omit a phase control with a stator simplified in its mechanical constitution by constituting a connecting vibrator by fixedly arranging two or more thickness sliding piezoelectric elements, having a thickness sliding vibration mode, with predetermined spaces on an annular thickness vertical piezoelectric element having a thickness vertical vibration mode. CONSTITUTION:In a connecting vibrator 10, two or more thickness sliding piezoelectric elements 16a, 16b, 16c having a thickness sliding vibration mode are fixedly arranged with predetermined spaces on an annular thickness vertical piezoelectric element 14 having a thickness vertical vibration mode.

Title: Assembly time equalizing method for mounting parts by a plurality of automatic assembling machines
Inventor: HIROTA SHIN
IPC: H05K13/04
Filed: 1988-09-12
Abstract: PURPOSE:To equalize the time of assembly easily by distributing parts to automatic assembling machines upon judging the parts arrangement relationship, and thereby eliminating possible generation of parts not mounted in the process of deciding the assembly sequence. CONSTITUTION:A parts arrangement relationship verifying means 1 checks the parts in mutual interference. An assembly priority order deciding means 2 gives priority in assembly to the checked parts in interference and allocates to the first automatic assembling machine of the assembly process. Those parts not in interference are classified by a priority order classifying means 3 type by and distributed to automatic assembling machines by an automatic assembling machine distributing means 4. If, at this time, the automatic assembling machine is fed with parts exceeding the total number decided by the inserting tact specified thereto, the surplus parts are allocated to other automatic assembling machines. Because the parts in interference are fist distributed in such a fashion, to be followed by distribution so that the automatic assembling machines are fed with parts equally, there is no fear of being differently fed at the time of assembly from the number distributed at the first.

Title: Semiconductor device
Inventor: NOGAMI KAZUTAKA
IPC: H01L21/822
Filed: 1990-08-31
Abstract: PURPOSE:To mount a circuit which is strong against electrostatic destruction, but weak against noise, and another circuit which tends to produce noise in a mixed state by providing a protective circuit on each wire and another protective circuit between the power source and ground of each circuit. CONSTITUTION:When noise is generated from the second circuit 3, the noise is not transmitted to the first circuit 2 through a power supply line 11 and ground line 12 depending upon the action of a protective circuit 14, because the field transistor and a transistor which is in a turned off state in an ordinary state are electrically opened in the range of ordinary operations. Therefore, even when the first circuit 2 is weak to noise, the circuit 2 is not affected by the noise from the circuit 3 and does not malfunction. In addition, even when a high voltage is applied across power supply pads 7 and 9, across ground pads 8 and 10, or across a separated power supply pad and one of the ground pads 8 and 10, no high voltage is directly applied across the transistors of the first and second circuits 2 and 3 and they can be protected from electrostatic destruction, since discharge takes place through protective circuits 14 and 15.

Filed: 1989-09-05
Abstract: PURPOSE:To enable pre-ionization and primary discharge to be smoothly carried out by a method wherein the diameter of a part of a pre-discharge electrode opposed to a primary electrode is so set as to make the electric field of the part concerned lower than the discharge electric field of gas laser medium in intensity, and the diameter of the tip of the pre-discharge electrode is made smaller than that of its part opposed to the primary electrode. CONSTITUTION:The diameter of a part of a pre-discharge electrode 6 opposed to primary electrodes 2 and 3 is made large enough so as to make the electric field of the part concerned lower than the discharge electric field of mixed gas 1 in intensity. The diameter of the tip of the pre-discharge electrode 6 is made much smaller than that of its part opposed to the primary electrode. That is, the part of the pre- discharge electrode 6 opposed to the primary electrodes 2 and 3 are formed large in diameter, whereby an electric field 10 of the opposed part becomes low in intensity and consequently voltage withstanding strength between the pre-discharge electrode 6 and the primary electrode 3 is sharply improved. On the contrary, the opposed parts of the pre-discharge electrodes 6 or the tips of the electrodes 6 are formed small in diameter, so that discharge starts easily between the pre-discharge electrodes 6. By this setup, pre-ionization and primary discharge following it are smoothly and stably carried out.
