Title: Power supply
Inventor: NARUO MASAHIRO
IPC: H02M7/5387
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a power supply that reduces the fluctuation width of switching frequency and by making not all switching elements perform hard switching, makes it possible to adjust the load output over a wide range. SOLUTION: A circuit CTR controls so as to make the timing of turning almost equal on a switching element Q2 and another switching element Q3 arranged at the diagonal position to the one Q2, when a load output is lowered so that 'on' time of the switching element Q3 is shortened. Specifically, when the duty ratio of he switching element Q3 is minimized, no hard switching is effected so that the load output can be adjusted in a wide range, without increasing the stress or noise.

IPC: E02D1/02
Filed: 1994-10-31
Abstract: PURPOSE: To surely execute a penetration test and moreover to improve the safety of work by equipping a penetration tester with a safety device for preventing malfunction. CONSTITUTION: The safety device of a penetration tester 1 is composed of an upper-limit sensor 2a, a lower-limit sensor 2b, an an approach sensor 21 and a control section 22. In the case of a penetration test, when a loading base 3 attains a lower-limit position as the penetration rod 10 penetrates, this attainment is detected by the lower-limit sensor 2b, and the control section 22 issues a command on the signal from the sensor 2b to stop the drive of a motor 4. After that, when the penetration rod 10 is added, and a chuck unit 6 is operated for releasing the hold of the penetration rod 6, the approach sensor 21 detects this state to actuate an elevating drive source 7 for making the loading base 3 ascend.  When the loading base 3 attains the upper-limit position, and the upper-limit sensor 2a detects this attainment and confirms the penetration rod 10 held by the chuck unit 6, the control section 22 outputs a driving command to the motor 4 and stopping command to the elevating drive soure 7 at the same time to start the penetration test again.

Title: Manufacture of semiconductor device
Inventor: HASHIMOTO SAKAE
IPC: H01L21/322
Filed: 1989-11-27
Abstract: PURPOSE:To precipitate internal micro defective nuclei having high density efficiently while shortening a heat treatment time by employing a heat treatment method for continuously elevating the temperature extending over a moderate temperature region from a low temperature region in the formation of an inter nal fine defect nucleus region. CONSTITUTION:A silicon substrate 1 is thermally treated in a hydrogen gas atmosphere at a temperature of 1100 deg.C or higher prior to epitaxial growth, and thermally treated in a nitrogen gas atmosphere at a high temperature of 1100 deg.C, thus forming a nondefective layer 4 on the surface of the substrate 1. The temperature is then lowered to a fixed level, and elevated continuously extending over a moderate temperature region from a low temperature region in an oxygen gas atmosphere, and a fine defect nucleus region 3 formed in the substrate 1. Accordingly, internal defect density of approximately twice as dense as a conventional method is acquired while the time required for heat treatment can be shortened, thus improving productivity.

Title: Liquid helium level measuring instrument
Inventor: MORIYAMA TAKASHI
IPC: G01F23/22
Filed: 1986-12-23
Abstract: PURPOSE:To prevent liquid level measurement from being affected by the temperature dependency of the resistance of a superconductive wire by calculating the liquid level of liquid helium on the basis of a reference combined resistance value from memory means and a combined resistance value from combined resistance calculating means. CONSTITUTION:A superconductive wire 1 and a calibrating linear element 3 having resistance-temperature characteristics with reverse polarity are provided in parallel. A prescribed combined resistance value is calculated by combined resistance calculating means 17 on the basis of the values of resistance between both ends of the wire 1 and the element 3. At this time, since the wire 1 and the element 3 having the temperature dependency of resistance with reverse polarity to that of the wire 1 have the same temperature distribution, the inclination constants of the temperature-to-resistance value characteristics curves of both the wires 1 and the element 3 are set to be stored and used in calculation. Thus, since the effects of temperature dependencies can be canceled by each other, highly accurate measurement can be conducted.

Title: Dissolution off-gas treatment device
Inventor: TAKIMOTO YOSHINORI
IPC: G21F9/00
Filed: 1988-12-02
Abstract: PURPOSE:To contrive the relief of a corrosion environment by connecting a recirculating passage in which part of treated off-gas is circulated to an inlet gas passage of a dissolution off-gas device from the downstream portion of an exhauster. CONSTITUTION:A dissolution off-gas produced from a dissolver 5 of spent fuels is allowed to flow in an NOx treatment part 1, and NOx is absorbed by water herein to recover as nitric acid. Next, iodine in the gas is absorbed and eliminated by an iodine elimination part 2 to exhaust the gas from a stack 4 to the outside by an exhauster 3. Part of the gas is returned to the inlet part of the treatment part 1 through recirculation tubing 7 as the gas allowed to flow out from the exhauster 3 is controlled by a flow control valve 6. A shearing machine for shearing spent fuels is set in the upstream side of the dissolver 5. Air is enforcedly leaked by the shearing machine and sucked and exhausted by the exhauster 3 from the dissolver 5 to maintain negative pressure. Thereby, the corrosion by the residual iodine is prevented and the long life of the device can be contrived without the use of extreme anticorrosion materials.

Title: Flexible shaft joint
Inventor: HIROYASU MINORU
IPC: F16D3/38
Filed: 1993-12-06
Abstract: PURPOSE:To eliminate play by providing a first insertion part in a first connecting part so as to move in one direction orthogonal to an axis, a second insertion part in a second connecting part so as to move in one direction right-angled to the moving direction of the first insertion part, a first elastic part curved in the moving direction of the first insertion part, and a second elastic part curved in the moving direction of the second connecting part. CONSTITUTION:In the case of a second connecting part 26 being displaced in the moving direction (X-direction) of a first insertion part 26, the connecting part 27 can move only in one direction (Y-direction) right-angled to the X-direction in relation to a second insertion part 28, so that the connecting part 27 is displaced in the X-direction by the elastic deformation of a first elastic part 29 that can be curved in the X-direction integrally with the insertion part 28. At this time, a second elastic part 30 regulates the X-direction displacement of the connecting part 27 because of being disposed in the right-angled direction to the elastic part 29, but this regulation is released by the X-direction movement of the insertion part 26 connected to the second elastic part 30. The connecting part 27 is thereby displaced in the X- direction, and a driven shaft 4 can be displaced in the same direction. The Y-direction displacement of the connecting part 27 is performed in the same way, and the driven shaft 4 can be displaced in the same direction. There is thereby no play in the rotating direction caused by backlash.

At a back end part where the connection part 7 is not cut, it is kept as elongated without being curved.
