| 20110272638 | FLUORINE INSOLUBILIZERS AND METHODS OF PRODUCING SAME - A fluorine insolubilizer capable of sufficiently insolubilizing fluorine within a short time contains calcium hydrogen phosphate dihydrate in an amount of 95-40 mass % and apatite hydroxide in an amount of 5-60 mass % for a total of 100 mass %. | 11-10-2011 |
| 20110222651 | PHASE SHIFT INVERTER, X-RAY HIGH-VOLTAGE DEVICE USING SAME, X-RAY CT DEVICE, AND X-RAY IMAGING DEVICE - There is provided an inverter circuit which allows a single drive circuit to carry out both the tracking control for tracking resonance frequency fluctuations caused by load fluctuations, and the power control, thereby reducing switching loss. An inverter drive circuit part obtains a phase difference between output current and output voltage directed to a load circuit which is connected to a midpoint of two arm circuits of the inverter circuit, and controls a phase of the driving signal directed to each of the semiconductor switches in such a manner that the phase difference becomes zero or a predetermined value. This allows an operating frequency of the inverter circuit part to track a resonance frequency of the load circuit. In addition, this enables a current phase to be delayed with respect to a voltage phase, thereby achieving ZCS. Since the phase difference between the output current and the output voltage is used, it is not necessary to use an auxiliary circuit to measure a current value in proximity to the semiconductor switches, thereby achieving a simple configuration. | 09-15-2011 |
| 20110011704 | NON-CONTACT CONVEYANCE SYSTEM - A non-contact conveyance system of the invention has a static pressure table for levitating a conveyance object upward, a pair of conveying units having vibrating plates and actuators and a moving unit for moving the conveying units in a conveying direction. Then, retaining forces are applied to front and rear edge portions of the conveyance object facing to the vibrating plates by exciting deflection standing waves in the vibrating plates by the actuators. Then, when the conveying units are moved while applying the retaining forces to the edge portions of the conveyance object, the conveyance object is conveyed following the move of the conveying units. Thereby, a number of parts may be cut and the system may be downsized. | 01-20-2011 |
| 20100280398 | LASER DOPPLER BLOOD FLOW MEASURING METHOD AND DEVICE - [Subject] To provide laser Doppler blood flow measuring method and device which achieve multi-dimensional measurement efficiently at a high degree of accuracy over a wide range with a simple optical system and device. | 11-04-2010 |
| 20090127128 | MEMBRANE-ELECTRODE ASSEMBLY, ELECTROLYTIC CELL EMPLOYING THE SAME, ELECTROLYTIC-WATER SPRAYER, AND METHOD OF STERILIZATION - The present invention provides a membrane-electrode assembly which comprises: at least one rod-form or tubular electrode; a tubular diaphragm disposed around the periphery of the electrode; and a wire-form counter electrode disposed around the periphery of the diaphragm, the diaphragm being fixed to the rod-form or tubular electrode with the wire-form counter electrode to thereby form an electrode chamber having a gas/liquid passage between the diaphragm and the rod-form or tubular electrode. | 05-21-2009 |
