Title: Control device and control method for power conversion system having instantaneous voltage drop-service interruption counter-measure functions
Inventor: SHIMOMURA JUNICHI
IPC: H02M7/48
Filed: 2007-12-10
Abstract: Intended is to suppress such fluctuations of a PCS AC voltage in a power conversion system as might otherwise be caused at a changing time of a ''self-contained'' run by instantaneous voltage drop / interruption of service. At an ordinary time of a stable system voltage, a change switch (25) is changed to the output side of an APR control circuit (22), and a change switch (400) is changed to the output side of a charge/discharge running time PWM command value creating unit (200), so that the power conversion system is run in a charge/discharge run mode. When the instantaneous voltage drop / service interruption occurs, the change switch (25) is changed to the output side of a before self-contained run current command value creating unit (60), so that the constant current discharge run for discharging for a predetermined time period is performed with the current command value of the before self-contained run current command value creating unit (60). Thus, the PCS AC voltage fluctuations of the power conversion system are suppressed, when the self-contained run is made after lapse of a predetermined time period by changing the change switch (400) to the output side of a self-contained PWM command value creating unit (30). ® KIPO & WIPO 2009

These characteristics substantially improve the solubility of the poly(arylene ether) in the curable composition and allow the curable composition to be formed and used at or near room temperature. Composites formed by the process and circuit boards including the composites are also described.

Title: Method for processing silicon base material, article processed by the method, and processing apparatus
Inventor: WARABISAKO TERUNORI
IPC: H01L31/058
Filed: 2008-05-09
Abstract: In a state where a silicon base material (1) is used as an anode, a fine platinum member (2) is used as a cathode, and an electrolyte solution (4) is arranged between the anode and the cathode, anodic oxidation is performed in constant current mode under the conditions where porous formation mode and electrolytic polishing mode mixedly exist. The platinum member (2) is fitted in the silicon base material (1) with silicon elution, and processes such as hole making, cutting, single-side pressing are performed. Since the silicon base material can be processed at a room temperature with small energy, the crystal quality of the processing surface is not deteriorated. Thus, efficient and highly accurate processing can be performed without using a mechanical method, which consumes much material in conventional processes such as cutting of solar cell silicon base material, and without using laser whose energy unit cost is high, and furthermore, without leaving a crystal damage on a processed surface.

Title: Cemented carbide material and tool
Inventor: TSUNODA HIDEO
IPC: B23F21/16
Filed: 2008-07-28
Abstract: Cemented carbide alloys are a material having hardness and high toughness. Various trace elements are added in order to obtain these performances. One of the additives is vanadium carbide (VC). However, the incorporation thereof failed to evenly improve properties of a product because a raw material obtained by pulverizing the carbide has a large particle diameter. The carbide, which is one of raw materials for constituting a material for tools, e.g., a hob, was replaced with vanadium trioxide (V2O3), which is an oxide. Since the vanadium oxide is softer than vanadium carbide, it is easily reduced to fine particles in the step of mixing by means of a ball mill in raw-material preparation. Due to the effect of the vanadium trioxide evenly dispersed in the raw materials, the cemented carbide alloy obtained through sintering has an enhanced hardness.
