摘要:
A method of making pattern data of a photomask pattern includes: the processes of adding, to each of first cells, information of the first cell higher than the first cell on the basis of a hierarchical structure; selecting, from the first cells included in one level of the hierarchical structure, the first cell identical to one of the first cells included in a level higher than the one level and the first cell placed inside two or more of the first cells included in a level immediately higher than the one level, and forming a cell group with the selected first cells; making pattern data of the first cells not included in the cell group in consideration of the optical proximity effect and forming a fourth cell group with second cells including the pattern data; and replacing the first cells with the corresponding second cells in input data.

An image forming apparatus includes a high-voltage power supply having a piezoelectric transformer. The power supply includes a positive output voltage generation circuit and a negative output voltage generation circuit. Each of the positive output voltage generation circuit and the negative output voltage generation circuit includes a piezoelectric transformer, a piezoelectric transformer driving circuit, an output voltage detection circuit, and a drive control circuit for outputting a control signal for controlling the piezoelectric transformer driving circuit using a signal from the output voltage detection circuit and an output voltage setting signal for setting an output voltage. The positive output voltage generation circuit and the negative output voltage generation circuit are simultaneously turned on when the output polarity of the high-voltage power supply with a piezoelectric transformer is switched.
摘要:
A blow-by gas returning apparatus is arranged to allow blow-by gas leaking from a combustion chamber of an engine into a crank chamber to flow in an intake passage through a returning passage, and to regulate a flow rate of the blow-by gas by a PCV valve placed in the returning passage. A supercharger is placed in the intake passage. The PCV valve is adapted to change a position of the valve element by electromagnetic force to change a passage opening area. A check valve is placed integral with the PCV valve in the returning passage between the valve element of the PCV valve and the intake passage. The check valve is arranged to inhibit back-flow of the gas from the intake passage.
摘要:
A glass substrate for an information recording medium is manufactured by polishing the surface of a raw material glass plate. The polishing of the raw material glass plate is divided into a step for performing a first polishing process to roughly polish the surface of the raw material glass plate to be smooth and a step for performing a second polishing process to finely polish the surface of the roughly polished raw material glass plate to be smoother. The first polishing process uses a polishing pad made of a synthetic resin foam and slides the polishing pad on the raw material glass plate surface while supplying a polishing agent to roughly polish the surface. A pad dressing process is performed on the polishing pad before being used in the first polishing process. The pad dressing process polishes the surface of the polishing pad by sliding the polishing pad on a pad dresser including abrasive grains.

摘要:
An information recording medium glass substrate manufactured by polishing the surface of a raw material glass plate. The polishing is divided into two steps, a step for performing a first polishing process to roughly polish the surface of the raw material glass plate to be smooth and a step for performing a second polishing process to finely polish the surface of the roughly polished raw material glass plate to be smoother. The second polishing process, using a polishing pad made of foam, is divided into two stages, pre-polishing with a polishing agent including abrasive grains of cerium oxide and post-polishing with a polishing agent including abrasive grains of silicon oxide. A rinsing process is performed between the pre-polishing and the post-polishing to rinse the raw material glass plate after the pre-polishing with a washing liquid to wash away the abrasive grains collected in the polishing pad in pre-polishing during the rinsing process.
