Title: High breakdown strength semiconductor device
Inventor: NAKANO YASUKI
IPC: H01L27/04
Filed: 1993-03-18
Abstract: PURPOSE:To secure a high breakdown strength by causing a potential in the P-N junction of the main surface of a second guard ring region and the potential of a semi-insulating film in the same position to coincide with each other and by making the potential on a semiconductor film higher than that of a semiconductor surface on P-type semiconductor and the potential on the semi-insulating film lower than that of the semiconductor surface on N-type semiconductor. CONSTITUTION:In the relation between the surface potential of N-type silicon substrate 1 and potential on a semi-insulating film 8, the potential in the P-N junction of the main surface of a second guard ring region 3 and the potential of the semi-insulating film 8 in the same position as the P-N junction are caused to coincide with each other. Then, the potential on the semi-insulating film 8 is made higher than that of the surface of the N-type silicon substrate 1 on P-type layer side and the potential on the semi-insulating film 8 is made lower than that of the surface of the N-type silicon substrate 1 on N-type layer side so that both P- and N-sides have a field plate effect. Thus, stretching of depletion layers 10, 11 to the N-layer side can be suppressed and a high breakdown strength can be secured without raising the electrical resistivity of the N-type silicon substrate 1 and spreading the space between the guard ring region 2 and channel stopper 5.

Title: Pump with movable blades
Inventor: YAMADA MASAYUKI
IPC: F04D29/18
Filed: 1981-04-20
Abstract: PURPOSE:To adjust an impeller with a small blade adjusting force and ensure to hold it at the adjusted angle by providing a friction force variable means on a blade adjusting section so as to increase the friction force against the blade adjusting force while holding the blade angle and to decrease it while adjusting the blade angle. CONSTITUTION:When blades are to be adjusted, a boss oil pump is actuated and feeds the boss oil from the ground level to a stem bearing 29 through a boss oil feed pipe 60, a boss oil passage 58 in an adjusting rod 50, and a boss oil passage 56 in an impeller hub 41. Accordingly, the stem bearing 29 becomes a static pressure bearing, decreasing the friction force, thus an impeller 31 can be adjusted with a small adjusting force. When the blade angle is being held, the boss oil pump is stopped, and the stem bearing 29 resumes a normal sliding bearing, increasing the friction force, thus the impeller 31 can be held at the adjusted blade angle for sure. As a result, an oil pressure servo cylinder can be made small-sized and the overall pump can also be made compact.

Title: Method for checking pattern defect
Inventor: KAWASAKI FUMINORI
IPC: G03F1/00
Filed: 1988-03-11
Abstract: PURPOSE:To reduce the checking data quantity by segmenting the data on the patterns for repeating parts for each unit picture element for synthesization of these patterns to produce the check data when the repeating part of the same pattern is checked and collating said synthetic check data with a pattern to be checked for check of the pattern defects. CONSTITUTION:The size of a checking unit picture element 5 is set at 2mm in both X and Y directions in a checking state and 108 checking unit picture elements a1.1...a12.9 are successively checked. Then a unit repeating pattern 4 is processed so that the coincidence of patterns is secured among those unit picture elements since the pattern 4 has a size different from that of the picture element 5. Thus two patterns 4 are set in an area a1.1 of the element 5 X and 2/3 pieces of pattern 4 in the direction Y respectively in the area a1.1 of the element 5. In the same way, two patterns 4 are set in the direction X and 2/3 pieces of pattern 4 in the direction Y respectively in the area a2.1. Hereafter the patterns 4 are processed and arrayed so that the coincidence of sizes and patterns are secured for each element 5. Thus the checking data quantity can be extremely reduced.
