Filed: 1983-11-18
Abstract: PURPOSE:To achieve the reproduction of accurate width by enlarging the width of X-ray absorber pattern only by half out of focus at most on both sides of the width. CONSTITUTION:When the size of focus of an X-ray source is (d), a distance between a mask and an object to be irradiated is (s) and a distance between the X-ray source and said mask is D, and a half out of focus which is obtained from an equation delta=s.d/D is, the width of an X-ray absorber pattern is enlarged only by delta at most on both sides of the width. If the basic characteristics of resist such as gamma-value sensitivity and the value of soft X-ray intensity component in the area of delta is obtained accurately, or if the preset soft X-ray doze quantity is determined, the shape of resist pattern after development with soft X-ray irradiation can be obtained. Consequently, thinning is the resist pattern is determined to be the value of delta or under on both sides of that pattern. In other words, preset of the resist pattern width having an arbitrary value of delta or under is possible and if the preset value is determined, the enlarging quantity on both sides of the X-ray absorber pattern width can be determined to be that value.

Title: Scroll type compressor
Inventor: KIKUCHI KAZUTO
IPC: F04C29/02
Filed: 1989-08-25
Abstract: PURPOSE:To ensure the sufficient lubrication of a slide surface between a surrounding wall and a plate body, and prevent the seizure thereof by providing a main shaft with a lubrication pump for feeding lubricating oil to a lubrication passage, and an oil groove on the aforesaid surface for continuity to a communication passage. CONSTITUTION:When a main shaft 50 rotates, a drive pin 52 provided at one end thereof gives eccentric motion. This eccentric motion is transmitted to a movable scroll member 20 via the drive pin 52 and a boss part 23. As a result, the movable scroll member gives motion along an circular orbit. In this case, lubricating oil in an oil chamber is subjected to a centrifugal force due to the aforesaid circular orbit motion. Due to the centrifugal force, the lubricating oil flows into a communication passage and then reaches a slide surface between the surrounding wall of the first plate body 11 and the second plate body 21. Upon arrival at the slide surface, the lubricating oil spreads all over the slide surface via an oil groove. According to the aforesaid construction, the slide surface can be sufficiently lubricated and the seizure thereof can be prevented.

The pressure generation member 12 is of a center beam structure measuring 2mm in the longitudinal direction and 0.2mm in the width. In addition, the member 12 is composed of 'A' part which is about half as long as the beam in its longitudinal direction and 'B' parts at both ends having a reversed structural relationship in the thickness direction. If a voltage is applied, a mutually reversed moment generates in the A part and the B part and these parts become displaced with a curvature in a mutually opposite direction. Thus the pressure generation member with a center beam structure 12 generates a displacement efficiently and easily.

Abstract: PURPOSE:To eliminate a misoperation by a human being and to eliminate the effect of high-order reflection by sensing a vehicle in the combination of a vehicle reflection wave and a road reflection wave. CONSTITUTION:When the vehicle is out of a vehicle sensible area R, the gain of a second gain variable amplifying circuit 18 is at a second level during a vehicle gate period, and at a first level (the first level>the second level) during the period other than the vehicle gate. Thus, the road reflection wave S2 of 16L, which is an eight-times of a threshold 2L, is inputted to a threshold circuit 20. Next, when the vehicle enters up to the 1/2 of an area T, the level during the period of the vehicle gate of the circuit 18 is at the second level, and the gain level during the period of the road gate is at the first level. Consequently, the gain level of the road reflection wave becomes 8L, and that of the vehicle reflection wave becomes 4L. Next when the vehicle enters upto the 7/8 of the area R, the gain level of the road reflection wave becomes 2L, and that of the vehicle reflection wave becomes 7L, and the condition immediately before the vehicle sensing is obtained, and next, both the gain levels become 1L and 14L, and the value immediately after the vehicle sensing is obtained.
