Abstract: PURPOSE:To facilitate both assembling and disassembling operations by inserting a pivoting rod of a butterfly valve into a cut groove of a half valve box on one side, while fitting a projecting piece of a half valve box on the other in the cut groove, and assembling an exhaust valve by way of joining both these boxes together through a connecting means. CONSTITUTION:This exhaust valve A consists of two opposed half valve boxes 1, 1 and a butterfly valve 2, and the assembly between these two half valve boxes 1, 1 and the butterfly valve 2 takes place in the flowing procedures that a pivoting rod 16 of the butterfly valve 2 is inserted intop a cut groove 10 of the half valve box 1 on one side and a valve plate 15 into an air port 8, respectively, and a projecting piece 11 of the half valve box 1 on the other is fitted in the cut groove 10. When this fitting is over, a semicircular notch part 9 at a tip of the cut groove 10 and another semicircular notch part 12 at a tip of the projecting piece 11 are opposed to each other, thus there is produced an almost true round cylinder hole pivotally supporting the pivoting rod 16, and positioning of this rod 16 is completed. An assembly of the exhaust valve is brought to completion by bolting it via bolt holes 6 of first flanges 4, 4.

Title: Measuring method by shape measuring apparatus
Inventor: AOYAMA BUNJI
IPC: G01B21/20
Filed: 1989-09-29
Abstract: PURPOSE:To obtain correct measuring data by selecting measurement data when a stylus is in one of a first and a second inclined areas where the stylus can move in an energizing direction or a direction reverse to the energizing direction, and mutually complementing the measurement data for the two areas. CONSTITUTION:A first area is where a stylus 11 descends corresponding to the surface state of an object W to be measured, while a second area is where the stylus 11 rises along the surface state of the object W. A core 18 of a differ ential transformer 17 is connected to a fixed arm 14, so that an output propor tional to the movement in the Z axis perpendicular to the stylus 11 is obtained from the transformer 17. Therefore, a Z axis detecting part 19 is constituted by the transformer 17. Moreover, an X axis detecting part 25 is formed by a rotary encoder 24. When the stylus 11 is moved in a withdrawing direction, the measuring data of the detecting part 25 is increased. On the other hand, when the stylus 11 is moved in an energizing direction, the measuring data of the detecting part 18 is decreased. Accordingly, if the stylus 11 is moved in two directions, i.e., withdrawing and energizing directions opposite to each other to measure the data, only the measuring data in the area where the stylus 11 is lowered can be used as the measuring data of a V groove 40.

Abstract: PURPOSE:To improve the yield of products due to misalignment or, etc., and obtain precise, uniform image displays and optical signals by integrally forming a modulating electrode and an electron emission element on a board and differentiating the film thickness of an insulation layer under an electron emission section from that in other areas. CONSTITUTION:A resist is formed on an insulating board 1. After Ti as under- coating material and Ni as modulating electrode material evaporated all over, a modulating electrode pattern 2 is formed. A resist pattern is formed to make a modulating electrode layer thin in part. Ni at the lower part of electron emission elements 3, 4 is given about 4000Angstrom  etching. The resist is peeled to obtain the desired modulating electrode pattern 2. SiO2 for an insulation layer 5 is given mask-deposition as necessary. After pre-protecting the area where SiO2 is not laminated, the surface of SiO2 is made flat using ion mealing. An element electrode pattern 3 of SCE is formed above the electrode 2. Cr is evaporated all over to remove only Cr near the electron emission section 4. Organic palladium as emission material is formed all over. Patterning Cr is etched out.

Title: Semiconductor device
Inventor: KOGA JUNJI
IPC: H01L29/66
Filed: 1991-10-04
Abstract: PURPOSE:To achieve a three-terminal diode by changing the entire junction plane of impurity regions which constitute a diode to a depletion layer using a third electrode, so that the modulation effect of junction currents is significantly increased. CONSTITUTION:A p-type high concentration impurity region 12 and an n-type high concentration impurity region 13 are formed adjacent to each other on a silicon substrate 11. A control electrode 15 is formed on the surface of the p-type high concentration impurity region 12 with a silicon oxide dielectric film 14 sandwiched therebetween. When a positive voltage is applied to the control electrode 15, a depletion layer develops over the surface, so that the depletion layer of a tunnel junction is extended, and hence a tunnel current is decreased. Adversely, when a negative voltage is applied to the control electrode, a plurality of carriers are stored along the surface, whereby a carrier concentration is effectively increased, and then the depletion layer is expanded and contracted. Accordingly, tunnel current is increased. The variation of the applied to the control electrode 15 enables the tunnel current to be set to a desired value, whereby a threeterminal type tunnel effect element can be achieved.

Title: Planar element of high breakdown strength
Inventor: WATANABE KIMINORI
IPC: H01L29/73
Filed: 1990-09-28
Abstract: PURPOSE:To miniaturize a planar element of high breakdown strength, by so forming a highly resistive film as to be in contact with one end of a polycrystalline silicon film so arranged as to be simultaneously in contact with a source layer and a base layer, and one end of a polycrystalline silicon film so arranged as to be in contact with a drain layer. CONSTITUTION:When a voltage is applied across a source and a drain, the potential of a semiinsulative polycrystalline silicon film 23 is excellently fixed, in such a manner that the drain side is fixed to a drain potential via a p<+> type polycrystalline silicon film 31, and the source side is fixed to a source potential via an n<+> type poly-crystalline silicon film 32. A very weak current flows in the semiinsulative polycrystalline silicon film 23 so as to uniformly distribute all over the element, and uniform potential gradient is generated in the lateral direction. As a result, electric field concentration inside the element is relieved, and a high voltage is obtained. The length of a gate electrode 18 can be an irreducible minimum, and the element length is reduced, thereby the element is miniaturized, and the element length is shortened, so that the resistance in the lateral direction is reduced and the ON resistance is lowered.
