Title: Gas laser tube
Inventor: TAKIZAWA HIROSHI
IPC: H01S3/038
Filed: 1980-10-07
Abstract: PURPOSE:To obtain a gas laser tube with higher reliability, by a method wherein one of a cathode is enlarged outward for obtaining resilience, and the cathode is made so as not to be subjected to a slide shift by pressing a glass vessel with the resilient force. CONSTITUTION:A cylindrical cathode 9 is equal to a cylindrical vessel in their outer diameters practically, and contacts with the inner surface of the vessel without shifting in the radial direction. The axial length of the cathode is much shorter than the internal axial length of the glass vessel, thus it is easy to be slided and shifted by the force from the outside. To suppress the shift described above, one end of the cathode is enlarged and a flare 91 is attached. The diameter of the flare part is slightly larger than the internal diameter of the glass vessel, therefore, it can not return to the original position because of the pressure pressing the tube wall of the flare when the cathode is inserted into the glass vessel for sealing the laser tube. Thus, a gal laser tube with high reliability is obtained.

Title: End breakage detector
Inventor: SAKO JUNICHI
IPC: B65H63/032
Filed: 1987-06-04
Abstract: PURPOSE:To carry out the always accurate detection of end breakage by providing a restricting means of elastic displacement on the opposite side to the elastically displacing side of a sensing plate while providing a closing body which permits the elastic displacement in the displacing direction while closing an action space. CONSTITUTION:When a yarn exists in the inserting part 13b of a sensing plate 13, the sensing plate is elastically displaced due to the resistance of the yarn or the tension of the yarn passing through the inserting part 13b. At this time, the sensing plate 13 is elastically displaced only in one direction of the action space S in a case body 11 due to an insulating layer 19. Hence, the damping time of the sensing plate can be reduced and, accompanying the elastic displacement of the sensing plate 13, only a necessary detection signal is outputted from a distortion detecting element 15. And, due to this detected signal, the detection of end breakage can be accurately carried out without causing erroneous operation.

Abstract: PURPOSE:To clearly and stably detect a color shade by using a color camera, using a diffusive light source for lighting, and making the color shade on a wafer imaged on the camera into binary. CONSTITUTION:A back sheet 5 is provided to image a profile on a wafer on a color camera 3. As the light source for lighting, for example, a face light source 2 having a diffusive plate in the front of a fluorescent lamp or a diffusive light source is used, and arranged around the lens 4 of the camera 3.

The image is made binary to three colors of red(R), green(G), and blue(B) by the control device of the camera 3, and the color of a color shade part is registered. The color shade is made binary in this way, whereby the magnitude of the area of the color shade can be quantitatively grasped, and the judging standard for color shade is clarified. Thus, the ambiguity in judgment by individual difference and the extension of the judging time are eliminated, and yield and quality can be improved.

Title: Magnetic top bearing device for vertical type rotor
Inventor: SHIMIZU FUKUZO
IPC: F16C32/04
Filed: 1986-06-18
Abstract: PURPOSE:To obtain strong damping forces to match a rotor body by permitting a permanent magnet to move freely in the horizontal direction and to be held centripetally, under the condition that a minute liquid film is provided for the magnet. CONSTITUTION:A permanent magnet 13 is held by a support member 14 capable of making centripetal action, such as a spring or the like. The permanent magnet 13, magnetized in polarity, restricts the position of a permanent magnet 2 in the radial direction, i.e. the position of the top end of a rotor body 1 in the radial direction, due to magnetic repulsion caused against a permanent magnet 2. Further, the support member 14 forms a minute liquid film in the horizontal direction, which produces a shear effect between the bottom face of the permanent magnet 13 and the inside bottom wall of a liquid bath 11. Therefore, said magnet is held in such that a minute clearance 15 may exist to make it possible to obtain strong damping forces to match the rotor body 1.

IPC: G06F3/06
Filed: 1990-05-31
Abstract: PURPOSE:To efficiently evaluate the command overrun recovering processing of firmware by setting up a command overrun detecting point with the firmware. CONSTITUTION:If a command is not issued when the output 301 of a counter 30 is turned to '0', command ovrerun is generated. When an optional value less than the initial value of the counter 30 is set up in the register 40, virtual generation of command overrun is applied to a processor 10 at a point of time when command overrup is not normally generated. Thus, the command overrup recovery processing of the firmware can be efficiently evaluated.

Abstract: PURPOSE:To obtain an accurate profile of an impurity in a manufacturing process of an LSI by a method wherein defects and atoms to be diffused are formed on the surface of a crystal and the defects and the atoms are irradiated with an electron beam and are diffused into the crystal. CONSTITUTION:In order to obtain a high-accuracy impurity profile, high- concentration impurities to be diffused and lattice defects are generated on the surface of a crystal; the impurities and the lattice defects are formed to give a desired profile by using an electron beam 5.

Filed: 1995-06-08
Abstract: PURPOSE: To prevent the generation of a passing phenomenon by deviating write side and read side control signals more than their storage units and sepa rating respective operating addresses. CONSTITUTION: On the write side, data are written in a device 2H by 2H. In a -WE signal, only the specified part of a horizontal synchronizing signal during 1H is enabled but either the entire period or only the partial period of 1H is acceptable. Under this control, the value of a write side address counter changes like a write address W. Next, on the read side, a-RRST signal is inputted once for two times of-SYNC as well. Namely, the read side is reset once for two times similarly to the write side but when attention is paid on the phase relation of those reset signals, the phases are shifted for 1H on the write side and the read side. Under this control, the read side address changes like a read address R.

Title: Skin cataplasm sheet and adhesive sheet
Inventor: FUJII KIMIHIRO
IPC: A61K9/70
Filed: 1993-06-14
Abstract: PURPOSE:To obtain a skin cataplasm sheet excellent in usability and improved in the adhesive force between the sheet and tack agent, by providing a base sheet with a short fiber-incorporated primer layer followed by firmly laminating the primer layer with a tack agent layer. CONSTITUTION:Using, as a base sheet, a flexible vinyl chloride-based resin film 50-150mum thickness, one thereof is provided with (A) a primer layer containing 0.1-10wt.% of short fibers and consisting of a reaction product or mixture of a polyester resin having hydrophilic groups in the molecule and a polymerizable double bond-contg. monomer, followed by firmly laminating the primer layer with (B) a water-based tack agent layer by e.g. gravure coating method, thus obtaining the objective skin cataplasm sheet. Owing to the short fibers incorporated in the primer, unevennesses are developed on the surface of the primer sheet, expanding adhesive area through anchoring effect and raising the adhesive force between the base sheet and the tack agent. After this skin cataplasm sheet is used and peeled off the skin, nothing is left on the skin. This skin cataplasm sheet can also used in the form of a commerical product made up of a base sheet such as a protective sheet or electrical insulating tape and a tack agent layer.
