Abstract: PROBLEM TO BE SOLVED: To lessen the possibility of the generation of sparks and to improve safety by forming a bearing, an atomizing head, a hollow shaft for mounting the atomizing head and a coating material supply pipe of nonconductive materials and providing the front end of the coating material supply pipe with an electrode for high voltage impression. SOLUTION: A hollow shaft 3 for freely rotatably supporting an air bearing 2 by supplying the pressurized air from a rear part to the inner periphery of the bearing is rotationally driven at a high speed by an air motor 4 in the rear part. An atomizing head 5 of a bell type is mounted at the front end of the hollow shaft 3. The air bearing 2, the hollow shaft 3, the atomizing head 5 and the coating material supply pipe 6 are composed of the nonconductive materials.

Abstract: PURPOSE:To detect the loosening, breakage, or crack of bolt highly accurately by exerting electromagnetic vibration to the head part or the opposite end part of a bolt, detecting longitudinal vibration of the bolt, and then measuring resonance frequency based on a vibration signal detected. CONSTITUTION:A probe 1 is pressed, at the tip thereof, against the head part 18 or the other end part 19 of a bolt 3, a vibration transmission rod 9 is pushed in while resisting against the resiliency of a spring body 11, and a bobbin 5 is abutted, at the end thereof, on the head part 18 or the other end 19. Under that state, the vibration transmission rod 9 abuts, at the tip thereof, on an appropriate point of the bolt 3 positively under predetermined conditions and a predetermined resiliency functions, as bias, on a vibration detector 8. An exciting current I0 is then fed through a cable 12 to an electromagnetic coil 6 in order to exert longitudinal vibration to the shank 17 of the bolt 3, and a vibration signal V0 of the bolt 3 detected through the vibration detector 8 is delivered on a cable 16 to a control circuit. The control circuit takes out only longitudinal signal of the shank 17 from the signal V0 and detects resonance frequency thereof thus detecting tightness and crack of the bolt 3.

Title: Semiconductor device and its manufacturing method
Inventor: MOGAMI TORU
IPC: H01L29/78
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To try to decrease parasitic capacitance of gate electrodes and wirings. SOLUTION: A gate electrode 5 is formed, through a gate insulation film 4, on a device separation film oxide 2 formed on a silicon substrate 1. A lightly doped source-drain area 3a is formed by impurity doping (a). A silicon oxide film is frown by RF sputtering method with its wafer substrate biased low voltage (i.e., -10V). With this process, a considerably close film can be formed on the flat area, however on the rough area, a film with slit cavity is formed close to the side of the gate electrode because of poor step coverage. A heavily doped source-drain area 3b is formed by impurity doping (b). After an inlet layer insulation film 7 is formed (c) and a contact hole is opened (d), the Al wiring 8 is firmed (d).

Abstract: PURPOSE:To attain efficient Haar transformation with a single speed clock by calculating simultaneously coefficients to be calculated for high and low order sides in a stage that part of picture data is inputted and executing the calculation in specific process thereafter so as to use required minimum number of adders and subtractors. CONSTITUTION:When an 8-picture element picture data block is Haar- transformed through three stages of divisions, outputs of registers 1c-a are respectively D0-D2 at a point of time of a time slot 0, then data selectors 2a, 2b select an input of a terminal (a) and provides an output. Then picture elements D0, D1 are inputted to an adder 3 and a subtractor 4 and a low-order coefficient is stored in a register 5a from the adder 3 and a high-order coefficient is outputted from the subtractor 4. While the picture data are being received, the fetched picture data and the stored low-order coefficient are used to calculate a coefficient whose calculation is available repetitively. No calculation is made in a final slot 7 and the low-order coefficient stored in the register 5 is outputted.

Abstract: PURPOSE:To measure the overlapping deviation even after a wafer is coated with a resist thereon by measuring the overlapped deviation from the positional displacement of light beams of the reflecting lights having wavelengths of different absorptance to said resist. CONSTITUTION:The light from an HeCd laser source 1 forms an image before an objective lens 7. At this time, the position on an optical axis of a relay lens 5 is changed to adjust the distance from the lens 7 to a focal position on a resist mark of a sample 8. Moreover, a focal position of an optical system of an Ar laser source 11 is adjusted by the position of a relay lens 15 on an optical path, so that the focus is met on a reference mark on the sample 8. Each reflecting light from the sample 8 is incident upon photoreceptors 10, 17 via the lens 7, and each output signal from the photoreceptors 10, 17 is taken into a computer 19, where the overlapping deviation of each beam is calculated. The calculating result is fed to a printer 20.

Filed: 1985-08-20
Abstract: PURPOSE:To stop or suppress scattering of toner by composing at least the surface part of a toner carrier by using silicone rubber with which a <=60vol% filler is mixed. CONSTITUTION:When the rotating speed of a photosensitive body 6 is fast like a fast copying machine, toner on a roller 4 leaves a developing roller 4 and scatters owing to a centrifugal force operating on the toner on the roller 4 and an air flow generated by the rotation of the roller 4. For the purpose of eliminating it, the developing roller 4 is composed of a core material 4a made of a conductive material such as metal and a silicone rubber layer 4b fixed around it and the <=60vol%, preferably, <=50vol% filler is mixed with the silicone rubber. Thus, at least the surface part of the developing roller is made of silicone rubber which has enough stickiness to hole the toner by itself, so that the toner is prevented securely from scattering.

Abstract: PURPOSE:To obtain clear images having high density without generating wrinkles on a transfer record medium at a low cost by providing on a transparent substrate a mold release agent layer having a thickness of 0.01-2mum formed out of mold release agent of polyester denatured silicone resin. CONSTITUTION:An image receiving medium is constituted of a mold release agent layer B containing mold release agent as a principal component layered on an image receiving substrate A having dyeing property. Heat sublimation dye sublimates and diffuses from a dyeing transfer layer 4 of a sublimation transfer record medium due to heat of a thermal head 1, and is transferred to the image receiving medium, so that the sublimation dye diffuses in the image receiving substrate A for dyeing. The transparent substrate A of the image receiving medium is made of a transparent film having high dyeing property and heat resistance of the heat sublimating dye, whose crystallinity is lowered by solvent treatment. For the mold release agent forming the mold release agent layer B, polyester denatured silicone resin, with which friction coefficient of the transfer record medium and the image receiving medium is appropriate and wrinkles do not occur on the transfer record medium at recording, is used. The transparent substrate A is coated with solvent for the mold release agent layer and dried so as to form a mold release agent layer B having a thickness of 0.01-2mum.

IPC: H04L9/18
Filed: 1993-06-30
Abstract: PURPOSE: To provide a device for decoding a variable length code with less storage capacity. CONSTITUTION: The tree of variable length code is arranged in the (k) node display and thereafter, the arranged tree is decoded. The (k) node indicates the binary leaf of the code length for any specified number and is the node of the tree, for not including the (k) node in a path to a route. By expressing a decoding problem by the arranged tree shape, the decoding problem is divided into segments, and thus the variable length code is decoded with less ROM memory amount. In an application for using plural ROMs 100, 200 and 300 instead of a single ROM, the individual ROM becomes of a word number which is less than a conventional ROM.
