Title: Tool for polishing substrate
Inventor: WATANABE JUNJI
IPC: B24B37/12
Filed: 1985-02-22
Abstract: PURPOSE:To permit a semiconductor substrate and a crystal substrate to be flatly polished with pinpoint accuracy by forming textile layers through which a processing liquid can be percolated onto the flat surface of a polishing tool composed of a resin block thereby to increase the capability for capturing isolated grains on the flat surface. CONSTITUTION:A processing liquid 18 including isolated grains 17 dispersed therein is supplied between a substrate 12 and a polishing tool 11 and the tool 11 is relatively moved toward the left direction with respect to the substrate 12. Since a resin block is exposed as it is on the surface of V-shaped grooves 14, the processing liquid is prevented from percolating from their inclined surfaces 15 into the inside of the polishing tool 11 to produce a regular dynamic pressure in the V-shaped grooves 14. Thus, the substrate 12 is floated from the surface of the tool 11 to the position where the dynamic pressure and a processing pressure are balanced with each other so that the substrate 12 is held in a non-contact state. On the other hand, since textile layers 16 are exposed on flat portions 13, isolated grains 17 are liable to be captured by pores and among respective textiles and furthermore the processing liquid 18 is percolated thereto, the substrate 12 is polished by the collision of the substrate 12 with the isolated grains 17 which is caused by the flow of the processing liquid 18, and the chemical action of the processing liquid 18.

Title: Coating method
Inventor: SUZUKI MAMORU
IPC: B05D1/36
Filed: 1988-02-18
Abstract: PURPOSE:To prevent a lack of hiding from being produced between the coated films, by, in the case of coating the inner side of material to be coated with the same paint as that for the outer side thereof, coating in advance the inner side with other paint insoluble in said paint, and, thereafter, applying said paint thereon in wet-on-wet manner. CONSTITUTION:When the inner side of material to be coated is coated with the same paint as that for the outer side thereof, other paint insoluble in said paint is coated in advance, and, thereafter, the paint is applied thereto in wet- on-wet manner. In this manner, occurrence of vapor-wash is avoided, preventing a gap from being produced between the coated films. For example, in the case of coating the inner side of the door plate of a super-color car whose second coating and finishing have same color, at first, pretreating, such as washing and degreasing, is applied to a steel 1 of door, following which, after electrodeposition coat 2 is formed, epoxy-modified alkyd resin, for example, is applied as a first finish-coating film 3. And, while the coating film 3 is being held in a wet state, the same paint as that for the outer side, e.g., melamine alkyd, is applied thereto as a second finish-coating film 4 to be dried and baked thereon successively.

By so doing, conductive efficiency of injection career increases and amplification ratio of the current increases remarkably, base scanning time reduces in proportion to two times of base width and cut-off frequency increases remarkably.

Abstract: PURPOSE:To block transmission of vibration to the housing by fitting an oil- impregnated metal idly to the bearing cabin of the housing and forming a predetermined gap with respect to the bearing cabin thereby absorbing vibration produced at the bearing section through the gap. CONSTITUTION:An oil-impregnated metal 3 is fitted loosely through a predetermined gap to the bearing cabin 2 of the housing. An oil film layer A is formed between the fitted bearing metal 3 and the bearing cabin 2 in order to eliminate rattling. Since an oil film is formed in the gap, vibration produced between the shaft and the bearing metal can be absorbed.

Abstract: PURPOSE:To attain generation of a DCS signal in the case of file transfer. CONSTITUTION:A transmission command and a transfer type are entered from a transmission command section 3. When the transfer type indicates transmission of image information, negotiation of the usual image information transmission is implemented and a DCS signal is generated based on the result. On the other hand, when it is discriminated that the transfer type indicates file transfer, a data type discrimination section 17 discriminates a data type. Furthermore, when the data type discrimination section 17 discriminates that the transmission data type is a file, a storage value is read from a default storage section 18 and it is outputted to a DCS generating section 16. When the data type indicates image information, a parameter for commanding image information transmission is read from the data storage section 7 by the DCS generating section 16. The DCS generating section 16 generates a DCS signal based on the received data and sends the signal to a line via a communication section 9.

Title: Stopper holding device
Inventor: FUKUYAMA SHIGEKAZU
IPC: G11B17/028
Filed: 1987-02-19
Abstract: PURPOSE:To omit the adjustment of operation timing by executing handle locking operation even if a clamp cam handle is not completely clamped. CONSTITUTION:If a solenoid 1 is driven when the clamp cam shaft 10 is rotated and the position of a pin 10a fitted vertically to the shaft 10 is not yet reached to a locked position in spite of a clamped state, a stopper fitting 5 is abutted upon a pin 10a and the shaft 10 is not locked. However, a solenoid iron core 3 contracts a stopper spring 6 and completes operation. Although the rotation of the shaft 10 is not locked under said state, the stopper fitting 5 is moved by the restoration force of the contracted spring 6 and locks the shaft 10 by completely clamping the shaft 10 from said state or clamping the shaft again from the unclamped state. Consequently, it is unnecessary to adjust the positional accuracy of the stopper fitting 5 and the shaft pin 10a which may be lost due to the dispersion of size of parts and to adjust the operation timing of the solenoid.

When the target member is thin, only burners having small diameters are used to deposit the glass soot. When the target member is thick, burners having large diameters are switched on to deposit the glass soot. Thus, the porous glass base material for optical fiber can be produced with a high production yield.
