Filed: 1983-07-27
Abstract: PURPOSE:To detect the completion of etching with high accuracy by magnifying a striped pattern before and after an etching and binary-coding the pattern in the picture signal processing of the surface of a wafer using a TV camera. CONSTITUTION:A grounded upper electrode 2 and a lower electrode 3 connected to a high-frequency power supply 5 are arranged oppositely in an etching treating chamber 1, and a wafer to be etched 4 is placed on the lower electrode 3. Transparent glass 6 is fitted to the ceiling of the treating chamber 1, beams from a light source 13 for projecting beams are projected to the transparent glass through a semi-light transmitting mirror 16, and the contrast of a striped pattern by ion radicals generated in the wafer 4 is magnified by an observation system 10, and observed by using a TV camera 8. Accordingly, the threshold V1 at a level of the recognition-starting of the striped pattern 22 generated in the wafer 4 and a level V2 of an end-point detection are compared with each other, and the completion of etching is decided when these values are kept within the predetermined values.

Title: Burner
Inventor: SHIMIZU TERUSHI
IPC: F23D14/74
Filed: 1980-09-29
Abstract: PURPOSE: To increase te heating efficiency of a burner, by a method wherein a gas blow-off slit is provided to a blower tube to control the ratio of the air and the form of a flame in a burner which sucks the air for combustion by the negative pressure.  
     CONSTITUTION: The thin layer of gas fuel, jetted out of a gas blow-off slit 15 in high velocity, flows upward by the Coanda effect along the inside of a tube body 6 located in the position upper than the gas blow-off slit 15, while inducing the surrounding air into a flow. The gas fuel and the above-mentioned air being induced, used for the primary air, are mixed up together in a blow-off part 14, and ejected from an opening 16 to a furnace 4 to form a flame. The ratio of the air to a burner 3 can precisely be controlled, because the volume of the primary air, being induced into the gas fuel which is jetted from a gas blow-off slit 15, is proportional to the fed amount of gas fuel. In addition, the length of a flame can also be controlled by moving a blow-off body 10. As a result, the heating efficiency of a heating furnace 1 can be increased.

IPC: E04C2/20
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To obtain pure woody texture having excellent water resistance without using thick woody material by laminating a woody veneer on resin- impregnated titanium paper surface positioned on a resin-impregnated paper layer. SOLUTION: A building material A is composed of low-cost phenolic resin- impregnated paper 1 excluding the surface of a resin-impregnated paper layer 4 composing a base. The phenolic resin-impregnated paper 1 has a tendency to change color to black through deterioration with age, which may discolor (i.e., color-migrate) surface color of a woody veneer 5 on the surface of the building material A having woody appearance. To prevent this, resin- impregnated titanic paper 3, having high opacifying properties, is provided on the surface of the resin-impregnated paper layer 4. Thereby, discoloration with age of the phenolic resin-impregnated paper 1 is not affect the woody veneer 5. By using melamine resin having excellent weathering characteristics, discoloration of the resin-impregnated titanic paper 3 is prevented, which securely prevent color migration to the woody veneer 5.

Filed: 1986-06-12
Abstract: PURPOSE:To preferably selectively deposit a W without abnormal Si etching by cleaning the surface of a substrate by optical etching in case of selectively depositing a metal on the substrate by a CVD method. CONSTITUTION:After a thermal oxide film 2 is deposited on an Si substrate 1, the film 2 is etched to form a contact hole 3. At this time, a natural oxide film 4 is formed in the hole 3.

Title: Catalytic material and exhaust gas cleaning device using this catalytic material
Inventor: SUZUKI TADAMI
IPC: B01J23/40
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To reduce the heat capacity and improve the temperature-rising property and oxidation/decomposition performance and thereby lower odor by winding an electrically insulating plain plate and a corrugated beltlike heater alternately laminated to structure a heater for supplying heat through energizing the beltlike heater and forming a catalytic layer on the surface of the heater. SOLUTION: A cylindrical heater is obtained by corrugating a beltlike heat- resistant steel and laminating each one piece of a beltlike heater 1 with an electrode terminal fitted to both ends and an insulating plain plate 2 as layers and further, winding the heater 1 and plate 2. In this case, since the corrugated beltlike heater 1 is insulated by the insulating plain plate 2, the coiled laminated layers are not shortcircuited but voltage is applied to both electrodes only in the winding direction and thus a sufficient resistance value for generating heat is secured. After that, an undercoat layer 4 is formed on the surface of the heater 1 and a catalytic layer 5 of a noble metal such as platinum or palladium is formed on the surface of the undercoat layer 4. The undercoat layer 4 is formed of a sintered oxide containing aluminum, cerium barium.

Abstract: PURPOSE:To enable the sepn. and control of the light emission outputs of respective light emitting points by providing plural wavelength selective filters and plural light receiving elements in such a manner that the filters are opposed to the respective light emission points and providing feedback control systems to the light emission points as well. CONSTITUTION:A beam 12a for recording and a beam 12b for checking and reproducing from the light emission points 11a, 11b of a semiconductor laser array 1 are partly emitted to the light emitting element 20a, 20b side.

IPC: G01R33/389
Filed: 1994-06-20
Abstract: PURPOSE:To locally decrease gradient magnetic fields generated by a first gradient magnetic field coil by forming this first gradient magnetic field coil as a coil fixed to a magnet and constituting a second gradient magnetic field coil so as to nearly negate the gradient magnetic fields generated by the first gradient magnetic field coil in the specific region of an object to be inspected. CONSTITUTION:The output of the high-frequency pulse generator of an MRI apparatus is amplified by a high-frequency power amplifier to excite the coil 4. The signal received by the coil 4 is subjected to A/D conversion by an A/D converter and is then converted to an image by a signal processing system. This image is displayed by a display device. The small-sized gradient magnetic field coil 22 driven by a current amplifier 23 is installed in addition to the large-sized gradient magnetic field coil 21. The gradient magnetic field coil 22 is so operated as to negate the magnetic field generated by the gradient magnetic field coil 21 only in the specific section of the object to be inspected. As a result, the gradient magnetic fields exclusive of the photographing section are decreased and the uncomfortable feel acting on the object to be inspected is lowered. Photographing is thus executed with excellent safety.
