Filed: 1982-01-14
Abstract: PURPOSE:To etch at a high speed a doped polycrystalline Si without undercut under the condition that a cathode voltage drop is 30V or higher in such a mode that high density plasma is concentrated on the gap between N and S. CONSTITUTION:The reaction chamber is divided into an etching region 3 of a substance 8 and a high frequency region 15 of a magnet device 1 by a water cooling type cathode 4 to which a high frequency is applied and the region 15 is kept under the highly vacuumed condition for preventing discharge. At the upper surface of the magnet device 1, an S-pole permanent is surrounded by N- pole permanent magnets on a soft iron plate. When Cl2 is discharged, the discharge mode is classified into the mode a where the area on the gap 17 between N pole and S pole is dark and discharge 18 occurs at the periphery and the mode b where discharge is concentrated on the gap 17. In both discharge modes, etching rate and selectively are excellent but when the mode b is particularly selected, high density plasma is concentrated on the gap and etching is carried out at a cathode drop voltage of 30V or higher, especially of 50V or higher, anisotropic etching can be realized at a high speed with a little undercut and high reliability. This etching is very advantageous for microminiature fabrication.

Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To require no maintenance for a long time by arranging a lubricant containing polymer member in a slider, supplying lubricant to a rail via a contact face with a guide rail, and reducing a contact area as against a projection area to the rail. SOLUTION: A side seal 10 is installed on an end cap 2B end face in each end of a slider, and a lubricant containing polymer member 11 is put between a reinforcing plate 20 and the side seal 10 so as to be installed between them. The polymer member 11, which is made of a substance prepared by adding paraffin group mineral oil serving as lubricant to polyethylene consisting of low molecular weight polyethylene and super high molecular weight polyethylene, is molded by means of an injection molding machine. In the polymer member 11, a ratio of a contact area with a guide rail 1 is set within the predetermined range smaller than that of a projection area to the rail 1. In this way, a temperature increasing area due to frictional heat with the rail 1 is reduced and a lubricant discharge ratio is lowered, so that lubricant can be continuously supplied for a long time.  As a result, a maintenance free duration can be secured for a fixed period.

Title: Thermal cracking method for petroleum heavy oil
Inventor: SAKURAI MASAO
IPC: C10G9/20
Filed: 1981-01-16
Abstract: PURPOSE: To produce in a stable manner pitch that is enriched in a specific component and has excellent quality using a small-sized reactor, by transperring heated heavy oil supplied into the lowest part of the reactor into upper reaction regions in order under stirring though a central open part of the reactor to thermally crack the heavy oil.  
     CONSTITUTION: Raw heavy oil is heated to 450W520°C in a turbular heating furnace 3 and continously fed into the lowest part of the reactor 4. Rotation of a stirrer 11 causes the oil to be treated to rise through a central open part of the reactor. When the oil reaches the inner wall surface, it returns, transfers along the upper part of the reaction region 12, and then it rises and flows into the next reaction region. As the oil to be treated transfers upwards, it is gradually converted into pitch generating buffles with the progress of thermal cracking and polycondensation reactions. The desired reaction ratio of the oil is reached in the uppermost part of the reactor, and then the oil continuously flows out of the reactor into a cooling tank, in which it is cooled, e.g., to 350°C or lower and its thermal cracking reaction is stopped. Generated gases and steam are led into a fractionator 6 to be separated into cracked gas 13 and thermal cracked light oil 14. The transfer of the oil to be treated into the succeeding reaction region is made smooth by the buoyancy of the generated bubbles, so that the reaction can progress without any reverse flow.

Title: Power amplifier
Inventor: HORI FUMIO
IPC: H03F3/21
Filed: 1982-01-14
Abstract: PURPOSE:To attain an audio amplifier with less distortion, by selecting a larger voltage out of a voltage of a bias power supply and an output voltage of a peak rectifier circuit and applying the resulting voltage to the base of the 2nd transistor (TR). CONSTITUTION:When an input signal is positive and smaller than the 1st power supply voltage V1, a current flows to a load RL in the path of the 1st power supply Vcc1-diode D1-1st TRQ1-load. When the input signal is larger than a voltage subtracting a voltage of a Zener diode D2 from the VL, a voltage sum between the voltage of the D2 and the output voltage e0 is applied to the base of the 2nd TRQ2 via a diode D4. Thus, the emitter potential of the Q2 is higher than the VL and the D1 is turned off and the Q1 is turned on. The collector voltage Vc of the Q1 is charged to a capacitor C through a rectifier diode D3. When the input signal is smaller, the e0 is smaller and the D4 is turned off and the voltage charged in the C is applied to the base of the Q2 through a diode D5, the C is discharged and the collector voltage of the Q1 is changed with the time constant until the voltage across C reaches the VL.

Title: Preparation of oxide superconducting thin film
Inventor: OGIWARA MITSUHIKO
IPC: H01L39/24
Filed: 1992-01-13
Abstract: PURPOSE:To stabilize the molecular beam intensity in a molecular beam epitaxial method and obtain a superconducting thin film of excellent quality with good reproducibility by previously heating a raw material rubidium oxide and removing impurities and gases. CONSTITUTION:Commercially available Rb2O is placed in a crucible, set in a Knudsen cell, kept in a high vacuum state and heated. The Rb2O initially changes the color gradually from brown or green, turns black, starts melting and soon begins boiling to violently release gases. When the temperature is further increased, it gradually turns a color close to white and remains only in the bottom. When the boiling is continued at 450-480 deg.C, the bubbling stops and the Rb2O changes into a liquid state. When the release of the gases stops, the vacuum degree is improved. After allowing the Rb2O to stand for about 10min, the temperature is lowered to change the state into a solid. The resultant purified Rb2O, Bi and Ba are used as raw materials to prepare a Bi-Ba-Rb-O type oxide superconducting thin film according to a molecular beam epitaxial method. Thereby, the objective thin film is stably formed and the critical temperature of the prepared superconductor is about 25K. The preparation can be carried out with good reproducibility.
