Title: Polishing device and polishing method
Inventor: YAMAUCHI TOMOHITO
IPC: B24B21/00
Filed: 1988-06-30
Abstract: PURPOSE:To simply and efficiently polish and finish the surface of a body to be polished into a smooth, continuous, aspherical surface by pressing the surface of the body being polished on a travelling polishing tape with the body tilted and moved, and continuously changing contact pressure between the surfaces to be polished and the polishing tape. CONSTITUTION:With a holding mechanism 7 holding a body (magnetic head) 1 being tilted by an oscillation mechanism 14, the surfaces (peripheral edge part) 2a, 2b of the body 1 to be polished are pressed on a polishing tape 19 travelling at constant speed. By the pressing operation, a pad 26 located close to the polishing tape 19 and its rear face is depressed against an elastic reaction force of a spring 25 supporting the pad 26, and contact pressure generated between the surfaces 2a, 2b to the polished and the polishing tape 19 is continuously changed in accordance with the tilt of the surfaces 2a, 2b to be polished. As a result, the surfaces 2a, 2b to be polished can be polished and finished into a smooth, continuous, aspherical surface.

Title: Crystal growth
Inventor: TAKIGUCHI TORU
IPC: H01L21/208
Filed: 1989-06-27
Abstract: PURPOSE:To lessen the quantity ot a remaining melt on the surface of a crystal and prevent the decrease of a crystal effective area and then, render the surface of the crystal flatter as well by making an epitaxial crystal come into contact with the melt having a melting point lower than that of the melt for growth immediately after performing a crystal growth. CONSTITUTION:Immediately after performing a crystal growth, an epitaxial crystal is allowed to come into contact with a melt 9 having a melting point lower than that of a melt 8 for growth in a short while. Immediately after performing the crystal growth, in this way, when a crystal having a remaining melt on its surface is allowed to come into contact with the melt having a melting point lower than that of the melt 8 in a short while, the melt 9 having low melting point takes in the remaining melt. Its viscosity is so low that sweeping of the melt up is easily performed. Further, if time required for making the crystal come into contact with the melt 9 having a lower melting point is regulated, the surface layer of grown crystal is melted in the melt. This lessens the quantity of the remaining melt on the surface of a crystal and increases a crystal effective area as well and them, renders the surface of the crystal flatter.

Title: Method and apparatus for drying wood
Inventor: SUZUKI MAMORU
IPC: B27K5/00
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a method for drying wood which can reduce drying costs, an apparatus for the method, and an apparatus for drying wood which can reduce the construction costs of a drying chamber. SOLUTION: A drying chamber is divided into a front part treatment chamber 2 and a rear part treatment chamber 3. In the chamber 2, the temperature is increased to a necessary temperature by a heat generator to conduct temperature elevation and drying treatment. In the chamber 3, the heat discharged from the chamber 2 is used as a heat source to conduct moisture conditioning and cooling treatment. When the half of a whole drying treatment process is finished, wood treated in the chamber 2 is transferred to the chamber 3. By supplying a heat source used in the chamber 2 to the chamber 3 to be recycled, energy consumption can be decreased to reduce drying costs. The chamber 2 requires structure bearable to high temperatures and high humidity, but the chamber 3 is of a structure bearable to rather mild conditions of low to intermediate temperature so that the construction costs of the drying chamber can be reduced.

Filed: 1985-07-26
Abstract: PURPOSE:To generate torque equal to that of a DC motor by controlling a synchronous motor in a sine wave PWM manner by presetting the position of a rotor of the synchronous motor to a counter as an absolute value. CONSTITUTION:A pulse coder 119 outputs detecting pulses at every predetermined angle of rotation, and outputs one revolution origin detecting pulses.

Abstract: PURPOSE:To prevent useless ignition by providing an intake air pressure detecting means, ignition pulse output means and ignitable signal output means while furthermore providing the means for producing an ignition signal based on the product of ignitable signal and ignition pulse signal. CONSTITUTION:A negative pressure sensor 1 arranged in an intake gas tube between a carburetor 11 and an intake port will produce an air pressure detection signal which is removed of noise through shaping circuit 2 to produce an air pressure detection pulse signal. While a pulse generator 3 in crank case 14 will produce an ignition pulse signal and a shaping circuit 4 will produce a reset signal and a shaped operating ignition pulse signal correspondingly. AND gate 7 will produce a logical product of the output from a flipflop 5 receiving signals from the shaping circuits 2, 4 and the signal from operating circuit 6 and provide an ignition signal to the ignition circuit 8. Consequently, the compression stroke is separated from the exhaust stroke to execute ignition only under the compression stroke.
