Title: Surface working of metal
Inventor: SERINO YOUICHI
IPC: B21D22/02
Filed: 1982-02-19
Abstract: PURPOSE:To obtain metallic surface that has stable coefficient of friction under oil lubrication by pressing the surface of metal that performs torque transmission with an uneven face of high hardness and then pressing with a flat face. CONSTITUTION:On the flat surface 1a of a material 1 for parts made of spheroidized annealed high carbon chrome bearing steel, emery paper 2 etc. having uneven face higher in hardness than the surface 1a of the metal is placed. Pressure is applied from above by a press etc. to give unevenness more than 10mu in depth to the surface of the material 1. Then, a flat face 3a of a pressing member 3 made of steel high in hardness is pressed against the uneven surface 1a to form flat parts 1b and scattering holes 1c. The depth of holes is more than 5mu. When this treated material 1 is used for a part in which torque transmission is performed by mutual contact of the surface of metal under oil lubrication, the oil film is cut by deep holes 1c and metallic surface becomes a state of boundary lubrication. Accordingly, stable coefficient of friction and large torque transmission effect are obtained.

Abstract: PURPOSE:To prevent an optical beam on a scan surface from being out of focus, by providing a varible focus mechanism, which adjusts the focus position in the position where the optical beam is made incident on a rotary polygonal mirror, on the optical path of the optical beam between a beam light source and the rotary polygonal mirror. CONSTITUTION:A variable focus mechanism 9 is provided on the optical path before the position where an optical beam is made incident on a rotary polygonal mirror 5. A scan start detector 10 is provided on the optical path for the scan start of the optical beam 2 reflected and deflected by the rotary polygonal mirror 5, and the detector 10 generates a detection signal each time when the optical beam 2 passes, and this detection signal is sent to a control circuit 11 which controls the variable focus mechanism 9 to control the variable focus mechanism 9 synchronously with rotation of the rotary polygonal mirror 5. Thus, the optical beam can be always converged on the scan surface even if the reflecting surface of the rotary polygonal mirror is switched in accordance with rotation to change the reflection position of the optical beam. Consequently, the surface fall or the axial deflection of the rotary polygonal mirror is compensated with a high precision by an anamorphic optical system even if they occur, and the optical beam on the scan surface is prevented from being out of focus.

Title: Chemical-mechanical polishing method for forming embedded-type and protruding-type tungsten plug
IPC: H01L21/304
Filed: 1993-01-22
Abstract: PURPOSE: To provide a manufacturing method for a plug which is composed of a conductive material such as tungsten, more uniform than the conventional one, and free from recesses. CONSTITUTION: An insulating layer 10 is formed, on which a metal layer 14 is stacked. While a polishing pad is rotated with respect to a wafer surface, a metal over the entire wafer surface is eliminated by using slurry acting on the metal. By the chemical action and the action of a fiber component, the metal in a contact aperture 16 is recessed. In the next process, the insulating material 10 is eliminated from the periphery of a metal 14, by using a slurry containing acid or base which acts selectively on the insulating material. In this case, in order to polish the surface, abrasive material is contained in the slurry, and the height of metal is made equal to the surface of the insulating layer. The elimination of insulating material is continued until a plug protrudes slightly.

Abstract: PURPOSE:To obtain stable transfer and sepn. irrespectively of the condition of an original by detecting the density of the image formed on a photosensitive drum or the density of the original and controlling the voltage on one or both of a transfer charger and a sepn. charger. CONSTITUTION:A photosensitive drum 2 which is electrostatically charged by an electrostatic charger 1 is exposed through a slit 3 and the image thereon is developed to a sensible image by a developing device. The transfer paper fed from rollers 5, 5' contacts the sensible image surface on the drum 2 and is subjected to transfer with a transfer charger 6 then to destaticization with a sepn. charger 7. A reflection type photoelectric sensor 17 which detects the amt. of the toner adhered on the sensible image surface is attached to a developing device 4 in the lower part thereon on the downstream side with respect to the rotating direction of the drum 2. The output from the sensor 17 is inputted to a control circuit 20, and is supplied to an arithmetic circuit 23 after amplification 21 and integration 22. The circuit 23 calculates said output in such a way that the density of the image and the sepn. voltage are inversely proportional to each other and that the density of the image and the transfer voltage are directly proportional to each other. The voltages for the chargers 6, 7 are thus set optimum. The stable transfer and sepn. are made possible irrespectively of the original condition in the above-mentioned way.
