Title: Composite metal plate excellent in vibration damping property
Inventor: FURUTA OSAMU
IPC: B32B15/01
Filed: 1987-08-20
Abstract: PURPOSE:To give excellent vibration damping property enough play even in high temperature region by a structure wherein at least two metal plates are empolyed as constitutional member and joined to each other under their laminated state by caulking. CONSTITUTION:A vibration damping composite metal plate has as its constitutional member at least two metal plates 1 and 2, which are joined to each other under their laminated state by caulking. By dividing the constitutional member into plate materials so as to join to each other, the joining members absorb their vibrational energy as frictional energy, resulting in allowing to give vibration damping effect enough play. As the metal plate, ferritic stainless steel, plain carbon steel, copper, aluminum or the like is exampled. As the caulking method for joining the laminated metal plates to each other, the laminated metal plates 1 and 2 are, for example, blanked with a punch or the like and the developed burrs 21 are bent so as to fit channel-shaped joining member to the peripheral part of the plate at proper positions. Thus, a composite metal plate, the temperature dependence of the vibration damping characteristics of which is very small and which also and simultaneously has the heat resistance allowing to sufficiently withstand the use even in the high temperature region such as 400-600 deg.C, can be obtained.

Title: Microprogram controller
Inventor: SATO SHINJI
IPC: G06F9/22
Filed: 1984-10-03
Abstract: PURPOSE:To decrease the stopping frequency of a microprogram controller owing to a chip fault by storing a microcommand equivalent to a word into plural chips with a memory which uses plural memory chips to store micro programs. CONSTITUTION:A microprogram storing memory 10 consists of plural memory chips, and each chip consists of an address and four bits. A microcommand equivalent to a word is decentralized and stored to plural chips every bit. Then the read data equivalent to four words designated by an address signal 22 are stored to buffer registers 15-18. The contents of registers 15-17 are read out successively and checked by an error detection/correction circuit 20. Then a bit error if detected is corrected and outputted. In case the correction of the bit error is impossible, the operation of a program is discontinued. In this case, however, the errors produced in a word are equal to a bit at mose. Thus the correction of the error is possible. This decreases the stopping frequency of a microprogram.

Abstract: PURPOSE:To compensate a shift from an fTHETA characteristic due to a lens constituted of a symmetrical surface rotated around an optical axis effectively, to form a curve on an image surface properly and to scan a scanning surface without distortion by arranging an optical element forming a non-spherical surface on its section in a scanning direction on an image formation element. CONSTITUTION:A beam radiated from a laser L is made incident upon a polarizer consisting of a polygon P or the like through lenses BE1, BE2 to be acted as beam expanders. An AOM element for turning on and off light and a cylindrical lens CY1 for converging the beam on the polygon P are arranged between the lenses BE1 and BE2 to reduce the interval between the lens BE2 and the polarizer. Light bent at its optical path by the polarizer is made incident upon the image formation element fTHETA constituted of the symmetrical surface rotated around the optical axis and a spot is formed on a photosensitive drum D through a cylindrical lens CY2. A lens CY2 arranged on the back of the fTHETA lens compensate the inclined angle of the polygon P together with the fTHETA lens. Consequently, the aberration of the distortion can be obtained by an extremely simple constitution without using specific compensating member.

Abstract: PROBLEM TO BE SOLVED: To facilitate the leading of an optical fiber by forming an intermediate layer consisting of a resin having a release property on an optical fiber and providing surface thereof with a coating layer consisting of a resin having specified elongation, thereby forming the optical fiber. SOLUTION: The outer periphery of the optical fiber 4 is provided with the intermediate layer 5 and is provided with the coating layer 6 thereon to form the coated optical fiber.

The release property is imparted to the surface of the intermediate layer 5 by the effect of this silicone resin. The resin used for the coating layer 6 preferably has elongation of 30 to 90%. If the elongation is below 30%, the elongation is insufficient at the time of stripping this coating layer 6 and, therefore, the pulling of the coating layer with large force is necessitated and burden is incurred upon the optical fiber 4. If the elongation exceeds 90%, the formation of a notch at the coating layer 6 by a tool, such as mechanical stripper, is difficult.
