Title: Production of metal extruding member
Inventor: FUJITA MAKOTO
IPC: B22F3/20
Filed: 1992-01-29
Abstract: PURPOSE:To easily produce a highly rigid metal extruding member by compressing flaky metal particles packed into a compacting die in a heated state and carrying out extrusion in the compression direction with an extruding die. CONSTITUTION:Flaky metal particles 1 such as Mg alloy chips are packed into the container 2 of an extruder and compressed at room temp. with a punch 3. The flaky metal particles 1 preferably have about >=10 ratio of the max. length to the thickness. The resulting precompact 11 is hot-pressed white heating with a heater 4 to form a compact 12 of the metal particles 1 oriented in a direction nearly perpendicular to the compression direction in an adhered state. An extruding die 5 is then inserted into the container 2 and the compact 12 is extruded by pressing in the compression direction with an extruding ram 6 to obtain an extruded member 13 of the Mg alloy, etc. When a mixture of the Mg alloy particles with other metal particles such as Al alloy particles is used as the metal particles 1, the quality of the resulting extruded member 13 can be improved.

Title: Lens driver
Inventor: HASHIMOTO AKIRA
IPC: G11B7/09
Filed: 1989-01-23
Abstract: PURPOSE:To eliminate the influence of the affecting force and to improve the controllability of a lens driver by using the affecting force produced by the change of the magnetic flux density distribution on the surface of a permanent magnet to hold the middle point set in the focus control direction of an objective lens drive system. CONSTITUTION:At least a pair of slot means 30a to 30b are provided on a fixed yoke means 6 opposite to the magnetic pole surface of a magnet means 5 set to a mobile holder means 2. As a result, the magnetic flux density distribution secured on the surface of the means 5 in the case the means 5 is displaced in a certain direction is approximately symmetrical to the magnetic flux density distribution secured on the surface of the means 5 in the case the means 5 is displaced in the opposite direction. Therefore the restoring force always affects the means 5 in the direction opposite to the displacing direction of the means 5. Thus the middle point of the means 2 can be held and the controllability is improved for a lens driver.

IPC: G03G15/20
Filed: 1995-01-31
Abstract: PURPOSE: To eliminate the variance of the fixing coefficient of a toner image with respect to a recording paper and to prevent the recording paper from wrinkling at a fixing time. CONSTITUTION: A compression spring 5 is made to intervene between both end parts of a pressure adjustment member 11 disposed along in the shaft direction of a pressure roller 4 and a bearing 3. The adjustment member 11 is freely turnably fitted to a pressure adjustment member shaft 13 in a state where the spring 5 can elongate and contract. The shaft 13 is disposed at such a position that the corresponding spring 5 is pressured by both ends of the adjustment member 11. Therefore, when the variance of a pair of springs 5 is found, the adjustment member 11 is turned around the shaft 13 as a center according to the variance. When this turning action is stopped, such a state where one of a pair of springs 5 contracts and the other thereof elongates is maintained.  As the result, even when the variance of a pair of springs 5 is found, the pressure force of the roller 4 in the shaft direction with respect to a heat roller 2 is balanced.

Title: Structure and method for adjusting degree of coupling of strip line filter
Inventor: ISHIKAWA YOHEI
IPC: H01P1/203
Filed: 1987-01-23
Abstract: PURPOSE:To easily obtain a desired coupling degree, to simplify the pattern design and to reduce the manufacturing cost by arranging an adjusting thin film to a predetermined position between resonance electrodes at the upper face of a dielectric base and removing the adjusting thin film in a predetermined order so as to vary the degree of coupling of the adjusting thin film linearly. CONSTITUTION:For example, ten pieces of square small thin films 5 made of Ag are arranged at an interval between resonance electrodes 4a and 4c on the upper face of a dielectric substrate 2. After they are subjected to screen print, they are baked and each thin film 5 is removed one by one by trimming in the order of the thin film 51 to 510, that is, in the order of the lower coupling degree K in the interdigital filter 1. Thus, the coupling degree is adjusted linearly. For example, in the case of a coupling degree K8 between resonance electrodes 4a and 4c, the adjusting thin films 51 and 52 have only to be removed. Thus, even if print shear takes place, the coupling degree K is easily and surely adjusted by removing the thin film 5.
