Title: Speed change gear for automatic transmission
Inventor: ASADA TOSHIYUKI
IPC: F16H3/62
Filed: 1987-06-05
Abstract: PURPOSE:To widen the width of change gear ratio in both the lowest speed change stage and the highest speed change stage by constituting so that the speed change of forward six stages and backward one stage at maximum can be enabled by using two pairs of double pinion type planetary gear mechanisms. CONSTITUTION:The forward first speed in which the change gear ratio is largest can be obtained by connecting a sun gear 3 in a first planetary gear mechanism 1 to an input member, and further fixing both the carrier 11 in the first planetary gear mechanism 1 and the sun gear 4 in a second planetary gear mechanism 2. And when both the carrier 11 and a ring gear 5 in the first planetary gear mechanism 1 are connected to the input member, since the whole rotates integrally, the forward fifth speed in which the change gear ratio is 1 can be obtained. Meanwhile, when the ring gear 5 in the first planetary gear mechanism 1 or a carrier 12 in the second planetary gear mechanism 2 is connected to the input member, and further the sun gear 4 is fixed, the overdrive stage in which change gear ratio is less than 1 can be obtained. On the other hand, when the sun gear 3 in the gear mechanism 1 is connected to the input member and further both the ring gear 5 in the gear mechanism 1 and the carrier 12 in the gear mechanism 2 are fixed, the backward stage can be obtained.

Title: Rewritable optical disk
Inventor: MATSUOKA HIDEKI
IPC: G11B7/2405
Filed: 1992-06-02
Abstract: PURPOSE:To hardly cause interferences between adjacent marks and to enable high-density recording by making recesses or projections in the direction crossing the longitudinal direction of tracks to separate the information recording to be carried out area. CONSTITUTION:A photoresist is first applied on a glass plate, which is then irradiated with two laser beams at one time to form a desired pattern. During patterning, the one laser beam is used to form guide grooves and the other beam is used to form recesses or projections in the direction crossing the longitudinal direction of tracks which separate the information recording area. Then the photoresist is developed with an alkali liquid to remove the exposed area to obtain an optical disk original plate having a rugged pattern on its surface. Then a metal stamper such as nickel is manufactured from this original disk. By using this stamper, disks made of resin on which the rugged pattern is directly formed by injection molding can be obtd.

IPC: B22D11/00
Filed: 1989-06-02
Abstract: PURPOSE:To manufacture a product having large variation of thickness with high accuracy by taking out a mold from molten metal, forming a cylindrical semi-solidified layer having the fixed thickness on the surface of the mold and executing high frequency heating to the above thickness position in this semi-solidified layer. CONSTITUTION:The mold 2 is dipped into the molten metal 2 and taken out from the molten metal to the vertical direction with a lifting member 1 to form the semi-solidified layer 7 having the fixed thickness t1 on the surface of the mold. Under condition of pulling up the semi-solidified layer on the mold surface from the molten metal, the high frequency coil 4 arranged adjacent to the molten metal surface is approached to the semi-solidified layer in the mold surface to execute the high frequency heating. The thickness variable position in the semi-solidified layer on the mold surface is melted and the semi- solidified layer formed on the mold surface is slowly cooled and this thickness t1 is changed into the thin thickness t2.

Title: Preparation of metal copper particle
Inventor: KAWASUMI YOSHIO
IPC: B22F9/20
Filed: 1983-08-04
Abstract: PURPOSE:To obtain a high purity metal copper particle with a desired particle shape and size, in obtaining a copper salt and the metal copper particle by reacting Cu2O with an acid, by controlling a reaction condition. CONSTITUTION:Dilute acid solution is continuously flowed int a reaction tank in such a flow amount that a predetermined stay time is obtained corresponding to the objective particle size of a metal copper particle to be prepared while a Cu2O particle is added at a speed so as to hold the pH of the reaction tank to a predetermined value. If the addition ratio of Cu2O to an acid is made large, the pH of the reaction system becomes high and it is avoided to generate the precipitation of impurities during reaction while, in order to rapidly advance reaction without leaving Clu2O, pH is held to about 2.5 or less. In the next step, a reaction temp. is set to 50 deg.C or less and mutual agglomeration of fine metal copper particles is avoided. In this case, the stay time is a numerical value obtained by dividing the volume of the reaction tank by the inflow and outflow amount of a slurry per a unit time and a metal copper particle with a smaller perticle size is obtained as the stay time becomes shorter. The metal copper particle in a drain liquid is recovered by solid-liquid separation. Furthermore, by raising a reaction temp. to above 50 deg.C, one with a special particle shape can be obtained.
