Title: Cylinder-grinding method for longish substance
Inventor: MATSUBARA HIDEYUKI
IPC: B24B49/02
Filed: 1979-02-28
Abstract: PURPOSE: To reduce the time required for grinding by a method wherein high- feeding rough grinding is performed at a higher speed than that of ordinary rough grinding before the rough grinding being made at an ordinary speed and, moreover, a grinder is kept constantly in touch with a ground object from the start to the end of grinding work.  
     CONSTITUTION: Rough grinding is performed by advancing a grinder 25 at the speed of high-feeding rough grinding and keeping the same in touch with a crank- pin part 17 of an object to be ground. And when the diameter of the crank-pin part 17 has turned to be a length set beforehand, the grinder 25 is made to retreat a little. Meanwhile, the grinder and the crank-pin part 17 are kept continuously in touch with each other since the elasticity of a crank shaft gives a force to the part 17 to return to its original position. After that, the grinder 25 and a steady-rest member 35 is advanced again to carry out precision grinding.

Title: Data processing method
Inventor: KAGE TETSUO
IPC: H01L27/04
Filed: 1991-02-15
Abstract: PURPOSE:To constitute the asynchronous network, and also, to draw out the effect of a parallel operation by decreasing the communication quantity by evaluating strength of coupling of element data by an arithmetic point, when its element data cycleing in the network. CONSTITUTION:When element data cycles in a network 10, strength of coupling of its element data is evaluated by arithmetic points (slave processors) P1-Pn. When it exceeds a prescribed evaluation reference, the number of the arithmetic point at that time is added. Accordingly, in tha case of cycle in the network 10, the number is updated to the number of the arithmetic points P1-Pn whose coupling is the strongest, and at the time of reaching the arithmetic points P1-Pn which coincide with its number, it is allocated to the arithmetic points cencerned P1-Pn. That is, by only throwing the element data into the network 10, an automatic allocation can be executed to the arithmetic points (modules) P<1>-Pn whose coupling is the strongest. Therefore, a comparison processing of an evaluation function between the arithmetic points P1-Pn can be omitted.

IPC: C03B19/00
Filed: 1992-02-07
Abstract: PURPOSE:To prevent defects such as air bells or bubbles from occurring without complicating a forming device and mixing an impurity in filled glass. CONSTITUTION:A raw material in an unmolten state is fed into a plunger chamber 14 and melted only near a nozzle 20 by induction heating to provide molten glass. Since the raw material is rapidly melted and directly injected into a forming mold 22, an impurity is prevented from mixing therein. The molten glass is pressed with a pressing means and injected from the nozzle 20 to fill the interior of a cavity 28 of the forming mold 22. In this case, the molten glass is filled into the cavity 28 from the lower toward the upper parts. The viscosity of the molten glass near a gate 29 is regulated to 10<2> to 10<5>P and the feed rate of the molten glass is regulated to <=10cm/sec. Thereby, defects such as bubbles or air bells are prevented from occurring.
