Title: Method of vacuum-casting synthetic resin liquid and apparatus therefor
Inventor: HAYASHI YUKIO
IPC: B29C67/24
Filed: 1990-07-17
Abstract: PURPOSE:To manufacture a model without containing bubbles therein by stir-mixing synthetic resin liquid in a first vacuum chamber while exhausting cells, and then transferred to a evacuated second vacuum chamber, and further injecting it by utilizing differential pressure from the lower injecting port of a casting mold situated thereon. CONSTITUTION:A pinch valve 19 of a transferring tube 16 is closed, and a measured main agent and a curing agent are put into cups 4, 5, and then a vacuum chamber 11 is allowed to be evacuated by means of a vacuum pump 1, and further the curing agent in the cup 5 is stirred and degassed for a limited time by means of a stirring machine 9. The vacuum chambers 11, 12 are made a set vacuum degree and, by the stirring machine 9, the main agent in the cut 4 is stirred and degassed for a limited time, following this, by a magic hand 14, the curing agent is poured into the main agent in the cup 4 and, by the stirring machine 9, the mixed liquid is stir-mixed for a limited time, and further the mixed liquid is poured in a pan by a magic hand 13. The vacuum degree of the vacuum chamber 12 is made higher than that of the vacuum chamber 11 and, when the pinch valve 19 is opened, the mixed liquid is automatically poured therein by the differential pressure between the vacuum chambers 11, 12 from the injection port 17 on the underside of a casting mold body M. By the foregoing description, the existence of cells becomes less in the mixed liquid.

IPC: G01F23/292
Filed: 1994-08-10
Abstract: PURPOSE:To easily exchange a waste toner storing container positioned on the back surface side of a copying machine main body.

Title: Memory system
Inventor: RATSUSERU UIRIAMU RABARII
IPC: G06F12/16
Filed: 1992-07-16
Abstract: PURPOSE: To dynamically discriminate an extremely large number of defective bit positions of an ECC(error correction code) data word. CONSTITUTION: This memory system holds a recording counter 224 for each data bit in an ECC data word. When one counter is incremented beyond a prescribed threshold value, the system calls sparing for substituting a faulty bit position. When a preliminary chip is specially designed for substituting a defective chip, the system continues writing in the defective chip in parallel to the preliminary chip even after the bit sparing is called. Thus, when the substitute chip is accidentally turned into an off-line, the reliability of data on the substitute chip can be enhanced.

Filed: 1986-08-13
Abstract: PURPOSE:To always attain perfect YC separation and to prevent the generation of switching noise by detecting interrelation between signals supplied to each of plural comb line filters and applying weighted addition to output signals of plural comb line filters according to plural interrelation detection information. CONSTITUTION:Comb line filters are constituted respectively of 1H delay circuits 13, 14 and adders 17, 18, and adders 15, 16 and detectors 19, 20 constitute respectively detector circuits..
