Filed: 1993-06-08
Abstract: PURPOSE:To increase two different functions of wiping off of toner which is offset and adhered and uniform coating of cleaning oil by making two types of different cleaning members with the surface of a fixing roller. CONSTITUTION:A cleaning unit 21 is provided with two felts 23 and 24 as cleaning members which are made in contact with the surface 13a of a heat roller 13, arranged contactedly with each other in rotating direction, longer in the axial direction of the heat roller 13, and different in hardness and density from each other. In this case, the felt 23 which is made in contact first with the heat roller 13 at rotating is small in density, small in hardness, and flexible than those of the felt 24 which is made in contact later, and thus the holding property of silicone oil is high. On the other hand, the felt 24 is larger in density and hardness than those of the felt 24. Thus adhered toner 5 that cannot be wiped off by the felt 23 is wiped off further by the felt 24 which is larger in hardness than the felt 23, and a surface 13a can be cleaned and the coating of the silicone oil is further uniformed.

IPC: G01N1/28
Filed: 1984-08-06
Abstract: PURPOSE:To prevent the curving of the top surface of a bead by providing a plane forming stage in the cooling process after a melting and stirring stage and holding ore for >=5sec at the prescribed temp. within the range of the solidifying temp. of the ore +10-500 deg.C. CONSTITUTION:The powder ore is melted by a flux and stirred uniformly in the melting and stirring stage. The molten ore is held for about >=5sec in the range of the solidifying temp. of the ore +10-500 deg.C in the plane forming stage. The temp. at which the plane is formed varies with the kind of the flux, the peeling agent to be added and the side wall angle of a platinum vessel and therefore the optimum temp. is preferably selected for each of the conditions for bead production. The molten ore is allowed to cool down to a room temp. after the plane forming stage as a cooling stage. The curving of the top surface of the bead is thus prevented and the bead sample optimum for a fluorescent X-ray analysis is thus obtd.

Title: Pickup device
Inventor: IZUMI YASUHIKO
IPC: H04N5/335
Filed: 1978-12-26
Abstract: PURPOSE: To prevent the blooming phenomenon by distributing the filters featuring the different light transmittance to the pickup element groups alternately.  
     CONSTITUTION: With no blooming, the video signals passed through the optical filter of a high transmittance emerges alternately at output terminal 22 from gate circuits 20 and 21. When the blooming occurs, comparator circuit 26 detects that the video signal is larger than the reference signal of terminal 25. Thus open gate circuit 20 or 21 is closed; while closed gate 21 or 20 are opened. As a result, the signals are turned into the video signals which passed through the low transmittance filter only at the region where the blooming occurs. And in case the blooming is still existing in the signals of terminal 22, comparator circuit 28 detects the blooming for controlling filter 3 which is variable for the transmission amount.

Title: Semiconductor device
Inventor: ISHIBASHI MASARU
IPC: H01L21/60
Filed: 1990-06-22
Abstract: PURPOSE:To keep the independence of a chip at a central section and a chip at an end section constant, and to operate each chip uniformly by successively making the loop angles of bonding small-gage wires connecting a semiconductor element and a MOS-capacitor for an internal matching circuit differ toward the small-gage wires existing on the outside from the small-gage wires existing on the inside. CONSTITUTION:When end sections are mismatched because the reactance of output side circuit at the end sections is made smaller than the central sections of each transistor chip 1, the junction temperature of the cell-A of the transistor chip 1 is made higher than other cells by approximately 20 deg.C. The loop angles thetaof Au wires 3b, 3c are increased successively so as to compensate extremely small reactance in cells at the end sections by Au wires 3 in the transistor chip 1. Consequently, the decrease of reactance to the cell A is eliminated, a matched state is brought, and the junction temperature is lowered, and reaches a temperature in the same extent as other cells. Accordingly, each cell of a transistor is operated uniformly, and an output from the transister is increased while an MTTF is also improved.

Title: Manufacture of seamless steel tube
Inventor: OYADOMARI NORIAKI
IPC: B21B17/00
Filed: 1993-07-02
Abstract: PURPOSE:To manufacture a highly strong seamless steel tube having little surface flaws by straightening in a specified range of temperature after a hot rolled seamless steel tube is sized, cooled to specified temperature range in a low oxygen atmosphere and descaled. CONSTITUTION:When the seamless steel tube is manufactured by heating, piercing, rolling, sizing and straightening a billet, the rolled and sized steel tube is slowly cooled to 500 to 600 deg.C in the low oxygen atmosphere to slowly grow scale. Descaling is carried out in a short time and straightening is carried out at the temperature at which no scale is generated, when the tube is corrected at 450 to 550 deg.C after descaling. Thus, the generation rate of thrust flaws caused by scale and the generation rate of reduction in strength caused by variation in straightening temperature are largely reduced when compared to conventional methods.
