IPC: G03G15/05
Filed: 1984-11-16
Abstract: PURPOSE:To obtain clear images free of fog, by providing a moving recording medium, a developing means comprising a developer carrier for carrying a conductive developer, and a recording electrode means for adhering ions onto the recording medium. CONSTITUTION:When a signal voltage indicative of the presence of an image signal is impressed on the second electrode in accordance with image information, ions are adhered to the recording medium 1 in a pattern corresponding to the image. Simultaneously, electric charges of the polarity opposite to the polarity of the ions are injected into a toner T through a sleeve 5, and by the electrostatic attraction between the ions and the toner, the toner is attracted toward and adhered to the recording medium 1, whereby a visualized toner image is formed on the medium 1. When there is not image signal, the second electrode 9 is maintained at 0V, so that adhesion of the toner T to the medium 1 does not occur. By maintaining the fourth electrode 17 and the sleeve 5 at substantially the same potential, fogging of images is prevented from occurring, and clear images are obtained.

Title: Facsimile equipment with sequential transmission function
Inventor: ASADA HIRONORI
IPC: H04M11/00
Filed: 1987-09-29
Abstract: PURPOSE:To improve the operation rate of sequential transmission function by allowing the operator to select the original sending time and the original sending destination registered in advance for the reservation of original sequential transmission. CONSTITUTION:The operator uses a sequential transmission registration means 6 in advance to register the transmission destination of an original and the original sending time to the destination into plural sets of memories 5. When the operator selects a desired original sending time registered in the sequential transmission registration means 6, the sequential transmission designation means holds the selected transmission time and the destination corresponding thereto and informs it to the sequential transmission means. The sequential transmission means sends the sending time stored by the sequential signal designation means and the data in the picture memory 3 having the destination in the lump in the order of transmission time arrival to the destination. Thus, even when the destination is the same, the inoperative sequential transmission function due to a slight difference in the transmission time regardless of the same destination is avoided.

Title: Method for forming alpha plus beta titanium alloy stock
Inventor: TAKEMURA ATSUSHI
IPC: C22F1/18
Filed: 1988-09-27
Abstract: PURPOSE:To carry out the forming of the title stock without causing the occurrence of defects at a speed as high as 10-200%/sec strain rate by regulating deformation value per time in a specific temp. region to a specific value or below at the time of subjecting a Ti-6Al-4V alloy stock to hot tensile deformation under nonconstraint. CONSTITUTION:At the time of subjecting a Ti-6Al-4V alloy stock to unconstrained forming into the final product shape by applying hot high-speed tensile deformation to the stock, the amount of deformation per time is regulated to <=35% in the case when forming temp. is in the range between 950 deg.C and (beta-transformation point -5 deg.C), and, when forming temp. is in the range between 850 deg.C and 950 deg.C, the amount of deformation per time is regulated to <=10%. Further, 10-200% of high-speed tension, that is, strain rate is necessary to improve productive efficiency, but, since the generation of heat attendant on the plastic deformation of the alloy stock is remarkably increased when the strain rate exceeds 200% and there are cases when the temp. of the alloy stock exceeds the beta-transformation point due to the above generation of heat, the strain rate is limited to 10-200%. Forming free from defects is made possible under the above conditions, and forming can be efficiently carried out in a short time.
