Filed: 1994-04-26
Abstract: PURPOSE:To obtain a clear color image without being thin in density by transferring the toner images of respective colors on an image carrier on a material to be recorded carried by a carrier for a material to be recorded provided with a grip member without causing defective transfer at the leading edge part. CONSTITUTION:When an elastic layer 3b is formed on the metallic cylinder 3a of a transfer drum 3 with a sponge sheet 3b', the sheet 3b' is wound longer than the fixed point A of the tip part of the layer 3b and only the part thereof to the point A is stuck. Then, a gripper supporting member 3d is moved along the circumferential surface of the cylinder 3a and the leading edge surface of the sheet 3b' is moved to the point A by being pressed and compressed. In such a state, the supporting member 3d is stuck to the cylinder 3a and the raised part B' of the sheet 3b' is eliminated. Then, the sheet 3b' is used as the layer 3b. Thus, the layer 3b and the supporting member 3d are provided in a contact state with a gap of (d) <=0.5mm, substantially without gap. Therefore, since a transfer bias is sufficiently impressed, the clear image is obtained extending over the leading edge part of the material to be recorded.

Title: Method for measuring thin-film strength and protective film for magnetic disk
Inventor: ISHII TOSHIO
IPC: G11B5/82
Filed: 1994-05-24
Abstract: PURPOSE:To make it possible to quantitatively measure the mechanical strength of a thin film of a thickness level of 0.01mum by changing the pressing force of a terminal onto a nonmetallic protective film surface and determining the thin-film strength of this nonmetallic protective film from the pressing force when the digit of the measured resistance value changes suddenly. CONSTITUTION:The electric resistance on the thin film surface is kept measured at the time of low load when the pressing force onto the thin-film surface by a stylus (terminal for measurement) is changed while the electric resistance on the thin-film surface is measured by a stylus type electric resistance measuring instrument. The thin film is broken with an increase in the load of the measuring element and the measured value of the electric resistance is suddenly changed by contact of the measuring terminal with the ground surface of the thin film. The pressing force when the thin film is broken, is measured from the change in the electric resistance thereby, the strength of the thin-film itself is determined. The protective film which prevents rapid changing of the electric resistance of the magnetic disk surface under the pressing force <=250g/mm<2> of the magnetic disk is obtd., thereby, the magnetic disk having the excellent CSS characteristic is obtd.

IPC: H02M7/515
Filed: 1988-05-02
Abstract: PURPOSE:To prevent a GTO from being broken by transient vibration. by directly connecting diodes in parallel, etc., to snubber capacitors. CONSTITUTION:A snubber circuit of a GTO inverter is composed of GTO 1U-1X, the arm elements, reactors 2U-2X, feedback diodes 3U-3X, snubbers 4U-4X, a diode circuit 5, a current transformer 6, a diode rectification circuit 7, etc. On this occasion, diodes 43U-43X are connected to each snubber capacitor 41U-41X in parallel. Thus, if the polarity of the snubber capacitor 41X is going to be negative, the voltage level in negative polarity of the snubber capacitor 41X will be clamped to a very small value as the diode 43X gets conducting. As a result, the influence of the GTO 1X is reduced since the vibration phenomenon so far observed is diminished.

Title: X-ray measuring instrument
Inventor: GIN HOI RII
IPC: G01T1/20
Filed: 1990-04-25
Abstract: PURPOSE: To miniaturize a measuring instrument by applying a measuring signal to an input of an integration circuit when a first switch is closed. CONSTITUTION: When a first switch 41 is closed, a measuring signal is applied to an input of an integration circuit, and the measuring signal is directly applied to an integrator without preceding amplification. By using the capacitive feedback the safety problem that occurs during amplification due to feedback of an output signal opposing through a relatively large feedback resistance is avoided. A measuring signal of a photodiode 26 is converged over a feedback capacitor 33 during a converging period (10ms, for example) determined by a period of closing of the first switch 41, and an output voltage of the integrator is proportional to an average detector current. Thereby, a rigid, small-sized detector can be obtained.
