Title: X-ray camera
Inventor: YASUHARA HIROSHI
IPC: H05G1/64
Filed: 1979-05-10
Abstract: PURPOSE:To permit the reduction of the dose of radiation as well as obtain a desired timing of X-ray photographing while making an X-ray fluorescopic operation by providing a secondary electron multiplier to multiply the output of optical images from an X-rays-fluorescence converter. CONSTITUTION:When a voltage and current matching a photographing condition is given to the X-ray tube, X-rays generate, pass through the object 2, enters the incidental face of the X-ray image multiplier 3, and then focuses into an X-ray image. The secondary electron multiplier 4 is provided on the output side of the X- ray image multiplier 3, by which X-ray image is multiplied to approximately 10<4> and converted into a clear optical image which is, in turn, focused by the lens of the optical system 7 and then distributed to the television camera 8 and the still camera 9 by the half mirror 7a. Thus, because the optical image distributed to the still camera 9 is made to have a sufficient intensity of radiation, photographing on the film 9b can be performed any time by operating the shutter 9a of the camera 9 during the fluorescopic operation at a low-output X-ray load.

Abstract: PURPOSE:To detach the unfixed developer on a recording material from a fixing roller and to prevent the offset thereof by impressing the voltage of the polarity reverse to the electrifying polarity of the developer on the mandrel of a pressurizing roller. CONSTITUTION:The fixing roller 10 constituted by forming a release layer 101 on the front layer of the mandrel 102 consisting of a good conductor metal, such as aluminum, is used. The bias voltage divided by resistors R1', R2' from the output of a high-voltage power source 14' for supplying the bias voltage to a transfer roller 8 is impressed to the mandrel 113 of the pressurizing roller 11'. Positive-polarity charges are accumulated on the elastic conductive layer 112 side in the part where the fixing roller 10 and the pressurizing roller 11, are nipped. On the other hand, negative-polarity charges are induced on the mandrel 102 side, by which the electric field for repulsing the negative-polarity toners constituting an unfixed sensible image 6' from the fixing roller 10 is formed and the generation of the offset image is suppressed. The bias voltage to be applied to the mandrel 113 is determined by the resistance values of a rubber layer 112 and the release layer 101 and is preferably in a range from +200 to +2000V.

Title: Optical transmitter and receiver
Inventor: NABEYAMA YOSHIO
IPC: H04B10/079
Filed: 1995-03-16
Abstract: PURPOSE: To simplify the switching processing between the active and stand-by systems by monitoring the input optical signals at the optical cut-off detection part of an optical amplifier circuit prepared at an active optical transmission part and switching an active system to the stand-by system in an input cut-off state by stopping the operation of the optical amplifier circuit. CONSTITUTION: The optical signals are transmitted from an electricity/light conversion means (OS, 5 of an active optical transmission part 1 via an optical amplifier circuit 3 and an optical connector 8. At the same time, the optical signals sent to an amplification part 3a of the circuit 3 from the OS2 are monitored by an optical cut-off detector 3b. When an optical cut-off state is detected, the operation of the part 3a is stopped by the detection output of the detector 3b. Then the part 1 is switched to a stand-by optical transmission part 4 by a switch means 7. Then the optical signal retrogressing on an optical cable is detected at an optical reflected light detection part 6c as long as an optical connector 9 of the part 4 is opened. Thus the operation of the OS 5 is stopped, so that the large output light emitted from the open connector 9 is prevented.  As a result, the satisfactory switching processing is simplified between both parts 1 and 4.
