Title: Image forming device
Inventor: MIYASHITA YOSHIAKI
IPC: G03G21/10
Filed: 1993-11-05
Abstract: PURPOSE:To achieve extremely-steady, uniform electrification which prevents an occurrence of an image defect over a long period of time. CONSTITUTION:The device is equipped with a controller 30 for ordinarily keeping a cleaning member 22, used for cleaning the surface of an electrifying roller 2 which is in contact with a photoreceptor 1, apart from the surface of the roller 2, and for allowing the contact of the cleaning member 22 with the electrifying roller 2 only for a fixed time by driving a cleaning member contact/ separation mechanism 10 at each timing, at prescribed time-intervals. Thus, because excessive cleaning of the electrifying roller 2 by means of the cleaning member 22 is eliminated, an occurrence of an image defect can be prevented. Also, sudden soiling of the electrifying roller 2 can be handled by providing a means for detecting the degree of the soil of the surface of the electrifying roller 2, and by varying the timing that the cleaning member 22 is brought into contact with the roller 2, according to the degree of the soil.

IPC: F42B3/12
Filed: 1991-09-28
Abstract: PURPOSE:To keep a stable sealing and fixing of a plug by a method wherein as the plug, ceramics having a superior anti-heat characteristic is used, and a sealing glass is filled and fixed between the plug and a lead pin. CONSTITUTION:Glass 4 filled within a metallic inner cylinder 3 seals and fixes among a lead pin 2, a ceramic plug 1 and a metallic inner cylinder 3. In the case that glass is installed when a plug A is manufactured, the metallic inner cylinder 3 and the lead pin 2 are made of material quality approximating to a coefficient of thermal expansion of the glass 4 as well as ceramics 1 in such a way as no cracks are generated at the sealing glass 4 or the ceramic plug 1 under a heat stress generated by a difference of coefficients of thermal expansion of each of the members. For example, the lead pin 2 may be made of nickel iron alloy and the metallic inner cylinder 3 may be made of stainless steel. Outer diameter of the flange part 11 of the ceramic plug and outer diameter of a leading end 310 of the metallic inner cylinder 3 are slightly smaller than an inner diameter of the metallic outer cylinder 6.

Title: Method and system for radio channel switching of mobile body communication
Inventor: ITO SADAO
IPC: H04B7/26
Filed: 1987-11-02
Abstract: PURPOSE:To preclude a momentary break of a communication at the time of radio communication channel switching and interference disturbance to other channel by sharing the same radio communication channel on a time-division basis. CONSTITUTION:For example, a mobile radio equipment is communicating with a radio base station 30-1 over a channel CH1. When the mobile radio equipment moves away from the base station 30-1 to a base station 302, the communication quality begins to deteriorate. A gateway exchange 20 on knowing the deterioration in the communication quality turns on switches SW1 and SW2 in a switch group 23 at the same time and requests the base station 30-2 to send out the same communication signal with the base station 30-1. Consequently, the base station 30-1 receives the channel CH1 and a control channel alternately. Then, when the mobile radio equipment selects the 30-2 as a radio base station which meets constant communication quality, the mobile radio equipment and base station 30-2 makes a communication over a new channel CH2.

Title: Optical a/d converter
Inventor: NAITO SEIICHI
IPC: G02F7/00
Filed: 1986-11-21
Abstract: PURPOSE:To increase a conversion speed by using a spatial optical modulator and utilizing the parallelism of light. CONSTITUTION:An electro-optic converter 2 inputs an analog input signal to be converted and outputs a light signal proportional to the input. The light from a reference light source 1, on the other hand, is made incident on the spatial optical modulator 4 through a lens system 3. The modulator 4 is equipped with, for example, 16 filters, whose degrees of attenuation are classified by 16 stages. The light from the light source 1 is therefore classified by 16 stages of light intensity. Further, slits 10 divide light from an lens system 6 into 16 equal parts and each slit allows light proportional to the input signal to pass. A half-mirror 5 transmits the light from the modulator 4 and also reflects light transmitted through the slits 10 to make the light incident on a photodetector array 7. The array 7 is provided with photoelectric converting elements FD1-FD16 in array and outputs the difference between both input signals to an encoding circuit 8. The circuit 8 converts the output signal of the array 7 into a binary signal.
