Title: Development color switching device for electrophotographic copying machine
Inventor: IKESUE MASUMI
IPC: G03G15/08
Filed: 1985-03-29
Abstract: PURPOSE:To shorten a color switching time and to reduce the consumption of a developer by providing a means which detects the color tone of a part developed by a developing roller and also detects the detected color tone becoming desired color tone and a display means which indicates that development is ready on a photosensitive body. CONSTITUTION:When colors are changed, the paddle wheel 14 of a developing device 10 is so rotated that the supply roller 24 in a toner chamber in a desired color faces the developing sleeve 12. Then, while toner of the color is supplied to a developer on the developing sleeve, the solid development of the photosensitive body 1 is carried out at specific intervals, so that the color of the developer approximates the desired color gradually. A white light source 3 is turned on and a shutter 5 is opened; and a color filter 4 of the expected color is put in an optical path and then the quantity of light reaching the sensor 2 increases gradually. When the specific color tone is obtained, the output of the sensor 2 coincides with a value stored previously in a comparator 6 corresponding to the color and is outputted to the display means 7, which indicates that the development becomes ready. Thus, the time required fro color changing is shortened and the consumption of the developer is also reduced.

Title: Transmission line identification system
IPC: H04B17/40
Filed: 1992-03-19
Abstract: PURPOSE:To select a transmission line even in the normal operation by differentiating a specific bit used for discriminating a fault of an intermediate relay station from each transmission line. CONSTITUTION:Different binary numbers '1'-'3' as identification numbers (ID) are set respectively to 6 bits in an F1 byte as a specific bit for fault discrimination of an intermediate relay station of an SOH (section overhead) section in a format of an STM frame when an STM frame of, e.g. an SDH(Synchronous Digital Hierarchy) is sent to each transmission line in the trial listening or in the normal transmission by each transmission section in the transmission system. That is, for example, the identification number '2' set to a transmission section is used to identify the transmission section and a number to designate the transmission line up to an intermediate relay station. Thus, the specific bit for fault discrimination of the intermediate relay station is differentiated from each transmission line to identify each transmission line when a receiver side detects the specific bit.

Title: Method for detecting outside of paging radius in private branch radio paging system
Inventor: SAOTOME NOBUAKI
IPC: H04B7/26
Filed: 1993-03-24
Abstract: PURPOSE:To inform a receiver carrier staying outside of a paging radius from a transmitter of that the carrier stays outside of the paging radius in the radio paging system (pocket beeper) small in power conservation and used in a private branch. CONSTITUTION:The transmitter 3 is added with a timer 7 and when a next paging is not executed in spite that a fixed time T passes after paging the receiver 4, the transmitter 3 transmits an invalid signal Y which does not included the paging signal X of the receiver 4 and provides the receiver 4 with a timer 8 to monitor that the transmitter 3 is transmitting. When the power supply of the receiver 4 is activated the timer 8 is reset to start a reception operation and when the receiver 4 receives the paging signal X of its own, the receiver 4 executes call incoming operation and resets the timer 8 at the same time. Even at the time of receiving the paging signal X and the invalid signal Y of another receiver 4, the timer 8 is reset and at the time of receiving none of the three signals even after a time (T+DELTAt) passes, the receiver 4 judges itself to stay outside of the paging radius.
