Title: Method for monitoring change of light loss in optical transmission line
Inventor: MIYAJIMA YOSHIAKI
IPC: H04B3/46
Filed: 1987-09-04
Abstract: PURPOSE:To measure the loss of a optical transmission line while it is used for communication, by coupling a monitoring signal having a different wavelength by using an optical multiplexing/demultiplexing element, and separating the monitoring signal according to the wavelength at an emission end, and obtaining the change of a light loss of the optical transmission line from the level change of the separated monitoring signal. CONSTITUTION:A transmission, equipment outgoing part 3 which outputs a transmission signal of the wavelength lambda1, a monitoring signal light source 5 which outputs the monitoring signal of wavelength lambda2 different from the wavelength lambda1, and the light multiplexing/ demultiplexing element 2 which multiplexes the transmission signal and the monitoring signal and sends it to the optical transmission line 1 from a junction point 7, are provided. Further, at the emission end of the optical transmission line 1, the light multiplexing/demultiplexing element 2' which is connected to the optical transmission line 1 at the junction point 7' and separates the transmission signal and the monitoring signal according to the wavelengths, a transmission device receiving part 4 which receives the transmission signal, and a monitoring signal receiving part 6 which obtains the change of the light loss of the optical transmission line 1 from the level change of the separated monitoring signal, are provided. Thus, the change of the light loss of the optical transmission line can be monitored simultaneously while the transmission signal is transmitted. Therefore, it is not necessary to interrupt a service for measuring the light loss, and the transmission line can be always monitored.

Title: Transfer device
Inventor: MASUDA JITSUO
IPC: G03G15/16
Filed: 1986-09-19
Abstract: PURPOSE:To improve picture quality by providing a control plate which controls an area charged electrostatically by a transfer charger to in front of a point where a transfer form contacts the surface of a photosensitive drum in a rotating direction to a form conveyor guide for the transfer form, and composing the control plate of an insulating member. CONSTITUTION:The point where the transfer form A is guided by the form conveyance guide 4 to contact the photosensitive drum 1 is denoted as a contact point P and when the transfer form A is charged electrostatically before the contact point P in the rotating direction of the photosensitive drum, no toner is scattered over the transfer form. For the purpose, the control plate 5 is arranged on the opposite side of a flat plate 41 from the photosensitive drum 1. Therefore, a corona ion flow generated by applying a high voltage to a charger wire 3 is not projected behind the contact point P where the transfer form A contacts the photosensitive drum 1, so the transfer form which does not contact the photosensitive drum 1 is never charged electrostatically. Consequently, toner on the surface of the photosensitive drum 1 is never attracted by the transfer form which does not contact the photosensitive drum to scatter over the transfer form.

Title: Circuit forming board, method and apparatus for forming circuit forming board
Inventor: NISHII TOSHIHIRO
IPC: H05K1/11
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To realize high quality boring without sacrifice of high speed energy beam machining by providing a diffusion preventive means on the inner wall of a through hole or a via hole where a connecting means, or at least the conductive substance therein, is not diffused to the outside. SOLUTION: When a through hole 15 is made by irradiating a board material 11 with a laser beam 14, thermosetting resin 12 and aramid fibers 13 in the board material 11 are thermally sublimated and scattered to the surroundings. When correct machining conditions are set, the aramid fibers 13 are integrated through fusion, for example, in the vicinity of the inner wall of a hole to form a diffusion preventive means, i.e., a quality change layer 16. Bonding reliability can be enhanced by conducting hot press while leaving only conductive particles on a conductive paste 17 selectively in the through hole 15 thereby increasing the density of the conductive particles sufficiently in the through hole 15 after hot press.

Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To increase an awareness of water economization by providing an integrating flow display section and a rate display section at the end of waterworks such as a faucet of a home. SOLUTION: When a faucet 7 is used, a momentary flow is detected by a flow meter 8 and an accumulated flow for a prescribed period of time is detected by an integrating flow meter 9 and displayed on a flow display section 11 and an integrating flow display section 12, respectively, making it possible to keep track of a tap water consumption condition while the faucet is used. And then a flow corresponding to the prescribed period of time is stored in a storing section 13, displayed on a result display section 14, and compared with the use for the same month a year ago for example. And then when necessary, a rate computation section and a rate display section are connected to the integrating flow meter 9, and an accumulated flow is converted into a rate, helping keep track of a tap water rate.  In addition, all the integrating flow meters 9 are connected to a totalizing section to totalize and display an accumulated flow for each terminal, thereby making it possible to adjust a flow as an amount of a substance rather than sensually. Therefore, excessive use can be restrained and an awareness of water economization can be heightened.
