Filed: 1994-01-20
Abstract: PURPOSE:To facilitate the connection of a bus by applying a prescribed arithmetic processing to the decided data having a necessary output number among plural data and outputting the processed data to a bus together with the output number proper to a relevant device. CONSTITUTION:The data on the temperature, etc., supplied to an input device 3 from the outside undergo the necessary processings such as the linearization, etc., and then are outputted to a bus L together with a proper output number of the device 3. Meanwhile various devices are connected to the bus L and different output numbers of these devices are sent to the data on the bus L. Then the data flowing on the bus L are fetched by the arithmetic units 1 and 2 and an output device 4. Thus the device 4 decides and selects only the data that has the output number of the device 3 coincident with the corresponding fetched number. Then the device 4 can output the selected data to the outside. Thus only a single common bus L suffices and complicated wiring is needed.

Filed: 1995-02-08
Abstract: PURPOSE: To prevent the clogging of a pipeline by exciting each electromagnet so that a vibrator with a magnetic body provided inside pipe material continuously approaching and separating from the facing electromagnet. CONSTITUTION: When an alternating current flows to a coil 19c, each electromagnet 19 is excited so that the core one end 19a and the core other end 19b alternately become N-pole or S-pole, and the polarity of the core one end 19a and the core other end 19b is changed. The attraction and repulsion of each permanent magnet 18 to the electromagnet 19 are therefore repeated in a cycle corresponding to the frequency of the alternating current. As a result, a moving frame 16 comes in intermittent contact with the pipe material inner surface 14a and the anti-pipe-material inner surface side end part of a pin 17, so that the pipe material 14 is vibrated to prevent dust from adhering to the pipe material inner surface 14a. The clogging of the pipe material 14 can thereby be prevented.

Filed: 1993-02-09
Abstract: PURPOSE:To make detection of the density easy and to obtain excellent stability and charge stability by incorporating a binder resin and a specified black coloring agent to increase the difference of reflectance from the carrier in the IR region. CONSTITUTION:This toner for development of electrostatic latent image contains a binder resin and C.I.Pigment Black 31. The C.I.Pigment Black 31 not only functions as a black coloring agent but enables accurate detection of the developer density since the pigment has enough reflectance for IR rays. By this method, the amt. of the coloring agent used is decreased compared with a black toner obtd. by compounding several kinds of dyes and pigments other than black, and the obtd. toner has excellent charging property and fixing property. To increase the black degree, carbon black may be used. In this case, it is necessary that the amt. of carbon black used is <=5 pts.wt. to the binder resin in order to maintain proper absorptivity for IR rays.
