Title: Printer
Inventor: YONEDA KAZUHIRO
IPC: B41J29/00
Filed: 1986-04-09
Abstract: PURPOSE:To prevent an offensive odor generated at the time of printing from being diffused into the atmosphere and obtain a pleasant working environment, by providing a sucking means for collectively sucking an odor generated at the time of printing, and a deodorizing member for elimination the odor sucked by the sucking means. CONSTITUTION:When printing is started and a printing head 4 is moved, for example, from left to right for printing in a line, a substance constituting an odor source is formed due to the contact of the head 4 with a printing ribbon 3 in the vicinity of the part of the contact, and starts being diffused into the atmosphere. The rightward movement of the head 4 is accompanied by a movement of a piston 6 in the same direction. By this movement, a negative pressure for suction is generated in a pressure chamber P to open a suction valve Vs, and an exhaust valve Ve is operated in a direction for closing, whereby the odor source substance generated at the time of printing is collectively sucked into the pressure chamber P through a suction pipe 7. When the head 4 is moved leftward in a returning operation, the piston 6 is moved following this, the odor source substance is subjected to deodorization by a catalyst member 9 in a converter part 8a, and is released into the atmosphere in a substantially odorless state.

Title: Limit circuit
Inventor: MIZUKAWA YOSUKE
IPC: H03G11/00
Filed: 1989-03-31
Abstract: PURPOSE:To facilitate the adjustment of a limit level and to eliminate a gain adjustment terminal by installing a means which changes proportionally the constant current values of constant current sources in a first stage and a second stage in a Gilbert type differential amplifier and changing the limit level without changing a gain. CONSTITUTION:Transistors 2 and 3 forming the differential amplifier in the first stage is connected to the constant current source 6 through emitter resistances 4 and 5. The emitters of transistors 19 and 20 forming the differential amplifier in the second stage are connected to the constant current source 21. An input signal from a signal source 1 is inputted to the base of the transistor 2. The Gilbert type differential amplifier is constituted by the differential amplifier of a diode load in the first stage and the differential amplifier in the second stage. The circuit gain is proportional to the resistant rate of the differential amplifiers in the first and second stages, and also to a current rate. Consequently, the limit level can be changed without changing the circuit gain because the limit level of an output is decided by the constant current value in the second stage although the circuit gain does not change by proportionally changing the constant current values of two constant current sources 6 and 21.

Abstract: PURPOSE:To effectively utilize the path area of a basket by moving a basket receiving guide in a direction to press the basket according to the change of the angle of a reading part. CONSTITUTION:When the reading part 16 is turned in a counterclockwise direction from a perpendicular state centering an axis 15, a pin 26 is moved backward, thereby, arms 23 and 24 are turned in a clockwise direction centering a axis 22. Then, since the elongated holes 27 of the arms 23 and 24 are moved forward, the basket receiving guide 14 is moved in the direction to press the basket 1 via a pin 28 engaged with the elongated holes 27 of the arms 23 and 24, then, the basket 1 is separated from the reading part 16. Thus, by providing a moving mechanism 21 to move the basket receiving guide 14 in the direction to press the basket 1 when the reading part 16 is inclined centering the axis 15, no trouble occurs even when the angle of the reading part 16 is changed since the basket 1 is also separated from the reading part 16 according to the above change. In such a way, the path area of the basket 1 can be effectively utilized.

Abstract: PURPOSE:To reduce the variance of electric discharge and the generation of ozone to control electrification of an image forming body accurately and easily by applying an AC voltage to a discharging wire of a scorotron corona discharger which electrifies the image forming body. CONSTITUTION:If the AC voltage is applied to a discharging wire 1, which has only side faces surrounded with a casing 3 and consists of the scorotron corona discharger, from an AC power source 4 through a capacitor 5, the potential of electrification of an image forming body 7 is controlled with a high precision because it is changed linearly by the voltage of a grid 2. Since a DC voltage is applied to the grid 2 and the casing 3 from a DC power source 6, the discharging wire 1 discharges electricity uniformly and stably to uniformly electrify the surface of the image forming body 7. If 4-6kV and 1-20kHz voltage is applied to the wire 1, the surface of the image forming body is quickly electrified and the generation of ozone is suppressed.

SiO2 glass particulates are thereafter deposited over the entire surface and are vitrified to transparent glass. The preform for the multicore fiber ribbon is thus obtd. The process for production of such preform merely involves the precise production of the substrate which is a starting material. The subsequent formation of the glass to constitute the cores and clads is easy. The desired multicore fiber ribbon is thus easily obtd.
