Title: Image forming device
Inventor: SATO NORIBUMI
IPC: G03G15/02
Filed: 1995-07-03
Abstract: PROBLEM TO BE SOLVED: To detect the rotational speed of a latent image carrier on a short cycle by detecting the rotational amount of an electrostatic charge roll by using a rotational amount detection means fitted to the rotary shaft of the electrostatic charge roll. SOLUTION: The rotational amount detection means 11 is formed on the rotary shaft of the electrostatic charge roll 8 and constituted of a rotary plate 11a obtained by forming plural through-holes on an identical circumference and a light emitting element 11b and a light emitting element 11c which are arranged to be faced through the identical circumference. Then, a pulse is generated by the element 11c every time that the light of the element 11b is made incident because the through-hole is positioned between the elements 11b and 11c.  Therefore, the electrostatic charge roll 8 whose diameter is smaller than a photoreceptor 1 is rotated at a higher speed than the photoreceptor 1 in accordance with the rotation of the photoreceptor 1 and the rotational amount of the roll 8 is detected by the detection means 11 so that the number of pulses outputted from the detection means 11 while the photoreceptor 1 is rotated once is increased.

Title: Special worm screw and thread groove cutting method and device therefor
Inventor: MACHINAGA HIROFUMI
IPC: B23G1/38
Filed: 1992-06-25
Abstract: PURPOSE:To shorten the cutting time of the thread groove of a special worm screw by separating a cutting tool from screw base material every time the continuous cutting action of a specified cycle is terminated, and resuming cutting after adjusting the angle-of-rotation position of the screw base material into the initial position of starting slitting to cut the thread groove. CONSTITUTION:Circular arc shape grooves connecting, at both ends thereof, a going thread groove A to a return thread groove F in relation to an axis are formed by connecting linear grooves B-E and G-J of different lead, and the quantity of cutting depth is increased every time the continuous cutting of one cycle from the groove A to the groove J is terminated. Every termination of the specified cycle, a cutting tool is once separated from screw base material, and cutting is resumed after readjusting the angle-of-rotation position where the slitting of the screw base material is started.

Filed: 1990-06-26
Abstract: PURPOSE:To prevent data communication from being leaked to a speech line even when an inexpensive cable is in use by recognizing whether or not the system is in talking state and using a control means in talking state so as to interrupt the base band communication. CONSTITUTION:A supervisor's room, a front door lobby and each housing are interconnected by a 4-wire cable comprising a couple of speech wires and a couple of data wires to attain base band communication and when the talking of a terminal equipment is started, a central monitor panel uses a speech detection section to recognize speech information and the transmission of data communication is interrupted to increase a voltage of the data line from V1 to V2, a voltage level detection section at a terminal equipment detects the voltage thereby interrupting data communication of itself for each prescribed time. Thus, leakage of data communication to the speech line is avoided and an inexpensive cable is used without deteriorating the speech quality.
