Title: Electrophotographic sensitive body
Inventor: TANAKA MASAFUMI
IPC: G03G5/06
Filed: 1987-11-30
Abstract: PURPOSE:To obtain an electrophotographic sensitive body having high sensitivity and generating a small residual potential by incorporating a specified compd. Into a photosensitive layer. CONSTITUTION:A photosensitive layer is formed on an electroconductive base material of an electrophotographic sensitive body, and a compd. expressed by formula I is contained in the photosensitive layer. In formula I, each R<1>-R<6> is H, lower alkoxy group, etc.; R<7> is H or aryl group, etc. The compd. may be used singly or as a mixture of >=2 kinds. Since the compd. causes no isomerization reaction by the irradiation with light and has high compatibility with a binder resin, etc., the compd. has high drift mobility and the dependency of the drift mobility on electric field strength is small. Thus, an electrophotographic sensitive body having high sensitivity and generating small residual potential is obtd.

Title: Video signal coder
Inventor: KASEZAWA TADASHI
IPC: H04N19/196
Filed: 1999-10-25
Abstract: PROBLEM TO BE SOLVED: To continuously conduct normal coding even when receiving a signal with a format that is not normal. SOLUTION: A coding frame pulse generating means 9 uses a video input frame pulse 105 to set once a reference phase, subsequently frequency-divides a prescribed number of video input clocks 104 and generates a coded frame pulse 106 by using a self-running clock. A video signal read control means 6 controls reading of a video input signal 101 by a video signal rearrangement means 3 on the basis of the coded frame pulse 106. Furthermore, an input frame period detection means 7 detects the period of one frame of a video input frame pulse 105 and an input output frame phase difference detection means 8 detects the phase difference 108 between the video input frame pulse 105 and the coding frame pulse 106 for each frame and outputs it to a video signal read control means 6.

Title: Print stopping method for printer
Inventor: NAGASU TAKASHI
IPC: B41J11/42
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent print quality from deteriorating due to operation during print interruption by releasing a fixing roller from press contact after a perforation is carried to a press contact point or a vicinity thereof in response to a print interruption signal and then carrying the perforation to a stop position on the upstream side of a transfer point in the carrying direction of recording material. SOLUTION: Upon receiving a print interruption signal, a printer controls deceleration of motors 13, 14 to stop a heating roller 10 and a perforation B being carried by a tractor 6 at the press contact point of the heating roller 10 and a press roller 11. Upon elapsing a predetermined time after receiving the print interruption signal, operation of a motor 15 is started and the press contact point of the heating roller 10 and the press roller 11 is released. Subsequently, the motor 13 is carried back in the direction of a hopper such that a perforation C is located closer to the hopper 17 side by a distance L from the transfer point. Since a unprinted perforation C stops at a position closer to the hopper 17 side by a distance L from the transfer point, deterioration of print quality due to operation during print interruption can be eliminated.

Title: Charged particle beam monitor
Inventor: TORIKOSHI MASAMI
IPC: H01J47/02
Filed: 1989-11-22
Abstract: PURPOSE:To accurately measure charged particle beams having different expanses in different directions by setting the interval between the surfaces of anode wires and the interval between anode and cathode surfaces so as to respectively have different space position resolving powers with respect to different directions. CONSTITUTION:The wire intervals of anode wire surfaces are set to values different, for example, in X- and Y-directions in order to have space position resolving powers respectively different with respect to different directions and the intervals between the anode surfaces 8, 9 having different wire intervals and respective cathode wire surfaces 2, 10, 11 are set to the proper interval values corresponding to the wire intervals. For example, the gaps between the anode surface 8 and the cathode surfaces 2, 10 are made narrow and the gaps between the anode surface 9 and the cathode surfaces 10, 11 are made wide. By this constitution, an electric field gradient equal in both wires in X- and Y-directions is formed and a equal gas mu-factor is obtained. Even with respect to oval charged particle beams expanded differentially in X- and Y-directions, the shapes and positions of beams can be measured at a proper wire interval with the proper space position resolving power corresponding to the expanses of the beams in the respective directions and this method is economical.

Abstract: PROBLEM TO BE SOLVED: To suppress the time width of a spike voltage, and prevent step-out and half of a brushless motor. SOLUTION: Flowing of an armature winding current of a brushless motor 4 is changed over by position detecting signals A, B, C, detecting the armature 4a of the brushless motor 4.

When the time width is at least a specific value, the on time width of the present chopping drive is decreased by a specific time, the present on time width is made equal to the upper limit time width, the present number of revolution is made equal to the upper limit number of revolution, and the detected motor driving current is made equal to the upper limit motor driving current value.  Also when the time width of the spike voltage does not exceed a specific value, the on time width of the present chopping drive is decreased by a specific time, and a motor voltage is lowered, by compared results of the present on time width, the present number of revolution and the motor driving current with the upper limit time width, the upper limit number of revolution and the upper limit motor driving current value. The control circuit 11 calculates and updates the above specific values for every position detection. The specific values are calculated by the position detection interval time × 25/360.
