Title: Synchronizing method for output of more than one image forming station in multicolor printing system by single pathand multicolor press
Inventor: DAGURASU II UETSUBU
IPC: H04N1/113
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To perform the accurate registration of an image to color separation by sensing the speed of a photo-responsive member when the photo-responsive member passes a second image station to form the second electric signal showing the same. SOLUTION: The developing devices 10D, 12D, 14D, 16D provided on the downstream side of respective image forming stations develop the electrostatic latent image formed on an image forming region as the result of the exposure of a light detection belt 18. Next, the sufficiently developed color image is transferred to an output sheet. In full-color operation by a single pulse, the belt 18 is driven in a processing direction (X-direction) by the servo motor 23 connected to a drive roll 24. The servo motor 23 receives a signal from an ESS 30 to control the speed of the light detection belt 18. When the image forming region passes under the image forming station 10, a first image is formed on the surface of the belt 18.

Abstract: PROBLEM TO BE SOLVED: To provide a data communication equipment which does not need a private facility and which uses a power line with extensibility by installing a power line connection means and a signal processing means converting signals among a line connection means, a telephone/FAX means and the power line connection means. SOLUTION: When an incoming call arrives from a line wire, a line connection part 103 controls a line such as the close of the line. A telephone/FAX function part 104 sets a channel by an indication from a control part 105 after the call with the line wire is established. In the case of the call with a slave machine, the channel is set to a signal processing part 106 and sound is inputted to the signal processing part 106. The signal exchanged in the signal processing part 106 is actually overlapped with a power line 101 by a power line connection part 107 and is sent to the power line 101 through a power plug 108. The signal passing through the power line 101 as the channel is inputted to the power line connection part 110 through the power plug 116 of the slave machine.

Title: Thermosetting composite racket and manufacture thereof
Inventor: TAKAHASHI YOSHIMASA
IPC: A63B49/10
Filed: 1992-12-02
Abstract: PURPOSE:To obtain a racket for sport, which is excellent in resistance to shock and vibration attenuating property, by a method wherein substantially non- continuous and non-twisted thermosetting matrix fibers are blended with reinforcing fibers having same properties with a specified ratio while a racket frame is formed by a blended fiber thread produced by winding and covering the blended fibers with a prescribed amount of thermosetting matrix fibers of the same kind. CONSTITUTION:Thermosetting matrix fibers are blended with reinforced fibers with the blending degree of 20% or more. Substantially non-twisted and non- continuous fibers are employed. Further, 1-10wt.% of thermosetting matrix fibers of the same kind as the blended matrix fibers are wound around the blended fibers to cover them and provide them with textile workability. When the amount is higher than 10wt.%, the trace of winding and covering remains in the molding process thereafter or the distribution of the reinforcing fibers becomes insufficient. Obtained blended fiber thread for composite is changed into blades, for example, through textile work while the reinforced fibers are oriented into the reinforcing direction of a racket to place them a mold, then, the frame for a racket is formed by heating and pressing them.

Title: Position detecting device for unmanned vehicle
Inventor: NOMURA MASAKATSU
IPC: G01C21/04
Filed: 1987-12-21
Abstract: PURPOSE:To measure the position and speed of the unmanned vehicle with high accuracy by providing an optical system sensor to the vehicle body and processing detection signals based upon the movement and radius of the arc. CONSTITUTION:The pattern of a road surface 80 is detected by video detection parts 30A and 30B through optical systems 20A and 20B and inputted to a microcomputer 90. The sum of products operation is executed by an input value and a set pattern stored in a ROM 93. The movement distance obtained by said arithmetic operation is differentiated to find the speed. The movement distance is calculated from the radius and variation angle in the traveling direction while the vehicle moves on the arc. Further, when the position is detected at a period much smaller than the motion of the vehicle, a change in the direction of the vehicle is found from the difference in movement distance measured value in one period of a processing part 90 and the position is found while it is considered that the vehicle travels with the mean value of the change in the period. Consequently, the accuracy of the position and speed measurement is improved.

Abstract: PURPOSE:To eliminate a trouble and to prevent the generation of artificial miss by automatically adjusting the phase of a current to flow to a focus coil in order that the phase relation of a horizontal pulse voltage and the current to flow to the focus coil can be made into a necessary phase relation. CONSTITUTION:A phase difference between a horizontal synchronizing signal and the current to flow to focus coils LR, LG, and LB is detected, and by changing the capacity of a variable capacitor C2 according to the phase difference, the phase of the current to flow to the focus coils LR, LG and LB is automatically adjusted in order that the phase relation of a horizontal pulse voltage (a) obtained from a horizontal output circuit and the current to flow to the focus coils LR, LG and LB can be made into the necessary phase relation. Consequently, in the manufacturing stage of the product, a necessity for an adjusting person to adjust the phase to flow to the focus coils does not exist. Thus, the trouble can be eliminated, and even the artificial miss such as an adjustment miss cannot be generated.

Title: Charging method of sealed type lead storage battery
Inventor: KATAYAMA KAZUTAKA
IPC: H02J7/00
Filed: 1990-11-27
Abstract: PURPOSE:To protect a battery from an overcharge and to extend its cycle life by measuring time required to reduce the charging amount from the first set value to the second set value after the battery reaches a specific battery voltage, and carrying out a constant voltage charge and a constant current charge, according to the measurement value. CONSTITUTION:At first, a battery is charged by a constant current, and converted to a constant voltage charge after it reaches a specific set voltage, and the time measurement is started. When the charging voltage is reduced gradually, and the time T to reach a specific current value is within the set time T0, a constant voltage charge is carried out. On the other hand, when T is higher than T0, a constant voltage charge is carried out until a specific time T5, and after that, the charging current is converted to a minute current to carry out a constant current charge. Consequently, regardless of the unevenness of old and new records of individual batterys, the battery can be protected from an overcharge or a heat running-away, and the cycle life is extended.

Title: Ink jet recorder
Inventor: ARA YOJI
IPC: B41J2/185
Filed: 1989-12-14
Abstract: PURPOSE:To reduce power consumption required for driving of pump in a recovery unit, to shorten the record recovery time and to improve cost performance by performing control for increasing torque of a driving means upon dead lock of the pump constituting the recovery unit. CONSTITUTION:Drive source (pulse motor) for a recovery unit is operated with a pulse rate No when a pump operates normally without causing dead lock, whereas it is operated with a pulse rate N1 upon occurrence of dead lock. Consequently, when the motor is initially driven with the high pulse rate N0 and a home position switch 54 is turned ON, following recovery control is carried out under control with pulse rate N0. If the home position switch 54 is not turned ON, it is judged that the pump is in dead lock and the pulse rate N1 is lowered to N1. When dead lock is eliminated and the home position switch 54 is turned ON, the pulse rate is returned to the higher rate N0 and the pump 28 is driven. By such arrangement, recovery sequence is finished earlier and recording speed is improved.
