Title: Toner for electrophotography
Inventor: ISHIDA TOSHINAO
IPC: G03G15/08
Filed: 1989-02-03
Abstract: PURPOSE:To prevent the degradation in image density by making the number of kinds of different kinds of external additives the same in both toners for supply in the initial period and for replenishment and making the positive electrostatic chargeability of the external additives in the toner for supply in the initial period stronger than the positive electrostatic chargeability of the toner for replenishment. CONSTITUTION:The toner for supply in the initial period and the toner for replenishment are formed by adding the external additives having a charge control function on the surface of toner granular materials. The toners have at least one kind of the different kinds of the external additives which vary in kinds between both the toners and the number of the kinds of the different kinds of the external additives in both the toners is the same. The positive electrostatic chargeability of the different kinds of the external additives of the toner for supply in the initial period is stronger than the positive electrostatic chargeability of the toner for replenishment. The electrostatic charge quantity of the toners in the developer in a developing device shifts stably from the initial period of copying to the copying of repeated copying operations after the initial period of copying. The copying with stable copying densities is thus executed.

Title: Endless belt driving device
Inventor: OOGURO TADAFUMI
IPC: G03G21/16
Filed: 1984-02-16
Abstract: PURPOSE:To reduce the shaking speed of a belt in the width direction by obtaining the corrected value of the siding speed of a belt, determining the quantity of deviation to determine the deviating position, and judging the deviating position abnormal when it is beyond a defined range. CONSTITUTION:When a photosensor S1 is turned on due to the first zigzag movement of a belt 1, a control part makes a zigzag-movement correcting roller deviate in a direction to be corrected, by a define quantity. Then, as a photosensor S2 is turned on, the roller is made deviate by twice the defined quantity in the opposite direction, and the trend of deviation is obtained from the difference in siding speed between both deviations, to carry out initial stage setting for the quantity and position of deviation. After that, the quantity of deviation is corrected in such a way that the siding speed to right and left is made equal while that the quantity of deviation is gradually reduced. In this case, it the deviating position of the zigzag-movement correcting roller is beyond a proper range, it is judged abnormal and the unit is shut down. Due to this construction, the shaking speed of the belt in the width direction can be suppressed small while preventing the damage of the belt due to an abnormal deviation.

IPC: B63B35/53
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To control the shaking of an end part in a large-scale floating body without receiving any influence of a tide level. SOLUTION: This is a shaking controlling method of a large-scale floating body, which is made up so as to control the vertical shaking of a floating body end 2 with the resistance of dynamic water pressure acting on both upper and lower surfaces of a horizontal plate 5 after connecting this horizontal plate 5 to be situated the depth of water, where wave force is decreased, to the end part 2 of this large-scale floating body 1 floated and moored onto the sea surface 3. In this connection, the dynamic water pressure is not produced to such a slow movement as a tidal change and thereby the floating body follows in a free state.  In addition, a chained weight in length reaching a seabed 4 is hung down from the end part 2 of the large-scale floating body 1 floatably moored onto the sea surfaces 3 even at high tide as well as in time of maximum shaking, and thereby underwater weight (w) of the chained weight is made so as to be increased or decreased with the vertical shaking of the floating body end part 2, and thus this shaking is controlled by imparting such a load as reverse in the shaking direction to the floating body end part 2.

Title: Reproducing device for disk record
Inventor: MAEDA SATORU
IPC: G11B9/06
Filed: 1983-02-21
Abstract: PURPOSE:To prevent the decrease in the sensitivity of a tracking error and focus error detecting signal, etc. by providing a circuit for converting the voltage signal detected by a photodetecting part of an optical pickup to an average DC voltage, a comparator for taking out the differential component between the average DC signal and a reference signal and a means for controlling the quantity of a light beam in accordance with the output signal from said comparator. CONSTITUTION:Boltage signals Pa-Pd are supplied to a matrix circuit 19 and are also supplied to a DC voltage converting circuit 24. The circuit 24 forms an average DC voltage VD and outputs the same to a differential amplifier IC3. The amplifier IC3 compares the voltage VD and a reference voltage VS and outputs the result thereof as an error correcting voltage VC. The voltage VC corresponds to the decrease in the outputs of the signals Pa-Pd, and when said voltage is added to the output voltage VM from an MD voltage detecting circuit, the quantity of the light beam radiated from a laser light emitting device 15 increases in accordance with the voltage VC and therefore the quantity of the reflected light to be irradiated to a photodetector 16 is returned to the normal value.
