Title: Wet type electrophotographic device
Inventor: NAKAJIMA YUTAKA
IPC: G03G15/10
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To obtain the function of recycling liquid toner by recovering a liquid mixture of a liquid developer and a prewet liquid, remaining on the surface of a developing roller and separating liquids subject to recycling for the liquid developer and the prewet liquid. SOLUTION: A prewet device 13 coats the surface of a photoreceptor 10 with silicone oil having a specific viscosity. The developer is supplied to a developing device 14, in such a manner that the developer is carried from a toner puddle, while spreading thin, by an applicator roller. Thus, a toner layer is formed on the developing roller. Then, the positively charged toner is supplied to the photoreceptor 10, in accordance with the electric field between the developing roller and the photoreceptor 10, so that the toner is stuck to the exposed part of the charged photoreceptor 10.  The liquid mixture of the liquid developer and the prewet liquid remaining on the surface of the developing roller is recovered by a recovering means and the liquids subject to recycling for the liquid developer and the prewet liquid are separated from the liquid mixture recovered by the recovering means by a separating means.

Title: Video recorder
Inventor: INOUE TAKESHI
IPC: H04N5/92
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To attain writing at an optimum recording rate by decoding coded data, conducting again variable length coding so as to record decoded data onto a recording medium and recording the re-coded coded data to the recording medium. SOLUTION: A recording medium management section 4 reads data having already been stored in a recording medium 5 and an auxiliary recording medium 6. A recording medium management section 4 gives read data to a decoding section 8, where the data are once decoded. The decoding section 8 gives the decoded data to a coding section 7, which encodes the decoded data at an obtained rewriting rate. The recoding medium management section 4 rewrites the data whose recording rate is converted to the recording medium 5 again. The rewriting is made to a head address of the recording medium 5 for video recording by means of overwrite. Since the data are rewritten in the recording medium 5 in this way, the entire program can be recording on the recording medium 5 at the same recording rate.

Abstract: PURPOSE:To control the number of revolution of a motor efficiently by comparing the number of revolution of the motor and a set value, determining applied voltage to a stator winding and controlling an oscillating circuit so that the applied voltage and output voltage from a rectifying circuit are equalized. CONSTITUTION:Output voltage corresponding to the number of revolution of a motor from a F/V conversion circuit 29 and reference voltage are compared by a comparison circuit 36 on starting, and voltage applied to a stator winding is elevated by differential voltage between both voltage, thus facilitating starting. When the number of revolution of the brushless motor 25 is made higher than set resolution, output voltage from the comparison circuit 36 rises, and a control circuit 40 controls an oscillating circuit 15, output voltage from a rectifying circuit 16 is lowered and the number of revolution of the brushless motor 25 is brought near to the number of revolution set when the output voltage is made higher than voltage based on output voltage from the rectifying circuit 16. Likewise, when the number of revolution of the brushless motor 25 is made lower than the number of revolution set, output voltage from the rectifying circuit 16 is elevated, and the number of revolution of the brushless motor 25 is brought near to the number of revolution set.

Filed: 1989-09-07
Abstract: PURPOSE:To reduce an area to be occupied by a terminal part, and to make a slider compact and light in weight by sharing the terminal part of a slider type thin film magnetic head for which two head elements are symmetrically arranged. CONSTITUTION:In the thin film magnetic head equipped with two head elements 2 and 3, terminal parts 41 and 42 are provided commonly for the respective head elements so that the operation of one head element can be made ineffective (for example, dielectrics 51, 52, 61 and 62 for pulling out the coil of one head element can be cut off).

When the head element 2 is not used, the dielectric parts 51 and 52 are cut off and the terminal parts 41 and 42 are made exclusive for the element part 3. Thus, only by parallelly providing the totally two element parts in two lines, the occupied area of the whole terminal part can be reduced and a whole slider 1 can be made compact and light in weight.

Title: Contour correcting device
Inventor: TANAKA TOMOAKI
IPC: H04N5/208
Filed: 1992-08-31
Abstract: PURPOSE:To detect and reduce the impulsive noises due to the picture element defects, etc., of a solid state image pickup element and to emphasize and correct the necessary contour signals without erasing them. CONSTITUTION:A noted point of an image is outputted together with the signal amplitude of a group of approximate points approximating to the periphery of the noted point in a two-dimensional way when a video input signal (a) is temporarily held. A noise detecting circuit 5 detects the impulsive noise of the noted point based on the two-dimensional correlation of an original image. A contour signal control circuit 7 controls the amplitude of the contour signal (b) generated at the noted point or inverts the polarity concurrently with the control of the amplitude of the signal (b) in accordance with a control signal (d), i.e., the detection result of the circuit 5. Then the signal (a) is added to a time-delayed signal. Thus it is possible to prevent such a case where the impulsive noise is emphasized by mistake or the necessary image contour information is erased by mistake for elimination of the noise.
