Title: Concentration control of damping water for lithographic printing
Inventor: TAKASE MASUMI
IPC: B41N3/08
Filed: 1991-04-26
Abstract: PURPOSE:To improve the concentration control accuracy of each component in damping water by setting a control range for at least, one type of property value selected from among property values such as pH value, conductivity, refraction index, specific gravity and gas concentration which have a specific relationship with the concentration of each component in damping water, and controlling the concentration of each component in the damping water in accordance with the control range. CONSTITUTION:A tank 1 for damping water supply, a water tray 4 and a damping water feed system of feed and return lines 2, 5 for the water tray are employed. A control range consisting of one reference value and the other reference value is set for the typical property value of the concentration of each component of damping water. If any component is measured to indicate a value beyond the control range of one reference value, the component is added to the tank for damping water supply for a specified time. The frequency of adding damping water can be reduced by repeating the intermittent addition of damping water and the component until the concentration of the component reaches a value near the other reference value established as the control range. In addition, the oversupply of each component in the damping water can be eliminated by setting a wait time.

Title: Image reader
Inventor: KATO YASUO
IPC: G06T5/00
Filed: 1989-05-18
Abstract: PURPOSE:To obtain image data of a high picture quality irrespective of a state of a document image by converting the document image consisting of multivalued data into binary image data in accordance with a threshold or a half tone processing pattern determined by the maximum value and the minimum value of density of a document. CONSTITUTION:A density detecting part 17 detects the maximum and the minimum density values from inputted image data, and the maximum and the minimum density values which are detected are stored in a detected density storage part 13. A threshold/pattern calculating part 19 calculates a threshold or a half tone processing pattern being optimum for a document from the maximum and the minimum density values and sends it to a binarization/half tone processing part 20. The binarization/half tone processing part 20 converts fetched multivalued image data into binary data of black and white by scanning of a scanning unit part in accordance with the calculated threshold or half tone processing pattern. In such a way, even against a document of low constant and biased density, image data of a high picture quality can be obtained by an optimum threshold or half tone processing pattern.

IPC: G11C11/34
Filed: 1982-07-21
Abstract: PURPOSE:To prevent the unbalance of holding current of a memory cell, by using a transistor of reverse multicollector structure as a constant current source and forming the corresponding holding current of one memory cell from each collector. CONSTITUTION:A transistor (TR)Q6 is a reverse mutlicollector TR and a bias constant voltage VB is impressed to the base, and a resistor R6 is provided to the emitter. Each collector of the TRQ6 forms the holding current of one memory cell MC. A TRQ5 having four collectors forms each holding current to four memory cells. Further, the holding current is formed with a TRQ7 and a resistor R7 the same as above as to the memory cell of other row. Since the holding current of one memory cell is formed from each conllector of the TR of the multicollector structure, the holding current of each memory cell is made almost uniform by forming the collector area as a uniform value.

Title: Tape recorder
Inventor: SHIMAMURA TAKAYUKI
IPC: G11B27/10
Filed: 1981-08-10
Abstract: PURPOSE:To simplify the constitution and to make the cost inexpensive, by performing the automatic recording selection of each cassette tape of the 1st and 2nd cassette mechanisms with a commmon automatic recording selection circuit and using the changeover with one operation switch in common. CONSTITUTION:A reproduced output of a reproducing magnetic head H-1 is always applied to an input terminal of an automatic recording selection circuit E via a recording changeover switch S2-1, and the automatic recording selection circuit E is operated when a tape runs between interrecordings of a cassette tape loaded to the 1st cassette mechanism. The output is applied to the 1st cassette mechanism driving circuit G via a recording changeover switch S2-2 to change over the 1st cassette mechanism to a halt state. Thus, the automatic recording selection can be made by means of the recording changeover switches S2-1-S2-3 and a dubbing-off changeover switch S2-4. Thus, since the changeover switch can be used in common with one operation switch, the entire constitution can be simplified with reduced cost.
