Inventor: TANAKA MASAHITO
IPC: C09K23/52
Filed: 1989-10-17
Abstract: PURPOSE:To obtain an intermediate sheet capable of eliminating color contamination efficiently and with excellent initial coloring properties and high light-fastness by using a water dispersed liquid for a coloring agent consisting of specific metal salts of substituted salicylic acid with the particles of the coloring agent which are ground in a wet condition to such as extent that the average particle diameter is not significantly reduced. CONSTITUTION:A water dispersed liquid for a coloring agent is obtained by the following process: a coloring agent with a softening point of higher than 30 deg.C which is composed mainly of substituted salicylate as shown by formula I is dissolved in an organic solvent. Then this solution is emulsified and dispersed in an aqueous polyvinyl alcohol solution with more than 70% of saponification degree and more than 500 of polymerization degree in a heated or a non-heated state. After that, a water dispersed liquid obtained by heating the dispersed liquid and removing an organic solvent by distillation is subjected to a wet fine-grinding process on condition that the average particle diameter of the coloring agent is not reduced beyond the limits of 10%. In formula I, R1, R2, R3 and R4 are a hydrogen atom, a halogen atom, a 1-9C alkyl group or phenyl group; M is magnesium, calcium, zinc, aluminum, iron, cobalt, nickel or the basic ion of either one of these substances.

Title: Waveform distortion eliminating device
Inventor: ITO SHIGEHIRO
IPC: H04N5/21
Filed: 1989-10-18
Abstract: PURPOSE:To extract selectively a video signal before and after waveform distortion processing without stopping the operation by implementing the changeover of insertion and input/output connection of a matching means with respect to the input side of a waveform distortion elimination power consumption system and keeping the video signal input independently of the state of a switch means for the waveform distortion elimination processing system. CONSTITUTION:Switch means 46, 48 are switched as required and either a video signal subject to waveform distortion elimination or a video signal not subject to waveform distortion elimination is selectively outputted to an external opposite device. The inputted video signal is inputted to a waveform distortion elimination processing system 40 independently of the operation of the switch means 46, 48 and the operation of the elimination processing is continued. Thus, the video signal before and after the elimination processing is extracted selectively without stopping the function of the waveform distortion elimination processing system 40 and the video signal before and after the elimination processing to confirm the ghost elimination effect is switched without giving effect onto the ghost elimination processing function.

Filed: 1994-11-04
Abstract: PURPOSE: To output a sound under outputting from a speaker at present from a remote controller by providing an input/output voice switching part at a VTR or the like and performing the FM transmission of a signal, which is different from that sound, from a voice source designated by the remote controller. CONSTITUTION: When an operation button 19 provided on a sound remote controller 2 is operated, a microcomputer 20 transmits a remote control code corresponding to the button operation to a remote control transmission part 21. A remote control signal reception part 9 catches an infrared remote control signal and reports its code to a microcomputer 10. The microcomputer 10 instructs switching to the correspondent mode to an input/output voice switching part 3. As a result, a designated audio signal is supplied to an external stereo amplifier 15, the speaker is rung and on the other hand, the designated audio signal is supplied to an FM transmitter 6. Since the sound remote controller 2 receives a radio wave transmitted from an antenna 7 through an antenna 23 and an FM receiver 22, the sound different from the sound of the main speaker can be heard by an earphone 25.

Title: Board fixing device
Inventor: KOJIMA ITSUO
IPC: H05K5/00
Filed: 1989-10-17
Abstract: PURPOSE:To make it possible to fix a board swiftly with a simple mechanism by adopting a mechanism which moves a board pressing plate in parallel with a mounted circuit board and hold the board against a lift spring force. CONSTITUTION:A board holding plate 13 is opened based on a link support section 15 as the pivot. A mounted circuit board 12 is placed thereon. When a handle 131 is lowered, link plates 113a and 113b are rotated against the force of a lift spring 14 after the plate 13 comes in parallel with the board so that the plate 13 move downward, keeping parallel with the mounted board 12. As a result, a pressing member 132 presses the board 12 downward that a connector pin 123 may be brought into contact with a contact pin 231. When the upper part of a lock bar 134 passes through the lower part of a lock pin 211, the pin 211 is thrust by the force of a spring 212, thereby preventing the bar 234 from floating up and fixing the plate 13. It is, therefore, possible to fix the board readily and detect electric operation in simple mechanism.

Abstract: PURPOSE:To shorten a scanning time without applying any impact to a scanner by varying the preliminary run distance of the scanner according to set magnification. CONSTITUTION:When the set magnification corresponds to reduction, a mirror base MB1 starts at a point A1 shifted according to the reduction magnification on the basis of its home position. When a motor 38 is driven to turn forward, it attains to a set feed speed V1 and a point B, then reaches a rear end E at the same speed and begins to reverse, and decrease to 0 at an overrun position F to make a return. Then, the motor attains to a return speed V3 at a point D, and is brought under reversing control at a control point C1 corresponding to the reduction magnification to stop at the point A1. When a life size mode is set, the start position of the base MB1 moves to a point A2, a feed speed V2 is obtained at the point B, and a return is made similarly at a return speed V3; and a brake is applied at a brake point C2 and the motor stops at the point A2. When an enlargement mode is set, the operation is performed similarly; the start position further moves beyond A2 and the return speed is V3 as well.

Filed: 1994-11-07
Abstract: PURPOSE: To prevent a high frequency current from increasing by adding a load current and a compensating current to each other, and converting it into DC separately for each order of the harmonics, and comparing it with a set value on specified level. CONSTITUTION: An adder 18 adds a load current IL and a compensating current Ia to each other, and a DC converter 19 operates each order of the harmonics, and converts it into DC separately for each order of harmonics, and outputs DC signals Pa-Pd. And, comparators 20a-20d compare the DC signals Pa--Pd with a set value Pr separately for each order of the harmonics, and if it is less than the set value Pr, this turns into an usual operation mode. On the other hand, if the enlargement of a harmonic current ILh occurs, for example, the thirteenth DC signal Pd gets over the set value Pr, and a three-terminal analog switch 17d is switched over to the side of a changeover contact v.  As a result, out of the harmonic currents ILh, only the thirteenth order of each- order-of-harmonic-operation part output signal are composed by each degree of higher harmonic adder 8b, with its polarity inverted, and are inputted into the adder 9. Thereupon, the harmonics increase phenomena of the concerning order is prevented.
