IPC: C09D13/00
Filed: 1992-05-01
Abstract: PURPOSE:To obtain a solid correction agent capable of rewriting without repelling even water base ink by incorporating N-fatty acid acyl amino acid having a specified structure or alkali salt thereof, water or the mixed solvent of a water-mixable organic solvent and water, water soluble and/or water dispersive film forming resin and dye or pigment of white color. CONSTITUTION:A solid correction agent is obtained by incorporating N-fatty acid acyl amino acid shown in a formula I (RCO- shows fatty acid residual radical) or alkali salt thereof, water or the mixed solvent of a water-mixable organic solvent and water, water soluble and/or water dispersive film forming resin and dye or pigment of white color and/or color similar to the quality of paper as an essential component.

Title: Freezer
Inventor: SHIMURA KAZUHIRO
IPC: F25B1/00
Filed: 1994-07-08
Abstract: PURPOSE:To ensure a predetermined freezing capability by employing a non- azeotropic mixture refrigerant, disposing an accumulator on the suction side of a compressor, and providing a heater for heating the refrigerant flowing into the accumulator. CONSTITUTION:A non-azeotropic mixture refrigerant sometimes stays in an accumulator 6 in a liquid state upon operation starting of a freezing and upon heating operation. In this case, a gas or liquid composition ratio of a non- azeotropic mixture refrigerant circulated in the freezer is changed. Against this, the amount of the liquid refrigerant in the accumulator 6 is detected by a float switch 17, and when the amount exceeds a predetermined amount, an opening valve 11 is opened to send a discharged refrigerant into a heater 8. Accordingly, the refrigerant sucked in the accumulator 6 is heated to raise temperature in the accumulator 6. Hereby, the refrigerant higher in a high boiling point composition ratio that has been a liquid state gassifies and is sucked into the compressor 1 and is further circulated. With this operation, refrigerant pressure is lowered.

Title: Pattern generator
Inventor: DEGUCHI MASASHI
IPC: G09G5/24
Filed: 1977-12-27
Abstract: PURPOSE: To reduce the capacity of a memory and generate easily arbitrary patterns different in a size by combining a general-purpose P-ROM, a shift register and a counter circuit.  
     CONSTITUTION: The storage start address of character and symbol patterns is set in pre-set counter 2, and pattern data from P-ROM 1 addressed by this address enters output shift register 3 which is shifted successively according to external clock signals. The output of register 3 outputs data of every dot of a pattern through output buffer 4. Counter 5 counts the number of shift times of register 3 and issues a signal by which contents of counter 2 is counted up by +1, and P-ROM 1 outputs pattern data of the next address to register 3. As a result, pattern data is stored in P-ROM so that pattern data cannot have space surplus as shown in the figure, and therefore, the capacity of the memory can be reduced, and special patterns can be generated.

Abstract: PURPOSE:To miniaturize the titled device by arranging a printed circuit board in a way that its thickness direction is made in parallel with a recording face in the moving locus of a holding member while being bent the U-shape in the broadwise direction. CONSTITUTION:The flexible printed circuit board 65 bent in following to the movement of a pickup body 7 holding the objective lens and its servo drive mechanism and supplying a drive current to the servo drive mechanism is bent in the U-shape in the thickness direction and arranged within the moving locus of the body 7 so that its thickness direction is made in parallel with the recording face of a recording medium. In arranging the board 65 in this way, the load exerted by the board 65 with respect to the movement of the body 7 is suppressed lower and the reproduction/recording of information is applied smoothly. Since the recording face of the recording medium and the broadwise direction of the board 65 are made in parallel, the board 65 is not largely bent while being swollen in a direction at a right angle to the recoding face and the miniaturization in the direction of right angle, that is, the direction of height of the optical information recording and reproducing device is easily miniaturized.

IPC: H05K1/11
Filed: 1989-06-19
Abstract: PURPOSE:To give directivity to surplus solder after squeeze and thereby to facilitate the flow thereof and to connect and form a solder layer uniformly by a method wherein pads for surface mounting which are provided on the surface of a prescribed area of a wiring board are constructed in a shape wherein an end face thereof in a prescribed direction has one projected point. CONSTITUTION:Pads 1a' for surface mounting which are provided on the surface of a prescribed area of the main body 1' of a printed circuit board are constructed in a shape wherein an end face thereof in a prescribed direction has one projected point, that is, in the shape of a curved surface or the like. When the printed circuit board is immersed in a molten solder bath and pulled up therefrom, solder is blown off by an air knife, while the surface of the board is squeegeed. On the occasion, the side of the end face shaped in the curved surface and having one projected point is set on the terminal side of the squeegeeing operation. By this method, surplus solder is given directivity and made to flow with ease. Thereby a protuberant residue of the solder on the surface of each pad 1a' for surface mounting is prevented or reduced, while a necessary solder layer is connected and formed uniformly.

Filed: 1987-06-25
Abstract: PURPOSE:To prevent a wow and a flutter from being generated in reproduction by recording a high frequency signal on a control signal and controlling the period speed of a capstan motor so that the reproduction frequency of the high frequency signal in reproduction is constant. CONSTITUTION:In recording operation, a signal coincident with the frequency of the vertical synchronizing signal of a video signal is generated by a control signal generator 13 and an extremely high frequency signal is generated by a pilot signal generator 15, applied to an AC head 10 through a superposing circuit 16 and a recording amplifier 11c, and recorded on a specific track on a tape 1. When reproduction is performed, on the other hand, a capstan motor control part 23 controls the capstan motor 21 so that the period of the 0-cross point of the input superposed signal is constant. Consequently, a wow and flutter component generated in recording is canceled and no wow and flutter noise is generated in reproduction.

Filed: 1985-07-19
Abstract: PURPOSE:To prevent malfunction by transferring the control to a stand-alone equipment only when a stand-alone transfer request is issued from both of a remote line concentrator and the stand-alone equipment. CONSTITUTION:A stand-alone equipment 4 connects a master station 1 and a remote line concentrator 2 by a PCM line 3 and operates the remote line concentrator 2 as an independent station for trouble of the PCM line 3. In this case, the remote line concentrator 2 is switched and connected to the stand- alone equipment 4 to operate the remote line concentrator 2 as an independent station only when the stand-alone transfer request is issued from both of the remote line concentrator 2 and the stand-alone equipment 4. Thus, the stand- alone transfer request which is issued from the remote line concentrator 2 or the stand-alone device 4 by program runaway of a processor or the like is ignored to prevented malfunction.
