IPC: B41F31/00
Filed: 1990-05-08
Abstract: PURPOSE:To prevent the temperature of an ink from rising by the Joule heat produced upon current application by providing a coating means with an ink cooling means. CONSTITUTION:A coating means consists of an ink carrying roll 1 and a coating roll 9 and the two units of ink cooling means are provided consisting of water supply devices 11 and 13, pipes 12a, 12b and 14a, 14b and water passageways 1a and 3a, respectively. The ink carrying roll 1 is provided with a thermistor 15 to serve as a temperature sensor. The thermistor 15 is changed in resistance with a change in the temperature of cooling water and this resistance is converted into voltage E2 through an electric source E1 and a resistor R1 and this voltage is compared with a reference voltage E0 by a comparator C. An output produced by the comparator C as a result of its comparison activates a relay R to open and close through a relay driver RD, thereby controlling an electric source E3 to actuate a pump 15e between on and off conditions. In this way the supply of the cooling water is controlled and the temperature of an ink 2 is maintained at a predetermined value.

Title: Expansible chute for loader
Inventor: HIGASHINAKA KOUICHI
IPC: B65G11/14
Filed: 1977-09-30
Abstract: PURPOSE: To provide a chute which is made of truncated-cone-shaped short pipes and used to load a scattering matter and easy to replace abraded parts.  
     CONSTITUTION: The inner diameter of a short pipe 21 on the uppermost truncated- cone-shaped short pipe 4 under a drop-down port 1a of a conveyor 1 is smaller than that of the short pipe 4. A hard elastic material is lined or a hard alloy material is brazed on the inside surface of the short pipe 21. The scattering matter dropped down from the conveyor 1 goes down while colliding against the inside surface of the short pipe 21. Since the inner diameter of the short pipe 21 is smaller than that of the truncated-cone-shaped short plpe 4, the scattering matter goes down almost in the center of the short pipe 4. When the short pipe 21 is abraded, only the short pipe 21 can be replaced

Abstract: PROBLEM TO BE SOLVED: To make it possible to paste a non-woven fabric to a base material under the condition that the liquid absorbing force of the non-woven fabric is held unchanged by a method wherein the specified thick liquid absorbing force-holding non-woven fabric is pasted to the base material through a thermoplastic resin so as to hold the specified liquid absorbing force in the non-woven fabric. SOLUTION: As the material of a non-woven fabric, the fiber of various chemical and natural materials is properly selected in response to the liquid to be absorbed. The thickness of the non-woven fabric is set to be 0.05-0.6 mm. In addition, as a base material, polyester or the like is used. The thickness of the base material is properly selected in response to its object and normally set to the extent of 9-1,000 μm. The pasting together of the base material and the non-woven fabric is carried out by melt-extruding a thermoplastic resin between them. In this case, the thermoplastic resin, the melting point of which is lower than that of the base material and which is suitable for extrusion, such as polyethylene or the like is used. After the pasting, the non-woven fabric is set to hold the liquid absorbing force of 0.005-0.05 ml/cm<2> .  Thus, the lowering of the liquid absorbing force of the non-woven fabric due to the pasting to the base material can be prevented from occurring.

Title: Odd-even field decision circuit
Inventor: KANAZAWA YASUNORI
IPC: H04N5/08
Filed: 1978-09-27
Abstract: PURPOSE: To make decision on odd and even fields by a simple constitution when a video signal is recorded by VTR, by processing a composite synchronizing signal of the video signal by a counter, gate, etc.  
     CONSTITUTION: Once triggered by a composite synchronizing signal formed of equivalent pulses and a vertical synchronizing signal, monostable multivibrator 1 with a fixed time constant generates fixed gate pulses to open AND gate 2. As a result, counter 3 counts equivalent pulses extracted from the composite synchronizing signal passing through gate 2. When the count value reaches a fixed number, counter 3 triggers monostable multivibrator 4 to close AND gates 7 and 8 by the output of multivibrator 4 passing through differentiating circuit 5 and inverter 6. Therefore, field discrimination equivalent pulses are extracted by gates 7 and 8 as high-level signals in accordance with odd and even fields right after a fixed number of equivalent pulses in the composite synchronizing signal and inverted composite synchronizing signal applied to gates 7 and 8, so that decisions on odd and even fields can be made by simple constitution.
