Title: Color demodulator for color television signal
Inventor: WASHIJIMA NORIYUKI
IPC: H04N9/66
Filed: 1978-05-30
Abstract: PURPOSE: To simplify the IC-implementation of a demodulation circuit by eliminating the need to adjust a color synchronizing detection function and delay time by using a charge transfer element for the delay line of a color demodulator for color TV signals using a PLL system.  
     CONSTITUTION: At the time of the color demodulation of a color TV signal using a PLL system, a chrominance signal from terminal 11 is supplied to phase inverter 21 to obtain chrominance signals which are mutually 180° out of phase, and both the signals are applied to sampling circuits 24 and 28 for color difference signals, where sampling operations are carried out by utilizing sampling pulses from pulse generators 25 and 36. At this time, a chrominance signal in phase with the modulation axis of the color difference signal from inverter 21 is applied to 1H delay lines 22 and 30, where it is delayed a half the odd number times a subcarrier frequency close to a 1H period by making use of clock signals from generators 25 and 26; and outputs of delay lines 22 and 30 and those of circuits 24 and 28 are applied to summing arithmetic circuits 23 and 29, where the 1H-delayed color difference signal is mixed with the non-delay signal, thereby eliminating the color error in a scanning period.

Title: Rotation transmission device of woven fabric-winding roll
Inventor: KUWABARA MASAICHI
IPC: D03D49/20
Filed: 1994-03-09
Abstract: PURPOSE:To prevent the generation of winding irregularity by uniformizing a torque transmitted to a winding roll, in a device in which the rotation of a member on the driving side is transmitted to a woven fabric-winding roll on the driven side with a friction force between disks on the driving side and on the driven side. CONSTITUTION:The first disk 11 connected to the driving side, the second disk 15 connected to the winding roll, and a pressure-receiving member 5 rotation-fixed to the first disk 11 are coaxially disposed in a face-to-face arrangement. One of the disks is elastically pressed to the other disk to generate a friction force between both the disks, and the pressure force is supported on a pressure-receiving member 5. The rotation of the first disk 11 is transmitted to the second disk 15 by the action of the friction force to rotate a winding roll 4, and an elastic member is arranged between the pressure-receiving member 5 and the disk faced thereto. Even when the flatness degrees of the cooperated disks are ununiform to localize the surface contact state of the disks, the elastic member is elastically deformed in response to the localization of the contact state. Consequently, the cooperated disks are rotated, while tilted the pressure direction, and the localization of the surface contact state is thereby not caused.

Filed: 1981-04-30
Abstract: PURPOSE:To produce a plastic container wherein a warp or distortion would not happen, by cooling the inside of a plastic container immediately after the molding so that the inside and outside of the container are simultaneously cooled to exclude their temperature difference. CONSTITUTION:A synthetic resin material is injection molded into a rectangular plastic container 1 the upper part of which is open and has ribs 3 extending outward from the peripheries of the opening, and the container 1 is placed to fit on a rack 2 with the opening down. A limit switch 7 is pushed by the rib 3, and therefore a valve of a nozzle 5 that is interacted with the limit switch 7 is opened to blow cooling air to cool the inside of the container 1. After the cooling, when the container 1 is removed from the rack 2, the limit switch 7 is returned, and the valve of the nozzle 5 is closed to stop the blowing of the cooling air. Thus, as the inside and outside of the plastic container immediately after the molding are simultaneously cooled, a container for example a storing vessel under a floor wherein the preciseness of the dimensions is high, and there is no warp or distortion can be obtained.
