Abstract: PURPOSE:To ensure the good reproduction not only for the received pictures but for the  TV pictures of characters and patterns, by supplying the output of a synchronizing signal separating circuit to a vertical oscillating circuit in the form of a horizontal trigger pulse and securing the synchronism between the rise of the oscillating output pulse of the vertical oscillating circuit and the rise of the horizontal pulse. CONSTITUTION:Either one of the horizontal pulses supplied from a route led from an external video signal source 8 and a horizontal deflecting outut circuit 4 is selected by switching the interlocking switches 11 and 12. When a picture pattern produced from  a built-in signal producing circuit 9 is projected, the switches 11 and 12 are set at the (a) side. Thus the horizontal pulse given from the picture 4 is fed to a synchronizing signal separating circuit 1. Furtheroire the horizontal trigger pulse is applied to a vertical oscillating circuit 2 from the circuit 1. Then the vertical oscillating pulse is produced synchronously with the horizontal pulse, and the vertical period becomes longer then the horizontal period by an integer-fold value. The signal is produced from the circuit 9 with the synchronism secured with the horizontal and vertical pulses respectively. Then this signal is applied to a video signal output circuit 10 to project a synchronous picture.

Title: Thermally insulated fluid passage
Inventor: IWATA HIDEO
IPC: F24S10/50
Filed: 1981-12-15
Abstract: PURPOSE:To obtain a sloar heat collector of high collecting efficiency by a method wherein the titled fluid passage is formed by a bag whose upper and lower walls are made of sheet materials and the upper and lower surfaces of the fluid passage are shielded by different sheet materials leaving clearances from the latters, respectively. CONSTITUTION:A fluid passage is formed by the bag 9 whose upper and lower walls are made of sheet materials 7 and 8 and both upper and lower surfaces of the bag 9 are shielded by sheet materials 10 and 11 so that the clearances 12 and 13 isolated from outside are provided above and below the bag 9. Further, spacers 14-16 are interposed among the sheet materials 7, 8, 10 and 11 so as to keep the sheet materials at predetermined intervals, respectively, and the fluid passages thus formed are made to have a suitable degree of elasticity. Thus, in case where such thermally insulated fluid passage is used as a solar heat collector, any one of the sheet materials 10 and 11 (for example, the sheet material 10) is made transparent. As a consequence, the sunlight is applied on the sheet material 7 through the transparent sheet material 10 to thereby elevate the temperature of a heat medium flowing through the bag 9. In addition, due to the provision of the clearances 12 and 13, it is possible to prevent the radiation of heat from the upper and the rear surface of the bag 9 and to keep hot the heat medium in the bag 9.

Title: Production of paper base material from resin coated paper
Inventor: ITO IKUO
IPC: B29B17/02
Filed: 1993-08-17
Abstract: PURPOSE:To easily peel a resin coating layer by forming through-holes to one of the resin coating layers on both surfaces of a paper base material so as to reach the paper base material and allowing ketone having permeability to the piper base material to penetrate into the paper base material from the through-holes. CONSTITUTION:Through-holes are provided to the resin coating layer on the rear surface of resin coated paper 20 by a perforation die 11 moved up and down at the same speed as a drive roll 2 and a receiving stand 12 and the perforated resin coated paper 20 is guided to a liquid tank 13 filled with acetone through a feed roll 4. The resin coating surface of the resin coated paper 20 is irradiated with ultrasonic waves in the liquid tank 13 by an ultrasonic vibrator 14. During this period, the penetration and diffusion of acetone to a paper base material of the resin coated paper 20 from through-holes are accelerated. Therefore, the bonding strength between the upper and rear resin coating layer and the paper base material is weakened and the peeling of the resin coating layers becomes easy. The rear resin coating layer 21, paper base material layer 22 and surface resin coating layer 23 of the resin coated paper are respectively separated from the position of press rolls 6, 7 to be treated. Therefore, the resin coating layers are continuously and easily peeled and three layers can be independently recovered.

Title: Rotary valve of hydraulic buffer
Inventor: KASHIMA MITSUHIRO
IPC: F16F9/44
Filed: 1990-07-31
Abstract: PURPOSE:To prevent the generation of swish noise by setting the top edge part of a rotary rod opposite to an inner vacant part and setting the thin hole of a rotary valve opposite to the outer peripheral surface of the top edge surface of the rotary rod. CONSTITUTION:A rotary valve 4 is turning-operated, and a drilled thin hole 4a puts a bypass passage L into a communication state, and a piston part 2 is set into an extension/contraction cycle in which the piston part 2 gets out from the inside of a cylinder 1, and then the working oil supplied from a rod side oil chamber A flows into the inner vacant part 4b of the rotary valve 4 through the thin hole 4a of the rotary valve 4. At this time, though the working oil supplied from the rod side oil chamber A on the high pressure side is allowed to flow sharply into the inner vacant part 4b on the low pressure side, the sharp flow of the working oil into the inner vacant part 4b collides with the top edge part 5b of the rotary rod 5, since the top edge part 5b of a rotary rod 5 is set close to the inner vacant part 4b. Accordingly, in the inner vacant part 4b, the direct collision of the sharp flows of the working oil is prevented, and the generation of swish noise is prevented.
