Title: Back projection type screen
Inventor: SAITO YOSHIHIRO
IPC: G03B21/62
Filed: 1987-06-17
Abstract: PURPOSE:To hold high fineness and to attain maximization by forming a screen by adjacently arranging many lenticular lenses, which are thinly and lightly formed, in parallel and burying or fixing a wire having high-tensile strength in the border parts of the respective adjacent lenticular lenses. CONSTITUTION:The high-tensile strength wire 5 is buried or fixed in the parts adjacent to the lenticular lens 3a, which is thinly and lightly formed. And both ends of the wire 5 are fixed to a strong screen frame 6 whose rigidity is high so that the screen is supported in a plane by given tension. The lenticular lens 4a having the same constitution as the lens 3a is fixed to the back surface of the screen. Thus, the thickness of the material of screen can be reduced and the fineness of a video can be improved by decreasing a sag and scattered light caused by the change of the temperature of environment, etc., so that the maximization can be enhanced.

Filed: 1986-06-27
Abstract: PURPOSE:To inexpensively provide a recorder simple in construction, small in size and thin in form, by arranging recording elements, e.g., heat generating elements on the back side of a smooth plate formed of a material having a high thermal conductivity and serving also as a reflector for a liquid-crystal display part. CONSTITUTION:A thermal head 5 provided on the side of a lower surface 4B of a smooth reflector 4 is provided with heat generating elements 50-1-50-N, the number N of which is equal to the number of column patterns 24-1-24-N. When recording, a voltage is applied selectively between driving electrodes 51-1-51-N and a common electrode pattern 52 to cause the heat generating elements 50 to generate heat, thereby recording on a recording paper 8. The smooth reflector 4 is formed of a material having relatively favorable thermal conductivity, such as aluminum, so that a heat accumulation phenomenon is prevented from occurring in the thermal head 5 constituted of the heat generating elements 50. With the reflector formed of a material having a favorable thermal conductivity and with the recording elements arranged on the opposite side of the reflector to constitute a recording part, a recorder can be realized which is extremely thin in form, small in size, light in weight and low in cost.

IPC: B41J13/076
Filed: 1988-06-17
Abstract: PURPOSE:To rapidly cope with jamming and to certainly perform the manual insert-feeding of paper by setting the greater part of the peripheral surface of a paper feed roller to a high friction coefficient surface while setting a part thereof to a low friction coefficient surface and providing the low friction coefficient surface at the contact position with a friction plate in a stand-by state. CONSTITUTION:In the case of cassette paper feed, when a paper feed roller 10 is rotated, the uppermost paper received in a cassette 40 and the surface of the paper feed roller 10 generate slippage through a low friction coefficient surface 15 and, from the point of time when a high friction coefficient surface 13 moving later begins to be brought into contact with the uppermost paper, only the uppermost paper is fed in a predetermined direction. In the case of manual insert paper feed, manual insert paper is brought into contact with the high friction coefficient surface 13 first of all and comes above the uppermost paper received in the already inserted cassette 40 and only the manual insert paper can be certainly fed in a predetermined direction along with the rotation of the paper feed roller 10. The paper feed roller 10 stops in a stand-by state after one revolution regardless of the paper in the cassette 40 and the manual insert paper and, even when jamming is generated, the surface of the paper feed roller 10 in contact with jamming paper becomes the low friction coefficient surface 15 to make it possible to easily pull-out the jamming paper without tearing the same.

Abstract: PURPOSE:To reduce the hardware quantity by synthesizing the conference call signal with an analog signal and transmitting them after converting them into digital signals. CONSTITUTION:The call signal sent from a general telephone 10 is converted into a digital signal by a digital line circuit 20 and supplied to an analog 3-person call trunk 50 via a digital network 30. Thus the digital signal is converted into an analog signal by a decoder 101 and supplied to an analog synthesizing part 2 via a hybrid 102 and then to hybrids 202 and 302 via capacitors C1-C3. The 4-wire transmission side outputs of both hybrids 202 and 302 are converted into digital forms by coders 200 and 300 and sent to digital line circuits 21 and 22 via the network 30. The circuits 21 and 22 convert the digital signals onto analog signals and transmit them simultaneously to general telephones 11 and 12. Thus the talking is possible among three persons.
