Title: Device for retaining laminated sheet
Inventor: ASAI TOSHIO
IPC: B65H3/56
Filed: 1988-12-20
Abstract: PURPOSE:To keep the pressing force by sheet retainer claws always constant even if the height to the top face of laminated sheets is changed and correctly separate and feed the sheets one at a time by providing a guide mechanism for guiding the sheet retainer claws so as to fall by their own weight and come in contact with the topmost face of the laminated sheets. CONSTITUTION:One sheet on the topmost portion of laminated sheets 1 is rolled in between a winding roller 10 and a sheet retainer board 11 and projected out to the upper portion of the roller 10. In this condition, the winding roller 10 and sheet retainer board 11 are lifted up to lift up and transfer the topmost one sheet. At this time, the second and following sheets are retained by sheet retainer claws 9 which fall by their own weight on four corners. Thereby, the ends of the second and following sheets can be prevented from being shifted rightward. Hence, it is surely prevented that the second sheet from the topmost portion is attached to the topmost one sheet and sent out together.

Abstract: PURPOSE: To surely process digital data in plural bits independently of a transmission speed of data. CONSTITUTION: Digital data in plural bits sent in the unit of bytes are latched by a data latch section 2. It is monitored that digital full bits of digital data are confirmed to be arranged by the data latch section 2 and when all bits are arranged, the data latch section 2 sends the digital data to a D/A converter section 1 based on a control signal sent through a control line. Thus, even when transmission interval of digital data in the unit of bytes is extended because of a slow data transmission speed, analog data are surely outputted from the D/A converter section 1 without missing or error in the digital data.

Title: Video signal transmission system
Inventor: SAKATA HARUO
IPC: H04B1/16
Filed: 1988-12-19
Abstract: PURPOSE:To provide a system in practical use even after the revision of regulation by transmitting a video signal after converting to a frequency suitable for a transmission frequency and modulating further by a PN code from a pseudo noise code generator, cenverting the frequency to the one of prescribed times by multiplying by a reception signal, and demodulating it setting as a continuous sine wave. CONSTITUTION:Frequency diffusion can be performed by applying secondary modulation on a frequency modulated wave frequency-modulated by continuous level change by a PN code, and reception can be performed even when electric field strength is decreased. At a receiver, a signal secondary-modulated by the PN code goes to the frequency modulated wave of continuous sine wave in spite of the PN code by a square circuit 17, and the demodulation of the video signal can be performed by an ordinary frequency demodulator 7. In such a way, it is possible to obtain a transmission system with arrival distance in practical use even after the revision of the regulation by transmitting the video signal with a small power per band area by a spread spectrum system.
