Title: Data transmission circuit
Inventor: TAKEDA TOSHIYUKI
IPC: H03K19/096
Filed: 1989-01-25
Abstract: PURPOSE:To prevent malfunction of the title circuit even when a period for refreshing a data is long or a threshold level of a feedback transistor(TR) is small by using a source voltage of the said TR as a voltage with a lower level than a power voltage when the feedback TR compensating a level notch is turned off. CONSTITUTION:The title circuit is provided with a transfer gate 1, an inverter 2, a 4th TR Q4 of opposite conduction type and a voltage switching section 3. A power voltage VDD is supplied to a source of the 4th TR Q4 in the voltage switching section 3 when a P-channel TR Q6 is turned on with a low level output data OUT and a low level voltage VDD-VT5 (VT5 is a threshold level of TR Q5) is supplied when the output data OUT is at a high level and an N-channel TR Q5 is turned on. Thus, the TR Q4 is not turned on before the output data level is dropped larger than a level VT5+VTP (VTP, is a threshold level of TR Q4)and no malfunction takes place.

Abstract: PURPOSE:To prevent a traverse signal from contaminating a focus servo circuit and making the focus servo malfunction by inserting peak value detecting circuits and an adding circuit into the focus servo circuit. CONSTITUTION:Circuits 22A and 22B to detect and hold the positive and negative peak values of a focus error signal with a prescribed time constant and a circuit 23 to add the outputs of the hold circuits are inserted into the focus servo circuit.

Consequently, the traverse signal St is removed and the focus error signal is obtained even during a traverse. Thus, the malfunction of the focus servo is eliminated.

Title: Broadcasting satellite
Inventor: TAKIMOTO YUKIO
IPC: H04H20/00
Filed: 1987-01-28
Abstract: PURPOSE:To completely match frame synchronizing phases at a ground station, by sending a frame synchronizing signal generated in a satellite to a ground transmission station with a carrier different from that of a television video signal. CONSTITUTION:A reference frame synchronizing signal applies a signal processing such as modulation, frequency conversion, and amplification. etc., on the carrier with a frequency different from that of a TV signal, and sends it from each transmission antenna to ground. The reception part of the ground station demodulates the TV signal and the reference frame synchronizing signal sent via the satellite, and detects the time difference (t) of the frame synchronizing signal, and after supplying a delay time corresponding to the time difference, transmits it from a transmission antenna to the satellite. When the TV signal sent from the ground transmission station is received with the antenna 1i of the satellite. and it arrives at a switch matrix 4, the signal whose phase is matched with that of another TV signal can be obtained, therefore, no step out is generated even when the TV signal between beams is switched.

Title: Electrophotographic device
Inventor: UENO HIROSHI
IPC: G03G21/06
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic device capable of transferring a fine toner image to paper as it is and suited to realize high resolution and high printing quality by providing an optical discharge device and a corona discharge device impressing corona the polarity of which is reverse to toner between a developing device and a transfer device. SOLUTION: The toner 7 developing-processed by the developing device 2 is transferred to the paper 6 by the transfer device 5. The toner 7 after developing exists inside the electrostatic latent image of a photoreceptor 1 and is partially scattered to a part out of the electrostatic latent image as the potential of the photoreceptor 1 at a non-exposure part is discharged by an erasing lamp 3. Thereafter, only one layer of the toner 7 is electrostatically charged to have the reverse polarity by a pretransfer corona 4, so that the toner scattered to the part out of the electrostatic latent image is not transferred to the paper 6. However, the toner 7 inside the electrostatic latent image is easily transferred to the paper 6 because restricting force by the electrostatic latent image is eliminated. Thus, the fine toner image is transferred to the paper 6 as it is.

Title: Recording or reproducing device
Inventor: OSANAI EIJI
IPC: G11B17/34
Filed: 1987-01-30
Abstract: PURPOSE:To obtain a stable slide contact between a disk and a head by providing slant surfaces corresponding to the shape of a disk which is changeable in its shape to be positioned respectively on a surface opposite to the disk as a positive pressure generating surface for generating a positive pressure on the upper stream side and the lower stream side respectively from the head in the rotational direction of the disk. CONSTITUTION:On the surface of a stabilizing member 51 opposite to the disk 1, a 1st slant surface 51a for generating a positive pressure is protrusively formed adjacent to a recessed part 51c on the upper stream side in the direction of A, while a 2nd slant surface 51d with a narrow width for generating a positive pressure is formed protrusively between the recessed part 51c and a recessed part 51b on the lower stream side in the direction of A of the recessed parts 51. At the time of rotating of the disk 1, a positive pressure caused by an air flow between the slant surfaces 51a and 51d and the disk 1 respectively is generated, so that the disk 1 is pressed to be apart from the stabilizing member 51, and hence the pushed-out disk 1 is pressed to the head 4 accordingly. Although the positive pressure is decided depending upon the shape of a gap, this shape of the gap is approximately constant due to the slanting surfaces 51a and 51d in the correspondence of the deformation of the disk 1. In this way, any contact to be made between the positive pressure generating member 51 and the disk 1 is prevented, and hence an extremely stable and excellent slide contact condition is secured between the disk 1 and the head 4.
