Title: Video signal recording and reproducing system
Inventor: OKAMURA HIDEO
IPC: H04N5/93
Filed: 1978-12-28
Abstract: PURPOSE: To reproduce uniform good-quality pictures throughout all regions of a disc by controlling a band gain control circuit of reproducing signals according to reproducing positions in respect to reproducing of video signals of the optical video disc.  
     CONSTITUTION: The reproducing signal from disc 15 is converted to an electric signal by photo detectors 8a and 8b and is inputted to band gain control circuit 101 through adder 9. Meanwhile, the transfer quantity of disc 15 obtained by detection part 110 and the position of optical transfer material I (the part inside the one- dotted broken line) obtained by detection part 112 are converted to DC voltages by circuits 111 and 113 respectively and are added by adder 114 to obtain a DC voltage corresponding to the reproducing position of disc 15. Next, the gain of band gain control circuit 101 is so controlled by this DC voltage that the reproducing signal from disc 15 above may be larger for outside circumference reproducing of disc 15 than that for inside circumference reproducing, thereby compensating the reproducing signal.

Title: Excessive toner elimination device
Inventor: YAMANASHI MOTOAKI
IPC: G03G15/11
Filed: 1991-07-05
Abstract: PURPOSE:To prevent deterioration of electric current power and to improve the complication of maintenance by always carrying an electro deposited toner clod in a toner clod containing means. CONSTITUTION:The toner electro deposited on an electro deposition roll 23 is scraped off by a scraper 25, abutted to the electro deposition roll 23 along with the rotation of the electro deposition roll 23. When the toner clod is scraped off onto the scraper 25, rotation of a rotary blade 27 is started with its tip abutted to a scraper 25, the toner clod on the scraper 25 is eliminated, and the eliminated toner clod is contained in a toner tray (toner clod containing means) 26. Furthermore, the toner remaining on the rotary blade 27 is stripped off by having a tip of an elastic blade 28 abutted to the rotary blade 27 along with the rotation of the rotary blade 27, and the toner is contained in the toner tray 26. Thus, a large quantity of the toner clod is not stuck to the scraper 25, even when the device is operated for a long period of time.

Filed: 1990-06-26
Abstract: PURPOSE:To obtain a thermal recording sheet extremely well in the plasticizer resistance of a color forming part and also excellent in the heat resistance of an undeveloped color part by using oxalic ester and/or aliphatic dibasic acid ester and a specific color forming compound in combination. CONSTITUTION:A thermal recording sheet has a thermal color forming layer containing a color forming compound, an acidic substance and a sensitizer.

IPC: A47G9/02
Filed: 1993-06-11
Abstract: PURPOSE:To float the central part of the quilt to a dome shape and to fully envelope the body within the dome of the quilt by downward curving both left and right sides of partitioning cloth in a transverse direction. CONSTITUTION:The peripheral edges of front cloth 1 and rear cloth 2 are joined by means, such as sewing. The inside thereof is provided with plural pieces of the partitioning cloth 3 extending in a transverse direction apart prescribed intervals in the central part of the quilt excluding at least the peripheral edges to form many block chambers 4. Feather is then packed into the respective block chambers. The partitioning cloth 3 in the transverse direction of the central part of the quilt is formed to a shape curving downward toward the lower side by height H1 on both left and right sides and is formed to a shape decreasing gradually in the width H2 of the partitioning cloth from the central part toward the lateral sides. The partitioning cloth 3 is then sewn. The peripheral edges of the quilt exist in the lowest reference position X and the central part floats by H1. The dome shape as a whole is thus formed. The parts of the lateral block chambers 6 themselves exist in the reference position to effectively prohibit the inflow of the outdoor air. A user is, therefore, able to ensure a stable sleep without turning up of the peripheral edge parts and exposing of the body to the outdoor air.

Title: Automatic brake operation device having brake force retention device
Inventor: NAKAZATO TAKEHIKO
IPC: B60T11/28
Filed: 1986-07-17
Abstract: PURPOSE:To prevent a brake force from decreasing as a result of sudden release of a brake after a vehicle stops by providing a solenoid valve of a brake force retention device having the solenoid valve to be closed by a specified signal interposed between a pneumatic source and a brake action section with a throttling means, thereby restricting air outflow during the closing action of the solenoid valve. CONSTITUTION:Pressurized air due to a brake pedal operation is sent from a pipe 9 to a brake actuator through a pressure chamber 30 provided with a closing valve body 24 via a pipe 10. Retention of a brake force is performed by actuating a closing valve body 30 by means of a specified signal issued one second after a vehicle stops. A throttle portion 102 and a ring member 111 are arranged in a passage 103 between the pressure chamber 30 and the pipe 10 so that, when a brake pedal is suddenly released after the vehicle stops, the passage 103 is closed by the ring member 111 while leaving the passage 102 only open to prevent pressurized air in the pipe 10 from being discharged suddenly. Even if the brake pedal is released suddenly, a retained brake force can be prevented from decreasing due to sudden pressure decrease in the pipe 10 as if the brake pedal were released gradually.

Abstract: PURPOSE:To obtain an excellent electromagnetic conversion characteristic over the entire frequency band, by maintaining the coercive force of a coated magnetic layer at 300-700Oe, the residual magnetic flux density at 1,200-2,000 Gauss, the thickness at 2-8mum and maintaining the coercive force of a thin ferromagnetic metallic film layer at 500-1,000Oe, the residual magnetic flux density at 8,000-12,000 Gauss and the thickness at 50-4,000Angstrom . CONSTITUTION:A coated magnetic layer 2 is provided on the surface of a nonmagnetic substrate 1 consisting of a polyester film or the like and further a thin ferromagnetic metallic film layer 3 is formed. The coercive force of the layer 2 is required to be >=500Oe in order to obtain the sensitivity from a middle to high band and the upper limit thereof is kept at about 700Oe in order to obtain a thorough erasing characteristic. If the thickness of the layer 3 is 100Angstrom , only the high band output is stressed and produces hardly hearable sounds. If the thickness is >=4,000Angstrom , rigidity is too high and running is unstable. If the coercive force of the layer 3 is <=500Oe, the thoroughly high band output is not obtainable and if >=1,000Oe, the degaussing is not enough.
