Title: Chrominance signal reproducing circuit capable of eliminating phase distortion
Inventor: HARENO MICHITAKA
IPC: H04N9/64
Filed: 1983-09-01
Abstract: PURPOSE:To eliminate phase distortion of a chrominance carrier signal by producing a signal having a phase opposite to that of phase distortion included in the chrominance carrier signal and mixing them based on the chrominance carrier signal. CONSTITUTION:An output of the chrominance carrier signal amplified at a band amplifier circuit 5 is divided into two; one is fed to a mixing circuit 4 and the other is fed to an amplitude modulation circuit 2. On the other hand, a locking oscillator 1 is driven by a frequency component twice a reference subcarrier fs formed by a reference subcarrier generating circuit 7 to form a signal of 2fs. The output is fed to the amplitude modulator 2 and the 2fs signal is subject to amplitude modulation by the chrominance carrier signal. Then only the lower side band component of the modulation output is fed to the mixing circuit 4 through a band filter 3. Since the phase distortion of the chrominance carrier signal is cancelled by the signal having opposite phase, the distortion is eliminated in this way.

Title: Image forming device
Inventor: SATO MITSURU
IPC: G03G15/08
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To stably transfer toner by previously detecting blocking of the toner in a screw pump for transferring recovered toner or fresh toner as the gas flow of a gaseous mixture with a gas and controlling the operation of the screw pump of a gas supplying means, based on information of the detection. SOLUTION: The gas supplying means 6 supplies the gas for fluidizing the toner to the screw pump and this screw pump fluidizes/transfers the recovered toner recovered by a cleaning means or the fresh toner as the flow of the gaseous mixture with the gas. At this time, a blocking previously detecting means 7 detects blocking of the toner in the screw pump in advance and a controller 20 controls the operation of the screw pump or the gas supplying means 6, based on the information of the detection. Thus, blocking of the toner, etc., can be prevented, while the degree of freedom to select a toner transfer path is secured, to maintain transfer force of the toner and stably transfer the toner, without giving damage to any parts.

Title: Liquid crystal cell forming monodomain
Inventor: KONDOU KATSUMI
IPC: G02F1/1339
Filed: 1982-09-16
Abstract: PURPOSE:To align liquid crystals in a monodomain, by using an interface effect between the liquid crystals and a spacer. CONSTITUTION:Any spacer is usable so long as it can control orientation of liquid crystals and can retain the form of them, and a polymer, such as polyethylene, is used. The entire liquid crystals are heated to convert them into an isotropic phase, temp. gradient is maintained spatially, then they are gradually cooled from the interface between the spacer and the liquid crystals, and the liquid crystal phase is uniformly grown. At ths time, each of the liquid crystal molecules tends to align in parallel to each other so as to minimize energy caused by intermolecular action, resulting in growth of a uniformly aligning domain. When the uniformity of alignment lowers as the liquid crystal becomes farther from the interface, it is better to lessen the distance (d) between the spacers. A memory effect can be given by applying it to strong dielectric liquid crystals.
