Title: Image and sound transmission system, transmitter, receiver and method therefor
Inventor: TAKEI HIROFUMI
IPC: H04N19/423
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To improve sound quality in the case of low-speed transfer in a spread spectrum system. SOLUTION: In the transmission mode of a low transfer rate, a transmission control circuit 32 reads out the images stored in an image buffer memory 16 to a synthesis circuit 26 for 1/4 field and transmits them by 1/4 each in a one- field period. Sound is stored in a sound buffer memory 24 for four fields, read out to the synthesis circuit 26 altogether in an one-field period and transmitted. Thus, even when an obstacle is present between a transmitter and a receiver, the omission of sound data is prevented.

Title: Carrier for electrostatic latent image developer
Inventor: ISODA TETSUO
IPC: G03G9/113
Filed: 1985-03-08
Abstract: PURPOSE:To enable the formation of a stable image of high quality by coating the surface of a carrier with silicone resin contg. an organotin compound and electrically conductive fine powder. CONSTITUTION:The surface of a carrier is coated with silicone resin contg. an organotin compound and electrically conductive fine powder. The silicone resin may be silicone varnish, alkyd modified silicone varnish or epoxy modified silicone varnish. A proper quantity of electric charges having desired polarity can be easily provided to a toner by changing the amount of the organotin compound as a curing catalyst in the resulting silicone resin layer. A usable low resistance substance is an org. substance such as carbon black or an inorg. substance such as boride, carbide, nitride, oxide or silicide. Thus, a stable image of high quality can be formed without wastefully spending the toner.

Title: Video signal encoding method
Inventor: TAWARA KATSUMI
IPC: H04N19/152
Filed: 1990-02-26
Abstract: PURPOSE:To generate a quantization picture data of a proper data quantity at all times by making a quantization step size rough quantity value when power of the picture data is too excessive in the case of quantizing the picture data converted by inter-frame coding. CONSTITUTION:A quantization control unit 36 discriminates whether or not a macro block type is of inter-frame coding and whether or not macro block power MBP is larger than a prescribed threshold level. When the result is affirmative, since the MBP of the difference data is large, the effect of extreme deterioration onto the picture quality of a decoded picture is not caused even when the signal is quantized by rough quantization step size to some degree and sent. Then the quantization control unit 36 sets the quantization step size QNT to the most rough value, that is, an upper limit 31 when the macro block is subject to discrete cosine transformation by a conversion encoding circuit 29. Thus, the differential data is sent with comparatively less data quantity.
