Filed: 1993-12-27
Abstract: PURPOSE:To adjust the refreshing operation between coders. CONSTITUTION:A down-sampler 3 generates a reduced video signal (existing TV signal component) from an HDTV signal from an input terminal 1. A 1st coder 7 applies high efficiency coding to the video signal and the coded signal is fed to a multiplexer 9 and decoded and the result is fed to an UP-sampler 11. A subtractor subtracts a low resolution component of the HDTV signal from the sampler 11 from the HDTV signal to generate a high resolution component of the HDTV signal and it is fed to a 2nd coder 13. The coder 13 applies high efficiency coding to the received signal and gives the coded signal to the multiplexer 9. The multiplexer 9 multiplexes the received signal and an output from the coder 7 and outputs to a buffer memory 15. A coding rate controller 17 obtains information of buffer occupancy quantity of the memory 15 to control the coding rate of both the coders 7, 13. Both coders 7, 13 are composed of a motion compensation inter-frame prediction coder but implements refreshing at a different phase or period.

Abstract: PURPOSE:To maintain the amplitude of an output signal even during high-speed rotation and to make it possible to prevent the decrease in S/N and dropouts by controlling a light-source driving means in response to the frequency of the output signal of a photodetector or an otherwised detected speed. CONSTITUTION:In a photodetector 5, the output signals from photodetector elements 8 and 9 are amplified in a signal processing circuit 11. Then, the signals are inputted into an F/V conversion circuit 13. Here, the output voltage which is increased in correspondence with the increase in frequency of a pulse signal (c) is outputted into a light-source driving circuit 14. A driving current for a light source 1 is controlled with a control voltage obtained by appropriately adding the frequency-proportional voltage to a constant-quantity command voltage (a) with the circuit 14. The amount of the output light from the light source 1 is increased with the increase in output frequency of the pulse signal. Therefore, the amount of the light from the light source 1 is increased, and the amplitude of the output signal is maintained. The decrease in S/N and dropouts can be prevented. The load for the light source 1 during the low-speed rotation does not become excessive, and the decrease in life of the light source 1 is prevented.

Title: Memory control circuit
Inventor: MURANAKA TSUNEYOSHI
IPC: G06F12/08
Filed: 1987-12-28
Abstract: PURPOSE:To obtain a high hit rate with a small memory capacity by using a four-way set associate cache to constitute a memory control circuit. CONSTITUTION:When a CPU tries to read data though data does not exist in tag comparators 1-4, a cache controller 28 detects a miss to access a main storage. This control is performed by signals 51, 52, and 54, and a signal 53 is the ready signal of the main storage device. A write controller 17 receives the signal 53 to write data and the address in one of a proper bank out of comparators 1-4 and one of RAMs 5-8 by an output 39 of an LRU 36. When four banks are filled up and an address other than addresses of banks is accessed, the oldest bank out of four banks is determined by the controller 36. When a hit occurs, the bank at this time is stored in the controller 36 to always update the state. At the time of writing data by the CPU, update is determined by a hit or a miss of memories 5-8. By this constitution, the access time is shortened.

Title: Production of resin particles
Inventor: SHIOZAKI MASAYA
IPC: G03G9/087
Filed: 1990-11-28
Abstract: PURPOSE:To obtain resin particles having superior electrostatic chargeability, durability and moisture resistance without causing flocculation of core particles by polymerizing monomers including a monomer having a positive charge in an aq. medium and carrying out alkali treatment. CONSTITUTION:Monomers including a monomer having a positive charge in an aq. medium are polymerized and alkali treatment is carried out. The resulting polymer has high hygroscopicity because of its positive polarity but it is made hydrophobic by alkali treatment and exhibits superior moisture resistance. Since core particles and fine particles used have electric charges of opposite polarities in the aq. medium, when they are mixed and dispersed in the medium, the fine particles stick electrically to the surfaces of the core particles and tight sticking is attained by heating and melt-sticking the fine particles to the core particles in the electrically sticking state. Resin particles having superior electrostatic chargeability, durability and moisture resistance can be obtd.
