Title: Method and apparatus for processing signal
Inventor: MOHAMEDO SHIEIKAA SABURI
IPC: H04N19/00
Filed: 1987-12-03
Abstract: A video codec is used to reduce the bandwidth of a video signal for storage and/or transmission. To transmit an uncoded quality colour NTSC television signal in digitized form requires channel bandwidth typically 90-130 Mb/s for the signal in the composite format and 216 Mb/s for the signal in the component format. The proposed video codec achieves a reduction of the required transmission bandwidth by a factor of 2-3 by splitting the input signal into two channels, a main and a complementary channel, and by applying different coding techniques in each. In the main channel the input signal is subsampled and DPCM encoded using a fixed-rate companded quantization, whereas VWL and block coding is used to encode the complementary channel carrying the interpolation error signal. This arrangement seeks to ensure high picture quality while being easily adaptable to different transmission rates and signal formats. In bandwidth-on-demand applications the main channel can be used alone to provide a lesser quality signal, for example CATV quality at 35 Mb/s, with an attendant reduction in system complexity.

IPC: D21C9/153
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a batch or continuous process for counter-currently recycling bleaching filtrate for delignification and bleaching of a pulp. SOLUTION: The oxygen delignification of a pulp is excessively achieved to about 50% to about 76% measure by a kappa number, and on the other hand, the viscosity of the pulp is only slightly reduced within the range of about 2 to about 5 cps. The bleaching of the delignified pulp is achieved by a peroxide compound and ozone, and the pulp brightness of about 82-88 ISO can be achieved at zero level TOX content from a bleaching chemical and at zero level AOX content in bleaching effluent. High brightness of about 90 to about 92 is achieved by the addition of a very low level chlorine-based bleaching chemical. The AOX content of the corresponding bleaching effluent is <=200.  The bleaching filtrate can be recycled for using the filtrate for pulp cleaning or in an organosolv pulping process, and the pollution can be removed by typically combining extreme energy saving with chlorine-based bleaching.

Title: Hydraulic pressure converting device
Inventor: NAKAO HIROTOSHI
IPC: F15B3/00
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To perform effective operation and prevent heat generation due to power loss. SOLUTION: A first port 11 and a second port 12 are formed in a valve plate 8 for dividing pressure fluid to the suction and discharge, and the second port 12 is further divided into an inside port 12a and outside port 12b. A plurality of piston sliding holes 5 are sorted according to the holes communicated to the first port 11 and the outside port 12b and the holes communicated to the first port 11 and the inside port 12a. Thrust force works to a piston by the introduction of pressure fluid to the first port 11, resulting in the rotation of a cylinder block, and the pressure of an output port works to the inside port 12a, making torque work in the direction opposing to the rotation direction of the cylinder block. The condition to balance the rotation torque can be determined by the distribution ratio of the inside port 12a to the outside port 12b. Therefore, pressure can be boosted by the distribution ratio of the inside port 12a and the outside port 12b, and if the distribution ratio is reversed, pressure can be reduced.

Abstract: PURPOSE:To detect selectively only a fact that a variable element reaches the termination of revolution to stop the drive of a motor by providing a 1st comparator, a 2nd comparator, and a logic circuit which processes the output signals of both comparators. CONSTITUTION:The load current flowing to a motor 2 is converted into a voltage via a resistance 7, and amplified by a voltage amplifier 8. A 1st compa rator 12 detects the change of the load current of the motor 2. A 2nd compara tor 18 detects the change of the load current of the motor 2 started by a factor other than a fact that a variable element 4 reached the termination of revolu tion. Then the detection signals of both comparators 12 and 18 are inputted to a logic circuit 19 and only the change of the load current of the motor 2 due to the fact that the element 4 reached the termination of revolution is detected. Thus it is possible to stop the drive of the motor 2 after detecting only the termination of the element 4 with high accuracy and at high speed. As a result, the element 4 is never broken at the time of regulating automati cally an electronic equipment.
