Title: Method and apparatus for encrypting and decrypting digital multiple sounds in television broadcasting
Inventor: GERAN ROSU
IPC: H04N7/167
Filed: 1991-03-20
Abstract: PURPOSE: To provide a method and device for encryption of digital multi-sound in television broadcast and its decoding. CONSTITUTION: A transmission source 1 applies a digital signal including sound information to an NICAM generator 2, which formats the signal and gives the result to an encryption unit 4, in which the resulting signal before it is sent to a receiver. The receiver is provided with a decoding unit 5. A transmitter side adds a pseudo random sequence to a digital signal to encrypt the signal. The receiver side reproduces the original signal through similar processing. A pseudo random sequence generator generates the pseudo random sequence. The sequence is controlled by a control word, generated at random at the transmitter side and changed at a proper time interval. The control word is encrypted and sent to the receiver and decoded thereat and fed to a pseudo random sequence generator of the receiver.

Title: Mos integrated circuit device
Inventor: AKAZAWA TAKASHI
IPC: H03K19/0948
Filed: 1983-05-13
Abstract: PURPOSE:To attain the high-speed rise of the input signal of a CMOS inverter circuit up to the level of power supply voltage to reduce the power consumption of the inverter circuit and then to prevent the generation of latch-up of a CMOS circuit by providing an MOSFET which receives the output signal of the CMOS inverter circuit and performs a positive feedback operation. CONSTITUTION:When the input signal IN of a ratio type inverter IV1 is set at a high level, a driving MOSFETQ2 is turned on with a p-channel MOSFETQ5 turned off respectively. When the signal IN is changed to a low level, the FETQ2 is turned off to charge up the input capacity of a CMOS inverter IV2 by a working current supplied from a load MOSFETQ1. When the output signal OUT exceeds the threshold voltages of the MOSFETQ5, the MOSFETQ5 is turned on to form a positive feedback loop which flows the charge-up current to said input capacity. As a result, it is possible to shorten greatly the time T' when both MOSFETQ3 and Q4 of the IV2 are turned on. Therefore the through current ID flowing continuously between both MOSFETQs is also reduced greatly.

Filed: 1981-05-30
Abstract: PURPOSE:To prevent cavitation and improve suction performance, by arranging the sense of a prerotating vane installed at an inlet port of a pump impeller so as to cause it to be directed to the flow direction of fluid naturally. CONSTITUTION:When a pump impeller 4 is rotated upon pump operation prerotating vanes 9 and 10 being installed in the pump impeller 4 freely for rotation of its own are also rotated around a pump shaft 3 with the same speed as the pump impeller 4, and the prerotating vanes 9 and 10 are rotating to the extent where the resistance is lowest. Therefore, fluid receives the prerotation by means of friction force and form resistance produced by the prerotating vanes 9 and 10 and is formed in a stream line, at the same time it receives pressure rise by centrifugal force, successfully riding on the pump impeller in rotation and having pump's suction performance improved in consequence. Even when the direction of flow varies due to the changes in a rate of flow, the prerotating vanes 9 and 10 are always able to match the rotation of fluid and the pump impeller 4, in conformity with the flow direction, so that improvement in pump's suction performance can be much expected.

Title: Aggregate used for processing structure of radioactive waste
Inventor: ISHIZAKI KANJIRO
IPC: G21F9/16
Filed: 1993-04-09
Abstract: PURPOSE:To safely process radioactive waste over a long period of time by constituting aggregate used for a processing structure with cement clinker. CONSTITUTION:pH indicates an important factor in guarantee of long term safety of storage of a radioactive waste processing body. In a case where pH is high, a metal-made element is corroded at low speed, damage of reinforced concrete is delayed at this rate and long term safety of storage is increased due to rich durability. A degree of solubility wherein a radioactive nuclide is dissolved in aqueous solution is low and the radioactive nuclide is effectively prevented from spreading and scattering in ground water. Ca(OH)2 determining pH of cement is comparatively quickly lost in cement paste. Conversely, in the case of cement clinker-made aggregate, a speed wherein Ca(OH)2 is produced is higher than another speed wherein Ca(OH)2 is dissolved and lost and residue concentration is heightened. Accordingly, if cement clinker is used as the aggregate, a cement structure is held high pH over a long period of time and safety is secured.
