Title: Deciding system of picture quality
Inventor: SONEHARA NOBORU
IPC: H04N1/00
Filed: 1981-10-12
Abstract: PURPOSE:To detect the deterioration of picture quality due to an error of a transmission line and the missing of information, by transmitting the count value of all scan lines of a screen as well as the picture signal to the receive side from the transmitter side. CONSTITUTION:The transmitting picture signal is converted into a run length code by a coder 10. The coder 10 counts the number of coded scan lines by means of a scan line counter 11 when the coding of a scan line is over. Then the count value of the scan lines on a screen which is counted by the counter 11 is added and transmitted to the receiver side after the end signal of the coding data of a screen. The receiver side receives the transmitted count value of scan lines of a screen from the transmitter side after receiving a screen. Then the count value is detected by a controller 16 and fed to a comparator 19 along with the count value of the decoded scan lines of a screen which is detected by a decoded scan line counter 18. The comparator 19 compares the difference between both count values with the threshold value 3. Thus the picture quality is decided by the difference of the comparison.

Title: Corrosion- and wear-resistant nickel based alloy
Inventor: TANAKA MORIMICHI
IPC: C22C19/05
Filed: 1978-12-27
Abstract: PURPOSE: To provide an economical, wear- and corrosion-resistant cylinder internal coating alloy by reducing Co content from Ni-Co alloy which contains Cr and B, and further adding Si.  
     CONSTITUTION: An Ni based alloy consisting of Cr; 5W10%, B; 2.5W4%, Si; 2.5W10%, Co; 5W40%, and the remaining Ni is used to coat the internal surface of cylindrical cylinder for use in, for example, plastic molding machine, by using centrifugal coating method. Co content is smaller than that of conventional alloy of the same type. The addition of Si, however, produces synergistic effect of Ni, Co, and Si, and provides a wear-and corrosion-resistance which is equal to Ni based alloy having a greater content of Co. Furthermore, the reduced amount of Co contributes to cost reduction.

Abstract: PURPOSE: To provide a compact liquid Na regeneration system for facilitated operation in a device to purify liquid Na for use as cooling material in fast breeder reactor by providing a means to control the quantity of exhaust in the regeneration system.  
     CONSTITUTION: A liquid Na purifier body 3 is connected through valve 21 to a regeneration system consisting of a degassing pot 22, a vapor trap 24, a filter 25, an electric-control type valve 31 between the filter 25 and exhausting system, a pressure gauge 32 to detect pressure in the space above the degassing pot 22. A controller 33 regulates the valve 31 in accordance with the output from the gauge 32 so as to maintain the pressure in the space above the pot 22 at a constant value. This value of pressure is set in advance, through the controller 33, to be slightly higher than the vapor pressure of liquid Na at that temperature. This sufficiently reduces the quantity of Na vapor produced from the degassing pot 22 and smoothly exhausts H 2  or other impurity. Thus, the vapor trap 24 can be made compact.
