Title: Method of and apparatus for measuring water content in foundry sand
Inventor: SHIBATA TSUTOMU
IPC: G01N27/04
Filed: 1981-07-28
Abstract: PURPOSE:To improve the measuring accuracy by detecting current between electrodes when foundry sand to measure water content is compressed with two electrode members. CONSTITUTION:A weight 22 is moved properly to adjust and set the pressing force of a cylindrical member 11 made up of a conductor. When foundry sand to measure the water content is fed through a chute 29, it enters a groove defined by a cylindrical member 6 made up of a conductor and a disc members 7 and 8 made of an insulator at a lower end opening of the chute 26 and transferred in the direction of the cylindrical member 6 rotates while compressed under a fixed pressing with the cylindrical member 11 to increase the density thereof. Under such a condition, when a voltage is applied between the cylindrical membes 6 and 11, current runs according to the water contained in the foundry sand. Thus, the intensity of the current is detected to calculate the water content.

Title: Transmitting system of television system
Inventor: IIJIMA MASAHIKO
IPC: H04N7/36
Filed: 1981-07-31
Abstract: PURPOSE:To realize the coding with high efficiency, by sampling a TV signal with a sub-Nyquist frequency that is lower than a double of the highest frequency of the TV signal band, higher than the highest frequency and equal to 1/2 odd-fold level of a horizontal synchronizing frequency. CONSTITUTION:The energy is concentrated to the frequency of an integer-fold value of a horizontal synchronizing frequency fH for the spectrum distribution of a TV signal. The digital signal obtained by giving an A/D conversion to the TV signal is sampled with a sampling frequency fS and through a coding circuit 2 of the transmitting side 7. The frequency fS is set lower than a double of the highest frequency fC of the TV signal band and higher than the frequency fC and at the same time set at 1/2 odd-fold level of a horizontal synchronizing frequency fH. For this sampled spectrum distribution, the folded noise is caused within a signal band ranging from a frequency (fS-fC) to fC. This noise, however, is suppressed by a filter. The output of the circuit 2 undergoes the predictive coding through an inter-frame predictive coding circuit 3 and with the 2-frame preceding sampling output signal and is then transmitted to be reproduced at the receiving side.
