IPC: H04L27/227
Filed: 1979-12-27
Abstract: PURPOSE:To eliminate the residual amplitude and the residual phase inclination of the carrier wave, by detecting amplitude components of the PSK modulation  wave and by controlling the bias of the multiplier by these amplitude components. CONSTITUTION:The PSK modulation wave input from A is applied to multiplier 4 and AM detector 1. AM detector 1 detects amplitude components of the PSK modulation wave, and this output is applied to bias circuit of multiplier 4 to control the bias of the multiplier according to amplitude components of the input PSK modulation wave.

Title: Electrolytic filter
Inventor: OTOME YUUJI
IPC: B01D35/06
Filed: 1993-06-18
Abstract: PURPOSE:To provide a filter where filter force is high, water passing resistance is small, and the breeding of bacteria is effectively prevented. CONSTITUTION:A filter has a construction where the 1st and 2nd metal plates 2, 3 of different ionization tendencies and insulating filter mediums 4 are placed one upon another. In the filter, when suspended matter-contg. water to be treated is passed, metal ions are discharged from one metal plate based on the difference between ionization tendencies of both the metal plates, and an electric field is accordingly caused between both the metal plates. The floating matter to be removed is electrophoretically and forcibly moved in the direction that intersects the water passing one by the electric field, allowing its contact efficiency with the filter mediums to be heightened. As a result, small water passing resistance and high filter force are obtained.

Title: Liquid feeder
Inventor: HAYASHI YOSHIAKI
IPC: B01J4/00
Filed: 1984-08-18
Abstract: PURPOSE:To prevents the dripping of a washing liquid at the tip of nozzles regardless of difference in the height among the nozzle tips, by positioning an open end of a shunt passage communicating with each nozzle below the tips of the nozzles. CONSTITUTION:After the supply of a washing water, when a valve 42 is closed and a valve 53 opened, a drain tube 54 allowed to communicate with all of supply nozzles 44-47. As the tip of a tube 54 is positioned below the tips of the nozzles 44-47, a pressure difference is generated between the surface level of a retained washing water in the tube 54 and those of residual washing waters in the nozzles 44-47, which permits the reversing of the washing water left in the tube connected to these nozzles 44-47 to a branch 43 and the washing water thus reversed flows to a receiving tank 55 from the tube 54 until a balance is reached. Thus, this prvents accidental dripping of the washing water left from the tips of the nozzles 44-47 after the pouring of a washing water.
