Title: Dephosphorization process
Inventor: OHASHI NORIO
IPC: C02F1/28
Filed: 1985-04-08
Abstract: PURPOSE:To remove phosphoric acid ion for a long period at high efficiency in a process for removing phosphoric acid ion utilizing an aluminium compd. by reactivating a particulate material contg. Al with Al salt and adding the waste liquid of the reactivation to the feed water as the Al compd. to be used for the process. CONSTITUTION:Water contg. phosphoric acid ion is passed through a packed layer of particulate material contg. Al such as activated alumina, etc. in the presence of an Al compd. (e.g. AlCl3) and under 3-8.5pH. The packed layer is washed by spreading intermittently with upward stream in the midway of water passing. When the particulate material contg. Al is deactivated, it is reactivated by allowing it to contact with an Al salt such as AlCl3, and the waste liquid of the reactivation is added to the feed liquid as the Al compd. As the result, effective dephosphorization is performed at high percentage of removal for a long period. Separate treatment of the reactivation waste liquid is unnecessary. Thus, effective utilization of resource is realized.

Title: High voltage generating circuit
Inventor: FUJINOBU YASUHIRO
IPC: H04B10/00
Filed: 1984-04-13
Abstract: PURPOSE:To reduce the loop time constant of an automatic gain control circuit by using a DC/DC converter which produces the negative output voltage of a fixed level, the 1st pnp transistor TR whose emitter is connected to the earth and the 2nd pnp TR whose base is connected to the collector. CONSTITUTION:The input voltage of a DC/DC converter 9 is fixed, and the output voltage of the converter 9 is fixed at the constant negative voltage -V0. When the DC voltage is applied to an input terminal 10, a current corresponding to said DC voltage flows to a transistor TR11. At the same time, the voltage drop is produced at a resistance 13. Then the base voltage of a TR12 is fixed at a level that is increased from the voltage -V0 by an amount equal to the voltage drop of the resistance 13. Therefore the output voltage shifted by an amount equivalent to the voltage passed through an emitter follower is produced at an output terminal 15 by connecting a load 18 to the terminal 15. In such a way, the output impedance can be reduced extremely since an emitter folloer is used at an output part. This an reduce sufficiently the time constant of a high voltage generating circuit.
