Title: Filtering and concentrating method and device
Inventor: YAGISHITA AIZABURO
IPC: B01D29/62
Filed: 1993-02-08
Abstract: PURPOSE:To shorten switching time between a filtration process and a backwash process and to increase the operation efficiency of a filter by only opening/ closing a discharge valve with a crude liquid pump operated to continuously switching between the filtration process and the backwash process. CONSTITUTION:When a filtration process is continued, that is, when a crude liquid pump 5 is operated with a discharge valve 6 closed, a suction pump 7 is operated to evacuate a waste liquid tank 4. When the discharge valve 6 is rapidly opened, a crude liquid in a crude liquid tank 2b is sucked into a waste liquid tank 4 through a discharge liquid pass D and the crude liquid tank 2b is temporarily evacuated. Then a filtered liquid in a filtered liquid chamber 2c in the pressure accumulated state backflows to the crude liquid chamber 2b through a filter medium 2d and cake on the filter medium 2d is removed to fall into the crude liquid in the crude liquid chamber 2b. When a discharge valve 6 is closed after a prescribed time, for example, a time of about 10sec has elapsed, the baskwash process is finished to restore the filtration process. On the other hand, the cake settles and is accumulated in the bottom part of the crude liquid chamber 2b and is sucked and discharged as waste liquid into a waste liquid tank 4 in the next backwash process.

Filed: 1995-02-08
Abstract: PURPOSE: To provide an information card and a card reader which make it difficult to read ID information and generate a copy and are made lightweight and reduced in power consumption. CONSTITUTION: On the information card 1, 1st ID information is recorded magnetically and 2nd ID information is stored electrically.

A coincidence signal is outputted when the 1st ID information and 2nd ID information match with each other. Consequently, the information card 1 is obtained which is hardly copied and made lightweight. Further, the information card 1 sends the 2nd ID information by utilizing electric power induced by a radio wave sent from the card reader 12, which inputs the 2nd ID information after taking in the information card 1, so the electric power supplied to the information card 1 may be small and the power consumption is reducible.

Abstract: PURPOSE:To manufacture an optical fiber with a small transmission loss without any damage by radiation by using as a raw material a silicon compound resolving at a relatively low temperature and by using composite silica glass obtained at a low composition temperature with a little structure defection for a high-refractive-index part. CONSTITUTION:To a burner of a quartz glass pipe, O2 gas is flowed together with H2 and (or) D2 as flame accelerating gas to put them in flames, and an organic compound such as Si(OC2H5)4 resolving at a relatively low temperature or hydride such as SiH4 is led into the flames together with the carrier gas to bring about flame reaction. Thus, impalpable powder of silica glass containing an OH group and (or) OD group slightly is obtained and then applied onto a target in rotation to form a lamination on the target with the glass fused, making silica glass as a high-refractive-index part. This is united with a low-refractive-index part of silicone resin, etc., into a fiber, so that the aimed optical fiber is obtained.
