Filed: 1979-02-26
Abstract: PURPOSE: To permit the obtainment of EI and CI spectra easily as well as better operativity and shorten measuring time by performing exchange synchronously with sweeping.  
     CONSTITUTION: When the data processor 11 gives a sweeping repeat command signal to the sweeper 15, the exciting power source 14 sends forth a magnetic field sweeping signal, when the measuring mode is turned to EI mode. Receiving a sweeping finished signal of EI mode from the sweeper 15, the data processor 11  gives the EI to CI exchange signal 18 to the valve controller 13. By the signal 18,  the valve V 4  is closed and the valve V 3  is opend to supply reacting ion to the ion  source 7 and EI mode is turned to CI mode. Since sufficient exchange time from EI  to CI or vise versa is approx. 1 second the sweeper 15 waits for the time and then  starts sweeping and the spectrum of CI is obtained. And, receiving the repeated  sweeping finished signal 17, the valve controller 13 is restored to EI state.

Title: Welding device for producing electroseam steel pipe
Inventor: SAWADA KINGO
IPC: B23K13/08
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To keep working frequency of a protection circuit low, restrain reduction of operation rate of a welding device, and restrain reduction of product yielding even when a semi-conductor is used for an inverter element by installing plural pairs of contact chips. SOLUTION: Two or more contact chips 4, which are parallely and electrically connected, are arranged in a circuit of a welding device. Since two contact chips 4 are rarely lifted at a same time, momentary release of a circuit caused by lifting of the contact chips 4 can be prevented. That is, a prevention circuit built in a converter control circuit and an inverter control circuit is not actuated. A pressing means is used, wherein plural elevatable bar elements are installed in a presser block electrically connected to a resonance circuit 14 and the contact chips 4 are adhered to a tip of the bar element. Thereby, pressing is secured and non-contact frequency to a steel plate end is reduced. Also, occurrence of arc is reduced, resulting in improvement of a product quality.

Filed: 1992-01-09
Abstract: PURPOSE:To nun a filter for a long time without causing filter membrane clogging by filtering raw water with a two-layer filter medium consisting of filter cloth and filter membrane and washing and regenerating the filter cloth that can be easily washed. CONSTITUTION:A lot of filter plates 3 which form a filter bed in the recessed shape on both the faces are freely movably arranged in parallel along a guide rail. A filter membrane 8 in the shape of a sheet is spread on the filter bed of the filter plate 3 and filter cloth 9 is installed so that it may cover the filter membrane 8. An original liquid is fed to a filter chamber whose inner face is constituted of the filter cloth 9 between the filter plates 3 and is filtered by the filter membrane 8 to take out it after its coarse impurities are captured by the filter cloth 9. Since the original liquid filtered by the filter membrane 8 is passed through cake formed on the filter cloth 9 face when it is filtered by the filter cloth 9 to give it cake filtration, the filter membrane 8 does not clog for a long time. When the filter cloth 9 clogs, it is easily regenerated by opening the filter plates 3 to give it washing, etc.
