Title: Squid magnetic flux meter
Inventor: INOUE ATSUKI
IPC: H01L39/22
Filed: 1992-11-30
Abstract: PURPOSE:To reduce the scale of a low-temperature side circuit which is turned into superconducting state without especially increasing the number of signal lines between the lowtemperature side circuit and a high-temperature side circuit. CONSTITUTION:A SQUID magnetic flux detection part 21 converts input magnetic flux to the difference (p-q) between the number of positive pulses of an UP/DOWN UD and the number of negative pulses. The negative pulse of the UP/DOWN UD is inverted to a positive pulse by a negative polarity inversion circuit 22, the positive pulse in a positive period is maintained to be the positive pulse, the positive pulse in a negative period is eliminated, and then the positive pulse is generated at the pulse-missing part in the negative period by a compensation signal generation circuit 23 and a positive compensation conversion circuit 26, the signal is counted by an UP counter 24A to obtain {p+(n- - or + )}, and then (p-q) is calculated from it and a known n by a compensation circuit 34. Since the counter 24A may be counted up, thus reducing the circuit scale per bit to be half that of the UP/DOWN counter.

Title: Back-filling method and device
Inventor: KIYAMA KATSUJI
IPC: B65G53/16
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To improve filling density and save labor for filling work by using coarse earth for a back-filling material and filling it in prescribed places while delivering through a hose by air pressure. SOLUTION: Granular or lump objects that roll easily including sand and gravel or crushed stone are used as a back-fill material because sand may clog a hose and be blown up. The Sand and gravel of about 5 to 40 mm in grain size is suitable. Of feeders 5 that feed sand and gravel into a hose 3, a screw feeder 8 can feed a fixed amount of sand and gravel and a rotary valve 9 makes such feed intermittent. These regulating functions of both machines help prevent clogging. As a device to send forth a strong current of air, a blower 1 and a compressor is used, thereby allowing the hose to be extended freely and a back-filling material to be delivered to a back-fill site by wind pressure. Thus it is easy to execute work in a site where transporting a back-filling material is difficult.
