Title: Running system of submergible pump
Inventor: TSUTSUI TOSHIAKI
IPC: F04B49/06
Filed: 1981-11-20
Abstract: PURPOSE:To reduce running power of pump to the necessary minimum by controllably changing over the pump driving motor from direct drive with commercial power supply to low power drive with a half or less frequency of the commercial power supply by a frequency converter in the absence of liquid feed demand. CONSTITUTION:In the absence of liquid feed demand, switches 26, 28 are closed to start an inverter 24 while a switch 30 is opened when the phase of commercial power supply is synchronized with that of the output of the inverter 24 so that a drive power source for a motor 20 can be smoothly changed over from the commercial power supply to the inverter 24. Thus, when the output frequency of the inverter 24 is set to a half or less frequency of the commercial power supply, power required for the motor 20 through the drive of the inverter 24 can be theoretically reduced to 1/8 or less. Thus, light inverter can be selected and installation cost also reduced.

Title: Neutron detector
Inventor: MATSUMURA TOYOZO
IPC: G01T3/00
Filed: 1984-09-05
Abstract: PURPOSE:To enable selective detection of neutrons even under a relatively high dose, by converting heat energy generated from mutual action between neutrons and a substance due to nuclear reaction, scattering or the like into the electrical signal to detect. CONSTITUTION:Neutrons 1 proceeds to a detector 2 and is absorbed by nucleuses inside or outside it to impart heat energy to the detector by causing a nuclear fussion, a non-elastic scattering due to phonon or others. A part of the heat energy causes a thermal expansion in the detector to generates elastic heat waves 3. When the detector is made of pyroelectric material or piezo-electric material, the heat energy and elastic heat waves generated are converted into electrical signals 4. The proceeding of neutrons into the detector can be detected by checking the signals.
