Title: Fault point detection system
Inventor: SAKUYAMA ISAO
IPC: H04B17/40
Filed: 1978-02-15
Abstract: PURPOSE:To obtain a fault-point detection system which can secure high reliability by allowing a signal transmission system which requires remote feeding to use two feeding systems, constant-current feeding for a main signal system and constant- voltage feeding for a fault search pilot signal system. CONSTITUTION:To the return line of the communication transmission section composed of transmission line K, repeater REPs 1 and 1', and REPs 2 and 2' are connected by adding one fault-point detection circuit. The fault-point detection circuit consists of oversaturation reactor T, voltage-dividing resistances Ra and Ra', rectifier circuit Di, supervisory relay RL, and adjusting resistance Rb. In case of normal feeding, a current flows to windings N1 and N1, of reactor T to decrease the impedance at the N2 sides, relay RL does not operate and contact (rl) is broken, with the section broken, no current flows to reactor T right before the disconnected section to increase the impedance at the N2 side, relay RL operates because of the constant-voltage feeding of the pilot signal system, and contact (rl) makes. Here, a fault point can be decided by detecting the pilot signal frequency.

Title: Soil improvement method
Inventor: WATANABE NORIO
IPC: E02D3/12
Filed: 1994-01-17
Abstract: PURPOSE:To obtain a uniformly improved soil with relatively low strength. CONSTITUTION:A stirring device 20 is driven to excavate the ground with a bit 22 thereof and, at the same time, ground soil is stirred with a stirring wing 23. Suspension of a stabilizer mixed with foaming agent or thickener is supplied to a foaming device 15 and, at the same time, compressed air is supplied from a compressor 10. The suspension of the stabilizer passes through the foaming device 15 to form bubble-like sterbilizer, and it is discharged from a discharge-port of the foaming device 15 into the ground. The peripheries of bubbles are surrounded by numerous fine grains of the stabilizer, so that the bubbles are not easily separated from the stabilizer even if the generated bubble-like stabilizer is in the ground, the ground can be effectively stirred by the bearing effect equipped with the bubbles, and the stabilizer is uniformly distributed in the ground. As a result, improvement soil has stabilized strength.

Filed: 1984-02-03
Abstract: PURPOSE:To enable attachment of an oil duct inside a coil without extending an average length of winding coils by arranging the oil duct to be attached inside the coil on the same plane as a riser lead wire. CONSTITUTION:Because winding coil is arranged on the same plane as a riser lead wire, thickness A of an oil duct is not added to a coil average length l2 and the equation l2=l0+(1+1/2)X2A=l0+3A is satisfied. The coil average length shortends only by 2A and the necessary quantity of winding is reduced. The area of oil-flowing-part of oil duct decrease only by the widths riser lead wires 1 and 2, but the reduced area can be offset by oil ducts 9a and 9b which are arranged on the same plane as a winding-end lead wire 3 and the cooling effect of coil can be maintained. By convection of the coil, overheat is restrained and also reliability of connection is improved.
