Title: Signal injecting method for power line carrier
Inventor: FUKAO ISAO
IPC: H04B3/56
Filed: 1991-05-14
Abstract: PURPOSE:To efficiently realize power line carrier at low cost by injecting a signal voltage to a secondary coil side by using a current transformer for gauge. CONSTITUTION:When the signal voltage is injected to the secondary coil side of current transformers 21 and 22 for gauge as general electric equipments, on a primary coil side, a voltage corresponding to the current transformers 21 and 22 is generated. When inserting signals between three-phase power distribution lines by using these current transformers 21 and 22, the current transformers 21 and 22 are inserted into two phases (R and S phases) and when the signal voltage is injected while connecting the secondary coil side to a reverse polarity, the signals can be injected to the primary side of the R and S phases. As a result, the double signals can be injected between the lines of the R and S phases. When injecting signals to three-phase power distribution lines as a zero phase voltage, the current transformers are inserted into all the three phases and when the signal voltages are injected while parallelly connecting the secondary side coil, the signals can be injected to the respective primary sides or R, S and T phases. Then, this voltage snows signal injection as the zero phase voltage.

Filed: 1985-07-23
Abstract: PURPOSE:To prevent clogging by smoothing connection, in the connection part of an auxiliary pipe connecting a spray hose and an air hose and a main pipe connecting a concrete hose to the auxiliary pipe, by forming either one of both pipes into a flat shape. CONSTITUTION:When a concrete pump 1 and an air pump 7 are started, concrete is sent under pressure through a concrete hose and air is supplied through an air hose 8 and concrete passes through a main pipe 10 at the place of a connection apparatus 4 to be sent to the flat part of an auxiliary pipe 9. At this time, because the diameter D of the main pipe 10 does not vary and the area of the flat part 11 is smaller than that of the main pipe 10, clogging is apt to generate at the flat part 11 but, because air is supplied to a spray hose 5 from the air hose 8 in a larger pressure feed amount, concrete is sent to a nozzle gun without generating clogging.

Title: Optical by-pass repeating network
Inventor: NAKAMURA MASARU
IPC: H04B10/27
Filed: 1982-09-20
Abstract: PURPOSE:To execute effectively a by-pass without forming in multiplex an optical line for the by-pass, by distributing an output of an optical transmitter of a pre-stage repeater into two by an optical distributor, so that one of them is received by the first optical receiver and the other is supplied to the second optical receiver of the following stage repeater. CONSTITUTION:Each repeater 11 receives separately an optical signal from an optical transmitter 12 of the repeater 11 of the pre-stage by operating the first optical receiver when the repeater 11 of the pre-stage is normal, and receives an optical signal by-pass-outputted through an optical distributor 13 of the repeater 11 of the pre-stage by operating the second optical receiver 15 in case when abnormality occurs in the repeater 11 of the pre-stage. The optical signal received selectively by the first or the second optical receiver 14, 15 is amplified, shaped, etc., and is outputted from the optical transmitter 12, by which the optical signal is relayed. In this way, overlapping of signals does not occur, also there is no possibility that the same signal goes round, and it is unnecessary to provide doubly an optical line for a by-pass.

Abstract: PURPOSE:To securely identify a defective area by recording a deleted data mark signal having a certain pattern at an inversion interval larger than Tmax in a recording defective area and controlling a deleted data mark detecting means in accordance with an average reflected light beam at recording. CONSTITUTION:Read checking is executed by a read circuit 16. When a recording defect is detected, a microcomputer 19 switches the modulated and recorded waveform of a semiconductor laser 1 into the deleted data mark signal in the recording defective area to write again. Afterwards, when a data reading request in the defective area is issued, a comparator circuit 21 compares the reproduction signal of a photodetector 15 with a comparison voltage (c) set by a D/A converter 20 to output a signal (d). A deleted data mark detecting circuit 22 detects the defective area and outputs it to the microcomputer 19, which discriminates the defective area, invalidates read data and accesses an alternative area.
