Title: Washing timing detecting device in pipe
Inventor: SAHODA NORIYUKI
IPC: F16L55/00
Filed: 1989-06-26
Abstract: PURPOSE:To detect an underwater suspended matter flowing in a pipe before they reach a recognizable state via naked eyes by projecting light from a light emitting device to a light receiving device via the suspended matter while the underwater suspended matter is accumulated on a holding section from a dust collector guide section, and outputting a signal from a control device when the light received quantity reaches the signal value. CONSTITUTION:When a suspended iron compound enters a dust collector 2, the dust collector 2 has a larger diameter than that of a water service pipe and a larger volume, thus the flow speed of the city water is made slow, and the flow speed of a suspended matter is made slow. The suspended matter is guided by a guide section 4 and finally held by a holding section 5. The light from a light emitting device 7 is shielded by the held iron compound or the like, and the voltage fed to a control device 9 from a light receiving device 8 is decreased. When the voltage fed to the control device 9 from the light receiving device 8 is decreased to the preset voltage value or below, the control device 9 judges it, a cleaning timing command in a pipe is outputted to a transmitting device 10 from the control device 9, and the command is reported to a monitoring center from the transmitting device 10 via a telephone line 11.

Filed: 1989-06-26
Abstract: PURPOSE:To attain efficient confirming test of communication after installation work and connection of accurate communication by receiving a specific signal and a polarity identification signal returned from a line termination section through a telephone line and identifying the line termination section and its polarity. CONSTITUTION:When a signal transmission/reception section 7 connects to a terminal (equipment 15 via a terminal identification equipment 13, the transmission/reception section 7 confirms it that the terminal equipment 15 is in no communication state and sends a prescribed start signal.

The equipment 13 supplies the start signal to a discrimination circuit 19 via a signal induction section 17 and when the circuit 19 detects the signal, a power supply section 25 is started to activate a terminal specific signal transmission section 21. When the transmission section 21 is operated, the signal specific to the terminal equipment 15 is sent. When the transmission/reception section 7 receives the specific signal, the said signal is analyzed to identify the signal to be a signal from the termination section of the line 11, and the result of identification is outputted from a display recording section 9 and displayed.

Title: Time division multiplex circuit
Inventor: ARITOU YOSHIYUKI
IPC: H04J3/04
Filed: 1991-06-05
Abstract: PURPOSE:To facilitate the attachment/detachment of a memory, to prevent an electrostatic break down from occurring by securing a constitution where a write control circuit controls a switching part with reception of a write command and inputs the write data and an address to an EEPROM to perform a writing operation and therefore reducing the packing area of the memory storing the control data. CONSTITUTION:When the control data stored in an EEPROM 2 is changed, a write command signal is given to a control signal generating circuit 3 from the outside of a unit. The circuit 3 sends a control signal to the EEPROM 2 to set a write mode. At the same time, the circuit 3 sends a control signal to a multiplexer 4 for selection of the write address signal received from a connector 7 and also to a bidirectional buffer 5 for selection of the write data given from a connector 7. In such a constitution, the EEPROM 2 writes the write data in sequence into the positions of addresses given from outside. Then the write command signal is turned off and the circuit 3 is set in a read mode. Thus the data are read out of the EEPROM 2 by a read address signal and under the control of the circuit 3.

Filed: 1987-06-26
Abstract: PURPOSE:To heighten heat transfer coefficient, by determining the pitches of heat transfer tubes in the direction at right angles with an air flow larger than those in the flowing direction of air, by providing raisings on the surface of a fin, and by disposing the heat transfer tubes so that the projected area of the first row tubes do not overlap on the third and the fourth row tubes, although the first ones partially overlap on the secondary row tubes. CONSTITUTION:The projected area 15a of heat transfer tubes 10a in the first row to the downstream side against the flowing direction of an air 14 is partially overlapped on the heat transfer tubes 10b in the second row, positioned directly after the first row tubes so that bridged or louver type raisings 13 can be provided getting into the after-flow part of heat transfer tubes. As a result sufficient rate of air can be passed through the raisings, and the front edge effect of boundary layers by the raisings can be fully utilized. In case that condensate adheres on the surface of a fin, it can easily drop passing between the first and the second rows of heat transfer tubes, so that the heat exchanging rate does not lower. By those effects, a compact and highly efficient heat exchanger with fin can be realized.
