Title: Transmitting device for radar signal
Inventor: MOCHII MASAMI
IPC: G01S7/00
Filed: 1982-02-26
Abstract: PURPOSE:To perform a transmission of radar signal through a small number of optical fiber cables, by a method wherein a number of radar signals are digitally time-divided for multiplexing, and they are converted into light to transit them through the optical fiber cables. CONSTITUTION:A signal from a device 6 at a transmitting side at a transmission section of a radar system is time-divided for multiplexing through an interface circuit 7 by a multiplexer 8, and is converted from an electric signal to a light signal by an electro-optical converting circuit 9 and brought to a multiple light wavelength to send it as an output light signal 9a at a transmitting side through an optical fiber cable 10. An input light signal 10a entering a reception side in which a light wavelength thereof is separated and a light signal thereof is converted into an electric signal by a photo-electric converting circuit 11, enters a time-division separating circuit 12, where it is separated into various original signals being sent to a device 14 at an reception side of a radar by an interference circuit 13.

Title: Distance detector
Inventor: NAGAOKA AKIRA
IPC: G01C3/06
Filed: 1984-02-20
Abstract: PURPOSE:To reduce errors of measured values as much as possible even when regularly reflected light enters a photodetection lens by correcting the distance of a body which is detected by a position detecting element with the output of a photodetecting element which is arranged on an optical path and detects the distribution state of the quantity of light. CONSTITUTION:A position detecting element 5 on which reflected light from the glossy surface of a body 3 to be detected is formed through the photodetection lens 4 sends outputs 11 and 12 corresponding to the center of gravity of the formed image to a distance correcting circuit 6. Outputs of photodetecting elements 7 and 8 are processed by subtracting and adding circuits 9 and 10 and inputted to a correcting circuit to detect the distribution state of the quantity of light, and a regularly reflected light display circuit 13 is driven to display it on a pilot lamp 14. When the glossy surface of the body 3 slants, the reflected light contains a regularly reflected light component and the center of gravity of the formed image shifts, so it is corrected by the correcting circuit 6 to reduce errors of measured values. Therefore, the body 3 to be detected has the glossy surface and varies in angle, accurate measured values having a small error are detected.

Title: Reset circuit for cyclic digital filter
Inventor: NURIYA KOZO
IPC: H03H17/04
Filed: 1985-02-20
Abstract: PURPOSE:To prevent malfunction of the title circuit by detecting an overflow caused due to application of power by a comparator and keeping the filter in a reset or set state. CONSTITUTION:A quantized signal is inputted to an input terminal A of an adder 13 via an input register 11 and an output of a register 12 is inputted to an input terminal B. A comparator 14 compares a sign bit of the input terminals A, B with a sign bit of the output of the adder 13. The comparator 14 compares two sign bits added to the adder 13 as the maens for detecting the overflow with a sign bit of the output of the adder 13, the condition of overflow is taken as 'the polarity of two input sign bits is identical and only the sign bit of the output of the adder different', a reset signal is generated as the result of comparison to reset the register 11 and the register 12. Thus, when any overflow takes place, the width of the shift is halved.

Title: Polling control system
Inventor: OKADA TATSUO
IPC: H04L12/403
Filed: 1983-02-28
Abstract: PURPOSE:To design a communication controller with good processing efficiency by delaying the transmission of a polling sequence according to the number of consumer station equipments in polling operation and controlling the equipment to prevent the overload. CONSTITUTION:A coomand sent from a central processor is written in a section C in an area 141 corresponding to a corresponding communication circuit number in a channel correspondence memory 13. If the command indicates polling at this time, a microprogram checks a counter 21, and when its value is 0, a delay inhibition bit E in an area of the channel correspondence memory 13 corresponding to a communication circuit is set to ''1'' to advance the contents of the counter 21. Every time the polling command is sent out, the counter increases in its contents and then decreases the contents by one when the polling sequence transmission is completed. Thus, the number of other circuits in polling operation is grasped and a delay time corresponding to the number of circuits is found by using a delay time table 18 provided in a control memory 16 and set in a delay circuit 27 to adjust the transmission time of the polling sequence, preventing overload.

Filed: 1980-03-15
Abstract: PURPOSE:To enhance the corrosion and weather resistances of a steel sheet coated with Si-contg. Al by hot dipping by heat treating the sheet to spheroidize Si particles in the hot dipped Al layer. CONSTITUTION:A steel sheet coated with Al by hot dipping with a bath usually contg. 4-11% Si is heat treated at 500-570 deg.C. As a result, the form of eutectic part Si particles is converted from the needlelike form into coarse spheroidal form to reduce the surface area of the Si particles and increase the distance between the particles, whereby the corrosion of the hot dipped layer is made hard to occur and proceed. By the heat treatment the weather and corrosion resistances of the sheet are enhanced considerably.
