Title: Phase-synchronizing circuit
Inventor: ISHIRO YOSHIMITSU
IPC: H03L7/10
Filed: 1980-03-31
Abstract: PURPOSE:To improve C/N ratio by a simple circuit and to eliminate the delay of pull-in time by inputting to a frequency contrl oscillator the DC component of the voltage that corresponds to the phase difference between both output signals from a reference signal generator and a frequency converter and by compensating a rough tuning frequency by comparing the integral value of the said voltage with upper and lower limit values of frequencies which can be phase-synchronized. CONSTITUTION:The output of frequency control oscillator 1 is frequency-divided by frequency converter 5, whose output is compared with the output signal of reference signal generator 4 by frequency phase comparator 3; and loop filter 2 extracts the DC component of the voltage signal that corresponds to the phase difference from the reference signal and then applies the component to frequency control oscillator 1 to control the oscillation frequency. On the other hand, the said reference signal and the frequency-division output are inputted to the 2nd frequency phase comparator 17 and the integral value of the voltage that corresponds to the phase difference is inputted from integrator 7 to frequency-synchronizing circuit 8, which compares is with preset upper and lower limit values and, when it is greater or less than the upper or lower limit value, compensates the rough tuning frequency of frequency control oscillator 1.

Abstract: PURPOSE:To protect a semiconductor laser from noise and surge without deteriorating the accuracy of an optical system in a high heat conductivity state at the time of assembly by providing a radiator connected to an enclosure cover by means of a coupling made of a flexible material having heat conductivity. CONSTITUTION:The heat of a semiconductor laser 6 is transferred to an enclosure cover 8 through a radiator 11 and coupling 12 and discharged to the output from the cover 8. Therefore, when the cover 8 is air-cooled from the outside, a sufficient cooling effect can be obtained. In addition, in order to couple the cover 8 which has no sufficient dimensional accuracy due to the heat radiation with the laser 6 which is used as the light source constituting an optical system requiring strict dimensional accuracy, the coupling 12 must have flexibility. Moreover, in order to make the light source 6 to be brought into contact with a main body 3 or cover 8 so as to prevent surge destruction by continuity, the radiator 11 must have an insulating property. Therefore, an insulating material is used for the radiator 11 so that the laser 6 can be sufficiently insulated from the cover 8. Namely, the laser 6 is maintained in a sealed state and prevented from being damaged by noise, because the laser 6 is sealed with the metals of the cover 8 and main body 3.

Title: Multiple stuff conversion device
Inventor: KOZARU YASUTAKA
IPC: H04J3/07
Filed: 1990-02-22
Abstract: PURPOSE:To execute stable communication by detecting the change of a stuff rate caused by the frequency fluctuation of a lower group signal according to the result of comparison between a write clock signal and a read clock signal on the side of a transmitter, and controlling the output frequency of a higher group oscillator when this stuff rate is different from a reference value set in advance. CONSTITUTION:When a phase comparator 14 executes the phase comparison between a write clock signal WC and a read clock signal RC of a buffer memory 11 and the phase difference between the both signals is less than the specified phase difference set in advance as the result, a stuff request signal ST is inputted not only to a multiplexing circuit 12 but also to a stuff rate detecting circuit 15. Based on the signal ST, the stuff rate detecting circuit 15 detects the stuff rate and compares the reference stuff rate set in advance with the detected stuff rate and when the both rates are different, a control signal CS is generated to control the output frequency of a higher group oscillator 13. According to this control signal CS, the higher group oscillator 13 generates a clock signal CK, which frequency is controlled, and supplies it to the multiplexing circuit 12. Therefore, the stuff rate is always controlled constant.

Abstract: PROBLEM TO BE SOLVED: To prevent marine pollution by drawing out a bag-like fluidal matter receivoir opening upward from a landing pier to the underside of a part position where a fluidal matter can flow out, at cargo handling of a marine vessel. SOLUTION: When cargo handling of a fluidal matter is executed in a marine vessel A, a fluidal matter receivoir 1 is drawn out of a landing pier 21 up to the underside of a part position where the fluidal matter can flow out such as the connecting part 3 of a cargo handling pipe 31, so as to receive the fluidal matter flowing out of the connecting part 32. In this case, by pulling a rope 11 with a winch 33, the fluidal matter receivoir 1 is advanced along a guide rail 22, and drawn out from the underside of the pier 21. Next, by pulling a rope 10, the receivoir 1 is retreated along the rail 22, and received on the underside of the pier 21. When the bag 4 of the receivoir 1 is drawn up over the sea surface, a rope 9 is pulled up so as to fold the bag 4 upward. When the fluidal matter is lighter than the sea water, the bag 4 can be formed into a cylindrical shape. Hereby, marine pollution can be effectively prevented, and the collected fluidal matter can be utilized as a product.
