Title: Optical isolator
Inventor: YAMADA YUICHI
IPC: G02B27/28
Filed: 1988-09-10
Abstract: PURPOSE:To prevent a reflected return light from being fed back to a semiconductor laser by displacing a wedge-like magneto-optical element whose thickness is varied gradually in the vertical direction of an optical axis, in the vertical direction against the optical axis, and fixing it in a position where the reflected return light becomes minimum. CONSTITUTION:A wedge-like magneto-optical element 1 is placed so that a saturation magnetic field is applied into a magnet 2. A light beam which passes through a polariz er 3 becomes a linearly polarized light, its polarization direction is rotated by 45 deg. at the time of passing through the wedge-like magneto-optical element 1, and said light beam passes through an analyzer 4 which is placed at an angle of 45 deg. against the polarizer 3. On the contrary, a reflected return light passes through the analyzer 4 and becomes a linearly polarized light, and at the time of passing through the wedge- like magneto-optical element 1, its polarization direction is further rotated by 45 deg. by non-reciprocity which a Faraday effect has, and it is orthogonal to the polarizer 3, therefore, the linearly polarized light cannot pass through. In such a way, a high isolation ratio of the same degree as that of a two-stage connection type optical isolator is obtained by a constitution of the same degree as that of a one-stage optical isolator, and it can be prevented completely that the reflected return light is fed back to a semiconductor laser.

Title: Resistance-time logarithmically transforming circuit
Inventor: ISHIYAMA FUMIO
IPC: G01D5/16
Filed: 1985-10-09
Abstract: PURPOSE:To obtain a resistance-time logarithmically transforming circuit with a high transforming accuracy by constituting the circuit such that the electric charge of a charged capacitor is discharged through by a resistor and measuring the elapsed time from the initiation of a discharge to the inversion of a comparator. CONSTITUTION:In the condition that a capacitor C is charged by switching means S, the output voltage of a differential amplifier 1 is negative and a state that the whole current I1+I2+I4=0 is maintained. When I2 decays to approach to I1, the output voltage is inverted to positive at a condition I2=I1. Therefore, the time (t) from the time when the capacitor C is initiated to be discharged by turning off the means S to the time when the output of the differential amplifier 1 is inverted from negative to positive is proportional to the logarithm of a resistance (r) to be measured. At the moment of an inversion, following is true: t=CRln(E2r/E1R); and the time (t) is given as the linear function of the logarithm of the resistance (r) to be measured. Since above-described resistance-time logarithmically transforming circuit utilizes the ideal exponential function of a discharge circuit, the logarithmically transforming circuit can perform a highly accurate logarithmic inversion and, since the quantity to be inverted is time, can be digitized by a simple circuit.

Title: Heat transfer tube and manufacture thereof
Inventor: KONO KYOJI
IPC: F28F1/34
Filed: 1987-09-11
Abstract: PURPOSE:To improve the performance of a heat transfer tube, by arranging flat fins in zigzag with inclinations with respect to the axis of the tube, which are opposite to each other. CONSTITUTION:Absorbing solution 5, sprayed from the upper part of a heat transfer tube 1, flows down while meandering between flat fins 2 arranged in zigzag. The flow passage is meandered, therefore, the flow passage of the absorbing solution 5 becomes long and a period of time of the stagnation of the absorbing solution 5 between fins 2 is elongated. Further, the flow of the absorbing solution 5 is disturbed by the flow down of the absorbing solution 5 along the flat fins 2 and the cutting of the flat fins 2 finely with a predetermined interval whereby the density of the absorbing solution 5 in a diaphragm is unified and the thickness of the film of the solution is also unified. In addition, the zigzag arrangement of the fins 2 makes a temperature and speed boundary layer 8 thin by turbulent flow effect and breaks the layer 8, whereby a temperature difference between the absorbing solution 5 and the fins 2 can be maximized. According to these methods, the performance of the heat transfer tube may be improved.
