Title: Optical input disconnecting/detecting circuit
Inventor: YAKO HIROSHI
IPC: H04B10/07
Filed: 1989-02-06
Abstract: PURPOSE:To obtain a circuit immune from the effect of oscillation of a timing extracting system circuit, and capable of detecting the input disconnection of an optical signal at a constant detecting level by comparing the output of a peak detecting part with a prescribed threshold. CONSTITUTION:A comparing part 4 detects the input disconnection of the optical signal by comparing the output of a peak detecting part 3 with the prescribed threshold. The peak detecting part 3 and the comparing part 4 constitute an optical disconnection detecting circuit. Even when an optical signal input level decreases to some extend, a gain is increased so as to hold an output amplitude to a constant level by an automatic gain control part in an equalizing amplifying part 2. The gain of the equalizing amplifying part 2 has a ceiling value, when the optical signal input level extremely decreases such as the case of the optical input signal disconnection, the output level of the equalizing amplifying part 2 cannot be held to the constant value, and it decreases. Consequently when the optical signal input level extremely decreases such as the case of optical input signal disconnection, the decrease of the output level of the equalizing amplifying part 2 is detected by the peak detecting part 3, and by comparing the output of the peak detecting part 3 at such a time with the prescribed threshold by the comparing part 4, the input disconnection of the optical signal can be detected.

IPC: F28F9/16
Filed: 1980-03-04
Abstract: PURPOSE: To maintain the airtightness at the connecting parts of the heat exchanging tubes of a heat exchanger by a method wherein a thermosetting resin is poured into a molde where heat exchanger tubes have been fixed, and then heated to harden the resin to constitute a tube plate.  
     CONSTITUTION: The end part of each heat exchanger tube 1 is degreased, and a concave part 4a of a mold 4 is sprayed with a releasing agent. Then, the end part of each heat exchanger tube 1 is fitted with a projection 4b of the mold 4 so as to be blanked off and fixed. Then, a thermosetting resin 3a is poured into the concave part 4a. After the resin 3a has hardened on heating for a given period of time, the mold 4 is removed. Thereby, the working of the tube plate and the heat exchanger tubes can be omitted, and the airtightness at the connecting parts can be maintained owing to the thermal expansion coefficient difference between the heat exchanger tubes and the tube plate.

Abstract: PURPOSE:To attain positioning in a short period without developing deviation in terms of positioning even if steady external force is applied and the permit the application of the positioning method to an object to be controlled with quick response by providing an error deciding means and a manipulated variable calculation means. CONSTITUTION:The error deciding means 7 decide whether or not the position deviation (X0-X) calculated by a subtractor 1 lies within an expected error range F. If not, the means 7 outputs zero, and selects a set of an integration gain I1, a position gain P1 and a speed gain D1 out of two set of gains preset to the manipulated variable calculation means 12. If the deviation 4 lies within the range F, the set of gains I2, P2 and D2 is selected. The means 12 obtains the product of the integration gain I1 and a deviation integration value 6, that of the position gain P1 and the deviation 4 and that of the speed gain D1 and a speed measurement value V13, and the sum of the products is outputted as a manipulated variable. Thus the positioning deviation will not occur under the steady external force, and positioning can be made in a short time, and can be applied to the control target with quick response.
