Title: Adaptive filter control circuit
Inventor: FUJII KENSAKU
IPC: H04B3/23
Filed: 1989-11-29
Abstract: PURPOSE:To use a large coefficient correction coefficient even in the case of using the arithmetic processing for a definite arithmetic word length to attain coefficient estimate calculation stably by stopping the correction of a filter coefficient when the ratio of power integration value and an instantaneous square value is lower than a prescribed value. CONSTITUTION:A power integration value calculation means 1 calculates a power integration value of a data signal and an instantaneous square value calculation means 2 calculates the instantaneous square value of the data signal. A ratio arithmetic means 3 calculates the ratio of the power integration value and the instantaneous square value and a comparison means 4 generates a control signal stopping the correction of a filter coefficient when the ratio is lower than a prescribed value. Thus, even in the case of the arithmetic processing for a definite arithmetic word length, a comparatively large coefficient correction coefficient is used to execute the coefficient estimate calculation stably.

IPC: H01F41/02
Filed: 1990-11-16
Abstract: PURPOSE:To prevent final shape precision from deteriorating by forming an air hole communicating with the outside at a specific part of the cavity formation surface of a die so as to allow the air to escape actively from the corner sections where molding pressure within the cavity becomes extremely high and make the molding density of ferrite uniform. CONSTITUTION:In the upper surface of the lower die 1, there is a square concave portion 2 that conforms to the product shape and the upper die 3 is designed to be fit perfectly into the concave portion 2. Next, in order ro actively remove air fro the four corners of the cavity where the molding pressure is particularly high, the air holes 5 which communicate with the outside are formed at the lower four corners of the upper die 3. Then, a specified amount of ferrite powder is added into the concave section 2 of the lower die 1, the upper die 3 is placed into the lower die 1 and pressure is applied. At that point, the air in the cavity is smoothly released from the four corners through the air holes 5. As a result, changes in the contraction rate in certain spots during sintering and deterioration of the final product shape can be prevented.

Filed: 1990-11-16
Abstract: PURPOSE:To improve a heat transfer rate within a pipe at a condenser by a method wherein the condenser is formed by one pipe having the same circumferential length at a pipe sectional surface and a refrigerant passage cross sectional area is decreased in a step-wise manner from an inlet port toward an outlet port. CONSTITUTION:A cycle in a refrigerator is comprised of a compressor 1, a condenser 2, an expansion device 3 and an evaporator 4 or the like. Each of the aforesaid devices 1 to 4 within a easing 5 is connected by a pipe so as to cause refrigerant to be circulated. The pipe is contacted with refrigerator walls 6a and 6b at their surfaces and its circumference is covered by a thermal insulating material 7. In particular, in a condenser 2 formed of one pipe having the same circumferential length at its cross section, a cross sectional area of passage in a heat transfer pipe is increased at its upstream side near an inlet port where there are many gas regions, its cross sectional area at the passage at a downstream side near the outlet port where a liquid region occupies a high rate is decreased and a flow speed in the liquid region is promoted. With such an arrangement, it is possible to improve a heat transfer rate in the pipe and keeping the same surface area of the pipe enables a heat transferring area to be prevented from being decreased.

Title: Signal line switching system
Inventor: TAMURA KYOKO
IPC: H04M3/00
Filed: 1986-12-26
Abstract: PURPOSE:To improve the efficiency of use of a link in which the routes of signal lines forming a signal path from a terminal office to the central station can be made shortest and least in number by making the central station identify a bit of failure information and set an alternative route, and to inform the end office of the alternative route. CONSTITUTION:The central station 10 designates a repeater station 20 against the terminal office 40 an normal operation. In case a signal line in route (a) encounters a failure, the repeater station 20 detects the failure, and transmits the failure information to the central station 10. The center 10 recognizes this failure information by means of its own received information analysis means 12 and failure identification means 14, and informs of an alternative route setting means 15 of the failure information. The setting means 15 retrieves an alternative route from an alternative route table 13 by using the failure information, and changes the repeating point from the repeater station 20 to a repeater station 30 for the alternative route, and designates it. Thus set alternative route is informed to a transmission control means 17, and the means 17 changes a route in a route table 16 to the alternative route, and at the same time, controls so that the changed rounte is transmitted to the terminal office 40 via a transmission signal forming means 18 and a signal transmission means 19. As a result, the end station 40 can be connected to the central station 10 through the shortest routes (d), (c).
