Patent EP-0270727-A2 (EP)
Inventor: MIYAKE KATSUNOBU
IPC: F16K27/02
Filed: 1987-02-13
Abstract: This invention is intended to solve such problem that a valve casing for use in a butterfly valve formed by press working is advantageous in the aspects of productivity, thickness and weight, but has a serious disadvantage of breakage or deformation lowering in sealing performance due to getting out or ageing of the seal ring when the valve is mounted on pipe line and clamped from both sides. From this point of view, a valve casing according to this invention is formed into a double structure composed of an inner shell and an outer shell, the inner shell comprising a cylindrical part defining a bore and seal ring receiving portions formed on both ends with their diameters enlarged larger than the cylindrical part, substantially forming a S-shape in section the outer shell defining a space by surrounding a whole outer periphery of the inner shell, and the inner shell and the outer shell being superposed each other at both end of the valve casing.

Abstract: A two way radio system employing power control of a remote station transmitter to produce a predetermined received signal level at a fixed site after handoff of the remote station from one radio channel to another is disclosed. A signal strength measurement is made on the in-use channel and a power level for the remote station transmitter is calculated from the measured signal strength, a predetermined nominal signal strength desired on the target radio channel, and a linear correlation of signal strength and remote station power level steps. The calculated remote station power level is then transmitted to the remote station as part of a handoff command.

Abstract: To reduce the sensitivity of a sensor element (30) providing a frequency-modulated signal without intervening in the actual sensor (32), it is proposed to ''thin out'' the output pulses of the sensor element (30) by means of constant-frequency pulses. In a sensor unit which in each case provides one or several measurement pulses after receiving a start pulse, this is achieved by the fact that a part of the pulse period is predetermined by a timing stage (44) which operates in dependence on a constant-frequency auxiliary oscillator (46). The output signal of the timing stage turns on a gate circuit (36) which is inserted between the sensor element (30) and a subsequent frequency divider (38 to 42) which provides the measurement pulse.

IPC: B22D11/06

Abstract: A method and system are provided for synchronizing the travelling edge dams (30) in the continuous casting of metal slab, strip or bar, thereby providing a means for the continuous uniform casting of longitudinally spaced edge shapes, contours, or profiles such as integral shoulders, lugs, lobes, depressions, curves, or indentations in the opposite edges of the cast product. Shapes include the protruding lugs, cast directly opposite each other, for suspending copper anodes in electrolytic refining--also the intruding, material-saving contours in the tops of anodes. A belt-type continuous casting machine is shown wherein two moving contoured edge dam loops each comprise blocks (32) strung upon flexible endless metal straps (34). The moving edge dams (30) on each side of the mold must by synchronized, regardless of disturbing thermal variations notably. "Back breakers" (201) exert upward rolling contact force controllably and separately against each moving edge dam loop along its return path, thereby changing the local curvature and so adjusting the degree of mutual compression and closeness of the constituent dam blocks (32) or the end-to-end spacing of the same. Such compression effectively shortens the elevated edge dam loop and thereby hastens its revolutions. Known previous methods or heating or cooling to synchronize the edge dam loops may advantageously be used in addition to back-breaker (201) control. The positioning of separate "back'breaker" apparatus (201) in an inverted configuration near the entrance to the moving mold (M) results in a significant improvement in the sealing capability of the entering edge dams (30) against the lower casting belt (24) where molten metal is introduced.

Abstract: The radio transmitter-receiver system for increasing or decreasing communication channels comprises radio transmitter-receivers (11, 11A, 12, 12A, 13, 13A) each including a separated intermediate frequency portion for modulation and demodulation and a separated microwave portion and having a multiplexer (78) and a divider (90) therebetween. Local oscillators (75) in the intermediate frequency portion have a variable frequency function and the operating frequency of the intermediate frequency portion can be easily changed. The intermediate frequency portions are connected to the microwave portions through the multiplexer (78) or the divider (90) and the frequency of the microwave to be communicated is easily changed. Thus, an increase or decrease of the communication channels is possible at a low cost.

Abstract: A process for preparing a substrate, e.g., an epoxy printed circuit board, for subsequent metallization. Active chemical sites are formed adhering to the substrate surface. The substrate is then exposed to a vapor of a volatile organometallic compound, which chemically reacts with the active sites and is decomposed to at least a species of the metal constituent of the compound. This species adheres to the substrate and can be transformed into the free metal which is useful as a seed for subsequent electro­less deposition of a metal thereon. If selective deposition is desired, a resist masking layer is used prior to forming the seed layer.

The bottom surface and side surfaces (115a, 115b, 117a, 117b) of the block are also covered with bottom and side conductive layers electrically connected to the inner conductive layers at the bottom surface. The inner conductive layer is further connected to spaced apart top conductive layer portions (131a, .... 131d) provided on the top surface of the block surrounding each hole. The top layer portions are spaced from each other and have an oblique edge portion which is capacitively coupled with, and obliquely faces an upper edge portion of the side conductive layers, the oblique edge facilitating adjustment of the resonant frequency by removal of a predetermined amount of conductive material therefrom. In accordance with the method of manufacture of this filter, the filter is initially con­structed to have a resonant frequency which is greater than that ultimately desired, and after measuring the resonant frequency initially obtained, a predetermined amount of conductive material is removed from the top conductive layer   at a location along the oblique edge portion according to the required reduction in resonant frequency in order to reduce the resonant frequency to a desired value.
