摘要:
A thin film multilayer wiring board-producing method of the present invention is intended to decrease thermal stresses developing during the formation of the multilayer construction, and also to greatly reduce the number of the steps of the process, as compared with a conventional method. A film material can be used as an insulating film of the multilayer wiring board, and is adhesively bonded to a predetermined portion. Wiring conductors are formed by electroplating. The wiring layers are repeated laminated to form the multilayer construction. A metallic film serving as an electrode is formed on one of upper and lower surfaces of a substrate, the metallic film being removed after a multilayer wiring is formed. A soluble insulating film is formed on a metallic undercoat film on the substrate, and grooves are formed in the soluble insulating film, and wiring conductors are formed in the grooves, using either electroplating or both electroplating and electroless plating. Thereafter, the soluble insulating film and the metallic undercoat film are removed. Subsequently, an insoluble insulating film is formed at those locations from which the soluble insulating film and the metallic undercoat have been removed.

A metal laminate gasket of the invention is basically formed of first and second metal plates, and a sealing device situated around the cylinder bores. The first plate includes first holes corresponding to the cylinder bores, an intermediate area located between the first holes, and two openings situated at the intermediate area. The second plate is situated above the first plate, and includes a second hole for locating therein the first holes and the sealing device. The second plate includes projecting areas with edges located on the intermediate area. When the first and second plates are assembled, the edges of the second plate pass through the openings of the first plate and are located at a side opposite to a side that the second plate is disposed. Thus, the edges of the second plate are fixed to or engaged with the first plate.

Interference detection and reduction is disclosed in which an interference carrier is reduced by processing a signal of an input frequency to a demodulator such as a PSK signal appended with bit sequence for carrier recovery and bit timing recovery for use in the TDMA system, for example, a signal of the intermediate frequency (IF) band of a 140 MHz center frequency, so that the attenuation of a band-elimination filter is limited to a value smaller than a certain one, or for the frequency bands in which spectra are produced by the bit sequence, the IF signal is combined with the band-elimination filter output via a narrow band-pass filter to control the attenuation in each of these frequency bands to a value smaller than a certain one, thereby preventing the signal quality of the TDMA signal from being degraded by the insertion of the band-elimination filter. An interference detector of a multiplexer sweep system can be obtained by combining the functions of the phase-lock loop and the filter multiplexer so as to permit the estimation of the frequency of an interference carrier with a relatively simple structure.

In a satellite communication system including a plural small earth stations (3-8), a relay earth station (2) and a satellite (1), information transmission is undertaken by primary modulation of carrier wave, and transmission of operation status of each small earth station (3-8) is carried out by secondary modulation of said carrier wave. Primary modulation may be BPSK or multiphase PSK (MPSK), and secondary modulation may be PSK, ASK or FSK. Said operation status may be receive signal quality in each small earth station, and the relay earth station (2) may adjust transmit power to said small earth station such that the receive signal quality at small earth stations satisfies desired criteria irrespective of rain attenuation.

DNA strand having an ability in biotechnological production of .alpha.-acetolactate decarboxylase is disclosed. The DNA strand is characterized in that it has a nucleotide sequence coding for a polypeptide whose amino acid sequence is substantially from A to B of FIG. 1 and which has .alpha.-acetolactate decarboxcylase activity. Also disclosed is a yeast which belongs a Saccharomyces cerevisiae and which has been transformed by the DNA strand. The yeast is characterized by the fact that its .alpha.-acetolactate producing ability is reduced, and will thus produce an alcoholic liquor such as beer which contains no or little diacetyls which have come from their precursor, namely .alpha.-acetolactate.

A mold arranged between a pair of heater blocks for molding an optical element comprises a pair of first and second elements each having a molding surface for defining a cavity and an outer surface opposite to the molding surface and in contact with a corresponding heater block, and a ring member for guiding the first and second elements. The rear surface of at least one of the first and second elements has a part which is not in contact with the corresponding heater block. Also, another mold comprises a pair of first and second elements each having a molding surface for defining a cavity and an outer surface opposite to the molding surface, a first ring member for guiding the first and second elements, and a second outer ring member made of a material with a lower thermal conductivity than that of the first ring member. A molding method for optical elements is such that a glass with a viscosity of 10.sup.12 poise or more is fed to a mold with a temperature at or below the glass transition point, heated to a temperature corresponding to the glass viscosity of 10.sup.8 to 10.sup.10 poise and pressed for 3 to 90 seconds. The glass is then cooled at a rate of 1.5.degree. to 2.5.degree. C./sec to a viscosity of 10.sup.10 to 10.sup.11 poise and thereafter at a rate of 0.2.degree. to 1.5.degree. C./sec with the glass pressurized, and removed as an optical element at or below the glass transition point.

摘要:
A deflection yoke for a cathode ray tube comprises a generally tubular core, a first deflection coil assembly including a pair of first deflection coils wound on the core and arranged in symmetrical relationship with each other about the longitudinal axis of the core and operable to deflect electron beams, traveling from an electron gun assembly towards a phosphor-coated screen region, in a horizontal direction, and a second deflection coil assembly generally toroidally wound on the core and operable to deflect the electron beams in a vertical direction. A pair of magnetic members are mounted on the core in opposition to each other and positioned on the imaginary horizontal axis perpendicular to the longitudinal axis of the core while spaced 180.degree. from each other about the longitudinal axis of the core. Each of the magnetic members is constituted by a generally elongated body having a pair of legs protruding from the elongated body which legs are spaced from each other in a vertical direction. A magnetizing member for each magnetic member is also provided for developing predetermined poles in the legs of each of the magnetic members.
