Abstract: A semiconductor memory device includes a plurality of semiconductor pillar projections separated by grooves formed in longitudinal and transverse directions in a substrate and arranged in a matrix manner, a MOS capacitor and a MOSFET formed on side surfaces at lower and upper portions, respectively, of each pillar projection, a diffusion layer of a source or drain of each MOSFET formed in an upper end face of the pillar projection, and a bit line connected to the diffusion layer. The bit line is in contact with the upper end face of the pillar projection in a self-alignment manner.

Abstract: The novel compounds are provided with good antibacterial and antitumour activity.

Abstract: A multi spark ignition system using an ignition capacitor and an ignition transformer uses a device for providing charging energy to the ignition capacitor. A field effect discharge switching means is used for discharging the energy that is stored in the ignition capacitor through the primary winding of an ignition transformer. An oscillator is used for causing the discharging switching circuit to operate intermittently with a proper cycle. An additional controlling circuit controls the consumption of additional magnetic energy which is stored in the ignition transformer when it is in its non-operative state. Two returning means are used to consume the magnetic energy or for returning the energy and the ignition transformer under the non-operative and operative states of the discharge switching circuit.

Abstract: A method of manufacturing an air-tight ceramic container is disclosed. This method includes the steps of coating an active metal consisting of Ti and/or Zr on an opening end face of a ceramic tubular member in an amount of 0.1 to 10 mg/cm.sup.2, thereby forming an active metal layer, placing a brazing filler metal on the active metal layer, placing a metal cover member for shielding an opening portion of the ceramic tubular member so that a peripheral portion end face of the metal cover member is in contact with the brazing filler metal, and melting the brazing filler metal by heating, thereby brazing the metal cover member to the opening end face of the ceramic tubular member.

Abstract: A carrier medium for a coloring matter, which comprises an ink absorbent and a substance present on the surface of the absorbent, which has an adsorptivity of from 20 to 100 mg/g.

Abstract: Thienothiophene dyes of the formula ##STR1## wherein Z is carboxylate, acyl, carboxyl, substituted or unsubstituted carbamoyl, cyano or nitro, X is hydrogen, fluorine, chlorine, bromine, Z or a group of the formula ##STR2## T.sup.1 and T.sup.2 are identical or different and each is independently of the other cyano, substituted or unsubstituted alkoxycarbonyl, alkenyloxycarbonyl, carbamoyl or alkylcarbamoyl and W is hydrogen, methyl or ethyl, Y is hydrogen, chlorine or bromine and K is the radical of a coupling component, are highly suitable for dyeing synthetic fibers, in particular polyesters wherein the dyeing obtained have good fastness properties.

Abstract: A method of producing retort food comprises the steps of enclosing and sealing in a packaging container meat such as animal meat or fish meat broiled with a flavoring liquid containing a soy component in such a manner that the content of amino nitrogen originating from said soy component within the flavoring liquid is 0.08 to 0.25% by weight and also containing 4.8 to 8.0% by weight of salt, and subjecting the meat to retort sterilization processing at a temperature of 115.degree. to 130.degree. C. under a gauge pressure of 0.8 to 1.7 kg/cm.sup.2 for 5 to 60 minutes.This method is applicable to the production of retort foods from various soy-broiled meats and is capable of eliminating browning and generation of any unpleasant taste.
