An image editing system having an excellent editing operational efficiency. A recording/reproducing unit where compressed images have been recorded and an editing terminal unit are interconnected through a communication line. The compressed image which is needed at the time of editing is transmitted via the communication line without having recourse to a physical recording medium.
摘要:
A process for the efficient production of a D-amino acid from the corresponding DL-5-substituted hydantoin by one-step reaction which comprises using a composite immobilized enzyme at a pH about neutrality, said composite immobilized enzyme being obtained by immobilizing a hydantoinase having its optimal pH within an alkaline range and a D-N-carbamyl-.alpha.-amino acid amidohydrolase having its optimal pH about neutrality in a coexisting state on an immobilizing support, simultaneously, is disclosed.

In a process for the production of a D-.alpha.-amino acid, in which an N-carbamyl-D-.alpha.-amino acid corresponding to the general formula: ##STR1## wherein R represents phenyl, hydroxy-substituted phenyl, substituted or unsubstituted alkyl, or thienyl, is converted by a microbial enzyme in an aqueous medium to a D-.alpha.-amino acid corresponding to the general formula: ##STR2## wherein R is the same as defined above, decarbamylase produced by a microorganism of the genus Comamonas, Blastobacter, Alcaligenes, Sporosarcina, Rhizobium, Bradyrhizobium or Arthrobacter is used as the enzyme converting the N-carbamyl-D-.alpha.-amino acid to the D-.alpha.-amino acid.The conversion of the N-carbamyl-D-.alpha.-amino acids to the D-.alpha.-amino acids is carried out in a neutral to alkaline pH range.

A handheld blower has a body including a combustion engine and a blower section driven by the combustion engine, and a handle coupled to the body. The blower section has an air outlet directed forward with respect to an operator. The handle has a grip portion extending in a front-back direction with respect to the operator, a front arm extending from a front portion of the grip portion to the body, and a rear arm extending from a rear portion of the grip portion to the body. The front arm and the rear arm are more flexible in the front-back direction than in directions perpendicular to the front-back direction.

To provide a work machine in which traveling devices and an implement device can be operated by common operating levers, wherein switching operation is easy and a changeover is easily confirmed. Inside a cab of the work machine, there are provided travel pedals, with which the traveling devices can be operated, and operating levers, with which the traveling devices and the implement device can be operated. A changeover switch is provided on a console positioned in the vicinity of one side of an operating sheet. The changeover switch switches over between a traveling mode, in which traveling operation is possible by the operating levers, and a work mode, in which implement operation is possible by the operating levers. The work machine has a controller which makes it possible to work by the operating levers when the travel pedal is not stepped on in the case where the work mode or traveling mode is selected by the changeover switch, and makes it possible to travel by the operating levers only when the travel pedal is stepped on in the case where the traveling mode is selected by the changeover switch.

摘要:
A DNA fragment coding for a decarbamylase protein improved in thermostability as the result of replacement of at least one base of a DNA fragment coding for a decarbamylase protein derived from a microorganism with another base and the resultant replacement of at least one of the corresponding amino acids, and its production process; a vector containing the DNA fragment; a transformant obtained by transformation with the vector; as well as a decarbamylase improved in thermostability and its production process. Also disclosed is a process for producing a D-.alpha.-amino acid, which comprises converting an N-carbamoyl-D-.alpha.-amino acid into the corresponding D-.alpha.-amino acid in an aqueous medium by the action of a decarbamylase having a thermostable temperature of 65.degree. C. or higher; and collecting the D-.alpha.-amino acid produced.
