An antimicrobial agent utilizes a resin having acrylonitrile and styrene and/or a conjugated diene as units. The antimicrobial agent includes a metal-salt-containing copolymer, and the metal-salt-containing copolymer is obtained by treating a copolymer containing acrylonitrile and at least one of styrene and a conjugated diene as units with an acid to thereby introduce acid radicals into the copolymer, and converting at least part of the acid radicals into a salt of at least one metal selected from among Ag, Cu, and Zn.

In a flow control device performing a credit-based control, in order to eliminate a deadlock state with an opposed device due to a discard of data or a credit, a flow management table of a transmitting side flow control device stores a number of data transmitted to an opposed device and a number of credits received from the opposed device, and a management portion transmits a request for correction information to the opposed device and corrects the data transmission number and the credit reception number based on the correction information received. Alternatively, a management portion of a receiving side flow control device notifies the correction information (e.g. difference between data transmission number and data reception number, and credit transmission number) for the data transmission number and the credit reception number of the opposed device in response to the correction information request from the opposed device.

An appliance includes a housing-case, a main unit of such appliance and an optional structural member, wherein at least portions of the housing-case and the structural member are made of biodegradable material containing polylactic acid as a major component is provided. Such appliance can achieve durability sufficient for the practical use without causing environmental impact if the housing-case and structural member thereof are disposed as they are.

There is disclosed an optical information record medium having an optical information record layer on a transparent substrate, in which the transparent substrate is made of a resin material mainly consisting of a polycarbonate resin that contains no more than 4 wt % of low molecular weight fractions having a weight average measured with respect to a polystyrene molecular weight of no more than 3500, in order to avoid a double refraction of an optical information record medium resulting in an improved signal to noise ratio and having superior thermal-transformation resistance and impact resistance.

An X-ray generating apparatus provided with at least one deflecting means disposed between a freely selected pair of adjacent deflecting electromagnets and adapted to undulate electrons around a design orbit. When the deflecting means if formed of variable horizontally or vertically deflecting electromagnets capable of forming a variable magnetic field for electron on the orbit, the electrons are undulated around the design orbit and synchrotron radiation or powerful wiggler radiation from a wiggler is generated to irradiate a large area of a given substrate. Thus, in the transfer of patterns for the production of LSI devices for example, the X-ray generating apparatus enables highly intensive X-rays abundantly containing soft X-rays to be emitted uniformly to irradiate a wide area.

The packet transmission device including: a first and a second storage module to store a token value; a token controller to add a predetermined token value to a first total token value, and subtract a predetermined token value from the first total value in response to the output of the packet; an overrun state controller to add an excess of the first total token value over a predetermined upper limit value to a second total token value, in the case where the first total token value added by addition control is greater than or equal to the predetermined upper limit value; and an underrun state controller to subtract a predetermined token value from the second total token value and add the subtracted token value to the first total token value, in the case where the subtracted first total token value is less than the predetermined upper limit value.

The present invention provides a polyester resin component having crystallization improved and including a cyclic compound shown by a below-described formula and polyester capable of having a crystal structure. (In the formula, a ring A and a ring B respectively represent benzene rings, and hydrogen bonded to the benzene rings may optionally be substituted with other groups. Y represents —CONH— or —NHCO—. X represents a heterocyclic group or a condensed heterocyclic group including one or more NH or CO respectively).
