There is provided an RF tag reader and writer including: a communication unit configured to exchange signals with RF tags by performing a predetermined process unit a plurality of times; a buzzer configured to perform notification by audio output; a read-tag number determination unit configured to determine the number of RF tags which are read by the communication unit every time the predetermined process unit is executed; and a notification control unit configured to change a buzzer sounding frequency corresponding to each predetermined process unit every time each predetermined process unit is completed, in accordance with the number of the read RF tags, which is determined by the read-tag number determination unit for each predetermined process unit.
摘要:
In a process for producing a cleaning blade, a blade formed of a urethane resin is impregnated with an isocyanate compound at its surface portion. Thereafter, warm air or hot air is blown on the blade surface to remove the isocyanate compound remaining thereon, and then the urethane resin that forms the blade is allowed to react with the isocyanate compound with which the blade stands impregnated, to form a cured layer.

Disclosed is an unsaturated polyester resin composition comprising an unsaturated polyester (A) and a polymerizable unsaturated monomer (B), wherein the “shrinkage stress upon cooling” of a cured article thereof is 17 MPa or less and the ratio of the “shrinkage stress upon cooling/elastic limit” is 1 or less. The cured article has excellent gloss retention and yellowing resistance.

A method for manufacturing a centrifugal casting die includes the steps of supplying a first liquid agent for forming a backup layer to be releasably bonded to an inner surface of a cylindrical die, rotating the die body so that the first liquid agent is uniformly spread over the entirety of the inner surface of the die body, and curing the first liquid agent spread over the entirety of the inner surface of the die body to form the backup layer. A second liquid agent is applied to be bonded to be integral with an inner surface of the backup layer to form a top layer. Then the die body is rotated so that the second liquid agent is uniformly spread over the entirety of the inner surface of the backup layer and cured to form the top layer. The top layer releasably holds a centrifugally casting material supplied to the inner surface thereof.
摘要:
An electronic coupon system adds identification information for specifying users to electronic coupons every time electronic coupons are distributed among users, and when the electronic coupons are used, the identification information added to the electronic coupons are acquired as a distribution history of the electronic coupons distributed among the users. A contribution level of each user is calculated by using the acquired distribution history.
摘要:
A stall prediction apparatus of an axial compressor provided with: a rotor provided with a plurality of rotor blades; and a cylindrical casing facing the rotor blades and provided so as to cover the outer circumference of the rotor, comprising: pressure sensors provided in equal numbers at a plurality of locations in a circumferential direction of an inner wall surface of the casing, an index calculator for calculating an index (stall risk index) for evaluating the stall risk based on time-series data detected by each of the pressure sensors, and a signal processor for predicting the stall occurrence based on the stall risk indexes obtained corresponding to said each of the pressure sensors. In accordance with the present invention, it is possible to obtain a stall risk index which is highly accurate (supersensitive) and stable necessary for the active stall control, and to realize an engine control system with high reliability.

摘要:
An autonomous traveling unit is advanced toward a wall such that a charging unit is located on the right side. When a distance to the wall reaches a predetermined value not smaller than a thickness of a first member of the charging unit, the autonomous traveling unit is stopped. In this state, the autonomous traveling unit is rotated by 90° to the right so as to face a plane formed by a second member of the charging unit at the right angle. Then, the autonomous traveling unit is advanced toward the second member of the charging unit, and when a distance to the plane reaches a predetermined value, the autonomous traveling unit is stopped. In this state, the autonomous traveling unit is rotated by 90° to the right such that charging terminals face power supply terminals provided on the first member of the charging unit at the right angle. Finally, the autonomous traveling unit is run backward slightly, and when the charging terminals come into contact with the power supply terminals, the autonomous traveling unit is stopped and charging to the autonomous traveling unit is started.
