Abstract: A device management apparatus is adapted to be connected to devices which constitute at least one device group. An application is running in the device management apparatus. Each of the device managers is associated with one of the devices and is operable to create usage information of the associated one of the devices. A device group manager is associated with the at least one device group and coupled to the device managers to receive the usage information from each of the device managers. The device group manager is operable to notify the usage information in response to an inquiry from the application.

Abstract: A POS terminal apparatus is adapted to be connected to an external device. With an application running in the POS terminal apparatus, a device manager determines whether the external device is capable of counting a first value indicating a usage amount of the external device, and if so, the device manager acquires the first value from the external device in response to a first command from the application. A counter retains a second value indicating the usage amount of the external device and notifies the second value to the application in response to a second command from the application. If it is determined that the external device is not capable of counting the first value, the counter virtually counts the second value in accordance with a third command sent from the application to the external device. An updater updates the second value with a third value which is obtained by a fourth command from the application. The first value is retained even when the second value is updated with the third value.

Abstract: An unsaturated polyester resin composition containing 8 to 20% by weight of unsaturated polyester resin, 4 to 12% by weight of liquid thermoplastic resin, 8 to 20% by weight of glass fiber, and 50 to 75% by weight of inorganic filler, the unsaturated polyester resin containing 5.10 to 5.90 mmol/g of double bond group concentration, 1.50 to 2.50 mmol/g of ether linkage group concentration, 1.05 to 1.30 mmol/g of isopropylidene linkage group concentration, 2.50 to 3.50 mmol/g of ethylene linkage group concentration, and 3.20 to 3.60 mmol/g of methylene linkage group concentration per 1 g of unsaturated polyester.
