摘要:
An image transmission apparatus transfers to an external apparatus data amount information indicating an amount of target image data and information of a priority order of the target image data. The apparatus also receives from the external apparatus a response signal indicating whether the external apparatus will accept transmission of the target image data in accordance with the data amount information, the information of priority order, and a free storage capacity to store the target image data in the external apparatus. Transmission of the target image data is controlled in accordance with the response signal.

摘要:
Anti-reflection film includes a transparent support, at least one optical functional layer overlaid on the support, and a low refractive index layer, overlaid on the optical functional layer, and having a lower refractive index than the optical functional layer. An anti-reflection film producing apparatus to produce this includes a coater for coating a surface of the optical functional layer with liquid for forming the low refractive index layer, to form a coating layer. A dryer promotes drying of the coating layer. A heater hardens the coating layer from the dryer at a first temperature level, and then hardens the coating layer at a second temperature level higher than the first temperature level, to form the low refractive index layer. Preferably, a difference between the first and second temperature levels is 1-50 deg. C. Also, ultraviolet rays are applied to the low refractive index layer after the hardening of the heater.

Whether a header information processor quickly enters a program inactive state at the timing when it issues an operation start command of an encoding process for a predetermined processing unit to a variable-length code encoder, or the header information processor enters the program inactive state upon completion of execution steps to be processed is adaptively selected in accordance with the number of execution steps. One memory is shared by the header information processor and variable-length code encoder, and address input permission means for controlling to grant permission of an address input to the memory to one of the header information processor and the variable-length code encoder is provided. The memory is used as a work area of the header information processor, and as a storage area of a variable-length code table which is looked up by the variable-length code encoder.

摘要:
To predice impending system failures, dummy messages are periodically transmitted from a surveillance computer via a message broker to a host computer that executes processes in response to electronic messages from terminals and returns an electronic message. The dummy electronic messages are time-stamped when transmitted from the surveillance computer, when received and transmitted by the message broker, and when a process is executed by the host. The surveillance computer predicts impending failures by comparing the time required while a transmitted dummy electronic message returns to the surveillance computer, a mean value of the required time, a time required while the dummy electronic message passes through the message broker, a mean value of the time for the passage, a time required for a dummy electronic message transmission between each computer and a mean value of the time for transmission to each base value.
