Abstract:
The changing of the azimuth of directivity in which the azimuth of directivity of the antenna that achieves the maximum gain thereof is switched to the azimuths of tires is performed repeatedly for a plurality of cycles during a transmission duration of information. The output value of the antenna whose azimuth of directivity is controlled is sampled separately for each of the azimuths of directivity subjected to the switching. The sampled values are sorted into groups separately for each azimuth of directivity, and are accumulated separately for each group. The position of the tire shown by the azimuth of directivity of the group whose accumulated value is the largest is determined as being the position of the tire equipped with the transmitter that is transmitting the information.
Abstract:
A pressure buffer is disposed in an ink supply path that connects an ink supply source to an ink-jet head to suppress pressure fluctuations due to vibrations created by movement of a carriage. The pressure buffer includes a chamber having an ink flow inlet through which ink flows from the ink supply source into the chamber and an ink flow outlet through which the ink flows from the chamber to the ink-jet head. A partition wall disposed within the chamber extends at least partly along a side wall of the chamber to define an ink flow path that communicates at its upper end with the chamber and at its lower end with the ink flow outlet. A through-opening is provided in the partition wall in the vicinity of the ink flow outlet and through which the ink flows between the ink flow path and the chamber to suppress pressure fluctuations in the ink flow path. Alternatively, an air pocket may be provided in the partition wall in the vicinity of the ink flow outlet to reduce presure fluctuations in the ink flow path.

An electronic apparatus is provided. A management hoard includes: a control section; a real-time clock that outputs data indicating current date and time to the control section; a memory that stores fiscal data including the data indicating the current date and time and fiscal information under the control of the control section; and a power source that supplies power to the real-time clock through a power supply path. A housing box includes a box main body and a cover. The housing box that houses the management board. When the cover is in a closed state, the power supply path is formed and the power is supplied to the real-time clock. When the cover is placed in an open state, the power supply path is shut off and the power supplied to the real-time clock is shut off.
Abstract:
An input image signal is coded by an encoder to be outputted as a basic code string, and the basic code string is delayed by a code-string delay circuit for a predetermined period of time to be outputted as an additional code string. The basic code string is synthesized with the additional code string by a code-string synthesizer to be outputted as an output code string. Thus, there is provided an image data coding system which can quickly restore data even if the data is lost due to error and in which the increased code amount is less than the cycle refresh and the error correction.

Abstract:
A laser output power command determination value from a controller (17) is input to an upper limit current determination unit (32), and an upper limit current value to be decided based on the laser output power command determination value is determined. Then, a second comparator (30) compares a command current value determined from the laser output power command determination value and a laser output power command determination value measured with a power monitor (13), with an upper limit current value determined with a upper limit current determination unit (32). The second comparator (30) determines a command current value when the upper limit current value is greater than the command current value and the upper limit current value when the command current value is greater than the upper limit current value, as a reference current value, by which reference current value a current to be supplied to pumping means is configured to be controlled. In such a configuration, an upper limit current value is determined according to a laser output power command determination value, whereby an increased current to be supplied to the pumping means, i.e., the increase of energy to be supplied to a laser oscillator apparatus is avoided, and an energy loss in the optical component is reduced, which prevents damage development from leading to the replacement of the component.
Abstract:
A laser generator includes a generation means for pumping by a pumping light source (7) a pumping medium (3) to generate a fundamental-wave laser beam, an output sensor (6) for measuring average output power or pulse energy of the fundamental-wave laser beam, a wavelength-conversion element (5), arranged on an optical path for the fundamental-wave laser beam, for converting the fundamental-wave laser beam into its higher-harmonic-wave laser beam, and a controller (9) for memorizing a determination value set to a value lower than a breakage threshold for average output power or pulse energy of the laser beam converted by the wavelength-conversion element (5), and for, when the measurement value becomes not lower than the determination value, controlling the output power of the fundamental-wave laser beam to be a value lower than the breakage threshold; thereby, the beam intensity through the wavelength-conversion element (5) never exceeds the breakage threshold, and thus breakage of the wavelength-conversion element (5) can be prevented.
