摘要:
The object of the present invention is to provide a base oil for hydraulic oil suitably used for hydraulic systems having filters of which micropore diameter is 50 μm or less, which is capable to improve the decrease of flow in a hydraulic pump at low temperature like −30° C. or less and capable to normally operate the hydraulic systems. The invention also provides a hydraulic oil composition using the above base oil, especially a hydraulic oil composition suitably used for such as tractors, transmissions, and common systems thereof having the hydraulic systems. In order to achieve the object, provided is a base oil for hydraulic oil comprising mineral oil, wherein the mineral oil is defined by kinematic viscosity at 100° C.: 1.5˜6 mm2/s, pour-point: −10° C. or less, viscosity index: 100 or more, % CP: 70 or more, % CA: 2 or less, and aniline point: 106° C. or more; and wherein, the mineral base oil is treated by catalytic dewaxing process and/or contains tertiary carbon atoms at a ratio of 7.4% or more to the total carbon atoms.

摘要:
A wireless blood glucose meter is a battery-powered apparatus to communicating wirelessly with a portable terminal, and includes a blood glucose level detector that measures a blood glucose level, a transmitter that transmits the blood glucose level measured by the blood glucose level detector to the portable terminal, a receiver that receives a response signal sent from the portable terminal in response to the transmission of the blood glucose level by the transmitter to the portable terminal, and a voltage monitor that monitors the output voltage of the battery. A transmission control circuit changes the transmission method used by the transmitter on the basis of the output voltage of the battery as detected by the voltage monitor.

In a color correction method of performing correction by dividing the color plane into a plurality of areas, and correcting the color according to different methods for each divided area, color shifts generated in converting color signal vectors are prevented from arising.When determining which area of the color signal plane divided by area boundary lines passing through the origin of the color signal plane includes the input color signal vector, and correcting the input color signal vector by converting the input color signal vector using a correction matrix having been designated in advance for the area determined to include the input color signal vector, a correction matrix including a component for performing parallel translation and a component for performing linear transformation is used as a correction matrix.
摘要:
A wireless blood glucose meter (2) has a blood glucose level detector (21), a transmitter (22), a receiver (23), a storage component (24), and a transmission power determiner (25). Whether or not an acknowledge signal has been received and the transmission power when the transmitter (22) has transmitted a blood glucose level are stored as history information in the storage component (24), and the transmission power determiner (25) determines the transmission power when the transmitter (22) transmits on the basis of the history information stored in the storage component (24).

摘要:
It is an object to provide an information recording medium with which information symbols can be suitably read. This information recording medium comprises a sheet-form member (33), a plurality of information symbols (18) that are displayed on the surface of the sheet-form member (33) and each have the same information, and an edge line (34) that is provided at one end and/or the other end of the sheet-form member (33) and allows an information reading device which reads the information symbols (18) to recognize the end of the sheet-form member (33).
摘要:
Provided is a handset comprising a transceiver transmitting and receiving data to and from a base, a data error detector determining whether or not there is an error in the data received by the transceiver, and a reception duration controller changing a specific reception duration. If the data error detector determines that there is an error, then the reception duration controller extends a reception duration of the transceiver so as to receive the data newly sent from the base and to reduce unnecessary calling repetitions between the base and the handset and reduce wasted waiting time.
