Provided are a method for producing a glass suitable for an information recording medium required to have high qualities, a process for the production of a glass substrate blank from the above glass and a process for the production of a glass substrate from the above blank. The method is for the production of a glass containing an alkali metal element by melting a glass material in a glass melting apparatus and uses, as said melting apparatus, a melting apparatus whose glass-contact portion is made of a material containing zirconium and containing substantially no alkali metal element. In the process for the production of a glass substrate blank, the glass obtained by the above method is press-molded or is subjected to a float process, and in the process for the production of a glass substrate, the above glass substrate blank is lapped and polished.

A radar system includes an arithmetic processing unit, which calculates the second derivative of the intensity of a reflected wave and determines whether a target is an upper structure or a vehicle, based on the second derivative. Alternatively, the arithmetic processing unit decomposes the waveform of the intensity of the reflected wave into frequency components and determines whether the target is an upper structure or a vehicle, based on the intensity of a predetermined frequency component.

To enable a regenerated sound in the high-note range to sufficiently reach an ear of an operator (rider) during travel. A meter display unit is provided for displaying drive information such as a vehicle speed or a travel distance. Left and right speakers are disposed on both sides of the meter display unit for generating regenerated sounds such as English conversation and music. The left speaker includes a left midrange/woofer unit disposed on the left side of the meter display unit for regenerating midrange/low-note sound and a left tweeter unit disposed between the meter display unit and the left midrange/woofer unit for regenerating high-note sounds. The right speaker includes a right midrange/woofer unit disposed on the right side of the meter display unit for regenerating midrange/low-note sound and a right tweeter unit disposed between the meter display unit and the right midrange/woofer unit for regenerating high-note sounds.

Various targets are detected in a more accurate manner. Provision is made for a receiving antenna part that has a plurality of receiving antennas arranged in a horizontal direction with a part thereof being shifted in a vertical direction from the others, and has a plurality of combinations of the receiving antennas, of which each combination detects an azimuth in the horizontal direction and an azimuth in the vertical direction of a target; and detection means that detects the target a plurality of times while changing the combination of the receiving antennas. The detection accuracy of the target can be enhanced by making a comparison between at least two detection results obtained by the detection means.

An object detecting device and an object detecting method capable of performing appropriate object detection that distinguishes an approaching moving object from a stationary object accurately. The relative velocity of an object, which exists in the lateral direction of a vehicle, with respect to the vehicle is detected, the absolute velocity of the object in the horizontal direction of the vehicle is calculated on the basis of the detection signal, and it is determined whether or not the object is an approaching moving object on the basis of the absolute velocity of the object in the horizontal direction of the vehicle. Accordingly, since it is possible to accurately distinguish whether an object existing in the lateral or oblique direction of the vehicle is an approaching moving object or a stationary object, it is possible to appropriately determine whether or not the object is an approaching moving object.

It is intended to provide a serum which contains a large amount of growth factors capable of efficiently promoting the growth of stem cells. A human serum for cell culture which shows a residual ratio of platelets remaining within 20 minutes after blood collection in relation to the whole amount of the platelets is 0% to 20%, and a release ratio of cell growth factors is 20% to 100%.
摘要:
Novel gadolinium complex compounds responsive to ions and compounds other than zinc ion, as well as MRI probes made of the compounds are disclosed. Since the gadolinium complex compounds of the present invention such as that represented by the following structural formula exhibit responsiveness to potassium ion, calcium ion, glucose or the like, by using the gadolinium complex compounds of the present invention as a MRI probe, the ion or compound in a living body can be detected and concentration distribution thereof may be determined.
