摘要:
An antenna system having a main reflector, a sub-reflector, and a plurality of horns for radiating different frequencies includes a beam waveguide system which cancels cross polarization otherwise inherent in the system. If the antenna system uses a non-rotationally-symmetric sub-reflector the cross polarization caused thereby is cancelled by the beam waveguide system having at least two focusing reflectors and selected parameters. Alternatively the beam waveguide system can be used with a rotationally symmetric and stationary sub-reflector by being positioned to reflect said beam on the axis of the main reflector. Either the horns or the focusing reflectors may be rotatably switched, the other group being stationary.

A detection device is retained in the rumen of a cow by being orally administered to the cow, and detects the state of the inside of the rumen. The detection device wirelessly transmits measured values of the rumen pH as detection results. A monitoring unit (receiver and monitoring server) acquires information transmitted from the detection device, and monitors the state of the inside of the rumen. The detection device is configured to be recoverable orally from the rumen of the cow. The operating conditions of the detection device are recorded in the detection device ahead of time, and can be updated by means of a wireless signal transmitted from a setting unit to the detection device.
摘要:
The present invention provides a method for selecting a marker for diagnosis of the nutritional status capable of reflecting the status of a particular nutrient in a plant without being influenced by various stresses in environmental factors, etc., and a method for diagnosing the status of a particular nutrient in a plant using a marker for diagnosis of the nutritional status selected by the method. A metabolite quantitatively changed depending on only the amount of a particular nutrient in a plant is selected as a marker for diagnosis of the nutritional status reflecting the status of the nutrient in the plant.

摘要:
A card insertion slot in the card connector through which two types of cards, large and small cards, can be selectively installed in a card accommodation space include first and second guideways in corresponding to the sizes of the cards. The card connector includes first and second contacts, a lock bracket configured to detect the width of the large card, an actuator configured to be rotatable, and a partition member including a partition plate configured to be movable. When the large card is inserted into the card connector, the lock bracket is moved from the first position to the second position. When the large card is further fed into the card connector, the actuator is rotated from the first position to the second position, and the partition plate is moved from the first position to the second position.
