There are provided a thermochromic opaque composition capable of exhibiting change in transparency together with change in color in response to temperature variation, a laminate member employing the same, and a three-dimensional article capable of concealing and revealing the interior, utilizing the laminate member. The thermochromic oaque composition is formed by dispersing a thermochromic material, capable of developing and erasing color by an electron donating-accepting reaction, in small particles in vinyl chloride-vinyl acetate matrix resin. The above-mentioned structure realizes reversible change in transparency, together with change in color, in response to temperature variation, with hysteresis with a temperature difference of 10.degree. C. at minimum to 50.degree. C. between the high and low trigger temperatures.

As a charger-side connector is pushed into a car body-side connector, push-out slanting surfaces of a spring plate slide respectively along push-out slanting surfaces of a deep hole halfway, and therefore a restoring force tends to push the charger-side connector back. Namely, if the hold is released halfway, the two connectors are moved away from each other, so that the electrical connection is broken. On the other hand, when the connector is pushed until each leading portion of the spring plate passes past a peak defined by a portion of connection between a drawing slanting surface the push-out slanting surface of the deep hole, the charger-side connector is drawn. Namely, although the connector is pushed out halfway, it is drawn when it passes past this halfway point, so that the two connectors are automatically connected together electrically if the hold is released.

An engine valve feed apparatus which feeds engine valves to a valve handling apparatus at a valve pick-up station where the valve handling apparatus picks up and fits the engine valves to an engine cylinder head one after another. The apparatus comprises a valve hanger plate formed with a number of valve holes for tightly receiving a number of engine valves to hang the engine valves upside down. A hanger plate transfer unit transfers a number of the valve hanger plates to the valve pick-up station cone after another. An engine valve thrust-up unit is disposed at the valve pick-up station for thrusting up the valves from the valve hanger plate at the valve pick-up station so as to allow the valve handling apparatus to hold a stem of each of the engine valves. The engine valve thrust-up unit has a holding member movable up and down and formed with a number of positioning holes for receiving the stem ends of the engine valves hung from the valve hanger plate to thereby hold the valves upright when moved up. A stopper prevents the valve hanger plate from being forced up when the stem ends of the engine valves are pushed up from the valve hanger plate.

In order to control the clubroot of brassica vegetables which is settled-planted in a farm field, it is necessary to previously treat the seedling with a chemical before settled planting or treat the soil with a chemical, but the clubroot is sometimes not controlled depending on the weather or soil conditions. In addition, the treatment with a fungicidal compound at a high concentration causes a problem of phytotoxicity or crop persistence. An object of the present invention is to solve these problems and provide a method for easily and simply controlling clubroot without causing a problem of phytotoxicity or crop persistence. The present invention provides a method for controlling clubroot, comprising applying cyazofamid to brassica vegetables after seeding or settled planting in a farm field.

This invention provides pyrimidine derivatives represented by a formula, in the formula, ring A stands for carbocyclic group or heterocyclic group, X1 stands for hydrogen, lower alkyl, amino, etc., X2 stands for hydrogen or lower alkyl, Y stands for a direct bond or sulfur or nitrogen, n stands for an integer of 0-4, and Ar stands for a group of the following formula, or a salt thereof, which concurrently exhibit 5-HT1A agonistic activity and 5-HT3 antagonistic activity and are useful for therapy and treatments of diseases such as IBS. The invention furthermore provides a therapeutic method of IBS, characterized by having 5-HT1A agonistic activity and 5-HT3 antagonistic activity work simultaneously and cooperatively in vivo, which comprises either administering 5-HT3 antagonistic agent which concurrently exhibits 5-HT1A agonistic activity, or administering 5-HT1A agonistic agent and 5-HT3 antagonistic agent simultaneously, in sequence or at an interval.

The invention relates to a MIMO-HARQ communication system and communication method. When a receiver carries out a CRC for received data streams and detects an error in a data stream, it feeds back to a transmitter and requests a retransmission of the data stream. The transmitter determines the correspondence between the data streams to be transmitted and a plurality of transmitting antennas in a method for retransmitting the error data stream with a transmitting antenna other than the one having transmitted the error data stream. Transmission and retransmission of a same data stream experience different spatial fading channels, so that an additional spatial diversity gain is obtained by exchanging the transmission sequences, in addition to a time diversity gain obtained by retransmission, and hence the probability of successful transmission is improved.
