Abstract: A combination switch for performing various functions comprises a fixed substrate having an output contact assembly which has a common output contact and other output contacts which are electrically insulated from the common output contact. The switch also comprises a movable substrate having a switch contact assembly which has a common contact and other contacts which are electrically connected to the common contact. A switch lever is for moving the movable substrate with respect to the fixed substrate to shift the switch contact assembly relative to the output contact assembly, thereby selectively connecting the common output contact to the output contacts through the switch contact assembly to supply from the output contact assembly a pattern signal indicative of one of different conductive patterns. A processor judges, in response to the pattern signal, to which function the conductive pattern corresponds and producing an operational signal for performing the indicated function.

Abstract: In a lever switch, a contact actuating part provided in a lever is movable in a first direction by shifting of the lever and the top portion of a movable contact is depressable in a second direction substantially at right angles to the first direction while being pressed by a pressing force caused by the movement of the contact actuating part. The lever switch includes a plate which is provided between the contact actuating part and the top portion of the movable contact to convey the pressing force to the movable contact. The top portion has a sloped face facing the contact actuating part so as to form an angle of friction .theta. 1 with respect to the first direction, the plate has a central part and a side part which is bent toward the contact actuating part so as to form an angle of friction .theta. 2 with respect to the first direction, and the angle of friction .theta. 2 is smaller than the angle of friction .theta. 1.

This pear tree bears large size fruit having excellent quality, such as being highly sweet and weakly acidic.

Abstract: Disclosed herein is a Japanese pear tree having a moderate vigor and an easily maintained moderate spur development, a high resistance to black spot disease and a high productivity. This tree produces an oblate-shaped fruit which matures early in the season, i.e., from the start to the middle of August, in the central part of the Kanto district, Japan.

Abstract: Disclosed is a Japanese pear tree bearing fruit with light green yellow skin, having a strong vigor, a stout shoot and a long internode, a high resistance to scab, and a high productivity. This tree produces a circular-ellipse-shaped fruit which matures early in the season, i.e., from the middle to the end of August, in the central part of the Kanto district, Japan. The fruit has a medium size and the same weight as "Chikusui", i.e., 250 to 300 g, and a yellowish white flesh which is soft, crisp and very juicy with a high Brix, the pH of the juicy being about 4.7-4.8, and little aromatic flavor, thus having an excellent dessert quality.

Abstract: Disclosed is a Japanese pear tree bearing fruit with yellow-reddish-brown skin; having good vigor, a stout shoot, high resistance to black spot disease, and high productivity. This tree produces circular-shaped fruit which mature late in the season (i.e., from the middle to end of October), in the central part of the Kanto district of Japan. This fruit is large, with an average weight of 607 g. The white flesh is soft, crisp, and very juicy. This flesh has a moderate Brix (the pH of the juice being about 4.32) and no aromatic flavor: thus, it possesses excellent dessert quality.
