The amplifier includes a carrier amplifier circuit having an amplifying element operable in class-AB or class-B, and a plurality of peak amplifier circuits which have amplifying elements operating in class-B or class-C and which are arranged to start an operation in stages in response to an input level. An output of the carrier amplifier circuit and outputs of the peak amplifier circuits are combined together for signal output. One of the peak amplifier circuits which is rendered operative at the lowest input level is smaller in saturation output than the carrier amplifier circuit.

摘要： A vulcanizing machine for producing pneumatic tires includes an exchangeable segmented mold comprised of tread mold pieces for defining the outer contour of a tire tread portion, and upper and lower side mold members engaged with the tread mold pieces, for defining the outer contours of the sidewall portions. The tread mold pieces are detachably connected to connector segments which are slidably engaged with a container ring so that vertical movement of the container ring causes radial movement of the connector segments relative to the tread mold pieces. After production of tires of a predetermined size has been completed, the mold is removed from the machine by moving the container ring upwards to disconnect the connector segments from the tread mold pieces, and disconnecting the upper side mold member from a top plate of the machine. Another segmented mold for tires of a different size is incorporated into the machine, by placing and centering the mold relative to the machine, moving the container ring downwards to connect the connector segments to the tread mold pieces, and connecting the top plate to the upper side mold member. The mold can be efficiently exchanged with respect to the machine under a high temperature condition, thereby improving the manufacturing productivity of tires.

摘要： The present invention provides a compound a piperidine derivative having excellent histamine receptor antagonistic action, which is useful as active ingredients of a pharmaceutical composition, especially an antihistamine. The piperidine derivative of the present invention has a potent histamine receptor antagonistic action. Further, the compound of the present invention shows low brain transfer even in a cerebral receptor binding test where a mouse is orally administered with the compound, so that the compound has preferred properties of alleviating side effects in the central nervous system, such as drowsiness. The piperidine derivative of the present invention is very useful as a novel antihistamine having smaller side effects in the central nervous system, such as drowsiness.
