摘要:
An indicating plate for a solar watch, comprising a color diffusion plate which, by virtue of the presence of a coloring agent, a coloring light diffusing agent, a colored translucent substrate, a pattern layer/colored thin film layer and a diffusion layer, is adapted to transmit a portion of light having a wavelength within a range capable of causing a solar cell housed under the indicating plate to generate power. The color diffusion plate is adapted to make it difficult to view the solar cell from the outside through the indicating plate and is also adapted to impart a color tone to the indicating plate.

A seeding machine comprises: an air compressor for generating a positive air pressure; a soil hardness sensor for measuring soil hardness so as to produce a control signal to adjust the positive air pressure generated by the compressor; an air pressure adjuster for adjusting the positive air pressure generated by the air compressor in accordance with the control signal produced by the soil hardness sensor; a negative air pressure generator for generating a negative air pressure by making use of air under the positive air pressure; a change-over valve for effecting a change-over operation between the positive air pressure and the negative air pressure, so as to selectively supply the positive air pressure or the negative air pressure; a seed adsorber for catching a seed by virtue of the negative air pressure; a first air cylinder adapted to extend or contract by the positive air pressure, to cause a certain reciprocating movement of the seed adsorber; a second air cylinder adapted to extend or contract by the positive air pressure, to cause a reciprocating movement of the seed adsorber between a seed catching position and a seed ejecting position.

The heat-sink plates on which the rectifier diodes are mounted are fastened to an insulating base member essentially of the shape of an arc of a circle of between 240.degree. and 320.degree.. Opposite the position of each of the diodes, which each have a lead extending alongside but spaced from the insulating member, a connection device with inwardly and outwardly extending lugs is affixed to the insulating base member, the inwardly extending lug being connected to the diode lead and the outwardly extending lug being connected directly (or indirectly through a strapping wire) to a lead of the stator winding of the alternator. This construction enables diode leads to be connected before installation of the rectifier unit in the alternator casing and facilitates soldering the stator winding leads to the assembly. The connectors may be crimped sleeves or bent-up wire devices.
摘要:
A compound having the formula: ##STR1## wherein Ring A is monohydroxyphenyl, or a pharmaceutically acceptable acid addition salt thereof is prepared by catalytic hydrogenation of a compound having the formula: ##STR2## wherein A' is monobenzyloxyphenyl, and Y is carbonyl or hydroxymethylene. The compound (I) in which Ring A is 4-hydroxyphenyl or 3-hydroxyphenyl is useful as a cardiotonic agent. On the other hand, the compound (I) in which Ring A is 2-hydroxyphenyl is useful as an anti-diabetic agent.
摘要:
A compound of the formula: ##SPC1##Wherein Ring A' is dibenzyloxyphenyl and Y is carbonyl or hydroxymethylene, is subjected to catalytic hydrogenation. A compound of the formula: ##SPC2##Wherein Ring A is dihydroxyphenyl, is produced. The product is useful as a cardiotonic agent. It is also characterized by the high potency ratio of adrenergic .beta..sub.1 -receptor stimulating activity to adrenergic .beta..sub.2 -receptor stimulating activity.
