Abstract: A recorder wherein moisture condensation in the windway due to temperature difference between the windway itself and the breathing passing therethrough is prevented, so that the sound will not be blocked by the moisture adhering to the windway during performance.A heating means is attached to a tube member of the windway unit to reduce the temperature differences between the windway and the breathing blown into the windway to minimum to thereby prevent moisture condensation. When there is no moisture condensation in the windway, there will be no turbulence in the breath blown through the windway, assuring adequate amount of breathing to be supplied from the outlet to correctly act on the edge of a sounding window.

Abstract: A wrist watch with an alarm having a vibratory plate supported at a point inside the bottom housing of the wrist watch. The vibratory plate comprises a piezoelectric element, a base electrode fixed on one side of the element. Audible time sound is emitted through the bottom housing, which produces transmitted vibrations by the application of AC voltage to the piezoelectric element.

Abstract: A novel synthetic resin made wind instrument having high rigidity in spite of its thin-walled body portion and capable of producing sympathetic sounds with excellent timbre is provided according to this invention. The wind instrument provided according to the first embodiment of this invention comprises an inner pipe with a small wall thickness, an outer pipe also small in wall thickness, and a plurality of ribs provided in the hollow portion formed between said inner and outer pipes. The outer pipe is press-fitted over the inner pipe so that said both pipes are securely joined to each other. According to the second embodiment of this invention, there is provided a wind instrument composed of an inner pipe, an outer pipe and a plurality of ribs formed therebetween, wherein a rigidity reinforcement layer formed by metal plating or other means is provided in the surface areas defined by the external surface of the inner pipe and the side faces of the ribs.

Abstract: Complex enzymes which can lyse the cell wall of a variety of microorganisms such as bacteria, fungi, yeast, Basidiomycetes and chlorella are produced and recovered from cultivation of Pellicularia sasakii or Pellicularia filamentosa.

Abstract: A pulse motor comprising a rotor having at least two magnetization axes extending parallel to a shaft of the rotor and angularly spaced apart at a uniform interval, the direction of magnetization of each magnetization axis being opposite to that of the adjacent magnetization axis; a pair of upper stators extending above the rotor and defining two upper gaps between them, said upper gaps being adapted to face respective unlike polarity poles on the upper side of the rotor; a pair of lower stators extending below the rotor and defining two lower gaps between them, said lower gaps being adapted to face respective unlike polarity poles on the lower side of the rotor; and at least one drive coil for magnetizing the upper and lower pair stators alternately to opposite polarities such that the polarity of one of the upper pair stators and one of the lower pair stators is opposite to the polarity of the other upper and lower stators.
