Abstract: The present invention relates to a fine spherical particle having uniform molecular orientation having uniform molecular orientation, which is useful in fine chemical fields or electronic and information fields, such as a functional material and a medical material, using membrane formation of a bicephalic compound; a spherical microcapsule encapsulating a hydrophilic core substance; and a process for producing the same. The fine spherical particle can be produced by immersing a substrate having hydrophilicity in an aqueous solution of a salt of the compound represented by the following formula (1) to precipitate the fine particle under an acidic atmosphere. wherein R represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms; n is an integer of 8 to 20; and m is an integer of 1 to 3.

Abstract: An optical information recording medium is disclosed. The optical information recording medium has a transparent substrate having pits and lands corresponding to information signals formed therein, and a reflective layer formed on the transparent substrate. The reflective layer is composed mainly of a dye material and a polymeric material and has a reflectance of 15 to 25%. The polymeric material forming the reflective layer is a silicon varnish.

Abstract: An optical recording medium wherein a recording layer capable of optically recording and reproducing the information is formed on a substrate, and wherein the information is recorded with a light beam having a wavelength shorter than that of a replay light beam. A film thickness d of the recording layer is set so as to satisfy the relation d.ltoreq.1.75.lambda./n, where .lambda. is the wavelength of the replay light beam and n is the real part of the complex index of refraction of the recording layer with respect to the replay light beam. The real part of the complex index of refraction of the recording layer with respect to the replay light beam is not less than 2.55, while the absolute value of the imaginary part of the complex index of refraction of the recording layer with respect to the recording light beam is not less than 1.0. The organic dye may be enumerated by a cyanine compound and a porphyrin compound. If the porphyrin compound is used, blue-hued laser recording becomes possible.

Abstract: In an electric apparatus which accommodates a built-in microcomputer which is supplied with power at all times regardless of a state of switching of a main power switch for an electric apparatus, a reset circuit for the microcomputer wherein a key-on monitor monitors a duration of keying of a reset key and derives a detected signal therefrom at the time when the key is depressed continuously over a predetermined threshold time, and a reset signal generator generates a reset signal based on a detected output of the key-on monitor and resets the microcomputer for initialization. According to this reset circuit, the built-in microcomputer can readily be reset without disconnecting the main power supply, that is different from the conventional apparatus wherein the reset is performed by detaching the attachment plug from the receptacle.
