Abstract: There is provided a wireless-type power supply method that is applied to the case where an object to which energy is to be transmitted is relatively small, such as a micromachine, and that allows high-voltage electrical energy to be transmitted without using a wire. In this method, the optical energy from an light source is converted into high-voltage electrical energy by means of an energy transducer formed of either a piezoelectric element or a photovoltaic element on the above-described object, and the high-voltage electrical energy is supplied to an actuator, whereby the construction of the receiving side of the energy transmission is simplified.

Abstract: An optical actuator includes pairs of stators disposed parallel to each other with a stipulated gap between them, a mover disposed moveably within the gap, and a number of photovoltaic devices. The photovoltaic device has device electrodes on either end in the direction of polarization, each connected to one of the pair of stators. The voltage generated by the photovoltaic effect of the device is utilized to generate force that displaces the mover with respect to the stators by means of electrostatic force arising from the voltage.

Abstract: There is disclosed an optically transparent pressure sensitive adhesive sheet for heat transfer image pattern formation comprising an optically transparent film which has a first side constituting a heat transfer image pattern-receiving side and a second side opposite to the first side, an antistatic release sheet provided on the second side of the optically transparent film, via a pressure sensitive adhesive layer. Also disclosed is a first embodiment of an optically transparent decorative pressure sensitive adhesive sheet comprising the optically transparent pressure sensitive adhesive sheet and an image pattern formed by heat transfer method on the first side of the optically transparent film.

Abstract: Cellulase may be prepared in good yield and at relatively low cost by culturing certain mutant strains of the genus Trichoderma, which exhibit increased inducibility of cellulase by L-sorbose, in medium wherein the carbon source comprises cellulose-containing material of plant origin, for example, bagasses, waste papers, rice plant hulls and straws or soybean wastes. Preferred mutant strains are exemplified by Trichoderma reesei PC-1-4, PC-3-7, X-30 and X-31.

Abstract: Ethanol is produced by culturing the microorganism Kluyveromyces cellobiovorus or Kloeckera apiculata in a medium containing, as a carbon source, an assimilable source of xylose, cellobiose or both. The carbon source may be provided in the form of hydrolysates of cellulose containing substances such as cotton, wood, straw or paper which are obtained by acid hydrolysis or enzymatic action. At the completion of culturing, ethanol is removed from the culture in a conventional manner.
