Filed: 1994-09-12
Abstract: PURPOSE: To carry out an optimum air-conditioning by providing two dampers for covering two air outlets in a chamber having three air outlets formed at equal intervals on a lower surface and rotating the dampers respectively by a prescribed angle so as to close the opened air outlets. CONSTITUTION: Two dampers 4 cover the two air outlets 3 of three air outlets 3 to close the air outlets 3. One end of each damper 4 is fixed to the rotating shaft 5 passing through both side plates of a chamber 1. This rotating shaft 5 is rotated by 180 deg. so that the damper 4 is rotated by 180 deg. to close the adjacent air outlet 3. Accordingly, the position of the air outlet 3 serving as the outlet of conditioned air can be changed. For example, if load in a room is increased and the amount of supply of conditioned air is insufficient, when the closing damper is opened, the amount of supply of the conditioned air can be increased.

Title: Ultrasonic fluid transferring pump
Inventor: TODA KOJI
IPC: H02N2/00
Filed: 1991-08-28
Abstract: PURPOSE:To accurately control a minute flow rate in a ultrasonic fluid transferring pump whose driving source is an ultrasonic actuator. CONSTITUTION:When an alternate signal which has the same resonance frequency as that of a piezoelectric transducer 1 is applied thereto, a unidirectional vibration displacement is generated on one side of the piezoelectric transducer 1 in a direction of a polarization axis. The vibration displacement is transmitted to a rotational body 2 through a frictional member 3. The rotational body 2 rotates, and a bearing 4 provided thereon also rotates. When the bearing 4 rotates while pressurizing an elastic tube 5 onto a guide 6, the elastic tube 5 suctions fluid with its recovery force. The fluid inside the elastic tube 5 is transferred in a moving direction of the bearing 4. A minute flow rate is thus accurately controlled by pulsative driving. Since this construction does not require a magnet, it can be used under a strong magnetic field. Since this contstruction does not require a gear, it can be reduced in its size and weight, generating no noise. In addition, enables the capability of reverse rotational driving enables the directional change of flowing fluid. The capability of self- exciting driving enables electric reduction of electric consumption performance.

Filed: 1989-09-20
Abstract: PURPOSE:To enable transferring without wrinkling a colored place and its peripheral part by pressing the transferable transparent colored layer of a transfer tape against a predetermined marking place to transfer the transferable transparent colored layer to the marking place. CONSTITUTION:A transfer tape 1 is constituted when a colored ink layer 1c is placed on one surface of a filmy base material 1b made of resin film or paper and a pressure-sensitive sizing material layer 1d, which is solid at normal temperature and transparent or translucent to the extent of being able to recognize matters written at the marking place, is placed on the colored ink layer 1c. When the filmy base material 1b side of the transfer tape 1 drawn out from a transfer tape wound body R by the biasing head 5 of a marker means is pressed against the marking place 4, the colored ink layer 1c and pressure- sensitive sizing material layer 1d are integrally pressure-sensitive transferred as a transferable transparent colored layer 1a to the marking place 4 to color said marking place 4. Therefore, the thin transferable transparent colored layer can be transferred in a state, where wrinkling is hard to occur, without applying a large tensile force to the transfer tape.
