Abstract: An air clean apparatus including an air intake intended to be located at a lower position in a corner of a room and an air outlet intended to be located at an upper position in the corner of the room, and at least a filter and a blower both inside the air clean apparatus, characterized in that, when the air clean appratus is installed in a room, a given quantity of circulating blowing air, the given quantity is decided according to the height from the floor underneath the air intake and the underside-open area determined on the basis of particles of the maximum size to be eliminated at the air intake.

Abstract: The object is to provide an Air clean appratus that cleans up floating dusts in air in a room and is configured in a shape that can be placed in dead space in a room and will not be an obstacle when it is placed in a room. [Means for Achieving the Object] An Air clean appratus comprising an air intake 13 intended to be located at a lower position in a corner of a room and an air outlet 14 intended to be located at an upper position in the corner of the room, and at least a filter 15 and a blower 18 both inside the Air clean appratus, characterized in that, when the Air clean appratus is installed in a room, a given quantity of circulating blowing air, the said quantity is decided according to the height from the floor underneath the air intake and the underside-open area determined on the basis of particles of the maximum size to be eliminated at the air intake.

Abstract: An antiseptic clean system according to the invention is designed to effectively and thoroughly destruct not only drifting microbes but also germs that have fallen and are adhering to the panels and to the backsides and the gaps of the pieces of equipment installed in the room. It is adapted for use with a clean room provided with antiseptic panels and comprises one or more than one air conditioners, each having an air conditioner main body containing therein a photocatalyst so that air is fed back into the room after passing through the photocatalyst.

Abstract: An auto-response mechanism in a wireless device is switched to active only when the device is in motion and is switched to inactive when stationary. To achieve this function, the wireless device has a signal receiving part which detects and receives a signal of a waiting control channel, a control part which carries out frequency number control of a signal receiving part and a signal transmitting part, extracts received electrical field information and control channel information, and automatically completes the circuit when a call arrives. Also included is a received signal information memory part 11 which periodically stores the control channel information and the electrical field information, and a arrival signal mode memory 12 which stores the setting and cancellation of the auto-response mode.

Abstract: By making a mounting frame for a filter disposed at the front of the ceiling in a clean room of a sintered metallic material, the mounting frame obtains a structure with a strength capable of supporting the filter and with an air filtering resistance comparable to that of the filter, thereby preventing standing air in the lower part of the mounting frame and solving the problem of lowered purity of air.

Abstract: A unit for a clean room system of substantially inverted L-shaped cross section having a hollow ceiling, and a hollow wall communicating at the upper end thereof with the ceiling and at the lower end thereof with the floor in the room.= An air purifying filter is disposed at the front of the ceiling, and a cold water supplying conduit for an air conditioner control unit is located at the rear of the ceiling. A clean room system has a plurality of the units. Thus, the clean room can be simply and rapidly constructed without the necessity of a large space at the back side of a ceiling or under a floor to accommodate air conditioning ducts, thereby lowering the height of a building as compared to a conventional one, even if a 2-story or 3-story clean room is constructed. Further, the layout, such as a volume and shape in the room can be freely modified and uniform temperature and moisture can be maintained in the clean room.

Abstract: An air cleaning apparatus for a dust-free and sterile clean room necessary for an industry has a columnar body of predetermined shape having at least an air suction port and an air circulating blower, and at least a duct horizontally extending along the lower surface of a ceiling in a predetermined shape in cross section above the body. The duct has one or more clean air diffuser exits formed in a room to be cleaned for diffusing clean air into the room. This apparatus also has an air cleaning dust collector arranged between the blower and the air diffuser exits. Thus, clean air can be diffused into the room to be cleaned simply and rapidly entirely regardless of the size and the shape of the room and an already-built building. The clean room is quickly and economically constructed using the air cleaning apparatus.

Abstract: A cordless telephone utilizes internally generated identifying codes to reduce crosstalk and the risk of wiretapping. When the handset unit is mounted on the base unit, a new identifying code is automatically generated and stored in the base unit, and then transmitted to the handset unit, which also stores it. When an incoming or outgoing telephone call is initiated, the two identifying codes stored in the base unit and the handset, respectively, are compared and, if they are not identical, the telephone call is cut off. Advantageously the identifying codes are randomly generated.

Abstract: An air conditioner in which a drain pan disposed under a heat exchanger can completely collect and exhaust liquid such as condensed liquid or hot liquid and air intaken from an air intake port is passed through a ventilation passage, thereby completely air conditioning in the corners and the vicinity of a floor surface, the heat exchanger for preferably exchanging heat in a large capacity can be installed in a conditioner body and the size of the conditioner can be still constructed in small size. Thus, the air conditioner can completely condition the corners and the position near a floor surface in the room.
