Title: Air conditioner
Inventor: SUZUKI TAKASHI
IPC: F24F1/00
Filed: 1987-04-08
Abstract: PURPOSE:To efficiently conduct space cooling/heating operation without increasing blast resistance even if an air cleaning function is provided in the air conditioner by making a part of a front panel openable or closable, and providing a filter made of nets consisting of a charged non-woven cloth and activated carbon on the rear side of an openable or closable part. CONSTITUTION:A filter 5 is provided on the rear side of a front panel 4. In the filter 5, a range A is an ordinary use filter part consisting of synthetic resin nets and a range B is an air cleaning filter part consisting of a charged non-woven cloth and activated carbon nets. The suction port panel 4c of the front panel 4 allows a slide panel 4b to slide upward and open, and air to flow in as shown by arrow D. The suction port panel 4c further attracts minute dusts passing the ordinary filter A by the static electricity of the charged non-woven cloth to conduct air cleaning. Further, activated carbon cloth to conduct air cleaning. Further, activated carbon nets are allowed to absorb odors and have an effect of preventing discomfortable odor from being emitted from the discharge port of the air conditioner. Accordingly, although the air cleaning filter B is provided, since the air flow rate required for the air conditioner is secured through the ordinary filter B which does not increase the blast resistance, air cleaning can be conducted without reducing the space cooling/heating function and increasing power consumed.

Title: Color picture tube
Inventor: NAKAMURA KOUJI
IPC: H01J29/32
Filed: 1981-06-01
Abstract: PURPOSE:To make color balance of a shadow-mask-type color picture tube having an in-line-type electron gun to hardly get worse even when doming effect develops. CONSTITUTION:When electron beams bump against the entire surface of a shadow mask 3 and the temperature of the shadow mask 3 reaches to around 60 deg.C, the shadow mask 3 alters from the cold state (Ta) into the state (Tb) due to the thermal expansion, and the distance (Q) between a screen 2 and the mask 3 at the center of a panel 1a changes from (Qa) to (Qb). As the result, the position of one small hole 3a of the mask 3 moves from (Pa) to (Pb) due to the temperature rise, and doming effect develops. In order to prevent the above doming effect, the reaching points of electron beams (BB), (GB) and (RB) as indicated in figure (A) are regulated so that they include, respectively, phosphor dot or phosphor stripe trios (BS), (GS) and (RS) formed on the middle part between the center and the periphery of a fluorescent screen. As the result, glittering part of the phosphor emits light almost homogeneously without causing such unbalance as the conventional one, although a state as indicated in figure (B) is caused due to the components of the horizontal shift and the grouping shift.
