Inventor: KOSAKA YOSHIO
IPC: H01B3/12
Filed: 1991-04-16
Abstract: PURPOSE:To achieve a laminated ceramic capacitor which does not degrade in resistance and remains highly reliable for a long time by using, as dielectric material, lead composite perovskite the oxygen vacancy of which has been substantially reduced by introducing oxygen after firing, and forming internal electrodes from copper. CONSTITUTION:Lead composite perovskite is used as dielectric material and internal electrodes are formed from copper to manufacture a laminated ceramic capacitor. After the lead composite perovskite is fired in a reducing atmosphere in the manufacture process, oxygen is introduced on the conditions expressed in the formulae (where Po2 is oxygen partial pressure (atmospheric pressure), T is processing temperature ( deg.C), and t is processing time (hr); however, 550<=T<=980), to reduce the oxygen vacancy due to reduction. The initial high resistance of the resultant ceramic capacitor does not degrade for a long time, which makes the capacitor reliable.

Title: Ventilating of air conditioner
Inventor: KOBAYASHI SHIGETADA
IPC: G21F7/00
Filed: 1986-05-15
Abstract: PURPOSE:To provide the title air conditioner capable of removing tritium generated in a room to be air-conditioned, small in size and requiring a small installation space, by disposing a catalyst for removing tritium in the air conditioner or a circulating pipe. CONSTITUTION:An air conditioner 5 comprises a coarse filter 6, a cooling coil 7, a heating coil 8 and a catalyst 17. Atmospheric air flowing into the air conditioner 5 is first deprived of dusts such as fine particles by the coarse filter 6, and is then passes through the cooling coil, in which it is dehumidified by a cooling condensation process. The dehumidified air is heated by a heating coil 8, and then makes contact with the catalyst 17, whereby elementary tritium is converted into an oxide vapor. The air thus treated is fed to a humidifier 4, in which it is diluted by the addition of water vapor. The air thus cleaned and conditioned is returned into a room 1 to be air-conditioned. Tritium water vapor is removed through condensation upon making contact with the cooling coil 7. Since there is no need for separately providing a tritium cleaning equipment, this system is economical, requires a small installation space, and does not require a large amount of the catalyst.

Title: Horn structure for slot array antenna
Inventor: MATSUMOTO SHIGERU
IPC: H01Q13/02
Filed: 1994-04-27
Abstract: PURPOSE:To improve the directivity on the vertical plane of an antenna without increasing the length of a horn nor providing a dielectric plate by placing a metallic plate in the horn to divide the electromagnetic wave propagated in the horn. CONSTITUTION:The electromagnetic wave radiated from a slot array antenna 1 undergoes the elimination of its orthogonal polarized wave component by a subpresser plate 3 and reaches a metallic plate 4. The plate 4 functions as the deformed Y branch by means of the upper and lower metallic plates 2a and 2b which construct a horn part 2. Thus the electromagnetic wave that hit the plate 4 is divided into two waves on a magnetic field surface. These divided waves reach the metallic plates 5a and 5b respectively and divided gain there. Then the divided waves are synthesized at a place near the horn opening part. The electromagnetic waves passing through between the plates 28 and 5a and between the plates 5b and 2b have the same phase and the same amplitude. The phases and amplitudes of these electromagnetic waves are approximately equalized to those of the electromagnetic wave which passes through between the metallic plates 5a and 5b by adjustment.
