Title: Air conditioner
Inventor: NISHIKAWA KATSUTOSHI
IPC: F24F13/22
Filed: 1990-06-22
Abstract: PURPOSE:To enable a smooth discharging of dew to be attained and eliminate a dew dripping from a dew receptacle by a method wherein a dew receptacle held horizontally until a specified amount of dew is accumulated, and a lower dew receptacle pan having a discharging port at a downstream side are provided. CONSTITUTION:Dew from a heat exchanger 6 is dropped onto a rotary dew receptacle pane 16 and accumulated there. Dew from another part is mainly dropped onto a balanced weight 21 of plate form, where the dew is flowed into the rotary dew receptacle pan 16. Dew is full in the rotary dew receptacle pan 16 and becomes heavier than the balanced weight 21, resulting in that a large amount of dew in the dew receptacle pan 16 is once flowed down into a lower dew receptacle pan 17 under a sea-saw rotation thereof. The dew is flowed from a discharging port 24 into the water drain pipe and discharged. At this time, a large amount of dew is flowed once into the drain pipe, so that a pressure at that time is sufficiently high. Due to this fact, even if the air lock is found in the pipe, this is not prohibited by it and the dew may smoothly be flowed in the drain pipe and discharged out of a room.

Title: Production of barium titanate powder
Inventor: TANAKA YASUSHI
IPC: C01G23/00
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To efficiently obtain barium titanate powder having a slight particle diameter dispersion by solid phase synthesis by firing a mixture contg. BaCO3 powder and TiO2 powder each having a specified specific surface area. SOLUTION: A mixture of BaCO3 powder having <=10 m<2> /g BET specific surface area with TiO2 powder having >=15m<2> /g BET specific surface area is fired at 1,000-1,200 deg.C for 2-4 hr to obtain the objective barium titanate powder having a particle diameter dispersion δ/χ (δ is standard deviation and χ is mean value) of <=0.3. Since BaCO3 particles are enclosed with TiO2 particles and BaCO3 -rich parts are not fired, the grain growth of the BaCO3 power is suppressed. Since the BaCO3 and TiO2 powders react uniformly, the particle diameter dispersion of the formed barium titanate powder can be reduced. The control of particle diameter dispersion is facilitated by using BET specific surface area that is a relatively easily controllable physical quantity as a factor for controlling particle diameter dispersion.

Filed: 1978-12-27
Abstract: PURPOSE: To prevent the head of a thermal printer from damaging by retaining and detecting dot information by a recording time control circuit and altering the recording time to retain the temperature at the surface of the head constant.  
     CONSTITUTION: When the previous dot information is retained in a latch circuit R1 and next dot information is applied to an input terminal T1, that is, the output a of the latch circuit R1 is "1" and DATA1 at the input terminal is "1" (See a timing chart A.), the output b of a comparator X1 becomes "0". When the select signal S1 is "0" at recording time, the output "0" at the output b of the latch circuit X1 is produced at the output OUT1. When the select signal S1 is "1", the outpt "1" of dot information DATA1 is produced at the output terminal T5. As a result, only when the select signal S1 is "1", a current is applied to a thermal elements. When this printer records the previous dot information, it shortens the recording time by considering the temperature rise at the head, while when this printer does not record the previous dot information, it retains the normal recording time as predetermined.
