Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a boiler system in which pressure fluctuation incident to increase/decrease in the number of operating boilers can be suppressed as much as possible by enhancing response to fluctuation of steam load. SOLUTION: A plurality of boilers 1 are installed and a steam supply passage 3 leading from each boiler 1 to a common steam header 2 is provided with a steam back flow preventer 6 and a carry over preventer 7.

Title: Culture of corn anther
Inventor: SUE NORIO
IPC: A01H4/00
Filed: 1990-11-30
Abstract: PURPOSE:To improve the reactivity of anther by transplanting a corn anther in a liquid medium and culturing under shaking. CONSTITUTION:Anther of corn is transplanted in a liquid medium and cultured under shaking. The anther is sterilized and cleaned before transplantation by immersing in 70% ethanol for 30sec and then in 0.5% solution of sodium hypochlorite for 3min and rinsing the sterilized anther with aseptic water four times. The sterilized and cleaned anther is aseptically transplanted in a medium, transferred into a culture chamber adjusted to 24-28 deg.C and cultured under shaking. The shaking is carried out either by horizontal rotation or reciprocation, preferably by rotary shaking at 20-40rpm or reciprocation shaking. The anther reactivity can be further improved by subjecting the transplanted anther to high- temperature treatment at 30-40 deg.C before introducing into the culture chamber. The high-temperature treatment may be performed under shaking culture. A callus or an embryoid is formed by the subculture for 1-3 months independent of the presence or absence of the high-temperature treatment.

Title: Preventive method for stopping circulation of refrigerant in natural refrigerant-circulation air-conditioning system
Inventor: YOSHIDA YASUTOSHI
IPC: F24F5/00
Filed: 1993-11-30
Abstract: PURPOSE:To prevent the phenomenon of refrigerant stopping its circulation due to flashing by opening a solenoid valve, when the difference in inside-pipe pressure between a supply pipe and a return pipe falls below a specific value, to make the two pipes communicate with each other. CONSTITUTION:When the pressure inside a condenser 11 falls, the boiling point of the refrigerant falls and foaming occurs in the liquid refrigerant inside the supply pipe 3 through vaporization; this impedes the descent of the liquid refrigerant and results in a decrease in the difference in inside-pipe pressures P1, P2 between the supply pipe 3 and the return pipe 4. A differential pressure gauge 51 monitors the difference in pressure and outputs a signal when it decreases below a prescribed value. By inputting of this signal a timer 52 is actuated to energize solenoid valves 21 of indoor air-conditioning apparatuses 2 and opens the valves for a specified period of time. By this opening of the valves the gaseous refrigerant which has gathered on the side of the supply pipe 3 is discharged to the side of the return pipe 4, hence recovery of the difference in pressure necessary between the pipes 3, 4 for the natural circulation of refrigerant. In this manner the phenomenon of the refrigerant stopping its circulation due to flashing can be prevented.

Title: Telling broadcasting receiver
Inventor: MASUZAWA KAZUHIRO
IPC: H04N21/439
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To set the characteristic of a speech signal easy to hear for a hard hearing person by filtering a sound signal to a prescribed frequency characteristic with a range filter and boosting the output level into more than the fixed level. SOLUTION: A range filter 8 gives filtering so as to make the frequency characteristic of the speech signal SS easy to hear for hard hearing persons and on the other hand, an amplification control circuit 9 boosts this filtering output to be more than a fixed level. Namely a speech signal on a low frequency area, which is difficult to hear for hard heating persons, is attenuated by the range filter 8 and a signal level on a high frequency range is intensified by the part of the attenuated signal power to obtain voice output easy to hear for hard hearing persons. In this case, the total sum of signal electric power from the low frequency range to the high frequency range is equal to that at the time of a flat output characteristic so that signal distortion is not generated and the articulation of sound output is not deteriorated at an amplifying output part 10.

Title: Heating equipment
Inventor: HAMAOKA SHIGEO
IPC: H05B3/00
Filed: 1989-12-20
Abstract: PURPOSE:To perform control in a short cycle by turning two or more relays ON-OFF in order with delay of a prescribed time in such a manner successively changing a relay which firstly turns OFF. CONSTITUTION:When an amount of electrification to a heater 5 is not set to zero, an amount of electrification is set by means of a signal from a variable resistor 2 by turning relay contacts 61, 62 and 63 ON. When no electrification is applied to the heater 5, either of the contacts 61 to 63 is turned OFF to judge a stop of electrification and return to the initial step takes place when the condition of stop exists. When no condition of stop exists, with relay contact 6N is turned OFF and when N is less than 3, return to the initial step takes place, and when N is more than 3 return to the initial step takes place after setting N to 1. In case when an electrification amount to the heater 5 is set to zero, either of the contacts 61 to 63 is turned OFF to judge whether or not electrification to the heater 5 is stopped and when it is not stopped, the contact 6N is turned OFF. When it is stopped, all the relays are turned OFF so that returning to the initial step may take place. In this way, heater control in a 10 to 20 sec cycle can be realized in a simple structure by the relays without requiring any special cooling construction.

Title: Radio base station
Inventor: IINUMA TOSHINORI
IPC: H04J99/00
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To provide the radio base station of an adaptive array system for preventing the generation of noise ('beegar' sound) from signals even in the case that a radio mobile station receives the signals transmitted to the other path-multiplexed mobile station. SOLUTION: In the case that the two mobile stations PS-A and PS-B are path-multiplexed, a clock generation part 52 generates a clock so as to shift the transmission time of a symbol to the mobile station PS-B for 0.5 symbol period to the transmission time of the symbol to the mobile station PS-A. By such adjustment of a transmission timing, in the mobile station, even at the time of receiving the symbol transmitted to the other path-multiplexed mobile station, since the reception time of the symbol is shifted from the reception time of the symbol to the present station, synchronization is not obtained, the received symbol to the other mobile station can not be demodulated as before and thus, meaningless noise ('beegar' sound) is not generated.
