Title: Production of steel sheet for heat shrink band
Inventor: YAMAGAMI NOBUO
IPC: H01J29/87
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To produce a steel sheet at high yield by continuously measuring core loss value on a continuous annealing line after annealing and controlling the annealing conditions so as to regulate its yield strength to a prescribed range based on the corelation between the measured core loss value and the yield strength. SOLUTION: In a certain compsn., except the case in which crystal grains are remarkably coarsened, the core loss of the material reduces in accordance with the compositional change of unrecrystallization → partial recrystallization →grain growth in one-to-one correspondence to the microstructure. Then, the yield strength similarly changes corresponding to the structure and reduces in one-to-one correspondence to the structural change of unrecrystallization →partial recrystallization → grain growth. Since the core loss value and the yield strength are in one-to-one correspondence based on this two relations, by monitoring the core loss value of the material on line, the yield strength can be grasped with high precision.  Thus, by controlling the annealing conditions such as annealing temp., annealing time or the like so as to regulate the measured core loss value to impart yield strength in a prescribed range, the loss in the yield can be prevented.

Title: Refrigerator with ozone generator
Inventor: KOBAYASHI AKIO
IPC: F25D23/00
Filed: 1987-08-20
Abstract: PURPOSE: To prevent an ozone producer from being overheated by disposing the ozone producer on an air circulation passage, providing an air intake tube and an exhaust tube on a case of the ozone producer, facing an opening part in the air intake tube to a discharge side of the air fan, and deriving the exhaust tube from the air circulation passage to introduce it into a downstream side of a damper thermostat. CONSTITUTION: Cold air cooled in a cooler 14 is supplied to upper and lower storage chambers 6, 7 through first and second air circulation passages 17, 18. Upon cooling operation forced air from a motor driven air fan 16 is pushed into an ozone producer 31 from an expanded opening part 35 and is supplied to the lower storage chamber 7 through time exhaust tube 36. Even if the damper thermostat 28 is closed and hence an air stream on the second air circulation passage 18 stays, the air stream flows into the ozone producer 31 from the first air circulation passage 17 and is guided to a downstream side of the damper thermostat 28 through the exhaust tube 36. Thus, the cold air succesively passes through the inside of the ozone producer 31 and is prevented from being overheated without being badly influenced by the closing of the damper thermostat 28.

Abstract: PURPOSE:To provide the hot-water supplier capable of discharging hot-water from the cock thereof under a condition that the hot-water supplying operation is being stopped by a method wherein the close/open operation is effected in a predetermined period of time under a condition that the hot-water supplying operation is being effected by the output of a flow amount detecting switch detecting the existence and non-existence of outflow of water in accordance with the opening and closing of the hot-water supplying cock. CONSTITUTION:When an electric source switch 2 is closed and the hot-water supplying cock is opened normally, the flow amount of water becomes larger than the specified amount per minute and the flow amount detecting switch 3 outputs ON signal. If this signal is one time, an input proportional control valve 9 is operated based on a value set by a temperature regulating volume 8 and set temperature operation is effected. On the other hand, when the open-close-open operation of the hot-water supplying cock is effected within 4sec, the switch 3 outputs ON signal two times continuously, the control valve 9 is opened fully regardless of the volume 8 and high-temperature operation is effected. In case the cock is closed thereafter, combustion is decided to stopped. Accordingly, hot-water, stagnated in a pipeline between the machine and the cock may be used if this operation is effected immediately before finishing the use of the hot- water and energy-saving effect may be performed.
