Title: Low temperature cold water supplier
Inventor: NISHIYAMA YOSUKE
IPC: F25D13/00
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To continuously deliver cold water of about 0 deg.C, and eliminate the possibility of an apparatus from being damaged owing to freezing by detecting by detector partial freezing caused by cooling of water, and melting the partial freezing of a cooling line with freezing removal means. SOLUTION: A refrigerant line 2 and a cold water line 3 are disposed via a heat exchanger 1, and a detector 4 is provided for detecting partial freezing of the cold water line 3, and further freezing releasing means 5 is provided for releasing the partial freezing. For example, when set temperature of the heat exchanger 11 is set to about 0 deg.C, and then water is flowed to the cold water line 3, while circulating a refrigerant on the refrigerant line 2, the water is cooled through the heat exchanger 1 to obtain the water of about 0 deg.C. In this case, partial freezing happens in the course of the cold water line 3, and when a set flow rate is or lower reached, a signal from a flow rate sensor is sent. When the signal is received, the freezing releasing means 5 is actuated for melting the partial freezing in the cold water line 3.

Abstract: PURPOSE:To change easily blowing direction to a desired one by providing a support on a base having a spherical lower surface and a head having a blowing blade while providing a weight member pivoting about the support along with the rotation of the blowing blade. CONSTITUTION:When a weight member 13 is in the position shown in the drawing, the center of gravity G is located behind the center of a support 2 to incline rearward the whole fan and direct upward a blowing blade 5. When a switch 14 is operated to provide the running state under such a condition, the blowing blade 6 is rotated by a motor 8. Also, the rotation of motor 8 rotates a movable strut 4 through reduction gears(9, 11, etc.) with proper speed clockwise for example and pivots a rod 12 in the same direction. Thus, since the weight member 13 pivots about the support 2 in the same direction, the position of center of gravity G is changed pivotally in the same direction and the whole fan is oscillated since the lower surface of base 1 is formed spherically so that the blowing direction is automatically changed left, right, upward and downward.

IPC: B41J2/045
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To achieve a drastic high recording speed by absorbing a irradiated light beam and converting the same to heat by a heat converting means, heating a liquid in a liquid room so as to be vaporized, causing deformation of partition wall by the volume expansion of the liquid room for forcing an ink into a pressure room and pressing the ink so as to be jumped from a nozzle. SOLUTION: A laser beam irradiated to an exposed part 15 of a heat conductive layer 14 via a light irradiating opening 30 is absorbed so as to be converted to heat. The liquid inside a liquid room 32 is heated by the heat instantly so as to partially vaporize the liquid to expand the volume of the liquid room 32. According to the volume expansion, a partition wall 18 is deformed so as to be forced to an ink pressure room 34 side for pressing an ink so that ink droplets are jumped from a nozzle 42. The ink droplets are attached onto a recording paper so as to form dots for recording an image by the dots. After finishing the laser irradiation, the bubbles inside the liquid room 32 is cooled down so that the partition wall 18 regains the original shape.  By the negative pressure generated in the ink pressure room 34 and the capillary phenomenon, the ink is charged to the ink pressure room 34.

IPC: F24H9/00
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To reduce cost of a heat-exchanging heater for heating a body to be heated by passing a heating medium through a single tube type heat- exchanging tube by using the air, being heated up by a combustion flame sucked into the heat-exchanging tube, as the heating medium thereby enhancing the thermal efficiency while reducing the use of a heat source. SOLUTION: When a heater 11 is used, a combustion flame F is generated from a burner 19 disposed on the heating medium inlet side of a heat-exchanging tube 13. The air is then blown into a T-shaped tube part 15 through an air nozzle 17 provided at one end opening of the T-shaped tube part 15. Consequently, the air in the T-shaped tube part 15 moves out therefrom to produce an air flow. The air flow pulls the air in the heat-exchanging tube 13 toward the T-shaped tube part 15 along with the combustion flame F generated from the burner 19, and the air warmed by the combustion flame F spreads entirely in the heat-exchanging tube 13. Consequently, liquid, gas, etc., can be warmed by the air spreads entirely in the heat-exchanging tube 13.

Title: Video signal processing circuit
Inventor: MATSUMOTO HIROAKI
IPC: H04N9/72
Filed: 1987-10-23
Abstract: PURPOSE:To relieve the adverse effect of a random noise in the case of demodulation by applying level clamp when no noise is detected in a carrier video signal and not applying it when any noise is detected. CONSTITUTION:An FM luminance signal Yf is fed to a limiter 11 from one output terminal of a signal branch circuit 37 and fed to a demodulation section 12 and a noise detection section 39. The detection section 39 compares the detection output Sa of the carrier envelope detector 40 with a reference voltage level Vr by a level comparator 41 to output a signal Sb. The signal Sb is at a high level when the signal Yf is a normal signal component and at a low level by a noise part and the supply of the luminance signal to the clamp part 43 is turned on/off via a switch 44. Thus, even in the case of including noise part such as the variable-speed reproduction mode, the adverse effect that the demodulated random noise appears as the level reduction of the video signal is reduced.
