Patent JP-S63251740-A (JP)
Title: Range hood
Inventor: MATSUMURA TSUNEO
IPC: F24F7/06
Filed: 1987-04-06
Abstract: PURPOSE:To forcibly introduce smoke generated above a cooking table without diffusing the smoke throughout the indoors, by a method wherein a fan for ventilation and an indoor air circulating fan for forming an air curtain to prevent diffusion of the smoke and the like throughout the indoors are mounted in the hood body in a manner to be separated away from each other. CONSTITUTION:With a motor 20 charged with electricity, a fan 18 for ventilation and an indoor air circulating fan 19 run. The fan 18 for ventilation collects a rising air flow from a cooking table 6, and is exhausted through an exhaust port 14 and a ventilation port 4 to the outdoors 3. Meanwhile, through drive of the indoor air circulating fan 19, indoor air is sucked through a suction part 17 on the top of a hood body 11 and is discharged obliquely downward through a discharge port 15 to form an air curtain 16. Thus, a rising air flow, being about to diffuse throughout the indoors 2, is prevented from diffusing because of the air curtain 16, and is collected in a suction port 13, and is exhausted to the outdoors.

IPC: A23L17/60
Filed: 1980-06-21
Abstract: PURPOSE: To accumulate laver sheets in a container can in a regular manner without bending a soft peeled laver sheet in the delivery condition, by delivering a formed laver sheet peeled in a laver sheet peeling machine in a state in which the central part is low in the delivery direction and the both ends are warped high upward.  
     CONSTITUTION: Both top ends of a reed screen 14 with a formed laver sheet held by reed screen holding belts 11 and 12 detour a deyouring roller 13 to the left, and the top central part of the reed screen 14 is made to detour around a detouring lever 30 to the left, and held by reed screen pulling rollers 7 and 8. The central part of the reed screen 14 which detours around the lever 30 is pulled from the top thereof while being made to detour around the lever 30, and the formed laver sheet 43 is peeled from the central part of the screen 14. The peeled laver sheet 43 is directly lifted and brought into contact with a laver sheet guide roller 35, and the laver sheet 43 is separated from the screen 14 by the rotation of the roller 35 in the direction (b) and pressed to a rotating cylinder 2. The laver sheet 43 is then transferred in a warped state in which the central part is lowered by a central support plate 41 and rollers 39 and 40 and both sides are lifted by side supporting plates 42, delivered to a container can and accumulated.

Title: Heating cooker
Inventor: TANAKA TERUYA
IPC: F24C7/02
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a heating cooker in which power consumption is reduced. SOLUTION: A door 14 is fixed rotatably to the front end part of a cooking chamber 13 in order to open/close the cooking chamber 13 and the door 14 is provided with a heat insulating window 35. Since an evacuated heat insulating layer 40 is formed between the front and rear glasses 37, 38 of the heat insulating window 35, heat insulation of the cooking chamber 13 is enhanced and power consumption of heater cooking is reduced. Furthermore, a spacer 39 is prevented from being melted with microwave or heat to cause collapse of the heat insulating layer 40 because a metallic spacer 39 is interposed between the front and rear glasses 37, 38.

Title: Antenna in common use for two-frequency
Inventor: WATANABE HIRONOBU
IPC: H01Q5/00
Filed: 1985-04-23
Abstract: PURPOSE:To obtain an antenna which has a high gain to both frequencies by specifying the length of a phase coil. CONSTITUTION:Linear parts 11a-11d contribute to radiation and phase coils 12a and 12b and a phase coil 13 remove opposite-phase components so that they do not contribute to radiation. The length of the phase coil 13 is set to 0.05-0.2 lambda, where lambda is the wavelength of low frequency. Consequently, the coil increases in pitch as compared with conventional coils. Namely, the length is >=10cm when the wavelength is 2m. When the length of expansion equivalent electrically to 1/2 wavelength is 80cm and the diameter is 3cm, the coil has 11 turns, so when the length is set to 10cm, the coil pitch is a little bit smaller than 12mm and the winding density is made large, thereby reducing the interwire capacity, etc., as compared with a coil which is wound closely. The winding diameter of the phase coil is restricted by the internal diameter of a pipe, etc., and preferably less than <=0.015 time the wavelength lambda.

Filed: 1989-04-06
Abstract: PURPOSE:To prevent low temperature hot water from entering a nuclear reactor and make possible relaxation of heat fatigue of a water feeding nozzle part by providing a control mechanism for allowing the operation of a reactor purification system to stop by the generation of a turbine trip signal to stop automatically. CONSTITUTION:When a turbine trip generates, a turbine trip signal 17 is transmitted to a controller 16, a water feed heater 5 loses a heating function by closing a turbine stop valve 2 at this time and low temperature water stays by reactor water in water feed tubing 6. In addition, just before water feed stop, a water feed flow low signal 18 is input in the controller 16 from a water feed flowmeter 15, thereby the controller 16 is allowed to stop a reactor purification pump 11 to output signals 19, 23 allowed to close a water feed injection gate valve 13 so as to prevent reactor purification system return water of high temperature from entering tubing 6 in which low temperature feed water stays. And since the more temperature difference between high temperature reactor water and low temperature injection water are, the more serious thermal fatigue of a water feed nozzle 7 and a sparger 8 are, the control mechanism for shortening an inflow time of low temperature water is allowed to contrive the reduction of the thermal fatigue.
