Patent JP-2000266446-A (JP)
Title: Using method of freezer/refrigerator
Inventor: HIRAOKA TOSHIE
IPC: F25D17/08
Filed: 2000-03-10
Abstract: PROBLEM TO BE SOLVED: To preserve a food while suppressing degradation by making a switch to a storage compartment of temperature zone above the maximum ice crystal generation zone and above the freezing temperature zone, i.e., a new temperature zone freezing compartment, thereby prolonging the preservation period of food as compared with an ice box. SOLUTION: Chill is supplied through a new temperature zone freezing compartment air duct to a new temperature zone freezing compartment. A temperature detecting thermistor (temperature detecting means) is disposed in the new temperature zone freezing compartment. When the temperature detecting thermistor exceeds a specified temperature, a chill outlet is opened by opening a damper and temperature in the new temperature zone freezing compartment is regulated by supplying chill. Since foods in the new temperature zone freezing compartment are preserved in a temperature zone from -5 deg.C to -10 deg.C, for example, the foods are not frozen hard as in case of freezing compartment but frozen soft enough to be cut by means of a kitchen knife or a hand. Furthermore, foods can be preserved for a week or longer under better conditions as compared with an ice box.

Title: Mounting structure of resin molded product and method for molding resin wokded product
Inventor: HIDAKA TOMOAKI
IPC: F16B2/20
Filed: 2000-03-22
Abstract: PROBLEM TO BE SOLVED: To perform reutilization of a resin molded product without performing a process to separate a different kind of a material when a resin molded product is recycled. SOLUTION: A clip material 4 to hold a fixing member 8 made of a metal is insert-molded on a mounting surface 1A of a rear spoiler 1 made of synthetic resin.

Abstract: PROBLEM TO BE SOLVED: To measure the flow velocity and the flow rate of a fluid to be measured, with high accuracy. SOLUTION: A flowmeter 10 measures the flow rate on the basis of the flow velocity, which is measured by the flow-velocity measuring apparatus 12.
