Abstract: A storage case includes a front cover. An upper side of the front cover is rotatably connected to a top plate via a hinge structure. An outwardly protruding locking convex part is formed on the upper side of the front cover. In a first opened state where the front cover is turned upward about the upper side of the front cover as an axis, the locking convex part comes into contact with an engagement part on the top plate. When the front cover is turned upward from the first opened state and becomes in a second opened state in which the engagement part passes over the locking convex part, the locking convex part engages with the engagement part so that the front cover is locked in the second opened state. The locking convex part is recessed from a rear side of the front cover to be in a shell-shaped form.

Abstract: The electric kitchen knife has blades (2) connected to the front end of a main housing (5), and the blades (2) move in reciprocal motion to cut food. The main housing (5) has a stand leg (6) projecting from the bottom surface positioned away from the center of gravity towards the blade end. The stand leg (6) maintains the main housing (5) in an upright standing position. Held by the stand leg (6) in an upright standing position on a table (7), the front end of the main housing (5) is raised separating the blades (2) from the table (7).

Abstract: The food holder has two vertical plates, mounted on a base vertically and parallel to each other. The two plates create a gap between the plates where food is held. Knife guides with vertically extending guide slits are provided at both ends of the gap. The two vertical plates are connected to the base in a manner allowing their translational motion in directions which can change the gap size. Additionally, a centering mechanism insures the distance moved by each plate is equal.

Abstract: In a thermal-environment sensor which detects thermal conditions in an indoor environment based on the surface temperature of a heating element supplied with a thermal quantity, the spectral emissivity of the outer surface of said heating element closely conforming to the spectral emissivity of the surface of the human skin or clothes thereon so as to bring the radiant heat transfer coefficient of the sensor remarkably near that of the human body.
