Abstract: An exercise assisting device includes a table shape body configured for a user to step on, a main body which supports the table shape body from below, and a hold body which is arranged on the main body. The hold body is configured to hold a trunk of the user as the user steps on the table shape body and a center of gravity of the user is positioned more forward of a step position provided on the table shape body. The exercise assisting device is configured to move the table shape body relative to the main body and/or the hold body relative to the main body while regulating a forward inclination of the user as the user uses the device.

Abstract: An exercise assisting device includes a table shape body which a user steps on, a main body which supports the table shape body from below and a hold body which is arranged on the main body. The hold body holds a trunk of the user who steps on the table shape body and whose the center of gravity is positioned forward of a step position of the user. The exercise assisting device regulates a forward inclination of the user while moving relatively the table shape body and/or the hold body to the main body.

Abstract: To provide an intellectual training toy which can suppress noise and improve safety, and which has a significant effect on developing children's intellect, maintaining or recovering the mental and physical functions of the elderly, and other purposes. An intellectual training toy whose material is a soft elastic material comprises a triangular annular member (1), wherein a user can turn an inside surface and an outside surface of the annular member (1) inside out, and the shape of the annular member (1) changes when the user turns the inside surface and the outside surface of the annular member (1) inside out. Since the intellectual training toy is made of a soft and pliable material, noise can be suppressed and safety can be improved.

Abstract: An inspection device in accordance with the present invention is configured so that a light source used for irradiating light, and a reflection-type prism that irradiates the light from the light source to a hologram provided on an inspection target that is placed downward and that diffracts light rays in different directions that are reflected from the hologram upward in the same or substantially the same direction are housed in a case. With such an arrangement, it becomes possible to provide an inspection device that can positively conduct an inspection process for identifying the genuineness of an inspection target having a hologram quickly, and is also advantageous in costs.

Abstract: A housing for accommodating at least one disk-shaped recording medium such as an optical disk includes at least one holder having means for holding a recording medium. At least one cover is arranged closely adjacent the holder in parallel relationship such that the covers alternate with the holders so that one end face is made up of a holder, on which an end plate is mounted. A first fastener means is received in openings provided in the holders, covers and end plate. A second fastener means is received in another openings provided in the covers and end plate.

Abstract: Upper lens formed of a portion of a sphere having radius R.sub.2 and lower lens formed of a portion of a sphere having radius R.sub.1 are manufactured integrally by molding for forming the lens of eyeglasses Radii R.sub.1 and R.sub.2 are slightly different from each other, so that the front view comes into eyes through lower lens when the user is in a normal posture, while the front view comes into eyes through upper lens when the user bends forward.

Abstract: A method of producing a non-oriented electromagnetic steel strip by subjecting a low-carbon steel slab to hot-rolling, cold rolling at a small reduction and first annealing. In order to improve magnetic flux density and surface appearance of the product, specific conditions are employed so as to coarsen the crystalline structure to obtain a controlled and moderate crystal grain size after the annealing. The slab is cold-rolled at a rolling reduction of about 5 to 15% and is subjected to first annealing by heating at a rate of about 3.degree. C./sec or higher and holding the strip for about 5 to 30 seconds at 850.degree. C. to the A.sub.3 transformation temperature of the steel, while controlling the crystal grain size to about 100 to 200 .mu.m after first annealing.

Abstract: A method of producing a grain oriented silicon steel sheet is adapted to lower the iron loss. A silicon steel slab, containing about 2.0 to 4.0 weight % of Si and an inhibitor-forming amount of S, or Se, or both, is hot rolled. After the hot rolled steel sheet is annealed when necessary, the steel sheet is cold rolled into a cold rolled steel sheet having a final thickness by performing cold rolling either one time or a plurality of times with intermediate annealing therebetween, the cold rolled steel sheet then being subjected to decarburization, coating of the surface of the steel sheet with an annealing separation agent mainly comprising MgO, secondary recrystallization annealing, and purification annealing. In the cold rolling step, an oxide layer exists on the surface of the steel sheet. Specifically, in the cold rolling step, rolling oil is supplied only at the entrance of the rolling mill used, and an oxide layer having a thickness of about 0.05 to 5 .mu.m is generated.
