Abstract: A positioning apparatus for positioning an object in respective axis directions of an X-axis, a Y-axis perpendicular to the X-axis, and a Z-axis orthogonal to the X-axis and the Y-axis and positioning the object around the Z-axis within a plane parallel to the X-axis and the Y-axis is provided. A fastener detachably fastens the retainer. A gap is formed between a first reference surface of the retainer and the second reference surface of the fastener when a fixing shaft of the retainer is inserted into a fixing hole of the fastener, an outer surface of a pyramid part of the fixing shaft fits to an inner surface of the fixing hole and the object is positioned in the X-axis direction and the Y-axis direction.

Abstract: A cutting device for cutting a vegetable and the like including a cup-shaped lower housing, an inverted cup-shaped upper housing with a connecting apparatus for connecting these housings, a cutter disk arranged in the lower housing, and a fixing apparatus attached to the lower housing. These housings, the disk, and the fixing apparatus can be disassembled from one another. The upper housing can be detached from the lower housing by releasing the connecting apparatus. The manually operated cutter disk can be lifted and removed from the lower housing. The lower housing also can be disassembled from the fixing apparatus, which has a sucker member operated by a lever.

Abstract: This invention relates to a wood club head used for golf, and more particularly to a head in which a face insert made of brass or the like which is soft and has a high specific gravity is embedded into a main face body made of resin-impregnated carbon fibers or the like, and hard face body made of carbon resin or the like, and a face with a part of the insert exposed to the surface of the main face body is incorporated therein.

Abstract: A golf club head includes a body having a front face which is adapted to engage a golf ball, the front face being disposed at an acute angle relative to vertical when a player addresses the ball by viewing the golf club head when the golf club head is in a position to engage the golf ball. The front face has an upper edge portion which is chamfered to form a chamfer face which is disposed at an obtuse angle relative to the front face. The chamfer face has an upper edge which defines the upper boundary of the head body while the front face has a lower edge which defines the lower boundary of the head body. The chamfer face and the front face are disposed such that when a player addresses the ball, the player perceives the plane extending between the upper and lower edges as the ball-engaging plane such that the player thereby perceives the loft angle to be greater than the actual loft angle, the actual loft angle being the acute angle of the front face relative to vertical when a player addresses the ball.

Abstract: A cutting device for cutting a vegetable and the like including a cup-shaped lower housing, an inverted cup-shaped upper housing with a connecting apparatus for connecting these housings, a cutter disk arranged in the lower housing, and a fixing apparatus attached to the lower housing. These housings, the disk, and the fixing apparatus can be disassembled from one another. The upper housing can be detached from the lower housing by releasing the connecting apparatus. The manually operated cutter disk can be lifted and removed from the lower housing. The lower housing also can be disassembled from the fixing apparatus, which has a sucker member operated by a lever.

Abstract: A shaving apparatus for shaving food such as ice cubes made by a domestic-use refrigerator including a reservoir or container, a cutter blade, a rotating cylinder, and a mechanism for rotating the cylinder. The rotating cylinder can hold a large number of ice cubes and has at least one projecting portion engaging with the ice cubes. The rotating cylinder is rotatably supported about the axis thereof and is rotated by the mechanism. The ice cubes are rotated by the projecting portion of the cylinder and shaved by the carrier blade into fine slivers of ice.

Abstract: A vegetable and fruit slicing apparatus including a member for rotating an object to be sliced about the axis of the object, a cutter blade, a mechanism for moving the cutter blade. The moving mechanism moves the cutter blade along a path oblique to the rotational axis of the object, thereby enabling the object to be sliced in such a manner that only a conical or truncated-conical core remains unsliced.
