Title: Electromagnetic cooking utensil
Inventor: NAKAMOTO TAKAAKI
IPC: A47J27/00
Filed: 1994-11-07
Abstract: PURPOSE: To suppress the extreme rise of cost and to laterally arrange a plurality of cooking utensils together without forming large spaces therebetween by making different the providing position of a fastening means on a left side surface from that of a fastening means on a right side surface. CONSTITUTION: Since the axes of a pair of machine screws 30 in their fastened conditions are spaced by a distance (d), when electromagnetic cooking utensils are laterally arranged together, the machine screw 30 provided on one side surface of one electromagnetic cooking utensil is spaced by the distance (d) and opposed to the machine screw 30 provided on the other side surface of an adjacent electromagnetic cooking utensil and is not opposed to that on the respective axes of the screw 30. Accordingly, the heads of the machine screws 30 protruding outward from the side surfaces of the electromagnetic cooking utensils do not abut against each other. The head of the machine screw 30 of one electromagnetic cooking utensil side abuts against the side surface of the other electromagnetic cooking utensil.  Thus, even if the electromagnetic cooking utensils are laterally arranged together, the spaces between these cooking utensils can be adjusted to a minimum dimension. As a result, food residue or the like can be prevented from entering between the electromagnetic cooking utensils.

IPC: F16F15/03
Filed: 1985-12-04
Abstract: PURPOSE:To enhance durability with no generation of mechanical wear, by damping a shock between a mover and a fixed member through repulsive force generated between a permanent magnet and an electromagnet. CONSTITUTION:A shock damping device is applied to a mover 6 which moves running on a fixed bed part 5a formed on a fixed member 5. If the mover 5 moves to the side of a position restricting part 5b along a guide shaft 11, the device, which actuates a control unit 9 by a detecting switch, excites an electromagnet 8. And if the mover 6 approaches the position restricting part 5b, the electromagnet 8 and a permanent magnet 12 come to repel each other. Here from the fact that repulsive force between each magnet 8, 12 is in inverse proportion to a square of distance, the device, in which the repulsive force acceleratively increases as the mover 6 approaches the position restricting part 5b, decelerates the mover 6 to be stopped at an increasing temp.

Title: Printing pressure regulator
Inventor: HIYOSHI TAKESHI
IPC: B41J25/316
Filed: 1989-10-20
Abstract: PURPOSE:To alter the driving power of a print head by rotating a lever together with a carrier shaft in response to the number of sheets to be used, regulating a print gap between the head and a platen, and outputting a detection signal in response to the rotating angle of the shaft from a rotation detector. CONSTITUTION:A carrier shaft 4 has eccentric parts 5 to be eccentrically deviat ed with respect to the axial center of an intermediate part at both ends. Since the parts 5 are rotatably and releasably supported to a side plate 3, when a lever 12 is rotated together with the shaft 4, the axial center of the intermediate part of the shaft 4 is displaced, thereby regulating a print gap between the end of a print head 1 and a platen 9. In this case, since the lever 12 is elastically engaged at an elastic piece 10 with any of engaging parts 13, it is stabilized at a predetermined position. Since the rotation of the shaft 4 is transmitted to the shaft 18 of a rotary variable resistor 17 through a sector gear 14, an idler gear 15 and a gear 16, the resistance value of the resistor 17 is varied. Thus, the driving voltage of the head 1 is varied.
