Title: Lock mechanism for cover
Inventor: SAWAUMI MITSUO
IPC: G03B17/02
Filed: 1988-09-19
Abstract: PURPOSE:To weaken the rigidity of a pawl part and to improve operability at the time of releasing locking by constituting the title mechanism so that a 2nd engaging part may bite with a 1st engaging part when the force in an opening direction is added to a cover which is locked by the 1st and the 2nd engaging parts of the pawl part. CONSTITUTION:When a battery cover 10 is made to slide in a direction shown by an arrow B, a tapered part 10B on the leading edge of the cover 10 runs onto the tapered part 12B of a pawl 12 to press the pawl part 12 downward. By closing the cover 10 after it is made to slide more in the direction of the arrow B, the leading edge of the cover 10 gets over the pawl part 12 and the pawl part 12 returns to an original position. The engaging part 10A of the cover 10 engages with the engaging part 12a of the pawl part 12 and the cover 10 is locked. Then, the moment of FXl is added to the base end part 13 of the pawl part 12 by applying external force F in the same direction as the opening direction of the cover 10 to the engaging part 12B through the engaging part 10B. The pawl part 12 is bent with the moment so that the engaging part 12B bites with the engaging part 10B. Therefore, the rigidity of the pawl part 12 can be weakened since locking is not easily released. Then, the operability of a locking releasing button 14 can be improved.

Title: Electromagnetic clutch
Inventor: SUZUKI SHINICHI
IPC: F16D27/112
Filed: 1987-09-16
Abstract: PURPOSE:To increase the transmission torque of an electromagnetic clutch in an early stage of use by a simple treatment and to hold it in a stable state thereafter by applying magnetic grains and nonmagnetic grains in a mixed state on transmission/friction faces. CONSTITUTION:Mixture consisting of Fe magnetic grains and SiC nonmagnetic grains with average grain diameter about 0.5mum is manually applied on transmission/friction faces 14a, 32a. As a result, the transmission/friction faces 14a, 32a remarkably increase their catching resistances through the mutual bite of grains themselves due to the interposition of both grains, specially high hardness nonmagnetic grains, infiltrating into the recesses of those surfaces. Improvement in fight adhesion property due to the interposition of, principally, the magnetic substance filling up the gaps at interfaces makes molecular force very strong and also decreases the leak of magnetism produced due to the gaps at the interfaces to reinforce magnetic flux, i.e. electromagnetic attracting force. Such operations can remarkably improve the transmission torque of an electromagnetic clutch in an early state of less familiarized use, and also this condition can be maintained in a stable state thereafter.
