Abstract: PURPOSE:To obtain an output corresponding to a torque by providing an input shaft and an output shaft which are coupled each other via a torsion bar with a long gear, a short gear of a first detecting ring and a short gear, a long gear of a second detecting ring respectively in a confronting manner. CONSTITUTION:Detecting rings 11, 12 have a plurality of long gears 11, 12a, and short gears 11b, 12b, respectively. An end of the long gear of the detecting ring is confronting to an end of the short gear of the confronting detecting ring. The positional relation of the long and short gears is set so that the width of the confronting gears is 1/2 the width of the gear when the twist of a torsion bar 7 is zero. When a torque is impressed to a transmission shaft 2 (input shaft 5, output shaft 6), the bar 7 is twisted. The rings 11, 12 are shifted relatively because of the twist. The confronting width of the gears is changed due to this shift of the rings, and the impedance of detecting coils 21, 22 is changed corresponding to the change of the confronting width. As a result, it becomes possible to obtain an output corresponding to the torque given to the transmission shaft 2.

Title: Housing device for electronic device structure
Inventor: SHIMADA MITSUHIRO
IPC: G06F1/16
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a physical failure even in a state where a card is partly jumped out of a housing device by covering and protecting the outside of the card protruded from a card slit via a guard part. SOLUTION: When an IC memory card 12 is inserted through a card slit, the card 12 moves in a guard member 14 and hits a sensing pin 28. Thus, a link bar 23 is turned against the force of a spring 24 with a pivot 26 defined as a fulcrum. Meanwhile, the member 14 is pushed out to the 'card position' in response to the turning of the bar 23 and then locked by a release means 25. As a result, the card 12 is electrically connected to the main body 11 of a housing device. In this state, about half of the card 12 is protruded to the outside and the outside of the card 12 is protected by the member 14 which is protruded from the main body 11. Therefore, the unnatural external force is never directly applied to the card 12 and accordingly the physical failures of the card 12 can be prevented.
