Abstract: An electronic apparatus includes a plurality of contacts electrically connectable to an accessory and arranged in a first direction orthogonal to a direction in which the accessory is attached. The contacts include an attachment detection contact to detect an attachment of the accessory to the electronic apparatus, and a communication request contact for a communication request from the accessory to the electronic apparatus. The attachment detection and communication request contacts are disposed between a contact closest one end and a contact closest to another end in the first direction. The attachment detection contact is disposed between the communication request contact and the contact closest to the one end. In the first direction, a distance between the attachment detection contact and the communication request contact is shorter than that between the communication request contact and the contact closest to the other end.

Abstract: An inexpensive mechanical fuse having a high fatigue limit ratio and high rupture reliability, and superior in forming performance, and a method of manufacturing the same are presented. The mechanical fuse is composed of Fe-based sintered alloy, and comprises an inner rim 2 fixed to one power transmission shaft, an outer rim 3 fixed to the other power transmission shaft, and plural arms 4 for linking the inner rim 2 and outer rim 3, which are formed integrally. The arms 4 include rupture portions 6 which are ruptured when exposed to an overload torque. By treating in steam, an iron oxide phase is formed in the surface layer and pore inner wall. The iron oxide phase is effective to form round pores and lower the notch sensitivity. As a result, the fatigue strength and fatigue limit ratio are enhanced.
