Abstract: A coin type (button type) electrochemical cell is configured of a negative electrode can configuring a negative electrode side and a positive electrode can configuring a positive electrode side. Then, the negative electrode can and the positive electrode can are formed of non-magnetic stainless steel which does not have magnetic properties due to plastic processing. Specifically, the negative electrode can and the positive electrode can are formed by using high manganese stainless steel or SUS305 having a high nickel (Ni) content. In this way, the negative electrode can and the positive electrode can are formed of non-magnetic stainless steel which maintains non-magnetic properties even after being processed into the shape of a coin, and thus it is possible to provide a non-magnetic electrochemical cell, and as a result thereof, it is possible to provide an electrochemical cell which is not affected even at the time of being arranged in the vicinity of a magnet.

Abstract: A timepiece which can secure a sufficient waterproof performance and which can transmit sound from a sound source efficiently to the exterior is provided. The timepiece is equipped with a movement, a timepiece case accommodating the movement, and a hollow structure portion having a connection proximal portion directly or indirectly in contact with the movement. The hollow structure portion is formed such that a space defined between itself and the timepiece case is of a hermetic structure. The inner space of the hollow structure portion communicates with the external space via an external opening of the timepiece case.

Abstract: A semiconductor device uses a lead frame, in which an outer lead is electrically connected to an inner lead suspension lead via an inner lead. An encapsulating resin covers the inner lead and part of the outer lead, and a plated film is formed on an outer lead cut surface so that a solder layer is easily formed on all surfaces of the outer lead extending from the encapsulating resin. The inner lead suspension lead includes a narrowed portion that is smaller in cross-sectional area than other portions of the inner lead suspension lead to suppress impact forces generated when the inner lead suspension lead is cut.

Abstract: A bearing device includes a shaft and a roller bearing externally inserted over the shaft. The roller bearing includes an inner ring disposed coaxially with a center axis of the shaft, an outer ring surrounding the inner ring from an outer side in a radial direction, and a plurality of rolling elements held between the inner ring and the outer ring to be capable of rolling. The inner ring includes an inner ring one half section disposed on one side in an axial direction and an inner ring other half section disposed on the other side in the axial direction. The inner ring one half section is in contact with the rolling elements from the one side toward the other side in the axial direction. The inner ring other half section is in contact with the rolling elements from the other side toward the one side in the axial direction. Preloads are applied to the inner ring one half section and the inner ring other half section in directions in which the inner ring one half section and the inner ring other half section come close to each other.

Abstract: A mechanical component configured to rotate with a shaft member includes a component main body having a through-hole through which the shaft member is passed, and one or more shaft support portions formed on the inner surface of the through-hole to fix the shaft member to the component main body. The one or more shaft support portions protrude from the inner surface of the through-hole and are capable of retaining the shaft member due to an elastic force. The one or more shaft support portions are made of material having a larger elongation percentage than that of the material of the component main body thereby preventing breakage of the mechanical component due to stress created when the shaft member is forced through the through-hole in the component main body.
