Abstract: A pressure detection device includes a buffer member and a sensor assembly. The buffer member is deformable by a pressure change, and includes a plurality of magnets in an evenly dispersed arrangement. The sensor assembly includes at least one magnetic sensor to detect a variation of a magnetic field accompanied by deformation of the buffer member.

Abstract: The brushless electric machine includes a first drive member (30U) having a plurality of permanent magnets (32U); a second drive member (10) having a plurality of electromagnetic coils and capable of movement relative to the first drive member (30U); and a third drive member (30L) disposed at the opposite side from the first drive member (30U) with the second drive member (10) therebetween. The second drive member (10) has magnetic sensors (40A, 40B) for detecting the relative position of the first and second drive members. The third drive member (30L) has at locations facing the permanent magnets of the first drive member (30U) a plurality of magnetic field strengthening members (32L) for strengthening the magnetic field at the location of the second drive member (10) in conjunction with the permanent magnets.

Abstract: A timepiece construction member comprises a timepiece frame, trains, a motor, circuit member and so on. A supporting member for keeping and securing the timepiece construction member is made of a spring plate. The supporting member is engaged with the plate at the periphery thereof and as a result, the timepiece construction member is secured by a simple means. It is possible to provide a securing construction having a high reliability and a small number of members. Further, since the supporting member also serves as the other operating member such as a battery plus terminal, it is possible to provide a small sized securing construction for members. Furthermore, since the members of the timepiece are in contact with an elastic beam of the spring plate, the members of the timepiece can be secured stably.
