Cover member and power supply device equipped with this cover member

In a power supply device, there has been a problem that when a bus bar module to which batteries are connected varies in length, it becomes difficult to attach a cover member. The bus bar module (6) comprises: a plurality of bus bars for connecting adjacent batteries in a battery assembly body to each other, the battery assembly body being formed by stacking a plurality batteries; a main body portion (8) having the bus bars attached thereto and being stacked on the battery assembly body; a plurality of alignment projections (29) provided on the main body portion; and a plurality of locking portions (30). The cover member (1) is installed adjacent to the bus bar module along the stacked direction (X) of the batteries and comprises: a plurality of cover portions (10) for covering each of the bus bars; and an elastic deformation portion (14) for coupling the adjacent cover portions so as to be able to be mutually displaced. Each of the cover portions comprises: an alignment opening (11) into which each of the alignment projections is inserted; and a locking receiving portion (12) by which each of the locking portions is locked. The alignment opening is shaped so as to be able to be inserted even when the positions of the alignment projections move along the direction (X), thereby solving the above problem.

Optical pickup device

A quarter-wave plate and a polarization beam splitter are used as means for guiding a laser beam to first and second objective lenses. A half of the circularly-polarized laser beam incident to the polarization beam splitter is reflected in the form of an S-polarized light component by the polarization beam splitter and guided to a first objective lens, and the other half is transmitted through the polarization beam splitter in the form of a P-polarized light component and guided to a second objective lens. The whole of light quantity of the laser beam reflected from an optical disk through the first or second objective lens passes substantially through the polarization beam splitter. Therefore, the light quantity of the laser beam guided to a photodetector can be enhanced.

Device and method for forming sheet-like rubber

The sheet-like rubber forming device has a die body which has an opening having a predetermined cross sectional shape, and a variable die lip which is arranged in a front side of the die body and can change the height of the opening. The variable die lip is constructed by a first movable body and a second movable body. The die lip control unit controls the variable die lip so as to drive the first movable body in an opening direction from a state in which the first movable body and the second movable body are closed when the forming is started, hold the positions of the first movable body and the second movable body after reaching a predetermined height, and drive the second movable body in a closing direction when the forming is finished.
