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.

Liquid crystal display, method for producing liquid crystal display, and electronic apparatus

A liquid crystal display includes a pair of substrates, a liquid crystal layer being held by the pair of substrates, a first electrode and a second electrode that drive the liquid crystal layer, and a driving element that controls the driving of the first electrode, the first electrode, the second electrode, and the driving element being disposed on one of the pair of substrates. The one of the pair of substrates includes a resin film, an overlying film disposed on the resin film, the first electrode being disposed on the top surface of the overlying film, an electrode insulating film covering the first electrode, the second electrode being disposed on the top surface of the electrode insulating film, a connection electrode disposed on the electrode insulating film and connecting the first electrode to the driving element, and a connection line disposed below the overlying film and connected to the second electrode. The connection electrode is connected to the first electrode through a first through hole passing through the electrode insulating film and is connected to the driving element through a second through hole passing through the overlying film and the electrode insulating film. The second electrode is connected to the connection line through a third through hole passing through the overlying film and the electrode insulating film.

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.
