Abstract: There is described prevention of an increase in the thickness of an oxide film of a silicon wafer, which would otherwise be caused by eruption of gas from a CVD oxide film of another wafer during the course of a high-temperature annealing operation. A semiconductor device, which has a silicon substrate and trench isolation structures for isolating a plurality of active regions from one another, is manufactured by the steps as follows. A first and a second dielectric films are formed on the silicon substrate of one of the conductivity types. The dielectric films are removed from the areas of the silicon substrate where the trench structures are to be formed. The trench structures are formed in the uncovered areas of the silicon substrate to a predetermined depth. An oxide film is deposited into the respective trench structures by means of CVD after the oxide film has been deposited on the interior surface of the respective trench structure.

Abstract: A sealed rectangular battery has a conductive battery case including an external casing and a sealing cap. The external casing encloses a generator element and is sealed by attaching the sealing cap using heat. The battery includes an electrode terminal with an opposite polarity to the battery case, and a safety valve. The safety valve includes a cap that is charged with the same polarity as the battery case and a valving element that covers a vent hole. The electrode terminal and safety valve are provided separately at different positions on the battery case. This construction is simpler than conventional batteries where the safety valve is integrally formed with an electrode terminal, which means that the electrode terminal can be miniaturized. This battery also has improved internal resistance.

The balance weight is composed of a magnet, and is attracted to the end surface of the recording drum by its magnetic force. The two balance weights are arranged at a predetermined attaching angle such that an unbalance force caused by centrifugal forces developed by a plate and a movable clamp, for example, is canceled.

Abstract: In a rectangular alkaline storage battery, the sides of negative cores of negative electrode plates 10, which are disposed at the outermost positions of the group of electrode plates and oppose an outer casing can 40, are exposed. The pore ratios (ratio of total area taken up by pores to area of electrode plate) of the exposed cores must be made lower than those of the other unexposed cores. The pore ratio of the exposed negative core is specified as falling within a range of 10% to 40%.

Further, there can be obtained a large rectangular alkaline storage battery which has superior permeability for a gas which would arise in the battery, an improved capacity ratio, and greater volumetric energy density.

Abstract: A battery structure is arranged such that an elastic valve body or the like cannot easily come off from the cover body during the production of the battery, which thereby enhances the production yield. A cover body of the invention includes a flange portion airtightly fixed to an injection port and a bulge portion protruding from the flange portion and provided with a space in which an elastic valve body is fitted (mounted).

Accordingly, the elastic valve body can be prevented from coming off from the cover body due to vibration developed during the transportation of the cover body or like occasions, making it possible to enhance the production yield.
