A method for manufacturing a battery is provided and including preparing the battery comprising an exterior material, the exterior material comprising a sealed portion; housing at least the sealed portion of the battery in a space portion of a chamber; providing the space portion into a pressurized state; and opening a partial portion of the battery other than the sealed portion to an atmosphere.

Method of manufacturing a battery

A rubber-metal laminated gasket material comprising a metal plate, a surface treating agent layer, an adhesive layer, and a rubber layer, the layers being sequentially laminated on the metal plate; wherein the surface treating agent layer is formed by applying a surface treating agent so that the coating amount on one surface is 30 to 1,000 mg/m, and the surface treating agent is free from chromium, has a mixing ratio of 20 to 90 wt. % of a fluorine-free titanium compound and 10 to 80 wt. % of alumina, and has a metal titanium content of 1 to 20 wt. %. The rubber-metal laminated gasket material has excellent LLC resistance under high temperature conditions.

A portable wireless sensor includes a power source, a sensor, a wireless communication circuit and a sensor control circuit obtaining data from the sensor and transmitting the data to outside through the wireless communication circuit, in which the power source includes a secondary battery, a power reception circuit receiving electric power supply in a non-contact manner, and a power source control circuit controlling charging of the secondary battery with the electric power received by the power reception circuit. The wireless sensor includes a standard mode to transmit the data obtained from the sensor to outside through the wireless communication circuit, and a diagnosis mode to diagnose at least one of the secondary battery and the sensor portion in a case where the power reception circuit receives electric power supply in a non-contact manner.

Wireless sensor

An inspection apparatus includes a chamber and a pressurizer. The chamber includes a space portion configured to house at least a sealed portion of a battery, and an opening portion configured to open a partial portion of the battery other than the sealed portion to an atmosphere. The pressurizer is configured to put the space portion into a pressurized state.

A flexible disk unit having a reduced thickness includes a spindle motor for rotating a magnetic recording medium having a magnet at its outer periphery, a movable carriage supporting a magnetic head and a stator surrounding the spindle motor and including a coil opposed to the magnet. The stator has a recess which is adapted to surround the tip of the movable carriage when the carriage is moved towards the magnetic recording medium. A head shield portion is disposed between the stator and the magnetic for shielding leakage flux in the direction of the magnetic head.

Leakage flux shielding structure of disk unit

To provide a disk unit with a reduced thickness, a motor substrate for mounting an inner rotor, outer rotor or belt drive type motor for rotating a magnetic recording medium, includes an extension portion which extends beyond the magnetic recording medium, to which electronic parts and a connector are mounted, so that they do not interfere with the magnetic recording medium.
