A sealed battery cell including an anti-explosion mechanism disposed between an electrode group and a top cover, and that deforms or cleaves due to elevation of internal pressure in the battery cell, the electrode group being comprised of a positive electrode and a negative electrode that are laminated together; wherein the anti-explosion mechanism includes a diaphragm, a connection plate welded to the diaphragm, and a connection lead welded to the connection plate; and the connection plate includes a thinner portion where a spot at which the connection lead is connected is formed as thin, and a thicker portion where the thinner portion is not formed, and a lower surface of the thinner portion is formed as coincident with a lower surface of the thicker portion, or as hollowed out from the lower surface of the thicker portion.

Hillock is prevented when aluminum wiring is used in order to reduce line resistance in a display unit. The aluminum wiring is formed into multi-layer structure and each layer contains an element which is not solidly solubilized with aluminum. The element are preferably rare earth metal such as Nd, high-melting point transition metals such as Ta and noble metals such as Pd. Intermetallic compounds of aluminum and the element are educed at an interface of the multi-layer wiring and it is prevented that grains of aluminum are enlarged to form hillock.

A semiconductor thin film is manufactured by scanning laser light or a substrate onto an arbitrary region of the semiconductor thin film and irradiating a laser thereon. The semiconductor thin film is formed by the substantially belt-shaped crystal being crystallized such that crystalline grains grow in the scanning direction, on the substrate, on XY coordinates where value x of beam size W (μm) of the laser light measured in substantially the same direction as the scanning direction is defined as X axis, and where value y of scanning velocity Vs (m/s) is defined as Y axis, the crystallization processing is performed within a region where all of the following conditions hold: condition 1: the beam size W is larger than wavelength of the laser beam, condition 2: the scanning velocity Vs is smaller than upper-limit of crystal growth speed, and condition 3: x×(1/y)

The present invention provides an image display device, in which a top electrode is selectively separated by laser ablation for each scan line. As the laser, a third harmonic wave of YAG laser with a wavelength of 355 nm is used. By setting film thickness of the interlayer insulator 15 to 100 nm and film thickness of a field insulator 14 to 140 nm, reflective spectrum has the minimum value near a wavelength of 355 nm, This laser beam is projected from a top electrode 13 toward a substrate 10. A part of the projected laser beam 20 is reflected by the top electrode 13, but most of the laser beam pass through a field insulator 14 and the interlayer insulator 15 and is reflected by a bottom electrode 11. As the result of interference of these two reflection waves, the minimum value appears in reflection spectrum. In this case, the laser beam is mostly absorbed near boundary surface between the top electrode 13 and the interlayer insulator 15. The top electrode 13 is processed by ablation (melting and evaporation), and the top electrode 13 is separated at this portion. By utilizing interference phenomenon in this manner, no damage is given to the interlayer insulator 13, the field insulator 14, and the bottom electrode 11, which serve as underlying layers, and the top electrode 13 can be selectively cut off.

An input data display device makes it easier to input properly correlated relative corrections for a number of parameters. Relative amounts by which each of a number of parameters is to be adjusted can be displayed on the screen in a manner which shows their ranges and possible correlation. The data are input when the operator touches spots which he selects on the display screen. The pressure of his finger causes data to be generated which represent those input positions. A calculation device calculates output-ready relative correction values for the various parameters based on these input position data. These values are transmitted to the connected device.

A small-sized, lightweight portable telephone has a microphone mounted on a rotatable arm that can be released into a use position using only one hand, which is also grasping the telephone. Even if an excessive load is applied to the microphone arm, which is rotatably supported relative to the telephone main member, damage is prevented by a spring-loaded detent mechanism. The microphone arm has built in it a core member formed of a shape-memory alloy and constituted by a flexible casing, so that deformation can occur without permanent damage to the arm.

A photoconductive device having a photoconductive layer which includes an amorphous semiconductor layer capable of charge multiplication in at least a part thereof is disclosed. The method of operating such a photoconductive device is also disclosed. By using the avalanche effect of the amorphous semiconductor layer, it is possible to realize a highly sensitive photoconductive device while maintaining low lag property.
