A different-material joint for welding is free from leakage even in extremely low-temperature environments and has high bonding properties in which an aluminum alloy has been disposed at one outermost end therefore and a stainless steel or steel has been disposed at the other outermost end thereof. The vacuum insulation panel includes a core provided with air circulation, a getter material which adsorbs moisture and gas from the core, an inner film bag which accommodates the core and the getter material, and an outer barrier bag which accommodates the inner film bag. The graphics controller is receives the frame. The identifier is then used to locate one of the plurality of records corresponding to the requestor. The supply voltage regulator derives a regulated internal power supply voltage ) from the external power source voltage, and this regulated internal power supply voltage ) is applied to one of the delay-contributing portions. These treatment profiles may, when centered on the eye, be suitable for treatment of standard refractive errors such as myopia, hyperopia, and cylindrical astigmatism.
