In an arbitration circuit in which a shared circuit such as a memory is used exclusively by one of a plurality of functional blocks at a time, an access reservation request is issued from one of the functional blocks, and the access request associated with the access reservation request is reserved. Thereafter, when an access request is issued from another functional block, it is determined which one of the access reservation request and the access request from these functional blocks takes precedence. For example, if the access request from the latter functional block has a low priority level, the access reservation request is selected and the circuit waits for an access request from the functional block which has issued this access reservation request. In this manner, it is possible to avoid cancellation of a once-accepted access request and waiting for a high-priority access request.

A discharge lamp electrode, a discharge lamp for which the electrode is used, and a method for producing a discharge lamp electrode with increased productivity are disclosed. With the disclosed discharge lamp electrode, deformations in its end portion are suppressed, so that the electrode life is extended. For the discharge lamp electrode tungsten wires are wound around an electrode rod in the same turning direction and form a first-layer coil and a second-layer coil A tungsten wire forming the second-layer coil is wound along a spiral valley between adjacent turns in the first-layer coil

A discharge lamp comprising an arc tube containing a pair of electrodes in a light-emitting portion and an outer tube that envelops the light-emitting portion and is at least partly fused to the arc tube, wherein the outer tube comprises silicon dioxide in the range from 90 to 99.88 wt. % and boron in the range from 0.12 wt. % or more. The discharge lamp can inhibit the arc tube from deforming when the outer tube and arc tube are fused to each other by adjusting a softening temperature of the outer tube to an appropriate temperature and can realize a high accuracy of luminous intensity distribution.

A lamp comprises a glass substrate and a shading film. The shading film is formed by applying a greensheet comprising an inorganic pigment and an inorganic matrix compound to a surface of the glass substrate and then, firing the greensheet. The formed shading film has a portion whose thickness is 90% or more of the maximum thickness of the shading film within the range of 0.5 mm from an edge of the shading film.

Lamp with shading film

A greensheet comprising an inorganic pigment and an inorganic matrix component is applied to a surface of a glass substrate and fired for fixing. The formed shading film has a portion whose thickness is 90% or more of the maximum thickness of the shading film within the range of 0.5 mm from an edge of the shading film. Thus, a shading film that has distinct end faces and has an excellent thickness uniformity can be formed with a good positional accuracy. Therefore, a lamp having a highly precise light distribution property can be obtained. In addition, a lamp having such a property can be obtained with a few steps and at a low cost.
