摘要:
A vibrating body for an acoustic transducer is provided, in which the high resonance frequency associated with inverse resonance can be outside the audible range and which can improve the acoustic characteristic of a speaker device. The vibrating body 1 for an acoustic transducer includes: a diaphragm 2 including a first vibrating part 2a and a second vibrating part 2b formed in proximity of the outer circumferential edge of the first vibrating part 2a; and an edge portion 3 formed in proximity of the outer circumferential edge of the diaphragm 2. In the vibrating body 1 for an acoustic transducer, first reinforcing portions 6a and 6b are formed so as to extend from the second vibrating part 2b to the edge portion 3 in a radial direction.

A cup shaped baked confectionary has light texture, uniform thickness and easy to release from the die. The cup shaped baked confectionary may be produced by mounting a dough of a cup shaped baked confectionary having desired contour shape on a top of a metallic three-dimensional baking die having desired shape of outer peripheral surface, in a condition extending horizontally with placing outer periphery thereof outside of the three dimensional baking die and heating the dough for softening the dough of the cup shaped baked confectionary to contact on the outer peripheral surface of the three-dimensional baking die and baking.

In a semiconductor integrated circuit mask layout verification method, a layout pattern division condition 108, according to which a plurality of specific layout patterns that need to have identical circuit characteristics are included, is input in a condition input step 109. In a data division step 103, input mask layout design data is divided into a plurality of layout pattern groups according to the layout pattern division condition. In a standard pattern selection step 105, a standard pattern serving as a standard in pattern matching is selected for each of the divided layout pattern groups. In a pattern matching step 106, for each of the layout pattern groups, layout patterns included in that layout pattern group are compared with the standard pattern.

A storage unit includes a cache memory, a cache controller which accesses the cache memory, one or more disk units, a data receiving unit, a merge interpolation determination unit, a data readout unit, a write data generation unit and a data write unit. The data receiving unit receives, from the cache controller, unit readout data that includes update records updated by the cache controller and is unit of data read from the cache memory. The merge interpolation determination unit determines whether the received unit readout data is merge interpolated. The data readout unit reads, from the disk unit, data corresponding to the unit readout data when the unit readout data is determined to be merge interpolated. The write data generation unit generates data to be written to the disk unit by merge interpolating the unit readout data. The data write unit writes, to the disk unit, the generated data.
摘要:
The present invention provides a light-emitting element mounting substrate which includes: a core metal provided with a reflective cup which reflects light emitted from a mounted light-emitting element in a prescribed direction, and an enamel layer having a thickness within a range of 50 μm to 200 μm, and provided on a surface of the core metal. The present invention also provides a light-emitting element module in which a light-emitting element is provided on this light-emitting element mounting substrate, and in which the light-emitting element is sealed with a transparent sealing resin.
