A semiconductor integrated circuit receiving a plurality of input signals each exhibiting a signal-level change during a predetermined time span includes a timing-detection circuit which detects timing of said signal-level change of said input signals, and detects which input signal is furthest behind in terms of a signal-level-change timing among said plurality of input signals within said predetermined time span. The semiconductor integrated circuit further includes first delay-adjustment circuits which delay said plurality of input signals, respectively, in response to an output signal from the timing-detection circuit to generate delayed input signals such that signal-level-change timings of said delayed input signals are aligned to said signal-level-change timing of said furthest behind input signal, and latch circuits each latching a respective one of said delayed input signals at the same timing.

A polarizing beam-splitter comprises an optically isotropics crystalline substrate and a birefringent material layer made of an oriented polydiacetylene film formed on the optically isotropic crystalline substrate. A periodic grating photo-mask is formed in the birefringent material layer by an area that is changed into a different color phase when an ultra violet light is irradiated in a predetermined pattern on the birefringent material layer and by an area in which the color remains unchanged. The periodic grating photo-mask has a diffraction efficiency for the orientation of the oriented polydiacetylene film in the area that is changed into a different color phase which is lower than that in the area in which the color is unchanged.

A path control method includes a procedure for developing a path control message including regional information in transmission on the network. The regional information designates a path and/or a path length for transmitting the path control message. The path control message includes a regional property for instructing each node as to how to process the regional information either in a strict manner or in a flexible manner. With reference to the regional information and/or the regional property, each node is capable of selecting a destination node to which the path control message is to be transmitted, stopping the further transmission of the path control message, or discarding the path control message.

Described herein is a method for simulating indoor illuminance which includes preparing an intrinsic optical property function of a bidirectional transmittance function and a bidirectional reflectivity function based on values actually measured for each plate-shaped optical member; for a skylight constructed by combining a plurality of those optical members, creating an optical physical model based on the intrinsic optical property function and the construction mode of each optical member constituting the skylight; calculating the skylight light distribution data for daylight, which is introduced through the skylight, by using the optical physical model; and simulating the indoor illuminance, which would be provided by actually installing the skylight, on the basis of the light distribution data. The simulation is performed on a computer system which has stored the intrinsic optical property function of each optical member in a database.

An electrode for a lithium-ion secondary battery includes a collector of copper or the like, an electrode material layer being form on one surface and both surfaces of the collector and including an active material and a binder, and a binder-rich layer being formed in a dot shape or a stripe shape with a predetermined interval in the interface between the collector and the electrode material layer and having a binder concentration higher than that of the electrode material layer. Accordingly, a concentration gradient of the binder is provided to the surface of the collector. By arranging the binder-rich layer at a predetermined interval, it is possible to improve the adhesiveness between the collector and the electrode material layer due to an anchor effect and to guarantee conductivity between the collector and the electrode material layer.
