An optical wavelength division multiplexing transmission network system having a star-topology network is disclosed, which comprises an arrayed-waveguide grating type multiplexing/demultiplexing circuit having N input ports and N output ports, and N transmitting/receiving apparatuses, each apparatus including a transmitter, receiver, demultiplexer, multiplexer, and N 2-input and 2-output optical path switching elements corresponding to N wavelengths, so as to cope with a damage to a transmitting or receiving portion corresponding to a specific wavelength. Each switching element is independently switched between first and second connective conditions. In the first connective condition, the output port corresponding to a specific wavelength of the demultiplexer is connected to the input port corresponding to the specific wavelength of the receiver, and the output port corresponding to a specific wavelength of the transmitter is connected to the input port corresponding to the specific wavelength of the multiplexer; and in the second connective condition, the output port corresponding to a specific wavelength of the transmitter is connected to the input port corresponding to the specific wavelength of the receiver, and the output port corresponding to a specific wavelength of the demultiplexer is connected to the input port corresponding to the specific wavelength of the multiplexer.
摘要:
A TTP comprising two substrates each provided with a transparent resistive-layer, and an insulating section formed on at least one of the transparent resistive-layers using an ultra violet curing resin or an electron beam curing resin. The glass transition temperature of the cured resin in the insulating section is not higher than 80° C., and the insulating section contains a methyl ethyl keton soluble component of not less than 5 weight % and not more than 80 weight %. Since the insulating section is cured at a low temperature, it may be formed on a plastic substrate whose heat-withstanding capability is low. The insulating section can be formed in any desired shape and it can be cured within a short curing time, which are quite advantageous properties for the production of TTPs in volume. The insulating section spreads only minimally during the curing operation, therefore the initial shape, if it is a fine pattern, can be well preserved. Since an acid, alkaline solution or organic solvent is not used for forming the insulating section in the present invention, TTPs thus manufactured are free from the safety problems on the production floor as well as the environmental hazards associated with the use of these chemicals. The same applies also to an electronic system that incorporates the TTP.

An improved semiconductor unit package is disclosed. This package is implemented by a semiconductor device having an electrode pad, a substrate having a terminal electrode, a bump electrode formed on the electrode pad, a conductive adhesion layer with flexibility, and an encapsulating layer formed by curing a composition the viscosity and thixotropy index of which are below 100 Pa.multidot.s and below 1.1, respectively. Such a composition essentially consists of (A) a resin binder that contains, for example, a polyepoxide, an acid anhydride, and a rheology modifier and (B) a filler. The rheology modifier is one capable of impeding interaction between a free acid contained in the acid anhydride and a polar group at the surface of the filler. An encapsulant with improved flowability is used, so that the encapsulant readily flows and spreads to fill a gap between the semiconductor device and the substrate with no air bubbles. This achieves semiconductor unit packages with high reliability and productivity.

An imaging apparatus include a lens, a first blade slidable between a covering position where the first blade covers the front side of the lens and a retract position where the first blade retracts from the front side of the lens, and a second blade pivotally supported by the first blade, the second blade moving along with the first blade between the covering position and the retract position in response to the slide motion of the first blade, the second blade rotating relative to the first blade in such a way that the second blade more largely overlaps with the first blade in the retract position than in the covering position.

A feedback path (307) is formed between an output (310c) of a fixed divider (305) and a control terminal (310b) of an inverting/noninverting unit (304). A connection device (306) is arranged on the feedback path (307). The feedback path (307) is connected/disconnected according to the level of the control signal M from outside, thereby switching the number of divisions. The delay time of the signal given to the input terminal (310a) of the inverting/noninverting unit (304) to pass through the feedback path (307) and return to the control terminal (310b) is set greater than the pulse width of the input clock signal. A small pulse input invalidating function is provided in the fixed divider (305). Alternatively, a small pulse output prohibiting function is provided in the inverting/noninverting unit (304). The fixed divider (305) divides the clock signal before division from the inverting/noninverting unit (304) according to the leading edge of the clock pulse of the normal pulse width in the signal (a change point corresponding to the leading edge of the input clock signal).

A mixer circuit for frequency conversion operates with low power supply voltage lower than 1 V. The circuit comprises a first pair of N-channel MOS transistors and a second pair of N-channel MOS transistors each receiving differential local frequency signal, and a third pair of P-channel MOS transistors receiving differential radio frequency signal. Each pair of transistors is coupled in series with a parallel resonance circuit which operates as a constant current source. A drain of each transistor of the third pair of transistors is connected to a junction of a first pair and a second pair of transistors and a parallel resonance circuit. An output intermediate frequency signal, which differs between the local frequency and the radio frequency, is obtained at the junction of drains of the first and the second pair of transistors and load resistors. No series connected transistor is inserted between a power source and a ground, and each pair of transistors is inserted between the power source and the ground essentially in parallel with one another.
