Abstract: An optical frequency comb generator includes an oscillator (117) for oscillating modulating signals of a preset frequency, and an optical resonator (110) formed by an incident side reflecting mirror (112) and an outgoing side reflecting mirror (113), arranged parallel to each other. The optical resonator causes resonation in light incident via the incident side reflecting mirror (112). The optical frequency comb generator also includes an optical phase modulation unit (111) arranged between the incident side reflecting mirror (112) and the outgoing side reflecting mirror (113) for phase modulating the light, resonated by the optical resonator (110), by the modulating signals supplied from the oscillator (117), and for generating a plurality of sidebands centered about the frequency of the incident light at a frequency interval of the modulating signal. The outgoing side reflecting mirror (113) sets the transmittance from one frequency to another responsive to the light intensity of the generated sidebands.

Abstract: In a position closest to the mounting position of a microcomputer in a casing of a hybrid integrated circuit device on which is mounted the microcomputer and its peripheral circuit elements, an insertion hole is formed for a non-volatile memory which feeds data to the microcomputer. A socket for connecting the non-volatile memory is provided at the bottom of this insertion hole. Because of this configuration it is possible to connect the microcomputer and the non-volatile memory at an extremely short distance and the mounting efficiency of the integrated circuit device is increased. In addition, the non-volatile memory can detachably be mounted. Furthermore, the external shape of the insertion hole for the non-volatile memory is essentially the same as the external shape of the non-volatile memory so that when the non-volatile memory is inserted, the entire surface of this hybrid integrated circuit device is almost flat, providing excellent handling characteristics.

Abstract: In a connector structure for a hybrid integrated circuit, two hybrid integrated circuit boards each include a conductive layer having a predetermined pattern formed thereon and a plurality of circuit elements attached onto the conductive layer. The two integrated boards are separated from each other so that the conductive layers of the circuit boards oppose each other. The connector structure is provided with a pair of connecting pin support members which are fixed to the two hybrid integrated circuit boards, and on which a plurality of connecting pins connected to the conductive layers are attached. A connector housing has a fitting hole in which the connecting pin support members are fitted while overlapping each other.
