A microphone unit converts voice into an electric signal based on the vibration of a diaphragm contained in an MEMS chip. The microphone unit includes a substrate on which the diaphragm is mounted (the MEMS chip is mounted); a cover member, having sound holes, that is disposed above the substrate so that the diaphragm is contained within the inner space formed between the cover member and the substrate; and a holding member that holds only the substrate or both of the substrate and the cover member.

Microphone unit and voice input device using same

An optical connector system comprises at least one shield case () provided through a panel () at a through-hole of the panel, and at least one pair of housings (and) provided in the shield case, each housing receiving at least one plug () and having at least one sleeve () for aligning and holding top end of the plug. The shield case comprises at least one insertion hole () in which the plug is inserted, a partition plate () made of a conductive material and provided between the pair of housings, and a flange portion () made of a conductive material and grounded to the ground of the panel. The partition plate and flange portion are provided such that leakage and entrance of electromagnetic waves from the through-hole of the panel are minimized.

Optical connector system

A tandem type optical connector () includes at least one tandem type adaptor () having opposite plug engaging cavities () each receiving an optical cable connector (') and a shield cover () provided over the adaptor () and having at least one panel fixing member () to attach the optical connector () to a panel at an angle other than right angles with respect to the panel ().

Tandem type optical connector

An adapter or connection comprises a plurality of adapter or connector sections ( ) having plugging cavities ( ) to which optical cable plugs ( ) are detachably plugged. The plugging cavities ( ) are arranged in a plane of a panel ( ) at an acute angle to the plane thereby preventing light from entering the operator's eye upon plugging.

Optical cable adapter or connector

An optical adapter for receiving a plurality of detachable plugs ( ) to which optical cables are connected. The optical adapter comprises a conductive housing ( ) having a plurality of conductive cavities ( ) for receiving the detachable plugs ( ) and a plurality of conductive partition walls ( ) provided between the plugging cavities ( ). The conductive housing ( ) is attached to a conductive panel ( ) to electrically connect the optical adapter to the conductive panel ( ).

Optical fiber with lens and method of manufacturing the same

In an optical contact unit and an optical connector using the optical contact unit, the optical contact and other components are integrated into a single unit which is collectively mounted and removed to and from the optical contact holding member so that the mounting and the removing operations is facilitated. The optical contact unit comprises an optical fiber with an end portion, a ferrule fitted onto the end portion of the optical fiber, a sleeve containing and supporting the ferrule so that the ferrule is movable in an axial direction thereof, a biasing member contained in the sleeve for biasing the ferrule to make the ferrule project from the sleeve in the axial direction, and a stopper for limiting the movement of the ferrule which is forced by the biasing member to move in the axial direction with respect to the sleeve. The optical connector comprises the optical contact unit of the above-described structure, an optical contact holding member having a receiving hole for receiving the optical contact unit, and a clip fixed in the receiving hole for locking the optical contact unit to the optical contact holding member.

Optical contact unit and optical connector using the optical contact unit

An optical connector comprises an optical connection adapter and an optical plug. The optical connection adapter includes a sleeve to be attached to a first circuit board. The optical plug includes an optical contact to be inserted into and removed from the sleeve, and a contact holding member to be attached to a second circuit board. A variation of the optical connector comprises an optical connection adapter and an optical socket. The optical connection adapter comprises a pipe, an optical fiber arranged in the pipe, an optical connector connected to opposite ends of the optical fiber, and a contact holding member which is inserted into the pipe to be movable along the cylindrical axis and which is for holding the optical contact. The optical socket comprises a socket housing which has an insertion hole for removably receiving the optical contact and which is to be attached to the second circuit board, and a mating optical contact which is fixed to the socket housing and which is to be brought in to contact with the optical contact through the insertion hole.
