An optical transceiver capable of narrowing an extra space for an external optical fiber is disclosed. The optical transceiver of an embodiment provides an optical receptacle with a port, to which the external optical fiber is to be inserted, headed for a direction in diagonal to the longitudinal axis of the optical transceiver. In another embodiment, the optical transceiver provides an optical receptacle capable of turning the port thereof.

When a light guide of a sleeve is inserted into a through-hole, a positioning rib is mounted in the holding recess and the sleeve is positioned in the housing. When a transmitting optical module is mounted in a housing space, a positioning protrusion of the sleeve enters a positioning recess of the transmitting optical module and contacts a stepped surface of the transmitting optical module. Thus, the transmitting optical module and a transmitting sleeve are positioned so as to face each other with high precision, and thereby the light transmission efficiency can be increased.

Disclosed is a device substrate wherein an insulating layer (60) having a terminal (24) formed on the surface thereof is formed over the entire surface of a glass substrate (20), excluding a display section, and therefore, the border (outer periphery) of the insulating layer (60) does not approach a region where an NCF (81) is provided, i.e., an area close to an LSI chip (40). This prevents the insulating layer (60) from being peeled off from the border thereof by the NCF (81), and thereby prevents the terminal (24) from breaking. Furthermore, the terminal (24) and a bump electrode (40a) are permanently pressure-bonded to each other by the elasticity of the insulating layer (60), and a stable electrical connection therebetween can be ensured.

A floating chuck mechanism provided at a workhead that is arranged at a processing apparatus for sandwiching a cylindrical-shaped workpiece by means of two center members along a rotational axis, the floating chuck mechanism causing the workpiece to rotate about the rotational axis and correcting an eccentricity between the rotational axis and a center of an outer diameter of the workpiece, includes a chuck body portion including plurality of clamp jaws for holding the workpiece from the outer peripheral side thereof, and a chuck base portion fixed to the workhead so as to rotate therewith, the chuck base portion including a fixed portion fixed to the workhead and a slide portion slidable along a slide surface perpendicular to the rotational axis. The chuck body portion is fixed to the slide portion and sliding along the slide surface so as to correct the eccentricity.
摘要:
A valve lifter, in which an amorphous hard carbon film is coated at least on the surface that slides against a cam, is characterized in that the surface of a base material (substrate) has an arithmetic mean roughness of Ra 0.01 to 0.03 micrometers, and the maximum length of the scratch on the base surface is made to be equal to or shorter than 250 micrometers.
摘要:
An air-fuel ratio sensor that outputs a sensor signal used for the feedback control of an air-fuel ratio is provided. It is determined whether an element crack is present by applying a reverse voltage to the air-fuel ratio sensor. The value of the sensor signal output from the air-fuel ratio sensor is corrected during a time period “A”. The time period “A” consists of a reverse-voltage application time period in which the reverse voltage is applied, and a return time period “T” after application of the reverse voltage ends. The return time period “T” is set based on sensor impedance correlated with the internal resistance of the air-fuel ratio sensor. The return time period “T” decreases as the sensor impedance decreases.
摘要:
An apparatus for selectively operating a plurality of computers connected to a common video monitor, includes a single data I/P device for inputting data and instructions to the plurality of computers, a main control circuit which is connected to the data I/P device, and a selection circuit for selectively providing the data and instructions from the data I/P device.The main control circuit outputs a computer selection signal to select one of the plurality of computers to which the I/P data and instructions are to be transmitted and a video selection signal to select the video output of the selected computer to allow display on the common video monitor.
摘要:
A sentence processing device used in a translation machine comprises sentence number input keys by which a block containing a plurality of sentences to be processed can be designated by inputting the sentence number assigned to the respective source sentences. All of the sentences included only in the designated block can be automatically consecutively processed.
摘要:
A process for producing a propylene resin formed article with a hard coat is disclosed, comprising forming an ultraviolet-curing acrylic resin coating film on the surface of a propylene resin film or sheet, subjecting the film or sheet with the coating film to thermoforming, and irradiating the coating film to ultraviolet rays to cure said ultraviolet-curing resin, wherein said propylene resin film or sheet is composed of at least a propylene resin surface layer containing substantially no nucleating agent on which surface is coated said acrylic resin film and a thermoplastic resin base layer containing a nucleating agent which is laminated on the other side of said propylene resin surface layer prior to the thermoforming. The hard coat on the propylene resin formed article has high gloss.
