A semiconductor integrated circuit device includes a memory, /CE transition detector, address transition detector, /WE transition detector and controller. The controller includes a timeout circuit. The timeout circuit generates an internal circuit control signal with preset width to control access to the memory based on detection results of the above transition detectors. The operation of the memory is controlled by the timeout circuit at the read time. The operation of the memory is controlled by the timeout circuit when transition of the end of a /WE signal is detected by the /WE transition detector before a timing specified by the timeout circuit at the write time. Further, the operation of the memory is controlled in response to the transition of the /WE signal when the transition of the end of the /WE signal is detected by the /WE transition detector after passage of the above timing.

An optical fiber collimator array includes an optical fiber array block and a microlens array substrate. The optical fiber array block includes an angled surface and is configured to receive and retain a plurality of individual optical fibers, which carry optical signals. The microlens array substrate includes a plurality of microlenses integrated along a microlens surface and a sloped surface opposite the microlens surface. The microlens surface is coupled to the angled surface such that the optical signals from the individual optical fibers are each collimated by a different one of the integrated microlenses.

摘要:
A tilt angle sensor is disclosed that is capable of detecting whether a tilt angle of a reference plane exceeds a predetermined value by means of only one threshold value. Although only one threshold value is used, the tilt angle can be measured with respect to either a clockwise or a counterclockwise direction from the untilted state. A pair of differential electrodes electrically independent of each other are formed in a shape symmetric with respect to upper and lower sections of a printed circuit board. A common electrode plate is mounted opposed to the pair of differential electrodes with a predetermined gap therebetween. The pair of differential electrodes and the common electrode is stored in a closed space formed by the printed circuit board and an oil case. A dielectric liquid is filled into the closed space in such a way that the level of the liquid varies according to the tilt of the reference plane. An output signal corresponding to the difference in capacity between two capacitors formed by associated components is produced as a tilt detection output.
