    摘要: An object of the invention is to achieve a small and thin irregular pattern reader comprising: a prism possessing a detection surface on which a subject to be detected having an irregular pattern is put and an incident plane having a first angle of inclination to the detection surface and emitting a light reflected on the detection surface corresponding to an incident light incident upon the incident plane; a first optical system possessing a light source and causing a light from the light source to be incident upon the incident plane of the prism with its optical axis substantially in parallel to the detection surface; and a second optical system for transmitting the emission light emitted from the prism to an image pick-up device.

    摘要: A sense amplifier has a pair of internal nodes that are precharged to a power-supply level. A first pair of n-channel transistors supplies current to the internal nodes responsive to a pair of data signals, both of which are initially high. When one of the data signals begins falling toward the low level, the corresponding n-channel transistor immediately reduces the current supplied to one of the internal nodes. A second pair of n-channel transistors, cross-coupled to the internal nodes, amplifies the resulting potential difference between the internal nodes, thereby pulling down the potential of one of the internal nodes. An output signal is generated from one or both of the internal nodes. The output signal is obtained quickly, because amplification begins without delay.

    摘要: Circumferential grooves 6c and 6d are respectively formed in the outer peripheral surface 6a and inner peripheral surface 6b of a floating ring 6, and the circumferential groove 6d is used to form a lubricant feed portion 8 in a clearance 7 between the outer peripheral surface 1a of an inner race 1 and itself, while the circumferential groove 6c is used to form another lubricant feed portion 8 in another clearance 7 between the inner peripheral surface 5b of a cage 5 and itself, thereby being able to improve lubricating conditions between the two respective partner portions.
