Abstract:
In an inner link rank 9 of a silent chain before pre-stress is applied, hole pitches of outer link plates 37 are shortened as compared to those of inner link plates 38 and 39 (P 17
Abstract:
A socket fixed to a heat sink holds a card-type LED module formed by integrating LED elements. The socket (6) includes: a frame structure for holding the LED module (1000) with its light source unit exposed through the frame opening; and a pressing member positioned around the opening for pressing the back surface of the LED module against the heat sink (2122). The socket may include a structure including a lower member (61) placed on a heat sink and an upper frame member (62) holding the LED module with its light source unit (1002) exposed through the frame opening. The upper member supported by the lower member via a hinge can open/close, and includes a pressing unit pressing the LED module set in the open state, against the lower member (61). The lower member (61) includes, in its main part, a lock unit (63) directly or indirectly lock the upper member (62) when the upper member is closed.
Abstract:
In a steering system having a variable gear transmission system and an electrical power steering system, respective compensation amounts for first and second electric motors are produced by a first mathematical model. The compensation amounts are added to command values (v1, v2) to generate final command signals (igref, ipref) to the respective electric motors. According to the above structure and operation, a mutual interference between two control systems can be suppressed.
Abstract:
An LED illumination includes an insertable and removable LED illumination source having a feeder terminal on one surface of a substrate on which an LED has been mounted; a thermal conductor member, which contacts with a back surface of the substrate on which the LED is not present; at least one connector to be connected to the feeder terminal; and a lighting drive circuit to be electrically connected to the LED illumination source by way of the connector, wherein, in the LED illumination source, a center of the substrate is shifted from a center of a light outgoing region of the substrate where the mounted LED is located.
Abstract:
An LED illumination source is disclosed. The illumination source includes a metal base substrate including a line pattern and an insulating layer including a composite material with an inorganic filler and a resin composition. LED bare chips are mounted on one surface of the metal base substrate An optical reflector with holes to surround the bare chips is provided on the surface of the metal base substrate on which the LED bare chips are mounted. Stress relaxing means is provided between the metal base substrate and the optical reflector.
