A drive control method includes detecting an angular displacement of a rotor driven by a pulse motor, calculating a difference between the detected angular displacement and a preset target value of the angular displacement, and calculating a drive pulse frequency of a drive pulse signal used to drive the pulse motor. The pulse motor is driven by the drive pulse signal having the drive pulse frequency to allow the rotor at a constant angular velocity.

A front grill structure includes a cover interposed between a front grill and a front bumper opening, which is formed in the upper portion of a front bumper to introduce engine cooling air, so as to cover the upper surface of the front bumper. A front bumper opening end and a bumper reinforcing flange are not visible through the front bumper opening because they are covered with the cover, and thereby the external appearance of the front grill structure can be improved. Further, since the bumper reinforcing flange is covered with the cover, it can be formed at any arbitrary height, and thereby the rigidity of the front bumper can be improved.

A starting apparatus for starting an engine only under constant conditions includes an electronically controlled clutch which is engaged or disengaged by an actuator in accordance with output signals from various detectors. The detectors sense a driving state, wherein a starter cut relay having normally-closed contacts is connected to an output terminal of an electronic control unit. One of the contacts of the starter cut relay is connected to one end of a relay coil for a starter relay. The other end of the relay coil is connected to a power source through a key switch. The other contact of the starter cut relay is connected to a non-grounded side contact of a neutral relay which is connected to the power source.

An image forming apparatus includes a molded frame 52 as a first structure fixed on a metal base plate 50 and a metal frame 54 as a second structure fixed on the metal base plate 50. The molded frame 52 is disposed in the metal frame 54 so that the molded frame 52 is not directly brought into contact with the metal frame 54. The mold frame 52 supports a plurality of parts which are related to an image forming portion and which are capable of being commonly used for operating the copying function, operating the printing function, and operating the facsimile-function. The metal frame 54 supports the other parts, such as a controlling device, reading device, an outer cover, and other parts. A rail member 60, which supports a sheet-supplying cassette so that the sheet-supplying cassette is freely moved in and out, is positioned with respect to the molded frame 52.
摘要:
An optical semiconductor module including a housing (54), an optical semiconductor assembly (56), a movable ferrule (84), and a sleeve (60). The housing (54) has a hole (80) into which a connector ferrule (76) is inserted. The optical semiconductor assembly (56) is accommodated in the housing (54). An optical fiber (74,82) having a first end (82a) and a second end (82b) is fixed in the movable ferrule (84). The movable ferrule (84) has a thin hole (84a) in which the second end (82b) of the optical fiber (82) is inserted and fixed. The first end (82a) of the optical fiber (82) is supported so as to be optically coupled to the optical semiconductor assembly (36). The sleeve (60) is accommodated in the hole (80) of the housing (54), so as to align the movable ferrule (84) and the connector ferrule (76) with each other. The movable ferrule (84) is biased so as to be pressed against the connector ferrule (76) in the sleeve (60). With this configuration, even if an optical connector is repeatedly mounted/demounted with respect to the optical semiconductor module, a high efficiency of optical coupling between the optical connector and the optical semiconductor assembly (56) can be stably maintained, thus providing an optical semiconductor module having a high reliability.
摘要:
Insert-parts are set onto a lower die (10), and resin tablets are supplied into pots (10a) for resin mold. A press mechanism A molds the insert-parts, a mold is opened, then the lower die (10) is slid to a first position, which is located side of a molding position. At the first position, an unloading mechanism (C) and a parts-loading mechanism (D) execute to clean parting faces of the mold, and to set resin tablets and insert-parts. The lower die (10) returns to the molding position for next molding. By sliding the lower die (10), works of taking out molded products, setting insert-parts, etc. can be easier, and the molding cycle time can be shortened.
