Abstract: A method for automatic control of a friction clutch (1) in a vehicle, which clutch is designed to be disengaged and engaged by a clutch actuator (3) under automatic control. An initial partially engaged clutch stroke position (Q1) and an initial clutch stroke position (P1) at which fluid pressure in the clutch actuator reaches a prescribed value are detected to obtain a difference (R1) between said two clutch stroke positions prior to initiation of automatic clutch control. The friction clutch wears as it is used. Therefore, both of the partially engaged clutch stroke position and the clutch stroke position attaining the prescribed fluid pressure value change while the automatic clutch engagement/disengagement control is being performed. However, the difference between these two clutch stroke positions does not change.

Abstract: 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.

Abstract: A vehicle equipped with a system (30) for automatically disengaging and engaging a friction clutch (13) coupling between an engine (11) and a transmission (16). The vehicle is also equipped with an automatic brake system (34) for automatically applying and releasing a brake to and from wheels (43). The automatic clutch disengagement/engagement system (30) performs high speed clutch engagement at the time of restarting the vehicle. The automatic brake system (34) releases the brake upon completion of the quick clutch engagement. The quick clutch engagement occurs in a clutch play range. The amount of quick clutch engagement is determined by depression of an accelerator pedal (10). Since the accelerator depression varies from when the vehicle is started on a flat road to when on an inclination, an optimum brake releasing is effected regardless of the road inclination if the timing of brake release is determined in this manner.

Abstract: An establishment for viewing an image can display an image which is projected on the image display device located outside the opening of the compartment of the establishment by the image producing device. The close scenery component is disposed between the compartment and the image display device such that the scenery component hides the edge of the image which is displayed on the image display device so as to allow parallax or perspective parallax to be produced between the image and the close scenery component. Hence, the image is given depth, high reality, and a sense of perspective, and the spectators have illusion as if they are seeing the real scenery from the opening.

Abstract: The present invention provides a prepreg having an excellent self adhesiveness to a honeycomb core, a low porosity when used as skin panels, an excellent surface smoothness due to a low surface porosity, and good tackiness and drapability. This invention also provides a honeycomb sandwich panel having a skin panel peel strength, an excellent impact resistance and an excellent hot water resistance, and a composition for a fiber reinforced composite material made from the prepreg and honeycomb sandwich panel. The fiber reinforced composite material made from the prepreg of the present invention can be used for airplanes, automobiles and other industrial applications, particularly as structural materials of airplanes, because of its excellent mechanical properties.

Abstract: In a vehicle with an automatically controlled clutch in which ON-OFF of the friction clutch is automatically controlled by a controller, clutch control during coasting (with the accelerator depression amount being 0%) is conducted according to a clutch ON-OFF map for coasting provided in the controller.Two different clutch ON-OFF maps for coasting are provided; one having a smaller hysteresis width, and the other having a larger hysteresis width. Clutch control during coasting is conducted by applying the map with a smaller hysteresis width when the brake pedal is stepped on or applying the map with a larger hysteresis width when the brake pedal is not stepped on. Thus, clutch ON-OFF hunting can be avoided, and smooth stopping can be conducted.

Abstract: The present invention relates to a floatable aircraft such as a parachute balloon. The parachute balloon is comprised an envelope which is able to be collapsed and stored during periods of nonuse. A parachute is attached to the envelope, enabling the parachute balloon to fall safely by the effect of the parachute in various circumstances including the usual descent or an emergency during a fall, such as when out of fuel.

Abstract: An image forming apparatus includes a photosensitive unit and a developing unit, at least one of which is arranged rotatable about a parallel support shaft. In a state that the both units are mounted on an apparatus main body, a developing roller gear (driven gear) of the developing unit is in mesh with a drive gear provided on the photosensitive unit. A drive force is transmitted from the drive gear to the developing roller gear. The developing roller gear and the drive gear are arranged such that a drive force acting on a pitch point has an extension line passing through a center of the parallel support shaft.

Abstract: Bioactive substances K93-0711 I-1 and I-2 having inhibitory action on IL-6 activity, are produced by culturing a microorganism belonging to the genus Streptomyces in a medium, whereby the bioactive substances K93-0711 I-1 and I-2 accumulate in the medium. These bioactive substances K93-0711 I-1 and I-2 are then isolated therefrom. The substances are effective for treatment of IL-6-involving diseases such as cancer cachexia, multiple myeloma and rheumatoid arthritis.

Abstract: A prepreg precursor including a carbon fiber woven fabric having applied to the fabric between about 0.5 to about 10 wt % of a stabilizer material for stabilizing the structural form of the fabric. Prepregs can then be produced using the woven fabric. Undesired settlement of matrix resin from the surface of the woven fabric is thus prevented. Hence, compared with a prepreg prepared using conventional woven fabric, a prepreg prepared by using the woven fabric of the invention can hold its tackiness for a long time and can be used to produce a fiber reinforced composite material excellent in smoothness without being devoid of surface resin.
