    摘要: A group-IV semiconductor substrate has an inclined front surface, the inclination being toward a direction differing from the crystal lattice direction. The substrate is cleansed by heating in the presence of a gas including a compound of the group-IV substrate element. A source gas of a group-III element is then supplied, forming an atomic film of the group-III element on the substrate surface. Starting at the same time, or shortly afterward, a source gas of a group-V element is supplied, and a III-V compound semiconductor hetero-epitaxial layer is grown. Chemical bonding of the group-III element to the group-IV substrate surface produces a crystal alignment of the hetero-epitaxial layer that leads to improved conversion efficiency when the semiconductor substrate is used in the fabrication of solar cells with compound semiconductor base and emitter layers.

    摘要: An ignition timing control system for an internal combustion engine, including a vacuum actuator connected to turn a point base about the axis of the rotary cam which operates the breaker points to advance or retard the ignition timing. The vacuum actuator employs two vacuum chambers, one used primarily to advance the timing, the other used to retard the timing. Each chamber communicates with an engine intake passage downstream from a throttle valve. Electromagnetic selector valves, one associated with each vacuum chamber, serve to connect each vacuum chamber to the engine intake passage, or alternatively to vent each vacuum chamber to atmosphere. These selector valves may be energized by a temperature switch, a velocity switch or a cruise switch. A check valve maintains vacuum intensity in the spark advance chamber when the vacuum intensity at the engine intake passage is lowered by virtue of the opening of the throttle valve.

    摘要: A reflection sensor includes the following elements. A light emitting unit emits light to an area of an image forming apparatus where first detection images of plural colors used for detecting amounts of their misregistration are formed. A first light restricting member/configuration restricts light emitted from the light emitting unit. A light receiver is disposed in an optical path of regular reflection light, and receives reflected light and outputs a signal representing an amount of received light. A second light restricting member/configuration is disposed in the optical path of the regular reflection light and restricts light to be received by the light receiver. The value obtained by dividing a diameter of the first light restricting member/configuration by that of the second light restricting member/configuration ranges from substantially 0.5 to 1.9, and the diameters of the first and second light restricting members/configurations are each 1.5 mm or smaller.
