摘要:
An internal combustion engine wherein a variable compression ratio mechanism which can change the mechanical compression ratio and a detection sensor for detecting the mechanical compression ratio are provided and wherein the mechanical compression ratio is controlled based on the mechanical compression ratio detected by the detection sensor. When a signal line of the detection sensor breaks, the mechanical compression ratio is lowered to the minimum mechanical compression ratio.

A highly accurate compound-eye unit is provided, which can assemble a compound-eye lens member to a lens holder with high positional accuracy even when using the compound-eye lens member that is unsatisfactory in dimensional accuracy of an external shape. A highly accurate compound-eye unit is provided, which can assemble a light shielding member having a plurality of apertures with high positional accuracy. A distance W2 between centers of apertures AP2, AP3 is smaller than a distance W1 between optical axes of convex lens units PL2, PL3, and hence, as illustrated in FIG. 13, when a lens member IM3 is made to approach a lens holder LH along an optical-axis direction, optical surfaces or external portions of peripheral surfaces of convex lens units PL2, PL3 abut on edge portions of the apertures AP2, AP3 at two points P, Q, and a flat surface FP abuts on an abutting portion CT. At this time, the flat surface FP abuts on the abutting portion CT, whereby the lens member IM3 and the lens holder LH are positioned in the optical-axis direction. On the other hand, the optical surfaces or the peripheral surfaces of the convex lens units PL2, PL3 abut on the apertures AP2, AP3, thereby attaining the positioning in an optical-axis orthogonal direction and the positioning around a Z-axis.

A high expansion ratio internal combustion engine includes: a variable compression ratio mechanism that varies a mechanical compression ratio of the internal combustion engine; and a variable valve train in which some valve(s) of a plurality of intake valves is phase-variable and the remaining valve(s) is phase-fixed, the variable valve train being configured such that a working angle of the phase-variable intake valve is larger than a working angle of the phase-fixed intake valve, wherein a valve-open timing of the phase-variable intake valve is retarded after a valve-open timing of the phase-fixed intake valve when the internal combustion engine is under low-load operating state.

A harness cover covering a wiring harness between a vehicle body and a door and having a cylindrical shape that is configured to accommodate the wiring harness on an inner circumferential side thereof may include a door-side grommet attached to one end thereof and capable of being connected to a grommet hole formed in the door, a body-side grommet attached to the other end thereof and capable of being connected to a grommet hole formed in vehicle body, and a bellows-shaped portion positioned between the body-side grommet and the door-side grommet. A set number of and a height of angled portions of the bellows-shaped portion are determined such that when the bellows-shaped portion is extended to a maximum at a time when the door is opened, a spread angle of each angled portion creates an acute angle.

A control signal output unit (62) outputs a rotational direction signal indicating a rotational direction of a motor (53) and a pulse width modulation control signal. A motor-driving unit (63) drives the motor (53) based on the pulse width modulation control signal and rotational direction signal inputted therein. A connection unit (64) electrically connects the control signal output unit (62) and the motor-driving unit (63) to transmit the pulse width modulation control signal and rotational direction signal outputted from the control signal output unit (62) to the motor-driving unit (63). The motor-driving unit (63) comprises a trouble-detecting unit (631). The trouble-detecting unit (631) successfully detects an occurrence of a trouble in the connection unit (64) by comparing the duty ratio in the inputted pulse width modulation control signal with the rotational direction in the inputted rotational direction signal.

Manufacturing condition data stored in a storage unit of a saving device is transmitted to a control device placed in an area different from an area where the saving device is placed. The transmitted manufacturing condition data is stored in a storage unit of the control device. A manufacturing device is controlled based on the manufacturing condition data stored in the storage unit to manufacture a product. Process data for the manufacturing condition data is transmitted and stored in the storage unit. After the step of manufacturing the product, the manufacturing condition data is erased from the storage unit. The process data is transmitted to the saving device. The transmitted process data is stored in the storage unit. After the process data is transmitted to the saving device, the process data is erased from the storage unit.
