A vehicle headlamp comprises: a discharge bulb; and a reflector having a reflecting surface including a plurality of reflecting surface elements to reflect the output light of the discharge bulb forwardly, wherein an sub light distribution pattern having an oblique cut line and a horizontal cut light is formed by controlling light reflected from the reflecting surface elements. Of the plurality of reflecting surface elements, oblique cut line forming reflecting surface elements, and horizontal cut line forming reflecting surface elements extend above the lines of intersection between the reflecting surface and an inclined surface which passes through the optical axis of the reflector and has an angle of elevation of 15.degree..

An automobile headlamp with a reflecting surface comprising a plurality of light distribution steps arranged on the surface. Out of the plurality of light distribution steps 12a constituting the reflecting surface 12, the light distribution steps 12aA, 12aB positioned at upper left and upper right corners with respect to an optical axis Ax of a reflector 10 are formed so that luminous fluxes of reflected light from upper areas A1, B1 thereof and luminous fluxes of reflected light from lower areas A2, B2 thereof can emit downward with broken lines interposed therebetween. As a result of this construction, even if headlamp parts forming accuracy requirements are not adequately met, undesired upward emitting of the luminous fluxes of reflected light from the upper areas A1, B1 is prevented. Further, by forming the upper areas A1, B1 and the lower areas A2, B2 of vertically long single light distribution steps 12aA, 12aB, respectively, not only division of the reflecting surface 12 into small segments can be minimized, but also steps between the upper areas A1, B1 and the lower areas A2, B2 are eliminated, so that the likelihood that upward scattered light will be generated is excluded.

A printing apparatus prints by discharging inks from respective nozzle arrays, the printhead having a plurality of nozzle arrays including at least a first nozzle array, a second nozzle array, and a third nozzle array, and the first nozzle array and the second nozzle array being arrayed to be shifted in a nozzle arrayed direction. The printing apparatus controls the first and second nozzle arrays to discharge inks to form a plurality of first patterns. The printing apparatus controls the third nozzle array to discharge inks to form second patterns while changing a shift amount in a direction which intersects with the nozzle arrayed direction with respect to the plurality of first patterns. The printing apparatus calculates an adjustment value required to adjust relative printing positions between the first nozzle array and the third nozzle array in the intersecting direction using the first patterns and the second patterns.

A vehicle lamp includes a semiconductor light emitting device arranged to face toward a front of the vehicle lamp, a first optical member disposed in front of the semiconductor light emitting device, and a second optical member disposed in front of the first optical member. The first optical member comprises a front surface and a back surface. The front surface is configured to internally reflect light from the semiconductor light emitting device toward the back surface. The back surface is configured to internally reflect the light reflected by the front surface back toward the front surface such that the light exits the first optical member from the front surface. The second optical member is disposed directly in front of the front surface of the first optical member and diffuses the light from the first optical member to form a light distribution pattern.
摘要:
An inkjet printing apparatus and an inkjet printing method are provided which can correct, with high precision, print position deviations among a plurality of printing element arrays in each of a plurality of print modes that use different groups of printing elements in each printing element array. The adjustment values for the print position deviations between the first and second printing element arrays are differentiated between the high-speed mode and the high-quality mode. In the high-speed mode, all printing elements in the first and second printing element arrays are used. In the high-quality mode, a part of the printing elements in each of the first and second printing element arrays are used. Based on these adjustment values, the ink ejection timings of the first and second printing element arrays are adjusted.
