A vehicle light can be configured to have a depth that is remarkably small. The vehicle light can include a first reflector that is an ellipse group reflector with a major/optical axis thereof inclined, a second reflector that is a parabolic group reflector located below the first reflector so that the second reflector can receive light reflected from the first reflector, and a light source located in the vicinity of the first focus of the first reflector.

摘要:
A head lamp for a vehicle wherein an actuator is made to be able to be moved to a leveling actuation range corresponding to output from a vehicle body sensor and to a beam change position B out of a leveling actuation range when a beam changing switch is set to a drive beam position, and if the actuator is moved to the beam change position B at least a part covering a lower half of a discharge lamp of the hood is moved back to switch it from a passing beam state to a drive beam state. The actuator for leveling actuation indispensable to be provided for the head lamp for a vehicle having the discharge lamp as a light source, makes it possible also to switch between the passing beam state and drive beam state, thereby dissolving problems of large size and high cost of the head lamp.
摘要:
In a process for producing a polycarbonate by subjecting a dihydroxy compound and a diester of carbonic acid to melt polycondensation through transesterification, after a polycarbonate prepolymer is prepared in the first-stage reaction, polycondensation is conducted as the second-stage reaction at a residence time in the range of from 15 to less than 60 min or through the use of at least one paddle-type self-cleaning twin-screw extruder.This process enables a colorless, transparent polycarbonate having a high molecular weight to be produced at a high efficiency on an industrial scale.
摘要:
A novel control device for switches fitted onto an automobile steering wheel including a rotary sensor and a rotation discriminating circuit to detect the turning angle of the steering wheel when changing the running direction of the automobile to the right or left and prevent the load of the switch from being actuated even when another switch fitted onto the center of the steering wheel is maloperated while operating a turn signal lamp.This control device makes the turning operation of the steering wheel easier and at the same time, it can contribute to the safe driving of the automobiles.Furthermore, the device can be constructed with simple parts and mounted readily on the existing automobiles.
摘要:
Disclosed are titanium dioxide-containing composite particles which can maintain whiteness of natural titanium dioxide even after calcination step, and can provide titanium dioxide-containing composite particles having excellent weather resistance. In each of the composite particles, at least one oxide layer containing silicon oxide and zirconium oxide is provided as coating components of titanium dioxide. That is, provided are composite particles including a base that contains titanium dioxide and at least one oxide layer that contains silicon oxide and zirconium oxide provided on the base, and a method of producing the composite particles.
