Abstract: A vehicle lamp includes an optical means whereof the direction of irradiation is change by rotation, a motor, an output shaft for driving the optical means, and a rotation transmitting mechanism for transmitting rotation from the motor to the output shaft. The motor, the output shaft, and the rotation transmitting mechanism are accommodated in the case body, and a revolving shaft of the motor is supported by the case body.

Abstract: A vehicle lamp includes a drive portion having a drive source, and a lamp body that has a light source and that is supported by a rotary shaft operable to be rotated by the drive portion. A rotary contact is provided around the rotary shaft and rotates together with the lamp body. A fixed contact is provided for the drive portion. The rotary contact and the light source are electrically connected through a power supply cord and electric power is supplied to the fixed contact.

Abstract: A vehicle lamp including an optical means having a light source to be rotated by the driving unit having a driving source. The driving unit is provided with a rotational position detecting means including a base member and a rotating body being rotatable with respect to the base member for supplying signals corresponding to the rotational position of the rotating body with respect to the base member of the rotating body, and the optical means and rotating body of the rotational position detecting means are connected by clutch means.

Abstract: The lighting device for a vehicle includes running direction detect means 3 for detecting the vehicle running direction or the vehicle steering angle and vehicle speed detect means 4 for detecting the vehicle speed. An illumination control means 5 specifies the turn-on and turn-off of a plurality of lamps in accordance with detect signals output from the means 3 and 4, thereby changing the combinations of the illumination ranges of the lamps.

Abstract: An infrared-ray radiating lamp which is prevented from being mistaken for a tail lamp or a stop lamp by ensuring that not only infrared rays but also visible rays are emanated from a front lens simultaneously. The lamp includes a lighting chamber defined by a lamp body and a front lens, a reflector disposed in the lighting chamber, and infrared-ray radiation means and visible-ray radiation means disposed in front of the reflector in the lighting chamber. The infrared rays radiated from the infrared-ray radiation means and the visible rays radiated from the visible-ray radiation means are emanated from the front lens simultaneously when the lamp is lit. Thus, the rays distributed by the lamp include both red infrared rays and white visible rays, and therefore a red color is not particularly noticeable. Thus, the infrared-ray radiating lamp when lit is not mistaken for a tail lamp or a stop lamp.

Abstract: An apparatus for leveling a vehicle lamp such that an opening of the pivot receiving body is formed in a non-circular shape; the cross sectional shape of the pivot body in a direction perpendicular to the axis of the pivot body is formed so that the pivot body can be inserted into the opening of the pivot receiving body in at least one direction; and the cross sectional shape of the pivot body cannot be inserted into the opening of the pivot receiving body in at least the other direction; and the pivot body is prevented from slipping off the pivot receiving body by turning the pivot body by a predetermined angle around the axis of the pivot body after the pivot body is inserted into the pivot receiving body.

Abstract: A vehicle headlamp has a reflector coupled to a lamp housing via a pivotal connection and two aiming mechanisms for tilting the reflector relative to the lamp housing about horizontal and vertical axes intersecting at the pivotal connection. One such aiming mechanism comprises an aiming screw rotatably mounted to the lamp housing, a socket member affixed to the back of the reflector, and a ball with a tapped hole extending therethrough to fit over the aiming screw. The socket member has a hollow extending therethrough for receiving the aiming screw with clearance. Part of the hollow in the socket member is formed into a socket for rotatably receiving the ball on the aiming screw. A lockpin on the ball is engaged in a slot in the socket member thereby locking the ball against rotation relative to the socket member about the axis of the hole therein.

Abstract: A spring steel having a good durability and a good sag-resistance consisting essentially of by weight 0.35-0.55% carbon, 1.80-3.00% silicon, 0.50-1.50% manganese, 0.50-3.00% nickel, 0.10-1.50% chromium, 0.01-0.05% aluminum and 0.010-0.025% nitrogen, the remainder being iron and inevitable impurities.The spring steel has been completed for the purpose of obtaining a spring steel having a high toughness in a high hardness of not less than HRC 55 and having a good sag-resistance, in particular examining the contents of nickel, chromium and nitrogen in addition to the carbon content.

Abstract: A portable electric power source for movable welding equipment used for constructing storage tanks and the like comprises a platform; an engine mounted on the platform; an AC electric generator mounted on the platform and driven by the engine; a welding machine, mounted on the platform, including electric current inverter and transformer means by which AC electric current from the generator is converted to DC welding current; and current transmission means for conveying the welding current from the welding machine to the welding head of the associated welding equipment. The welding equipment and the power source are mounted on carriages which are coupled together so as to move in unison as the welding operation progresses.
