A vehicular lamp includes a light source unit that is attached to one of a lamp body and a reflector. The light source unit includes a semiconductor light emitting element that is a light source; a plurality of conductive members formed into a predetermined three-dimensional shape by press working a conductive metal material; and a housing that is formed of an insulating material. The plurality of conductive members each include: an element mounting portion to which the semiconductor light emitting element is mounted, a heat dissipating portion that dissipates heat generated when the semiconductor light emitting element emits light, and a connecting portion to which a connector that supplies power to the semiconductor light emitting element is connected. The housing holds the plurality of conductive members in a spaced apart state.

A storage body with improved decorativeness and an improved degree of freedom in its function and in its design comprises a main body, a cover body, and a locking mechanism. The main body has an opening portion. The cover body is supported by the main body in such a manner that the opening portion can be opened and closed, and has a pair of engaging holes. The locking mechanism engages the cover body with the main body at a position where the opening portion is closed. The locking mechanism is composed of a pair of rods, an urging member, an operating member, and a linking member. The rods, the urging member, and the linking member are provided on a side of the main body, not on the side of the cover body.

To provide an excimer laser device and method in which the frequency of full gas exchange within the laser chamber is reduced, and more preferably full gas exchange is made unnecessary. The gas supply device and gas exhaust device are controlled so that the laser gas in the laser chamber is partially exchanged in a gas exchange quantity that maintains the quantity of impurities in the laser chamber at or below a fixed level. Also, the gas exchange quantity is obtained using the total quantity of output light energy reduction A, the total gas pressure in the laser chamber P, and output light energy reduction quantity per unit time k, for the case where partial gas exchange is repeated infinitely in the laser chamber.

The amount of pre-ionization by the pre-ionization electrode provided on the gas outflow side of the main discharge space, out of at least one pair of pre-ionization electrodes, is adjusted so as to attain the desired beam profile. As a result, the pre-ionization intensity of the laser gas remaining on the gas outflow side of the main discharge space is made lower than the pre-ionization intensity of the laser gas flowing into the main discharge space. In other words, the intensity of the laser light on the gas outflow side of the main discharge space is made weaker than the intensity of the laser light in the center of the main discharge space. Accordingly, the location of the maximum light intensity of the beam profile does not deviate from the center of the discharge width. Also, since the pre-ionization electrodes are provided on both the gas inflow side and the gas outflow side of the main discharge space, the pre-ionization intensity of the laser gas on the gas inflow side of the main discharge space is never stronger than the pre-ionization intensity of the laser gas present at the center of the main discharge space.

A motor controller is provided with a first PWM circuit that repeatedly outputs an on-signal at a first carrier frequency, a second PWM circuit that repeatedly outputs an on-signal at a second carrier frequency that is lower than the first carrier frequency, an AND circuit that receives both the on-signal outputted from the first PWM circuit and the on-signal outputted from the second PWM circuit and outputs a third on-signal which is a logical product of the received on-signals, and a voltage apply circuit that applies a voltage to the motor intermittently in synchronization with the third on-signal outputted from the AND circuit. At least one of the first carrier frequency and the second carrier frequency is equal to or lower than 1 kHz or equal to or higher than 3 kHz. As a result, generation of an unpleasant noise by a motor controller using two PWM circuits may be suppressed.
