Abstract: A fiber optic light detector for determining the light intensity of a light emitted from a light source. The device includes a photocell, a light intensity display and two stationary pegs. The two pegs are spacedly positioned about the periphery of the photocell. When measuring light intensity, a fiber optic bundle illuminated by a light source is positioned to cover the photocell and be in contact with both of the two pegs. When the light source is positioned in this manner, complete coverage of the photocell is ensured regardless of the size of the fiber optic bundle. The light intensity display displays the digital value of the intensity determined by the photocell. The light detector is also adapted for connection and concurrent operation with a light source, i.e. a curing light.

Abstract: A magnetostrictive transducer including a plurality of magnetostrictive laminates each having a first end and a second end. The first and second ends of the laminates include openings. The laminates are arranged in a stacked configuration and bonded together by solder at the first and second ends. At the first and second ends the solder extends through the openings of the laminates forming a solder bar therein. The solder bars bond the laminates together with increased mechanical strength and also provide increased electrical contact between the laminates.

Abstract: An alternating current voltage regulator providing a stable RMS output voltage across a load. The voltage applied to the load being determined by controlling the firing angle of a triac, which is controlled by the pulse width of a timing signal generated in a timer circuit. The pulse width of the timing signal is controlled by an error signal. The error signal is based upon the actual triac output voltage as compared with a comparison signal. The voltage delivered to the load is compared with a RMS reference voltage to produce the comparison signal. The potential difference between the output voltage and the comparison signal is constantly monitored to produce the error signal. The error signal is thus constantly applied to vary the pulse width of the timing signal and thus vary the firing angle of the triac in accordance with the deviation of the actual output voltage from the stable RMS reference voltage. By constantly varying the firing angle of the triac with regards to deviations from the stable RMS reference voltage, the triac output is constantly adjusted to produce an output voltage substantially equal to the RMS reference voltage.

Abstract translation: 交流电压调节器，通过负载提供稳定的RMS输出电压。 通过控制由定时器电路中产生的定时信号的脉冲宽度来控制三端双向可控硅开关的触发角来确定施加到负载的电压。 定时信号的脉冲宽度由误差信号控制。 与比较信号相比，误差信号基于实际的双向可控硅输出电压。 将传送到负载的电压与RMS参考电压进行比较以产生比较信号。 不断地监视输出电压和比较信号之间的电位差，产生误差信号。 误差信号因此不断地被施加以改变定时信号的脉冲宽度，从而根据实际的输出电压与稳定的RMS参考电压的偏差来改变三端双向可控硅开关的触发角。 通过不断改变三端双向可控硅开关的触发角度，偏离稳定的RMS参考电压，三端双向可控硅开关量输出不断调节，以产生基本上等于RMS参考电压的输出电压。
