摘要： A voltage comparison unit compares a battery voltage with a predetermined threshold voltage, and outputs a comparison signal. A sequence circuit receives the comparison signal and a start-up signal instructing start-up of equipment mounted with a UVLO circuit, and executes a predetermined sequence when start-up is instructed by the start-up signal in a state the battery voltage is higher than the threshold voltage. A voltage control unit switches the threshold voltage based on the comparison signal and the start-up signal.

摘要： A case that houses a circuit component includes a frame along a peripheral edge of a circuit board, and a cover assembled to the frame so as to cover the circuit board, and connectors, facing an outer peripheral side of the frame are provided in the frame. In corresponding surfaces of the cover and each of the connectors, a first rib, a second rib, a first rib receiving groove, and a second rib receiving groove are formed that can regulate passage of a liquid in clearances between the connectors and the cover by fitting of protrusions and recesses. This prevents or limits a liquid outside the frame from entering the frame through the clearances between the connectors and the cover.

摘要： A laser diode drive system suited to a multitone image forming apparatus. For stopping laser emission from a laser diode the laser diode drive system superimposes a signal having a level corresponding to a maximum level of a video signal applied to the laser diode on a detection signal corresponding to emission intensity of the laser diode. A signal formed by the superimposition is used for negative feedback to a laser diode drive circuit.

摘要： An LED driving circuit drives a display backlight LED string including multiple LEDs connected in series. A power supply supplies a driving voltage from an output terminal thereof to a first end of the LED string. A detection resistor is arranged between a second end of the LED string and a fixed voltage terminal. The LED driving circuit receives a pulse modulation signal having a duty ratio that corresponds to the luminance. In the on period, in which the PDIM signal is the first level, the LED driving circuit controls the power supply such that the voltage drop across the detection resistor approaches a predetermined target value. In the off period, in which the PDIM signal is the second level, the LED driving circuit stops the control operation for the power supply.

摘要： A high-side transistor and a low-side transistor each has gate electrodes configured so as to allow signals to be input and output via a driving contact and a detection contact provided at different positions. When a control signal is at a first level and a signal output from the detection contact on the low-side transistor side is at a low level, the high-side driver applies a low-level signal to the driving contact on the high-side transistor side. When the control signal is at a second level and a signal output from the detection contact on the high-side transistor side is at a high level, the low-side driver applies a high-level signal to the driving contact on the low-side transistor side.

摘要： Fluid drainage slopes are formed at a lower frame part constituting a housing that is provided below circuit board housed inside housing. Drainage ports are also formed at a lowermost part of fluid drainage slope in lower frame part. Thus, fluid that forms in the housing flows down from circuit board and onto fluid drainage slopes to be guided downward from fluid drainage slope to reach drainage ports and be discharged to outside housing. It is thus possible to prevent or suppress the occurrence of short circuits in a circuit board caused by fluid generated and/or accumulated inside the housing.
摘要翻译： 流体排放斜坡形成在构成壳体的下框架部分处，壳体设置在容纳在壳体内部的电路板下方。 排水口也形成在下框架部分的流体排水斜坡的最下部。 因此，在壳体中形成的流体从电路板向下流动到流体排放斜面上，以从流体排放斜坡向下引导到排水口并被排放到外部壳体。 因此，可以防止或抑制由于在壳体内产生和/或积聚的流体引起的电路板中的短路的发生。
