摘要： A support bracket for mounting an engine component to a surface, such as to a cylinder head or engine block. In an embodiment, the support bracket includes a base member, a shelf member and a spacer. The base member has a back portion with a shape that defines a forwardly facing channel. The spacer is shaped to be matably received in the channel, optimizing load distribution between the spacer and the base member. A bolt hole extends through the spacer and is aligned with a bolt hole in the base member. The shelf member is welded to the base member to permanently capture the spacer in the channel. Welding the spacer is unnecessary. The spacer may be made of powdered metal. The spacer provides a free length portion of the capscrew that mounts the bracket against a surface, the free length accommodating longitudinal stress on the capscrew.

摘要： Integrated circuit amplifier (10) implements unity voltage gain and its current gain is determined by the ratio of integrated circuit resistors (R1, R2). Amplifier input stage (Q1, Q2, Q4-Q7) has a pair of transistors (Q4, Q5) connected as a differential amplifier. An output transistor (Q13) connected to the collector of one (Q4) of the differential transistors amplifies the differential signal from the input stage and provides an output signal (at terminal 22). Current mirror circuitry (Q12, Q9) develops a current mirror signal (at 24) corresponding to current drawn through the output transistor (Q13). A load balancing circuit (Q8, Q3, R8) includes a transistor (Q3) having an input terminal directly connected to and loading the collector of another one (Q5) of the differential transistors. This configuration results in equal impedance and current loading for each of the collectors of the differential transistors (Q4, Q5). This minimizes any offset variation for the differential signal at the collector of one of the transistors (Q4) as a function of the conduction of the output stage tansistor (Q13). This results in a more accurate true differential amplification by the differential input stage resulting in the amplifier current gain being a more direct function of just the ratio of the integrated circuit resistors.

摘要： Load driver circuit (10) has first and second comparators (Cphd 1, C.sub.2) which receive a load current signal (V.sub.s) indicative of current flowing through a load (11). The comparators provide, as output signals, set on and set off signals (at 21, 23) in response to comparing the load current signal (V.sub.s) with first and second thresholds (T.sub.1, T.sub.2). Driver circuitry (27, 43, 12) receives the set on and set off signals and provides a current control signal (at 18) for controlling load current. Preferably, disabling circuitry (30-34) disables the comparators (C.sub.1, C.sub.2) after and in response to the comparators providing their respective output signals (at 21, 23). Also, preferably enabling circuitry (40-42) enables the comparators (C.sub.1, C.sub.2) in response to comparing a sensed voltage (at 17), indicative of voltage at an output terminal of a switching device (12) that controls load current, with respect to a predetermined voltage (2.5 volts). The selective enabling/disabling of the Comparators (C.sub.1 , C.sub.2) results in minimizing the possible effect of noise with respect to controlling load current since undesired false or repetitive outputs of the comparators are minimized.

摘要： A voltage supply circuit provides a desired regulated voltage at an output utilizing a PNP and an NPN current mirror arranged to oppose one another. The NPN current mirror includes a pair of transistors operated at different current densities which produce a delta V.sub.BE voltage that is used to produce a reference current. The reference current is used to derive the regulated voltage which is a function of two independent resistor ratios.

摘要： An electronic energization circuit is provided to illuminate a gas discharge lamp that includes a transformer with a substantially rectangular hysteresis loop. A secondary winding on the transformer is connected to energize the lamp and at least one primary winding is provided on the transformer. Input voltage terminals may be DC terminals to supply an input voltage to the circuit. At least one semiconductor, such as a transistor, is connected to the input terminals and to the at least one primary winding, and a control means is provided for the semiconductor for unequal on and off conduction periods of the semiconductor. These unequal periods provide the conditions which eliminate the striations (bubbles) or dark spots in the gas plasma of the lamp, usually associated with high frequency energization. When two semiconductors are used in a circuit, they conduct alternately in a type of square wave oscillator circuit and the duty cycle of the two transistors is different so that the striations in the illumination of the lamp are eliminated. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

摘要： A slew rate limited load driver is disclosed with a transistor switch (123) driving a load (125). The transistor switch (123) is controlled by a current from a current amplifier (107) and a current sink (111). The current amplifier (107) is driven from the combination of a source of compensating current (120) and a turn on current source (115). As a command signal (103) transitions, the source of compensating current (120) adds a transitional compensating current to the current derived from the turn on current source (115) and is amplified by the current amplifier (107). The output of the current amplifier (107) is combined with the output of the turn off current sink (111), to control the voltage slew rate to the load (101).

摘要： A power driver including a switch (17) that connects between a power input terminal (12) and a power output terminal (13). A current sense unit (22) provides an over current sense signal if an over current condition should exist with respect to the switch (17). A reference signal unit (23) utilizes a control signal as introduced at a control signal input (11) to provide a threshold current level signal. A comparator (21) compares the latter two signals and provides an enabling signal to a second switch (19) to disable the switch (17) upon detecting an over current condition. The comparator (21) is enabled by the control signal.
