Title: A circuit of multiple-voltages manipulation of tree-type network
Inventor: YANG TAY-HER
IPC: H03H11/00
Filed: 1991-12-26
Granted: 1993-01-21
Abstract: An improvement of tree-type network multiple-voltages manipulation circuit combining linear or clipper solid-state switch devices for multiple-voltages switching without sparkle. It also can adjust step-linear voltage or step-clipper voltage for a low-ripple PWM voltage output. By cascading the solid-state switch devices, which can be used to do linear adjustment or PWM modulation manipulation, between multiple-voltage output switching points which consist of battery and diode sets, it constructs a linearly continuous adjustment of PWM modulation output voltage circuit with low voltage as valley and second high voltage as peak. The circuit can adjust the voltage linearly from valley to peak or manipulate the low-ripple voltage output of PWM or raise the voltage slowly or lower the voltage slowly. It also can adjust the output of limited-current or fixed-current or fixed-voltage by feedback.

Title: Engine exhaust system with reduced hydrocarbon emissions
Inventor: JOHN PAUL DAI
IPC: F01N3/28
Filed: 1992-11-21
Granted: 1993-05-01
Abstract: An engine exhaust system is disclosed which in operation is capable of substantially reducing the quantities of hydrocarbons emitted to the atmosphere during engine start-up. The system utilizes molecular sieve means, such as a high-silica zeolite, which function to adsorb hydrocarbons emitted during engine start-up, before the catalytic converter has attained its effective operating temperature. The system is designed so that, once the catalytic converter has attained an effective operating temperature, the hydrocarbons can be desorbed from the molecular sieve means and conveyed to the converter for conversion to non-toxic by-products.

Title: Stepping motor driver
Inventor: WAKUDA HIROSHI
IPC: H02P8/36
Filed: 1996-02-26
Granted: 2001-10-21
Abstract: To rotate a stepping motor at a high speed without its step out. A control signal for determining the excitation pattern of an STM 1 is applied from a CPU 2 to an STM driver 2, and the STM driver 3 rotates the STM 1 by applying to the STM 1 a driving current responding to the excitation pattern. A current I flowing through the excitation coil of the STM 1 is converted into a voltage by a current sensing circuit 4 to be fed back to the CPU 2. For example, when attaching importance to the prevention of the vibration of the STM 1, the CPU 2 performs the switching of the excitation of the STM 1 in case of the energization current I exceeding a predetermined value, and also, when attaching importance to the large torque of the STM 1, the CPU 2 changes the excitation phase of the STM 1 in case of the energization current I reaching, e.g. a peak value.
