Abstract: A vacuum accessory tool comprises a housing that defines a suction nozzle and a hair removal assembly associated with the suction nozzle. In one embodiment, the vacuum accessory tool further comprises an agitator assembly located in the suction nozzle and driven by an air turbine. In another embodiment, an impeller associated with the air turbine is weighted to prevent build-up of hair and other debris at the impeller.

Abstract: A kit and method for preparing a cleaning solution for delivery under pressure includes combining a cleaning composition, an oxidizing agent, an effervescent agent and an aqueous medium in a pressurizable container having an opening with a removably mounted cap. The effervescent agent reacts with the aqueous medium to generate a gas to pressurize the cleaning solution within the container. The method can be used for preparing a cleaning solution for use with a pressurizable container have an aerosol valve assembly or an extraction cleaner with a fluid delivery system for dispensing the cleaning solution under pressure to a surface to be cleaned. The cleaning solution and a pressurizable container having a removably mounted cap with an aerosol valve assembly can be provided as a kit to a consumer for preparing a pressurized cleaning solution.

Abstract: The invention relates to a work stand for supporting a variety of hair styling instruments in an organized manner. The work stand is formed by a base and a U-shaped supporting plate which is detachably carried by the base. The supporting plate has a plurality of cutouts extending from an outer edge inwardly to retain various hair styling instruments. Cylindrical holders for heated instruments, such as curling irons, are carried by the supporting plate, the cylindrical holders secured within apertures formed in the supporting plate. The supporting plate is provided with a pair of legs which are bent to extend under the bottom of the supporting plate and detachably slidably engage within respective bands secured to the base.

Abstract: A TTL-level BiCMOS driver comprises a oversaturation preventing part for preventing oversaturation in following parts including two diodes connected to each supply voltage, an inverter connected to the diodes and including a PMOS transistor and a NMOS transistor of which drain is connected to an input terminal; an inverter part connected to the oversaturation preventing part including a transistor and a diode connected to the emitter of the transistor and a resistor connected to the drain thereof and an inverter; and a switching part including first and second switching parts, the first switching part having an inverter connected to the input terminal, a PMOS transistor connected to the inverter, darlington transistors and a NMOS transistor connected to the base of one of the switching part having a transistor turned on according to the driving of the transistor in the inverter part and a NMOS transistor connected to the input terminal and a base of the transistor in the second switching part.

Abstract: A full-swing BiCMOS driver comprising an inverter for inverting an input signal, which includes two pairs of NMOS and PMOS transistors to invert an input signal and to prevent current leakage, a full-down controlling part for providing control signals, an output driving part for providing an output, and a delay-inverter for delaying and inverting the input signal which includes a delay part having two transmission gates to serve as resistors. According to the present invention, a full-swing BiCMOS driver which provides a full-swing logic value and prevents any additional power consumption by means of the delaying inverter.
