Title: Hair styling appliance and method of styling hair
Inventor: HENNINGER FRIEDRICH
IPC: A45D2/00
Filed: 1997-04-23
Abstract: PURPOSE: A hair styling appliance and a method are provided to apply the hair styling appliance, which allows the shaping of curls, with the diameter of the curls and thus the type or shape of curl being producible independently of the diameter of the hair winding portion. CONSTITUTION: A hair styling appliance is comprised of a circular-cylindrical heating portion(6) and a hair retaining clamp(8) which is urged against the heating portion(6) by a spring means. Starting from root level(14), a strand(2) of hair to be styled is inserted between the heating portion(6) and the clamp(8), the heating portion(6) heating the strand of hair to forming temperature along the contact surface(12) between the two components. On its one edge, a clamp(8) has an elongate styling edge(10) over which the strand(2) is pulled. When the user moves the hair styling appliance in the direction of pull(16), the heated strand(2) is drawn through the area between the heating portion(6) and the clamp(8) and, upon leaving the contact surface(12), a strand(2) is deflected on the styling edge(10) of the clamp(8); this shapes the strand(2) of hair into a curl from root level(14) to the tips.

Abstract: 본 발명의 제어 회로(30)는 인가되는 제어 전압에 응답하여 컨택터(10)의 코일(20)을 구동시킨다. 제어 회로(30)는 상기 제어 전압으로부터 조절된 출력 전압을 발생시키는 전원(31)을 포함한다. 타이머(34)는 상기 조절된 출력 전압의 온셋(onset)시에 그 동작을 개시하며 PWM 제어기(33)에 의해 발생되는 펄스들의 폭을 제어한다. 이들 펄스는 코일(20)에 제어 전압을 인가하는 트랜지스터(Q2)를 제어한다. 최초 이들 펄스는 코일(20)에 고 전류가 흐르도록 하여 컨택터(10)를 폐쇄시키고, 소정의 시간 간격 후에 타이머(34)는 PWM 제어기(33)에 신호하여 펄스의 폭을 짧게 함으로써, 보다 적은 전류가 코일에 인가되어 컨택터가 폐쇄 상태를 유지하도록 한다. 플라이백 회로(36)는 코일(20)과 병렬로 비교적 낮은 역 전압 강하 경로를 제공하여 펄스들 사이에 전자계가 유지되도록 한다. 컨택터(10)를 개방하기 위해 제어 전압이 제거되면, 플라이백 회로(36)는 높은 역 전압 강하 경로를 발생시켜 코일 전류를 신속하게 떨어뜨린다.

Abstract: PURPOSE: An apparatus for generating multi-carrier constellation signals is provided to replace many memory cells and logic circuits with one RAM, so as to simplify device configurations, to reduce manufacturing costs, and to perceive an optimum line characteristic in an initialization process so as to implement an optimum communication sub channel. CONSTITUTION: A storage(30) stores sub channels, the number of bits, power levels, constellation signals and data-related values, which are inputted from a transmission terminal in an initialization process. A serial to parallel(S/P) converter(10) converts data bit strings from received signals as the number of bits. A channel counter(16) counts the sub channels as to every sub channel converting signal included in the received signals, and transmits the counted sub channels to a first input selector(32). The first input selector(32) inputs input values of the channel counter(16), a bit/power value temporary storage(36), and the S/P converter(10) in the storage(30). A second input selector(34) supplies a signal for dividing a memory area of the storage(30) into a bit/power table and a constellation signal area. The bit/power value temporary storage(36) temporarily stores data related to bits and power inputted from the storage(30). An output signal temporary storage(38) generates a latch signal, to output constellation signal values only, from output signals of the storage(30). A controller(40) feeds back a bit and a power value of a first channel of the initialized storage(30) to the temporary storage(36), to temporarily store the bit and the power value. The controller(40) outputs a constellation signal according to selection signals of the first/the second selectors(32,34), and feeds back a bit and a power value of a next channel to the temporary storage(36).
