Abstract: A cathode ray tube comprising a curved substantially rectangular display window, the outside surface and/or inside surface of the display window being given by: z=f(X, Y) where each point situated off the x-axis and the y-axis complies with the formula - 2ROOT (zxxzyy)<zxy/signXY<0. where zxx= DIFFERENTIAL 2z/ DIFFERENTIAL X2, zyy= DIFFERENTIAL 2z/ DIFFERENTIAL Y2 and zxy= DIFFERENTIAL 2z/( DIFFERENTIAL X DIFFERENTIAL Y) signXY=+1 for X*Y>0, and signXY=-1 for X*Y<0. An improved reflection image of linear light sources is obtained.

Abstract: Disclosed is a manual gear having forward 6 stages and backward 2 stages for a car.  The gear comprises input and output portions.  The input portion includes a forward 1 stage gear, a forward 2 stage gear, a backward 1 stage gear, a backward 2 stage gear, a synchronizer for forward 3 and 4 stages and a synchronizer for forward 5 and 6 stages.  The output portion includes a synchronizer for forward 1 and 2 stages, a synchronizer for backward 1 and 2 stages, forward 3, 4, 5, 6 stage gears.  Thereby, the fuel consumption can be reduced and the drive condition can be optimized, according to the precise gear stages.

Abstract: 방송채널의 셋팅시 지역마다 상이한 채널번호로 인하여 혼란을 겪게 되므로 채널번호의 선택 대신에 방송국명에 따라 채널이 셋팅되게 하므로써 지역에 관계없이 편리하게 방송채널을 선국할 수 있도록 한 것으로 채널 셋팅 모우드 인가를 판단하여 전체 채널중 방송중인 채널만을 탐색 기억하는 단계와, 방송국키 입력을 판단하여 전체 채널 데이타를 송신한후 메모리된 채널만을 디스플레이 시키는 단계와, 방송국키 입력이 '오프' 될때의 튜닝데이타를 방송국키 튜닝데이타로 기억시키는 단계로 이루어진 것으로 방송국명에 따라 방송채널이 자동 선국되어지는 편리함이 있다.

Title: Fixed voltage power system with a switching
Inventor: CHONG IL-HO
IPC: H02M3/155
Filed: 1992-10-10
Granted: 1995-09-14
Abstract: The system consists of an oscillating circuit which oscillates to output reference frequency, an inverter which inverts the phase of the output voltage of a voltage comparing unit, a switching unit which swtichs by the output voltage from the inverter, an inverter which converts the phase of output voltage from the inverter, a switching unit which controls the voltage from a trans former, a diode which rectifies half wave of the output voltage from the trans former, a variable resistor which controls the level of the output voltage of the diode, a zener diode which compares the voltage at a variable resistor with a zener voltage, and a voltage comparing unit which controls the switching unit by outputting a control voltage.
