Title: Multi-synchronizing sign reproducing apparatus of a digital television
Inventor: KWON HO-YOL
IPC: H04N5/073
Filed: 1985-03-30

Abstract: This invention relates to a device which generates mutisynchronous signals at the digital television system.  In the coventional digital TV sysntem, data-lines corresponding to the bits are needed for the signal processing, and the prior system has disadvantages of the many connecting-lines.  At the window generating-circuit the time-delayed window-signal is made for vertical synchronious signals, and the mutil-synchronious signals are only extracted at the muti-color CO.. Thus the ring-counter consisting of the shift-registers generates the muti-synchronious signal.

Granted: 1988-12-17
Abstract: By measuring selected parameters of portions of input signal, feeding signal to unit under test and monitoring output to be compared with input, this method automatically evaluate the audio characteristics of selected parts in the audio and video program. A segmented signal train is recorded, in real time, on lead-in and lead-out areas of a pre-mastering tape.  The recorded test signals are played back, in real time, and a representation is stored in a memory of each test signal.  The selected test signal is recirculated repeatedly through the memory.  A continuous representation is produced of the selected test signal.  A signal analysis is performed of the continuous representation of the selected test signal.

C for 0.5-2 hrs; (d) cooling to normal temp. with air; (e) heating and maintaining at 850-900 deg. C for 2.0-5.0 hrs; (f) cooling and maintaining at 150-200 deg. C for 1.0-2.0 hrs; (g) cooling to normal temp. with air.

Title: Pwm generator
Inventor: KANG MIN-KOO
IPC: H03K7/02
Filed: 1991-01-30
Granted: 1996-06-05
Abstract: The PWM signal generating circuit generates a unipolar pulse width modulated signal by the steps as follows : after setting a new width of pulses by a software that calculates "!pulse width! - maximum" to the PWM+, PWM- from a bipolar pulse width modulator, a high voltage control signal A+ for a condition (reference voltage Vref > 0) and a low one A- for (Vref < 0) is transmitted to OR gates OR1, OR3, OR2, OR4. The PWM+ is produced as an unipolar pulse width modulated signal (PWM+)' for the former condition and the PWM- is produced as a (PWM-)' for the latter condition. The circuit reduces cost by just adding a simple software and a logic circuit to the existing bipolar pulse width modulator.

Title: Surgical reamer
Inventor: BORZONE ROCCO R
IPC: A61B17/56
Filed: 1991-02-01
Granted: 1993-04-26
Abstract: The cutting head 10 for a surgical reamer has a leading end 12 for insertion into a bone canal 60 and a trailing end 13 for attachment to a drive shaft 16. The cutting head has a cutting surface formed about an axis of rotation of the cutting head. The cutting surface is formed by the rotation of the cutting edges on a plurality of flutes 20 spaced around the axis of rotation. Each cutting edge has a first portion 26 spaced a predetermined radial distance from the axis of rotation at the tip portion 22 and terminates at a terminating point 30 which is at a greater radial distance from the axis of rotation than the starting point 28. The cutting edge on each flute 20 has a second portion 32 having a starting point 34 at the trailing end 24 of the cutting head 10 which is at a second predetermined radial distance from the axis of rotation. The second portion 32 extends axially towards the tip portion 22 and terminates at a point 36 at a greater radial distance from the axis of rotation than the starting point 34 thereof. A third curved portion 38 starts at the terminating point 30 of the first portion 26 and terminates at the terminating point 36 of the second portion 32 and intersects the first and second portions tangentially. <IMAGE>

Title: 가변성 오리피스 센터플로우 디스펜서
IPC: A47K10/24
Filed: 1991-06-27
Granted: 1999-06-15
Abstract: 다양한 중량, 폭, 부피 및 인장강도를 갖는 두루마리지 제품을 적용할 수 있도록 공급 오리피스의 직경을 변화시키기 위한 수단을 포함하는 두루마리지 제품공급용 센터플로우 디스펜서를 공개한다. 이 디스펜서는 리어 하우징에 피봇 연결된 프론트 하우징을 포함하고, 리어 하우징은 지지체 또는 저부 하우징으로부터 연장되어 배치되며, 여기에 두루마리지 제품이 놓이게 된다. 한 실시태양에서, 지지체는 주변에 배치된 서로다른 직경을 갖는 다수의 오리피스가 설치된 회전가능한 디스크에 부착되어 있다. 
     디스크는 각 오리피스가 지지체의 출구와 수직 오버랩 상태가 되도록 회전할 수 있다. 이와 같은 방법으로, 공급되는 특정한 종이 제품에 맞게 원하는 오리피스를 선택할 수 있다. 
     제2의 실시태양에서는 그안의 각 오리피스의 직경이 서로 다른 교환가능한 U-형 부재를 제공한다. 원하는 오리피스를 갖는 특정한 U-형 부재를 공급하는 종이제품용으로 선택하여 지지체의 출구에 대해 수직으로 오버래핑하여 삽입한다. 
     이들 양 실시태양에서는 오리피스를 변화시키는 수단을 지지체에 수동식으로 삽입하고 배낼 수 있는 드로어상에 설치한다. 드로어 부재는 V-형 개구부를 포함하며, 이 개구부는 드로어를 잡아당길 때 지지체의 출구와 실제로 수직 얼라인먼트로 움직여서 드로어는 열린 상태가 되어 공급되는 종이 제품의 리드단부를 용이하게 삽입할 수 있다. 일단 리드단부가 삽입되면, 드로어 부재는 닫혀져서 종이 제품의 리드 단부는 선택된 오리피스에 둘러싸이게 된다.
