Title: Method for transmitting data through optical fiber line
Inventor: BRAMS MARTIN
IPC: H04B10/556
Filed: 1989-03-07
Granted: 1992-03-06
Abstract: A method for inserting an additional channel into a main channel during the transmission of data between two stations via optical waveguides is specified. For this purpose, bits of the optical additional channel are inserted with a bit rate which is lower compared with the main channel at an arbitrary position in each case in place of a double bit at defined intervals which are known in the transcoder of the receiving station into an optical main channel originating from the transcoder of the transmitting station and removed again from the optical main channel at the receiver end. The bits of the additional channel inserted into the main channel are double bits which are equal to an illegal bit combination which is obtained during the recoding of the electrical AMI code into the optical CMI code. At the receiver end, the double bits of the main channel, replaced by the bits of the additional channel, are recovered by means of a sequential logic as determined by the rules of the electrical code.

Abstract: When a paper is  jammed  within  a  copy  machine,  a  sensor detects the position of the jammed  paper,  and  the  position  is displayed. If the position of the jammed paper is  placed  at  the outside of a cleaner, the jammed paper is ejected to  the  outside of the machine by forwardly driving a main motor,  and  then,  the jam display is terminated to return the copy machine to the normal operation. If the jammed position is placed  inside  the  cleaner, the jammed paper is taken out from the cleaner by driving the main motor reversely, and then, the paper is ejected to the outside  of the copy machine by driving the main  motor  forwardly.  Then  the display is terminated, and the machine is restored to  the  normal operation.

Abstract: The transition of clock-pulse which is retiming the  inputted NRZ data generates in unit interval of data bit. The transition of clock- pulse is not  automatically  adjusted  and  depends  on  the accuracy and temperature character  of  device.  And,  self-tuning retiming circuits have shortcomings of the limitation of bit-speed and of the gitters. By comparing the phase of retiming clock-pulse and unit interval of inputted  data  bits,  compared  results  are given digitally  for  the  phase  detector  which  outputs  phase information easily matching digital circuits.

This circuit includes an amplifying part (28) regulating amplification gain; and a disturbance light sensor (50) modifying an integrating part (29) that can vary integrated resistance, sensing and processing a disturbance light. The present invention prevents the amplifying part (28) from saturating by reducing the amplification gain during short-distance automatic focus regulation, and controls the integrated action time to be within a given range to perform an automatic focus regulation. If the disturbance light is received while a reflection signal is small or does not exist during long-distance automatic focus regulation, this circuit increases the amplification gain, and the disturbance light sensor (50) senses the increase in the DC output voltage of a current-voltage converter (22) to raise the integrated resistance and increase the integrated action time longer than a given range so that its microcontroller (10) can perform a long-distance automatic focus regulation of a driving motor.

Title: Status test circuit of video buffering validation
Inventor: LEE GAENG GOUN
IPC: H04N19/152
Filed: 1992-12-31
Granted: 2000-09-15
Abstract: PURPOSE: A state testing circuit of a video buffering identifier is provided to obtain a uniform image quality on the entire screen by regulating channel buffer state through estimation of coded data generation. CONSTITUTION: A variance unit(40) calculates frame change of each image type required for bit allocation. A bit allocator(30) estimates a coding bit number for the next VLC(variable-length coding) image from the output of the variance unit(40) to prevent overflow and underflow. A buffer(20) receives the VLC coding data and informs the underflow/overflow state beforehand to prevent overflow and underflow. A Qp controller(10) prevents overflow and underflow according to the output of the bit allocator(30) and the buffer(20).

Title: Incinerator
Inventor: BAE YONG-TAE
IPC: F23G5/46
Filed: 1993-01-25
Granted: 1996-05-01
Abstract: The apparatus includes a combustion chamber(12) in which an upper gas outlet pipe of an incinerator(1) having a hot well(15) on its main wall is mounted under a stove pipe of a dust collector(3), vent pipes(15'), and a secondary recombustion chamber(12') formed in the combustion chamber. By the recombustion, waste tires can be combusted perfectly.

Title: Scoring circuit of karaoke system
Inventor: BYON TAE-GYU
IPC: G11B20/02
Filed: 1993-01-27
Granted: 1995-09-14
Abstract: The scoring circuit in video song accompaniment machine comprises an amplifier for amplifying the sound signal input to a sound signal input terminal; a comparator for comparing the amplified signal with a reference generated from a reference signal generating circuit and detecting only the input sound signal; and a monostable multivibrator for generating pulse signals corresponding to beats and inputting them to the micom.
