Title: Circuitry for allocating acess to a demand-shared bus
Inventor: GRIMES GARY JOE
IPC: G06F13/374
Filed: 1983-01-07
Granted: 1988-10-17
Abstract: The access  allocating circuit to a common collector line is used according to demand by a number of data terminals.  During the demand time each allocation requesting terminal transmits synchronously and sequentially the digits of a priority code associated with it.  The transmission to the collecting line starts with a highest digit. After application of all digits, only the demanding terminal with highest code remains in contention and occupies the collecting line. A better pirority facility for the terminals is obtained by a number of flip-flop in each terminal, generating the terminal parameters.

Title: Apparatus and method for detecting object in medium material
Inventor: MICHIKUCHI YOSIHIRO
IPC: G01S13/90
Filed: 1985-10-31
Granted: 1990-04-04
Abstract: A wave is transmitted toward an object present in a medium and the resultant reflected wave is received.  The received signal is multiplied by a reference signal so that the frequency of a signal component included in the received signal as a result of reflection is converted into a frequency which can be removed by a low pass filter.  The signal is then passed through the low pass filter and the output applied to a signal processor with the results shown on a display.  An oscillator generates the reference signal at the received signal frequency which is passed through phase shifter for multiplication.

Title: Ntsc & dal-m type auto selection circuit of vtr
Inventor: LEE SON-TAE
IPC: H04N11/20
Filed: 1985-12-28
Granted: 1991-05-25
Abstract: The circuit automatically selects the  reproduction  mode  of the NTSC and PAL-M modes in the VTR  so  that  it  reproduces  the program in the NTSC mode if the program is recorded  in  the  NTSC mode, and viceversa. When the receiving mode is set to  the  PAL-M mode, and the VTR reproduces the NTSC tape, the output signal of a colour signal processor IC (1) turns to the  noise  signal  having 0.7V amplitude. The noise signal is provided to set  terminal  (5) of a flip-flop (3) through a  low  pass  filter  (2),  and  output terminal (0) of the flip-flop turns to high level from  low  level so that the receiving  mode  is  changed  to  the  NTSC  mode.  In opposite case, the process is similar, then the user does not have to select the reproduction mode manually.

Abstract: The method for obtaining the large  capacitance  in  a  small area by forming a trench on a word line  comprises  the  steps  of forming a word line (101) and a cap LTO layer (107) on  a  silicon substrate (100) having a field oxide  film  (111)  and  an  N-plus region (112)  to  deposit  a  LTO  layer  (106)  thereon,  forming trenches (108,109) and a contact (110) by using photo and  etching proesses to form a word line cap LTO  (107'),  forming  a  storage node (103), a capacitor insulator (104) and  a  plate  (105),  and forming a capacitor by using photo and etching processes.
