Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To wisely decide which method is to be compiled and which method is to be left in an analysis state by compiling the method when the number of calls on the selected method exceeds a threshold. SOLUTION: When a byte code 144 is supplied to a computer system 146, the byte code 144 can be processed by an interpreter 148. The byte code 144 can be compiled and a compilation code can be generated by a compiler 150. Whenever a method is called, the byte code 144 on the method is analyzed by using the interpreter 148. A means for analyzing how many times the method is analyzed is maintained and how many times the method is analyzed can be tracked by using an arbitrary and appropriate means. When the number of times for analyzing the method exceeds the threshold, namely, a limit value, the method can be compiled by using the compiler 150.

Title: Video signal transmitter and video signal receiver
Inventor: INOUE NAOYUKI
IPC: H04N19/00
Filed: 1994-12-22
Abstract: PURPOSE: To send/receive two kinds of video signals whose luminance and color difference signals have a different sampling rate while selecting any of them by multiplexing a synchronization pattern signal for a horizontal blanking period with a prescribed period. CONSTITUTION: When a frequency of a 1st luminance signal is 74.25MHz and a frequency of a color difference signal is 37.125MHz, a synchronizing signal multiplex circuit 2 multiplexes a synchronization pattern signal onto a signal for a horizontal blanking period for a period of 1/33.75kHz. When a frequency of a 2nd luminance signal is 75.524MHz and a frequency of a color difference signal is 37.762MHz, a horizontal blanking circuit 4 eliminates part of the horizontal blanking period and the frequency rate is converted into the same frequency rate as the case above, and a synchronizing signal multiplex circuit 5 multiplexes the synchronization pattern signal for the horizontal blanking period for each of a period of 1/47.203kHz.  A video signal changeover switch 6 is used to select an output of the synchronizing signal multiplex circuit 2 or 5 and the output is given to a 1.485Gbps serial transmission circuit 7. Part of the signal for the horizontal blanking period is decoded by the reverse operation to above to restore the signal into the original signal by the receiver side.

Abstract: PURPOSE:To improve a data rate by providing a switch to select one of plural switch matrixes in each column array, equipping a means to control the switch matrix, the switch and a phase shifter, effectively utilizing an antenna aperture and simultaneously forming plural beams. CONSTITUTION:When a number N of the column array is caused to be 24, the range of column arrays 1-1-1-8 is connected to a switch matrix 3-1 and the range of column arrays 1-9-1-16 is connected to a switch matrix 3-2. Then, the range of column arrays 1-17-1-24 is connected to a switch matrix 3-3. Thus, the three beams can be formed simultaneously. Namely, SP3T switches 2-2-2-24 in the column array side can arbitrarily select the switch matrixes 3-3-3-3 and the switch matrixes 3-1-3-3 can arbitrarily select the column arrays 1-1-1-24. Thus, since control is executed by a control part 6 so that mutual interference can not be generated, formation from the single beam up to three beams at miximum can be executed. A beam direction can be arbitrarily changed by the control of the switch.
