Title: High frequency lighting device
Inventor: INOUE AKIHIRO
IPC: H01J65/04
Filed: 1993-06-14
Abstract: PURPOSE:To provide a high frequency lighting device for changing the frequency of a micro-electromagnetic wave supplied to a discharge container and switching brightness and/or the impression of light emission. CONSTITUTION:High frequency electromagnetic wave generated by a high frequency generating device 2 is supplied to a discharge container 10 in which discharge medium is sealed through an antenna 15. The frequency of high frequency electromagnetic wave to supplied to a discharge lamp is selected from a frequency less than 300MHz to a frequency 300MHz or more by a switch 22. Thereby, when the frequency of microelectromagnetic wave applied to the lamp is less than 300MHz, a positive column contracts toward to the center part of a discharge space and the positive column expands when the frequency is over 300MHz. Accordingly, the since the configuration of the positive columns changes if the frequency is switched, the illuminous image such as brightness may be changed.

Title: Data line changeover controller
Inventor: KARASHIMA YUKIE
IPC: H04L69/40
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To reduce the time for re-transmission of data by configuring the controller with a reception changeover means that selects a standby line for the reception so as to receive delayed data thereby switching the line without aborting the data. SOLUTION: An active transmission section 103 sends data with an error detection signal added thereto by an error detection signal provision section 102 to an active line and a delay section 151 gives a prescribed delay to the signal and a standby transmission section 113 sends the delayed signal to a standby line. Reception sections 221, 231 at a receiver side receive signals from both the lines and error detection sections 222, 232 detect an error. The result of detection is informed to an information processing section 101. Upon the receipt of the notice of presence of an error in active data, the information processing section 101 allows a changeover section 223 to select a standby line for the reception. Thus, the same data as the data whose error is detected in the active line are received by the standby line with a delay.

Title: Digital msk modulator

Filed: 1982-08-20
Abstract: PURPOSE:To eliminate both analog and storage parts with no need of regulation, by generating digitally the keyed frequency and then obtaining continuous phases with a combination of the present data and its immediately preceding data. CONSTITUTION:For frequencies fH and fL which are keyed in by an input data, the frequency fL is set an integer-fold value compared with the clock frequency of data, i.e., as fL=M1.fCK (M1: an integer). While the frequency fH is set as fH=(M1+1/2).fCK (fCK: clock frequency of data velocity). Therefore the fL is obtained by giving division of (2M1+1) to the clock obtained by multiplying the clock frequency of data velocity by the least common multiple of 2M1 and (2M1+1); while the fH is obtained by giving division of 2M1 to said clock frequency. In this case, inverted fL and fH are generated at a time; and a selection is carried out to obtain the phase continuation in response to the input data. Thus an SMK (minimum shift keying) wave is obtained with phase continuation.
