Title: Television signal transmitter
Inventor: OOKAWA SHINJI
IPC: H04N5/00
Filed: 1984-03-19
Abstract: PURPOSE:To decrease the number of transmission lines after securing the using and spare systems and to reduce the cost of facilities by using two types of intermediate frequency bands to synthesize the using and spare intermediate frequencies of a TV signal for transmission. CONSTITUTION:The inputs 1 and 2 of the 1st and 2nd TV signals are distributed to the using and spare systems by signal distributors 3 and 4. The frequency converters 5 and 8' convert frequencies into the 1st intermediate frequency band; while the frequency converters 6' and 7 convert frequencies into the 2nd intermediate frequency band respectively. These converters are connected to filter demultiplexers 13 and 14 which separate the 1st and 2nd intermediate frequency bands via filter synthesizer 11 and 12 which synthesize the 1st and 2nd intermediate frequency bands. Furthermore the frequency converters 15 and 18' which convert the intermediate frequencies corresponding to the 1st and 2nd input signals which are converted into the 1st intermediate frequency band and transmitted into a transmission frequency band are added together with the frequency converters 16' and 17 having the similar constitutions as converters 15' and 18 and convert the frequencies into the 2nd intermediate frequency band for transmission. Thus two types of intermediate frequencies are provided to perform the multiplex transmission with synthesization and distribution. In addition, both using and spare systems are connected alternately and therefore the 1st and 2nd input signals can be transmitted despite a defective transmission line.

Title: Character reading circuit
Inventor: HASEGAWA YOSHIYUKI
IPC: G06V10/98
Filed: 1980-04-21
Abstract: PURPOSE:To increase the character reading efficiency for a character reader using a hand scanner, by using two pairs of character reading means. CONSTITUTION:The characters equivalent to a line are read by two hand scanners 1, and the results of reading are stored in the buffers HB1 and HB2 respectively. However, in case the reading is impossible, an error code is stored. Each character read out of each of buffers HB1 and HB2 is compared with each other through the comparator C1. Then a character extracted out of the buffer HB1 is compared with the error code through the comparator C3, and a character extracted out of the buffer HB2 is compared with the error code through the comparator C2. When the outputs of comparators C1 and C2 are delivered, a character extracted out of the HB1 is delivered; while a character out of the HB2 is delivered when the output of comparator C3 is delivered respectively. And the output of the error code generator GEN is delivered when the output of comparator C3 is delivered. Accordingly the read output can be extracted in case either one of the two scanners performs reading. As a result, the reading efficiency can be increased.

Title: Circuit for operating high-pressure sodium lamp
Inventor: GIYUNTAA DETSURA
IPC: H05B41/392
Filed: 1992-03-12
Abstract: PURPOSE: To permit the modulation of light from a high-pressure sodium lamp and the change in color temperature at the same time by controlling the change in power supplied to the lamp in such a manner as to establish a specific relationship with the change in the duty cycle. CONSTITUTION: A control unit IV alternately makes semiconductor switches G2 and G3 and semiconductor switches G1 and G4 conductive in a bridge circuit III. A voltage pulse H generated in a down converter is applied to the circuit III through a rectifying circuit network I, and a current is supplied to a lamp L with a starter in a duty cycle controlled by the unit IV. An instantaneous current is measured by using a measurement resistor RM7 , and then a comparison unit VI makes a comparison between upper and lower bound values of a controllable average reference value U1. The pulse H is high-frequency modulated through the unit IV to control a current passed through the lamp L. In this constitution, a change ΔD in the duty cycle follows a change ΔP in the power supplied to the lamp L to satisfy the inequality ΔD/ΔP>0.  This can modulate light and change color temperature at the same time.
