Title: Working state confirming system for action controller of control panel
Inventor: FUKUHARA MASANORI
IPC: G09F9/00
Filed: 1989-02-16
Abstract: PURPOSE:To confirm whether or not an operating command is normally carried out by using a means to receive an action start report signal from an action controller (sequencer) and to display it and a means to receive and display an action end report signal. CONSTITUTION:When a sequencer receives an action command and starts a forward action of a belt, for example, the sequencer sends an action start report signal via a microcomputer system. This signal is received via a control panel POD and a fact that the sequencer actually started an action is displayed by performing the reverse display (reverse of color) of a numeric character '4,000' set adjacent to the left of a 'forward' part. In the same way, the action end report signal is received via the panel POD when the sequencer is through with its forward action. Then a numeric character '4,010' adjacent to the right of the 'forward' part is reversed and displayed. Thus it is possible to confirm via the panel POD whether or not an operating command is normally carried out or not.

IPC: H04B1/50
Filed: 1978-03-27
Abstract: PURPOSE: To provide a modulator and a multiplier with narrow-band characteristics by using the output of a multi-frequency signal source as a local oscillation signal of a receiver directly and by shifting it by a modulated wave twice as much as an intermediate frequency for the use as a transmitting frequency.  
     CONSTITUTION: The output of frequency (fL) of synthesizer SZ, a multi-frequency signal source, is supplied to mixer MX 1  at the receiver side directly and then used as a local oscillation signal directly. On the other hand, SZ generates an output of frequency (fS), which is modulated and multiplied by multiplier MP 3  to frequency (m.fS) twice as high as intermediate frequency (fI) before being supplied mixer MX 2  where a frequency shift is made. By MX 2 , a difference betweem both frequencies is obtained and the output of SZ is shifted to the low-frequency side by a frequency twice as high as (fI). This frequency is used as transmitted frequency (fT). As a result, relation of fI=fR-fT is born even if (fL) of SZ changes, assuming that (fS) of SZ and multiplier (m) develop relation of m.fS=2.fI.
