Title: Signal supply device
Inventor: MARUYAMA ATSUSHI
IPC: H04N7/16
Filed: 1994-09-30
Abstract: PURPOSE: To eliminate the use of an exclusive adaptor or a headphone and a complicated device and to reduce the cost of a signal supply device by providing a constitution where a passenger control panel partly inhibits the selection of channels performed by a channel selection means and also cancels this partial inhibition of the channel selection in response to the received remote control signal. CONSTITUTION: Plural voice data reproduced by an audio signal reproduction unit 1 are sent to a program transmission unit 2. Then these voice data are digitized and diversified and supplied to plural passenger control units 3x. When a passenger operates a channel selection key on a switch panel 16, a control part 6x gives a command to a demultiplexer 12 to fetch the data on the necessary channels. Then the part 6x decides whether the remote control input is received or not. If received, the part 6x decides whether the ID of the seat confirmation information on the input remote control signal is coincident with the ID of a seat. If coincident, it is decided whether the input data are equal to a code that permits the hearing of the charged channels. If decided so, it is decided that the input data are equal to a code that inhibits the hearing of the charged channels.  Under such conditions, the selection is inhibited to both channels 9 and 10 and a normal operation is carried out.

Filed: 1992-09-04
Abstract: PURPOSE:To provide a novel method for adjusting the value of resistance for a thermal head without changing the shape of heating resistors and with a good thermal stability and a reduced unevenness of printing density. CONSTITUTION:A probe is brought into contact with a conducting part leading to heating resistors of a thermal head 7 consisting of the resistor materials of predetermined film thicknesses and, after application of voltage pulse from a pulse generating circuit 10, the resistance value of the heating resistor is measured by an ohmmeter 11. If the resulting resistance value is at least a predetermined one, the voltage pulse is made higher in crest value and applied through the probe to reduce the resistance value and, if it is less than the predetermined value, the application of this voltage pulse is stopped, whereby variations in the resistance values of a number of heating resistors are adjusted to be within 3% in terms of absolute value.
