Title: Terminal control system
Inventor: WATANABE YUICHI
IPC: H04N1/00
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent the temporal passing of a controller and a terminal equipment at the time of shifting to a power saving mode by providing a transmission means for responding to the transmission of a power saving mode shifting request and transmitting the report that power saving mode shifting is possible from the controller to the terminal equipment, etc. SOLUTION: At the time of receiving the power saving mode shifting request, a personal computer(PC) 3 promptly releases acquired resources. When all the resources are released, a power saving mode shifting possible report is transmitted from a transmission part. At the time of receiving the power saving mode shifting possible report from the PC 3, a composite terminal equipment 1 confirms power saving mode shifting conditions again since it is possible that the respective resources of a composite function terminal main operation part 5 are used as a single body after the power saving mode shifting request is transmitted until the power saving mode shifting possible report is received. Thus, the interface error that the terminal equipment 1 goes into the power saving mode while the PC 3 transmits data or the like is prevented.

Filed: 1986-02-28
Abstract: PURPOSE:To obtain a controller for a highly safe, hot air heating apparatus of combustion type, by providing the apparatus with a safety shut-off device which outputs a signal to stop combustion of a burner because ventilation is not performed, when the room temperature detected by an inclination detector does not show a specified inclination, or the room temperature does not come down below a predetermined threshold value. CONSTITUTION:At the same time when a signal to actuate ventilation is output from a ventilation timer part 26, a signal is fed into a safety timer part 30 as well to start the safety timer. The safety timer part 30 judges whether ventilation is actually performed or not within a predetermined time after the signal for ventilation is output. If ventilation is not performed by the time when the safety timer 30 cycle is completed, a safety shut-off part 31 is driven to shut off a safety valve 10, so that combustion is stopped. The safety shut-off part does not function when the safety timer part 30 judges that ventilation is performed before the cycle of a safety timer 30 is completed. Accordingly combustion is continued, and the ventilation timer part 26 starts counting again. The safety shut-off part 31 judges whether ventilation is performed so as to be instructed or not by the inclination of room temperature, detected by an inclination detecting part 25.

Title: Magnetic recording and reproduction system
Inventor: KITAMURA SADAFUMI
IPC: H04N9/87
Filed: 1979-04-11
Abstract: PURPOSE: To make it possible to correct signal absence of an one-head VTR by correcting a period when a reproduced signal is absent in reproduction by a signal repeating a reproduced signal of an 1H period right before the period.  
     CONSTITUTION: The reproduced signal of rotary ceramic head 1 is applied to FM detecting circuit 4 by way of head amplifier 2 and limiter 3 to obtain a video signal. Signal-absence-period detecting circuit 5, on the other hand, detects the absence period of the output FM signal of amplifier 2 and its detection pulse drives change- over circuit 6. When there is no detection pulse input, this circuit 6 allows the output signal of circuit 4 to pass through as it is and when the detection signal is input, a signal having passed through 1H-period delay circuit 7 is output. Consequently, the continuation of the signal is secured and video output signals without any absence period are obtained at output terminal 9 via amplifier 8.
