Title: Image recorder provided with heating roller fixing device
Inventor: SASAKI HIROBUMI
IPC: G03G15/00
Filed: 1990-04-27
Abstract: PURPOSE:To efficiently and consecutively perform the copying of a large number of sheets by switching a set temperature at which a copying action is stopped or lowered by a temperature sensor corresponding to elapsed time from starting or a temperature detected by another temperature sensor. CONSTITUTION:In the case that an atmospheric temperature detected by the temperature sensor S2 is equal to or above the set temperature when the controlled temperature of the temperature sensor S1 is lowered to the 1st slowdown temperature because the copying action is continuously performed, a copying speed is immediately made to slow down by judging that the temperature of a heating roller 10A is detected by the sensor S1 in a normal state and then it is switched to an ordinary speed at the time of recovering to a restored temperature. By judging that the detection of the temperature is not normal when the temperature detected by the sensor S2 is equal to or under the set temperature, the copying action is continued until the temperature is lowered to a 2nd slowdown temperature which is much lower, and a mode is not switched to a copying mode in which the copying speed is caused to slow down until the temperature gets equal to or under the 2nd slowdown temperature.

Title: Cyclic type noise reduction device
Inventor: KATAGIRI TOSHIYUKI
IPC: H04N5/21
Filed: 1986-05-19
Abstract: PURPOSE:To suppress a remaining image easy to appear at an animation by comparing the inputs of an input attenuator circuit and a feeding-back attenuator circuit, judging that the animation is obtained when the difference in both inputs exceeds the constant value set beforehand and then, mixing an input video signal and an output video signal with a prescribed ratio. CONSTITUTION:When an image formed by a video signal,which is the output of a magnetic recording reproducing circuit 10, is the image with a comparatively late action, the output of an animation detecting circuit 12 is at a low level, and a changingover switch 13a in a mixing circuit 13 is changed over to a changing-over switch 15 side. On the other hand, when the image formed by a video signal,which is the output of the animation detecting circuit 12, is the animation with the fast action, the output of the animation detecting circuit 12 comes to be a high level. Therefore, the changing-over switch 13a in the mixing circuit 13 is changed over to a changing-over switch 14d side. For such a reason, the input and output of a cyclic type noise reduction circuit 1 are added by an adder circuit 13b and attenuated to 1/2.

Title: Facsimile equipment
Inventor: NAMIKAWA MASANORI
IPC: H04M11/00
Filed: 1989-05-09
Abstract: PURPOSE:To prevent damage of a line switching circuit by discriminating a line detecting an incoming call based on a detection signal of a ringing detection means and selecting a line discriminated at a point of time when a prescribed time elapses from the detection end timing of a ringing pulse signal detected at first. CONSTITUTION:When a ringing pulse signal is outputted from an external line L1 and an extension L2, detection signals SD1, SD2 of ringing polarity inversion detection circuits 13, 15 are outputted to a CPU via an input circuit 14. A central processing unit is in standby till the detection signals SD1, SD2 descend and a prescribed time elapses to change over relays R1-R4. Since the switching operation of the relays is implemented for a period when no ringing pulse signal is generated, no large voltage is applied to contacts of the relays R1-R4. Thus, damage to the relays R1-R4 is prevented.

Abstract: PURPOSE:To save an electrical energy, extend a life of electrical component elements, prevent a speaker noise during non-voice period and prevent a generation of shock sound when an energization of the part relating to the voice output is turned on or off by a method wherein the part relating a voice output of a voice synthesizing device is energized during only a specific period in which a voice output is to be fed out and the energization for the remaining period is turned off. CONSTITUTION:In a control part, an energization control signal PWR is kept at a high level when the voice output is not required. Thereby, the transistor Q1 is turned off, a supplying of electrical power to a voice synthesizing device 5 and an amplifier 6 is turned off. In turn, a transistor 86 is turned on and a series connected circuit of capacitor 62 and resistor 63 is kept in its short circuited condition. Thus, a terminal 61f is drawn to a ground level and another input terminal 61e of the differential amplifier 61d is also pseudically drawn at a low level. Thus, a gain of the amplifier 6 is kept at a quite low condition. Even in the case that a shock signal is fed to the input terminal 61e of the amplifier 6 due to some reasons when the supplying of electrical power is switched, no shock sound is produced from the speaker 7.
