Title: Magnetic recording and reproducing device
Inventor: KISHIMOTO ICHIRO
IPC: H04N5/91
Filed: 1994-03-24
Abstract: PURPOSE:To optimize the amplitude of an output signal of a magnetic head, to stabilize processing operation and to obtain a video signal with high quality by accelerating the response speed of an automatic gain control means and extending a control range. CONSTITUTION:Since an FM brightness signal and a low frequency chroma signal are included in a signal reproduced by a head pair 2, the chroma signal can be extracted by a filter 3. Because variation in a normal level is generated in the chroma signal, the variation of color density and the fluctuation of a color position will be generated if video signal processing is continued as it is. Thereby the amplitude of the signal is compensated by an automatic gain control circuit constituted of a variable gain amplifier 4 and a detector 5 in order to fix the level, the signal is converted into a high frequency chroma signal by a video signal processor 7 and the high frequency chroma signal is outputted from a high frequency chroma signal output part 8. Namely the circuit 6 is driven, and when the amplitude of an output signal from the amplifier 4 is made large, an output signal from the detector 5 is also made large and the gain of the amplifier 4 is reduced to fix the amplitude of the low frequency chroma signal.

Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent the abnormal sound of an upper guide member and the irregularity of a transfer image in the case of image formation, and to easily remove a transfer material remaining on a transfer material guide path in the case of a paper jamming, etc. SOLUTION: The base end part 21a of the upper guide member 21 is supported by an image forming device main body so that it can freely rock. When the member 21 is on a guide position side from a specified position where the tension direction of the member 21 by a tension spring 31 passes through the part 21a while a prescribed position is defined as a reference, the spring 31 presses the member 21 toward a guide position shown by (b). Thus, when a cardboard passes through the transfer material guide path M between a lower guide member 30 and the member 21, the member 21 is prevented from rocking, and the abnormal sound and the image irregularity caused by the rocking are prevented.  When the transfer material P remains on the member 30 by the paper jamming, etc., a process cartridge 11 is detached, the member 21 is rotated clockwise, and the transfer material carrying path is opened, so that the remaining material P can be easily removed.

Abstract: PURPOSE: To naturally ventilate the exhaust system for controlling overheat of a catalyst of an engine capable of a partial driving of the cylinders, by opening a shelter plate installed in the ventilation system to cool the system with the wind generated during running.  
     CONSTITUTION: A shelter plate 4 is fixed in front of an exhaust manifold 1 having a catalyst 3 of an engine with partially controllable cylinders. The plate 4, composed of guides 4a having many holes 4c, 4d, 4e on it and a movable plate 4b between the guides 4a, cuts off in-coming air during the normal running to increase the activity of the catalyst 3. Being fixed to a diaphragm 5a, the movable plate 4 is lifted, as negative pressure is introduced in a negative pressure chamber 5c, to let wind pass through the holes to the exhaust system. When the engine is operating with part of cylinders, temperature of the exhaust system rises due to an increase in load, but negative pressure in a suction pipe is introduced in the negative pressure chamber 5c, whenever the said temperature exceeds a preset level, by means of a device (not shown in the figure).
