Title: Dc component reproduction circuit
Inventor: KAWABATA ETSUO
IPC: H04N9/72
Filed: 1990-03-28
Abstract: PURPOSE:To display a signal such as an ON-screen stably even at no signal by applying a pulse generated in the inside of a receiver in the absence of a horizontal pulse so as to make a black level on the screen constant. CONSTITUTION:When no horizontal pulse exists such as no signal input to a receiver, since a pulse detection circuit 20 detecting the pulse throws a changeover circuit 10 to the position of a horizontal pulse circuit for a pseudo horizontal pulse generating circuit 40 in the inside of the receiver, a horizontal pulse is applied to a DC component recovery circuit 30.

Title: Getting-on door device for elevator
Inventor: MIURA HIDETOSHI
IPC: B66B13/30
Filed: 1988-04-01
Abstract: PURPOSE:To prevent the demounting of a guide at the lower edge of a getting-on door from the groove of a sill even in the case when the getting-on door is expanded and contracted by heat, by allowing an emergent guide member to project into the groove by the urging power of a spring, when a stopper is molten by the heat of a fire disaster. CONSTITUTION:If a fire disaster occurs in the vicinity of the getting-on door of an elevator 1, the getting-on door 1 is heated, and the whole getting-on door 1 is extended in the vertical direction by the thermal expansion, and further heated, and when the lower edge of the getting-on door 1 contacts a sill 7, a rail slip-off preventing roller 4 pushes up a rail 2 by a reaction force, and the rail 2 begins to deform. During this time, a stopper 18 for suppressing the projection of an emergent guide member 15 reaches a melting temperature, and when the stopper 18 is melted, a guide rod 15 is projected into the groove of the sill 7 by a spring 16. Then, if the getting-on door 1 is cooled by the fire extinguishing water spray, etc., the getting-on door 1 starts to contract to an original length. Therefore, even if a common guide 6 is demounted from the groove 8 by the contraction, the emergent guide member 15 having a large projection quantity is set in the groove 8, and the demounting from the groove 8 is prevented.

Filed: 1983-05-10
Abstract: PURPOSE:To obtain an inexpensive position control device characterized by a simple constitution and the expanded range of general purpose utilization, by replacing all mechanisms for detecting regions by electric circuits, thereby omitting mechanism parts comprising limit switches and the like. CONSTITUTION:A memory device 10 and a comparator 11 are provided in place of a region detector in a conventional device. An angle adding signal is outputted from an adder 2 and stored in the memory device 10 for sampling. In the comparator 11, the present value of the adder 2 is compared with the previous value of the angle signal stored in the memory device 10 at every sampling period. When the difference is in the gradual increasing direction, it is judged that a closed loop is oscillated, i.e., the region of a potentiometer 6 is wrong, and a region switching signal is sent to a corrector 8. The corrector 8 performs the operation of an output from an A/D converter 7 in correspondence with a region A or a region B based on the region switching signal and sends the result of the operation to the adder 2. Thereafter the same procedure as that of the conventional device is performed. A rotary mechanism part 5 is set at an angle of a command input device 1.

IPC: G06F1/20
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To restrain an electronic device front deteriorating in cooling properties by a method wherein a box where fans are housed is so partitioned with walls as to house the fans separately one by one. SOLUTION: A fan box 8 is completely partitioned with thin plate walls 8a so as to isolate fan units 9 from each other. The fan unit 9 is prevented from being influenced by the adjacent fan unit 9 in the fan box 8, so that the circulation of cooling air is prevented from being impeded by the broken fan unit even if one of the fan units 9 gets out of order and stops operating and on the other hand, the circulation of a cooling air is impeded by the broken fan unit located in a path of cooling air in a conventional technique. Therefore, a reduction in the cooling performance of a cooling structure of this constitution can be minimized, and adjacent fan units are restrained from being influenced by each other.
