Title: Black level correcting circuit for video signal
Inventor: SAWACHI YOICHI
IPC: H04N5/18
Filed: 1991-01-18
Abstract: PURPOSE:To improve the contrast with an inexpensive and simple circuit even when flare or the like takes place. CONSTITUTION:A clamp circuit 37 clamps a luminance signal Y so that a peak level of a black level pulse BP mixed by a pulse mixer 36 is fixed to a pedestal level.

Title: Automatic spiking device
Inventor: TSUBOTA KENZO
IPC: B60C11/16
Filed: 1986-01-28
Abstract: PURPOSE:To make a spike pin rise or retract from or to the ground plane of a tire and thereby prevent a slip and damage to a road surface from occurring, by letting both electric currents repelling each other and vice versa selectively flow into an interval between an electromagnet and plural permanent magnets installed inside the tire ground plane. CONSTITUTION:When the switch installed in a driver's seat is operated and an electric current is made to flow so as to cause an electromagnet 1 and each of permanent magnets 2 and 6 to be repelled to each other, the permanent magnet 2 moves so as to extrude a spike pin 3 to a tire ground plane. And, the permanent magnet 6 is separated from the electromagnet 1 whereby it pulls back a stopper 5 to clamp the spike pin 3, while it presses a stopper 4 to the spike pin 3. Therefore, the spike pin 3 is locked there in a state of being projected to the tire ground plane, thus a nonskid effect is brought into full play. On the other hand, when if the current is made to flow so as to cause the electromagnet 1 and these permanent magnets 2 and 6 to be pulled to each other, the spike pin 3 is locked in state of being retracted into the tire ground plane, so that any damage to a road surface can be prevented.

Abstract: PROBLEM TO BE SOLVED: To collect and recover fluid leaking from the pipe junction part of pipe passage. SOLUTION: A cover device comprises a first cover body 1 and a second one 3 for enclosing a pipe junction part, and two pieces of packing 5 held between flanges 2 and 4 in both cover bodies. The second cover body 3 is formed with a drain bore 6 and an inclined wall 34, through which another drain bore is formed. The fluid leaking from the pipe junction part is first collected in the space defined by the first and the second cover bodies 1 and 3, and is then recovered outside through the drain bore 6 and another one formed through the inclined wall 34. The packing pieces 5 are formed on both their sides with plural projections 51, while the flanges 2 and 4 are formed with plural projection insertion holes 22 and 42.  The packing pieces 5 are held between the flanges 2 and 4 with the projections 51 being inserted into the projection insertion holes 22 and 42 to temporarily fix both cover bodies 1 and 3 on each other against their separation from each other. That process facilitates the mounting of the cover bodies 1 and 3 fastened together at their flanges 2 and 4 to the pipe joint by a fastener, which may be done by a single person.

Title: Controlling method of brushless motor
Inventor: OGAWA YOSHIAKI
IPC: H02P6/08
Filed: 1995-01-09
Abstract: PURPOSE: To prevent the false detection of the position of a rotor and to make rotation control stable by calculating a mask end time n the basis of a period of detection of the position of the rotor, the last time of detection of the position and the present OFF time of a chopping cycle. CONSTITUTION: On the occasion when the present detection of the position of rotor 3a is executed on the basis of the result of the comparison of a terminal voltage R of an armature winding with a reference voltage after the last detection of the position, the time of the end of the mask prohibiting detection of the position is calculated on the basis of a period of position detection (corresponding to the number of revolutions), the last time of position detection and a chopping OFF time (corresponding to an impression voltage of a brushless motor 3). When the mask end time comes, the present detection of the position is permitted and the detection of the position is executed at the regular time of position detection.  Only when the point of intersection of the terminal voltage of the armature winding and the reference voltage (the present time of position detection) is larger than the mask end time, the present time of position detection is judged to be a regular timing of position detection.
