Title: Launching cylinder shape of underwater launcher
Inventor: ARAKI TOSHIMITSU
IPC: F41F3/08
Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To alleviate a bending force to be applied to an underwater runner when launched by smoothly enlarging an inner diameter of the vicinity of a launching port of a launching cylinder toward a launching direction in an underwater launcher having the cylinder to open a launching port at a shell in a lateral direction of a submarine. SOLUTION: In the case of launching an underwater runner 2, first a first extending or retracting drive means 15 is retracted to open a front door 5 to open a launching port 4. Then, since a submarine 10 is voyaged, a relative water flow 29 directed from forward to rearward of a propelling direction 13 is near the port 4, and a lateral force is operated at the runner 2 extended at its neck from the port 4 in a launching direction. Therefore, the runner 2 has a fear of bringing a downstream side face into contact with the port 4. Then, a flared tube 30 smoothly flared in its inner diameter toward the launching direction is formed near an end of a launching cylinder 3 so that the runner 2 is not engaged within the cylinder 3 in such a manner that the runner 2 can be smoothly launched.

Inventor: KINUHATA HIROSHI
IPC: B29D30/68
Filed: 1987-12-19
Abstract: PURPOSE:To process a desired pattern groove to a tread surface, by mounting a contact member for allowing a cutter to protrude corresponding to the predetermined depth of a pattern groove and providing an elastic member energizing the cutter between a cutter clamp and a cutter support frame in a direction for bringing the same into contact with a tire to move the cutter by an elastic member apart from the movement of a cutter support apparatus so as to follow strain. CONSTITUTION:A tire 3 is mounted on a tire support stand 2 and positioned by moving a support truck on a rail 21 in an X-axis direction by an operation apparatus not shown in a drawing and moving the same on a rail 22 in a Y-axis direction. When the tread surface of the tire 3 is distorted and unevenness is generated from a reference surface shown by one-dot broken line, since a contact member 12 is brought into contact with the tread surface, a cutter clamp 86 allows an elastic member 9 to extend and contract corresponding to longitudinal vibration due to the unevenness to allow a cutter 10 to always move up and down so as to follow the tread surface and the depth of a groove to be formed is kept constant to prevent the generation of a shallow or deep part in the groove.

Title: Automatic equalizer
Inventor: MITA SEIICHI
IPC: H04N5/93
Filed: 1988-12-23
Abstract: PURPOSE:To extremely accurately detect only an equalization error generated in a recording/reproducing system by simultaneously supplying the output signals of a transversal filters to two juxtaposed comparators, discriminating the signals by means of one comparator, changing a reference level by means of the other comparator, and detecting the equalization error. CONSTITUTION:A main line signal is directly supplied to an adder 6, the outputs of the adder 6 are simultaneously supplied to the two comparators, and their amplitudes are binarized. When the outputs of a comparator 7 have no errors, they correspond to original data. On the other hand, a comparator 8 binarizes the outputs of the adder 6 by adding a threshold, which is higher or lower than that of the comparator 7, to the reference level. The equalization error is calculated with the use of a computer 10. According to a result, the value of a DA converter 11 is increased/decreased, and the threshold of the comparator 8 is controlled so as to be a necessary amplitude value. Thus without affecting the main line signal by a gain regulating circuit at all, only the equalization error generated in the recording/reproducing system can be extremely accurately detected.
