Filed: 1985-02-14
Abstract: PURPOSE:To improve the separating performance, etc., between adjacent channels by forming a laminated unit with head elements divided into a group for an odd channel and that for an even channel and containing them in a common case through a shielding plate. CONSTITUTION:The head elements 12a-12h corresponding to eight tracks 11a-11h of a magnetic tape 10 are divided into two groups: one includes the odd channel head elements 12a, 12c, 12e and 12g and the other includes the even channel head elements 12b, 12d, 12f and 12h.

IPC: B23K9/12
Filed: 1984-02-20
Abstract: PURPOSE:To make a detecting part small-sized and light, and to execute a profiling control with a high accuracy by operating a signal from each comparator and moving up and down a position of a welding torch. CONSTITUTION:When welding arc 13 is separated from a lower side base metal groove edge 11, an angle made by the surface of a lower side base metal and a shadow 14 becomes small, and the shadow 14 goes down at the tip of a detector against the lower side base metal groove edge 11. On the other hand, the detector 1 moves upward together with a welding torch. In this case, in a state that a part of a lower side slit 4l projects to the upper part of the shadow 14, a light quantity detected by a photodetector 2l of the lower side increases, and an output voltage amplified by an amplifier 5l becomes higher than a reference voltage outputted from a reference voltage setting device 6l. From a lower side comparator 7l, a digital signal is outputted, a light quantity detected by a photodetector 2u of the upper side is not varied, and ''0'' of a digital signal is outputted from an upper side comparator 7u. These two signals are operated by an operational amplifier 8, and a descent signal is outputted. As a result, a welding torch 15, the detector 1 and a slide copper strap move downward.

Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To provide an optical recording and reproducing device capable of always correcting displacement of an objective lens due to its gravity even when the sensitivity of an optical disk is changed. SOLUTION: In order to make the amplitude of output of a tracking error signal after correcting a displacement amt. of the objective lens 3 by an offset correcting means 8 constant, variable gain amplifiers 10 and 18 are varied at the same ratio.

Consequently, even when the objective lens 3 used for tracking control is sagged on account of its displacement due to gravity, etc., this sagging can certainly be corrected.
