Abstract: PURPOSE: To obtain high rigidity without any stepladder bar by providing the subject mechanism with one pair of compressing parts to unfold legs as a standing mechanism together with the one pair of pulling parts on respective foldable legs with an opposite T shape having a folding mechanism. CONSTITUTION: A bottom end of a leg 16 is pulled outwardly in order to separate from a table platform 10 when standing a table. Once the leg 16 is pushed in a standing position, a shaft arrives at ends of respective slots in respective pulling links 86a and 86b to maintain the pulling links 86a and 86b in a tensile state by setting of a final rocking position of the leg 16. By tensile power which acts on a shaft fixed to the compressing parts 100a and 100b at their ends, the compressing parts 100a and 100b become in their compressed states. The pulling links against the compressing parts 100a and 100b give remarkable rigidity to the standing table.  Furthermore, by arranging a screwing slot on two adjustable pressure supports 56a and 56b screwed within a leg top part 50 and by screwing between rocking projections, abrasion and relaxation accumulated in the table mechanism are avoided for a long period.

Title: Magnetic recording and reproducing device
Inventor: YAMAMOTO YOSHIHITO
IPC: G11B20/02
Filed: 1987-04-17
Abstract: PURPOSE:To effectively delete the disturbance signals without causing undesired deterioration of an original signal by using a disturbance signal detecting circuit and turning on and off the actuation of a disturbance signal deleting circuit. CONSTITUTION:The voice signal reproduced by a magnetic head 1 is amplified by a reproduction equalizer amplifier 2. The reproduction signal given from the amplifier 2 is sent to a disturbance signal detecting circuit 4. The circuit 4 detects the presence or absence of a disturbance signal contained in the voice signal and outputs the result of this detection in the logic signal. A changeover switch 3 is controlled by the logic output given from the circuit 4. The switch 3 is changed over to the lower side when the disturbance signal is contained in the reproduction signal so that the reproduction signal passes through a filter 5. While the switch 3 is changed over to the upper side when no disturbance signal is contained in the reproduction signal so that the reproduction signal is prevented from passing through the filter 5. Thus it is possible to avoid deterioration of the band of an original signal when no disturbance signal is contained.

Filed: 1980-07-14
Abstract: PURPOSE: To obtain molten joints having no pinholes, by performing pad welding with a welding rod having a specified composition and specified melting point into the space of a specified width between two materials to be welded.  
     CONSTITUTION: To perform welding on Pt-Au alloy material 1 and 1 containing Pt to be used for making glass-melting crucible as the main constituent, a space of 0.1W1mm is installed between the end of both the materials 1 and 1. A welding rod composed of an alloy containing Pt and/or Pd of ≥80w/o and whose melting point is not more tham 100°C higher than that of the material 1, is pad-welded into the space so that the metal of welding rod flow into the space. In this case, when the above-mentioned space is less than the smallest limit, the material 1 melts completely and a number of pinholes is produced in the welded part, and, when it is larger than the upper limit, many pinholes are produced because the boundary part between the welded part and the parent material is cooled quickly. Moreover, the limitation of the composition and melting point of the welding rod is to give a strength which can stand even for ≥1,000°C glass melting temperature to the pad- welded part and to eliminate occurrences of oxide films, and also to improve the workability. It is also contrived that the welded part may be solidified before the parent material is solidified.
