Title: Signal recording method and recorded medium processor using the method
Inventor: OKADA SHUNJI
IPC: G11B7/24085
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To obtain a signal recording method and a recorded medium processor capable of obtaining reproduced signals having little noise and also capable of recording signals at a high density. SOLUTION: Video tracks M, N are formed by recording a signal while using plural magnetic heads whose azimuth angles are different from each other. In the case of overwriting a signal from the position of a track M(n), a track Q(1) is formed by recording the signal with a head whose azimuth angle is different from that of the track M(n). Thereafter, tracks P, Q are formed by successively changing heads. After the track Q(1) and succeeding tracks, the residual magnetic flux of a signal which is already recorded in a position deeper than that of the overwrite signal is formed. At this time, since the azimuth angles of the overwrite signal and the already recorded signal are different from each other, when the signal of tracks P, Q is read out, the noise of the already recorded signal is reduced by an azimuth loss and also signals can be recorded at a high density.

Title: Furnace plasma light emission analyzer
Inventor: UMEMOTO MASAO
IPC: G01N21/73
Filed: 1985-10-21
Abstract: PURPOSE:To perform highly accurate analysis, by displacing a plasma-energy projecting position accompanied by the movement of a movable carbon rod having a part to be checked for a sample to be analyzed, and processing the plasma lighting signal of the sample by a wavelength modulating means and the like. CONSTITUTION:A carbon rod 1 has a part to be checked 11 for positioning a sample to be analyzed. The rod 1 is formed so that it can be moved in the up and down directions shown by arrows A and B with respect to the generating position of a plasma 2. At the time of analysis, the tip of the part to be checked 11 is positioned at a symbol 12. The part 1 is started at this position upward. The position, where the sample receives the energy of the plasma 2, is displaced in this constitution. The carbon rod 1 is moved up and down by way of a flexible tube 3. Since the entire sample receives the plasma energy in this structure, loss is not yielded due to less atomization efficiency. Therefore, sufficient analysis can be conducted even if the amount of the sample is small. Sensitivity is high, and sufficiently accurate analysis value is obtained.

Title: Fluid pressure automatic regulating device
Inventor: WATANABE HITOSHI
IPC: G05D16/06
Filed: 1989-09-11
Abstract: PURPOSE:To miniaturize a passage system by providing a diaphragm deformed by fluid pressure, a spring energizing a movable shaft, and a means driving against the spring, and conducting adjustment of fluid pressure and cut of fluid with one device. CONSTITUTION:When electrification is stopped, a plunger 23 is pushed by a spring 14 to raise a movable shaft 5, and a valve body 7 closes a connecting passage 4. When electrification is conducted, an excitation driving force pushes down the plunger 23 by the force of an excess over the energizing force of the spring 14. When the excess is small, the displacement of the movable shaft 5 is small, and the opening of the connecting passage 4 is small, so that the fluid pressure in a low pressure chamber 3 is low, and the force pushing up the movable shaft 5 of the diaphragm 8 is also small. Thus, the movable shaft 5 is pushed down by the force of the excess and rested in a position where this push-down force and the pressing force of the diaphragm 8 are balanced. When the excess is large, the reversed course is followed, and the opening of the connecting passage 4 is increased, but rested in a fixed increased position, and thus, the liquid pressure is adjusted correspondingly to the electrification quantity.
