Title: Magnetic head support mechanism
Inventor: NAKAI AKIRA
IPC: G11B5/60
Filed: 1985-01-30
Abstract: PURPOSE:To prevent the lowering in printing quality and the damage of a magnetic medium by always holding a constant air gap, by contacting the roller attached to a multihead support member through a leaf spring with the magnetic medium and measuring the strain quantity or load applied to the leaf spring and moving a multihead to a direction negating the difference with a reference value. CONSTITUTION:Now, when a multihead support member 13 is moved to the direction shown by an arrow X by a drive system 18, rollers 14, 14' are contacted with a magnetic medium 11. At this time, the air gap between the magnetic medium 11 and a multihead 12 is set to an initial gap delta. When the multihead support member 13 is further moved to the direction X, the spring part of roller support metal fittings 15, 15' are bent and the air gap comes to a set gap delta1. In this case, because the relation between the strain measured values by the strain gauges 16, 16' adhered to the roller support metal fittings 15, 15' and the air gaps is almost proportional relation, the variation in the air gaps can be measured if strain quantity is measured. Because strain quantity can be measured by voltage, feedback control can be performed by comparing the strain quantity with reference voltage corresponding to the set gap delta1.

Title: Forceps plug for endoscope
Inventor: AKIBA HARUO
IPC: A61B1/00
Filed: 1997-01-11
Abstract: PROBLEM TO BE SOLVED: To enable one type of forceps plug to deal with whatever types of treatment instrument and whatever diameters thereof and also reliable introduction performance and leakage preventive performance to be displayed. SOLUTION: This forceps plug for an endoscope is equipped with a wrapped part 25h which is elastically detachable from an introduction outlet in a blocking part on the inner face of the blocking part and an introduction hole 25m in the wrapped part 25h running through the wrapped part 25h. When a treatment instrument is of a small diameter like a cannulation tube, it is caused to advance into the interior of an endoscope by introducing the tube through the introduction hole 25m in the wrapped part 25h. On the other hand, when the treatment instrument is of a large diameter like a bioforceps, it is caused to bypass the introduction hole 25m in the wrapped part 25h to advance into the interior of the endoscope by bending a cantilever part 25k to be deformed without introducing the bioforceps through the introduction hole 25m.

Then the piezoelectric substrate where the metallic thin film formed with these material is heated up to a prescribed temperature at a velocity less than 600 deg.C/min. and held for a prescribed time. Then the substrate is returned into a room temperature at the same velocity and annealed in a vacuum atmosphere or an inactive atmosphere of N2, Ar and H2. The holding temperature is set at a level higher than the substrate temperature set for formation of the film and also lower than the Curie temperature of the substrate. As a result, the power resistance properties can be improved and the internal loss is reduced. Thus the lifetime of a surface acoustic wave element is increased.

Abstract: PURPOSE:To attain miniaturized high frequency variable attenuation circuit by connecting four PIN diodes as a bridge, giving a signal from one of diagonal points, extracting an output from the other point and connecting a DC power supply to the other diagonal points. CONSTITUTION:Since PIN diodes D1-D4 have equal DC and AC electric characteristics, the potential difference between points (a), (b) in terms of AC is zero and there is no problem even when a DC power supply whose impedance is,e.g., 10ohms is connected between the points (a), (b). The current flowing to the diodes D1, D2 and the current flowing to the diodes D3, D4 are the same in terms of DC and high frequency attenuation in forward/backward directions in giving a DC bias current to the diodes D1-D4 in forward polarity, then the AC resistance of the diodes D1-D4 is equal and the condition of the bridge is satisfied. As a result, no high frequency current flows to the DC power supply 20 and an accurate high frequency attenuation is given. The bias voltage by the power supply is varied to vary the high frequency attenuation.
