Thus, the left and right sides of the conductor 20 become a pair of electrodes 21b. The thickness of the film 21a becomes larger than that of the electrode 21b by the effect of the anodic formation. A resistor 30 is formed on the film 21 and electrode 21b. The head thus obtained serves to efficiently transfer the heat to the recording sheet, the applied electric power can be reduced, and irregular thickness can almost be eliminated. Therefore, high printing quality can be obtained.

Abstract: PURPOSE:To easily and accurately estimate the position of the boundary surfaces of horizontal strata of soil by extracting a curve high in correlation as the reflected wave from the boundary surfaces of horizontal strata of soil and extracting the calculated change point of a section dielectric constant. CONSTITUTION:A pulse wave having wide-band frequency is generated from a pulse generator 1 to be transmitted to a transmission antenna 2.

Next, the received reflected waves are sampled and only inflection points are extracted by an extraction circuit 4. The extracted inflection points are constituted as a plurality of point groups by an operation part 5 and the change point of a section dielectric constant is determined as the boundary surfaces of the horizontal strata of soil to be displayed on a dummy cross section display part 6.
Patent JP-H01264277-A (JP)
Title: Power switch
Inventor: SOMA HISASHI
IPC: H01L39/14
Filed: 1988-04-15
Abstract: PURPOSE:To obtain a circuit breaker which is more simple in construction, by using a superconductor which is movable to a switching place of a circuit. CONSTITUTION:When an abnormality takes place and an overcurrent yields in an electric circuit or a load apparatus, the heating value of heating resistance 10 which is provided in the electric circuit by approaching a superconductor 1 increases and then, the temperature of the superconductor 1 rises. When its temperature exceeds a critical temperature, the superconductor 1 makes a transition from a superconducting state to a normal conducting one. Further, even when a large current exceeding a critical current density flows in the superconductor 1 because of a short circuit trouble and the like, its conductor is transited to the normal conducting state in the same way. If transited to the normal conducting state, the repulsive force between the superconductor 1 and a permanent magnet 2 disappears and only the restoring force of a spring 4 acts upon the superconductor 1. As a result, the superconductor 1 moves in the left direction and is tripped from contact points 3. Then, the current is cut off and a breaking indication 6 comes out at once.

Title: Sheet clamp device
Inventor: UMEZAWA MICHIO
IPC: B41F7/02
Filed: 1979-07-19
Abstract: PURPOSE:To prevent a sheet from being loosened with a simple construction, by utilizing the centrifugal force acted upon a weight according to the rotating motion of a drum when pulling the rear end of the sheet. CONSTITUTION:A drum 2 is so arranged that its rotational speed increases when a retaining roller 22 drops down into a sunk hollow part 20 to support the rear end part of a sheet. If the drum 2 becomes rotating at a high speed, the centrifugal force acted upon a weight 35 overcomes the tension of a spring 39 to shift the weight 35 to a position as shown by a chain line. The shifting motion of said weight causes a tension roller 32 to make a turning motion clockwise through a lever 34. Accordingly, a sheet S is tightened by the turning motion of the tension roller 32 while being put between the retaining roller 22 and the tension roller 32, thus to eliminate the loosening of a sheet during the rotating motion of the drum 2.
