Title: Jet pump
Inventor: MOCHIZUKI TAKUO
IPC: F04F5/46
Filed: 1990-02-07
Abstract: PURPOSE:To make a jet pump compact as a whole by injecting a high pressure fluid pressurized by a fluid pressurizer from injection nozzles, and interposing a suction port between a discharge pipe disposed forward of the injection nozzles and the injection nozzles. CONSTITUTION:When a high pressure fluid pressurized by a fluid pressurizer 7 is injected from a plurality of injection ports of an injection nozzle 6 toward a discharge pipe 5, respective jet flows are gradually expanded at almost the same expansion angle. Even if the power of the jet flows is high and the expansion angle is small, the expansion angles of the jet flows injected from the plurality of injection nozzles 6 are added together so that a distance from the injection nozzles 6 to a position where the jet flows are fully expanded inside the discharge pipe 5 is remarkably shortened. Therefore, a jet pump can be made compact as a whole with the short discharge pipe 5.

IPC: H03F3/189
Filed: 1990-02-07
Abstract: PURPOSE:To utilize a non-linear amplifier with high efficiency by feeding back the output of the first amplifier to the input side of the second amplifier, and feeding back the output of the second amplifier to the input side of the first amplifier. CONSTITUTION:The outputs of amplifiers 1 and 2 are respectively fed back by a feedback loop whose gain is '1' through attenuators 5 and 6 to the input sides of the others, then oscillation occurs. This oscillation is made stable in a certain state. In the stable oscillation state, the output of an adder 3 is an output synthesizing the vectors of an input wave X and an orthogonal wave Y, and this synthesized output comes to a constant amplitude wave A=X+Y equipped with the constant amplitude. Similarly, the output of an adder 4 is an output synthesizing the vectors of the input wave X and an orthogonal wave -Y and comes to a constant amplitude wave B=X-Y equipped with the constant amplitude. Therefore, for signals to be inputted to the amplifiers 1 and 2, the envelopes are the constant amplitude waves A and B equipped with the constant amplitude. Thus, it is not necessary to use linear amplifiers for the amplifiers 1 and 2, and the non-linear amplifier with high efficiency such as a C-level amplifier can be utilized.

Title: Thermal magnetic recording medium
Inventor: TAKAHASHI YUUICHI
IPC: G03G19/00
Filed: 1984-02-16
Abstract: PURPOSE:To control a direction of a heat conduction, so that an impressed range is not varied by a variation of an impressed heat quantity, by dividing a recording layer of a recording medium into minute blocks by a material of a low heat conductivity. CONSTITUTION:A recording medium 1 has a recording layer 4 divided into minute blocks by a wall 3 of a low heat conductivity on a base layer 2. The wall 3 of a low heat conductivity is formed, for instance, by embedding a resin whose heat conductivity is low between the recording layer and the recording layer. Since this wall exists, heat impressed to the recording layer 4 is not transmitted to other adjacent magnetic recording layer, and mainly conducts to only a direction of the base layer 2. Therefore, as for the part to which heat of the recording layer 4 is impressed its temperature rises efficiently up to a curie point, it is magnetized by a small magnetic field when it is cooled, and a magnetic latent image 5 is formed.
