Title: Compressor structure for turbocharger
Inventor: OKANO HIROSHI
IPC: F04D29/62
Filed: 1980-04-01
Abstract: PURPOSE: To improve efficiency of a compressor in such a way that air flow speed energy is effectively converted into pressure by forming into a smooth concave curved wall the junction face between one side of ring-shaped wall constituting a diffuser and the inner wall outside an air discharge chamber.  
     CONSTITUTION: Air sucked by rotary movement of an impeller 14 is compressed in the impeller 14 itself, speed energy is given, and then the air is flown into a vaneless diffuser 16. And, though the speed of air flow rushing out of the diffuser 16 is rather fast, energy possessed by the air flow is not wasted as the air flow gradually deviates its flow path along a concave curved wall 47 which is formed to smoothly join the junction part between one part of the first ring-shaped wall 45 to form a diffuser 16 and the inner wall outside an air discharge chamber 17. This serves to effectively convert the speed energy of air flow into pressure, and to improve efficiency of a compressor.

Title: Agc circuit
Inventor: NAGASE HIROYUKI
IPC: H03G3/10
Filed: 1984-03-05
Abstract: PURPOSE:To allow the AGC action to function more greatly with a simple constitution by connecting a transistor (TR) for AGC between the earth and the connection point between a resistance and a diode. CONSTITUTION:When an AGC voltage is impressed to a control terminal a3, TR2 is controlled to change the voltage between the collector and the emitter. Consequently, the DC current flowed from a power source +B to a resistance R1 is changed to change the voltage drop of the resistance R1. As the result, the voltage impressed to the drain of a field effective TR1 for amplification through a diode D is changed, and its degree of amplification is changed. The saturation voltage of the TR1 is absorbed completely by the diode D, and the field effect TR for amplification is turned off completely. Consequently, the AGC effect is allowed to function more greatly and practically.

Title: Method for dissolving polyvinyl ketal in water
Inventor: NAKAMURA HISAFUMI
IPC: C08F16/34
Filed: 1985-03-01
Abstract: PURPOSE:To enable the dissolution of a polyvinyl ketal in water without causing the deketalization, by dissolving a polyvinyl ketal having a specific ketalization degree in neutral or alkaline water at a low temperature. CONSTITUTION:A polyvinyl ketal having a ketalization degree of 8-60(mol)% is dissolved in neutral or alkaline water at <30 deg.C. A resin having a ketalization degree of 8-25% is dissolved at <30 deg.C, and the one having the ketalization degree of 15-60% is dissolved at 0 deg.C. EFFECT:The dissolution of polyvinyl ketal is caused by the formation of an ice-like structure by the hydrophobic ketal group introduced into polyvinyl alcohol and water and when the temperature is increased, the ice-like structure is destructed to cause the aggregation of the molecules and the clouding of the solution. When the ketalization degree of the polymer is high, the amount of hydration is decreased by the decrease in the hydrophilic OH group, and accordingly, slight destruction of the ice-like structure causes the clouding of the solution and the polymer is insoluble in water at a high temperature.
