Title: Electromechanical transducer for low frequency
Inventor: KAMEYAMA AKIRA
IPC: H04R17/08
Filed: 1984-03-19
Abstract: PURPOSE:To obtain a small and light-weight electromechanical transducer for low frequency which has high resistance to hydraulic pressure, by producing a coil-shaped oscillator with an electrostrictive material that produces distortions according to the voltage impressed. CONSTITUTION:An electrostrictive material is used to produce a coil-shaped oscillator 1, and upper and lower end parts of the oscillator 1 are fixed by fittings 2 as shown in the figure. The oscillator 1 produces a so-called lateral electrostrictive effect where the vibrating direction is orthogonal to the field direction of the electrostrictive material. Therefore the oscillator 1 produces distortions in its lengthwise direction when electric signals are impressed to the oscillator 1 via lead wires 3a and 3b. Then the oscillator 1 produces mechanical vibrations in its circumferential direction. Thus the mechanical resonance is produced with a frequency that causes a standing wave of a half wave over the entire coil length of the oscillator 1. The both ends of the oscillator 1 are fixed with fittings 2 and therefore the vibrations are damped. Then the circumferential vibrations of the oscillator 1 are converted into the vibrations of the radius direction. Thus a sound wave of a resonance frequency can be radiated in the radius direction. A wave echo sounder transducer device is obtained by covering the outer surface of the oscillator 1 by the rubber molding, etc. and has excellent underwater resistance to hydraulic pressure.

Title: Field effect transistor and its manufacture
Inventor: NODA TAKAO
IPC: H01L21/338
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To form a barrier against electron which flows from a Schottky contact layer into an ohmic contact layer by inserting a barrier layer whose power affinity is specific between a Schottky contact layer and an ohmic contact layer. SOLUTION: A barrier is formed against electron which flows from a Schottky contact layer 106 into an ohmic contact layer 108 by inserting a barrier layer (electron affinity of 0.1eV or more) 107 whose electron affinity is smaller than that of a Schottky contact layer 106 between the Schottky contact layer 106 and an ohmic contact layer 108. A difference of electron affinity appears as a conduction band discontinuity ΔEc when the hetero junction of the Scohttky contact layer 106 and the ohmic contact layer 108 is formed and functions as an obstacle against electron since the conduction band of a material of smaller electron affinity is upper, and a barrier against electron which flows in can be formed.

Title: Fuel injection control device for engine
Inventor: CHO RO
IPC: F02D41/04
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection control device for engines, capable of stopping a pilot injection of fuel to prevent the combustion of an engine from becoming unstable when a target pilot injection quantity is below a predeter mined injection quantity and is too little. SOLUTION: When a target pilot fuel injection quantity Qpt calculated by step 2 is judged to be short of a minimum stable injection quantity Qs which can be stably injected from an injector by comparison in step 4, a pilot injection quantity Qp is set to zero in step 9, and a full main injection mode in which full fuel injection quantity Qt is injected by main injection, is set. Thus, the pilot injection is not performed at the fuel injection quantity, which is short of the minimum stable fuel injection quantity Qs, and stable combustion becomes possible. The pilot injection mode is shifted with time hysteresis set in steps 5, 8, etc.

Title: Structure of heat exchanging fin
Inventor: GOTO KAZUHIKO
IPC: F28F13/10
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To improve heat exchanging function of fin members without enlarging heat dissipating areas of the fin members, by installing a vibrating equipment for vibrating the fin members. SOLUTION: When a rotating shaft 6 of a motor 5 is rotated, the motor 5 is vibrated by centrifugal force, since the rotating shaft 6 is connected with a position biased from the center of a weight 7. The vibration of the motor 5 is transmitted to a base member 3 via a connecting part 8, and vibrating type fins 2 are vibrated in the surface direction of the base member 3. As a result, pressure difference is generated on boundary layers between heat dissipating surfaces positioned in front of the moving direction of fins 4 and air. The air in the vicinity of the boundary layers turns to the state of turbulence, and contact amount of the heat dissipating surfaces of the fins 4 and air per unit time is increase, thereby promoting heat exchange of the fin members 4 and improving heat dissipating function without enlarging heat dissipating areas of many fin members 4.

Filed: 1989-03-06
Abstract: PURPOSE:To obtain a nickel-hydrogen battery which can reserve effective discharge and easily control the amount of the discharge capacity by adding a metal powder to a nickel hydroxide powder. CONSTITUTION:A nickel electrode active mass is prepared by adding >=1 of powders selected from compounds of divalent cobalt and a powder of a metal which can form a stable oxide or hydroxide in a potential range where the active mass-bearing nickel electrode is used in an aqueous alkali solution as a cathode of an alkali secondary battery to a nickel hydroxide powder. since the added metal powder is nothing to do with discharge reaction. The electric amount equivalent to the amount consumed for oxidation reaction of the metal powder in an initial charging process can be reserved as discharge capacity. As a result, a large amount of discharge reserve can freely be reserved by controlling the amount of added divalent cobalt compound and a metal powder. By this way, an active mass for a nickel electrode which can reserve effective discharge reserve and a nickel-hydrogen battery using the active mass are obtained.
