Filed: 1985-03-20
Abstract: PURPOSE:To improve the performance of bonding by an ultrasonic contact bonding method, by making Al of high purity contain iron (Fe) of 0.01wt%-0.009wt%. CONSTITUTION:Iron (Fe) is used for enhancing the corrosion resistance of Al at high temperature and under high pressure, and no effect is produced for improving the corrosion resistance when the content of iron is less than 0.001wt%, while education is so increased as to cause disconnection when it exceeds 0.009wt%.

In the case when nickel (Ni) is contained in Al together with iron (Fe), no effect is produced for improvement in the corrosion resistance when the content of iron (Fe) is less than 0.001wt%, while no improvement in the strength at high temperature is brought about when the content of nickel (Ni) is less than 0.001wt%. When the total contents of iron and nickel exceed 0.01wt%, the purity is reduced and the deposition is increased, which causes disconnection.

Title: Refrigerating cycle control system
IPC: B60H1/32
Filed: 1992-03-17
Abstract: PURPOSE:To prevent early wear of an engagement clutch means by combining a friction transmitting mechanism with the engagement clutch means while downsizing and weight-reducing an electromagnetic clutch. CONSTITUTION:A compressor is constituted to be of variable capacity type. A pin 44 constituting an engagement clutch means 43 is supported by an armature which is integratedly rotated with a rotary shaft 17 of this compressor. A pin hole 50 is formed in a rotor 34 opposite thereto. When the compressor 2 is started, the capacity of the compressor (the driving torque) is reduced, and at the same time, the rotation of the compressor is started by making the magnetic attracting force of a magnet coil 32 smaller than the set value, thereby attracting the armature only, i.e., with the frictional transmission only. Around the time when the rotation of the compressor has been increased sufficiently, the pin 44 is also attracted and engaged with the pin hole 50 by energizing and controlling so that the magnetic attracting force of the magnetic coil 32 may be larger than the set value.

Abstract: PURPOSE:To form the title voltage impressing type optical element with refractive index distributions of various profiles in its transparent dielectric, by bringing a molten salt contg. a cation contributing to the refractive index distribution into contact with the transparent dielectric, and impressing a voltage by a specified method. CONSTITUTION:The molten salt 6 contg. a cation contributing to the refractive index distribution is brought into contact with the transparent dielectric 1, a voltage (an electric power source 4, an anode 3, a cathode 2, and the molten salt 5 on the cathode side) is impressed to generate an electric field in the dielectric 1, the cation is implanted into the dielectric 1 by the electric field effect, hence a refractive index distribution is formed in the dielectric 1, and a voltage impressing type optical element is formed. In that case, the voltage is impressed so that the electric field generated in the dielectric 1 is converged in the direction of one electrode or diverged. For example, the contact surface area of the molten salt 5 with the dielectric 1 is made smaller than that on the anode 3 side, hence the electric field is converged from the anode to the cathode when a voltage is impressed from the power source 4, the cation infiltrates into the dielectric 1 more rapidly and deeply at the center part, and a refractive index distribution 8 is obtained.

Title: Phase controlling circuit
Inventor: SHIMADA SADAHIRO
IPC: H02M1/08
Filed: 1981-04-17
Abstract: PURPOSE:To maintain a load current constant with respect to the variation in the voltage of a power source by rectifying the voltage of a power source, and supplying the rectified voltage to the gate circuit of an FET, thereby regulating the gate voltage. CONSTITUTION:The gate voltage of an FET 10 satisfies the condition of an equation, where I10 represents a current which flows through the FET10, I17 represents a current which flows through a resistor 12 from a transformer 17, R11 represents the resistance value of a variable resistor 11, and R12 represents the resistance value of the resistor 12. Thus, when the voltage of a power source 1 becomes high, the voltage of the transformer 17 rises, the current I17 increases, and the voltage VGS becomes high at the negative side, thereby decreasing the current which flows through the FET10. Accordingly, the charging current to the capacitor 5 decreases, causing a thyristor 3 to be delayed in conducting ON and the conducting angle of the load current of a motor 2 to become narrow. As a consequence, the power consumed at the load does not alter. Conversely, when the voltage decreases, the power can be maintained constant.
