Title: Floating type melting device with molten metal discharged from bottom hole
Inventor: TADANO HIDEAKI
IPC: F27B14/14
Filed: 1994-03-14
Abstract: PURPOSE:To enlarge the buoyancy for allowing a molten metal in a crucible to be afloat without increase of the current. CONSTITUTION:A crucible 1 is provided with a molten metal discharge pipe 13 through which a molten metal 5 in the crucible 1 is discharged, and a projection 16 protrusive inward is formed in the coupling part of the pipe 13 with the bottom of the crucible 1 by enlarging the inside diameter of the molten metal discharge pipe 13 except the coupling part. Because the eddy current generated at the inner surface of the pipe 13 by feeding a current to an induction coil 2 is concentrated on the projection 16, the buoyancy of the molten metal 5 generated by the electomagnetic force, which is generated by the interaction of the concentrated eddy current, with the eddy current at the undersurface of the molten metal 5, will increase.

Title: Method and device for measuring adhesion force of fine particle
Inventor: IIMURA HARUO
IPC: G01N15/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To make measurable an electrostatic adhesion force and a non- electrostatic adhesion force. SOLUTION: After a fine particle is allowed to adhere to a supporting substrate from a sample substrate where the fine particle is allowed to adhere by a centrifugation device, the fine particle on the supporting substrate is sucked from a suction nozzle 23 and is taken into a fine particle introduction part 24 of a fine particle suction device. When the fine particle is taken into the fine particle introduction part 24, the amount of electric charge of the fine particle is measured by an electrode 25.  By obtaining the amount of electric charge per fine particle from the number of fine particles adhering to the adhesion surface of the supporting substrate that is measured in advance and the amount of electric charge, the relationship between the amount of electric charge and the adhesion force is obtained and the electrostatic adhesion force and the nonstatic adhesion force can be obtained.

Title: Push-pull amplifying circuit
Inventor: SAKAI KAZUMASA
IPC: H03F3/30
Filed: 1979-04-06
Abstract: PURPOSE:To improve a distortion rate by preventing an output transistor from being cut off completely while it provides no amplification, by adding a fixed circuit to a B-class SEPP circuit. CONSTITUTION:To a B-class SEPP circuit, a series circuit of constant current circuit 25 consisting of TR20, diodes 21 and 22, etc., and diode 26 is connected between power supply +B and the base of output transistor TR1 in order to flow a base current to TR1. Between connection point G and output point H, another series circuit of variable resistance 33 and diodes 34 and 35 is further connected. Additionally, a similar circuit is connected to output TR2. As a result, while TRs 1 and 2 provide no amplification, i.e., at the time of no input or during the period of a positive or negative input signal, TRs 1 and 2 never turn OFF because of the application of a constant voltage. The distortion rate of the amplifying circuit can therefore be increased.

IPC: G06F9/46
Filed: 1989-02-22
Abstract: PURPOSE:To facilitate the introduction of an operating system OS even in such a computer system that applies frequently the interruption processes by incorporating an interruption processing protecting function into the OS. CONSTITUTION:An interruption process handler 7 which produces an external interruption is driven and a system call inhibiting system call is produced right before an inhibition sector 8 where an interruption due to a system call (software interruption) is not desired. Thus an OS turns on an inhibition flag 2. When the process of the sector 8 is over and an inhibition release system call 11 is produced, an interruption process protecting function part 1 of the OS turns off the flag 2 to connect all tasks so far connected to a system call queue part 3 to an active queue part 9 and carries out successively the stored system calls via a scheduler 4. As a result, the system call received from a task under an interruption process can be inhibited in an optional section under the control of the OS.
