Title: Current source circuit
Inventor: OOMORI YOSHIYUKI
IPC: G05F3/24
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain the excellent current source circuit employing a MOS transistor(TR) that supplies a current nearly constant with respect to a change in a power supply voltage by providing specific power supply and the MOS TR. SOLUTION: A voltage division of a voltage at a voltage source terminal is given at a connecting point between resistors 6, 7. The voltage is given to a gate of a MOS TR 8 to obtain a current depending on the voltage at the terminal 3 at its drain. A current flowing to a resistor 2 is the sum of a current by a MOS TR 1 and a current from the TR 8. That is, the current supplied to the TR 1 is a current subtracting the current flowing to the TR 8 from the current flowing to the resistor 2. Then the resistance of resistors R1-R3, a gate width and a gate length of the TR 8 are selected so that a current fluctuation rate of the current flowing to the TR 1 by the voltage at the terminal 3 approaches zero. Thus, a current which is nearly constant independently of a change in the voltage source terminal voltage is supplied to a drain of the TR 8.

Title: Back spacing circuit for tape recorder
Inventor: KAWACHI TSUNEYOSHI
IPC: G11B15/20
Filed: 1990-02-28
Abstract: PURPOSE:To fix the length of a magnetic tape to be rewound even if its winding diameter is changed by measuring the pulse width of a pulse signal obtained at the time of reproducing operation and counting up the number of pulses based upon the pulse width to determine the rewinding operation time. CONSTITUTION:In the reproducing operation state, a pulse signal outputted from a pulse signal generating circuit 25 is inputted to a pulse width measuring circuit 24 and the pulse width P is measured. A user sets up the length of the magnetic tape to be rewound in a rewinding length setting circuit 19 as the time T required for reproducing operation by the 1st and 2nd time setting switches 20, 21. When the rewinding operation of the magnetic tape is started, a pulse number counting circuit 26 counts up the number of pulses outputted from the circuit 25, and when the number N of pulses satisfied an equation N=A(1/PXT) (A is a constant), the output signal of a rewinding output terminal 17 is inverted to the 'L' level and a tape recorder is turned to a stopped state. Thus, the length of the magnetic tape to be rewound is fixed even if the winding diameter of the tape is changed.

Then a photoresist layer 22 is removed. Then a metal is allowed to deposit on the entire surface of a member, to form a metal wiring layer 34 which fills a contact opening 24 and the trench 26. Then, a selective polishing process such as the CMP process is performed with the metal wiring layer 34 until the upper part surface of the insulating layer 22 is exposed. The CMP process is performed with a metal wiring layer 34 which fills the trench 25 while not performed with a part where the first and second barrier layers 28 and 30 are removed.

Title: Surface metallic finishing method for concrete or the like by electricity
Inventor: KANDA MAMORU
IPC: C04B41/69
Filed: 1980-04-15
Abstract: PURPOSE: To obtain the titled surface metallic finishing having good adhesiveness by hardening the mortar or concrete buried therein with wire netting or the like and performing electrolysis with the wire netting as cathode.  
     CONSTITUTION: Wire netting 6 is buried in a structure 5 of mortar or concrete and the structure is allowed to harden. This wire netting 6 as cathode and anode 3 consisting of plate or bar of metal are installed in electrolyte 2, and DC voltage is applied thereto. Then, DC current flows from the anode 3 to the wire netting 6 through the structure 5 which is microscopically porous, so that anode metal deposits on the surface of the structure 5. When the current supplying time increases, the current is difficult to flow and the metallic deposition decreases successively. If electrolytic treatment is carried out at a proper time with the metallic film deposited on the surface of the structure 5 as new cathode, the uniform metallic finish surface is obtained efficiently.
