Title: Intermittent driving circuit
Inventor: TABUCHI JUNICHIRO
IPC: G11B15/467
Filed: 1987-08-05
Abstract: PURPOSE:To prevent horizontal swinging from being generated by reducing a difference between the change of speed in a cylinder motor, by lowering a loop gain for a prescribed period after starting up a capstan motor. CONSTITUTION:The start up of a tape is performed setting the edge of a head switching signal as reference, and a start up pulse C is generated based on the edge on one side of the head switching signal. An analog switch 7 is turned ON in the period of a pulse C set at an H level, and a source voltage is impressed on the servo input of a capstan motor driving circuit. Synchronizing with the above start up, a cylinder motor acceleration pulse A is generated, and the rotating speed of the cylinder motor is increased. Also, a capstan motor loop gain lowering pulse B is generated synchronizing with the pulse C. In the period which the pulse B is set at the H level, an analog switch 8 is turned on, and an input voltage at the inversion input terminal of an amplifier 6 is increased, then, the loop gain is lowered. In such a way, it is possible to prevent the horizontal swinging from being generated by reducing the difference between the change of the speed of the cylinder motor.

Title: Pattern forming method
Inventor: IWATATE KAZUMI
IPC: H01L21/027
Filed: 1986-08-21
Abstract: PURPOSE:To form the pattern having the width almost equal to that of the electron beam irradiation region to be used for formation of a latent image in the case of the pattern having a wide width, and also having the side face which is nearly vertical by a method wherein a latent image having a wide pattern is formed by the irradiation of the electron beam of low acceleration voltage, and another latent image having a narrow pattern is formed by projecting the electron beam of high acceleration voltage. CONSTITUTION:A latent image 1B having a wide pattern is formed by projecting an electron beam of low acceleration voltage. Consequently, even when energy is accumulated on the outside of the irradiation region of an electron beam sensitive layer 2, the extend of the amount of said accumulation is small, and as the range of said accumulation is small because the flying distance of scattering of reaction electrons is short in accordance with the low acceleration voltage of the electron beam. Also, a latent image 3A having a narrow pattern is formed by the irradiation of the electron beam of high acceleration voltage. As a result, even when energy is accumulated on the outside of the electron beam sensitive layer 2 from the electron beam irradiation region of the layer 2, the amount of said accumulation is small in proportion to the narrow width of the narrow-pattern. As a result, the pattern 4A with a narrow-pattern and the pattern 4B with a wide pattern can be formed.

Filed: 1986-08-22
Abstract: PURPOSE:To carry out favorable gain control where DC potential fluctuations are stationary and a dynamic range does not show a decrease by forming a well region on a SOI substrate and forming gate regions on the well through an insulation layer and controlling an electric field between the well region and the gate regions. CONSTITUTION:A well 2 is formed on a substrate 1 and an insulator 3 is formed on the well 2 and then a MOS region including gates 7a-7b is formed on the insulator 3. Once a voltage between the well region 2 and gate regions 7a and 7b is controlled, a longitudinal electric field of each MOS transistor channel between the above well region and the gate regions varies and the mobility also varies to control gm of each MOS transistor. Thus a gain of output signals is controlled by controlling gm of each transistor.

Title: Bonding method of flip chip
Inventor: HAJI HIROSHI
IPC: H01L21/60
Filed: 1990-07-25
Abstract: PURPOSE:To contrive large cost down by applying copper paste to copper bumps, mounting the copper bumps on copper patterns, and bonding the copper bumps to the copper patterns by heat treatment in an unoxidizing gas atmosphere. CONSTITUTION:Copper paste 4 is applied to the lower faces of copper bumps 3 with a dipper. Copper patterns 6 are formed on the upper face of a substrate 5. Because the copper paste 4 and the copper patterns 6 are made of the same material and bonded well, the patterns 6 are not plated with gold. A flip chip P is held by a nozzle 7 and the copper bumps 3 are mounted on the copper patterns 6. The substrate 5 is sent to a reflow apparatus and heat-treated to thermally harden the copper paste 4 and bond the copper bumps 3 to the copper patterns 6. This treatment is performed in a reducing or unoxidizing gas atmosphere because copper is oxidized and liable to deteriorate when heated.

Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a method which eliminates the necessity to use an extracting solvent or a molten salt and can reduce the yield of secondary wastes in the separation of various elements from high-level radioactive wastes. SOLUTION: High-level radioactive wastes and glass materials are poured into a melting furnace 1 equipped with a pair of electrodes 2, and alternating current is passed to mix and melt the wastes and the materials by heating them directly through energization. Thereafter, the mixed melt is taken out from the melting furnace 1 and is cooled to make vitrified solids. On this occasion, direct current is passed in the mixed melt in the melting furnace 1 to electrolyze it. Elements in the melt oxidized or reduced by the electrolysis are precipitated on the surface of the electrodes or in the melt. In the application of the direct current, the electrodes 2 for the melting furnace 1 may be used or other electrodes for the direct current may be inserted into the melt.

IPC: B22F9/08
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To produce a quenched and solidified powder having uniform quality by blowing gas jet against the molten metal stream flowed down from a raw material vessel, dividing the molten metal into molten drips and pouring the divided molten drips without spattering into cooling liquid layer flowed down while circulating along the inner peripheral surface of a cylindrical body for cooling. SOLUTION: The gas jet j1 for division directed to the cooling liquid layer 7 from a gas jet nozzle 4 and auxiliary gas jet j2 having small flowing speed from the reverse side to the gas jet j1 , are jetted, and the molten metal stream 5a is flowed down against the intersection part of both jets. The spattering upward of the molten drips divided with the gas jet j1 for division, is restrained with the auxiliary gas jet j2 and further, the auxiliary gas jet j2 becomes the integrated flow with the gas jet j1 for division and the molten drips are poured into the cooling liquid layer 7 while carried with this jet flow. By this method, the development of the spattered and floated molten drips is eliminated, and the metallic powder having small unevenness to the quality caused by the difference of cooling speed, can be produced.

Title: Tape feeding control circuit
Inventor: IMANISHI SADAO
IPC: G11B15/467
Filed: 1987-08-07
Abstract: PURPOSE:To prevent the occurrence of the disconnection of servo caused by the variation in DC component of a tracking error signal by separating a tracking error signal into a DC component and a tracking error signal component, amplifying the components with different amplification ratios, and inputting them in a mixing circuit. CONSTITUTION:The DC component of a tracking error signal ET flows only through a resistor R2 by the DC blocking capacitor of an amplification ration determining circuit 9, while tracking error signal component flows through both a resistor R1 and the resistor R2. Therefore, the amplification ratio is determined by the relation between the resistor R2 and a resistor R3, and thus the amplification ratio for the tracking error signal component is determined by the resistors R1-R3, and amplified by an amplification circuit 10. A speed servo circuit 8 generates a speed control signal SC so that the rotational speed of a tape feeding motor 7 is coincident with an instruction speed. The tracking error signal ET and the speed control signal SC are mixed with each other in a mixing circuit 5, and its 5 output is supplied to a driver 6 in order to control the rotational speed of the motor 7. As a result, the disconnection of servo caused by the variation in DC component can be prevented.
