Title: Spindle motor for magnetic disk device
Inventor: ISHIGAKI TATSUYA
IPC: G11B25/04
Filed: 1988-08-29
Abstract: PURPOSE:To prevent dust generated in the inside of a spindle motor from invading to the inside of a magnetic disk device by generating a gas flow advancing from the inside of the magnetic disk device to the outside of the magnetic disk device via the inside of the motor. CONSTITUTION:When the motor hub 30 of the spindle motor, a magnetic disk 42, and an impeller 60 start to rotate integrally, gas in a space between an impeller shroud 61 and hub shrouds 63a and 63b flows in the inside of the motor by the function of the rotary centrifugal force of an impeller fan 62 via notched parts 70a and 70b.

Meanwhile, gas pressure on the entry side for gas of the impeller 60 is decreased, and the gas flows in from the outside via a respiration filter 52 provided at a cover 51. In such a way, it is possible to prevent floating dust from flowing in a sealed space in the inside of the magnetic disk device.

Title: Production of high-purity copper
Inventor: KUROSAKA AKITO
IPC: C25C1/12
Filed: 1988-08-29
Abstract: PURPOSE:To enable the mass production of the high-purity copper having an excellent low-temp. softening characteristic at a lo cost by combining a crystal fractionation method by a difference in solubility of an aq. acidic copper sulfate soln. and a two-stage electrolytic refining method. CONSTITUTION:The aq. acidic copper sulfate soln. is prepd. by using electrolytic copper and a proper volume of water is evaporated therefrom to crystallize the copper sulfate. While the solubility of the anhydrous sulfate of the main metal impurity contained in the electrolytic copper in the water is about equal to or larger than the solubility of the copper sulfate, the solubility of the lead sulfate or silver sulfate is fairly small. However, the lead sulfate or silver sulfate has the large solubility in an aq. acidic soln. and the metal impurity of even the electrolytic copper which is available at a low price hardly exceeds 0.1wt.% and, therefore, the high-purity copper sulfate is crystallized without precipitating the sulfate of the metal impurity such as silver by the above-mentioned operation. Cations such as Ag<+>, Pd<2+>, Au<3+>, etc., having the smaller tendency to ionization than Cu<2+> are removed by electrolytic collection from the electrolyte obtd. by remelting the copper sulfate and thereafter, the cathode is set at a suitable electrode potential and only the Cu<2+> is electrolytically collected.

Operation state information of an REP2 itself detected by the REP2 is transmitted to communication lines 10 and 14 similarly, and that of an REP3 is transmitted to communication lines 11 and 13 similarly. An LTE4 transmits operation state information of the LTE4 itself gathered by an ACU8 to a communication line 12. Operation state information of individual REPs and LTEs are superposed onto bits added to the main signal in accordance with these procedures, thereby making it possible that any repeating installation monitors operation state information of all repeating installations on communication lines.

Title: Horizontal synchronizing signal processor and its processing method
Inventor: KITAMURA MASAHIRO
IPC: H04N3/227
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To suppress the variation of a horizontal position even if oscillation frequency setting voltage fluctuates within a pull-in range. SOLUTION: When oscillation frequency setting voltage 9 (VF/V) is within a pull-in range, the oscillation frequency of a current control oscillation circuit 12 is synchronized with the frequency of a horizontal synchronizing signal 1, and therefore the output current of an addition circuit 11 is proportional to the frequency of the horizontal synchronizing input signal 1. The output current of the addition circuit 11 is smoothed by a low pass filter 16 and it is set to be slower than the loop response of phase comparison. The output current of the low pass filter 16 is supplied to a delay circuit 2, a pulse generation circuit 3 and a delay circuit 8.  Thus, the delay time of the delay circuit 2, the pulse width of the pulse signal of the pulse generation circuit 3 and the delay time of the delay circuit 8 do not fluctuate since the current is proportional to the frequency of the horizontal synchronizing input signal 1. Then, the variation of a horizontal position can be suppressed even if oscillation frequency setting voltage 9 (VF/V) fluctuates in the pull-in range.

Title: Ferrite core and manufacture thereof
Inventor: SUZUKI JUNICHI
IPC: H01F3/08
Filed: 1988-08-26
Abstract: PURPOSE:To markedly reduce the time required for arrangement, and to make it possible to eliminate the adhesion between the blank materials adjacently positioned after a sintering treatment has been conducted by a method wherein projections are formed on one surface of the material, and a gap is formed between adjacent blank materials when they are arranged on a sintering plate. CONSTITUTION:When blank materials 11 of a square pole-like I-type ferrite core are pressed, projections 12 are provided on one surface of the materials 11. The above- mentioned materials 11 are arranged on a fireproof sintering plate 13, and at that time, the materials 11 are arranged in such a manner that their projections are brought to come in contact with the surface of the other materials 11 having no projection. The arrangement-finished sintering plate 13 is put in a sintering furnace, and after it has been sintered, it is taken out. The projections on the sintered materials 11 are removed by conducting a polishing process, and a finished ferrite core is obtained. As a result, the required gap is formed between adjacent materials, and most of the adhesion of the materials after sintering can be prevented. If, however, the materials 11 are adhered, they can be separated easily, because their contact area is small. Also, as the space between the materials 11 is set uniformly by the projections when they are arranged, the time required for their arrangement can be reduced remarkable.

Title: Resetting circuit
Inventor: KINOSHITA TOSHIJI
IPC: H03K17/22
Filed: 1981-12-29
Abstract: PURPOSE:To prevent erroneous control of a control circuit by sending out a reset signal to the control circuit when the output level of an oscillating circuit corresponding to a power voltage is less than a prescribed value. CONSTITUTION:When a telephone set is put off the hook, the power voltage VDD of a power circuit 6 increases with time. The oscillating circuit 8 applied with said power voltage generates an oscillation output which increases in amplitude according to the increase in the power voltage. This oscillation output is converted by a converting circuit 9 into a DC voltage, which is supplied to a deciding circuit 10 sends out the reset signal to the control circuit 7 when the DC voltage from the converting circuit 9 is lower than the prescribed value. Thus, when the power voltage is lower than the operation securing voltage of the control circuit, the control circuit is reset, so erroneous control of the control circuit is prevented.

Title: Sheet material feeding device
Inventor: AOKI TOMOYA
IPC: B65H3/52
Filed: 1988-08-26
Abstract: PURPOSE:To perform stable sheet feeding by forming a pressing member by which pressure is given at variable pressing angles to a sheet feeding direction. CONSTITUTION:A separation member 2 is supported by a moving member 10 which is rotated at a fulcrum of a moving fulcrum 4 from a lower direction between a pulley 7 and a pulley 9, and is pressed by a pressing member 3 in a direction of a feeding member 1. When a drive shaft 6 is rotated, a sheet material 12 is carried from a sheet feeding cassette 11 to a position sandwiched between the feeding member 1 and the separation member 2. If a thick sheet material is used, having it tilted to the right when the point of the sheet material is abutted on the separation member, the separation member 2 is pushed down by the component force 16 of the carrier force 15, and the distance between the carrier member 1 and the separation member 2 is kept appropriate, for the sheet material 12 to be separated stably. If a thin sheet material is used, by tilting it to the left, a separation member 5 is pushed up by means of the component force 17 of the carrier force 15, and with the expanded frictional force between the sheet material 12 and the separation member 2, stable separation can be performed without duplicate feeding.
