Title: Method of etching aluminum foil for electrolytic capacitor
Inventor: KOIKE ATSUSHI
IPC: H01G9/04
Filed: 1989-02-01
Abstract: PURPOSE:To enable an electrode foil to be etched both at a low frequency and a high frequency in the same process by using A.C. current having a waveform in which one cycle of high frequency and a half cycle of low frequency are repeated alternately. CONSTITUTION:An aluminum foil is dipped in an etching solution and A.C. current is applied to etch the surface of the foil. The A.C. current used for this purpose has a waveform in which a cycle of high frequency HF and a half cycle of low frequency LF are repeated alternately. Accordingly, one cycle of the frequency HF and a half cycle of the frequency LF act on the aluminum foil through the etching solution alternately and the electrode foil is etched thereby. The frequency LF is in a range from 7 to 20Hz and the frequency HF is in a range from 35 to 80Hz. Current density ratio of HF to LF is 0.3 or less. In this manner, the electrode foil is etched roughly at the frequency LF and the rough surface thereof is etched finely at the frequency HF. As a result, the etching magnitude can be increased by about 30% in comparison with the case where a constant frequency is used.

Title: Belt transmission device having automatic tension adjusting mechanism
Inventor: KAWAHARA HIDEAKI
IPC: F16H7/16
Filed: 1989-01-31
Abstract: PURPOSE:To contrive transmission of large drive power decreasing a torque loss with balance of power improved, when the drive power is transmitted, by continuously decreasing an eccentric amount of the second pulley member from the first pulley member following an increase of the drive power of the first pulley member. CONSTITUTION:When a drive shaft 1 is placed in a loaded condition, drive power is transmitted from the first pulley member 4 to the second pulley member 7 through a ball 16 in the side of a driven pulley 17 for an axial center O1 of the member 4 further in the part of a belt tightened side. Consequently, the member 7 moves along a plane P, passing through axial centers O1, O2 of the members 4, 7, to the tightened side of a timing belt B, distributing tension by the moving in a fixed proportion to the belt B in its tightened and loosened sides. As the result, durability can be improved by effectively suppressing a skip phenomenon of the belt B. While because ball guide holes 14, 15, engaged with the ball 16, are provided in both obverse and reverse of a drive pulley 3, balance of power in a thrust direction is improved when the drive power is transmitted from the member 4 to the member 7, and a torque loss can be decreased further enabling the transmittable drive power to be increased.

Filed: 1985-02-12
Abstract: PURPOSE:To measure an inter-electrode distance with good accuracy and to adjust adequately the inter-electrode distance in one-side electroplating by measuring the thickness of an electrode row and determining the inter-electrode distance from the value thereof. CONSTITUTION:The thickness of the electrode row is measured by a thickness measuring mechanism provided to a gripping means in the stage of gripping the electrode row by the gripping means. On the other hand, the distance (a) from an electrode support 2 to a pass line 5 is always measured. The inter- electrode distance (c) is determined from the distance (a) and the electrode thickness (b) measured in the above-mentioned manner. The distance (c) and a reference inter-electrode distance are compared and the controlled variable, i.e., the distance to raise the electrode support 2 is determined and the support 2 is so controlled as to raise the electrodes X by as much as the determined distance. The maintenance of the adequate inter-electrode distance is thus made possible at all times in one-side electroplating.

Title: Magnetic head
Inventor: KONDOU HISAO
IPC: G11B21/20
Filed: 1984-02-10
Abstract: PURPOSE:To prevent an off-track state at the core position of each head slider due to the temperature change and to attain the record/reproduction with high track density, by using a plastic material having a higher coefficient of heat expansion to an arm at the side where a gimbal is used than that of the arm material at the other side. CONSTITUTION:An off-track state can be avoided by securing the coincidence of heat displacement between a head slider 1 at the side of an arm 6 and another head slider at the side of an arm 7. Therefore the arm 6 uses a plastic material having a larger coefficient alphaC of heat expansion than the coefficient alphaB of the arm 7. For this purpose, the arm 7 usually uses a polycarbonate material containing glass. Thus the glass content rate of the arm 6 is reduced relatively less than the arm 7 by several - 20% to set the alphaC at a desired lever. Thus it is possible to reduce an off-track state of a head slider down a level less than several micron compared with a floppy medium. This secures the working margin of a floppy disk having high track density, i.e., an effect of high reliability with a magnetic head.

Title: Gate drive device for magnetic bubble memory
Inventor: NAGAI HAJIME
IPC: G11C11/14
Filed: 1983-02-16
Abstract: PURPOSE:To guarantee nonvolatility of information by connecting the 1st electric power supply to a terminal of a gate conductor, connecting a transistor (TR) between the other terminal of the 2nd power supply and providing a relay in parallel with the gate conductor and its driving pulse source. CONSTITUTION:When a voltage of a power supply V is within a specified range, a power supply convincing signal 7 is applied to a pulse source 6 and a control current is applied to a relay 5. In driving a TR2 by applying a current to a base, the TR2 flows a desired current pulse to the gate conductor 1. If the voltage of the power supply V is not a specified value and no power supply convincing signal 7 is applied to the pulse source 6, that is, at the application or disconnection of the power supply V, since the pulse source 6 does not apply a control current to the relay 5, its contact 5a is closed so as to short-circuit across the gate conductor 1. As a result, no current charging/discharging a floating capacitance 4 flows to the gate conductor 1 but flows to the contact 5a of the relay 5. Thus, the generation of bubble error due to leakage current of a bubble memory chip to the gate conductor 1 is prevented in advance.

Title: Control channel contention control method
Inventor: MAEKAWA YOSHITO
IPC: H04L12/02
Filed: 1991-01-24
Abstract: PURPOSE:To prevent mis-detection due to occurrence of contention caused by a bit error of a received echo bit by discriminating the execution of transmission stop of a control channel in response to a counted bit number. CONSTITUTION:The method is provided with a buffer 1 to store tentatively a sent D-bit and a comparator 2 comparing the transmission D-bit stored in the buffer 1 with a received reception E-bit through a line which outputs 0 in the case of coincidence and 1 in the case of dissidence.
