Title: Floating magnetic head
Inventor: MATSUZAKI MIKIO
IPC: G11B5/31
Filed: 1989-10-12
Abstract: PURPOSE:To reduce the extent of floating to prevent remaining of powdery scrap or the like and to extend a taking-out electrode forming area by forming rails into steps to have steps in both edges in the breadthwise direction orthogonal to the flow of air and have higher faces in center parts, and providing such a depth that higher faces go to dynamic pressure generating faces, and forming the face between rails in one plane. CONSTITUTION:Plural rails projecting to the side of a slider surface facing a medium are provided in the direction of the flow of air apart from each other in the breadthwise direction orthogonal to the direction of the flow of air. A magnetic head element 2 is provided on one end face in the air flow direction of at least one of rails 11 and 12. Rails are formed to have steps in both edges in the breadthwise direction and have higher faces in center part, and higher faces of steps 111, 112, 121, and 122 have such depth that they are practically dynamic pressure generating faces, and the face between rails is practically one plane as the whole. Thus, areas of dynamic pressure generating faces are reduced to the extent of floating, and powdery scrap, sludge, or the like does not remain between rails, and the taking-out electrode forming area is extended to increase the number of degrees of freedom of design.

Title: Method for controlling charging and discharging of combined battery
Inventor: KONNO YOSHITO
IPC: H02J7/02
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To reduce the fluctuation of depths of discharge among the single batteries of a combined battery and to improve the cycle lives of the single batteries by connecting a capacitor in parallel with the batteries. SOLUTION: A capacitor C is connected in parallel with a combined battery constituted by connecting six single batteries A1-A6 in series. The capacitor C is of an aluminum electrolytic type and has a capacitance of 100 μF, In addition, the capacitor C is successively connected to the positive- and negative- electrode terminals of each single battery A1-A6. When the combined battery is constituted in such a way, the voltage fluctuation among the single batteries A1-A6 is reduced to 0.015-2.75 V after second leveling is performed by connecting the capacitor C to the batteries A1-A6.  When the leveling is continuously made three times, the voltage of each single battery can be adjusted to 2.745±0.005 V at which the charging and discharging cycles of the single batteries are not hindered substantially, Therefore, the discharging capacity of the combined battery can be secured and the cycle life of each single battery can be improved without receiving any restriction from the single battery having the minimum charged amount.

IPC: H03M1/10
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a check method for a D/A converter using a digital tester that can shorten the check time. SOLUTION: A device 1 is checked by means of a standard device 2 and a comparator 6 in addition to a digital tester 8.

The comparator 6 outputs the difference voltage between both signals 4 and 5 to the tester 8 as an output signal 7. The tester 8 decides a 'defective' state and a 'non-defective' state when the signal 7 of the comparator 6 exceeds and included in a prescribed range respectively. Then the tester 8 identifies that the device 1 is non-defective when all signals 3 corresponding to each input enable value are decided non-defective in response to the number of bits of the device 1.

Title: Numerically controlled automatic lathe
Inventor: SUGIMOTO KENJI
IPC: B23B7/06
Filed: 1985-11-26
Abstract: PURPOSE:To decrease a number of control axes while to improve productivity, by performing a numerical control (NC) of tools on the first and second tool rests while cutting simultaneously by the tools on the both tool rests. CONSTITUTION:The first tool rest 40 moves in an X1-axis direction being the direction approaching toward and separating from the center line of a main spindle. The second tool rest 52 moves in an X2-axis direction, being the direction approaching toward and separating from the center line of the main spindle, and a Y-axis direction being the direction crossing at a right angle with the X2-axis direction. Accordingly, while a tool on the tool rest 40 performs cutting, a tool on the tool rest 52, being selected approaching a work, can be placed in a standby condition, or the tools on the both tool rests can simultaneously perform cutting. Since the both tool rests are controlled only by a control of the three axes of X1, X2 and Y, a small number of control axes are only required.

Title: Automatic response public line adaptor
Inventor: OHAMA TSUNEICHI
IPC: H04L13/00
Filed: 1984-12-19
Abstract: PURPOSE:To improve the operation efficiency in on-line of its own station and an opposite station by providing an affirmative or negative response function being a part of a protocol to a line adaptor and functioning it separately from an on-line program. CONSTITUTION:When a CA detects an incoming signal from an opposite station, the CA informs the incoming to a CPU by using an interruption signal. When the on-line program is in READY state, the incoming interruption is received. The program commands the line connection to the CA. On the other hand, a timer supervisory is attained from the said interruption to the line connection command and when no command is given during a prescribed time, the CA makes line connection to attain communication state. The CA applies sequentialy buffering to a memory in the CA for a transmitted TEXT from the opposite station. The response to the opposite station is attained by an ACK or an NAK. The line is disconnected by the EOT reception after the final TEXT and the preceding interruption is recorded again to the on-line program after line disconnection.

Title: Method and device for detecting forged currency
Inventor: FAN ZHIGANG
IPC: G06V10/32
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To accurately detect forged currency by the use of line detection. SOLUTION: A detector (microprocessor) is trained by the use of an example note such as a bill in an off line. In the training, at least one template is generated by recording an image pattern of the example note on a test pattern to be detected. An anchor line in the template is discriminated from an anchor line indicated in the test pattern. The template is rotated and shifted so that the anchor line is aligned to a long line to be detected in the test pattern before matching the template with the test pattern. The template is compared with the test pattern to judge whether the anchor line exists in the test pattern or not. Consequently forged currency or the like can be detected.
