Patent JP-S6348478-A (JP)
Title: Electronic circuit
Inventor: TOKUSARI TERUO
IPC: G01R31/28
Filed: 1986-08-19
Abstract: PURPOSE:To reduce a measurement error by detecting the potential difference between two ground lines of a 1st circuit part which is small in power consumption and a 2nd circuit part which is large in power consumption and canceling the input or output signal of the 1st circuit by as much as the difference. CONSTITUTION:The ground terminals of a D/A converter 10 and an A/D converter 12 which constitute the circuit part with large power consumption are connected to a ground line 14. The ground line 16 of a constant voltage circuit 24 and a current-voltage converting circuit 26 which constitute the circuit part with small power consumption is separated physically from the ground line 14. The input of an operational amplifier 18 is connected to a terminal 20a so as to remove a measurement error between the ground-side terminal 20a of a load 20 and the ground 14 due to the voltage drop across a connection line 22. The uninverted input of the input-state operational amplifier 30 of the constant voltage circuit part 24 is coupled with the ground lines 14 and 16, so the potential difference between the ground lines 14 and 16 is canceled at this input stage to eliminate variation in the applied voltage of the load 20 and improve the measurement accuracy.

Title: Magnetic disc apparatus
Inventor: TOMATSU SHIGEO
IPC: G11B21/08
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic disc apparatus which loses no time in seek operation and is resistant to shocks when accessing a disc. SOLUTION: A strut 3 is set in the vicinity of discs 1a-1d and in parallel to a strut 2 as a rotary shaft. Arms 4a-4h are extended along front and rear faces of the discs 1a-1d between the struts 2 and 3. Heads H1-H6 are arranged at every position of arms 4a-4h to confront tracks T1-T6 formed in the front and rear faces of the discs 1a-1d. Since the heads H1-H6 are arranged correspondingly to the tracks T1-T6 of every disc face in pairs, a seek time to access the disc is eliminated. Moreover, since the heads H1-H6 are aligned on each arm 4a-4h and both ends of each arm 4a-4h are fixed, the apparatus is resistant to shocks when accessing the disc.

Title: Overwrite display device
Inventor: SHIINA MASAHIRO
IPC: G06T11/00
Filed: 1989-07-28
Abstract: PURPOSE:To surely discriminate character graph information by giving a shadow to the character graph information when the character graph information is displayed to a video display area in confusion with video information. CONSTITUTION:Video information 82 with high brightness is displayed in the inside of a frame 12 of a display screen 11 while using a black level part 81 without video information as a background, and character graph information 83 comprising a character '1' is displayed on a part of the video information 82. The brightness of the character graph information 83 is nearly the same as the brightness of the video information 82 substantially and the brightness is further improved by the action of a D/A converter circuit and the result is clearly distinguished from the video information 82 together with the shadow 84. Since shadow is given to the character graph information when the video information and the character graph information are overwritten, even when the brightness of the information where a character exists is high, the character or graph is easily identified.

IPC: H01M2/02
Filed: 1994-08-19
Abstract: PURPOSE: To enhance productivity and yield of a battery by attachably and detachably arranging a battery case guide and controlling so as to be separated by the excess load caused by a battery case supplied. CONSTITUTION: When a battery case 11 is normally fit to a battery case fitting part 6 of a battery case feeding dial 5, since a battery case guide 10 and the battery case 11 are kept at constant intervals, overload does not produce between them. That is, the deformation of the battery case 11 or breakage of the guide 10 is not generated and the battery case 11 is normally supplied. If the battery case 11 is abnormally fit to the fitting part 6, when the battery case 11 passes through a guide 10 setting region, a load is applied to the guide 10 and the battery case 11. When the load is larger than the holding force of a magnet for holding the guide 10, the guide 10 is easily separated from a fixing bracket 12, and damage of the dial 5 and the guide 10 can be avoided.

IPC: B24B57/00
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of heap of deposited abrasive grains at cene point by controlling a motor so as to continuously change the number of revolution of a plurality of agitating blades for agitating the slurry stored in a slurry tank. SOLUTION: Motors 56A, 56B for rotating agitating blades 52A, 52B are driven at the same time when the operation of a wire saw is started. With the rotation of the agitating blades 52A, 52B, slurry 40 stored in a slurry tank 34 is agitated by the rotating agitating blades 52A, 52B so as to even the distribution of abrasive grains in the slurry 40. At this stage, the number of revolution of the agitating blades 52A, 52B is continuously changed. In this case, a flow of the slurry 40 inside of the tank 34 generated by the rotation of the agitating blades 52A, 52B is continuously changed. With this structure, the flow of the slurry 40 generated in the tank 34 is an irregular flow. As a result, even in the case where the abrasive grains in the slurry 40 is deposited, heap of the abrasive grains 3 at a constant position is prevented.

Title: Antenna directivity detection system
Inventor: KAIZUKA TOSHIYUKI
IPC: G01S3/42
Filed: 1985-09-06
Abstract: PURPOSE:To improve the operating rate of a circuit while maintaining its reliability by performing control so that a signal for directivity detection is transmitted from one of plural ground stations by switching ground stations. CONSTITUTION:Signals for directivity detection transmitted by the ground stations 2a and 2b are supplied to a tracking receiver 5a through feeding circuits 4a and 4b and a signal synthesizing circuit 9. Then, the signal for directivity detection is sent from one ground station, e.g. 2a and processed by the receiver 5a to detect an error in antenna directivity. At this time, if the signal from the ground station 2a is broken owing to a rainfall, etc., the transmitting station for directivity error detection is switched to the ground station 2b. When the ground stations 2a and 2b are at some distance, the probability that signals circuits for directivity detection are both broken is extremely small, so the operation rate is improved.
