Title: Multiplier
Inventor: AOKI TAKASHI
IPC: G06F7/533
Filed: 1979-08-21
Abstract: PURPOSE: To increase the velocity of multiplication by providing the path through which the complement of the multiplicand 1 can be set directly to the register which stores the partial product.  
     CONSTITUTION: The multiplier B shown by the equation is expressed by the sum of the several partial polynomials and -b 0 , and then the partial product of the multiplicand A and -b 0 . After this, the partial product is obtained between A and each partial polynomial, and then the product of A and B is obtained from the general sum of all partial products. In such multiplier, B and A are stored in the multiplier register 2 and the multiplicand register 1 respectively. And when the lowest-rank bit of B is 1, the complement of 1 of A is set directly to the register 10 which stores the partial product in the fixed timing and via the complement circuit 8. At the same time, 1 is set to the lowest-rank bit of the register 9 in the same timing. As a result, the complement of 2 of the multiplicand is set to the registers 9 and 10 each. And the multiplication can be carried out with the same step number and regardless of 1 and 0 of the lowest-rank bit of the multiplier.

Title: Manufacturing method of disk substrate, and disk substrate
Inventor: SASA TAKESHI
IPC: G11B5/84
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To uniformalize a thickness in the neighborhood of an outermost circumference to be almost the same as that on the side of an inner circumference, and to make it possible to set a recording region up to near the outermost circumference by filling a closed space of a metallic mold die with a fused resin material and curing it, and removing the outer peripheral part after having molded it a little larger in diameter than a desired diameter. SOLUTION: When a disk substrate 1 of a resin material is molded by using a metallic mold die, thickness near the outermost circumference becomes larger than that near the side of the inner circumference. As counter measures for this, an outer diameter of a metallic mold die cavity is set a little larger than a desired one, to mold the disk substrate 1 having a diameter larger than desired one, and the outermost circumferential portion is removed. As for the removal of the outermost circumferential portion, the disk substrate 1 is mounted on a spindle motor 20; is covered with a pair of an upper and a lower covers 21, 22; is irradiated with laser light by operating to rotate a spindle motor 20; and the outermost circumferential portion is removed.  Thus, it is possible to achieve a disk with a uniform thickness near the outermost circumference as almost the same as that near the side of the inner circumference.

Title: Detection of abnormality in temperature sensor
Inventor: YOSHIDA MASAO
IPC: G01K7/16
Filed: 1980-08-05
Abstract: PURPOSE:To detect the abnormality of a temp. sensor without degrading its temp. detecting resolving power by providing an amplifier which amplifies the output voltage of the temp. sensor, and detecting the abnormality of the temp. sensor from the input voltage of this amplifier. CONSTITUTION:A voltage amplifier 3 is inputted with the detecting voltage VA at the connection point (a) of a thermistor 1 and a resistance 2, amplifies this and outputs output voltage VB. On the other hand, the detected voltage VA for abnormality of the sensor 1 is taken from the input side of the amplifier 3. The resistance value of the sensor 1 does not go to 0OMEGA in a practicable measurement temp. range, and outputting of VCC does not occur when the voltage VA is normal. Hence, abnormality is easily detected from the attainment of VCC by the voltage VA only when the sensor 1 is shorting. In case the sensor 1 is disconnected, the detected voltage goes to 0V. In this case, the case when the maximal voltage is generated is decided as a shortcircuit, and the case when the minimal voltage is generated as a disconnection. The resolving power and control characteristics of temp. measurement are improved by taking the practicalbe range relatively narrow.
