Title: Tracking-error detection method
Inventor: MATSUMOTO YOSHIYUKI
IPC: G11B7/09
Filed: 1993-07-15
Abstract: PURPOSE:To obtain a tracking-error detection method wherein a tracking error can be detected precisely even when spot light which is incident on an optical detection element is deviated. CONSTITUTION:In an optical pickup, an optical beam which is radiated from a light source and which is reflected by the surface of an optical disk being turned and driven is received by a photodetector, and a tracking error is detected in sensor parts divided in the longitudinal direction of the photodetector on the basis of the difference in a quantity of light between the individual divided sensor parts. Its sensor part is provided with at least four divided sensor parts E1, E2, E3, F1, F2, F3, as even numbers, which have been divided in the longitudinal direction, and a tracking-error signal is detected on the basis of the difference in the total sum between output signals of every other divided sensor part.

Title: Robot control method
Inventor: MASUI TOMOYUKI
IPC: G05B19/18
Filed: 1985-09-09
Abstract: PURPOSE:To calculate the joint speed from the hand speed of a robot even in case the peculiar posture of the robot has <=5 degrees of freedom, by adding m pieces of 6-dimensional vectors independent of each other in the form of the column of a Jacobian matrix of the robot having (n) degrees of freedom. CONSTITUTION:A control program stored in a storage 303 decides the direction and the speed of the hand rotation of a robot from the present position and speed of the joint of the robot. Then the angle of the joint is obtained from the count value of a pulse encoder attached to a servo motor which drives each joint. Based on this joint angle, an arithmetic unit 304 calculates a Jacobian matrix and also the rank l of this matrix. Then a peculiar posture of the robot is decided in the case of l<5 and l pieces of independent column vectors are selected from the Jacobian matrix. In addition, independent m pieces of column vectors which are independent of those l pieces of column vectors are produced. Thus a new Jacobian matrix is obtained and used to calculate the joint speed from the hand speed.

Title: Pressure sensor and fluid feeder
Inventor: ITO NAGAKATSU
IPC: G01L9/00
Filed: 1989-07-29
Abstract: PURPOSE:To simplify compensation of temperature by a method wherein current for maintaining an operating body at a constant position against applied pressure of a diaphragm is applied to an actuator while pressure is detected from the current value. CONSTITUTION:When pressure fluid is led into a chamber 7 from an input 7a of a pressure detector 4, a diaphragm 6 is subjected to the pressure so that an operating body 8 is to move upward together with the diaphragm 6 by a distance proportional to the applied pressure. A plunger 10 contacting the operating body 8 moves upward together with the operating body 8 so that the position of its tip is to be changed. On the other hand, a position sensor 17 always detects the position of the tip of the plunger 10 and outputs the detected signals to a control circuit 18. If force for moving the operating body 8 is generated, the circuit 18 supplies current to a coil 11 of an actuator so as to generate force against the above force. This current value and the force generated by the actuator are in proportional relation so that secondary pressure can be calculated from the current value.

Title: Guide cylinder
Inventor: SAWAI YOSHIKAZU
IPC: G11B15/61
Filed: 1981-12-08
Abstract: PURPOSE:To reduce friction when a magnetic tape slides, by obtaining an occupation ratio of a beta phase to an alpha phase on the outer circumferential surface of a guide cyinder greater than said ratio in said guide cylinder. CONSTITUTION:Molten silicon aluminum alloy consisting essentially of aluminum and additive metals, such as silicon, copper and magnesium, at an adequate  mixing ratio is cast in a mold. In this case, a cooling speed is relatively slow  and deposition is performed for segregation of a beta phase in the grain boundary  of an alpha phase. Specially, the cooling speed of the outer circumferential surfaces of guide cylinders 2a and 2b is made lower than that of the inner circumferential surfaces to achieve the segregation of the beta phase more near the outer circumferential surfaces. Consequently, the beta phase exposed more on the outer circumferential surfaces of the guide cylinders which are tape sliding surfaces, so a coefficient of friction to a magnetic tape is reduced greatly.

Title: Method and apparatus for sealing air supply hood for pressure sintering facility
Inventor: OKADA TSUTOMU
IPC: C22B1/20
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To suppress gas leakage from a hood surely by realizing noncontact increase of pressure loss between the surface layer part of material filling layer and the lower end part of skirt of a pressure air supply hood disposed above the material filling layer in a lower suction sintering machine thereby sucking gas leaked from a sealed part downward. SOLUTION: Gas leaked from between the surface layer part of a material filling layer 2 and the lower end part 13 of skirt of a pressure air supply hood 3 is sucked downward by an exhaust blower from above the material filling layer 2 thus accomplishing seal between the pressure air supply hood 3 and the material filling layer 2 required for pressure sintering method. When a sufficiently wide stretching part 14 is provided at the lower end part 13 of skirt of the pressure air supply hood 3, for example, leakage gas from the hood 3 can be sucked downward by an exhaust blower and deficient volume of air can be taken in from the outside. Since a pressure loss mechanism for leakage gas is provided and leakage gas is sucked downward, noncontact suppression of leakage gas is ensured resulting in a reliable seal.
