Abstract: PURPOSE:To obtain a correct measured value by finding the reverse matrix of a characteristic matrix showing the state of interference caused between axial components in advance and carrying out correction arithmetic operation using this reverse matrix by an analog arithmetic circuit. CONSTITUTION:Such coefficients K11 - K13, K21 - K23, and K31 - K33 that Ax=K11Vx+K12Vy+K13Vz, Ay=K21Vx+K22Vy+K23Vz, and Az=K31Vx+ K32Vy+K33Vz are hold are found, where Ax, Ay, and Az are the X-axial component, Y-axial component, and Z-axial component of an external force operating on an operation point and Vx, Vy, and Vz are voltage values obtained according to a bridge circuit consisting of plural resistance elements. Then the values of the terms in the right members of the relational expressions are calculated by using analog multipliers 101 - 109 and the right members are added by using analog adders 111 - 113 to obtain the detected values Ax, Ay, and Az from the arithmetic results.

Title: Hoisting and conveying device using linear motor
Inventor: KURATA HIDETOSHI
IPC: B60L13/03
Filed: 1985-04-11
Abstract: PURPOSE:To obtain a large float-up force to enable stable conveyance with the use of a hoisting system, by allowing jet air to impinge upon the lower surface of a floating plate so that a movable member is floated up by means of the floating plate. CONSTITUTION:A movable member 5 is reciprocated on a predetermined conveyor path by means of a linear motor 15 composed of a stator 13 and a secondary induction member 10. During running of the movable member 5 air fed into an air supply duct 1 from an air supply pipe 3 is jetted upward from air jet ports 4 to be allowed to impinge upon the lower surface of a floating plate 6 so that the movable member 5 and a material 9 to be conveyed are floated up. Further, air used for the float-up is in part fed downward through a slit section 2, and thereafter, flows, being guided by a lower section cover 16, and the remaining part of air is allowed to flow into a cover 11 in order to cool the linear motor 15. With this arrangement, a large float-up force may be obtained, and therefore, it is possible to carry out stable conveyance by means of a hoisting system.

Title: Measuring method for torque
Inventor: ANDO MASAO
IPC: G01L3/14
Filed: 1986-04-03
Abstract: PURPOSE:To prevent a measurement shaft from rotating by using a differential gear mechanism. CONSTITUTION:A prime mover is connected to the input shaft 1 of the differential gear mechanism A, a load is connected to an output shaft 2, and a measuring instrument 4 is connected to the measurement shaft 3. In this case, the speed reduction ratio of the input shaft 1 and measurement shaft 3 is set to 2:1, so torque measured by the measuring instrument 4 is twice torque outputted by the prime mover. Further, the speed reduction ratio of the output shaft 2 and input shaft 1 is 1:3. The measurement shaft 3 does not rotate, so a simple instrument like a spring scale can be connected as the measuring instrument 4.

Title: Disk revolving speed controller
Inventor: SUZUKI KEIICHI
IPC: G11B19/28
Filed: 1984-04-18
Abstract: PURPOSE:To reduce the disk revolution variance and to reduce the jitter of a detection dats signal for the titled device of a player, by deleting a fundamental signal wave component out of a clock component. CONSTITUTION:A notch filter 12 which deletes only a fundamental signal wave component f0 of a clock is put into the next state of an LPF8. The LPF8 is set to suppress the high frequency components of the secondary level or higher of the clock component. The disk revolution variance owing to the clock component of a pulse is reduced by 1/n<2> to the degree number (n) of a higher harmonic frequency. In other words, said revolution variance is suppressed by deleting the basic component (n=1) through the filter 12. Thus it is possible to delete the clock component of a speed error pulse per revolution of disk, especially the fundamental signal wave component. This can decrease considerably the jitter of the data signal due to the revolution variance of a motor 2.

Abstract: PURPOSE: To provide possibility of using a graduation plate in any shape by forming a pointer needle from a beam of light, making its brightness variable, and automatically adapting in compliance with the shape of the graduation plate. CONSTITUTION: Through slip contact 18, feeder line 17, etc., electric current reaches a semiconductor light source 30 and fed to a laser diode 31, which produces an indicator of light. From an outlet opening 15, a beam of light 11 is emitted, which runs against a scattering plate 40 overlapped on a graduation plate 41 to be scattered so that scattered beams of light 10 are produced, which are visible. The beams 10 are reflected by a crown-shaped mirror 26 and returned in the direction right opposite to the incident direction, where the brightness is increased. Owing to the slip contact 18, the current flows without hindrance to the shafts 24, 25 for rotation, a shield casing 23, and the light source 30.  To prevent emission of diffracted beams of light resulting from the outlet opening 15, its diameter is regulated using a stud bolt 13 to be inserted from an access opening 12, and thereby it is possible that the brightness of the beams of light 10 is adjusted to meet the requirement imposed.
