Title: Method for sensing magnetic moment of sample and torque magnetometer
Inventor: SPAGNA STEFANO
IPC: G01N27/72
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To measure the magnetic characteristics of an extremely small anisotropic sample such as a thin film by providing a pair of piezoelectric resistors that is placed on the surface of a bridge means and is provided in parallel with an interval. SOLUTION: Piezoelectric resistors R11 and R12 are indicated in a bent form to improve sensitivity, and are preferably constantan. The detection resistors are provided at legs 46 and 47. The piezoelectric resistors R11 and R12 are connected so that the surface contacts legs and resistance changes due to the bending or deflection of the legs, thus resulting in a signal (ΔR) that can be detected, compared, and processed by some sort of proper means. A Wheatstone bridge is especially useful since it detects the ΔR of the resistors R11 and R12 extremely easily, compares the change, and directly indicates the direction and amount of bending or deflection being generated at legs 46 and 47 due to an applied magnetic field caused by the bridge output.

Title: Method for detecting gas
Inventor: NISHIKAWA MASAHIRO
IPC: G01N27/12
Filed: 1982-04-21
Abstract: PURPOSE:To carry out the discrimination of the kind of a gas and the detection of the concn. thereof simultaneously in good reproducibility, in the shape of the variation in the resistance value of a gas detecting element due to the rising and the falling in the temp. of said element, by utilizing the part during a time when the temp. of said element is fallen. CONSTITUTION:The drawing shows the result in the calculation of Ro'/Rg' corresponding to each temp. of a gas detecting element during the falling in the temp. of said element at a time when the temp. of said element is raised or fallen in an atmosphere containing each kind of a gas at a dfinite concn. The solid line in the drawing shows the result of isobutane (2,000ppm) and the two- dotted broken line therein shows methane (2,000ppm) respectively. As is apparent from the foregoing, the characteristic curve of Ro'/Rg' with respect to the temp. of the element shows an intrinsic shape due to the kind of a gas. Therefore, the kind of a gas can be discriminated by the difference of said shape. The shape of the intrinsic characteristic curve has no relation with the concn. of a gas and only an absolute value is varied. The concn. dependency of Ro'/Rg' with respect to a gas is measured to be capable of knowing the concn. of a gas by the value of Ro'/Rg' corresponding to the definite temp. of the element.

Title: Multi-processor device
Inventor: IWASAKI OSAMU
IPC: G06F15/17
Filed: 1987-03-23
Abstract: PURPOSE:To improve the data processing efficiency by using a shared memory as well as a processor controller which controls plural exclusive processors of different types that can process a specific data structure with high efficiency. CONSTITUTION:When a binary tree processor 11 carries out an instruction of a shared memory 15, the processor 11 obtains an argument from another exclusive processor and therefore gives a processing request to a processor controller 14. The controller 14 gives the start commands to a frame processor 12 and a rule processor 13 and sends a processing end instruction to the processor 11 as soon as the evaluation is through with arguments of both processors 12 and 13. Thus the processor 11 produces a binary tree node and ends its processing. In such a way, the exclusive processors 11-13 give the processing requests to the controller 14 except those data treated by those processors themselves. As a result, the data processing efficiency is improved even when the data on a new structure is processed.
