Title: Temperature control method of extra-high pressure generator
Inventor: NAKAMURA TSUTOMU
IPC: G05D23/24
Filed: 1983-03-09
Abstract: PURPOSE:To realize accurate temperature control without using any thermocouple by using high-melting metal which has linear temperature variation due to electric resistance variations as a heating body and utilizing the heating body itself as a temperature sensor. CONSTITUTION:Electric power necessary for synthesizing diamond, cubic system boron nitride, etc., is applied through an electrode 9 to the tantalum heating body 10 incorporated in a pressure medium 5. If temperature variation occurs when this electric power value is maintained for a long period, the heating body 10 has electric resistance variation corresponding to it, so the applied electric power is fed back so that the initial resistance value is obtained, thus holding the temperature constant. Consequently, temperature control precision is greatly improved and the need of inserting a thermocouple for internal temperature measurement and control is eliminated.

Title: Position measuring apparatus
Inventor: DEIITERU MITSUHIERU
IPC: G01D5/26
Filed: 1990-02-23
Abstract: PURPOSE: To provide a position measuring instrument which can measure the position of an object to be measured with high resolution by utilizing diffracted partial luminous fluxes in such a way that the fluxes are made incident to one reflecting element after convergence by means of at least one deflecting element and deflected so that the fluxes can again appear by diffusion on the deflecting element after coming out of the reflecting element. CONSTITUTION: The laser beam emitted from a laser 4 is diffracted by a phase grating 2. Diffracted partial luminous fluxes -ϕ and +ϕ appear on a second diffraction grating 3 and are again diffracted by the grating 3. The order of diffraction O is stopped down by means of a stop 5 before the fluxes -ϕ and +ϕ are generated on the grating 3. A reflecting element composed of a triple mirror 6 is positioned after the grating 3. The grating 3 and mirror 6 are adjusted so that the fluxes -ϕ and +ϕ can meet each other at one point. The fluxes -ϕ and +ϕ are again diffracted when the fluxes pass through the grating 3 after coming out of the mirror 6 and appear on the grating 2 by which the fluxes are again diffracted.  Then the interfered and diffracted partial luminous fluxes are converted into measurement signals which are shifted from each other in phase.
