Title: Method and apparatus for measuring depth of fine pattern
Inventor: HAMASHIMA MUNEKI
IPC: G01B11/22
Filed: 1987-03-18
Abstract: PURPOSE:To individually measure the depth or difference in level of a minute hole or groove with good accuracy, by projecting the light from a wavelength variable light source on the surface to be measured as a minute spot and detecting the interference fringe of the zero order light of the reflected light therefrom and the reflected light from a reference surface. CONSTITUTION:The luminous flux from a wavelength variable light source 1 is divided into two by a light splitting interference means 3 and one of them is condensed in a start spot form to be projected on two surfaces 10a, 10b to be measured forming difference in level of the minute pattern provided to the surface of a specimen 10 as sample light by a projection optical system 9 while the other luminous flux is projected on a reference surface as reference light. The respective reflected sample lights from two surfaces 10a, 10b to be measured of the projected spot light go toward an interference means 3 through the optical system 9. The reflected reference light from the reference surface 8 interferes through the interference means 3. The intensity of the interference fringe generated by interference is detected by a photoelectric detection means 14 while the wavelength of the light source 1 is changed and the light path difference between two surfaces to be measured, that is, the depth of the fine pattern can be calculated from the detected spectrum distribution.

Title: Speed change controlling method for v-belt type stepless speed change gear
Inventor: TANAKA YOSHIKAZU
IPC: F16H61/00
Filed: 1982-04-19
Abstract: PURPOSE:To prevent electrical noises from being accumulated, by securely resetting a speed change ratio command signal into a state corresponding to a predetermined rotational position of a speed change motor when the motor reaches the predetermined rotational position. CONSTITUTION:After assembling each V-belt type stepless speed change gear, the number of pulses the rotation by which amount from a maximum speed change ratio position (pulse number=0) is required for a speed change reference switch to be turned ON is tested, and the pulse number NA* thus obtained is stored at a predetermined address in a ROM. Consequently, an actual pulse number NA at the moment the speed change reference switch is turned ON and the pulse number NA* for resetting correspond accurately to rotational positions of a step-motor which is an actual speed change motor. Accordingly, the actual pulse number NA is corrected to an accurate value every time the reference switch is turned ON, so that errors can not be accumulated.

Title: Manufacture of electrically conductive pipe
Inventor: KANEKO KYOJIRO
IPC: B22D23/06
Filed: 1995-02-27
Abstract: PURPOSE: To facilitate manufacture of a highly pure tough silicon pipe by a method wherein conductive materials charged into annular gap formed between two bottomless crucibles are melted by heating from inside and outside with an induction coil and gradually drawn out. CONSTITUTION: Inside-to-outside reversed surface currents are induced on silicon melt 19 formed between two bottomless crucibles 6a, 6b since a current flows through induction coils 7a, 7b. At that time, the silicon melt 19 is stably held in a state of non-contact to the bottomless crucibles 6a, 6b. Further, a current is started to pass through an induction coil 11 to raise temperature of a heat reserving furnace 8, and temperature at an upper end of the heat furnace 8 is kept at a specific temperature. Then, when a drawing out shaft as not given in the figure is lowered, a bottom part of the silicon melt 19 is drawn out from bottom ends of the induction coils 7a, 7b, and dielectric force is attenuated. Therefore, the temperature is lowered, and solidification starts.  Charged silicon materials 17 are newly melted in an upper part of the silicon melt 19, and a silicon pipe 18 is continuously casted.
