Title: Apparatus for measuring carbon potential in furnace atmosphere in reduction atmosphere furnace
Inventor: NAGASHIMA AKIRA
IPC: G01N33/00
Filed: 1989-01-25
Abstract: PURPOSE:To enable highly accurate measurement by a method wherein O2 concentration or CO2 concentration and CH4 concentration in furnace atmosphere is directly measured, and operation value of carbon potential in the furnace atmosphere is compensated based on relation between the CH4 concentration and temperature under such conditions that the furnace atmosphere is in chemical equilibrium. CONSTITUTION:Gas in a furnace is measured from a sampling tube 14 via a gas tube path 16, a filter 20 and a pump 18 by respective concentration meters 22, 24, 26 of CO2, CO and CH4, and the results are input to an arithmetic unit 28. A thermocouple 12 is provided on a furnace wall 10 to measure temperature in the furnace. A computing element 30 of the unit 28 calculates carbon potential from measured concentration of CO2 and CO by specific arithmetic equation assuming that respective reactions in the furnace are in equilibrium. Then, a compensator 32 compensates the calculated value based on difference in this equation which has been calculated in advance and relation between CH4 concentration and the furnace temperature. This enables highly accurate measurement even if the furnace atmosphere has not reached chemical equilibrium.

Title: Optical disk device
Inventor: OKUDA HIROYUKI
IPC: G11B7/095
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device which contains a mechanism to move an optical pickup to an optical disk and can fast converge the vibrations of an objective lens caused by the seek jumps of the optical pickup to attain a fast seek. SOLUTION: Detectors DA to DD are separated into the detectors DA/DB and DC/DD in terms of signals among those detectors DA to DF which construct a photodiode of an optical pickup. These detection signals undergo the subtraction via a comparator 38, so that a position signal POS is acquired for the vibration of an objective lens. A comparator 39 eliminates the RF components detected by the detectors DE and DF out of the signal POS, and furthermore, an LPF 40 detects only the low band components. Thus, the center output signal of the objective lens is acquired, and a tracking servo operation is carried out in the vibration suppressing direction based on the center output signal.

Title: Universal joint
Inventor: INUZUKA KATSUYA
IPC: F16C11/04
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To miniaturize and enlarge a motion angle by providing an intermediate body connected relative-rotatably around a first rotary axis for a joint fixing part and an output body connected relative-rotatably around a second rotary axis crossing with the first rotary axis for the intermediate body. SOLUTION: By the relative rotation of an output body 9 for an intermediate body 3 around the rotary axis ω slanted by a prescribed angle for a rotary axis ϕ, an angle γ is generated between the rotary axis ϕ for the joint fixing part 1 of the intermediate body 3 and the axis χ of the output body 9, in response to the rotary angle β for the intermediate body 3 of the output body 9. By the relative rotation for the intermediate body 3 of the output body 9, the axis χ is rotated around the rotary axis ω while always maintaining a prescribed angle between the center shaft and rotary axis ω. As the intermediate body 3 can be relatively rotated for the joint fixing part 1, if the angle made by the rotary axis ω and axis χ is 30 deg., the motion angle range of the output body 9 becomes 60 deg. at one side. Therefore, the motion angle can be enlarged and the joint can be miniaturized.
