摘要:
When a work is set on a hot plate and a heat treatment is started and the like, an addition waveform of a target temperature is formed based on a previously formed data of an adjustment value, and a temperature is controlled by adding the addition waveform to the target temperature SP, and with the data of the adjustment value, the variation in temperature of the work is prevented using an interference matrix showing a relation between the target temperature SP and the temperature of the work.

A plurality of individually corresponding heaters and temperature sensors are provided along with a plurality of a PID control means. An average temperature/gradient temperature calculating means calculates the average temperatures of the temperatures measured by the temperature sensors and the gradient temperatures based on the measured temperatures. Each of the PID control means outputs an operation signal so that the average temperatures or gradient temperatures may be made equal to the desired values. A distributing means distributes the operation signal from each of the PID control means to each heater so that control by the PID control means may produce no effect on the control of the other PID control means.

An reaction vessel utilizes a sample carrier composed of a magnetic core and a surface coating effective to support sample of protein or peptide. The sample carrier is floated magnetically and positioned within a reaction chamber. Edman reagent is applied to the sample to effect amino acid sequence analysis of protein or peptide from amino-terminal. By such construction, reaction efficiency is increased to produce sequentially thiazolinon amino-acid derivatives to thereby increase number of identified remaining amino acids, thereby enabling microanalysis of sample.

An objective lens apparatus for an optical disc player comprises an objective lens holder rotatable about a center axis, an objective lens carried by the holder at a location spaced from the center axis, an optical member, a magnetic flux generating member for generating magnetic flux, and tracking and focusing coils interacting with the magnetic flux for effecting tracking and focusing adjustments of the objective lens. The optical member rotates simultaneously with the lens holder and leads light which is incident along the center axis to the objective lens in a direction parallel to the center axis thereby eliminating optical modulation of the light caused by rotation of the lens holder in the tracking direction.

The number of wirings and the number of switching elements are decreased in a heater, a sensor, and the like. First to ninth heaters that heat a hot plate are connected into a matrix form between first power lines in a row direction and second power lines in a column direction. The first power lines are connected to one end of a power supply through three switching elements, respectively. The second power lines are connected to the other end of the power supply through three switching elements, respectively. On-off control is performed to the switching elements to select the heater to be driven. Therefore, the number of power lines and the number of switching elements are decreased compared with a conventional technique in which the heaters are separately wired.
