Filed: 1983-03-25
Abstract: PURPOSE:To obtain a high-precision spectrophotometer having corrected variance in grating constant by using a direct shaft driving type grating spectrophotometer which is mechanically simple and correcting variation of a diffraction grating automatically. CONSTITUTION:The spectrophotometer M is driven from a short-wavelength side, and after light of lambda1 is detected by a photodetector PD, wavelength driving is further carried on to detect light of lambda2.

In equations 1 and 2, a diffraction constant (d) contains an error and is unknown, and thetao is also unknown. When the number of grating lines is normal, i.e. No/mm., the DELTAtheta in the equation 2 is obtained by calculation. The number of input pulses to the pulse motor corresponding to the DELTAtheta is calculated and stored in the memory of a computer previously. Which one in the memory the number of pulses corresponding to the DELTAtheta corresponds actually to is retrieved, the grating constant is found immediately and a wavelength origin is determined by the equation 1. Further, a constant 2dcosalpha is also fixed and then wavelength lambda is determined by the rotational angle of the diffraction grating.

Abstract: PURPOSE:To prevent useless running of tape at interruption of an input audio signal by applying a reproduced audio signal to a music selection circuit, bringing a tape recorder of the recording side into the recording wait state depending on the no input of the audio signal thereby reducing the cost of the tape recording and simplifying dubbing. CONSTITUTION:When an input audio signal exists, a music selection circuit 7 outputs a high-level signal and when no audio signal exists, the circuit 7 outputs a low-level signal, and when an audio signal is recorded on a tape, record disc or a CD recording medium reproduced by the player 1, a high level signal is inputted to a microcomputer 8 from the circuit 7. The microcomputer 8 checks the signal to keep the tape drive mechanism 9 in recording state. When the audio signal on the recording medium reproduced by the player 1 is finished, the signal input to the music selection circuit 7 is lost and its output goes to low level. The microcomputer 8 discriminates it when the low level signal is consecutive for a prescribed time and brings the tape drive mechanism 9 into the recording wait state.
