IPC: G01N21/35
Filed: 1995-06-12
Abstract: PURPOSE: To correctly measure a concentration of a gas even by a deteriorated laser, by storing the gas to be detected and a reference gas in a detection gas cell and a reference gas cell respectively, differentiating signals of laser light passing through the cells thereby to obtain a gas signal, and measuring an ambient pressure and concentration of the gas from the gas signal. CONSTITUTION: Light of a distribution feedback-type semiconductor laser 10 which is made constant in temperature by a Peltier element 11 and a Peltier element power source 12 is swiped in one direction by a rectangular wave bias current modulated with a sine wave alternating currant of an oscillator 14, and diverged by a photocoupler 3. The diverged lights are, passing through optical fibers 9b, 9c, gases in a detection and a reference gas cells 4, 5 and optical fibers 9d, 9e, brought. into photodetectors 6, 7, respectively. Lock-in amplifiers 18, 19 detect, from detection signals of the detectors 6, 7 signals synchronous with frequencies of the oscillator 14 and a frequency-multiplier 16 respectively, and input the signals to a differential device 21 via an analyzing recorder 20.  Noise components are removed through this differentiation, and only gas signal components are obtained. A concentration and a pressure of the gas are obtained from a peak value of the gas signal.

Title: Power source circuit for jet bath
Inventor: IMAMURA YOSHINORI
IPC: A47K3/00
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To shut off the power source circuit of a DC motor and an AC power source line immediately when there is a shorting fault of the DC motor by shutting off the AC power source line by activating a circuit breaker, thereby stopping the DC motor in case pump voltage falls down to reference voltage or below. SOLUTION: If the shorting of a coil of the DC motor 5 occurs at the time of current supply to a DC pump 5, overcurrent flows instantaneously to the DC motor 5 but the switching operation is instantaneously stopped by an overcurrent protection circuit 25 disposed at a switching power source 2 and, therefore, the voltage impressed to the DC motor 5 turns to 0. Then, the voltage drop is detected by a pump voltage drop detecting circuit 35 and the signal of the motor voltage zero is sent to a shutting section 63 of the circuit breaker 6, by which the power source circuit 10 and the AC power source line are shut off and the supply of the current to the DC motor 5 may be stopped. Since both are shut off immediately without the continuation of the operation until abnormality occurs and, therefore, safety is improved.

IPC: G11B21/08
Filed: 1995-05-19
Abstract: PURPOSE: To obtain a compact disc reproducing device in which a target index of a target melody (track) in a compact disc can be searched quickly. CONSTITUTION: Variation is detected in the index number read out from the sub-code area of a CD 3 and the address (time data) of CD is detected at the time of variation.

Abstract: PROBLEM TO BE SOLVED: To improve detection precision for acceleration by calculating acceleration on the basis of the time necessary for counting the optimum number of pulses according to vehicle velocity. SOLUTION: An internal combustion engine 10 drives a propellar shaft via a torque converter 11 and a transmission 12, and the gear ratio is controlled according to the outputs of transmission input and output velocity sensors 13, 14.

Abstract: PURPOSE:To prevent the degradation in short distance performance and to allow the prevention and correction of the fluctuation in aberration up to the very short distance by introducing an aspherical face lens into a rear group. CONSTITUTION:A stop is disposed nearer the object side than the aspherical face lens in the rear group G2R and the focusing to the short distant object is executed by extending the rear group G2R to the object side along the optical axis. The equation I is satisfied in this case if the radii of curvature of the extreme object side and extreme image side of the positive lens component in the rear group G2R are designated respectively as ra, rb. Namely, the lens having the negative face refracting power which has the effect opposite to the effect of lowering the positive face refracting power by lowering the incident height of the rear group G2R at the time of extending the rear group G2 having the positive refracting power to the object side is introduced into the rear group G2R to attain the adequate disposition of the positive and negative refracting powers, by which the above-mentioned effects are offset each other and the fluctuation in the respective surface refracting powers is decreased. The fluctuation in the comatic aberration is minimized in this way.
