Title: Measuring system for gas transmissivity by means of infrared rays
Inventor: DOI SHIYOUJI
IPC: G01N21/39
Filed: 1982-01-19
Abstract: PURPOSE:To improve a resolution, by a method wherein outputs of a circuit for respectively holding outputs of a collecting element as a sample and a sample-holding circuit are repeatedly added using a wavelength-varying laser as a light source, and outputs of an adding device for 2 systems of a long optical path and a short optical path are divided. CONSTITUTION:When an adding is repeatedly conducted by repeating adders 9a and 9b, both signal levels outputted to points X1 and X2 increase, and as a result, S/N of each signal is improved. After the respective signals are inputted to a divider 10 and a ratio between the two signals is found, they are inputted to a CPU2 and are fetched from an output terminal 25. This first finds a gas transmissivity to a wavelength lambda1. In the followings, an angle of a grating forming a spectrometer 1 is further changed in a manner described above by means of a signal from a CPU2 and simultaneously a laser driving current is changed, and this causes a laser emitting wavelength to attain a value of a lambda3 from a value of a lambda2 and enables to perform a measurement of gas concentration in the wavelength of the lambda3. Such gradual changing of the angle of the grating, a laser element temperature, and a laser driving current enables finding of a gas over a wide wavelength range each time they change and causes obtaining of a spectrum of gas.

Title: Power amplifier
Inventor: KAARUUHAINTSU IDERAA
IPC: H05K7/20
Filed: 1995-01-20
Abstract: PURPOSE: To raise the operating voltage of a power amplifier so as to discharge high-loss power from the amplifier by providing a current-compensated choke which shows an inductance when uneven current distribution occurs between serial circuits on one bridge arm. CONSTITUTION: Chokes Dr not only make the current distribution uniform between individual serial circuits, but also become current limiting inductances between bridge arms 1 and 3 and between bridge arms 2 and 4. The distortion which occurs when an electric current passes a zero point is avoided by switching the transistors of the two serially-connected bridge arms. In addition, chokes Dr11-Dr4N also work as filter inductances. The chokes Dr11-Dr4N are connected in series with filter chokes Dr1-Dr4 and increase serial inductances. The current compensation, which prevents the chokes Dr11-Dr4N from operating as inductances while an active current is evenly distributed, does not effect the actions of the chokes Dr11-Dr4N as filter inductances.
