Title: Atomic absorption analyzer
Inventor: ITOU HARUMASA
IPC: G01N21/31
Filed: 1978-04-11
Abstract: PURPOSE:To eliminate the error due to the background absorption by using as a light source both a hollow cathode lamp and a heavy hydrogen lamp to divide the spectrum obtained into portions containing and not containing the resoannce spectrum and by obtaining the difference between the two detecting signals. CONSTITUTION:The beams from a hollow cathode lamp 1 and from a heavy hydrogen lamp 2 which is lit in a pulsating manner by a pulse power source 3 are overlapped by a semitransparent mirror 4 and are made to pass through an atomizer 5 so that they are subjected to spectroscopy by a monochrometer 6. After that, the overlapped light is divided by a separating mirror 7 into a flux of light L4 containing the resonance spectrum S1 of the element being measured and the spectrum S2 therearound and the flux of light L3 containing only the spectrum S2, both of which are detected through detectos 9 and 8 by synchronous detecting circuits 11 and 10, respectively. The difference inbetween is then obtained by a difference detecting circuit 12 thereby to obtain the measured value which is compensated in respect of the influence of the background absorption while coming only from the resonance absorption of the element.

Title: Cylinder discriminator for internal combustion engine
Inventor: TOMIZAWA NAOMI
IPC: F02D45/00
Filed: 1988-02-26
Abstract: PURPOSE:To make a cylinder discrimination performable while using one pickup system crank angle sensor by discriminating a cylinder discriminating pulse signal in comparing the ratio of pulse width of the pulse signal to time width between pulse signals with the specified value. CONSTITUTION:A signal out of a crank angle sensor 10 is inputted into a microcomputer 30 after being shaped by a waveform shaping circuit 20 and processed therein. When a pulse signal out of the crank angle sensor 10 is downed, value of a timer 40 counting a clock signal is read in, setting this value down to Ta, and when it is started up, the value of the timer 40 is read in, setting this value down to Tb. If the ratio Ta/Tb of the pulse width Ta of the pulse signal to the time width Tb between pulse signal is less than the specified value, it is regarded as a cylinder discriminating pulse signal. With this constitution, the cylinder discriminating pulse signal on the same output line as a reference pulse signal is discriminated while using one pickup system crank angle sensor 10, and thus a cylinder discrimination is performable.

Title: Rotary compressor
Inventor: INAGAKI MITSUO
IPC: F04C23/00
Filed: 1983-03-14
Abstract: PURPOSE:To make it possible to prevent troubles such as seizure and the like by rotating a rotor in the direction reverse to the revolving direction of the rotor by the engagement of a gear and relatively delaying the slide contacting speed of the tip end of a vane and liner. CONSTITUTION:When a drive shaft rotates around a rotary shaft A in the direction shown by arrow N1, the rotor 3 which is axially supported on a second shaft B which is excentric with respect to the rotary shaft A revolves toward the direction indicated by a one-dot chain line on a revolving onbit. Since a driven shaft axially supports the rotor 3 on the rotary shaft B, the driven shaft rotates around the rotary shaft A. At this time, the rotor revolves while maintaining a minute gap between the outer periphery thereof and the inner peripheral surface of a liner 5. Upon this occasion, the slide contacting speed between the rotor 3 and the liner 5 and between the rotor 3 and the vane tip end becomes extremely slow so that wear and seizure phenomena of the slide contacting part can be evaded.

Title: Device for power unit and switching power unit
Inventor: INABA KATSUMI
IPC: H02M1/08
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To dispense with a control terminal by collecting the operation voltage of a circuit means for performing the operation of a soft starting function, a fixed voltage function, and a protective function against overvoltage, on different voltage levels, into the voltage at one feedback terminal. SOLUTION: In a soft start function, the operation voltage generated with an internal operation voltage generating circuit VS is given to a feedback terminal FB, in short, the positive terminal + of a compactor CO2 through a diode D6 and a resistor R5. In a fixed voltage function, the quantity of emission of a light emitting diode ED1 and the quantity of conduction of a light receiving transistor RQ1 change, accompanying the change of the output voltage between output terminals OUT1 and 2, and the voltage of the feedback FB changes, corresponding to the output voltage. Moreover, in a protective function against overvoltage, the light receiving transistor RQ is turned, and the feedback terminal FB, in short, the positive terminal + voltage of a comparator CP1 for overvoltage detection goes up.  This way, each kind of operation voltage is collected to one feedback terminal, so the control terminal becomes needless, and the number of external-attachment terminals can be curtailed.
