Abstract: PURPOSE:To prevent fluctuation of oscilation wavelength due to variation of temperature, by forming a reflection preventing film on one side of output face of a laser element, and by causing light put out from said face to reflect and return through etalon at least once. CONSTITUTION:By providing a semiconductor laser element 3 with two parallel output faces 4 and 5, a resonator is provided and, at the same time, the element 3 is prevented from resonance. In this mechanism, one output face 5 is provided with a reflection-preventing film, such as SiO2 film etc., to eliminate reflection, and all the lights 7 put out therefrom are converted into parallel rays using a lens 8. And then, these lights are vertically radiated into two etalons 1 and 2 having different lengths, and the lights are caused to reflect and return from the reflecting faces 9 of the etalon 2 which are set to 100% reflecting positions. While resonance wavelength existing in gain distribution of the element 3 is thus oscillated in the etalons 1 and 2, as it is possible to provide the etalons 1 and 2 by keeping away from the element 3, the etalons 1 and 2 can be prevented from being influenced by the heat generating in the element 3.

Title: Method of decontaminating nucleic acid amplification reaction
Inventor: MERINDA ESU FUREIZAA
IPC: C12Q1/6848
Filed: 1994-05-11
Abstract: PURPOSE: To inactivate a contaminant amplicon in an isothermal nucleic acid amplification reaction, e.g. in SDA, Qβ and 3SR.  
     CONSTITUTION: This method for removing a contaminant in a nucleic acid amplification is to integrate dU instead of thymidine (T) into amplicons produced by the amplification. In the case that the amplicons contaminate the next amplification reaction, they are inactivated as a mold by treating with UDG (i.e., becoming incapable of amplifying). Since an isothermal amplification does not involve a high temperature, the UDG is inactivated in an interval before the next amplification by containing Ugi as a UDG inhibitory protein. The integration of dU is found to increase the amplification capacity of SDA as compared with a normal SDA reaction. This method is also used for detecting UDG activity in a reagent or a sample.

Title: Diagnostic/control method for fault of actuator
Inventor: FURUYA MASATOSHI
IPC: B64G1/24
Filed: 1992-04-17
Abstract: PURPOSE:To diagnose the fault of an actuator without using any action sensor by calculating an error from the force and the torque value obtained from the action signals as well as the force applied to a mobile object and the estimated torque value and also by extracting a prescribed rule out of a trouble diagnostic rule data base. CONSTITUTION:When the fault of an actuator is diagnosed, a signal (an estimated operator) equivalent to the estimated value of the driving force that supposedly affected a controlled system is obtained from a control variable 14 based on an adverse model 109 of the controlled system. At the same, an operator 27 is obtained from an action signal 18 based on an action signal converting part 110. Meanwhile only the rule corresponding to the signal 18 is extracted out of those rules produced by the driving force generated from an individual operation of each actuator diagnostic rule base 111. An error 28 between the operator 27 corresponding to the signal 18 and a driving force estimating element 25 is set to the extracted rule as an input variable. Then a trouble degree 29 is outputted.

Inventor: AOYAMA TORU
IPC: H02P9/14
Filed: 1993-04-23
Abstract: PURPOSE:To effectively control an exciting current and to easily release this control function. CONSTITUTION:A bias resistor 274 is connected between an L terminal and an IG terminal of a voltage controller 2. The resistor 274 biases an L terminal voltage substantially to a battery voltage at the time of cutting OFF a transistor 281. The L terminal voltage becomes a voltage between a collector and an emitter of the transistor 281 at the time of driving a charge lamp 5. An exciting current limiter 25 turns on a transistor 254 when the exciting current is a predetermined value or more, thereby holding an output transistor 24 in a cut-off state. An inhibiting circuit 27 turns on a transistor 273 when the L terminal voltage is Ve or lower which is lower than the voltage between the collector and the emitter of the transistor 281, thereby cutting OFF the transistor 254 of the limiter 25.
