Only one switch element of the switching circuit 6 is selected by a controller 9, the other switch elements are opened or connected to a common and the inputted signal is attenuated to a prescribed value. In this case, a noise generated caused by the capacitance between poles of the semiconductor switch element is inputted to the R-2R ladder resistance network 7 and the noise is attenuated similarly as the input signal. Then the input signal is inputted to the buffer amplifier and then outputted at an output terminal 5.

Title: Apparatus for analyzing microstructure of absorbing end of x ray
Inventor: TAKEUCHI YUKA
IPC: G01N23/08
Filed: 1989-10-16
Abstract: PURPOSE:To remove the effect of the fluctuation of an X-ray source and to remove the effect of mixture of continuous X rays by splitting the X rays emitted from the X-ray source, and inputting the X rays on a sample through a monitoring X-ray detector on the front side of the sample. CONSTITUTION:At first, wavelength scanning is performed without a sample S. The detected output of X rays from a monitoring X-ray detector 4a and a sample- transmitted X-ray detector 5 are obtained, and ratio between both outputs is stored. Then, the sample S is mounted on a sliding frame 7, and wavelength scanning is performed. The output of the detector 4 is multiplied by the above described ratio, and the multiplied value is computed. This value is the value which is obtained by detecting the intensity of the X rays inputted into the sample at the same sensitivity as that of the detector 5. Therefore, the absorbing rate of the sample X is obtained based on the ratio between this value and the output of the detector 5. In this apparatus, since the detector 4 is placed on the front side of the sample S, monitoring of the X rays projected on the sample is performed at the same time as the measurement of the absorption of the X rays in the sample S. Thus the effect of the fluctuation of an X-ray source 1 can be perfectly removed.

IPC: G01M99/00
Filed: 1985-12-02
Abstract: PURPOSE:To facilitate the trouble shooting of an air conditioning equipment for a vehicle, by discriminating a trouble of a photodiode from an output voltage of a photodiode when the photodiode is forwardly or reversely biased. CONSTITUTION:When a photodiode 17 enters a trouble shooting routine, a high-potential comparison signal is applied to a comparator 29 from a microcomputer 23. On the other hand, a reference voltage V3 is applied to the comparator 29 while the diode 17 is forwardly biased. Now when the diode 17 is not disconnected, an output voltage of an amplifier 20 becomes a larger voltage V1 than the voltage V3. When a sensor 17 is disconnected or off in the connection, the output of the amplifier 20 becomes the voltage V3. Then, when the output of the amplifier exceeds the voltage V1, the diode 17 is discriminated to be disconnected or off in the connection and the trouble of the diode 17 is displayed. Then, the output voltage of the amplifier 20 is below the voltage V1, the sensor 17 is reversely biased. When the output voltage of the amplifier 20 is above a voltage V2 higher than the voltage V3 corresponding to a sunshine, a photosensor is discriminated to be short-circuited.

Title: Ink jet recorder
Inventor: MITA YASUHIRO
IPC: B41J2/01
Filed: 1985-12-02
Abstract: PURPOSE:To restrain a temperature rise in the vicinity of a platen part, reduce power consumption by heat generating resistors and achieve clear recording with the same quality on general-purpose recording papers, by a construction wherein a part of a platen is constituted of at least two heat generating resistors, and a part of the heat generating resistors has a temperature self-controlling function. CONSTITUTION:After a recording medium 8 is set to a recorder, parts on the side I of heat generating resistors 4 divided into 12 parts are energized to preheat and heat the medium 8. A heat generating resistor controlling circuit so controls that the heat generating resistors on the side I are always operated irrespective of the rotation of a platen 3 as a printing operation of a head 1 proceeds, and the operating conditions of the heat generating resistors 4 are switched each time the platen is rotated by 1/12 of one revolution. In this way, power consumption is decreased by about 30%, as compared with the case where the heat generating resistor is not divided. As the temperature of the recording medium is higher, the period of time required for fixing an ink is shorter, and the diameters of dots more easily converge to a substantially fixed value, so that clear recording with the same quality can be performed irrespective of the quality of a recording paper.
