    Abstract: PURPOSE:To make possible always stable and accurate weight displaying by holding weight values and converting and displaying the same to digital values only when the measuring system of the scale is not vibrating. CONSTITUTION:A load weight is force balanced or displacement balanced by gravity or elastic force and the force or displacement reguired for the balancing is converted 10 to digital quantity which is then displayed 8. And a circuit 11 which detects 2 the output state of the detector 9 of the load weight and generates a holding signal B when it is at a fixed value in the specified period is provided and the output of the detector 9 is held by the signal B, whereby digital displaying is accomplished. The circuit 11 consists of a circuit 3 differentiating the output of the detector 9, a saw tooth wave generating circuit 4 which is reset by the differentiated output, and a circuit 7 which generates the output signal when the saw tooth wave reaches the specified threshold value.

    Abstract: PURPOSE:To sufficiency secure a display picture and to make it possible to discriminate measuring conditions of many items, by separating the display picture of a spectrum and the display picture of measuring conditions and chang ing over said pictures according to necessity. CONSTITUTION:A measuring condition inputted from a measuring condition input key 23 is stored in a memory 4-2 for a picture B and displayed on CRT 30. The measuring condition is then read from the memory 4-2 for the picture B by the input of a scanning start key 22 and written in a spectrometer control ler 16 and, thereafter, the wavelength scanning of a spectrometer 14 is started. Subsequently, the spectrum data sent from a spectrometer part 10 is stored in a memory 4-1 for a picture A through an operation part controller 18. The display of the CRT 30 is changed over to the data display of the memory 4-1 for the picture A simultaneously with the start of scanning and the display of a spectrum is performed. When the measuring condition is confirmed on the way, a picture-B display key 21 is pushed and the data of the memory 4-2 for the picture B is displayed on CRT 30 and the measuring condition can be confirmed.

    Abstract: PURPOSE:To permit the automatic displacement of a light source or reflecting mirror and the setting of the light source to a use position by supporting displaceably the light source or reflecting mirror via a shape memory alloy and deforming the shape memory alloy by the heat from the light source. CONSTITUTION:The shape memory alloy 10 on a heavy hydrogen lamp 2 side of a spectrophotometer absorbs the heat from the lamp 2 and elongates by attaining the memorized state while the lamp 2 is lighted up and a tungsten lamp 4 is put out. On the other hand the shape memory alloy 12 on the lamp 4 side is not heated and therefore the shape memory alloy shrinks by attaining the free state. Then the lamp 2 and a supporting plate 6 supporting the lamp 4 turns in a direction A around a shaft 8 and the plate 6 stops in the position where the plate contacts with the shaft 16 by which the lamp 2 is set in the use position.

    Abstract: PURPOSE:To reduce the cost of a device, and to remove restrictions of an optical system and reduce an error by rotating or moving a half-mirror which has a small hole. CONSTITUTION:Luminous flux from a light source 2 or 4 is made into homogene ous light through the diffraction grating 16 of a spectroscope part 10 and the light is incident on a beam splitter 24 through reflecting mirrors 18, 20, and 22. The splitter 24 is composed of the half-mirror formed by boring numbers of small holes in a mirror or by forming a film with numbers on small holes on a base material which is transparent to ultravoilet visible light, and the splitter is rotated by a motor 26. Namely, an image of the small holes moves on a sample and detectors 42 and 44, so substantially no image of the small holes is formed. The incident light is split by the splitter 24 continuously into sample light 28 and reference light 30, which are incident on the detectors 42 and 44 through the sample cell 38 and reference cell 40 in a sample chamber 36 and detected respectively, so that a measuring circuit calculates the transmissivity or absorbance of the sample.

    Abstract: PURPOSE:To reduce the memory capacity of data to enhance economical efficiency, by a method when the unidirectional count value distribution data stored and constituted in a memory circuit at every rotary angle is read out to perform image re-constitution treatment and the two-dimensional distribution image of the radiation incidence count value on a detection surface is reconstituted. CONSTITUTION:The rotations of a collimator 1 and a detector are controlled by an electronic calculator 7 and only the signal X among position signals X, Y obtained at every rotary angle is stored in the memory circuit 8 in the electronic calculator 7 along with an angle signal while being sending to said memory circuit 8. The memory circuit 8 is equipped with the memory region of an angle theta and the memory region corresponding to each of positions X1, X2, X3,... in the X-direction and both signals are successively stored to count the number of development times at every position. The X-direction unidimensional distribution data of this radiation incidence count value is stored along with the angle theta thereof. After the data are stored, these data are read out to be measured as projection data and operation treatment such as convolution or back- projection for re-constituting the two-dimensional image is performed from the projection data by the operation apparatus 9 in the electronic calculator 7 to regenerate the two-dimensional distribution image of the radiation incidence count value.
