摘要： An optical CT apparatus 10 is mainly composed of a container 12 filled with an optical interface member 20; a light-projecting section, comprising a light source 22 and an optical switch 24, for projecting light into the container 12; a light-detecting section, comprising photodetectors 30 and shutters 32, for detecting the light from the inside of the container 12; and an arithmetic/control section 14 for calculating a spatial distribution of absorption coefficient. The arithmetic/control section 14 has a function of determining a spatial distribution of a characteristic amount concerning a part of an object to be measured 200 according to a comparison of an optical intensity signal actually measured by each detector 30 in a state where the container 12 is filled with the optical interface member 20 with an optical signal actually measured by each detector 30 in a state where the optical interface member 20 is partly replaced by the part of object to be measured 200.

摘要： The present device is equipped with a measurement site holder 3 that is constructed using a negative impression of the measurement site 10. As a result, variation in the measured values caused by the non-uniform distribution of components in the measurement site 10 is reduced, so that variation in the measured values caused by variations in the light path length accompanying variations in the shape of the measurement site 10, and by variations in blood flow or the like that accompany differences in the contact pressure, can be reduced. Since living-body information and measurement parameters for the patient are recorded on a recording medium 11 mounted on a measurement site holder 3 for the exclusive use of the individual patient, the erroneous acquisition of living-body information for individual patients can be prevented, and reproducible measurements can be performed.

摘要： The present invention intends to provide a shift control apparatus for transmission which can reduce or prevent the speed-change shock and/or noise at the balk point where the sleeve engages with the ring in the shift push-in process. In order to achieve the above object, a shift control apparatus for a transmission comprises a plural sets of paired free-rotate gears, a plural sleeves 17, 18, a plural sets of paired synchronize rings 27 to 29, an actuator 65, 70 for actuating the sleeve, a control means 50 for controlling the actuator based on a speed-change command. The control means 50 controls the actuator 70 so that the sleeve 18 is driven by a first drive force Qmax upon starting of a speed-change operation, and is driven by a second drive force Q2 smaller than the first drive force at least during a first time period T3′ to T4′ from a time before a balk point B of the sleeve where the sleeve engages with the synchronize ring in a shift push-in operation.

摘要： An arithmetic control mechanism of the present optical CT apparatus calculates first light densities in output portions of an object on the basis of a numerical analysis method, when it is assumed that the object is divided into fine segments and all segments have the same value as an absorption coefficient under predetermined conditions equivalent to an actual measurements; and calculates second light densities in the output portions on the basis of the method, when it is assumed that sequentially selected one of the segments has a specific value as an absorption coefficient under the predetermined conditions. Further, the mechanism calculates, as influences of the segments, ratios of the first to the second light densities, thereby obtaining an influence matrix corresponding to an arrangement of the segments; calculates relative ratios of the third light densities in the output portions on the basis of the actual measurements to the fitst light densities, thereby obtaining a relative ratio matrix corresponding to arrangements of input and output portions of the object; and performs a matrix calculation by using the influence matrix and the relative ratio matrix, thereby obtaining feature data of the segments for reconstructing a tomographic image of the object.
