IPC: H04N7/18
Filed: 1985-12-02
Abstract: PURPOSE:To obtain a correct thermal image without being affected by emissivity, by utilizing an image data obtained using two kinds of wavelengths. CONSTITUTION:To obtain an energy Wlambda1 with a wavelength lambda1 and an energy Wlambda2 with a wavelength lambda2, a filter 1 is switched to store the energies with the wavelength lambda1 and lambda2 transmitted through the filter 1 into frame memories 4a and 4b respectively. Then, a processing is done with a comparison operational unit 5 at each pixel of the memories 4a and 4b and from the results thereof, the energies are converted into correct temperatures at a temperature converter section 6. After written into a frame memory 8, the processed data is read out through a control of a microcomputer 12 and fed to a monitoring unit 10 through a processing unit 9 to be displayed. This assures a correct thermal image even when the emissivity is not even over the entire surface of an object.

Filed: 1985-11-30
Abstract: PURPOSE:To eliminate the influence of a transient response to be inflicted upon the output of a sample holding circuit by nearly equalizing a switching output signal when a switching device is switched between a mode wherein an input signal is held and a mode wherein a signal is inputted following up the input signal. CONSTITUTION:The intensity P1 of the projection output of a semiconductor laser 1 is stabilized with output intensity under automatic light output control during information reproduction or increased to high output intensity during information recording and erasure. This is converted by a photodetector 2 into a signal Va1, which is compared with a reference voltage Vb1 to output a signal Vc1. At this tiem, the sample holding circuit 4 operates under the control of a switch timing signal S2 to perform the automatic light output control according to the voltage Vc1. Then, data Ve1 on low output intensity during reproduction is stored in a memory circuit 6 during recording according to the signal S1. Then, a switching circuit 7 is switched according to the negative progress trigger of the switch timing signal S2 to pass the output of the circuit 6. Then, the output Ve1 of a circuit 4 which is outputted through an LPF 5 has no transient response. Therefore, no transient response appears at the laser 1.

IPC: A61M5/152
Filed: 1989-10-18
Abstract: PURPOSE:To lessen the rupturing of a balloon during holding of a liquid chemical and to allow the injection of the liquid chemical in the balloon at nearly a specified rate into a patient by using the balloon which is subjected to a pretreatment to remove a part of energy elastic force from the stress of a linear elastic hysteresis curve. CONSTITUTION:The balloon 3 is formed by removing a part of the energy elasticity from the stress in the balloon part consisting of an elastic material and is produced by packing liquid or gas into the balloon consisting of the untreated elastic material to the intended packing volume of the liquid chemical or above and subjecting the material to the pretreatment to hold the expanded state of the balloon for >=1 hours by removing a part of the liquid or gas. Since the stress at the expansion of the balloon is smaller than the untreated balloon, the rupture during holding of the balloon is lessened. The hysteresis formed by the stress-strain curve, i.e., the area formed by the stress curve and the strain curve is smaller as compared to the untreated balloon and, therefore, the liquid chemical in the balloon is injected into the patient by maintaining the specified rate and the maintaining of the balloon during the expansion at the specified shape is possible.
