An ink jet printer connected to a personal computer and normally driven by a PC battery accommodated in the personal computer. The ink jet printer detachably accommodates therein an auxiliary battery. The printer has a control portion and a driving portion for moving a print head. If a voltage level of the PC battery becomes less than a threshold voltage during printing operation, the electrical connection between the PC battery and the control portion is maintained, whereas a power source to the driving portion is switched from the PC battery to the auxiliary battery. After the printing operation is completed, a power source to the control portion is switched from the PC battery to the auxiliary battery.

In order to generate a two-dimensional image of a sample in a short time using THz waves, provided is a reflective imaging device including a sample holder, a THz wave light source, a THz wave camera, a rotation mechanism for rotating the holder and the camera, and a processing unit. A sample unit includes an incidence member, a sample, and a reflection member. The sample includes a first region of only a membrane and a second region including a biopolymer. The camera detects, with regard to respective incident angles, a THz wave in which interference occurs between a component reflected at an interface between the incidence member and the sample and a component reflected at an interface between the sample and the reflection member, of each portion of the sample unit, and outputs a signal. The processing unit specifies an incident angle at which a signal of a first THz wave that interferes in the first region is relatively small and a signal of a second THz that interferes in the second region is relatively large, and generates a two-dimensional image of the sample based on the signal from the camera with regard to the specified incident angle.

A desulfurization device releases exhaust gas into the atmosphere without reduction in CO2 recovery rate and without mercury components. Because the absorbent of the desulfurization device is drawn from an absorbent reservoir by a circulating pump and sprayed through spray nozzles into a desulfurization-absorption unit and is mainly circulated outside the wall of a water seal tube by a stirrer in the absorbent reservoir, the flow of the absorbent that falls from the desulfurization-absorption unit into the water seal tube flows in a single direction from top to bottom and hinders the ascension of gas bubbles. Intermixing of the gas for oxidizing the sulfur dioxide with the desulfurization device exhaust gas is thereby prevented, efficient CO2 recovery is possible without reduction in the CO2 concentration recovered from the exhaust gas after desulfurization and mercury in the combustion exhaust gas is absorbed in the absorbent of the desulfurization device.

A color identifying device includes a mount block, a color detector, a lens and a color identifier. A reactive board having a plurality of surfaces to be measured in respective predetermined positions is mounted in the mount block. The color detector has a plurality of color measuring areas corresponding respectively to the reaction surfaces of the reactive board mounted in the mount block. The lens forms images of the surfaces of the reactive board mounted in the mount block on the respective color measuring areas. The color identifier identifies the colors of the surfaces based on output signals from the corresponding color measuring areas.

In a semiconductor integrated circuit device, a logic circuit section is provided at the top surface of a P-type silicon substrate and a multi-level wiring layer. The device is further provided with a temperature sensor section in which a first temperature monitor member of vanadium oxide is provided above the multi-level wiring layer. A second temperature monitor member of Ti is provided at a lowermost layer of the multi-level wiring layer. The first and second temperature monitor members are connected in series between a ground potential wire and a power-source potential wire, with an output terminal connected to the node of both members. The temperature coefficient of the electric resistivity of the first temperature monitor member is negative, while that of the second temperature monitor member is positive.
摘要:
An infrared photosensitive area is constituted by an infrared ray absorbing part that is heated by infrared rays, a thermal detector that detects the temperature change of the infrared ray absorbing part, and electrodes that are electrically connected to the thermal detector. The infrared photosensitive area is held up above one surface of a substrate by supports. The electrodes of the infrared photosensitive area are electrically connected to contact pads on the substrate by wiring material that constitutes the support. A shield projects from portions of the infrared ray absorbing part other than portions that correspond to the electrodes. The contact pads of the substrate and the surfaces of the electrodes and the supports that are directed away from the substrate are covered by the shield with an interposed space. This configuration enables an increase in the fill factor of the picture elements of the thermal infrared detector and enables greater absorption of infrared light.

At a heat treatment temperature in a reducing atmosphere of Ar and H.sub.2, a precursory film of V.sub.2 O.sub.5 is reduced into a VO.sub.x film with the heat treatment temperature selected in a predetermined temperature range between 350 .degree. C. and 450.degree. C., both exclusive, to control a resistivity of the VO.sub.x film, where x is greater than 1.875 and less than 2.0. The VO.sub.x film is not susceptible to a metal-semiconductor phase transition inevitable in VO.sub.2 at about 70.degree. C. and is excellent for use in a bolometer-type infrared sensor. When reduced at 350.degree. C. and 450.degree. C. the resistivity and its temperature coefficient of the VO.sub.x film at room temperature are 0.5 and 0.002 .OMEGA. cm and -2.2% and 0.2% per degree Celsius.

摘要:
A method for producing a steel section by a rolling process including a rough rolling step, an intermediate rolling step and a finishing rolling step. The intermediate rolling step comprises water-cooling the flange portion of the rough-rolled steel section between rolling passes in the intermediate rolling step to cool the surface layer of the flange to a temperature not higher than 750.degree. C., and rolling the flange portion during recuperation of the surface layer of the flange at least one time between the rolling passes with a total draft not less than 20% and at an average rolling temperature not higher than 950.degree. C. and, after the finishing rolling step the outer surface of the flange is cooled at a cooling rate ranging from 0.5.degree. to 10.degree. C./sec depending on the thickness of the flange. Also the carbon equivalent of the steel is controlled. The advantage is that steel sections of various contours and dimensions can be produced from minimized varieties of steel compositions.
