Title: Method and equipment for measuring concentration of nitrogen oxide
Inventor: KUDO SHUZO
IPC: G01N27/416
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To detect a nitrogen oxide with high selectivity by employing a metal oxide containing a specified ratio or more of bismuth Bi expressed in terms of metal element at the gas detecting part of a sensor element. SOLUTION: A sensor element comprising a gas detecting part 7 and a measuring electrode 9 is contained in a measuring chamber 5. A metal oxide containing 50 at.% or more of Bi expressed in terms of metal element is employed at the gas detecting part 7. In addition to Bi, a less than trivalent metallic element and one kind or more of element selected from In and Sn, e.g. Ca, Sr, Ba, are preferably added. When these elements are added, resistance of the sensor element is decreased and variation of resistance can be detected easily in low temperature region while enhancing response and recovery characteristics. The gas detecting part 7 is preferably heated up to 200-400 deg.C by means of a heater 11 and since the sensitivity to a nitrogen oxide is high but the sensitivity to other kinds of gas is low within that temperature range, an especially excellent selectivity can be attained.

Title: Electrophotographic copying device with editing function
Inventor: KATSUMATA AKIO
IPC: G03G15/047
Filed: 1985-03-04
Abstract: PURPOSE:To eliminate the limitation of the quantity of shifting and to improve versatility by inhibiting a standard pattern toner image from being formed when it is decided on the basis of the quantity of shifting set by input shift information that the standard pattern toner image is expected to be transferred to recording paper before the standard pattern toner image is formed. CONSTITUTION:The shift information which indicates the transfer position on recording paper for a visible image corresponding to an original image is inputted by an input means to set the quantity DELTAx of shifting. then, a standard pattern (P sensor pattern) is installed a distance d3 before the front end of an original and a light image of this pattern is projected on the photosensitive body before the original image is scanned optically to form an electrostatic latent image. At this time, when DELTAx>=d3, the recording paper shifts until it is overlaid on the standard pattern image, so it is judged that the standard pattern toner image is to be transferred to the recording paper, thereby discharging electrostatically an electrostatic latent image formation part corresponding to the standard pattern by an eraser. Consequently, the limitation of the quantity of shifting is eliminated and the versatility is improved.

Abstract: PURPOSE:To ensure the conflict of requests received from plural external interface by storing these requests into a common table together with the timer value. CONSTITUTION:The trace data production mechanisms 11-1-11-n write the contents of the external process requests into a common table 4 together with the contents of a timer 5.

Then the part 3 checks the number of an interface part stored in a 2nd area 42 of the table 4 at the interval set by the contents of the timer value. The parameter information stored in the 3rd area 43 of the table 4 is delivered to the corresponding interface parts 1-1-1-n for the simulation of the external process requests. In such a way, the requests received plural external interfaces are carried out by allowing these requests from plural external interfaces to be conflicted.

Title: Discriminating method for reference position of magnetic head
Inventor: YOSHIMARU TOMOHISA
IPC: G11B5/55
Filed: 1980-04-01
Abstract: PURPOSE: To discriminate the reference position of a magnetic head accurately by discriminating the reference position on the basis of the prescribed phase of a step motor after defecting the arrival of the magnetic head moving at right angle to a track, to the circumference of the reference track.  
     CONSTITUTION: Head 3 moves down at right angle to the track of a tape through step motor 2 and when it comes close to reference track 1a, microswitch 4 is closed through head 3, so that control circuit 5 will defect this arrival. On the basis of the prescribed phase position of motor 2 after this detection, the positioning of head 3 at the reference position opposing to track 1a is discriminated. Therefore, the reference position of the magnetic head is securely discriminated without being affected by the variance of switch 4, etc.

IPC: G09G3/18
Filed: 1983-03-17
Abstract: PURPOSE:To record an electron microscope image with high resolution by irradiating high polymer liquid crystal with an electron beam directly. CONSTITUTION:The high polymer liquid crystal is used while enclosed in a proper cell. This cell consists of, for example, two protection films 3 and 4 sandwiching the liquid crystal 1 from above and below, a spacer 5, and an external frame for fixing them.

This conductive coating 2 contacts the high polymer liquid crystal 1 and is earthed to the external frame by conductive resin material. When the high polymer liquid crystal 1 is irradiated with an electron beam, the transition of the liquid-crystal structure occurs, which is utilized to record an electron microscope image with high resolution.

Filed: 1993-03-04
Abstract: PURPOSE:To attain a desired intermediate potential within an operation period by receiving the detected potential level of a data output terminal and controlling the potential level of an output terminal according to the detected potential level. CONSTITUTION:An intermediate potential setting circuit 1 operates for a period in which a low level is inputted to a terminal 51 from the outside. At this time, the output of a NOR circuit 5 becomes a high level, and a NOR circuit 13 and a NAND circuit 14 are activated. The output levels of the circuits 13 and 14 are determined by the level of a data output terminal 52, and at the same time, an input level just before is held by a latch circuit 6 and is outputted. When the output of the circuit 6 is a high level, a NOR circuit 8 is activated, its output is determined by the level of the data terminal 52, and a NAND circuit 10 is not activated. Also, when the output of the circuit 6 is a low level, the circuit 10 is activated, its output is determined by the level of the terminal 52, and the circuit 8 is not activated. Then, since the operation of the circuit 1 can be controlled by the level of a terminal 2, a desired intermediate potential can be attained within an operation period.
