Abstract: PURPOSE:To stabilize the evaporation speed for a long period and to form uniform film by deflecting the electron beams generated with a hollow cathode by the magnetic field generated with an electromagnet, and heating and evaporating an evaporation material while scanning and irradiating the surface of the evaporation material. CONSTITUTION:The crucible 12 receiving the evaporation material 7 and a base plate 8 to be treated are oppositely disposed in a vacuum vessel 13 evacuated into vacuum. The electron beams 1 generated by the electric discharge through a hollow cathode 6 irradiates the evaporation material 7 to heat and evaporate.

Abstract: PURPOSE:To unify a light source light quantity between respective detecting starting time points and to remove a detecting error by being equipped with a zero cross pulse generating circuit to detect the zero cross timing of an alternating current power source, and starting the detection of the photodetecting quantity of a solid-state image pick-up element with the same period as the pulse output period. CONSTITUTION:A zero cross pulse generating circuit 2 generates a pulse in zero cross timings t0 and t2 of an alternating current power source. A delaying circuit 6 a supplies delaying signal to delay the pulse only by t1-t0 to an AND gate 7. A CPU 8, in times t3-t8, supplies a shift pulse control signal to the AND gate 7 and the gate 7, in t3-t8, when a delaying signal is inputted, feeds a shift pulse P1 to a CCD line sensor 1. Consequently, the pulse P1 synchronizes with the zero cross pulse. The circuit 2 detects the zero cross timing of an alternating current power source, and therefore, the period of the ripple of the light of a lamp 22 is also coincident with the period of the zero cross pulse. Consequently, the period of the shift pulse to the sensor 1 is coincident to the period of the above-mentioned ripple. Consequently, during respective detecting starting timings of the sensor 1, the light quantity of the lamp 22 comes to be constant.

IPC: F01N11/00
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To measure a concentration of a gas of a plurality of components accurately in a simple constitution. SOLUTION: The gas sensor has component gas-measuring parts 4, 5 set corresponding to component gases (HC, NOx) to be measured at a gas passage 1b. The gas to be measured is introduced to the gas passage 1b. An oxygen concentration is controlled to be constant at the gas passage 1b by oxygen concentration-controlling parts 2, 3. The component gas-measuring parts 4, 5 have oxygen pump cells 14, 41, 51, 52 which move oxygen between the gas passage 1b and a duct 1c to which the air is introduced. A concentration of each component gas is measured from a change of pump currents. The electrode 41 is constituted to be active to HC of small stability and inactive to NOx of large stability and arranged at the upstream side. The electrode 51 is constituted to be active to NOx and arranged at the downstream side.  Therefore, HC is not oxidized which causes a measurement error at the electrode 51 where NOx is reduced.

IPC: H01F7/08
Filed: 1990-04-14
Abstract: PURPOSE:To obtain a compact 4-axis attitude controller by providing a movable coil block obtaining by putting two pairs of square coils combined in a cross on each other and a square columnar magnetic circuit block and supplying a prescribed current to each coil based on the output of the position detection means. CONSTITUTION:A coil block 1 is obtained by putting two pairs of square coils combined in a cross on each other. In a square columnar magnetic circuit block 2, three movable slits 3a - 3c into which the coils 1a - 1d of the block 1 are put are formed in the axial direction of a side face and therefore the magnetic field is set in the axial direction in each slit. As a result, the block 1 can freely change its attitude in four degrees of freedom by the Lorentz forces generated at the coils 1a - 1d with the prescribed current supplied to each coil based on the outputs of the position detection means 4a - 4d. Thus the constitution of a 4-axis attitude controller is simplified together with an overall compact structure.

Abstract: PURPOSE:To enlarge the capacitance of a capacitor and do etching for formation of a lower electrode under gentle condition by forming the conductor film to become the lower electrode of a stack capacitor so that the step coverage may deteriorate. CONSTITUTION:By forming an interlayer insulating film 8 so that it may cover the work lines WL1-WL4 which constitute the gate electrodes of a MIS transistor, and then removing specified parts, contact holes C1 and C2 for the lower electrodes of stacked capacitors are formed. Next, the conductor film 9 to become the lower electrode of a stacked capacitor is formed so that the step coverage may deteriorate, and the conductor film 9 is patterned, whereby the lower electrode is formed. For the conductor film 9, the thickness enlarges above the step parts by the work lines WL1-WL4, and the thickness becomes small at the bottoms of these steps, so not only the capacitor of large area is formed at the sidewall of the lower electrode, but also it becomes such structure that the capacitor curves at a sharp angle from the top of the sidewall of the lower electrode to the bottom, whereby the capacitance of the stacked capacitor can be enlarged enough.

Abstract: PURPOSE:To provide an inexpensive document processor allowing a user to easily observe a character-entering column and capable of using an input document having high degree of freedom without restricting the array, described contents, or the like of each character-entering column and accurately extracting and recognizing the character information of an input document inputted by a scanner. CONSTITUTION:By using an input document 1 writing a background on a character- entering column with a color to be sensed by a scanner in a facsimile 100 the character-entering column can be clarified. The character information of the document 1 is inputted from the facsimile 100, and prior to the recognition of characters by a character recognizing part 104, a character-entering column detecting part 103 detects the character-entering column from the background area, removes the background and accurately extracts the character information, so that normal recognition can be attained. Consequently, monochromatic printing can be attained and the cost of a document can be reduced. Thus, it is unnecessary to use a specific means or a character-entering frame for indicating the position of a character entering column and the degree of freedom in the arrangement of a character-entering column or described contents such as the explanation of an input document can be improved.
