Title: Liquid-nitrogen detecting element and liquid nitrogen detector
Inventor: TODA YASUSHI
IPC: G01N27/04
Filed: 1987-05-26
Abstract: PURPOSE:To make it possible to perform very stable operation and to improve reliability, by utilizing transition between superconductivity and normal conductivity, and detecting discontinuous change in resistance value. CONSTITUTION:A main body part, which comprises a material having the transition temperature of superconductivity within the range of nitrogen liquefaction temperature of -147.1--195.8 deg.C, is provided. Terminal parts for electrical connection are provided. The inside of a Dewar flask 4 is filled with liquid nitrogen 6. Then, the liquid level rises up, and a detecting element 3 is immersed in the liquid nitrogen. The normal conducting state of the element is changed into the superconducting state, and the resistance value of the element is decreased. Therefore, a voltage across an output resistor 5 is changed, and an output voltage is yielded in an amplifier 2. In this way, the liquid level of the liquid nitrogen is detected. In order to make the transition possible, it is practical that the superconductivity transition temperature of the main body of the detecting element is made to be -141.7--195.8 deg.C, which is the temperature where nitrogen is liquefied.

Title: Magnetic data reader
Inventor: SEZAI HIDESHI
IPC: G11B20/14
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To prevent the erroneous recognition of waveform widths by spuriously converting three kinds of the waveform widths obtd. at the time of magnetic recording data reproducing by an MFM system to the min. waveform width which is a reference. SOLUTION: The three kinds of the waveform widths of 2:3:4 outputted according to the data of recording on a magnetic information recording medium C from a signal forming circuit 1 by the start of data reading is detected by a detecting circuit 2a. A data processing circuit 2b multiplies the waveform widths 3, 4 by 1/2 and converts the same to the spurious waveform width 2. When the waveform width 2 attains the prescribed value, the reading of the data is executed with the average value as a reference value (a). The waveform width 2 is decided when the waveform width is 1/4 to 5/4 of the reference value, the waveform width 3 when 5/4 to 7/4 and the waveform width 4 when 7/4 to 9/4.  When the data reading exceeds a prescribed number of pieces, the first waveform width is excluded and the average value of the waveform width 2 adding the excess waveform width is determined and if the value is 7/8 to 5/4 of the reference value a of the previous time, the data is read by determining this value as the fresh reference value.

Title: Surface treatment of electrophotographic sensitive body
Inventor: NARUKAWA SHIRO
IPC: G03G21/00
Filed: 1987-05-25
Abstract: PURPOSE:To enable stable copying without generating image flow even under high-temp. and high humidity conditions by supplying hydrophilic powder to the surface of a photosensitive body. CONSTITUTION:The hydrophilic powder is supplied by spraying, blowing, etc., to the surface of the a-Si photosensitive body in order to interpose a material having water absorptivity in the surface of the photosensitive body so that moisture is adsorbed on the surface by said material. The hydrophilic powder includes powder of ceramics, powder of an Si compd., etc. The smaller grain sizes of the powder are more preferable. The surface area of the powders of the same weight increases and the water absorptivity increases if the grain size is reduced. The supply of the hydrophilic powder is executed by a method of supplying the powder via a cleaning roller, a method of previously incorporating the hydrophilic powder into a toner at need, etc. The generation of the image flow even in the continuous copying under at and under the high temp. and high humidity (for example, atm. temp. - 30 deg.C, relative humidity - 85%) is thereby prevented.

Title: Projection exposing device
Inventor: MIZUTANI HIDEO
IPC: G03F7/20
Filed: 1994-06-09
Abstract: PURPOSE:To make wafers to be hardly affected by the abberation of a projection optical system and, at the same time, to continuously align the wafers with a scanning direction at the time of exposure. CONSTITUTION:A wafer is exposed to the pattern of a reticle by using a scan exposing system by synchronously scanning the wafer in +Y direction and the reticle in -Y direction. By continuously forming grid-like marks 17 near the shot area of the wafer along the scanning direction and other grind marks in an area on the reticle nearly corresponding to the shot area in the scanning, the positional deviations between the two rows of grid-like marks are continuously measured. At the time of measurement, the two measuring directions 38 and 39 of the marks 17 are symmetrically set with respect to a straight line 37 connecting the center 36Aa of a detecting area with the optical axis AX of a projection optical system. Therefore, the abberation and image forming magnifications in the two directions 28 and 39 become equal to each other.

Title: Plant monitoring controller
Inventor: INOUE TOSHIAKI
IPC: G05B23/02
Filed: 1982-07-23
Abstract: PURPOSE:To adjust easily and efficiently a digital controller, by transmitting the operation logic of the digital controller as data to a computer from the digital controller and discriminating the validity of this logic on the computer side. CONSTITUTION:Digital controllers 100-110 which receive the transfer request from a computer 30 transmit contents of their own logic parts from transmitting devices 102-112. When receiving contents of logic parts and check sum data, the computer 30 stores them in a pertinent memory and checks received data to discriminate the validity of data. If this checked data has abnormality, the computer 30 transmits the transfer request of logic again. If data is normal, the computer permits and confirms the restoration of controllers to on-line. The operator uses a keyboard 33 to permit it. The control of controllers is transferred to intrinsic processing logics; and when check of the display request is requested, data is preserved in a memory and is transmitted.

IPC: G06F3/0488
Filed: 1993-04-30
Abstract: PURPOSE:To read the shape of a three-dimensional object as digital data which can be processed graphically by providing advancing and retreating probes which are retreated when they are pressed against an object and detecting the moving amounts of the probes, and then, replacing the ruggedness of a measuring area with picture data based on the moving amounts of the probe. CONSTITUTION:When a ruggedness sensor 10 is brought into contact with the surface of an object, the front ends of advancing and retreating probes 12 are pushed in accordance with the shape of the object and each probe 12 retreats in accordance with the external surface of the object. The retreating amounts of the probes 12 can be discriminated from the number of light intercepting line crossing times of light from a light emitting element arranged in accordance with the probes 12. The number of light intercepting line crossing times is measured and counted by means of a photoreceptor element and moving amount detecting device 20. The device 20 or a data processor 30 calculates the moving amounts of the probes 12 in accordance with the counted number of times. When the moving amounts are calculated, a picture data preparing section performs a picture preparing process based on the ruggedness of the object at each point and outputs the processed results to a picture displaying device as a three-dimensional picture.
