IPC: G06K9/36
Filed: 1979-04-12
Abstract: PURPOSE: To make a handwritten manuscript easy to read by reforming characters on the handwritten manuscript and its slanting lines through simple circuit constitution.  
     CONSTITUTION: Frames are written for every lines of handwritten manuscript 1 and while those frames are detected by frame detecting circuit 4, scanning circuit part 3 takes a scan to store picture elements of characters, scanned by the circuit part 3, in the 1st memory circuit part 6. The picture elements stored in this circuit part 6 are read out in the direction perpendicular to the write direction and then stored in the 2nd memory circuit part 8. When the picture elements are read out from this circuit part 6 and transferred to memory circuit part 8, inter-gap detecting circuit part 5 detects an interval between characters to consider picture elements up to where no element resides exceeding the character interval to be one character, and virtual center line detecting circuit part 7 detects the virtual center line of the character and reforms characters handwritten on manuscript 1 and its slanting lines to make handwritten manuscript 1 eacy to read, thereby printing characters out by print part 9.

Filed: 1987-02-27
Abstract: PURPOSE:To automate an analysis by a sequence controller by providing a means for detecting the formation of filamentary plasma and controlling on and off, etc., of a filamentary plasma inducing means by the detection signal thereof. CONSTITUTION:This instrument is so constituted that the formation of the filamentary plasma (f) is detected by an impedance detector D which detects said formation by a change in the input impedance of a coil C wound on a plasma torch P. A plasma flame F by a torch P is then formed by the sequence controller 12 and after the impedance is matched, a sample is dropped into a sample receiver 4 and the sample is dried by a heater 5. A Tesla coil T is thereafter operated to generate corona discharge from the receiver 4. Plasma (f) extends from the flame F and arrives at the receiver 4 when the formed ions arrive at the flame F. The plasma evaporates the sample at the tip of an electrode 3 and supplies the vapor thereof to the flame F. The formation of the plasma (f) is detected by the detector D and the operation of the coil T is stopped. Spectrophotometric measurement by a measurement circuit 11 is then executed.

Title: Call signal transmitting circuit for wire radio exchange
Inventor: WATANABE MASAAKI
IPC: H04M3/02
Filed: 1988-02-29
Abstract: PURPOSE:To simplify an individual signal tuning circuit by identifying the call in one and the same line and the call in an other line in case of mutual calling between subscribers, varying the gain of a signal amplifier section so as to make the individual call signal received by a telephone set of a called party the same independently of the call in one and same line and the call in the other line. CONSTITUTION:In order to make a signal level at a call other line the same as a call in one and same line, a contact 5 of a relay 4 is closed based on a discrimination signal from a control section 9 so as to decrease the gain of a signal amplifier section 3 at other line call thereby matching the call level of a telephone set 10. Thus, the discrimination signal outputted from the control section 9 is used as a same line/other line control signal, the signal activates the relay 4 to control the cal signal level. Thus, it is possible to make the call signal level at a terminal of each telephone set 10 even in an other line call and in one and the same line call and the individual signal tuning circuit is simplified.

Title: Infrared sensor element and it's manufacture
Inventor: MORI TAKETOSHI
IPC: G01J1/02
Filed: 1990-02-27
Abstract: PURPOSE:To make a subminiature and highly precise element which can perform a rapid temperature measurement by laying bridges on which infrared sensors are mounted over a groove section formed on a substrate in advance. CONSTITUTION:Four parallel bridges 7 are laid at nearly regular intervals over a groove section 2. Each of the bridges 7 is an insulated layer 6 which was originally formed on an area other than the groove section 2 of a silicon substrate 1 and which was extended over the groove section 2 and is composed of three layers; silicon oxide 3b, silicon nitride 4b and another silicon oxide 5b. Each of the bridges 7 is 3.3mum in thickness, 60mum in width and 2mm in length. Each of the bridges is extremely long in proportion to its thickness and width. Since the bridges 7 are multilayer-structured and are made of the plural number of material having complementarity, the strength of the bridges is raised. This can make the bridges long. The long bridges remarkably contributes to the improvement of a response sensitivity of an infrared sensor element.

Abstract: PURPOSE:To improve the higher carrier mobility by implanting an impurity such as arsenic (As) to both side faces of a buried layer made of an epitaxial growth part of a high mobility substance grown on a channel region, thereby weakening the potential barrier. CONSTITUTION:An epitaxial growth part of a high mobility substance is buried and selectively grown in the channel region 4 between the source region 2 and the drain region 3 of a silicon substrate 1, etched so that the gate electrode 5 on the region 4 is shorter than the channel region, with the etched gate electrode 5 as a mask an impurity ions of As, Se or S are implanted in a self-aligning manner to the both side faces of the buried part. Since an impurity implantation region 8 is formed on the both sides across the boundary region of the substrate 1 and the epitaxial growth part of the region 4, the effect of the potential barrier in the boundary region can be reduced.

Abstract: PURPOSE:To facilitate positioning by using a light beam with hard-to-expose wavelength different from the wavelength of a light used for exposure as a light beam to be projected upon an image sensor. CONSTITUTION:A mask with a pattern to be exposed is selected for a wafer 9. Then, the alignment mark 4b on the mask 10 is irradiated with a light beam and the code of the mask 10 is inputted on a keyboard. Consequently, the signal from the image sensor 26 is inputted to a control part 15 and the mask 10 is set at a specific reference position. Then, a filter 21 is set and the alignment mark 6 on a wafer 9 is irradiated with a light beam K with hard-to-expose wavelength difference from the exposure light beam passed through a filter 21. The signal from the sensor 26 is inputted to the control part 15 and the wafer 9 is set at a specific reference position.

Abstract: PURPOSE:To efficiently perform migration, by arranging a surface layer comprising an electric insulating substance, a heat conductive layer consisting of a plurality of heat conductive parts and a shape reinforcing and supporting plate layer in this order. CONSTITUTION:A gel mount stand 1 for electrophoresis is constituted so that a migration gel is mounted on a surface layer 4 in a closely adhered state to perform electrophoresis and the temp. of cooling water preset to each temp. is transferred to the steel plate 51 closely adhered to each steel pipe 52. This temp. is transferred to the migration gel mounted on the surface layer 4 in a closely adhered state from each steel plate 51 through the surface layer 4 to set an intended temp. gradient in the gel. Joule heat generated during migration is transferred to the surface of each steel plate 51 at the side of a support plate layer 6 through the surface layer 4 and further discharged to the outside of a gel mount part 2 from the entire surface of each steel plate 51 by water flowing through the steel pipe 52. Therefore, migration can be efficiently performed while the intended temp. gradient is held over the entire surface of the migration gel.
