Title: Image correcting device for scanning type electron microscope
Inventor: KAGAMI AKIRA
IPC: G06F19/00
Filed: 1987-07-29
Abstract: PURPOSE:To form a highly precise image oscillation distortion correcting device capable of estimating the oscillation regardless of the size of the amplitude of the scanning oscillation by utilizing the property not depending on the oscillation amplitude of the two-dimensional alignment of the correlation values as a basis when estimating the scanning oscillation in the scan vertical direction based on the correlation information of an image scanning line piece. CONSTITUTION:Mutual correlation values determined over multiple lines using an image line piece, i.e., two-dimensional alignment data determined by the line number and the distance between lines, are sorted for each line number, individual data are weighted by the function of the distance between lines to determine the addition value, and the scanning oscillation in the scan vertical direction is estimated from the addition value. The data constituting the correlation value pattern are sorted for each line number, the addition value with the plus or minus symbol of the relative line number for individual data reflects the phase of the oscillation. This addition value can also reflect the amplitude information of the oscillation. The oscillation with any magnitude can be thereby estimated and corrected precisely.

Title: Photoetching
Inventor: AMANO HARUO
IPC: H01L21/30
Filed: 1987-07-27
Abstract: PURPOSE:To form an etched film so that it has uniform dimensions at a center part as a whole and manufacture fine integrated circuits, by making the exposure time of a photoresist at the peripheral parts of a semiconductor wafer different from the ones at the other parts, thereby giving selective etching to the etched film. CONSTITUTION:Peripheral parts 2A of a semiconductor wafer 1 are not exposed very much and then only weak exposure causes each resist to be in a state where its functions inefficiently and its extremely insufficient exposure is performed so that its state insures to result in a defective photoresist. Yet a center part is normally exposed. When its part is etched, as to dimension data regarding respective hips in the semiconductor wafer, the amount of scatter between center and end parts becomes small. There is a good reason to suppose that as the boundary to be etched extends to the sides of peripheral parts 2A, the etching conditions of end parts in the vicinity of the boundary between the center part 2 and peripheral parts 2A of etching approach relatively those of etching at most of center parts in the center part 2.

IPC: B29C45/50
Filed: 1995-06-30
Abstract: PURPOSE: To prevent generation of undershoot and overshoot of pressure at the time of switch of speed control to pressure control so as to perform continuous and stable control. CONSTITUTION: A pressure variation Pe between a pressure detection value Pd obtained by detecting an injection pressure and a preset desired pressure value Ps is obtained. A position change quantity ΔS of a position detection value Sd obtained by detecting a position of a screw 2 at a fixed time is divided by a pressure change quantity ΔP of the pressure detection value Pd at a fixed time so as to obtain a screw movement ds=ΔS/ΔP per unit pressure change quantity. Further, the variation Pe is multiplied by the screw movement ds so as to obtain a forecast movement Pe×ds, and a basic command value Vcp is generated based on the forecast movement Pe×ds. The basic command value Vcp is made to pass a speed limiter 3 where an upper limit value is previously set to a desired speed value Vs so as to obtain a speed command value Vc.

Title: Antenna device for measuring azimuth
Inventor: YASUJIMA AKIHIRO
IPC: G01S3/08
Filed: 1983-10-11
Abstract: PURPOSE:To measure azimuth with good accuracy and sensitivity by disposing plural antennas at an equal interval on a circumference and taking out of one transformer while changing over successively and cyclically two antennas as a set. CONSTITUTION:A pair of antennas 1, 2 at a space S is provided and a transformer 301 is connected thereto. The voltage corresponding to the phase difference between the two antennas is taken out to the secondary side output and the sum (phase sum) output of the two antennas is taken out of the mid-point on the primary side. When the antennas 1, 2 are rotated along the circumference, the phase difference output determined by the space S between the antenna is obtd. in proportion to the cos of the angle theta between the centers of the two antennas and the incoming direction of radio waves. The phase of the sum output is changed by about 90 deg. and is synthesized with the differential output in the same phase (or in the opposite phase) to determine a sense. In actuality, the antennas are arranged on the circumference and each pair of the antennas are cyclically and successively changed over by an antenna selector 401, by which the outputs of the difference and the sum are obtd.

Title: Follow-up system
Inventor: NOZAWA RIYOUICHIROU
IPC: G05B19/18
Filed: 1981-11-25
Abstract: PURPOSE:To prevent the shift of a machine even though a position control loop is changed to a close state from an open state, by carrying out the follow-up so that the steady deviation always remains at an error storage means. CONSTITUTION:When a position control loop is changed to an open state from a close state, the steady deviation B which is obtained immediately before the switching of the position control loop and stored in an error storage register 107b is preset to a steady deviation register 201. In an open state, a follow-up arithmetic circuit 203 subtracts the difference between errors A and B stored in the register 107b from the contents AP of a present position register 202. Thus the position of a machine is renewed. An arithmetic circuit 204 performs an operation of -(A-B)=D. The machine moves by an external command, and m1 units of feedback pulses FP are produced. Thus the contents of the register 107b are set at -(B+m1), and the register 202 is renewed to AP+m1. A command of -(B-B)=m1 is given to a pulse distributor 103, and the register 107b is set at -B. Therefore the machine has no shift thereafter even though the position control loop is changed to a close state from an open state.

Title: Semiconductor acceleration sensor
Inventor: NODA SHUJI
IPC: G01P15/12
Filed: 1987-07-28
Abstract: PURPOSE:To obtain a low-cost sensor which allows the thickness of its epitaxial layer to be set freely by using a single crystal substrate having no epitaxial layer and controlling the thickness of a beam through two-stage etching and end point detection by an infrared sensor. CONSTITUTION:The n-type silicon substrate 1 having no epitaxial layer is oxidized thermally to cover the surface with an oxide film 2. Then this oxide film 2 is board, and p-type impurities are implanted only in the holed part to form a gauge resistance diffusion layer 3. Then a nitride film 5 is formed as a final protection film by plasma CVD while a diffusion gate is brought into contact with Al wiring 4. Here, a pad part 10 and an etching part 7 are holed, a silicon etching liquid whose etching speed is not so fast is used first for etching, and the silicone etching liquid is used for etching from the reverse surface. Thus, the two-stage etching is performed and when a hole penetrates a wafer, light from the infrared sensor is absorbed by wax and its reflected light attenuates to enter an off-mode; and thus an end point is detected and the sensor whose initially provided step is held as thick as the beam is obtained.

Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To shorten a time necessary for exposure/transfer and to improve a throughput, as for an aligner. SOLUTION: The aligner 1 is provided with an illuminating optical system 3 for forming a luminous flux L1 emitted from a light source 2 to a prescribed shape and illuminating an original plate 4 on which a circuit pattern is formed, and a projection optical system 8 for projecting a luminous flux L2 transmitted through the original plate 4 to a photosensitive substrate 7. In this case, the original plate 4 is held by a rotary stage 5 capable of correcting the relative rotational deviation between the original plate 4 and the photosensitive substrate 7, besides, the illuminating optical system 3 includes rotating means 35 and 36 for rotating the luminous flux with the prescribed shape for illuminating the original plate 4 so as to correct the rotational deviation with reference to the exposure area on the original plate 4.  Thus, the structure of a stage for placing the photosensitive substrate 7 is simplified and made light in weight, and also the positional deviation at aligning is easily corrected.

Title: Head base drive control mechanism in automatic answering telephone set
Inventor: HASHIMOTO KAZUO
IPC: G11B15/10
Filed: 1984-09-11
Abstract: PURPOSE:To improve the performance of a head base drive control mechanism and to save power consumption by adopting the constitution that a head base of a response tape is not directly pressed and moved but via a switching sliding member by the shaking of a main lever. CONSTITUTION:In listening a message recorded on a reception tape during absence, an operation button for reception tape reproduction is operated, a pulse current is applied long to a solenoid 7 by a control circuit to move a switching slide member 52 to the left non-operating position. Then a cam gear is turned clockwise. On the other hand, the main lever 50 is turned counterclockwise around a shaft 35 by the 1st cam 4g, but since the sliding member 52 is moved to the left, a projection 50h of the main lever 50 does not engage with a cut and rise part 52a and the member 52 is not pushed up. Since even a folded part 52d of the switching slide member 52 does not push the head base 2 upward, no response tape is run. Then the performance of the head base drive control mechanism is improved, an irrational force is exerted on the main lever and the power consumption is saved.

IPC: H04N9/04
Filed: 1983-10-07
Abstract: PURPOSE:To remove an interfering signal without deteriorating vertical resolution by removing the interfering signal in a luminance signal zone when there is the level difference of luminance signal in each horizontal scanning period and there is no change of horizontal amplitude. CONSTITUTION:A horizontal end part detecting circuit 41 detects a signal corresponding to amplitude change (edge part) in the direction of horizontal scanning line of a luminance signal and supplies to a full-wave rectifier circuit 42. The full-wave rectifier circuit 42 converts horizontal edge signals in positive and negative directions into one directional signals and supplies them to a switch circuit 43. Vertical relative error signals of luminance signals and color difference signals are supplied to the switch circuit 43. When a horizontal edge signal is present, above-mentioned vertical relative error signals are cut off, and when there is no horizontal edge signal, this is conducted and supplied to a horizontal aperture compensating circuit 27 as controlling signals. Thus, interfering signals in a luminance signal zone generated by vertical relative error are removed.
