IPC: G05D3/12
Filed: 1987-06-05
Abstract: PURPOSE:To avoid the shift of position due to the variance of the working position of a limit switch and to perform the position control with high accuracy in a simple way, by switching automatically the position which is shifted by an extent equal to a half cycle of a zero marker signal to an original point confirming position in case the position where the limit switch is turned on is set close to the original point confirming position of the zero marker signal. CONSTITUTION:The position pulse signals (c) are counted by a computing element 1 of a position controller for a period during which a zero marker control signal (b) is set at '1' after a limit switch 7 is turned on and also calculates a distance (d) moved in said period. At the same time, a setting device 2 sets an optional distance A that can cover the variance range of the working position of the switch 7 in a distance shorter than that moved in a single cycle of the signal (b). Both distance A and (d) are compared with each other by a comparator 3. Then an FF 5 is set with d<A and then reset with d>A respectively. The signal valid and invalid states are switched by a switch 4 between the set and reset modes.

Title: Low frequency correction circuit
Inventor: SATOU TAKESHI
IPC: H04R3/04
Filed: 1984-07-05
Abstract: PURPOSE:To execute the low frequency correction automatically and to improve a low frequency reproduction ability by detecting the frequency of a point where a low frequency sound pressure of a sound pressure frequency characteristic in a speaker drops and a number of peak points of a frequency characteristic of an impedance. CONSTITUTION:A sweep signal is oscillated in an oscillator 2 by a command signal from a microcomputer 5 and supplied to a main amplifier 1. Then a current for flowing to a speaker 7 from the amplifier 1 is detected by an impedance detection circuit 6, and the detected result is converted into a digital signal by an A/D converter 3 and supplied to the microcomputer 5. The current for flowing in the speaker 7 varies inversely as the impedance of the speaker 7, and a characteristic of a current value shows the impedance characteristic of the speaker 7. With the aid of the impedance characteristic inputted to the microcomputer 5, by the covertor 3 the frequency with respect to a peak point frequency f0 of the impedance and a number of f0s are checked, thereby controlling a variable filter 4. The microcomputer 5 obtains a correction frequency characteristic from the detected result of the impedance characteristic, and the precise correction can be possible accordingly.

Title: Control device for lockup clutch incorporated in torque converter
Inventor: HATTORI TORAO
IPC: F16H45/02
Filed: 1987-06-05
Abstract: PURPOSE:To prevent damage due to slippage at the time of high-speed running by supplying oil pressure corresponding to a car velocity to a lockup clutch incorporated in a torque converter when it reaches a designated car velocity. CONSTITUTION:A spool 40 of a pressure regulating valve S1 of a lockup clutch control device S is moved to an equilibrium position with a spring 42 due to a pressure difference between line pressure PL from a hydraulic control valve Q and governor pressure PG introduced into an oil chamber 41. Line pressure corresponding to such displacement is partially returned to a reservoir 30 through an orifice 43 and a passage 44. On the other hand, when it reaches a preset car velocity, a spool 45 of an on-off valve S2 is moved to the left by the equilibrium among a pressure drop, the governor pressure PG and a spring 46 to supply pressure corresponding to the car velocity to a lockup clutch 2a of a torque converter 2. Thus, when the clutch is connected, mechanical efficiency and fuel cost can be improved, a shock at the time of low-speed running is softened by temporary slippage, and damage due to slippage at the time of high-speed running can be prevented.

Abstract: PURPOSE:To attain a high coding efficiency by obtaining a coded picture element and a context through the extraction of the picture element based on template from binary image data read in a line memory and setting an accurate augend depending on an incident probability of a symbol. CONSTITUTION:Binary image data by three lines are read in a line memory 501 and subject to picture element processing 502 based on a template to obtain a context CX and a coding noted picture element PIX. Number of times of appearance of the CX and the count of the picture elements PIX are stored in an SRAM 504 by count processing 503. A variable conversion processing 505 obtains a symbol appearance probability based on the values and the probability is converted into a product of primes by a prime conversion table 506 and its power is stored in the SRAM. A register arithmetic processing 508 multiplies the appearance probability in the SRAM with a range of the probability. An augend is expressed as a product of primes and sets of power are added when it is updated. A code when an incident probability deteriorated symbol is generated for a reference code and compared with coded data to discriminate whether the decoded symbol is a superior symbol or an inferior symbol and decode.

Abstract: PURPOSE:To carry out the speedy, highly accurate phenomenon simulation(SL) of the quenching of steel by performing the SL wherein the influence of stress upon temperature and phase transformation is ignored when a composite field of temperature, stress, and phase transformation is analyzed. CONSTITUTION:The 1st SL part of this device performs the SL of temperature distribution variation and transformation phase distribution variation according to a temperature distribution arithmetic expression for calculating the temperature distribution variation by varying the transformation phase distribution of the steel and a transformation phase arithmetic expression for calculating the transformation phase distribution variation by varying the temperature distribution. At this time, the influence of the stress is removed by considering that the influence of stress upon the transformation start temperature and transformation speed can be ignored. Further, the 2nd SL part performs the SL of the external deformation variation and internal stress variation of the steel according to the temperature distribution variation and transformation phase variation which are obtained by the 1st SL part. The SL by the 1st and 2nd SL parts is carried out speedily with high accuracy. Thus, the quenching conditions of the steel are reset to the best conditions according to the hardness distribution variation of the steel found from the transformation phase distribution variation obtained by the 1st SL part and the variation of the external deformation and internal deformation of the steel obtained by the 2nd SL part.

Abstract: PURPOSE: To provide the construction suited for high speed copying by providing two sheets of scanning mirrors which condense the luminous fluxes given from a plurality of stationary light sources to the same point on the original plane and the lenses which are movable in the same direction at the same speed as said scanning mirrors.  
     CONSTITUTION: Stationary light sources 3, 3' form the optical paths of a fixed angle to an original platen 1 and are so constituted as to condense light to the different points on the same plane as the original plane 2. A scanning mirror 4 is placed perpendicualary to the original face and reciprocates parallel from nearly the right end of the original platen 1 up to the alternate-long-and- two-short-dashes-line position and the scanning mirror 4' from nearly the center of the original platen up to the alternate-long-an-two-short-dashes-line position. Light from the stationary light sources 3, 3' radiates the original platen 2 by way of the scanning mirrors 4, 4' respectively and the reflected light thereof images the original image on the photoreceptor 6 by the lenses 5, 5'. The moving distance of the scanning mirror 4, 4' is about half the original face length. Hence, the moving speed of the scanning mirrors 4, 4' becomes about half the speed of the scanning light of the original plane 2. Hence, the moving mass of the scanning mirrors, etc. become smaller and the construction suited for high speed copying is made possible.

Abstract: PURPOSE:To compensate a vertical error of a part where a modulation chrominance signal is inversely proportional to the amount of light, by suppressing a high amplitude part of an output signal of a narrow band LPF, expanding the high amplitude section at a logarithmic circuit after clipping the signal below a prescribed level so as to attain vertical chrominance error compensation. CONSTITUTION:After the high amplitude section is suppressed for a part of an output signal of a narrow band LPF 206 through the logarithmic circuit 208, the signal is delayed by 1H period, an original signal and a signal subtracted at a subtractor 210 are obtained, this signal is expanded for the high amplitude section at an exponential circuit 21 for the vertical color error compensation. In this case, a part being a prescribed level or below of a narrow band luminance signal YL is clipped and eliminated at a clip circuit 61, subtracted with the original signal YL at a subtracter 62 by arranging the level and this signal is applied to a logarithmic circuit 208. Thus, a curve close to an input/output characteristic curve of a modulation color signal is formed and the correcting signal of vertical color error compensation is obtained, allowing to avoid the vertical color error from being distincted.
