Title: Pwm control circuit, microcomputer and electronic device
Inventor: KUDO MAKOTO
IPC: H03K3/017
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To obtain a PWM control circuit that can generate a PWM signal high in resolution with a small circuit scale and to obtain a microcomputer and an electronic device. SOLUTION: This PWM control circuit is provided with a PWM period setting register 10, a connector 12, an edge point setting register 14, a PWM output circuit 20 that changes a level of a PWM signal at a 1st edge point, and a delay setting register 16 that is provided additionally to a lower-order digit point of the edge point setting register 14 to specify a delay time off the 1st edge point. The PWM output circuit 20 delays the 1st edge point by a period shorter than one clock period of a CLK in response to a setting value of the delay setting register 16. Thus, the resolution of the PWM signal can be enhanced. A setting value in one or two bits is stored to the delay setting register 16, the 1st edge point is delayed by a half clock period in response to this setting value or the 1st edge point is delayed by 1/4, 2/4, or 3/4 clock period.

Filed: 1993-03-29
Abstract: PURPOSE:To shorten recognition processing time by trimming branches efficiently while securing a certain degree of a recognition rate in a search system in voice recognition or the like. CONSTITUTION:In an HMM-LR continuous voice recognizing system composed nearly of an HMM phoneme checking part 1 and an LR purger part 2, a neural network 6 is used as a control function. A recursion factor, a present depth of an LR analytic tree, a difference between the first place hypothetic score at present search time and the first place hypothetic score at right before search time are inputted to the neural network 6, and is learnt so as to output order of a hypothesis of a correct answer. Preferably, in order to prevent useless search by overevaluation, output of this neural network 6 and output by a variable beam search are compared with each other, and the one having a smaller value is selected.

Abstract: PURPOSE:To conduct a test at high accuracy by a simple device which makes its shift unnecessary by obtaining coordinates of at least one sheet end of an image picked up by lighting the joint of a sheet-like material at both sides of the joint. CONSTITUTION:The sheet 1 available from overlapping upper and lower sheets 1a and 1b is irradiated alternately by right and left light sources 3a and 3b of the joint.

The luminous energy shading is corrected 7a and smoothed 8a, and a noise is removed to store the image in a frame memory 9a. Then after a picture signal is integrated 10a, coordinates of a density distribution in a direction intersecting orthogonally with the joint is detected 11a and inputted to a deciding circuit 12. The image caused by the light source 3b is processed in the same manner, and a smoothed 8b signal is subtracted 13 from the output of the frame memory 9a and then processed in the same way as the system of the light source 3a and inputted to the deciding circuit 12. Then the shift of the device can be unnecessary and the test can be conducted at high accuracy.

Abstract: PURPOSE:To stably control the position and shape of plasma by varying the constituting elements of a coil current command value calculating circuit according to the deviations of plural pieces of parameters indicating the position and shape of the plasma from target values. CONSTITUTION:A control circuit consists of comparators 20, 21... which compare the magnitude of a plasma horizontal deviation epsilonrp, comparators 30, 30... which compare the magnitude of the plasma vertical deviation epsilonzp comparators 40, 41... which compare the magnitude of the deviation epsilondelta of the deformation quan tity of the plasma shape, amplifiers 50, 51..., 70 which are the constituting elements K11, K121, K122...K342, and adders 80, 81.... The comparators take the deviations of the respective controlled variables therein and output the deviations corresponding to positive and negative from the magnitude thereof. The coil current command value of a poloidal magnetic field coil attains relation expressed by the prescribed equation when the deviations are epsilonrp<0, epsilonzp>0, epsilondelta>0. This coil current command value is the optimum value for controlling the position and shape of the plasma as the magnitude of the numerical values of the constituting elements and the polarities of inclination vary according to the deviations of the respective controllers.

Abstract: PROBLEM TO BE SOLVED: To avoid a situation of generating faults in electrical and mechanical connections on a circuit board by controlling one or both of a conveying speed of the board and flowing velocity of molten solder, based on a measured result of the velocity of the solder. SOLUTION: At the time of releasing a circuit board dipped in a molten solder from liquid surface of the solder, a solder liquid level measurement signal from an encoder is received by a solder flowing velocity calculator 100 at a timing in synchronization with it, and the velocity of the solder is obtained.

Filed: 1978-06-14
Abstract: PURPOSE:To prevent the ignition time delay in high speed revolution by adding a simple switch circuit which allows the conduction rate of ignition coil to increase according to the revolution of an engine. CONSTITUTION:A power transistor 200 amplifies the output of an amplifying circuit I, and current detection resistors 161-163 generate voltage, responding to the primary current which flows in the power transistor 200. A current controlling circuit J restricts the maximum value of the primary current which flows in the power transistor 200.

A firing-position correcting circuit K is logically constituted of a proper voltage valve of the generation voltage in a pick-up coil B and the intermediate output in the amplification circuit I, and reduces the ignition time delay. A noise-killer circuit L allows the output of the bias level variation circuit E of the pick up coil B to be compulsorily uninfluenced by the effect of spark noise for a suitable time after intercepting primary current.

Filed: 1987-03-24
Abstract: PURPOSE:To detect a defect with a high accuracy without the use of a large magnet, by forming a magnetic field along the surface of material to be inspected with a first coil couple and a vertical magnetic field with a second coil couple to detect turbulence of a leakage magnetic flux and a vortex. CONSTITUTION:Circular coils 11, 12 and 13 are arranged concentrically at an equal interval. A detector 14 is arranged between the coils 11 and 12 composing a first coil couple while a detector 15 between the coils 12 and 13 composing a second coil couple. Connection method and winding direction of the coils are set properly to make the coils 11 and 12 the same in the direction of forming a magnetic field while the coils 12 and 13 are made opposite therein. With such an arrangement, a resultant magnetic field of the coils 11 and 12 is made along the surface of material A to be inspected while that of the coils 12 and 13 vertical thereto. When a crack-like defect B exists, leakage magnetic flux increases to be detected with a magnetic field detector 14. A pit-like defect C is detected with a magnetic field detector 15 by changes in eddy current. Thus, the use of an air-core coil enables simultaneous detection of two kinds of defects thereby miniaturizing the apparatus.
