Title: Semiconductor device
Inventor: YOSHIMASU TOSHIHIKO
IPC: H01L25/07
Filed: 1991-06-17
Abstract: PURPOSE:To provide a semiconductor device wherein an IC chip is mounted on a board so as to prevent its high speed performance from being impaired. CONSTITUTION:An IC 30 and signal transmission paths 12 are interconnected with each other by means of bump electrodes 31 having a thickness of about several tens of micrometers. A resin 32 is exclusively applied around the edge of the IC 30 in order to reinforce the strength of the bump electrodes 31 and to increase the reliability of the mounting. The use of the bump electrodes 31 results in a very small impedance at the junctions. Hence, it is possible to prevent impedance mismatching from occurring at the signal transmission lines between the IC 30 and a board 11 due to the resistance of the junctions when a fast signal is inputted, and therefore the high speed performance of the IC 30 is ensured. Also, the characteristics of the IC 30 will suffer no adverse effects from the resin 32, because the application of the resin is only limited around the edge of the IC 30.

The reference material 2 maintains the partial pressure of the steam on the electrode 3 side approximately constant in this case. The gas to be measured is continuously supplied into the element 1. The concn. of the hydrogen or steam is contiuously and stably measured in this way.

Abstract: PROBLEM TO BE SOLVED: To improve a shift shock by providing with torque reduction means for reducing an output torque of a prime mover in accordance with a change rate of an input rotational frequency at termination of inertia phase to reduce an input torque to a transmission at the time of shift. SOLUTION: An electronic control device for engine not only controls a throttle actuator 5 but also outputs a signal to a fuel injection device 7 and an igniter 8. A function of a step 1 which determines to be whether or not in the inertia phase corresponds to inertia phase detecting means. A function of a step 2 which detects a change rate ΔNt of an input rotational frequency corresponds to an input rotational frequency change rate detecting means. A function of a step 3 which calculates a torque reduction amount ΔTe of engine 1 and a function of a step 4 which reduces an input torque by only the torque reduction amount ΔTe at termination of inertia phase correspond to torque reduction means. Accordingly, a shift shock can be surely prevented or reduced by reducing a suitable amount of the input torque at suitable time.

Abstract: PURPOSE:To measure sonic velocity with high accuracy, by detecting the peak of a reflected wave detected and calculating two adjacent carrier frequencies wherein said peak shows the min. value. CONSTITUTION:The burst width of the burst-like ultrasonic wave from an ultrasonic vibrator 3 incident to a specimen 1 is made variable and, in such a state that the burst width is set to a value smaller than tau(=2l/v) (l: the thickness of the specimen, V is the sonic velocity thereof), the time interval tauof a reflected wave is measured by a reflected wave time interval measuring circuit 14. Further, in such a state that the burst width is set to mtau (m is a number larger than 1), the peak of the reflected wave is detected in timing (m-1/2)tau after timing detecting the reflected wave at first by a peak detection circuit 10. Then, the peak at the central part receiving no effect of the transient characteristics of rising and falling among the reflected waves present within a time of (m-1)tau<t<mtau is always detected and two adjacent carrier frequencies fn, fn+1 when the peak of the reflected wave becomes the min value are calculated and sonic velocity V is measured according to formula by a sonic wave analyser 13.

Abstract: PURPOSE:To easily extract a data signal by improving the S/N when a transmission signal from an IC card is received. CONSTITUTION:A transmission coil 1-5 and a reception coil 1-6 of a reader are arranged vertically so that parts of them are crossed with each other. That is, the reception coil 1-6 is arranged in an electromagnetic field formed by the transmission coil 1-5 so that a magnetic flux PHIa directed from one to the other side and a magnetic flux PHIb directed from the other side to the one side are interlinked simultaneously at a position where a difference of number of magnetic flux between the magnetic flux PHIa (interlinked magnetic flux in an area A) and the magnetic flux PHIb (interlinked magnetic flux in an area B) is minimized. Thus, a current induced in the reception coil 1-6 by the transmission coil 1-5 is minimized (nearly zero) because the magnetic flux PHIa and the magnetic flux PHIb in the opposite directions to each other are cancelled together.

IPC: G06K9/62
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To automatically discriminate whether a character string included in an optically read original image is the character string in language using alphabets or the character string in Japanese. SOLUTION: Area separation is operated to a bit map picture, and a character area is separated (step S101). Then, the extraction of a line is operated to the separated character area (step S104). Next, the number of spaces having width more than a prescribed value is counted for each extracted line (step S106). Then, a rate R of the number of spaces counted in the step S106 to the width of the extracted line is calculated, and whether the line is a line in Japanese or a line in language using alphabets (English in this case) is discriminated based on the value of the R (steps S107 and S108). Then, the character recognizing processing of the line is operated by using either an OCR(optical character recognition) for Japanese or the OCR for English according to this discriminated result (steps S109 and S110).
