Title: Ultrasonic motor, and electronic apparatus fitted therewith
Inventor: IINO AKIHIRO
IPC: H01L41/09
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic motor which transmits the drive force efficiently to a mover by reducing the elements through which the drive force generated in a piezoelectric element leaks to outside. SOLUTION: This is an ultrasonic motor 1 which is equipped with a piezoelectric element 10 for generating drive force, being oscillated by an inputted drive signal and support members 11 and 11 for supporting the piezoelectric element 10 onto a substrate 7. The support member 11 is equipped with a signal supply function which supplies the piezoelectric element 10 with a drive signal. Accordingly, there is no necessity to provide a signal transmission means separately, so the leakage of oscillation generated in the piezoelectric element 10 becomes smaller as compared with before. Therefore, the ultrasonic motor 1 transmits the drive force efficiently to the mover 12a.  Moreover, by making it have elasticity by providing the support member 11 with a constriction, the support member 11 doubles as a pressure contact mechanism which brings the piezoelectric element 10 into pressure contact with the mover 12a. In this case, the leakage of the oscillation generated in the piezoelectric element 10 becomes smaller more.

Title: Image processor
Inventor: MORI MIKIHIRO
IPC: B41J2/52
Filed: 1994-09-20
Abstract: PURPOSE:To apply the processor to a high speed system with comparatively simple configuration by providing a means for generating two specific patterns and a means for generating a binary signal to the processor, thereby eliminating broken or interrupted character or line and improving the resolution and reproducibility while keeping the gradation reproducibility of an intermediate tone image area. CONSTITUTION:Two triangle wave having a period twice the picture element period with high gradation reproducibility generated by pattern generating circuits 103, 104 are used for pattern signals to generate a binarizing signal with pulse width modulation. An edge direction detection circuit 107 detects the presence and direction of an edge based on the absolute value of a difference between two photoelectric conversion element with an attentional picture element inbetween and on the relation of quantity. If the signal is an edge, a proper triangle wave in the two triangle waves is selected depending on the direction, and the selected triangle wave and analog signal obtained by convering a digital picture signal are compared to select a generated binary signal with a time width. Thus, a picture having high quality is obtained.

Title: Magneto-optical recording medium
Inventor: TOKITA TOSHIAKI
IPC: G11B11/10
Filed: 1990-08-27
Abstract: PURPOSE:To prevent bits from being left to be erased and to reduce write error by inverting the magnetization of a recording part and a track part in an initial state in comparison with magnetization near those parts. CONSTITUTION:The magnetization of a recording part 3 in the initial state (unrecording state) is inverted to the magnetization of the track part and a part 4 close to it. In the magnetic domain structure of the magneto-optical recording medium, when anti-magnetic field energy is smaller than magnetic wall energy, the bit receives force to be shrunk generally and since the smaller the bit is made, the larger the anti-magnetic field energy becomes, however, it causes the erasing error in the case of erasing. In this example, however, since the direction of magnetizing the recording part 3 in the initial state and the direction of magnetizing the track part and the nearby part 4 are regulated as mentioned above, the anti-magnetic field from the track part and the nearby part 4 to the formed bit is suppressed small and the erasing error in the case of erasing is eliminated.

Title: Fault locator for closed type switch gear
Inventor: MURASE HIROSHI
IPC: H02B13/065
Filed: 1986-09-26
Abstract: PURPOSE:To achieve a higher reliability, by connecting a resistance between an electrostatic capacitance voltage divider and a surge detector section of a fault locator to make an input voltage waveform into a fault locator signal processing section approximate to an applied voltage waveform as much as possible. CONSTITUTION:Equipment with a higher insulation grade has larger values of capacitors 12 and 14 with a larger floating capacitance 11 thereof, which gives a larger value of L as combined value of the capacitances of the capacitors 12 and 14, hence requiring a larger resistance 20. Depending on the arrangement of equipment or the shape of a ground tank, a fault locator surge detector section 17 must be earthed at a position away from the electrostatic capacitance voltage divider. In this case, a due increase in the length of lead also requires a larger resistance 20 with a greater floating inductance. According to this invention, the arrangement of the resistance 20 between the capacitors 12 and 14 allows an input voltage waveform into a fault locator signal processing section to approximate to an applied voltage waveform thereby achieving a higher accuracy.

Filed: 1993-09-10
Abstract: PURPOSE:To highly accurately control the sleeping time of a CPU capable of executing intermittent operation. CONSTITUTION:In the case of starting the CPU 1 when a counter 4 counts an external clock signal 3 up to x periods in the sleeping state of the CPU 1, the periods of the signal 3 are highly accurately measured by means of a reference clock signal outputted from a reference oscillator 7 in accordance with a timing signal 6.

Title: Method and device for eddy current flaw detection
Inventor: MURAKAMI YOSHIHIRO
IPC: G01N27/90
Filed: 1993-07-28
Abstract: PURPOSE:To improve the detection sensitivity and S/N ratio for a very small defect by extracting a voltage difference induced in a secondary coil due to AC current supplied from an oscillator and then detecting the defect of a material whose flaw is to be detected according to the value. CONSTITUTION:Each adjacent head is driven in a reversed polarity manner to a magnetic field polarity produced by primary coils P of detection heads H1-H4, thus generating a magnetic flux distribution phi from the center pole of an E-type core C and making possible produced eddy current of a material 1 whose flaw is to be detected to indicate characteristics EC. When the produced magnetic fluxes cross in a beam-like manner in this configuration, the produced eddy current also becomes local. Therefore, when the head H is located at the mother material sound part of the material 1, magnetic fluxes produced from the center pole are divided and cross at a pair of secondary coils S1 and S2 which are laid out around the core C. Then, the material 1 moves in the X-direction and a defect I passes the coil S2, eddy current changes for the side of the coil S1 and magnetic flux density crossing the coil S2 changes due to reaction. By extracting voltage differences induced in the coils S1 and S2 and then measuring the values, the defect of the material 1 is detected.
