Title: Method for inspecting defect of pseudo periodic pattern
Inventor: AKIYAMA YOSHIHISA
IPC: G06T7/00
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To reduce the detection of defects of pseudo periodic pattern without increasing the cost for inspection and without needing the labor and time to cope with every product class by comparing a result obtained in an emphasizing process with a prescribed slice level thereby extracting the candidate of a defective part. SOLUTION: The total value SUM of the pixel values of surrounding array elements 321, 322 is expressed by SUM (-ΔX, -ΔY) and SUM (+ΔX, +ΔY) as the function of a distance from each array element. The derivative value (Bibunti) of SUM data of the noticing element 322 becomes Bibunti=SUM(-ΔX, -ΔY)+SUM(+ΔX, +ΔY)-2×SUM. In order to compare the noticing element 322 with surrounding array elements, the arithmetic of a formula is to the whole of prescribed division. Since the derivative value (Bibunti) being an arithmetic value becomes remarkably different from the others only when the sum of the values of the pixels of the noticing element 322 is different from that of its surrounding, the candidate of the defective part can be detected by comparing it with a prescribed value (slice level).

Title: Manufacture of semiconductor device
Inventor: UEDA TAKASHI
IPC: H01L21/265
Filed: 1989-07-04
Abstract: PURPOSE:To prevent charge-up induced due to electric charge of implanted ions by using conductive organic polymer as a photoresist mask. CONSTITUTION:In an ion-implanting process using electron shower, polyacethylene 11 is used as a photoresist film. Since conductivity is high, negative charge is supplied electrostatically from a wafer clamper fixing a wafer 13 on a disk 12, even when the resist film is positively charged by phosphorus ion. Thereby the positive charge is electrostatically neutralized via the resist film, and charge-up controllabity in the case of fine pattern implantation is promoted.

Title: Ultrasonic motor
Inventor: TAKEDA KATSU
IPC: H02N2/00
Filed: 1988-07-12
Abstract: PURPOSE:To improve driving efficiency of an ultrasonic motor by employing secondary bending vibration in a radial direction and tertiary bending vibration in a circumferential direction as vibration modes, and mounting a plurality of concentric protrusions on a vibrator. CONSTITUTION:In an ultrasonic motor, a piezoelectric element 8 adheres to one main face of a disc-shaped elastic element 7 thereby to construct a vibrator 10. A mechanical output producing protrusion 9 is composed on the other main face of the element 7. Further, a frictional material 11 of a wear resistant material adheres to an elastic element 12 each other to construct a moving body 13 to be driven by pressure contact with the protrusion 9. Secondary bending vibration in a radial direction and tertiary bending vibrations in a circumferential direction are excited so that the vibration displacement state of the vibrator 10 is not abruptly reduced in displacement on the inner periphery. Accordingly, when ultrasonic motors occupy the same volume, kinetic energy of the vibrator 10 can be increased larger than that when the radial primary vibration mode is employed.

Title: Ring trip circuit
Inventor: UNZAI MINORU
IPC: H04M19/02
Filed: 1983-09-20
Abstract: PURPOSE:To prevent erroneous ring trip of a telephone set using a cold cathode discharge tube to a bell circuit by connecting a fault detection circuit to a ringing sender side and connecting a ringing detecting circuit 59 a ringing return side. CONSTITUTION:When an incoming call comes, ringer relay contacts 12a, 12b are switched to form a closed loop, a current from a ringer generator 9 flows to the cold cathode discharge tube 14 and a bell coil 15; a bell rings and the tube 14 irradiates. A half waverorm voltage of a ringer current is produced across a resistor 19, but since the voltage is lower than the detection voltag of a fault detection circuit 22, no logical signal is outputted from the circuit 22. When a telephone set 17 hooks off, a switch 16 is closed, no ringer current flows to the tube 14 and the coil 15, a voltage due to synthesized current of an AC currentfrom a generator 9 and a DC power supply 10 is generated across a resistor 18, a DC voltage is outputted to an LPF20, converted into a logical signal at a converter 21, a scanning signal appears at a terminal 23 and ring trip is applied. In case of line contact, a large current flows to a resistor 19 and a circuit 22 outputs a logical value.

Filed: 1984-08-20
Abstract: PURPOSE:To decrease a turbulence of a scanning line and to improve of picture quality by investigating inertia in a sub-scanning system peculiar to a type of a facsimile, driving a motor at the pulse interval where residual vibration becomes smallest and further delaying read timing. CONSTITUTION:When a four-pulse motor is impressed in the subscanning system, a reduction ratio and a feed roller of a timing belt are set so that one line is fed, and with four lines as one unit, a pulse interval of 16 pulses impressed to a motor is changed, and tghen, vibration response of the sub-scanning system is displayed as the feed roller displacement due to a motor driving at a longitudinal shaft. When the pulse interval is changed to t0, t1 and t2, residual vibration becomes smallest for the pulse interval t0. On the other hand, when the smallest compressed time of one line is T0, the vibration is properly arranged in four T0 time for the pulse interval t0. Consequently, when the motor is driven by an equal pulse row of the pulse interval t0, a picture quality becomes better.
