Abstract: PURPOSE:To dispense with the issue of the service tickets and to reduce the consumption of forms and the processing time in regard of a point card processor by calculating the point number equivalent to a transaction amount and performing the payment based on the point stored in a point card. CONSTITUTION:When a point payment key is pushed, a CPU 11 reads the point number out of point card and decides whether the point number reached a benefit level or not. If not, the CPU 11 displays a fact that the point number of the card is insufficient and finishes the processing. If so, the CPU 11 waits for the input of a transaction amount. Then the CPU 11 calculates the point number equivalent to the relevant amount after the input of the transaction amount and subtracts this point number from the read point number to acquire the remaining point number. When the remaining point number is larger than O, this number is written in the point card as it is. Meanwhile the insufficiency of the point number is displayed and the processing is finished when the remaining point number is smaller than O.

Abstract: PURPOSE:To contrive to cut don the cost and to uphold the productivity when numerous linear opening grooves are formed on the surface of a matter to be processed by a method wherein one or plural linear pulsed laser beam/beams is/are made to emit and the surface of the matter to be processed is irradiated with the pulsed laser beam/beams. CONSTITUTION:A pulsed laser beam having a wavelength of 400nm or less is irradiated on the surface of a matter 11 to be processed and a processing is performed on the surface simultaneously and instantaneously with one pulsed laser beam in the configurations of slits, each having a width of 10-20mum and a length of 10-50cm. Moreover, a beam from an excimer laser 1, which has the almost uniform intensity of light within the extent of the irradiation surface, is used for the initial beam to be irradiated. Therefore, the irradiation surface is formed into a large rectangular area or a long rectangular area by an expander 2 and the laser beam is condensed to the irradiation surface by the sylindrical lenses in the configuration/configurations of one or plural slits along the X or Y direction on one side of the X and Y directions of the irradiation surface. As a result, one or plural slit-shaped laser beam/beams is/are simultaneously irradiated and opening grooves 5 can be formed in the surface of the matter 11 to be processed. Accordingly, any damage is not inflicted on a base substrate 10 and the slit-shaped grooves 5 can be selectively formed in the non-single crystal semiconductor only. Powdered residues being left at the pats to be processed after the opening grooves are formed can be sufficiently removed by ultrasonic cleaning using a cleaning fluid. In this case, the surface to be processed is the surface of the non-single crystal semiconductor on the substrate.

Title: Waveform observing device
Inventor: ECHIZEN TETSUO
IPC: G01R13/20
Filed: 1984-10-29
Abstract: PURPOSE:To prevent a wrong waveform display due to the input of an over input signal by making the number of steps of the output signal of an AD converter larger than the number of longitudinal-axis picture elements, and displaying part of the output signal of the AD converter. CONSTITUTION:An input signal 6 is inputted from an input terminal 1 and converted by the AD converter 2 into, for example, a 7-bit digital signal, which is written in a memory circuit 3. Then, a read circuit 4 reads and decodes the signal and sends the decoded signal to a liquid-crystal display element 5. The display element 5 displays a waveform on a display screen 10 which have 64 picture elements longitudinally on the basis of the decoded signal. Then if the over input signal within a display range arrives, the converter 2 enters an overflow state and the waveform part is displayed as a straight line, so a correction display is not obtained. For the purpose, the number of steps of an output signal 7 is set to, for example, 128 which is larger than 64, i.e. the number of picture elements of the display element 5, and the circuit 4 displays 32-95 of the output signal 7 and on the 64 longitudinal-axis picture elements and does not display other values. Therefore, even if the over input signal is inputted, the straight line which does not correspond to the input signal is not displayed.

Abstract: PURPOSE:To keep the continuity of video signals at joints between scenes in a short period by applying speed control of a capstan motor and applying phase comparison of color fields. CONSTITUTION:When the phase of a color field recognition signal 23 and that of a reproduced color field recognition signal 30 are not coincident, a field comparison servo circuit 31 raises once a voltage of a speed control signal 33 and decreases the voltage of a speed control signal 33 gradually in a direction that the speed of the capstan motor 32 slows down as the deviation of the phase of the color field recognition signal 23 and the reproduced color field recognition signal 30 is decreased. Simultaneously, the phase of the color field recognition signal 23 and that of the reproduced color field recognition signal 30 are compared and when the phase is coincident, the capstan motor 32 is driven at a constant speed. Thus, the color field of the input composite video signal and that of the video signal reproduced from a magnetic tape are made coincident by one phase matching.

Abstract: PURPOSE:To change an ion implantation depth with one ion implantation apparatus not only with accelerating energy from said apparatus but also freely, by differentiating ion implantation angles into a wafer at one or more ion implantation steps from implantation angles in other ion implanting steps. CONSTITUTION:When a semiconductor device is manufactured in a semiconductor wafer through tow or more ion implantation steps, ion implanting angles into the semiconductor wafer in one or more ion-implantation steps are made different from ion implantation angles into a semiconductor wafer in other ion implantation steps. For example, when the channel region of an NMOS transistor is formed, a silicon oxide film 12 is formed on a P-type semiconductor silicon substrate 11 so that the film is thin on the channel and thick on the other region. Boron ions are inputted in a direction 13, which is inclined by seven degrees from the vertical direction toward the surface through the film 12. Thus a shallow boron doped channel layer 14 is formed. Then, the boron ions are inputted in the vertical direction 15 toward the silicon surface and a deep boron doped channel layer 16 is formed.
