Title: Re-sample clock regenerating circuit
Inventor: KOIZUMI TOSHIO
IPC: H04N9/80
Filed: 1993-01-28
Abstract: PURPOSE:To apply the circuit to a system having a large frequency change by obtaining a value being a multiple of a coefficient with a sampled quantization phase error signal subjected to resampling at a frequency over a specific multiple of a sampling frequency and a quantized oscillation phase angle calculated from a median of oscillated frequencies of a VCO. CONSTITUTION:A coefficient (k) is multiplied by a quantization error signal x(nT) from a phase comparator sampled by a frequency of 97.2MHz in a loop filter 1 and a quantization phase angle phi(nT) is calculated according to equation 1 in figure (b). In this case, a median of oscillated frequencies of a VCO is set to omega0, calculated by 24-bit fixed decimal point and a sine transformation circuit 2 outputs sine functions y(nT) equal to each other based on the phi(nT). A D/A converter 3 and a filter 4 convert the output into an analog quantity and a pulse converter 5 converts the analog quantity into a rectangular wave and the oscillated frequency 16.2MHz of the VOC is controlled by a sampling frequency being thrice to 6 times. Thus, the circuit is applied to a system having a large frequency change.

Abstract: PURPOSE:To heighten the yield, and to manufacture the cold rolled steel sheet conformable to the standard, by irradiating the radioactive beam, whose cross section is flat and long in the direction of longitude of the steel sheet, for the purpose of directly measuring the thickness at the region near but out of the side edge of the steel sheet. CONSTITUTION:At rolling the steel sheet 1 by the cold rolling mills 3-7, the thickness measuring devices 11, 12 for measuring the thickness (t) nearby the side edge 2 of the steel sheet 1 are employed additionally to the conventional thickness measuring devices 8-10 for measuring the thickness T at the middle of breadth of the steel sheet 1. These additional thickness measuring device 11, 12 are installed behind the final rolling stand 7, and each of them directly measures the thickness (t) at a spot very small distance (a) far from both of side edges 2, 2 of the steel sheet 1. As a result, the steel sheet 1, conformable to the standard applied to the steel sheet to be sold for the price based on the calculated weight, is manufactured in high yields. In the above case, the radioactive beam 15, whose cross section is flat and long in the direction of longitude of the steel sheet 1, is irradiated upon the spot nearby the side edge 2 of the steel sheet 1, and the thickness (t) therein is directly measured by using the devices 11, 12.

Abstract: PURPOSE:To obtain bar code-reading of a big commodity with a simple means by tilting a center line in a bar code reading area by means of a bar code reading window arranged on the lower forward of a main body ahead of a plumb line. CONSTITUTION:Since a center line 7 of a bar code reading area tilts ahead of a plumb line 8, a bar code 47 attached to a too big commodity 46 to enter an interval 10 can be read if the big commodity 46 is tilted and only a bar code pattern is set to a bar code reader. The bar code pattern 47 changes an optical path through a window 48 by means of three reflecting mirrors 40, 41 and 42, and image-formed on the one-dimensional image pickup element by an optical system 43. The one-dimensional image pickup element is supported on a print substrate, and amplifier, shaping and binary-coding circuits of an output electrical signal of the one-dimensional image pickup element are accommodated in the print substrate. A binary signal is decoded in a bar code decoding part (not shown in the figure) accommodated at the bottom of a stand 51.

Title: Method and apparatus for painting conductive paint
Inventor: YAMAMOTO YOSHIKAZU
IPC: B05C9/08
Filed: 1984-02-23
Abstract: PURPOSE:To enhance shield effect by preventing Ni-particles from coming up to the surface of an object to be painted, by applying a magnetic field when a paint containing Ni-particles is subjected to spray painting. CONSTITUTION:When the spray painting 12 of a conductive paint containing nickel particles is performed, a magnetic field is applied to a steel plate 4 by an electromagnet formed by winding a coil 5. Whereupon, painting is performed so as to gather Ni-particles to the inside prior to forming a film and, therefore, the steel plate 4 becomes hard to oxidize and shield effect after heating deterioration is improved.

IPC: H01J49/10
Filed: 1984-02-23
Abstract: PURPOSE:To prevent the loss of generated ions by providing a throttle hole in an ionization box and a nozzle opposed to this throttle hole, spraying reaction gas from the nozzle, injecting the gas in the ionization box through this throttle hole, and ionizing the reaction gas between the nozzle and the throttle hole. CONSTITUTION:A throttle hole 8 provided in an ionization box 1 is a pore at a diameter of 0.2-0.4mm. and a nozzle 9 is arranged separated from this throttle hole by approximately 0.4-1mm.. The nozzle 9 has the hole diameter of approximately 0.1-0.2mm. and a filament 4 and an anode 10 are arranged opposedly between this nozzle 9 and the throttle hole 8. Both the filament and anode form an electron flow accelerated by crossing the jet stream of the reaction gas formed by the nozzle 9 and ionize the reaction gas. A greater part of the reaction gas sprayed from the nozzle 9 is dispersed and a part of it is advanced in the ionization box, but the reaction gas will not flow from the ionization box through the throttle hole 8. As a result, since there are few losses of the generated ions and there are no electron incidence holes, the efficiency of an ion source is improved and sensitivity is increased.

IPC: G01R7/02
Filed: 1985-02-22
Abstract: PURPOSE:To make it possible to prevent the rising in temp. even if the battery capacity of a car increases, by connecting the voltage terminal of the current dividers inserted between a plurality of alternators and a battery to a plurality of windings of an ammeter. CONSTITUTION:The direction of the DC current traversing a current divider Sh2 is determined by the difference between the output of an alternator G2 and the magnitude of the sum of the inputs of loads L21-L23 connected to said alternator G2 and the discharge current or charge current of a battery B2 is flowed to the current divider Sh2. A discharge current or charge current is also flowed to a current divider Sh3 in the same way by the difference be tween the output of an alternator G3 and the sum of the inputs of loads L31-L33. These two divided currents flow to the coils C1, C2 of an ammeter A2 and the discharge or charge current quantity of the battery B2 is displayed by an indicator N. By this mechanism, a current divider for a large current becomes unnecessary and, therefore, the rising in temp. can be prevented.
