Filed: 1987-08-03
Abstract: PURPOSE:To receive both horizontal and vertical linear polarized waves simultaneously and to improve the cross polarized wave characteristics, by laminating a radiating element circuit, two types of feeder circuits and a ground circuit onto an earth conductor via the dielectric layers. CONSTITUTION:A radiating element circuit 1 contains plural radiating elements 5 having patch elements 7 arranged into a matrix form within a square and circular slot 6. The elements 7 are formed into square or round forms so that the vertical or horizontal polarized waves can be received. While two types of feeder circuits 2a and 2b are electromagnetically connected to the circuit 1 and supply electric power to the elements 5 via the feeder lines 10a and 10b orthogonal to each other. A ground circuit 4 is set between both circuits 2a and 2b and plural slots 9 having sizes approximately equal to the outer dimensions of elements 5 are formed to the circuit 4. In such a constitution, both vertical and horizontal linear polarized waves can be received simultaneously and at the same time the coupling states can be avoided between circuits 2a and 2b as well as between lines 10a and 10b. Thus the satisfactory cross polarized wave characteristics can be obtained.

Title: Exposure control method for electrophotographic device
Inventor: MARUO SEIJI
IPC: B41J2/525
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To realize such a printing action that a fringe is suppressed by making the reverse electric field of the periphery of an image part generating the fringe weak by using an exposure control means and suppressing the generation of fringe. SOLUTION: A latent image is exposed and formed on a photoreceptor drum by an exposure control means and developed by the toner of two colors by a try-level developing method by using two developing machines. The required try-level of the surface potential of the photoreceptor is obtained by switching two laser drivers 14 and 15 by a switch 16. By controlling the potential around the image stepwise by the exposure, the peripheral electric field of the image is made weak and the surface electric field of the photoreceptor is improved to such a level that a fringe phenomenon is not generated. Then, a dedicated laser driver 17 is added in order to control the exposure and data inputted from a host device is stored in an image memory 19. Besides, a fringe correction decision circuit 18 deciding a condition for actuating the driver 17 for correcting the fringe is arranged.

Title: Digital fm demodulator
Inventor: SASAKI MIKIO
IPC: H03K9/06
Filed: 1986-08-20
Abstract: PURPOSE:To improve the precision and S/N by measuring the half period or the period of an FM signal and obtaining the reciprocal of this measured period by a reciprocal arithmetic circuit consisting of an integrator, a multiplier, and an adder and adding a constant to the output of the integrator by an adder to obtain an FM demodulated output. CONSTITUTION:A period tp of the sampled and digitized FM signal is measured by a period measurer 1, and a frequency (fp) corresponding to the period tp is obtained from the reciprocal of tp, and a carrier frequency (fc) of the FM signal is subtracted from the frequency (fp) to obtain the demodulated output of the FM signal. In a reciprocal arithmetic circuit 5, the input of an integrator 3 is converged to zero on conditions Cphi>phi and 1>tp>phi. If the output of the integrator 3 is defined as (fp) and the constant input of the adder is defined as Cphi at this time, fp=Cphi/tp is true. If Cphi is set to one when tp is one period and Cphi is set to 0.5 when tp is a half period, the frequency (fp) corresponding to the period tp is obtained in both cases. Since the reciprocal of the period is obtained by arithmetic operation, the precision is improved and S/N is improved.

Title: Fluorescent and phosphorescent manicure enamel
Inventor: OSAKA TAKESHI
IPC: A61Q3/02
Filed: 1985-09-03
Abstract: PURPOSE:To provide a fluorescent and phosphorescent manicure enamel emitting bright light in light place as well as dark place, by mixing a fluorescent pigment and a phosphorescent pigment in clear manicure enamel. CONSTITUTION:The objective fluorescent and phosphorescent manicure enamel can be produced by mixing a clear manicure enamel with a fluorescent pigment 2 and a phosphorescent pigment 1 (e.g. luminous pigment, light-accumulating pigment, etc.) separately or attaching the former pigment to the surface of the latter pigment. The clear manicure enamel 3 is a nitrocellulose-based liquid such as cellulose nitrate lacquer, acrylic lacquer, etc. Since the enamel has high specific gravity, both pigments are mixed homogeneously with each other in a state that the phosphorescent pigment particle is encircled with the fluorescent pigment particles having smaller particle size. Accordingly, the product emits extremely bright color having a luminance brighter than any of Munsell color standard tablets in light place such as under the sunlight or a fluorescent lamp. In a dark place, the fluorescent pigment particles 2 encircling the phosphorescent pigment 1 emit bright fluorescent color excited by the light emitted from the phosphorescent pigment.

Title: Feed mechanism for pickup device
Inventor: ANDO NOBUHIKO
IPC: G11B21/02
Filed: 1992-06-30
Abstract: PURPOSE:To stop a pickup in a precise position without making fine adjustment. CONSTITUTION:A screw shaft 3 which operates to feed the pickup 1 is rotationally operated via a transmission gear 6 disposed on an oscillating arm 17 turned and energized in accordance with the revolving direction of the motor 8. The turning of this oscillating arm 17 is restricted by a restraining plate 12. The pickup 1 moves this restraining plate 12 to release the restriction of the turning of the oscillating arm 17 upon arrival at a prescribed position. The transmission of the driving power to the screw shaft 3 is shut off by the turning of the oscillating arm 17 and the pickup 1 is stopped.

IPC: G11B23/03
Filed: 1988-08-05
Abstract: PURPOSE:To cause the arrangement of a fixed part and sweeping part and to smooth the rotation of an optical disk by causing an interval between the mutually adjacent sweeping parts to be wider than the sum of the height of the respective sweeping parts. CONSTITUTION:For the cross section shape of a cleaning linear 6, a fixed part 7 and a sweeping part 8 are alternatively returned and the cross section is almost wave-shaped. Then, an interval (l) between the mutually adjacent sweeping parts 8 is formed to be wider than the sum of height (h) of the respective sweeping parts 8. The plane shape of the liner 6 is a rectangular shape to have width W, which is slightly larger than a recording area 11 of an optical disk 4, and length L, which is smaller than the recording area 11. Then, both right and left edge parts 13 and 12 are formed in a circular arc shape to have the same curvature as an inner-most circumference recording area 11a and an outer-most circumference recording area 11b respectively. As a result, even if the respective sweeping parts 8 fall down to an inside, the parts are not overlapped and the liner 6 goes to be high. Then, the smooth operation of an optical disk 7 is not interrupted.

Abstract: PURPOSE:To find the distance between a response apparatus in a transponder- type distance measuring system and a call apparatus at the side of the response apparatus CONSTITUTION:A signal generation mode control part 60 in a call apparatus 10 finds the generation period of a trigger signal by a trigger signal generator 16 on the basis of distance data, between itself and a response apparatus 40, which has been found by a distance-period conversion circuit 62 from a distance operation device 28. A comparator 68 outputs a trigger signal to the trigger signal generator 16 when the time counted by clock pulses of a clock 66 reaches a set value; it changes the transmission period of a call signal 30 which is output by an ultrasonic oscillator 24. On the other hand, a period detection circuit 70 in the response apparatus 40 finds the transmission period of the call signal 30 which is received by an ultrasonic oscillator 54, and sends it to a distance converter 74. The distance converter 74 reads out, from a distance data storage circuit 72, a distance corresponding to a period coinciding with the period found by the period detection circuit 70, and outputs it as the distance up to the call apparatus 10.
