Title: Method and appratus for magnetic domain pattern width measurement in bubble wafer
Inventor: FUSHIMI SATOSHI
IPC: G01R33/12
Filed: 1980-05-26
Abstract: PURPOSE:To measure the magnetic domain pattern width of bubble wafer with high accuracy and high speed, by irradiating a test piece with coherent monochromatic polarized light and measuring the diameter of a circle in the Fourier transform image for pattern image obtained via a perpendicular polarized plate. CONSTITUTION:The monochromatic light from a laser light source 9 irradiates a bubble wafer 13 via collimaters 10a, 10b and a polarized plate 11. A transmitted light forms a Fourier transform image on a primary dimensional image sensor 16 via the perpendicular polarized plate 11 and a Fourier transform lens 14. The test piece 13 is rotated by 180 deg. with a motor 27 via a signal from a clock pulse generator 17 and a control signal generator 18. During this time, the output of the element 16 is added to the content of a memory 21 and stored via an adder 19 and a memory control circuit 20. A peak value is detected at a peak detection circuit 22 and a pattern width is calculated via a gate signal generating circuit 23, counter 24, and a reciprocal oprating circuit 25. Thus, the magnetic domain pattern can be measured with high accuracy and speed.

Title: Electrostatic recording method
Inventor: TARUMI NORIYOSHI
IPC: H04N1/29
Filed: 1980-05-26
Abstract: PURPOSE:To enhance recording velocity in an electrostatic recording method utilizing ion current modulation, by dividing an ion current modulation electrode into plural blocks, retaining image signals in each given unit corresponding to the blocks, and successively applying them as parallel signals to each block. CONSTITUTION:Image signals converted with CCD5 are applied to an ion current modulation electrode 9 through a processing circuit 7. An ion current emitted from an ion generator 11 is modulated with a modulator 9 and a latent image is formed on a rotary drum 12. This ion current modulation is slow in recording velocity. Therefore, the electrode 9 is divided into 9b1, 9b2-9bm, 9a2-9am. The image signals are converted into parallel signals via a shift register 20 and a latch circuit 21, and they are applied to the electrodes divided into blocks, thus permitting the recording velocity to be made high.

Title: Ink jet type recorder
Inventor: SUZUKI YUJI
IPC: B41J2/05
Filed: 1989-03-23
Abstract: PURPOSE:To increase a number of gradation and to prevent resolution from decreasing by performing recording of different densities by making an ink drop collide against almost a same position on a recording medium a plurality of times. CONSTITUTION:A plurality of holes 6 of a film 4 correspond to one heating element of a thermal head 9 and therefore, one dot is formed by an aggregation of a plurality of microdots. Therefore, its ink density becomes thinner by comparing with that of one dot to which one hole corresponds. Then, mesh of a matrix is dotted two times to thicken the density. By this method the film which expresses only 5 steps of gradation with, for instance, a matrix of 2X2 can increase the gradation further by 10 steps, can lessen a size of a pixel also and can improve resolution.
