Title: Flexible disk device
Inventor: WADA MASAMI
IPC: G11B5/012
Filed: 1990-05-22
Abstract: PURPOSE:To obtain an enough margin to the two kins of recording density and to improve reliability and operability by providing two read/write gaps, which are made adjacent in the seek direction of a magnetic head, in one head slider. CONSTITUTION:In a conventional device, only first read/write gaps 10a and 10b are provided and in this device, however, second read/write gaps 9a and 9b are added. When using only the first read/write gap 10a or 10b, track width is made narrow in recording and when simultaneously using the first and second read/write gaps 10a, 10b, 9a and 9b, however, the track width is made wide in recording. This switching is executed according to the storing density of a medium to be used. Thus, the enough margin can be obtained to the two kinds of recording density, and the reliability and the operability can be im proved.

Title: Electrophotographic method
Inventor: TSUZUKI MITSUO
IPC: G03G15/04
Filed: 1978-10-26
Abstract: PURPOSE: To readily perform two color recording by forming two kinds of charge images of diferent polarities according to two kinds of image information.  
     CONSTITUTION: A developing means 107 for developing two kinds of electrostatic latent images of positive and negative with two kinds of toner particles of different polarities, and others are disposed on the outside circumference of a photosensitive drum 101 which comprises forming a photoreceptor 1 consisting of a conductive supporting substrate 2, photoconductive layer 3 and insulation layer 4 in durm form in such a manner that the insulation layer 4 positions on the outer side. Then, when the photosensitive drum 101 rotates, it undergoes primary charging with positive charges by a corona discharger 102, after which it undergoes secondary charging with negative charges by a corona discharger 103 while being scanned at such a pitch that light beams partly overlap with each other by a scanning light radiating means 104. At the same time, the light beams are intensity modulated by two kinds of recording information and further the positive and negative electrostatic latent images having been formed are developed to respective colors by the devoloping means 107 and are transferred to a recording medium 108 by a transfer means 109. Hence, two color recording may be obtained with the time and device equivalent to those for single color recording.

Title: Composite oscillator
Inventor: KUDOU AKIHITO
IPC: H03H3/04
Filed: 1977-11-02
Abstract: PURPOSE:To avoid giving the effect to one oscillator while the other oscillator undergoes the frequency adjustment, by sticking the material featuring a higher fusing point than the gold (Au) to the overlap area of the oscillator. CONSTITUTION:The Cr, the high-fusing-point material of W, Mo, Ta and the like, the Cr and the Au are sticked trhough the spattering 3a, 3b, 3c and 3d respectively of overlap area 3 between two units of tuning fork type crystal oscillator B1, and  B2 forming a composite oscillator. When laser beam l is trradiated at area 3 for  the frequency adjustment of oscillator B1, for instance, 3d and 3c can be fused away  by the light and heat. However, 3b could not removed away because it is a high- fusing-point material. Accordingly, light l does not pass through oscillator B1, so  the frequency adjustment is possible for B1 with no effect given to 3a and 3d on the  back and thus to the other side oscillator B2.

Abstract: PURPOSE:To provide a wide dynamic range by measuring time for the potential of a photodiode to reach a set potential by counting up clock signals. CONSTITUTION:A reset switch 2 is turned on, a reset signal (H) is turned to a signal R1 (L) by a NOT circuit, and an output C2 of an AND circuit 5 is turned to L. Thus, a photodiode 1 is grounded, a potential Vph of the photodiode 1 is turned to '0', the condition of Vph<Vref is established concerning a reference potential Vref, and a comparator 3 outputs a signal Out (H) to an AND circuit 4. The signal Out and a clock signal 'clock' are ANDed by the AND circuit 4 and outputted. The circuit 5 sends the clock signal to a clock counter 6 and the counter 6 counts up the clock signal. On the other hand, the potential of the photodiode 1 is increased corresponding to the intensity of incidental light, at the time of Vph>=Vref, the clock signal is cut off, and the counter 6 holds the clock counter value.

Abstract: PURPOSE:To facilitate the high speed scanning of laser light by scanning a modulated laser light at high speed in a direction in which the number of picture elements is small and at low speed in the direction in which the number of the picture elements is large. CONSTITUTION:By making a horizontal synchronizing signal H' for display be 60Hz and a vertical sync signal V' be 21.6kHz, the high speed scanning of 720 lines/sec in a vertical direction and the low speed scanning of 60 sheets/ sec can be performed in contrast with a usual TV receiver.
