Title: Rotary head cylinder device
Inventor: AMANO HIROKI
IPC: G11B15/61
Filed: 1990-06-08
Abstract: PURPOSE:To secure uniform contact pressure between a magnetic head and a magnetic tape extending over entire rotating phase by providing a groove part constituted at the outer peripheral cylindrical part of a rotary cylinder, and a groove shape varying means which varies the shape of the groove part corresponding to the rotating phase of the magnetic head. CONSTITUTION:The rotary cylinder 20 is formed in such structure that plural cylindrical members 24 and groove shape varying members 23 are laminated. The groove shape varying member 23 is made of a piezoelectric ceramic element, and is polarized and oriented so as to control the width in a rotating direction by applying a voltage by using the voltage supply means of a slip ring, etc., and the groove part 21 is composed in such a manner that the radius in the outer peripheral cylindrical plane of the groove shape varying means 23 is formed less than that of the outer peripheral cylindrical plane of the rotary cylinder 20. The shape of the groove part 21 can be varied corresponding to the rotating phase of the magnetic head 2. Thereby, since the thickness of an air layer 5 can be uniformalized extending over from the neighborhood of a scan start phase 16 to the neighborhood of a scan end phase 17, the contact pressure of the magnetic tape 4 on the magnetic head 2 can always be uniformalized.

IPC: G09G3/292
Filed: 1990-06-08
Abstract: PURPOSE:To set luminance or efficiency at an optimum value regardless of the number of scanning lines by impressing an (n) [the integer of ()>=2] number of scanning pulses to the (n) number of individual scanning electrodes respectively one by one during a maintaining pulse in one cycle of alternating current driving. CONSTITUTION:During the maintaining pulse in one cycle of alternating current driving, the (n) [the integer of (n) >=2] number of scanning pulses are impressed to the (n) number of individual scanning electrodes respectively one by one. For example, the pulse width of a maintaining pulse A, maintaining pulse B and scanning pulse is 5 microseconds, and the width of an erasing pulse is 0.7 microsecond. Synchronously with these scanning pulses, data are impressed and inserted to the electrodes of respective lines, and the erasing pulse is inserted at the same timing to scanning electrodes S1-S3. These erasing pulses are inserted in the range of Td=0-1 microsecond just after the maintaining pulse A, and wide allowable voltage width is obtained. Thus, the optimum luminance or efficiency is applied to the plasma display panel regardless of the frequency of the maintaining pulse or the number of scanning lines and can be set at the value so as to suppress the generation of heat.

IPC: G03C1/498
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To improve deterioration in photographic properties during storage of a heat developing material containing an org. silver salt, by controlling the half-value width of the X-ray diffraction spectrum of the org. silver salt to a specified value or smaller. SOLUTION: This heat developing material contains an org. silver salt and the org. silver salt is controlled to show <=21.0' half-value width in the X-ray diffraction spectrum. The org. silver salt contains a silver salt or org. acid having >=22 carbon atoms by >80mol%. The half-value width in a X-ray diffraction spectrum of an org. silver salt means the half width of the peak corresponding to the long-period structure when the X-ray diffraction spectrum is measured with 50KV an 180mA CuKα ray source. By using the org. acid silver having the half width above described, increase of fog due to storage can be prevented and good photographic properties are obtd. after storage. When the half-value width exceeds 21.0', increase of fog due to storage increases. By this method, deterioration in the photographic properties during storage can be improved.

Filed: 1994-07-04
Abstract: PURPOSE:To improve the detecting accuracy of a recording medium by transporting the recording medium between a detecting head and a roller, abutting it on the detecting surface of the detecting head by a roller and transporting it while sliding. CONSTITUTION:Since the outer peripheral surface 31c of a roller 31 is rotated while abutting on the rear surface 16 of a bill 2 by sliding the bill 2, a roller 31 is always kept in a transparent state by self cleaning action. Consequently, the scattering and the attenuation of light on the outer peripheral surface 31c of the roller 31 are sharply reduced, the most part of the light beam transmitted through the bill 2 is made incident on the roller 31, reflected by the reflection surface 31a and received by a photodetector 32. In this case, the transmitted light beam through the bill 2 is hardly affected by the influence even when some gaps exist between the bill 2 and a detecting head 11 and the roller 31 and the variation of the output of the photodetector 32 is small.

Title: Speed controlling system of tone arm
Inventor: YASUDA HIROSHI
IPC: G11B3/36
Filed: 1981-09-28
Abstract: PURPOSE:To control the shift of a tone arm, by generating the pulses of different duty cycles in response to the operation of a switch and then smoothing the generated pulse to supply a current to control a tone arm driving motor. CONSTITUTION:A CPU14 containing a microprocessor gives an operation to the contents of a counter and an output memory with operations of low-speed and high-speed forward switches S1-1 and S1-2 plus low-speed and high-speed reverse switches S2-1 and S2-2. Thus the forward pulse is fed to terminals 15 and 16, and the reverse pulse is fed to terminals 17 and 18 respectively. With the output of the forward pulse to the terminals 15 and 16, a TRQ4 is turned on. Then the speed command signal smoothed by a resistance R1 and a capacitor C1 is supplied to the base of a TRQ1. The voltage corresponding to the base voltage is delivered from an emitter, and a motor 19 is controlled. The same operation is carried out also with the reverse pulse. Thus a tone arm can be accurately transferred with operations of the terminals S1-1-S2-2.

Filed: 1991-06-25
Abstract: PURPOSE:To improve resolution of the whole picture area, by newly inserting an auxiliary electrode to be A.C.-grounded, between a focusing electrode composing color picture tube and an intermediate electrode adjoining thereto. CONSTITUTION:An auxiliary electrode Gs is newly placed between the 5th grid G5 and an intermediate electrode Gm1 composing an electron gun. Thus capacitance C5s, Cmm, and Cm6 are generated between respective electrodes: the grid G5, auxiliary electrode Gs, intermediate electrodes Gm1 and Gm2, and 6th grid G6. Especially, it means that the capacitance C5s is grounded through a capacitance CCRT of a picture tube itself formed by an inner conductive film and an outer conductive film of the picture tube. On the other hand, the capacitance Csm between the electrode Gs and Gm1, and the capacitance are turned into a short circuit state with a lead wire connecting the electrode Gs and the grid G6. An A.C. voltage component 10a shaped in palabola applied to the grid G5 is thus not inducted to electrodes Gm1 and Gm2, and only appropriate D.C. voltage is applied to the electrodes Gm1 and Gm2.
