Title: Optical head
Inventor: KATAYAMA RYUICHI
IPC: G11B7/12
Filed: 1994-05-17
Abstract: PURPOSE:To obtain an optical head employing super-resolution having good reproduction characteristics of information signal recorded on a disc. CONSTITUTION:A polarizing phase shift plate 5a shifts the phase of an abnormal incident light to a circular region by an amount of pi and transmits a normal light substantially perfectly. A light emitted from a semiconductor laser 1 passes a collimator lens 2 and polarizing beam splitters 3, 4 and then impinges, as an abnormal light, on the phase shift plate 5a. Consequently, the light incident to the central circular region is subjected to phase shift by an amount of piand then passes through a quarter wavelength plate 6 to produce a circularly polarized light which is condensed through an objective lens 7 onto a disc 8. The light reflected on the disc 8 transmits the objective lens and the quarter wavelength plate 6 reversely and enters, as a normal light, into the phase shift plate 5a, the reflected light passes through the phase shift plate 5a substantially perfectly and reflected on the beam splitters 3, 4 toward a signal detection optical system.

Title: Electrostatic charging device
Inventor: KURITA TOMOKAZU
IPC: H01T19/00
Filed: 1988-04-27
Abstract: PURPOSE:To prevent image absence due to the partial scattering of a toner image by specifying the section curvature of a guard member at the abutting part where the guard member and a transfer material being conveyed abut on each other. CONSTITUTION:The insulating plate type guard member 64 on which the transfer material being conveyed abuts is provided to the opening part 40 of a conductive housing 34, and the section curvature of the guard member 64 at this abutting part is set to 0.1-0.2mm. When the section curvature is <=0.2mm, image absence due to the scattering of charged toner is not caused and when >=0.1mm, on the other hand, the contact part 64a of the guard member 62 for the transfer material is formed smoothly, so the transfer material does not be flawed. Consequently, the image absence due to the partial scattering of toner is prevented completely.

Title: Constant-voltage electric power source circuit
Inventor: NAKAMURA MASAAKI
IPC: G05F1/56
Filed: 1979-08-11
Abstract: PURPOSE: To make it possible to obtain the sufficient effect of suppressing instantaneous input variation by preventing a control transistor from getting saturated by interposing a diode between the control transistor and an error voltage amplifying transistor.  
     CONSTITUTION: Switching diode 12 is interposed between control transistor TR2 and error voltage amplifying transistor TR7. A potential at the anode of diode 12, i.e. point A is set lower than that at point B by resistance 13 within the stabilizing  range so that diode 12 will not turn on. As the input voltage falls and the collector  current of TR7 decreases, the potential at point A increases and when it exceeds its  setpoint, diode 12 conducts. Through this conduction, a blas voltage is applied to  the base of TR2 to prevent the saturation of TR2. Thus, the saturation of TR2 is  prevented, so that the sufficient effect of suppressing instantaneous input variation  can be obtained.

Abstract: PURPOSE:To maintain the humidity in a container mounted with an electrochemical cell at a low value over a long period of time even if power supply is stopped by providing a shutter mechanism in the communicating part between the inside and outside of the container so that the above-mentioned communicating part can be closed. CONSTITUTION:The electrochemical cell 8 constituted by forming porous electrodes 5, 6 on both surfaces of a proton conductive solid electrolyte film 4 is mounted to the part communicating the inside and outside of the container 1. Further, a circuit for impressing a DC voltage between the two electrodes 5, 6 is formed. The above-mentioned communicating part is made closable by the shutter mechanism 15. Consequently, even if the power supply is stopped, the inflow of the moisture into the container is prevented by properly operating the shutter mechanism 15. The low humidity is thus maintained in the container over a long period of time.

Abstract: PURPOSE:To attain a stable access operation by providing a control means which compares the output of a speed commanding means with that of a speed detecting means with each other and performs such control that the output of the speed detecting means is not used for speed control of a light spot when the difference between both outputs exceeds a prescribed value. CONSTITUTION:When the difference between outputs of a speed commanding means 9 and a period measuring type speed detecting means 6 exceeds the prescribed value, the output of the speed detecting means 6 is substituted with the output of the speed commanding means 9 or the just preceding output of the speed detecting means 6 and is not used for speed control of the light spot. When the difference between the present output and the just preceding output of the speed detecting means 6 exceeds a prescribed value, the output of the speed detecting means 6 is substituted with the just preceding output. Thus, the influence of the variance of a speed detection signal upon the speed control of the light spot is reduced even if a pulse due to a flaw or the like of a disk 1 is mixed in a track traverse pulse, and the stable access operation is available.

Abstract: PURPOSE:To attain an accurate data input process by storing the condition identification item number, the moving destination item number, etc., in a screen for the purpose of comparison with the input data and comparing this input data with a set parameter of a screen file to control the shift of a cursor after the end of the comparison. CONSTITUTION:An input control part 114 refers to a transaction screen file which is presently displayed to confirm the presence or absence of a dynamic control table. If no dynamic control table is available, a cursor is moved to the next item as prescribed. While the types are checked between the input data and the comparison data when the dynamic control table is available. If both types are coincident with each other, both data are compared with each other via an input data comparing part 113. Then the cursor is moved to the next item if no coincidence is obtained between both data. When the coincidence is obtained between both data, the part 114 recognizes the moving destination of the cursor. Then the shift of the cursor is displayed at a picture display control part 111. Thus an operator can input data with no consciousness of the necessary input items. Then the necessary input items can be satisfactorily comprehended.
