Title: Image forming device
Inventor: MITSUHAYASHI TAKESHI
IPC: G03G21/00
Filed: 1982-08-11
Abstract: PURPOSE:To realize high performance and high reliability without any increase in cost, by using a D/A converter which is used in a voice information synthesizing part for combined use of control other than voice information synthesis when it is not in operation. CONSTITUTION:When an exposure selection button in a console panel 68 is operated selectively, the control circuit 69 in a reference voltage generating circuit 65 receiving its signal inputs a digital signal corresponding to the exposure selection button to the D/A converter 57 through a changeover switch 58. The converter 57 is disconnected from the voice synthesizing part 32 and connected to the circuit 65; this converter performs D/A conversion on the basis of the input digital signal to output an analog signal to an amplifier 70. The amplifier 70 amplifies to match the signal with exposure control and outputs the amplified signal to a differential amplifier 66. In this constitution, the converter 57 used in the synthesizing part 32 is used for the setting control over the quantity of light of the exposure lamp, i.e. circuit 65 in common to perform digital control, so exposure control with high performance and high reliability is performed without using a dedicated D/A converter.

IPC: G11B15/467
Filed: 1977-11-24
Abstract: PURPOSE: To obtain a high-quality reproduced picture which does not cause the screen distortion even with the static reproduction and the normal speed reproduction, by securing a long-time recording in which the tape is fed under one- to- αH/0.5m compared with the normal recording time.  
     CONSTITUTION: Here A has tracing from 1 of (a) of track A obliquely up to B-track 525. When one head reaches obliquely from 1 up to 525, the other head resproduces obliquely the next track from 262.5 of track B. In such way, no fraction is caused to the horizontal synchronous signal to be produced, and accordingly no screen distortion is caused. Therefore, the tape speed at the signal recording time is set substantially to one-to-αH/0.5m of the normal recording time in the long-time mode of under one-to-αH/0.2m of the long-time mode recording time (αH: shift number of the horizontal synchronous signal in the tape pattern; m: integer), so no screen distortion is caused even thoutgh the static reproduction or the normal speed reproduction may be given.

Abstract: PROBLEM TO BE SOLVED: To obtain a high polarizing performance for incident light in a tilted direction on a substrate surface by forming a film of a compsn. containing a specified liquid crystalline polymer and a dichroic dye and fixing the tilted orientation of the liquid crystalline polymer formed in a liquid crystal state. SOLUTION: The liquid crystalline film to be used is produced from a compsn. containing a dischrioic dye and a liquid crystalline polymer which can form tilted orientation in a liquid crystal state, and the tilted orientation of the liquid crystalline polymer produced in a liquid crystal state is fixed. Fig. d shows the polarizing characteristics for incident light in the tilted direction along the absorption axial direction from the normal line direction with respect to the substrate surface. In this case, the obtd. compsn. has a large absorbance of the polarization spectrum in the major axial direction and gives the max. polarization degree for the light entering in the perpendicular direction to the major axial direction of the dichroic dye. Figure e shows the angle of visibility characteristics of the polarizing performance in the absorption axial direction.  The film has the max. polarization degree in a direction tilted at a specified angle from the absorption axial direction. Thus, the film has an asymmetric angle of visibility characteristics in the lateral axial direction.

Abstract: PURPOSE:To produce high quality images with minimal density nonuniformity by installing surface-like cathodes which radiate thermions from their surface toward an anode. CONSTITUTION:In a vacuum space located over a grid 5, surface-like filament cathodes 6 are installed which radiate thermionic rays from their surface. Each filament cathode 6 is formed by densely arranging several filaments prepared by applying an oxide to fine tungsten wires in a direction vertical to a base plate 1. And, a pair of the filament cathodes 6 are installed symmetrical about the central surface where a phosphor array 3 is located. Because of the above structure, thermionic rays are radiated from the entire surfaces of the cathodes 6. Consequently, it is possible to form high quality images with minimal density nonuniformity.

IPC: G01R19/04
Filed: 1987-06-04
Abstract: PURPOSE:To detect a peak value without being influenced by a DC offset of an input signal, by coupling a circuit for detecting the maximum value of the input signal, and a circuit for detecting the minimum value of the input signal. CONSTITUTION:A signal of an input terminal 1 is amplified by an amplifier 16, rectified by a capacitor 9 whose discharge time constant is larger than a charge time constant, and by applying a negative feedback to the amplifier 16, a voltage of the maximum value of an input signal is applied to an output terminal. Also, when the lowest potential of a signal which has been inputted to the input terminal 1 is lower than the potential of a positive phase input of an amplifier 17, it is amplified and a capacitor 10 is charged, and a normal rotation output of an amplifier 18 descends to a prescribed value. On the contrary, when the lowest potential of the input signal is higher than the potential of the positive phase input of the amplifier 17, the voltage for charging the capacitor 10 decreases, and the voltage of the forward turn output of the amplifier 18 ascends. In such a way, the normal rotation output of the amplifier 18 becomes a voltage which has followed up a variation of a level of the low potential side of the input signal.
