Title: Image reader
Inventor: SUZUKI JUNICHI
IPC: H04N1/04
Filed: 1990-02-22
Abstract: PURPOSE:To improve the adhesion of an original on a supporting member by arranging the supporting member to support the original inclining in an upper oblique direction for an original feed direction at an image reading position, and sticking an original surface to the supporting member by bending. CONSTITUTION:Platen glass 11 that is a member to support the original inclined in the upper oblique direction for the original feed direction is arranged between a feed roller 8f and an ejection roller 8k. The original 9 fed with a pressing roller 8e and the feed roller 8f is prevented from tramping with a guide member 14, and the tip of it is introduced to the platen glass 11. Thereby, the original 9 can be fed so as to be stuck to a platen glass 11 side by bending. Therefore, the adhesion of the original 9 on the platen glass 11 can be heightened than ever.

Abstract: PURPOSE:To make it possible to detect eccentricity of a boat at high efficiency by providing a disk on the boat and rotating the boat so that projection on the periphery of the disk is detected by means of light-emitting and photosensing sensors. CONSTITUTION:In order to introduce a boat 16 into a precessing furnace after any eccentricity in the boat is adjusted to a normal position, the boat 16 is rotated by driving a turn table 22. Thereby, light-emitting and photosensing sensors 26 provided on the extension of a tangent line to the boat 16 detect projection on the periphery of a disk 25 arranged on the top face of the boat 16, according to whether an emitted beam is let to pass or interrupted. For example, if the boat 16 is deflected by an amount delta as measured from the center axis 17a of a susceptor 21 or of a heat insulating cylinder 17, this deflection delta will cause the projection of the disk 25 to interrupt the emitted beam 27 when the boat 16 is rotated. In this manner, eccentricity of the boat can be detected at high efficiency.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device preventing a locus of an electronic beam form shifting even when luminance is adjusted by providing a means simultaneously adjusting an applied voltage to an electron emission element and the applied voltage to a target. SOLUTION: A pulse width modulation circuit 106 outputs a voltage signal with a fixed amplitude modulating a pulse width according to the image data to apply it to terminals Dyl-Dyn of a display panel 101. In this case, a luminance adjustment circuit 107 outputs an indication of an output value to a drive voltage applying means 108 which imparts an amplitude of a voltage pulse at the time and a scan circuit 102. Then, the luminance adjustment circuit 107 outputs the indication for varying Vf, Va while keeping a ratio between the amplitude Vf of the voltage pulse and an acceleration voltage Va imparted to a high voltage terminal on a face plate to a fixed level according to an indication signal inputted from an external adjustment terminal.  Thus, a shift of the electronic beam due to luminance adjustment is eliminated, and the problems such as a color smear, etc., in the image forming device are prevented.

Abstract: PURPOSE:To stabilize an operation by receiving a data line, first and second reference lines as a difference input and outputting either high level or low level corresponding to the logical state of a memory cell based on the electric potential of the reference line of which electric potential is different from that of the data line. CONSTITUTION:The circuit operates based on the electric potential of a reference line of which the electric potential is different from that of a data line DL among a first reference line REF1 of low level and a second reference line REF2 of high level and differential-amplifies with the electric potential of the second reference line REF2 of the high level as reference when the data line DL electric potential is the low level and with the difference between the second reference electric potential of the high level and the data line DL electric potential of low level as an input. Conversely, the circuit differential-amplifies with the electric potential of the first reference line REF1 of the low level as the reference when the data line DL electric potential is the high level and with the difference between the first reference electric potential of the low level and the data line DL electric potential of the high level as the input. Thus, the difference between the reference electric potential and the data line DL electric potential becomes the different of the high level and the low level whichever level of high and low the data line DL electric potential is and an operation margin is increased. Thus, a sense amplification is executed stably.

Abstract: PURPOSE:To prevent external diffusion and to obtain a device having gate oxide films, whose defect occurring rate is decreased, by forming the first gate oxide film and a poly Si gate electrode having high impurity concentration, thereafter covering them with a non-added Si thin film, performing oxidation completely, and providing the second gate oxide film. CONSTITUTION:A P-type Si substrate 1 is isolated by SiO2 film 2. An SiO2 thin film 4 and poly Si 5, in which high concentration P is added, are overlapped. Patternings 4a and 5a are performed, and the surface is covered with non-added poly Si 6. Oxidation is performed completely, and SiO2 7 is obtained. The surface is covered with poly Si 8, and patternings 8a and 7a are performed. An N<+> diffused layer 10 is formed in an opening part. In this constitution, the second gate oxide film 7a is formed by the thermal oxidation of the non- added Si. Therefore, external diffusion of impurities from the lower poly Si gate electrode 5a to the active region in the substrate is suppressed. The specified value of the impurity concentration is kept especially at a region, where a channel region is formed. Highly stable characteristics are obtained with respect to a threshold voltage and the like.

Abstract: PURPOSE:To accurately detect a synthesis power of two signals whose frequencies differ from each other by squaring respectively a maximum value and a minimum value of an output of an envelope detector separately and adding the squared maximum value and minimum value. CONSTITUTION:Upon the receipt of two signals Acosomega1t, Bcosomega2t (A>B) whose frequencies differ from each other, an output of an envelope detector 1 is an AC waveform whose maximum value is A+B and whose minimum value A-B nearly around a value A.

Moreover, the output of the detector 1 is inputted to a peak detector 3 and passes through a square amplifier 5, then its output is expressed as (A+B)<2>. Furthermore, when the outputs of the amplifiers 4, 5 are inputted to an adder 6, its output is expressed as 2(A<2>+B<2>), and then, the power of the two signals whose frequencies differ is accurately detected.

Abstract: PURPOSE:To prevent the contents of a recorded tape from being erroneously erased by providing a lug break detecting means, a recording inhibition/ permission setting means and a control means. CONSTITUTION:The lug break detecting means 1 detects that the recording inhibition lug of a cassette half mounted on a cassette tape recording work part is broken, and the recording inhibition/permission setting means 2 sets a state to inhibit or permit recording to the tape in the cassette half mounted to a cassette tape recording and reproducing part. Therefore, only when the lug break detecting means 1 does not detect the break of the recording inhibition lug in the cassette half and the recording inhibition/permission setting means 2 sets the state of permitting recording, the recording operation to the tape in the cassette half mounted to the cassette tape recording and reproducing part is available. Thus, the important record not to be erroneously erased is prevented from being lost.
