Title: Hard copy device
Inventor: YAMAGUCHI KANEO
IPC: G06F3/153
Filed: 1989-03-24
Abstract: PURPOSE:To obtain more effective multicolor expression by correcting the operation of an error between an output value and the original many-valued data for a near-by picture element without directly outputting the output value by an area gradation method. CONSTITUTION:The hard copy device is provided with a many-valued image memory 1, a selector 2 for selecting data to be applied to a multiplexer 4, a latch 5 for storing multiplied results, a shifter 7 for shifting the result of an adder 6, and a binarizing circuit 8 for developing the output of the shifter 7 by means of area gradation. An error computing element 9 compares many-valued image data Dc with the result Dh of the shifter 7 and outputs their difference value De. An FIFO capable of storing the differences De corresponding to one line of a thermal head and a means for executing the weighting operation of an error between many-valued image data Dc and its near-by picture element and outputting the result to the circuit 8 are also connected. When the weighting operation including two peripheral picture elements is executed by defining the target image data as Dx, y, a value to be outputted to the circuit 8 as Tx, y and an error as Ex, y, the value Txy can be expressed by an unshown equation. Since the value inputted to the binarizing circuit 8 has correlation with the original image data in said constitution, effective multicolor expression can be attained.

Filed: 1990-03-26
Abstract: PURPOSE:To prevent the lowering of adhesive properties with a resist by forming a Schottky junction by forming a first layer composed of the silicide of a high melting point metal onto a semiconductor substrate, shaping a second layer consisting of the high melting-point metal onto the first layer, forming a third layer made up of the silicide, etc., of the high melting-point metal and forming a Schottky electrode. CONSTITUTION:Si<+> ions are implanted into a semi-insulating GaAs substrate 1 as donor impurities, and a conductive layer 2 is formed through annealing. A WSix film 3, a W film 4 and a WSix film 5 are superposed and applied successively onto the conductive layer 2. Since WSix has adhesive properties with a photo-resist better than W, the resist is hardly peeled when the photo-resist 6 is applied onto the WSix film 5 as an uppermost layer, thus improving yield. The photo-resist 6 is patterned, and the WSix film 5, the W film 4 and the WSix film 3 are machined through reactive ion etching, thus shaping a gate electrode. The photo resist 6 is removed, the ohmic electrodes of a source and a drain are formed and the electrodes and the conductive layer 2 are coated with an inter-layer insulating film 10, and a semiconductor device is completed through wiring 11.

Title: Plzt light bulb
Inventor: SHIBAKUCHI TAKASHI
IPC: G02F1/055
Filed: 1982-05-01
Abstract: PURPOSE:To reduce the power consumption of an illuminating power supply which occupies the greater part of the entire power consumption, by implanting a cation to the surface of a PLZT plate to form a photoconductive layer. CONSTITUTION:Each ion of hydrogen, helium, argon and argon-neon mixture is implanted with acceleration of about 500keV on both sides of a PLZT plate 1 which shows a light diffusion effect with impression an electric field of 100- 200mu thickness. Thus an implanted photoconductive layer 13 is formed, and a transparent electrode 4 of In2O3 is formed at both sides of the layer 13. Most of the voltage is applied to the layer 13 whose dark conductivity is dropped and at a part where the writing light is not irradiated yet with voltage impression of the electrode 4; and the voltage can be ignored for a ferroelectric layer. Under such conditions, the picture information is written with blue light. Therefore the voltage is reduced to a photoconductive layer at an irradiated part, and a large voltage is applied to the ferroelectric layer at the center of the PLZT plate. As a result, a polarization component is produced at a light irradiated part to scatter the transmitted light. A scattering state is preserved even though the impressed voltage is eliminated. Thus a memory effect is obtained.

Title: Automatic x-ray inspection device
Inventor: FUKUZAWA KUNIYUKI
IPC: G01B15/00
Filed: 1990-03-23
Abstract: PURPOSE:To cope with short-period variation in X-ray intensity due to source voltage and load variation and long-period variation due to the aging of an X-rays tube by performing feedback control over the intensity of X-rays and suppressing the variation in X-ray intensity. CONSTITUTION:The high frequency voltage outputted by a high frequency generating circuit 1 is converted by a multistage voltage doubling circuit 2 into a high DC voltage, which is applied to the X-ray tube 3 to generate X rays. The X rays irradiate a body 7 to be inspected which is carried in an X-ray irradiation part by a belt 5 for conveyance. Then an X-ray transmission image of the body 7 to be inspected is converted by an image pickup tube 6 into an electric video signal, which is processed by an image processing part 8 to decide whether the body 7 is normal or defective. A defective is removed by a rejecting mechanism 9. Further, if the output voltage varies owing to load variation or a ripple nd the X rays vary in intensity, the frequency of the output voltage of the circuit 1 is varied to control the X-ray intensity to a constant value. The brightness of the X-ray image can accurately be compared with set gradations without being affected by the variation in X-ray intensity.
