Title: Error processing system
Inventor: OKAZAKI SUSUMU
IPC: G11C29/42
Filed: 1980-12-26
Abstract: PURPOSE:To enable the correction of a plurality of errors in the same word and to increase the reliability of memory, by corresponding the address at error generation in a memory block to another word location. CONSTITUTION:If a data read out from memories M1, M2 has one bit error, a plurality of errors are generated in the same word and an error detection signal is generated. This signal is corresponded to either one of timing circuits 3, 4 as an inversion signal. For example, at the circuit 3, the inversion signal via an NOT circuit 6 outputs a negative logic of a basic timing signal as a timing signal to an address multiplexer 1. Thus, the circuit 1 gives a row address in the timing to be applied to a column address M1 in the row address in the input address and applies the column address in the timing to apply the row address. Thus, correction can be made with one bit error correction and two-bit error detection mechanism.

Title: Optical writing device
Inventor: MASUBUCHI SADAO
IPC: G03B27/73
Filed: 1990-07-17
Abstract: PURPOSE:To enable a chromatically balanced color image to be outputted by changing the number of color pixel arrays for each color in accordance with the intensity of a light for writing process from a color pixel array for each color on a photosensitive member and the photosensitivity of the member to each color so that the photowriting intensity of colors on the photosensitive member becomes uniform. CONSTITUTION:First data are written to a single point on a photosensitive sheet which moves in an arrow direction 5, once at a red pixel 1, twice at green pixels 2-1, 2-2 and then three times at blue pixels 3-1, 3-2, 3-3 using a blue light. Consequently, it turns out that a single spot on the photosensitive sheet receives data written using the red light once, the green light twice and the blue light three times. The wavelength characteristics of light intensity of a halogen lamp are such that the green and red lights are more intensive than the blue light. Therefore, the wavelength distribution of light intensity of the halogen lamp is corrected by increasing the number of blue and green pixel arrays compared to the number of red pixel arrays. Thus the intensity of blue, green and red lights, to which the photosensitive sheet is exposed becomes almost uniform and a chromatically balanced image can be obtained.

Abstract: PURPOSE:To achieve improvement of durability by preventing buckling and failure which are generated at an elastic deformation part of a plate spring on a needle side by a method wherein elastic strength of the elastic deformation part of the plate spring on the needle side is raised higher than elastic strength of the elastic deformation part of the plate spring on the main frame side. CONSTITUTION:A needle 5 is arranged at the opposite end in an expansion and contraction direction of a piezoelectric element 1 which is expanded and contracted by application of voltage under a state in which it is opposed to an upper end part of a riser part of a main frame 2. Further, a pair of plate springs 6, 7 are fixed at one end part thereof onto opposed faces of the needle 5 to the main frame 2 by brazing. Furthermore, a plate thickness t2 of the elastic deformation part 7b of the plate spring 7 fixed to the needle side is so established as to be thicker than a plate thickness t1 of the elastic deformation part 6b of the plate spring 6 fixed to the main frame 2 side. Elastic strength of the elastic deformation part 7b of the plate spring 7 on the needle 5 side is raised to be higher than elastic strength of the elastic deformation part 6b of the plate spring 6 on the main frame 2 side. Fatigue degree of the elastic deformation part 7b of the plate spring on the needle side is controlled less by the raised content of elastic strength. Therefore, buckling and failure of the elastic deformation part can be actively prevented and its durability can be improved.

IPC: H01L29/812
Filed: 1987-07-29
Abstract: PURPOSE:To satisfy both a low parasitic resistor with a bilateral asymmetric bored opening section and high drain breakdown strength by forming a gate electrode into an opening region obtained by removing a high-concentration N-type GaAs layer through an isotropic dry etching method from the oblique direction to the surface. CONSTITUTION:A gate electrode metal is applied into an opening region acquired by removing a high-concentration N-type GaAs layer 6 through an isotropic dry etching method from the oblique direction to the surface, and a gate electrode 11 is shaped through a lift-off method. Consequently, since the layer 6 is dry-etched in an isotropic manner from the oblique direction, side etching to a mask pattern asymmetrically progresses, thus displacing the center point of the lower section of a recess to the center point of the mask pattern. Evaporating beams are projected vertically to the mask pattern and the gate electrode is formed, thus shortening the distance of a bored opening section between a source and a gate, then lengthening the distance of the bored opening section between the gate and a drain.
