Patent JP-H02274562-A (JP)
Title: Printing head
Inventor: KITA KEIICHI
IPC: B41J2/28
Filed: 1989-04-17
Abstract: PURPOSE:To enable printing of good uniform density to be realized by making printing pressure of each printing wire constant by a method wherein printing pressure corresponding to a printing wire arranged vertically to a platen axle among printing hammer units is made larger as it goes toward up or downward directions from a center. CONSTITUTION:An amount of polishing of an armature 2 is made larger as it approaches a pin on an upside and a downside to a platen axle. By altering the amount of polishing of the armature 2 per each printing pin as abovementioned, each pin can be so arranged as to have such printing pressure as given in the figure. Further, as a preload is less, the printing pressure is higher. As the amount of polishing is more, the preload is less, therefore, the printing pressure becomes higher. By a preload altering means which alters the amount of polishing of the armature 2 per each printing pin based on this relation, the printing pressure is appropriately established. Thus, the printing pressure of each printing wire to a platen in actual printing is made constant, and printing of good uniform density can be realized.

Filed: 1988-04-18
Abstract: PURPOSE:To prevent the size of a semiconductor chip from increasing by providing an N-type diffusion area forming a base diffusion area and a pinch resistance between a base contact and an emitter diffusion area in the base diffusion area of a transistor. CONSTITUTION:An N<+> diffusion area 6 forming a pinch resistance within a base diffusion area 3 is provided between a base contact 8 and an emitter area 4. Thus, base current flows from the base contact 8 to a P<+> diffusion area 3 (base area) directly below the N<+> diffusion area 4 forming emitter area. Since the N<+> diffusion area 6 forms a pinch resistance, it is equivalent to connection of a resistor to the base in terms of circuit operation, thus prevent current hogging being generated even if a plurality of transistors are connected. It prevents chip area from increasing.

Filed: 1994-05-10
Abstract: PURPOSE:To precisely measure the shape of a non-spherical surface or a wave surface which is greatly deformed by two focusing lenses with difference focusing distance depending on the vibration direction of straight line polarization of incident light. CONSTITUTION:Light from a light source 401 enters a lens 403 to be measured after it converges by a collimate lens 402. A flux of light which is in nearly plane wave by the lens 403 enters a double focusing lens 404. The straight line polarization constituents vibrating in horizontal direction are scattered by the lens 404 as constant rays. The flux of light through the lens 404 enters a double focusing lens 405 as abnormal rays, the flux of light converges and is nearly converted to a plane wave. On the other hand, the straight line polarization constituents in vertical direction converge by the lens 404, are scattered by the lens 405, and are converted to nearly plane wave. The polarization directions of the two fluxes of light with different sizes are aligned to cause the fluxes of light to interfere each other and an interference image is formed on an image operation device 408 by an image forming lens 407. The image information is sent to an analyzer 409 and subjected to operation processing.

Title: Manufacture of gallium arsenide series solar battery
Inventor: SUGAWARA KAZUSHI
IPC: H01L31/0735
Filed: 1983-05-31
Abstract: PURPOSE:To improve the conversion efficiency by obtaining a large internal electric field by a method wherein, when a P type or N type GaAs layer is epitaxially grown in liquid phase with Ga fused liquid into the titled solar battery, the fused liquid is doped with two or more kind of P type or N type impurities of a large difference of diffusion coefficients, and a diffused layer of a large gradient of impurity concentration is generated by simultaneous diffusion. CONSTITUTION:An N type GaAs substrate shown by the layer III is doped with Al and As, and the fused liquid doped with Zn and Ge, the P type impurity, is put in contact with the substrate under the condition of high temperature, and thereafter the temperature is decreased. A P type GaAlAs shown by the layer  I is grown in such a manner, and at the same time the Zn and Ge in the fused liquid are diffused into the layer III, resulting in the generation of a P type GaAs layer shown by the layer IV. At this time, the Zn easily diffuses to the substrate, while the Ge does not easily diffuse because of a low diffusion rate. Accordingly, the large gradient of concentration caused by the Zn and Ge generates in the layer IV. Thus, the photoelectric conversion efficiency is enhanced by allowing the layer IV to have a large internal electric field.
