Inventor: HARADA FUMIYA
IPC: C11B7/00
Filed: 1990-01-31
Abstract: PURPOSE:To separate oils and fats containing at least two species of phospholipid to specific phospholipid in high purity and a low cost without residue of a harmful component by using a mixed solution of ethanol and water as a mobile phase solvent of liquid chromatography. CONSTITUTION:For instance, ethanol is mixed with water in a weight ratio of 99/1-50/50 to obtain a mobile phase solvent. Oils and fats containing at least two species of phospholipid, preferably a mixture of phospholipid containing 20wt.% phospholipid is dissolved in said mobile phase solvent and separation is performed in liquid chromatography (e.g. a sort of column chromatography) previously dissolved with said mobile phase solvent. Used mobile phase solvent is solely distilled and concentration is re-adjusted to be used in many times. Besides, residual solvent in a separated product is safe and able to be used as a raw material for a drug or food.

Title: Information processor
Inventor: ISHIHATA NAOMASA
IPC: G06F9/48
Filed: 1989-01-30
Abstract: PURPOSE:To generate an optional vector address, to read out a required start address and to increase the number of routines by changing the level of upper bits in the vector address. CONSTITUTION:An upper address setting part X' selectively connects each bit line out of upper 12 bits in the vector address to a test signal line Q or a ground line G so that a required address can be previously obtained. Since the upper 12 bit are always held at the 'L' level when the line Q is in the 'L' level, a normal mode to be usually used by a user is set up. When the line Q is turned to an 'H' level, a test mode is set up and the upper 12 bits can be constituted of required bits by connecting respective bit lines to the line Q or G by the setting part X'. Thereby, a required starte address can be read out from a ROM 1 and the number of routines can be increased.

Title: Semiconductor laser device
Inventor: WADA MASARU
IPC: H01S5/223
Filed: 1980-02-19
Abstract: PURPOSE:To permit a high efficient and low-current operation of a semiconductor laser by a method wherein on an active layer a clad layer with the opposite conductive type and having a wide forbidden band width is formed so that current concentratively flows through said portion as well as is trapped therein. CONSTITUTION:A step is formed on an N type substrate 1. Then, an N type clad layer 2 is formed thereon. After an active layer 3 has been formed, a P type clad layer 4 having a convex bulge at the step portion is formed, and an N type clad layer 5 and an N type gap layer 6 are formed thereon. Then, from the layer 6, Zn diffusion 7 is performed until said P type front reaches the layer 4 to form a P type path in the layer 5. When a positive voltage is applied between the positive and negative electrodes 8 and 9 of a thus produced laser device, a reverse bias is applied between the layers 4 and 5 except for the diffused portion 7, so that current concentratively flows only through the diffused portion 7. In addition, the current injected into the layer 4 is restricted from spreading laterally and efficiently injected into the layer 3 at the step portion. Then, the light emitted from the layer 3 is trapped between both the clad layers.

Abstract: PURPOSE:To improve the paper feeding accuracy and the paper feeding speed, by providing a plurality of accelerating/decelerating data different to each other set corresponding to a plurality of paper feeding amounts, based on which data a paper feeding motor is driven. CONSTITUTION:When a paper feeding command is transmitted from a host device through an interface 24, an MPU 21 recognizes the paper feeding pitch designated by the paper feeding command thereby to select one from table areas 23b-23d corresponding to the paper feeding pitch from an ROM 25. The accelerating/decelerating data stored in the selected table area is transmit ted by the MPU 21 to a motor driving circuit 25 which in turn drives a paper feeding motor 26 by motor exciting signals of a cycle determined by the data. Thus, when the papers of a relatively small amount should be fed, the paper feeding speed is made lower, so that the vibrations of a rotor caused when the paper feeding motor is stopped are attenuated. Accordingly, the paper feed ing accuracy is improved. If the papers should be fed by relatively a large amount, the paper feeding speed can be accelerated.
