Title: Production of optically active 1,3-butanediol
Inventor: MATSUYAMA AKIKAZU
IPC: C12R1/64
Filed: 1989-04-26
Abstract: PURPOSE:To obtain the title high-optical purity product by highly economical, simple means by asymmetrical reduction of 4-hydroxy-2-butanone using microorganisms and collecting the resultant optically active 1,3-butanediol. CONSTITUTION:A culture solution of microorganisms such as brevibacterium iodinum put to culture in a medium comprising a carbon source such as glucose and a nitrogen source such as ammonium chloride is either directly used or, after separation of the bacteria contained, is suspended in a buffer or water again. And 4-hydroxy-2-butanone either directly or in the form of an aqueous solution or organic solvent solution is added to the resultant suspension, followed by making an asymmetrical reduction at 10-60 deg.C. Thence, the resulting optically active 1,3-butanediol can readily collect either directly from the liquid reaction system or, after separating the bacteria contained, by using a conventional purification technique with an organic solvent. Thereby the objective high-optical purity product can readily be obtained; therefore, this process is industrially highly advantageous.

Abstract: PURPOSE: To obtain a transistor small in power loss by forming a 3rd collector region of high concentration on the regions of a 1st and 2nd collectors along the shape of a depletion layer from a gate region.  
     CONSTITUTION: At the part facing at least an emitter region 4 on the interface between a collector n +  region 1 and a collector n -  region 2 a collector region 11, that is of the same conductive type as the collector n -  region 2 and is higher in concentration, for instance, is of the same concentration as that of the colletor n +  region 1 is formed along the shape of a depletion layer extending from gates 31. Usually, the higher the concentration of the collector 2 is, the greater the maximum working current becomes and the smaller the voltage drop becomes, on the other hand, the extension of the depletion layer is restrained and the withstand voltage becomes worse. However, in this way the depletion layer extends only in the collector 2 at a B-B' section and becomes highly pressure-tight. And at an A-A' section the resistance region disappears or decreases and as a result of it electric power loss can be reduced.
