Abstract: PURPOSE: To enable formation of a high density base area and a high density emitter area as close as possible by a simple manufacturing process without requiring a special equipment by etching the sidewall of a nitride film by using a double layer consisting of a low temperature oxide film and a 2nd nitride film and self-matching the emitter of bipolar transistor(TR). CONSTITUTION: A 2nd nitride film layer 26 consisting of Si3 N4 is formed on the whole surface of a substrate, a 6th low temperature oxide film layer 27 is formed on the upper part of the layer 26 and then a heat processing process for improving the density of the layer 27 is executed. Then, regions except for the region for forming an emitter are etched by a photolithography process to form an emitter area, a photomask 28 is formed to form a 2nd base and boron ions are implanted by proper energy to form a 2nd base ion-implantation area 29. When the 2nd nitride film is etched by phosphoric acid solution after removing the photomask 28, the sidewall of the 2nd nitride film is etched.  Consequently a high density boron area 29 on the 2nd base side and a high density N-type emitter area to be formed after the formation of the area 29 are formed so as not to be directly brought into contact with each other.

Abstract: PURPOSE:To quickly perform potential control so as to prevent large variation of the electrifying capacity of a photosensitive body, by setting a parameter to be used for controlling a latent image forming condition corresponding to the detected temperature of the photosensitive body. CONSTITUTION:A photosensitive body 1 is at first, uniformly charged with an electrifier 2 and is subjected to destaticization in accordance with a picture by means of picture exposure 3. As a result, a latent image is formed and developed to a visible picture with a developing device 4. The visible toner picture is transferred to a transfer material 6 by means of transferring electrifier 5 and the non-transferred toner is cleaned by a cleaner 7. Thereafter, the photosensitive body 1 is further subjected to uniform destaticization by preexposure 8. Thus one picture forming cycle is completed. By previously measuring the atmospheric temperature T' by using an external temperature sensor, the surface temperature of the photosensitive body 1 measured by a temperature sensor 10 is adjusted with a drum heater 11 by using the external temperature as a reference. Therefore, the environmental stability of the surface potential control of the photosensitive body can be greatly improved and the reliability of control can be increased.

Title: Low-calorie food additive
Inventor: NITSUCHI YASUTAKE
IPC: A23L33/20
Filed: 1987-09-25
Abstract: PURPOSE:To suppress bitterness and sweetness eliminating action and to improve taste of extract obtained from leaves of Gymnema sylvestre, having specific actions of leaves, by subjecting the extract to removal treatment of bitter and sweet components. CONSTITUTION:Raw leaves of Gymnema sylvestre belonging to the family Asclepiadaceae native in India are air-dried at normal temperature for about 7 days and the dried leaves are fed to a roaster and roasted to give coarse tea. The coarse tea is immersed in hot water at about 90 deg.C to prepare a tea solution, which is concentrated. Then the concentration solution is freeze-dried to give an extract. Then the extract is subjected to reversed phase column for high performance liquid chromatography to partially collect a fraction component eluted with about 40% methanol. Then the fraction is freeze-dried to give a low-calorie food additive. Consequently, the additive has both inhibitory action on rise of blood sugar value and cariostatic action and will not change the taste of foods and drinks because of weak action on elimination of sweetness and low bitterness. Therefore, the additive is added to a food such as glucide or starch to give great welfare.
