Title: Manufacture of solar battery
Inventor: ABE MASANARU
IPC: H01L31/18
Filed: 1985-02-12
Abstract: PURPOSE:To obtain a solar battery, whose efficiency is improved, by specifying the regulation of the temperature of a furnace in a diffusion process in the manufacture of the solar battery. CONSTITUTION:In a vapor diffusion process, a silicon ribbon crystal substrate is set in a diffusion furnace, whose temperature is set at 600 deg.C. Then, the furnace temperature is increased to the specified value of 800-1,200 deg.C at a temperature gradient of 200 deg.C/H or less. A PSG film and a p-n junction are formed at the specified temperature of 800-1,200 deg.C. The furnace temperature is decreased to 600 deg.C at a temperature gradient of 50-200 deg.C/H. The silicon ribbon crystal substrate, whose p-n junction is formed, is taken out. Thus, the solar battery, in which the p-n junction is formed, is obtained without deteriorating the crystalline property and the electric characteristics of the silicon ribbon crystal substrate.

Title: Medium detector using optical fiber sensor
Inventor: TERAMURA KOJI
IPC: G07D7/06
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus difficult to receive the external noise with a simple structure by constituting a plurality of optical fiber sensors of a single light-emitting element while connecting the respective optical fiber sensors to the elements through a single optical fiber. SOLUTION: In a medium detecting apparatus 27, a plurality of optical sensors S1-S7 can be constituted of a single light-emitting element 29. The respective sensors S1-S7 can be connected to the element 29 through an optical fiber 31, so that the number of wiring can be reduced. Since the sensors are constituted of one element 29, a light-emitting circuit can be mode single. Since the element 29, the sensors S1-S7 and light receiving elements 37 can be connected respectively through the optical fiber, the signal optical transmission with low loss is enabled, while these members can be made difficult to receive external noise. Thus, the detection is enabled even if a distance between the control circuit and the positions of the sensors S1-S7 is long.  Since the most portion of the transmission path transmits the signal through the optical fiber 31, the transmission time can be shortened.
