Title: Amorphous silicon solar battery and its manufacture
Inventor: NAGASAWA TAKESHI
IPC: H01L31/04
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To increase an effective surface area of a solar battery against a substrate area to increase the current output by forming semi-spherical dimples on the surface of a glass substrate to be used. SOLUTION: Amorphous silicon solar battery element has such a structure that a transparent electrode film 02, an amorphous silicon film 03, and a metal electrode film 04 are stacked on a glass substrate 01 formed with semi-spherical dimples. If necessary, a protective film 05 can be formed on the metal electrode film 04. The use of the glass substrate 01 having dimples increases the current output by about 1.2 times compared with a case wherein a flat glass substrate is used. By forming the semi-spherical dimples on the glass substrate 01, an effective surface area is increased, thereby increasing the current output. This effect is not one derived from the material, shape, etc., of the transparent electrode 02 and therefore the transparent electrode can be of any shape and material.

Title: Safety device for combustion apparatus
Inventor: IMAJIMA MITSUHIRO
IPC: F23N5/00
Filed: 1981-02-16
Abstract: PURPOSE:To improve a partial pressure detecting precision and to increase prevention of oxygen shortage or other safety, by constituting a device such that an oxidized semiconductor element, whose resistance value is changed by an oxygen partial pressure, is mounted in a combustion exhaust gas path pipe, and the detecting output drives a safety device. CONSTITUTION:Combustion exhaust gas flows in a pipe 14 like an arrow mark shown in a dotted line. An element 15, consisting of an oxide semiconductor, whose main component is SnO2, having a resistance value changed by an oxygen partial pressure, is arranged in the pipe 14, and thereby an output resistance value from a terminal 16 fluctuates according to a concentration of reducing gas such as CO in exhaust gas. As a result, an output resistance value is steady during the perfect combustion, but when it is brought to an oxygen starvation state, the output resistance value of the terminal 16 reduces extremely. Thus, when it reaches an critical oxygen starvation range, a safety device operates. In this way, a change in oxygen partial pressure can be detected highly precisely, and this permits the improvement of detection precision of an oxygen starvation state and the safety is increased.
