Title: Manufacture of solar cell
Inventor: NISHIKAWA TAKESHI
IPC: H01L31/04
Filed: 1986-01-23
Abstract: PURPOSE:To improve the photoelectric effect of a solar cell further while various advantages, such as workability, waterproofness, light resistance, etc. are utilized by conducting baking forming a P-type semiconductor layer by CdTe in an inert gas atmosphere containing not more than 1mol% oxygen. CONSTITUTION:An atmosphere in which not more than 1mol% oxygen to the usage of an inert gas (nitrogen gas) is contained to said inert gas is manufactured, and baking shaping a P-type semiconductor layer at the formation of the P-type semiconductor layer in a solar cell layer is conducted in the atmosphere. Oxygen atoms enter into the crystal lattice of CdTe from the viewpoint of crystal size, the electron density of said CdTe is lowered, and the state in which one valence electron is insufficient, the state in which a hole is generated, is brought. That is, oxygen atoms function as an acceptor for supplying holes, and positively change said CdTe into a P-type. When not less than 1mol% oxygen is mixed in the inert gas, there is possibility in which the excess oxygen, on the contrary, oxidizes CdTe.

Title: Safety device for fixing unit
Inventor: WATABE TAKAHIRO
IPC: G03G15/20
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To surely prevent a thermal fixing means from firing and fuming because it is abnormally heated by driving a pressure means based on the detection of the temperature of the thermal fixing means rises from the prescribed temperature and making the thermal fixing means press-contact with a stop means. SOLUTION: A CPU 6 transmits a pressure driving command signal to a pressure driving circuit 10 when a digital signal which is transmitted from an A/D conversion circuit 5 shows that the temperature of a fixing roller 1 rises from the controlled temperature though a heating driving command signal transmitted to a heater driving circuit 7 is turned off. When the pressure driving command signal is transmitted from the CPU 6, the roller 1 is driven by the driving circuit 10 by supplying prescribed electric power to a push-pull solenoid so that the roller 1 is made to press-contact with a thermoswitch 9. Then, the roller 1 is shifted in a direction shown by an arrow V and made to press- contact with the switch 9.  Thus, the temperature of the switch 9 immediately arrives at the cut-off temperature set to be lower than the controlled temperature so as to stop the heating of the roller 1 by a heater 2 by cutting off an AC power source line.

IPC: G02F1/1335
Filed: 1991-02-04
Abstract: PURPOSE:To provide the liquid crystal display body consisting of a high-polymer/liquid crystal composite film (hereafter abbreviated as PDLC) which is bright and does not require a back light by forming many layers of metallic thin-film layers on reflection electrodes and using these layers as interference layers to prevent the electrodes from acting like mirrors. CONSTITUTION:This element has a reflection film 8 on one side of the PDLC 1 and is further laminated with many layers of the metallic thin-film layers 10 on this reflection plate 8 in such a manner that these films are commonly used as the electrodes. The interference effect by the metallic thin-film layers cannot be expected while voltages are not impressed to the PDLC 1 and, therefore, the display element is white. The PDLC 1 becomes transparent when the voltage is impressed to the PDLC 1 to put the PDLC into a light transparent state. Visible light, therefore, arrives at the metallic thin-film layers 10 and the interference meeting the number of layers and film thicknesses of the formed metallic thin-film layers 10 and the refractive indices of the constituting metals thereof takes place and these layers are colored. The layers turn black to dark purple if optimum conditions are selected. Namely, the black to dark purple display is possible if the voltage is impressed.
