Title: Image sensor
Inventor: KUWANO YUKINORI
IPC: H04N5/335
Filed: 1987-10-20
Abstract: PURPOSE:To simplify a manufacture process and reduce a cost by a method wherein an image read part composed of an optoelectric transducer and a display function of read images are provided in one substrate and the same semiconductor material and conductive material are employed for both the optoelectric transducer and the active element of the display function. CONSTITUTION:A thin film 7 of semiconductor material such as amorphous semiconductor whose main component is Si is sandwiched between a transparent electrode 8 made of indium oxide, tin oxide or the like and an electrode 9 made of metal such as Al, Ti, Cr, Ni, Ag or Au to form an example of an image read part 3. On the other hand, an image display part may be, for instance, a liquid crystal display of an active matrix driven by an active element 10 employing a thin film transistor. When the thin film transistor is employed, the material of the transparent electrode 12 of the picture element is the same as the material of the transparent electrode 8 of the image reading part 3, the material of the semiconductor layer 11 of the thin film transistor is the same as the material of the thin semiconductor film 7 of the image read part 3 and, further, the material of source and drain electrodes 13 and 14 is the same as the material of the light shielding electrode 9. With this constitution, as the same material can be applied in the same process, the manufacturing process can be simplified and the cost can be reduced.

IPC: H01M8/02
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To suppress drop in cell characteristic caused by increase in polarization caused by excess replenishing of an electrolyte by replenishing the electrolyte every unit cell in a high temperature operation state.

Title: Exhaust emission control device for internal combustion engine
Inventor: SUZUKI HIROMI
IPC: F01N13/02
Filed: 1990-10-01
Abstract: PURPOSE:To prevent the abnormally high temperature of an upstream catalyst body and avoid the shortage of oxygen by introducing the secondary air by utilizing the negative pressure, by forming a communication passage, making a detour around the upstream side catalyst body, and forming a secondary air introducing hole in the vicinity of the communication passage. CONSTITUTION:When exhaust gas flows to the vicinity of the upstream side catalyst body 13 in an expansion pipe 11b, almost all the parts flow out, passing through the inside of the reaction hole 13f of a monolithic catalyst 13a. Further, the rest exhaust gas flows into a communication passage 13g from an exhaust gas passing hole 13e. Accordingly, almost all the parts of the exhaust gas is purified through the catalytic reaction with the upstream side catalyst body 13, during passing through the reaction hole 13f. Since, in this case, the flow passage area of the communication passage 13g is relatively small, the flow speed of the exhaust gas is accelerated, and a negative pressure is generated inside the communication passage 13g. Accordingly, the secondary air which is purified by an air cleaner flows into the communication passage 13g from a secondary air introducing hole 11i. Accordingly, the unreacted exhaust gas is purified during passing through the reaction hole 14e of a downstream side catalyst body 14, together with the secondary air.
