Abstract: PROBLEM TO BE SOLVED: To simplify an exhaust gas discharge pipe and sufficiently purify exhaust gas by installing a honeycomb structure body, which has a large number of cell holes coated with a titanium dioxide coating to be radiated with light rays of an ultraviolet lamp, in the inside of a muffler of an automobile. SOLUTION: A honeycomb structure body 4 having a large number of cell holes 4a formed by extrusion molding of clay or a fine ceramic is installed in the inside of a muffler. The inner surface of each cell hole 4a is coated with a thin film of titanium dioxide. Ultraviolet rays are efficiently radiated to the respective cell holes 4a, 4a from an ultraviolet lamp 5 installed in the outer circumference of an exhaust gas pipe 2 in the upstream side of the muffler 3. An inversely turning-back wall 6 is formed in the downstream side of the honeycomb structure body 4 and an exhaust gas passing through the exhaust gas pipe 2 in the direction shown as an arrow is turned back by the inversely turning-back wall 6 and passed through the respective holes 4a, 4a and discharged out of a discharge outlet 8 via an outside route 7.  By turning on the ultraviolet lamp 5, NOx and SOx of the exhaust gas passing through the cell holes 4a are efficiently oxidized and decomposed to harmless carbon dioxide gas and other gases by the strongly oxidizing performance of titanium dioxide.

Patent JP-H04364079-A (JP)
Title: Semiconductor device
Inventor: YAMADA KATSUMI
IPC: H01L21/223
Filed: 1991-06-11
Abstract: PURPOSE:To prevent deterioration of characteristic due to the appearance of charges by forming an outer most surface layer having a first conductivity type and high impurity concentration to the region other than that having the second conductivity type in the low impurity concentration region. CONSTITUTION:A thin N layer is formed at the surface of a N<-> layer 2. A diode having the dielectric strength of 60V to 900V is fabricated using a silicon substrate having an N<-> epitaxial layer 2 of various impurity concentrations. In the diode having formed an N layer 12 having impurity concentration of 5X10<15>/cm<2> and diffusion depth of 1mum, operation life is extended. However, if impurity concentration of the N layer 12 is too high or diffusion depth is too deep, extension of depletion layer is remarkably interfered when an inverse bias is applied across an anode electrode 5 and a cathode electrode 6. Therefore, dielectric strength is lowered and it becomes difficult to suppress the surface sensitivity. In other words, the effective concentration range of the N layer 12 is 1X10<15> to 1X10<16>/cm<2> and diffusion depth range 18 0.2 to 2mum.

IPC: G03G21/00
Filed: 1989-05-31
Abstract: PURPOSE:To obtain an excellent copy image at low cost by controlling a voltage applied to a shield case and varying the surface potential of a photosensitive body. CONSTITUTION:A document image is formed to form an electrostatic latent image on the surface of the photosensitive body 10 and a developing device 12 sticks toner to develop the latent image. The toner image is transferred to a form by an electrostatic charger 13 for transfer. Then the form is peeled by an electrostatic charger 14 for peeling. Then toner remaining on the photosensitive body 10 is cleaned by a cleaner 15 and the photosensitive body 10 is discharged electrostatically by an electrostatic discharging lamp 16. Then when a photo mode is set, a switch 20 is switched to earth the shield case 11 of a corona discharger 11 and part of the discharging voltage from the discharger 11 becomes a current, which flows to the earth through the shield case 11b. The surface potential of the potosensitive body 10 falls to reproduce half-tones of a copy document, thereby obtaining an excellent copy image. Thus, the voltage applied to the shield case 11b is controlled to vary the surface potential of the photosensitive body 10, thereby obtaining the excellent copy image.

Abstract: PURPOSE: To prevent contamination by the adhesion of flux to a suction head, when the flux is fed to solder balls sucked to the suction head, by disposing a resisting plate for imparting fluid resistance to the flux at a flux supply section. CONSTITUTION: A resisting plate 16 is disposed at a flux supply section 102. A suction head 4 moves to the flux supply section 102.
