Title: Exhaust particulate purifying device of internal combustion engine
Inventor: TOMITA KENJI
IPC: F01N3/02
Filed: 1994-06-06
Abstract: PURPOSE:To prevent generation of the abnormal high temperature causing cracks on a filter in regenerating in a catalyst holding filter for filtering exhaust particulates in an internal combustion engine. CONSTITUTION:Since, transferring heat to be carried by exhaust gas from the upstream side and combustion heat to be generated after particulates deposited on a part (a) on the upstream side are burnt besides reaction heat to be generated after unburnt fuel in exhaust gas generates oxidative reaction by a catalyst, 41 held by the filter are all-owed to flow to the part on the downstream side of a filter 4, particularly, the temperature in the center part (c) reaches the abnormal high temperature, thereby there is a possibility that cracks and welding damage are generated. Therefore, any catalyst is not held on the center part (c) on the downstream side, depending on the case, only coating materials are applied thereon. Accordingly, the speed of oxidative action of fuel on the part is reduced, as a result, the abnormal high temperature is not generated on all parts of the filter 4, thereby deposited particulates are suitably heated anywhere and ignited and burnt. Moreover, the outer peripheral part (b) on the downstream side is not exposed to the abnormal high temperature by radiating of heat to the periphery.

Abstract: PURPOSE:To eliminate the need for fine machining, to improve the yield and to reduce the cost by using an optical shutter array which is made of a translucent material with electrooptic effect and deflects the optical path of incident light through the operation of an irregular electric field to perform shuttering operation. CONSTITUTION:When the irregular electric field is made to operate on the optical shutter 41 in the optical printing head used with the optical shutter array 40, a refractive index distribution is generated in the optical shutter 41 made of the translucent electrooptic material with electrooptic effect and the optical path of the incident light is deflected through the operation of the refractive index distribution. Then respective optical shutters are turned on and off by making the irregular electric field operate or not operate on the respective shutters 41 of the optical shutter array 40, thereby writing data on a photosensitive body, etc., by the optical printing head. Consequently, the driving voltage of each optical shutter can be lowered, and the machining is not necessary; and the yield is improved and the cost is reduced.

Title: Method and device for laser cutting
Inventor: KITAGAWA NAOAKI
IPC: B23K26/14
Filed: 1995-04-25
Abstract: PURPOSE: To smoothly finish a cut surface simultaneously with the completion of a cutting operation by cutting a work while blowing a mixed gas towards the cut opening end on the rear side of the work and thereby preventing dross from sticking or a sharp cut surface from remaining on the rear side of the work. CONSTITUTION: A metal forming the rear cut opening 18 of a work 15 is combined with oxygen preferentially by the action of oxygen in a mixed gas to form an oxidized film on the end of the opening 18. The oxidized film has a high absorptivity of a laser beam; therefore, if the rear cut opening end 18 of the work 15 is selectively heated up with the use of the high laser absorptivity, the particular place of the work is molten. In addition, by the jetting force of the mixed gas jetted towards the molten place, dross is isolatedly diffused from the rear of the work 15, smoothing the cut opening end of the work 15 and making it easy to obtain a product agreeable to the touch.

Abstract: PURPOSE:To surely and continuously record time information or address information by recording time information or address information from a value following an already recorded value at the time of detecting the presence of already recorded information and inhibiting recording at the time of detecting the absence of already recorded information. CONSTITUTION:A microprocessor 1 discriminates whether the start position of tape recording is the start position or the halfway position of the tape according as detecting the start position of the tape just before recording or not, and the processor 1 controls recording from the initial value of time information or address information when discriminating the start position of the tape. The processor 1 reproduces the tape running stop state when discriminating the halfway position of the tape, and it is detected by an envelope detector 8 whether already recorded information exists in the start position or not. When the presence of already recorded information is detected by the processor 1, recording starts with a value following the already recorded value of time information or address information; and when the absence is detected, recording is inhibited. Thus, time information or address information is surely and continuously recorded.
