Filed: 1983-05-24
Abstract: PURPOSE:To prevent effectively a knock pin from dropping out of a piston in high temperature by making the knock pin of austenite system stainless steel which prevents a piston righ fitted in the aluminum alloy piston from turning. CONSTITUTION:An aluminum alloy piston 1 is formed on the outer peripheral surface with an annular groove 3 in which a knock pin hole 5 is radially formed in the form of a blind hole. A knock pin 2 of austenite system stainless steel is fitted into this pin hole 5 with an interference delta. The piston ring 4 is formed on the back corners of a slit 4b with arcuate notches 4a. And the piston ring 4 is fitted in the annular groove 3 with the notches 4a being aligned with the knock pin 2. Thus, since the difference of expansion coefficient between the knock pin 2 and the piston 1 can be maintained small, the interference delta remains even in high temperature of the piston 1 to prevent the pin 2 form dropping out.

Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To reduce NOx in combustion exhaust gas effectively in a wide temperature range and to attain a high NOx removal ratio by passing the exhaust gas containing oxygen, water vapor, and NOx through a catalyst layer in which Pd and Rh are supported on H-MHI type zeolite. SOLUTION: Combustion exhaust gas containing oxygen, water vapor, and NOx from combustion equipment A of city gas, etc., is passed through a catalyst layer C in which Pd and Rh are supported on H-MFI type zeolite via an exhaust gas conduit B. NOx in the exhaust gas is reduced into N2 by the catalyst of the layer C to be discharged as gas containing H2 O, O2 and N2 from a discharge conduit D. In this way, NOx in the exhaust gas can be removed effectively in a wide temperature range of about 340-570 deg.C. Since a good NOx removal effect is obtained even in the presence of oxygen and water, exhaust gas from a lean-burn system can be applied effectively.

Filed: 1988-04-14
Abstract: PURPOSE:To connect the picture reader to a host computer with a different picture data processing speed by varying the read speed in response to the stored data quantity of a read data buffer. CONSTITUTION:The read speed of an original is varied by a read speed variable means. Then the picture data of the read original is once stored in a read data buffer 20a and read at a prescribed speed determined by a host computer 21 connected to the picture reader and sent to the host computer 21. When the transmission speed to the host computer 21 is slower than the read speed of the original and the picture data quantity not sent yet in the read data buffer 20a is increased over a specified value, the read speed of the original is decreased. Thus, the picture reader is connected to a host computer with a different picture data processing speed without providing a picture memory to the host computer 21.
