Filed: 1990-11-08
Abstract: PURPOSE:To set the valve opening and closing timing at an optimum desired timing constantly by controlling linearly a rotation phase converting means to convert the rotation phase of a camshaft with two oil pressure control valves which are duty-controlled. CONSTITUTION:An electronic control device 12 calculates the control object value of a camshaft 14 depending on the operation condition of the engine 11. And the valve opening and closing timing of the present condition is detected by the output signals of a crank position sensor 15 and a cam position sensor 16, and it is compared with the control object value to determine the rotation phase converting amount of the camshaft 14. Furthermore, the electronic control device 12 duty-controls the first and the second oil pressure control valves 24 and 25. When the valve opening and closing timing is advanced from the present condition, for example, the first oil pressure control valve 24 is controlled after the second oil pressure control valve 25 is fully closed. As a result, a high pressure oil discharged from the second hydraulic pump 22 is fed to an operation line 28, and this pressure operates to an oil pressure chamber 37. Consequently, a ring-form piston 31 is moved to convert the rotation phase of a timing pulley 30 and the camshaft 14.

Filed: 1986-12-22
Abstract: PURPOSE:To prevent the lowering of a photoelectric conversion efficiency when parts of a low-resistance intermediate layer-including semiconductor layer, which is formed on isolated electrodes on the same substrate, of a multijunction structure are removed by a method wherein the average amount of O in the intermediate layer of a prescribed width from the removed end surfaces is held at a prescribed value. CONSTITUTION:Transparent electrodes 2 are each isolatedly formed on a glass substrate 1 and p-type, i-type and n-type amorphous Si layers 3-5 are made by a glow discharge decomposition method, wherein SiH4 and the mixed gas of the SiH4 are used. Then, an Mo intermediate layer 10 is deposited and p-type, i-type and n-type amorphous Si layers 6-8 are superposed in reverse order. Then, by removing partially the semiconductor layer while O2 is sprayed along the optical axis of laser light using a Q-switched YAG laser, the average amount of oxygen in the intermediate layer up to 100 Angstrom  from the removed end surfaces is 0.5-10 atoms or more. According to this constitution, as the average amount of oxygen in the vicinities of the end surfaces of the intermediate layer is high, a leak is inhibited through the intermediate layer.
