Title: Exhaust emission control device for internal combustion engine
Inventor: OGAWARA SEIJI
IPC: F01N3/24
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To establish a high NOx controlling rate even in the low temperature of exhaust gas by allowing a reducing agent to contain a component having a raised low temperature oxidizing ability in the early stage of an engine to which the reducing agent is supplied by a reducing agent supply means at every predetermined internal in the previous stage of an oxidation catalyst. SOLUTION: During running of an engine 1, a predetermined amount of light oil or the like as a reducing agent is added to exhaust gas through a first reducing agent supply valve 5 and a reducing agent injection valve 7 by a controller 11 in predetermined timing to burn the reducing agent with an oxidation catalyst 3 and form primarily the rich atmosphere. Then, when exhaust gas temperature is higher than a predetermined value (for example 150 deg.C), only usual reducing agent such as light oil is added in the addition of the reducing agent. On the other hand, when the exhaust gas temperature is not higher than the predetermined valve, low temperature active species are adapted to act on light oil or the like as a so-called ignition agent and burn sufficiently the light oil or the like so that NOx controlling performance in the low temperature of the exhaust is prevented from lowering.

IPC: G11B7/09
Filed: 1987-07-23
Abstract: PURPOSE:To execute an exact focus servo-operation without being influenced by the fluctuation of the light quantity in a pre-bit part, by switching a gain of a focus servo-circuit, based on the reflected light quantity from an optical disk. CONSTITUTION:A focus error signal takes the sum of a diagonal element of a quadri-sected photodetector QPD by adders 12, 13 and obtained as its difference signal. Subsequently, it passes through a focus phase compensating circuit 18, and inputted to a focus gain switching amplifier 22. On the other hand, a sum signal of the diagonal element of the detector QPD and an output signal of a bi-sected photodetector DPD are inputted to adders 15, 17 and an output VP corresponding to the whole light quantity from an optical disk is outputted through an adder 20. Next, the output VP is inputted to a comparator 23, and when it exceeds a prescribed threshold level, the gain of the amplifier 22 is lowered. In such a way, a stable focus servo in a pre-bit part can be executed.

Title: Wire cut electric discharge machining device
Inventor: IWASAKI TAKESHI
IPC: B23H7/06
Filed: 1982-10-20
Abstract: PURPOSE:To correctly detect the discharge start position and automatically set the machining condition preventing the open circuit of a wire electrode when the discharge is started by detecting the contact position between the wire electrode and a work by means of a detection mechanism. CONSTITUTION:A contact detection mechanism 30 compares the interelectrode voltage Eo from a DC power supply 32 applied across a work 10 and a wire electrode 14 with the comparison voltage Ec from a comparison voltage power supply 34 by means of a comparator 36. When the electrode 14 is brought into contact with the work 10 and the voltage Eo is reduced to the voltage Ec or lower, a contact detection signal is generated by the comparator 36 and fed to a numerical control unit 38. Thereby a shift stop command of the electrode 14 is generated by the unit 38 to stop the shift of the electrode 14, which is then shifted backward so as to form a predetermined discharge machining gap between the electrode 14 and the work 10, thus the machining condition is set to the extent capable of preventing the open circuit of the electrode 14.
