Title: Air-fuel ratio control device for internal combustion engine
Inventor: KASHIWANUMA NOBUAKI
IPC: F02P17/12
Filed: 1989-10-26
Abstract: PURPOSE:To discriminate the misfire of an engine ignition system from that of a fuel system so as to facilitate the disposal of a failure by judging the misfire of the engine ignition system at the time of the auxiliary air-fuel ratio correction quantity reaching the lean side limit value, and displaying this. CONSTITUTION:When misfire is generated to an ignition system, unburnt gas and residual air are exhausted from a misfired cylinder even if the air-fuel ratios of all the cylinders are theoretical air-fuel ratios, so that an upstream side air-fuel ratio sensor performs lean output, and the main air-fuel ratio correction quantity is operated onto the rich side by a main air-fuel ratio correction quantity operating means and adjusted onto the rich side by an air-fuel ratio adjusting means. Influenced by this, a downstream side air-fuel ratio sensor performs rich output, so that an auxiliary air-fuel ratio correction quantity operating means operates the auxiliary air-fuel ratio correction quantity onto the lean side, and at the time of the auxiliary air-fuel ratio correction quantity reaching the lean side limit value MIN, an ignition system misfire display means judges the generation of misfire due to the abnormality of the ignition system and displays it accordingly. The misfire caused by the abnormality of the ignition system can be thus discriminated positively from that caused by the abnormality of a fuel system, thereby facilitating the disposal of a failure and preventing catalyst degradation.

Title: Temperature-characteristic measuring device of semiconductor laser
Inventor: KAWARATANI MASAHIKO
IPC: H01L21/66
Filed: 1984-12-27
Abstract: PURPOSE:To perform measurement in a short time and to change the temperature of an element readily by only changing the current of the element, by the constitution, wherein time for increasing element temperature depends only on the thermal time constant of the element. CONSTITUTION:When a current I exceeds a threshold current value Ith of a semiconductor laser, a light output Po is rapidly increased and laser oscillation is started. At this time, when the temperature of an element is increased from a temperature Ta to a temperature Tb, the threshold current value Ith is increased. Instead of observing the temperature characteristic of Ith, the temperature characteristic of an operating current Iop at the constant light output Po is measured. At this time, when the light output Po is made sufficiently small, a large error is not yielded. As a means for heating the element, an operating current Iop2 corresponding to the specified to the specified light output Po1 is made to flow during a heating period from an element time t1 to t2; and an operating current Iop1 required for the specified light output is made to flow during a measuring period from a time t2 to t3. Then, the heating period (t1-t2) is made sufficiently longer than the thermal time constant of the element. Meanwhile, the measuring period (t2-t3) is made sufficiently shorter than said thermal time constant.

Title: Servo controller
Inventor: SAWA EIJI
IPC: G05B19/414
Filed: 1992-10-15
Abstract: PURPOSE:To improve the degree of freedom in use by eliminating the necessity to combine master and slave control sections and individually controlling the slave according to an object for servo control. CONSTITUTION:When a start command is sent from a master control section 20 to a timing generation section 31, an interrupt signal is sent from the timing generation section 31 to a master control section 20 and at least one slave control section 30. Accepting the interrupt signal, the master control section 20 executes the position control for an object 1 for servo control. The slave control section 30 executes either or both of the speed control and current control. Therefore, the interrupt signal between the master and slave control sections 20 and 30 can be the position control only. If no position control is required, either or both of the speed and current control for the slave control section 30 is executed.

Title: Nonvolatile semiconductor memory
Inventor: HAYASHIGOE MASANORI
IPC: G11C17/00
Filed: 1990-10-15
Abstract: PURPOSE:To shorten detection and deletion time by repeating deletion pulse application until a memory transistor becomes over deletion and applying high voltage to a word line when the over deletion is detected, and pouring electron to a floating gate with tunnel phenomenon. CONSTITUTION:In the case of detecting the over deletion, the power supply voltage is applied to the sources of the transistors 20, 21, 30, and 31 by a high voltage/power supply voltage changeover circuit 37, and a source line 9 is grounded by a high voltage/ground voltage changeover circuit 10. An AH and a TP become 'L', an EV becomes 'H', word lines 5 and 6 become high voltage, Y gate lines 13 and 14 become 'L'. Therefore, the threshold value becomes high while the electron is poured to the floating gate of all the memory transistors by the tunnel phenomenon, and a memory transistor turns from depression to enhancement. Thus, the nonvolatile semiconductor memory with short deletion time can be obtained.

Abstract: PURPOSE:To make the thickness of a coat film uniform and prevent the generation of cracks, etc., in the film, by providing a wafer cooling means at the periphery of a wafer stage. CONSTITUTION:Liquid nitrogen is sent being gasified, from a plurality of liquid nitrogen intakes 7 provided in the vicinity of a wafer stage 2, to cool a wafer 6 and the stage, etc. And, the gasifying speed of a coating solution made by dissolving a silicon compound in a solvent such as alcohol, etc., becomes extremely small by cooling the wafer 6, as the gasifying speed of an organic solvent, ethyl alcohol for example, in the coating solution to be dropped on to the wafer 6 surface from a dripping nozzle 3 has a tendency to become greater as temperature rises. Accordingly, it becomes possible to form a film of the silicon compound slowly on the surface of the wafer 6. And, this makes the coat film have a uniform thickness and prevents the generation of cracks.
