Title: Air-fuel ratio controller for internal-combustion engine
Inventor: KOBAYASHI NOBUYUKI
IPC: F02D41/08
Filed: 1984-04-27
Abstract: PURPOSE:To prevent the variation of revolution speed and generation of vibration due to the reduction of idle revolution speed by suspending the closed-loop control for air-fuel ratio and carrying-out opened-loop control when the revolution speed in idle operation is below a prescribed revolution speed. CONSTITUTION:A closed-loop control means (d) for air-fuel ratio detects the concentration of O2 in exhaust gas by using a specific-component concentration detecting means (b) consisting of an O2 sensor, and feedback-controls the air- fuel ratio of the mixed gas supplied into an internal-combustion engine (a) to the theoretical value. An idle state detecting means (c) detects idle state, and the closed-loop control for air-fuel ratio is continued. When the engine revolution speed detected by a revolution-speed detacting means (e) becomes below a prescribed value, the closed-loop control is switched to the air-fuel ratio control in opened loop by an opened-loop control means (f). Therefore, the variation of the number of revolution and generation of vibration in low revolution speed can be prevented.

Title: Ofdm communication apparatus and synchronization timing detecting method
Inventor: SHIRASAKI YOSHIMASA
IPC: H04J11/00
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To detect exact symbol synchronization timing by providing an updating means for updating a first threshold to the result of correlation when the result of correlation exceeds the first threshold and an estimating means for estimating the maximum value of an updated second threshold or the like. SOLUTION: In a symbol synchronization timing detecting part 108, the result subtracting a correlative level detection threshold stored in a correlative level detection threshold storage part 1081 from a correlative value output from an envelope generating part 107 by a subtracter 1083 is outputted to a maximum value estimating part 1082. In the maximum value estimating part 1082, a correlative level detection threshold updating signal is outputted from the output from the subtracter 1083 to the correlative level detection threshold storage part 1081. Thus, since the timing exceeding the correlative level detection threshold is defined as symbol synchronization timing, a real maximum value can be detected and exact timing can be detected.

Abstract: PURPOSE:To obtain a crystal with a uniform film thickness and a uniform film composition by a method wherein a reflecting means which reflects a thermol radiation emitted from the surface of a sample so as to apply the reflected radiation to the sample surface is provided in a vapor growth equipment. CONSTITUTION:Eddy currents are induced in a susceptor 2 by a radio frequency current applied to a radio frequency coil 3. The susceptor 2 is heated by the induced eddy current. Substrates 6 attached to the susceptor 2 are heated by heat conduction. Heat rays are emitted from the surfaces of the substrates 6. The thermol radiation are reflected by mirrors 5 attached to the coil 3 and partially returned to the substrates 6. The end parts of the substrates 6 which have lower temperatures than the center parts are heated again by the reflected thermol radiation and the temperature of the substrate 6 becomes uniform. Reactive gas supplied from a supply inlet 1 is decomposed and made to react to make crystal growth. As the temperature of the substrate 1 is uniform, the uniformity of the film thickness and composition of the crystal made to grow can be obtained.
