It is an object of the present invention to provide a method for manufacturing a semiconductor layer, a method for manufacturing a photoelectric conversion device, and a semiconductor layer forming solution which are able to easily manufacture a good semiconductor layer having a desired thickness. To accomplish this object, a starting solution containing a metallic element, a chalcogen organic compound and a Lewis base organic compound is initially produced. Next, heating the starting solution produces fine particles. The fine particles contain a metal chalcogenide which is a compound of the metallic element and a chalcogen element included in the chalcogen organic compound. A semiconductor layer is formed by using a semiconductor layer forming solution in which the fine particles are dispersed.

A receiver includes a first receiving section, a second receiving section, and a controller. A controller is operable to switch between a diversity receiving mode in which both of the first receiving section and the second receiving section are activated and a single receiving mode in which the first receiving section is activated while the second receiving section is deactivated. The controller allows the first mixer to heterodyne the signal output from the first RF amplifier with using the second oscillation signal and output the heterodyned signal in the first single receiving mode.

An amplifier circuit includes a variable gain amplifier that amplifies and outputs a signal from an output port, a controller operable to change an gain of the variable gain amplifier, a mixer that mixes the signal output from the output port of the variable gain amplifier with a local oscillating signal to heterodyne the signal and outputs the heterodyned signal, a filter that outputs a signal component having a predetermined frequency out of the signal output from the mixer, and a detector that detects a power level based on power of the signal output from the filter. The controller is operable to change the gain according to the first power level such that a quality level representing quality of the signal output from the filter becomes a target quality level immediately after the gain is changed. The amplifier circuit can have small power consumption.
摘要:
In an autonomous vehicle, position of a planar obstacle such as a wall or a fence having apertures is determined. A horizontal plane is scanned with a laser range tinder so as to acquire positional coordinates of a plurality of scanning points. An element vector is formed with each two scanning points so that one acquired former is used as a start point and the other acquired later as an end point of the vector. A plurality of continuous element vectors which satisfy predetermined conditions is selected among the element vectors, and a scanning segment vector is formed by composition of the selected element vectors. When a length of the scanning segment vector is equal to or longer than a predetermined length, it is possible to recognize that a planar obstacle exists along the scanning segment vector.
