Title: Correction device for delay detector
Inventor: OIKAWA HIROKI
IPC: H04L27/227
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in reception sensitivity by detecting a frequency shift of a reception signal, using a discrimination axis correction means so as to stop correction of discrimination axis and to prevent malfunction thereby suppressing adverse effect on received data with a frequency shift. SOLUTION: A symbol phase error monitor means 21 detects an error of a differential result obtained by a delay detection wave with respect to an ideal differential result. Then a discrimination axis correction means 22 estimates a phase error of a succeeding symbol based on a symbol phase error of the detected result to correct a discrimination axis of a data discrimination means 20. Thus, the error in the discrimination result is reduced and the reception sensitivity is improved. When a frequency shift is in existence in a reception signal, a frequency shift detection means 24 detects the frequency shift, a stop means 25 stops the discrimination axis correction of the discrimination axis correction means 22 to prevent malfunction. Thus, adverse effect on received data with a frequency shift is suppressed and the deterioration in the reception sensitivity is prevented.

The element 16a forms the two-dimensional image corresponding to disturbing light P3 and reflected light H3 and the element 16b having the same characteristics forms the two-dimensional image corresponding to disturbing light P4 only. A comparator 18 compares the outputs S3 and S4 of the elements 16a and 16b with each other at every picture element at corresponding coordinates and only selects the picture element when the output S3 indicates the presence of a two-dimensional image as the two-dimensional image of the target 1. An angle computing circuit 19 computes the relative position between the measuring section 14 and target 1 based on the output S4.

Abstract: PURPOSE:To toast bread most suitably, by a method wherein an electric current is applied to only a lower heater only during a specific short time, and while the slices of the bread placed on a tray are being heated, the number of the slices and the amount of water contained therein are determined by the rising gradient of temperature in a heating chamber, and the electric current is simultaneously applied to an upper heater and the lower heater by controlling a time when applied to them. CONSTITUTION:First, an electric current is applied to only an lower heater 4 only during a specific short time. while the slices of bread A on a tray 2 are being heated only from below, the temperature in a heating chamber 1, which is detected by a thermal sensor 5, is monitored, and the number of the slices of the bread A and the amount of water contained therein are determined by the rising gradient of the temperature in the chamber 1. The electric current is simultaneously applied to an upper heater 3 and the lower heater 4 by controlling a time at which the electric current is applied according to the magnitude of the number of the slices and the amount of the water decided, and the slices of the bread A are most suitably toasted. The larger the number of the slices of the bread A and the amount of the water contained therein are, the gentler the rising gradient of the temperature in the heating chamber 1, which is detected by the thermal sensor 5, and the number of the slices of the bread A and the amount of the water contained therein are determined by the rising gradient thereof. Since the heating time of the upper and lower heaters 3, 4 is automatically set by the determination, most suitable toast of which the color of the toasted bread is always the same can be obtained.
