Title: Combustion condition detector for internal combustion engine
Inventor: OI YASUHIRO
IPC: F02D41/06
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To detect a fuel property without error when an external load is applied by switching a reference value of engine rotating speed into a lower value when the external load is applied. SOLUTION: It is judged whether a shift position of a shift lever for an automatic transmission is in a neutral (N) range or not (S10). As a result, in the case where the shift position is the N-range, a prescribed speed ENEDWNN is set to a reference rotating speed enedown (S12). In the case where the shift position is a drive(D) range, or a reverse(R) range, a prescribed speed ENEDWND is set (S14). When the prescribed speed ENEDWNN is a reference value for detecting fuel property when the shift position is the N-range and an external load is not applied, and the prescribed speed ENEDWND is a reference value for detecting fuel property when the shift position is the D-range or the R-range and the external load is applied, and there is a relation of ENEDWNN > ENEDWND.  After the prescribed value is set, it is judged whether or not engine rotating speed on the basis of an output signal of a crank angle sensor is a reference rotating speed and less (S16). In the case of YES, combustion stabilizing control processing is carried out serving the fuel property as heavy fuel (S18).

Title: Antenna radiation power measuring apparatus
Inventor: KAWAMOTO HIROSHI
IPC: G01R29/10
Filed: 1989-02-15
Abstract: PURPOSE:To enable direct measurement of power radiated from an antenna by using a highly dielectric body for a matching device to receive a radiation radio wave with an antenna for measurement. CONSTITUTION:A transmission power is radiated into a space with a transmitting antenna 2. Highly dielectric bodies 3-5, an antenna 6 for measurement and a powermeter 7 are mounted on this radiation surface. The power radiated into the space is propagated through the dielectric bodies 3-5 to each the antenna 6. Here, the dielectric bodies 3-5 concentrate the radiation electric field while a matching is made between the antenna and the propagation space. The combination of highly dielectric bodies with different dielectric constants prevents diffusion of radio waves outside a propagation path. In addition, the dielectric constant and the thickness of the dielectric body are changed gradually to make a matching between service frequency and the propagation space. The radiation power received with the antenna 6 is applied to a meter 7 to measure a reception power. Finally, a loss of the propagation path containing the dielectric bodies 3-5 are added up thereby enabling measurement of a transmitted radiation power.

Abstract: PURPOSE:To enable an easy and accurate detection of a center position of a hole, by a method wherein a center position of a hole shown in a processing drawing or the like is operated from outputs of two light-detecting elements. CONSTITUTION:Through the movement of an image 22 in the direction X, two light-detecting elements 5 located on points P2 and P3 are set into ON for a duration of only a time during which it moves between a distance M from a point P4 to a point P5 and a distance N from a point P6 to a point P7. Because the points P2 and P3 are fixed on a screen 4, a distance L is fixed, and thus, if the distances M and N during which the light-detecting element 5 is set into ON are found, a point P1, which is the center of the image 22, can be found through the computation. Or, as noted from the drawing, the light-detecting element 5 can be positioned at two points P2 and P3 in order to find the distances M and N, and the two units are enough for the light-detecting element 5.

Title: Distortion eliminating circuit
Inventor: SAKATA EIZOU
IPC: H03F3/20
Filed: 1982-03-10
Abstract: PURPOSE:To eliminate distortion generated in a signal path and to attain stable circuit operation even if the phase characteristics of a feedback circuit is inverted, by comparing an input signal and an output signal of the signal path including a modulation circuit, detecting only the distortion and feeding it back  through demodulation. CONSTITUTION:The modulation circuit 2 is expressed equivalently with an addition section 10 summing a distortion voltage Vd and a carrier signal voltage Vc to an output of a linear amplifier 9, and the amplifier 9 itself. The input signal is applied to an adder 8 and the modulation circuit 2 via an adder 7. The output signal of the modulation circuit 2 is invertedly amplified at an amplifier 11 and applied to the adder 8. The adder 8 detects the difference between the input and output signals of the modulation circuit 2 and applies it to a filter circuit 12. The output signal of the circuit 12 is applied to the adder 7. As a result, a negative feedback due to the signal of the distortion component only is applied to the circuit 2, allowing to eliminate the distortion in the output signal. Since the value of T(s) of the circuit 12 to the input signal is set to 1 and the value of T(s) to a carrier signal is to 0, the oscillation does not take place even if positive feedback is produced.

Abstract: PURPOSE:To improve the reliability of results by detecting the same physical volume with the help of more than 3 units of detector and calculating an average value when a deviation from an average value does not exceed a limit value or output signals from a detector number less than three, and excluding signals exceeding the limit value in cases other than the former. CONSTITUTION:In Step 1, ''N'' number of detectors and a limit value epsilon1 of deviation are provided. In Step 2, a deviation epsilon1 from an arithmetic average of an output signal X1 from each detector is sought. In Step 3, epsilon1 and epsilon0 are compared. If all epsilon1's are smaller than epsilon0's, an average value is sought in Step 9 and is output as a monitoring signal. If all epsilon1's are larger than epsilon0's, it shall be checked whether N's number less than 3 in Step 4 and if the number is less than 3, Step 9 shall be followed. If the number is more than 3, then a detector where epsilon1 is the maximum shall be extracted in Step 5, and its signal be excluded. Following this step, the remaining signals X left over in Step 7 shall be rearranged and 1 shall be subtracted from N in Step 8 and then Step 2 be followed. Under this constitution, it is possible to enhance the reliability of a monitoring signal.
