Title: Dynamic speaker
Inventor: IWASAKI MITSUO
IPC: H04R9/06
Filed: 1981-12-21
Abstract: PURPOSE:To improve the nonlinear distortion generated by the deformation or the like of a diaphragm and facilitate winding a voice coil without reguiring a special wire rod, by selecting the voice coil so that the thickness of the voice coil becomes thinner according as going toward the outside of the coil. CONSTITUTION:What is called a flat type conductor is used as a wire rod of a voice coil 4. In this case, the conductor is so selected that the thickness of the coil 4, namely, the length in the direction of an axial line 3a of a coil bobbin 3 becomes shorter according as going toward end parts of the coil bobbin 3. Since the coil 4 is so formed that the thickness of the coil 4 is thinner toward the outside of the coil 4, the current density is low in the center part and is higher toward the outside in the direction of the axial line 3a of the bobbin 3. Consequently, the generation of the distortion due to nonlinearity is avoided approximately. Further, the coil 4 is produced very easily, and the coil 4 is wound closely in parts of adjacent turns.

Title: Air-fuel ratio controller for internal combustion engine
Inventor: SHIBATA NORIO
IPC: F02D41/14
Filed: 1988-08-22
Abstract: PURPOSE:To make an air-fuel ratio controllable to a theoretical air-fuel ratio in a highly accurate manner by changing an air-fuel ratio feedback factor to a different value at the time of exhaust control stoppage when exhaust reflux takes place or when an amount of the exhaust is larger than the specified value. CONSTITUTION:An air-fuel ratio correction factor is calculated on the basis of a signal of an oxygen sensor 43 at a control circuit 51 when an engine driving state is in a feedback area. Here, an integration constant in this air-fuel ratio correction factor or a skip quantity takes a different value according to an exhaust gas recirculation(EGR) area and such other than this EGR area. With this constitution, the air-fuel ratio correction factor at this EGR area is made larger or smaller than the case other than the EGR area. Consequently, even if distribution of exhaust reflex to each cylinder at the EGR area is ununiformity, and that the oxygen sensor 43 is liable to be subject to the influence of a specified cylinder, an air-fuel ratio is controllable to a theoretical air-fuel ratio in a highly accurate manner, whereby exhaust gas can be cleaned up thoroughly.
