Title: Valve gear of cylindrically aligned cylinder
Inventor: KITAGUCHI HIROMASA
IPC: F01L1/04
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To simplify the structure of a valve gear and to reduce noise generation by meshing the same number of crossed helical gear pairs with cams as the number of cylinders around the crossed helical gear pairs fixed to an output shaft and opening and closing a valve through a rocker arm according to movement generated by a cam portion. SOLUTION: When an engine is started and an output shaft 6 revolves, crossed helical gear pairs with a cam 2 which mesh with crossed helical gear pairs 1 fixed to the output shaft 6 are reduced to 1/2 rotation and rotate together with a cam portion 3. When this happens, a rocker arm 4 which is contacting the cam portion 3 rotates around a crosspiece support and a valve 5 opens and closes through this rocker arm 4. In this way, because the structure such that the crossed helical gear pairs 1 rotate together with the output shaft 6, reduction gears are no longer necessary and the structure is able to be simplified because the crossed helical gear pairs 1, 2 enable the speed to easily be reduced to 1/2. Further, quiet operation is made possible since the torsion of the teeth of the crossed helical gear pairs 1, 2 can be made larger.

Title: Noise reduction device
Inventor: MISHIMA HIDETOSHI
IPC: G11B20/02
Filed: 1988-08-05
Abstract: PURPOSE:To prevent deterioration in the transient characteristic from being called for even if the noise component is reduced by extracting a signal component without any line correlation of each input signal with a correlation device comprising a nonlinear circuit and subtracting the extracted signal from the input signal. CONSTITUTION:A signal retarding an input signal by a 2-horizontal scanning period (2H) with 1H delay devices 5, 6 to eliminate a low frequency component, a signal whose low frequency component with 1H delay by a 1H delay device 5, a signal whose low frequency component is eliminated without any delay are generated and they are inputted to a correlation device 7 comprising a nonlinear circuit. Then an output of the correlation device 7 is subject to amplitude limit by a limiter 8 and the result is subtracted from the signal whose low frequency component is eliminated with 1H delay. The correlation device 7 consisting of the nonlinear circuit does not output the correlation signal of the transient part of the input signal. Thus, even if the noise component is reduced, the vertical transient characteristic is not deteriorated.

Filed: 1984-09-21
Abstract: PURPOSE:To display exactly a position of a vehicle by storing in advance a bearing data by providing plural specified points on a road map of a picture, and discriminating the magnetization of a car body from a bearing difference between a measured bearing data and the specified point, when the vehicle has passed through the specified point. CONSTITUTION:Data from a distance sensor for measuring a running distance, and a bearing sensor for detecting X and Y components of an earth magnetism are inputted to a vehicle position operating means, and the present position is displayed on a display device. Also, specified points are determined in advance in a road map, and an exact bearing data of each specified point is stored in advance. In this state, when a vehicle passes through at least two or more specified points of each different bearing, a bearing difference between a measured bearing data and a specified point bearing data is discriminated. Based on this bearing difference, whether the vehicle has been magnetized or not is detected, and an error of the bearing due to magnetization is corrected. Accordingly, since the magnetization of the vehicle is corrected in the course of running, a vehicle position and a locus can be displayed exactly on a running display device.
