Title: Exhaust apparatus for outboard motor
Inventor: FUJIMOTO HIROAKI
IPC: F01N13/12
Filed: 1983-07-23
Abstract: PURPOSE:To prevent irregular combustion with a rise in the engine exhaust pressure while accomplishing a muffling in a wide range of frequency by communication of an expansion chamber with a sub exhaust port through an underwater chamber. CONSTITUTION:Exhaust of the engine 12 is discharged through a subexhaust port 29 via an expansion chamber 20 and underwater chambers 24 and 26 from a subexhaust pipe 31 so that the rise in the exhaust pressure in an exhaust path 22 of the engine 12 is checked to prevent possible irregular combustion. The exhaust of the engine 12 passes through the expansion chamber 20 and also through the underwater chambers 24 and 26 to effect a muffling in a wide range of frequency. Thus, the passage of the exhaust of the engine 12 through the subexhaust pipe 31 provides a muffling effect of a resonance type thereby accomplishing muffling in a specific frequency range.

Filed: 1986-06-12
Abstract: PURPOSE:To obtain a compact printer head minimizing a number of component parts, by providing a plurality of drive units each having a wire fixed on one end of a lever at an end thereof and a means pressing the other end of the lever against a longitudinal effect type piezoelectric element. CONSTITUTION:Where a distance from a projection 11a of a lever 11 to a shaft 12 is l1 and a distance from the shaft 12 to the tip end of the lever 11 is l2, a ratio of lever gamma results in l2/l1. On the side of a wire 15, an impact force is l/1 of that on the side of a piezoelectric element, and an amount of displacement is gamma-times that on the side of the piezoelectric element. By this amount of displacement, the wire 15 moves in a direction of an arrow (g) to press a recording medium for recording. After the completion of recording, the wire 15 moves in the reverse direction up to its original position due to the resiliency from the side of a platen (not shown in the figure). In this manner, the wire can be driven by a displacement enlarging mechanism using a extremely simple lever mechanism, thus a compact head minimizing the number of component parts and having a superior assembly workability can be obtained.

Title: Output waveform processing method of braking torque generating device
Inventor: MATSUDA KATSUSHI
IPC: B60T8/58
Filed: 1995-06-01
Abstract: PURPOSE: To enable the useful braking force control without repeating the useless control by detecting the braking torque given from a braking device to wheels, and averaging the braking torque for the prescribed period of time to remove the waveform components. CONSTITUTION: In a drum braking device, the periodic output fluctuation is generated due to the true circularity of a drum and the errors of the fitting concentricity when the drum is turned. Because the periodic output fluctuation is equivalent to one turn of the drum, the period of the output fluctuation is obtained from the output of a wheel speed sensor 20 fitted to each wheel in AS controllers 11,19 for a tractor and a trailer. The half-period of the drum is integrated by the braking force to be outputted from a braking torque sensor, and the obtained value is divided by the half-period of time and averaged to be recognized as the implemented value of the braking force. The waveform components are removed from thus recognized braking force, and the useful braking force control can be realized without repeating the useless control by the waveform components.

Title: Automatic analytic method
Inventor: MABE SUGIO
IPC: G01N21/79
Filed: 1994-06-17
Abstract: PURPOSE:To obtain an automatic analytic method in which the presence of a disturbance in a cuvette can be determined by measuring the variation of absorbance of a reaction liquid in the cuvette with time at each period of a cuvette wheel. CONSTITUTION:Every time when a cuvette 1, dispensed 9-11 with a sample from a sample cup 3 and reagents from reagent containers 5, 7, passes a position A (every period), a lamp 12 projects a white light containing a plurality of wavelengths which are not absorbed by a reaction liquid. The light transmitted through the cuvette 1 is passed through a diffraction grating 13 and received by a photodiode array 14. At the end of 8 periods, a cleaning unit 15 discharges the reaction liquid to clean the cuvette 1 thus ending the measurement of absorbance. Presence of a disturbance in the cuvette 1 is then determined based on the measurement results. A normal cuvette 1 is reused but an abnormal cuvette is affixed with display or printer comment information, for example. The cuvette 1. affixed with comment information is replaced, cleaned again, or not used for next analysis.
