Title: Simple noise reduction circuit
Inventor: NEGISHI YOICHI
IPC: H04M1/74
Filed: 1994-05-30
Abstract: PURPOSE:To reduce a noise signal mixed into a speech signal by connecting in parallel a pair of diodes provided with mutually equal characteristic with the polarities reverse to each other and serially connecting this parallel circuit to the signal line of the speech signal. CONSTITUTION:A pair of the diodes 3A and 3B provided with mutually equal characteristic are connected in parallel with the polarities reverse to each other and this parallel circuit is serially connected to the signal line of the speech signal SS so as to take out the speech signal SS from a stage in the rear of the parallel circuit of this signal line. Then, the gain, etc., of an amplifier 2 is set lest the level of the noise signal SN outputted from the amplifier 2 is over the threshold levels of the diodes 3A and 3B. Thereby, the diodes 3A and 3B show high resistance with regard to the noise signal SN and the noise signal SN is not provided to n amplifier 4. Consequently, even when the noise signal SN is incorporated to a sound signal system, the noise signal SN is blocked by the diodes 3A and 3B so as to remove or reduce the noise signal SN.

Title: Torque converter structure
Inventor: TAKEKAWA SHIROU
IPC: F16H45/02
Filed: 1991-05-16
Abstract: PURPOSE:To increase the frequency of bearing fluctuations at the time of a slip lock up as well as to check any jadder vibration being produced by a resonance between a vibration attributal to these bearing fluctuations and a natural vibration by setting the number of damper fitting notches, being formed in a lockup piston of a torque converter, down to a prime. CONSTITUTION:A notch 13b for fitting a torsion damper 14 is formed in a lockup piston 13 being situated in the underside of a converter cover 12 of a torque converter 10 at eleven spots at regular intervals in the circumferential direction. Here since the notch number is a prime, a bearing fluctuation occurs as much as 44 times when the number of wavy crests are four in total, at a time when the lockup piston 13 rotates one time on the converter cover 12. A vibration to be produced at the time of 150 (r.p.m.) in relative rotation due to these bearing fluctuations is not accorded with the natural frequency (normally 15-25Hz) of a power train system, so that any judder vibration will in no case occur.

Title: Wave motion gear device
Inventor: NAITO NOBUHIRO
IPC: F16H1/32
Filed: 1989-06-01
Abstract: PURPOSE:To prevent breaking of a boss part while to transmit an output, even when the boss part is in breaking, by providing the second circular spline and setting its pitch circle in size equal to further concentrical with the other circu lar spline while connecting the second circular spline to a rotary shaft with a number of teeth equal to further concentrical with a flexible spline. CONSTITUTION:When a rotary shaft 9 is rotated, relative rotation, caused by a difference between numbers of teeth, is generated between a flexible spline 3 flexed to elliptic shape and a circular spline 2, and an output shaft 10 generates a rotary speed smaller than that of an input shaft 9. When the flexible spline 3 is rotated, also the second circular spline, meshed with this spline 3, is rotated, but synchronous rotation is generated because an equal number of teeth is provided in both the splines. Thus because an output is transmitted to the output shaft 10 through the flexible spline 3 and the second circular spline 11, a load, applied to a boss part 8, is decreased, while even when the boss part 8 is broke, the output shaft 10 can be rotated the second circular spline 11.

IPC: G01N21/77
Filed: 1994-06-22
Abstract: PURPOSE:To detect the concentration of a specific component in exhaust gas having properties variable with time accurately by eliminating the effect of interference components. CONSTITUTION:Exhaust gas sampled from a sampling line 1 is branched into two branch lines 3a, 3b. Dilution gas is fed from a dilution gas supply 9 only to one branch line 3b and the concentration of a specific component in the exhaust gas flowing through the branch lines 3a, 3b is detected at concentration detecting sections 7a, 7b. Since the exhaust gas having identical properties and sampled simultaneously flows into the concentration detecting sections 7a, 7b while differentiating only the dilution ratio, true concentration of a specific component can be calculated based on the detection results from the concentration detecting sections 7a, 7b while eliminating the effect of interference components.
