Title: Combustion condition detector for internal combustion engine
Inventor: INAGAKI HIROSHI
IPC: G01L23/22
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To detect the presence or absence of misfires and knocking through ions near a spark plug with high precision. SOLUTION: A coil T2 applies a voltage to the center electrode of a spark plug P after the spark discharge thereof. When combustion has normally occurred in the cylinder to which the spark plug P is mounted, the voltage is gradually damped by ions generated at the combustion. On the basis of the damping characteristics, a misfire detector circuit 20 detects the presence or absence of misfires. When knocking has been caused at the combustion, the concentration of ions near the spark plug P fluctuates with the result that ionic currents are gradually damped while oscillating. The oscillation of ionic currents results in the oscillation of voltages to be applied to a third resistor R3. On the basis of the oscillation of voltages a knocking detector circuit 30 detects the knocking.

Title: Doppler-type absolute vehicle speed detector
Inventor: MIZUKOSHI MASASHI
IPC: G01S15/60
Filed: 1992-06-26
Abstract: PURPOSE:To improve detection accuracy of absolute vehicle speed by sequentially measuring periods of synthesized Doppler frequency signals and determining the current period if the currently measured period is in its allowable range while if it is not out of the range, the currently measured period is corrected to be determined. CONSTITUTION:Based on transmission wave signals input to a transmitter 1, wares are transmitted against a road surface. A receiver 2 receives waves reflected on the surface among the transmitted waves and outputs a received wave signal indicating the received waves. A Doppler frequency signal synthesizer 3 synthesizes a Doppler frequency signal indicating waves having Doppler frequency from a signal the same as the transmission wave signal input into the transmitter 1 and the received wave signal output from the receiver by utilizing beat of the waves. An absolute vehicle speed determining means 4 sequentially measures periods of the synthesized Doppler frequency signals and determines the current period as a final value from the measured periods to determine the absolute vehicle speed. If the currently measured period is within its allowable range, the period is determined to be the current period, while if it is out of the allowable range, the period is corrected to determine the current period.

Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To prevent toner and carrier from being splashed by providing a device with an inner potential applying means applying inner potential whose polarity is negative or positive with respect to ground potential to a photoreceptor. SOLUTION: This device is provided with a high-voltage power source 61 for applying the potential (inner potential) whose polarity is negative or positive to a base material 11 in the image forming area of the photoreceptor drum 1 and the inner potential applying means 6 including a conductive body 62 for setting the surface potential of the drum 1 to be near the ground potential. By applying the inner potential whose polarity is negative or positive with respect to the ground potential to the photoreceptor 1 by the applying means 6, the image forming area of the surface of the photoreceptor 1 is uniformly electrified to the surface potential whose polarity is positive or negative with respect to the inner potential of the photoreceptor 1. Thus, since the change of the surface potential of the photoreceptor 1 is also reduced when the electrifying action is moved to the image forming area from the non-image forming area, developer is prevented from being unnecessarily attached to the surface of the photoreceptor without executing a complicated control action. Besides, the developer is prevented from being unnecessarily splashed toward peripheral members.

IPC: B60C9/08
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To improve riding comfortableness without sacrificing maneuvering stability by lengthening a tread width direction length in a part corresponding to a center area of the tread by an original carcass line contrast in carcass. SOLUTION: Carcass 2 is made of one sheet or plural sheets of ply of organic fiber cord arranged in a radial direction by straddling a pair of bead cores 1.
