IPC: F02D45/00
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To diagnose a degradation state of an air-fuel ratio sensor based on a behavior at the time when an output of the air-fuel ratio sensor is recovered to its original state after prescribed voltage is impressed between electrodes of the air-fuel ratio sensor on a prescribed engine operating condition for prescribed time. SOLUTION: When a degradation diagnosis condition is formed by an operating state detection means, an output of an air-fuel ratio sensor when the output of the air-fuel ratio sensor is not reversed is stored. After voltage is impressed between electrodes of the air fuel ratio sensor by a voltage impressing means, impression of voltage is stopped, the monitoring of the output of the air fuel ratio sensor is started and the measurement of time elapsed after the voltage impression is stopped is started. Whether the output of the air-fuel ratio sensor after voltage impression is stopped is recovered to a stored output before voltage impression or not is decided. When the output is decided to be recovered, required time till the output is recovered after voltage impression is stopped is compared with a threshold value set based on rotational speed and load of an engine.  When required time is decided to be larger than the threshold value, degradation of the air-fuel ratio sensor is diagnosed.

Title: Video standard tape
Inventor: OKITA SHIN
IPC: G11B5/455
Filed: 1979-11-21
Abstract: PURPOSE:To ensure easy and accurate control of height for a rotary magnetic head although the track width may differ with each channel, by using the standard tape which contains the standard signals recorded intermittently on the self-track in the nonsignal section of the adjacent track pulse the recording tracks overlapping partially to each other. CONSTITUTION:The recording is carried out on the self-tracks TRB and TRA in the nonsignal section of the adjacent tracks TRA and TRB each having different track widths T1 and T2 on which an azimuth recording is given for the reference signal via the magnetic heads of different azimuth angles. Thus the self-tracks TRB and TRA in the section where the recording is carried out to the adjacent tracks mentioned above become the nonsignal section each, thus forming the standard tape TP on which an overlap recording is given partially. With use of this tape, a reproduction is performed by the VTR to be controlled, and thus the outputs of channels A and B reproduced through each of the tracks TRA and TRE become maximum. The height of the rotary head is controlled to secure a simultaneous increase/decrease for both outputs, and accordingly the height of the head can be controlled in an easy and accurate way even in case the magnetic tapes of different widths may be used.

Title: Posture-maintaining device of vertical surface treating device
Inventor: KONISHI MICHITOMO
IPC: G12B5/00
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To maintain a suspension device in a constant posture by providing a plurality of gas discharge holes in one surface of a housing and providing a gas scattering prevention body for preventing a gas from being scattered. SOLUTION: When a cleaning device is set between a dust-collecting plate 7 and a discharge electrode and a gas is discharged from each gas discharge hole 3 on one surface of a housing 2 of a posture-maintaining device 1, the posture-maintaining device 1 tries to move in the opposite direction from the discharge of air. Further, the discharged gas hits against the dust-collecting plate 7 that is located opposite to the gas discharge hole 3 and is reflected. Since the gas cannot be scattered easily due to a peripheral frame 6, the reflected gas becomes a force for pressing the posture-maintaining device 1 and tries to move the posture-maintaining device 1. The force obtained by synthesizing the two forces interacts with reaction when brushes 9a and 9b contact the dust-collecting plate 7 and the posture-maintaining device 1 is balanced and maintained in a constant posture.
