Title: Response diagnostic method of air-fuel ratio sensor of internal combustion engine
Inventor: FUKUCHI EISAKU
IPC: G01N27/409
Filed: 1995-03-17
Abstract: PURPOSE: To obtain a response diagnostic method in which a degradation index is separated into a rise part and a fall part and whose diagnostic accuracy is enhanced by a method wherein the output waveform and the reference waveform of an O2 sensor are found, a rise integrated value and a fall integrated value are found and the degradation of the O2 sensor is judged on the basis of the difference between both. CONSTITUTION: A flow-rate detection means 104 is attached to an intake system for an internal combustion engine, and an O2 sensor 102 as an air-fuel ratio sensor is attached to an exhaust system. Then, in order to judge the degradation of the O2 sensor 105, an output waveform and a reference waveform are found, and integrated values which are decided by their rise waveforms or their fall waveforms are found respectively. The difference between the two integrated values is found, and the degradation of the O2 sensor 105 is judged.  Then the rise integrated value and the fall integrated value of the O2 sensor are found in 2 this manner, it is possible to separate the degradation into a rise part and a fall part, and the diagnostic accuracy of a response diagnostic method can be enhanced when the area of a part which is not related directly with the rise part and the fall part is not included in a rise-part area and a fall-part area.

Title: X-ray generator
Inventor: OKADA IKUO
IPC: H05G2/00
Filed: 1985-03-25
Abstract: PURPOSE:To stably and reliably control switching of the movable valve of a high-speed switching gas valve with simple structure and minimize the variation in switching operation by using electromagnetic force to switch the movable valve. CONSTITUTION:A plasma production chamber 10 is usually maintained at a proper vacuum by means of a vacuum pump 12. When gas 26 is fed into an X-ray generator by the operation of a high-speed switching gas valve 16, plasma is produced in a plasma production regions 13 located between a high voltage electrode 3 and a low voltage electrode 5. As the result, X-rays 15 are produced which are then led outside the generator through an X-ray discharge window 6. Electromagnetic force is used to move the movable valve 22 of the high-speed switching gas valve 16 upward during gas feeding thereby making the plasma production chamber 10 continuous with a gas chamber 25. Then, the valve 22 is moved back to its original position by its own weight thereby breaking the connection between the two chambers. Due to the above simple structure, the weight of the valve 22 can be reduced and the valve 22 can be driven by reduced force.

Title: Turn-back mirror of laser beam scanning optical system
Inventor: KYOGOKU TETSUO
IPC: G02B5/08
Filed: 1988-03-12
Abstract: PURPOSE:To easily and inexpensively correct the nonuniformity in the exposure on a photosensitive surface by forming an increase reflecting film which is gradually increased in film thickness from off-the-optical axis to on-the-optical axis to the reflecting face of the turn-back mirror. CONSTITUTION:The increase reflecting films 7a, 8a are provided in common used as protective films to the turn-back mirrors 7, 8. The increase reflecting film 8a of said films is so formed that the film thickness thereof increases gradually from the off-the-optical axis to the on-the-optical axis. A laser beam is, therefore, changed in the reflectivity by the thickness of the film 8a so that the reflectivity is small on the optical axis and is large off the optical axis. As a result, the reflectivity is small and the exposure decreases on the optical axis where the scanning speed is low. The reflectivity is large and the exposure increases off the optical axis where the scanning speed is high. The nonuniformity in the exposure on the photosensitive surface is thereby easily and inexpensively corrected even if a costly ftheta lens is not used.

Title: Channel clock forming device, reproducing device and recording and reproducing device for disk shaped recording medium
Inventor: MUTO TAKAYASU
IPC: G11B20/10
Filed: 1993-03-18
Abstract: PURPOSE:To eliminate the case in which a VCO is driven by incorrect phase error detection data even though a defect is generated in a magneto-optical disk and to continuously output a correct phase channel clock which is being outputted. CONSTITUTION:The recording and reproducing device consists of a phase locked loop which drives a VCO 35 that outputs a channel clock in accordance with a channel clock phase error (phase error detection data) against the detection data of servo patterns recorded with prescribed intervals on a magneto-optical disk 1. When the servo patterns are not detected due to the defect on the disk 1, a zero data output circuit 31 outputs zero data to the VCO 35 in place of the phase error detection data indicating that a phase error is zero.

Title: Panel file
Inventor: AASAA TEI SUPIIZU
IPC: B42F17/18
Filed: 1979-05-14
Abstract: A panel file, for the storage of flat, flexible data elements, consists of plural, vertically overlapping pockets, the entrances of which are formed by a plurality of vertically spaced, horizontally extending strips (26) of resilient material. The strips are arranged so as to have an upper edge which overlaps the lower portion of the next upwardly adjacent strip. The strips are fastened together at their lateral margins (179).The lower portions of the pockets are formed by a support sheet which is attached to the panel on the surface opposite the pocket entrances. The support sheet is cut so as to have a column of inverted "V"-shaped straps (42), each having a vertex (192) which is attached to the back of a strip. The strips have an upwardly concave bottom edge (180) with a central vertex at the point (128) where the support sheet strap is attached to the next downwardly adjacent strip. Thus, the attachment point between a strip and a strap is located in an area of the panel having the thickness of only one strip, which area is below the lower edge of an upwardly adjacent strip and above the upper edge of a downwardly adjacent strip. Thus constructed, the overlapping pockets are individually openable, and do not become increasingly constrictive as the panel is filled. The panel thus constructed also has a minimum number of overlapping layers at any point.
