Title: Oxygen concentration detector
Inventor: TAKAMI MASAYUKI
IPC: G01N27/406
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To conduct current detection exactly by suppressing sensor current appropriately in any other range than an oxygen concentration detection range. SOLUTION: An A/F sensor (limiting current type air-fuel ratio sensor) 30 outputs a linear A/F (air-fuel ratio) detection signal in proportion to an oxygen concentration in exhaust gas from an engine 10 according to applied voltage commanded from a microcomputer 20. The microcomputer 20 controls the applied voltage into the A/F sensor 30 so as to limit sensor current to a prescribed value in the area out of air-fuel detection range (out of oxygen concentration detection range). The applied voltage is controlled on a V-I coordinate by prescribed positive characteristics in the air-fuel detection range, and the applied voltage is controlled by characteristics different from the above positive characteristics out of air-fuel ratio detection range.  On the rich side out of the air-fuel ratio detection range, the applied voltage is controlled so as to approach the maximum value (0.9V) of electromotive force of the A/F sensor 30. On the lean side out of the air-fuel ratio detection range, the applied voltage is controlled so as to approach the minimum value (0V) of the electromotive force of the sensor 30.

Title: On-vehicle tv system
Inventor: ITO TOSHIYUKI
IPC: H04N5/44
Filed: 1984-12-20
Abstract: PURPOSE:To get rid of turbulent display at a weak portion of TV wave field strength by prohibiting from writing new image data for a memory in the case of bad receiving condition as well as by powering an image after reading image data which were stored already as a memory. CONSTITUTION:A specific frequency broadcasting signal separates TV signals received through an antenna 1 into a video signal and sound signal. The video signals are converted into video data in turn after sending them to A/D conversion circuit 15 and supposing a switching circuit 16 is under a state of working, its video data for one faceplate are written in a digital-memory 17 in order. Meanwhile a field strength detecting circuit 13 and ghost detecting circuit 14 allow a switching circuit 16 to be On when a broadcasting signal is more than a constant level and similarly allow the same circuit 16 to be Off when the broadcasting signal is less than the constant level. In the case of Off state, no fresh video signals are inputted to the digital-memory 17 and then the video signals which were stored under a previous good state are displayed as stand still videos on a picture tube 8.

Title: Illuminating device
Inventor: UENO TOKIO
IPC: F21V9/40
Filed: 1988-10-24
Abstract: PURPOSE:To vary the amount of light continuously with minimum light quantity loss and have good reproducibility by fixing one of the two bandpass filters perpendicular to the optical axis over the whole surface of light source, allowing the other to be inclined from the optical axis any desired, and thereby taking out only the light in a narrow range of wavelength. CONSTITUTION:Two bandpass filters 3, 4 are installed in front of a light source 1, wherein one is fixed vertically to the optical axis while the other is formed as an interferential filter. This is further provided with a drive means a certain degree inclining from the optical axis. That is, a light of a certain narrow range of wavelength is taken out from a white light source by the use of one 3 of the two bandpass filter bundles 3, 4, and the other 4 shall decrease the permeability in this wavelength range continuously. This enables continuous change in the light amount to allow lamp to be lighted always with a proper voltage, which provides stabilized service and suppression of the light quantity loss to approx. 10%, and adjustment of the light quantity can be obtained only with inclination of one bandpass filter. This permits highly reproducible adjustment with simple mechanism.

Filed: 1992-10-07
Abstract: PURPOSE:To prevent the short-circuit flow along the bottom part of a tundish, improve the heat efficiency in the heating and advantageously achieve the float-up of inclusion in molten steel by utilizing electromagnetic force caused by mutual action between DC current and static magnetic field. CONSTITUTION:A static magnetic field generating device 12 is fitted to the bottom part of the tundish under a heating box 6 and the magnetic field B having the direction orthogonally crossing flowing direction of molten steel in parallel with the bottom surface of the tundish. In the molten steel, by a cathode 7 and an anode 8 generating plasma arc for heating, the DC current having the direction orthogonally crossing the magnetic field B is generated. By this mutual action between the DC current and the static magnetic field, the electromagnetic force F having the reverse direction to the short-circuit flow of the molten steel is generated in the molten steel. By this method, the short-circuit flow along the bottom part of the tundish is prevented, and as the flowing speed on the surface of the molten steel is increased, the heating efficiency by the plasma arc is enhanced.

Abstract: PURPOSE:To dispose a tag always on the outside by providing a control device with a first command for gripping an article on a supply means through a first and a second arms in the normally bent state so as to dispose the article tag on the outside, and a second command for gripping the article by the first and second arms in the reversely bent state at the time of loading being constrained. CONSTITUTION:At the time of gripping an article 5 on a supply means 4 through a first and a second arms 1a, 1b in the normally bent state so as to dispose the tag 5a of the article 5 on the loading outer side, a first command is commanded to the control device 6 of an industrial robot 1 to perform loading onto a loading pallet 3. When this loading is constrained by the operating range of an operating part 1c, both arms 1a, 1b are reversely bent by a second command to perform loading. Loading is thus performed in such a way that the tag 5a of the article 5 is always placed on the outside. The loading work of the article 5 can be thereby performed with the tag 5a placed on the outside without installing a robot of two-way bent shape.
