Title: Lighting system
Inventor: KANZAKI SATOYUKI
IPC: F21S8/08
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a lighting system that is installed outdoors, mainly on a road or in a park or a square in front of a station, etc. SOLUTION: This lighting system comprises a solar battery 1 converting solar energy into electric energy, a storage battery storing the electric energy, a light emitting part 3 providing night illumination using the stored electric energy, and a control board for controlling the operation of the light emitting part 3, and does not therefore require a commercial power supply, so it eliminates the need for wiring overhead cable or the like and for construction work for burying it and is easy to install. Also, since a control box 4 holding the storage battery and the control board has the function of a bench and does not spoil the view, the lighting system is excellent in viewability, and if a pedestrian takes a rest at the site where the lighting system is installed, he/she can sit on the control box 4.

Title: Crawler type vehicle
Inventor: SUZUKI RYOHEI
IPC: B62D11/22
Filed: 1984-07-31
Abstract: PURPOSE:To reduce frictional turning resistance in time of a pivot turn, by connecting a keeping device by means of a hydraulic cylinder in a crawler type vehicle to an outlet port of a shuttle valve between pipe lines connected to a hydraulic motor rotating a driving wheel via a selector valve. CONSTITUTION:When one side hydraulic motor 11R is driven and the other hydraulic motor 11L is stopped, pressure is produced in an outlet port of a shuttle valve 13R but this pressure is not produced in an outlet port of a shuttle valve 13L to that pressure oil in not fed to a hydraulic cylinder 7R which therefore comes into a state of being contracted. A directional control valve 14R comes to an (a) position, while driving pressure of the hydraulic motor 11R is fed to a chamber at the bottom side of a hydraulic cylinder 7L via the shuttle valve 13R, the directional control valve 14R, and this hydraulic cylinder 14L extends longer. Therefore, the central part of a crawler 6L comes into a state of being grounded and thereby a crawler 6R alone is driven, thus a pivot turn takes place.

Title: Method for scanning characteristic magnetic field in nuclear magnetic resonance image method
Inventor: YAMADA YOSHIFUMI
IPC: G01R33/48
Filed: 1982-09-16
Abstract: PURPOSE:To perform simply and rapidly a concrete scanning of a rod-shaped characteristic magnetic field by synthesizing a static magnetic field H0 and a magnetic field causing by a coil group to generate a characteristic magnetic field DELTAHs, and superimposing and varying a scanning magnetic field component of the magnetic field due to the coil group governing the magnetic field strength variation of the field DELTAHs. CONSTITUTION:If a scanning parallel filament coil generating almost uniform magnetic field is provided and the ampere number NsIs is set, the magnetic field of the scanning coil turns to the (x) axis direction and has almost no magnetic field component in the (x) axis direction. If the scanning magnetic field Hs is impressed superimoposingly in the (x) direction, the zero magnetic field point moves to a position Xs on the (x) axis, and the rod-shaped characteristic magnetic field obtained at the time is shown by an equation I . The center of the rod-shaped characteristic magnetic field DELTAHs moves to the position Xs, and it is found that the moved amount, namely the scanned amount can be varied in proportion to the current Is of the scanning magnetic field generating coil from the equation I . Also with respect to the (y) axis direction, if a uniform magnetic field for (y) direction scanning is impressd superimposingly by a (y)-direction scanning coil, the scanning can be performed extremely simply and easily.

Title: Line thermal printer
Inventor: ASAI YOSHINORI
IPC: B41J25/316
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To calmly open a cover member supporting a thermal head without making an operator feel anxiety about safety. SOLUTION: A damper 22 is set which urges by means of a coveropening spring 18 a cover member 6 supporting a thermal head 7 to separate the member by a predetermined angle from a platen 4, and applies a smaller resistance force than an urging force of the opening spring 18 from a middle stage to a final stage of the separation of the cover member 6 from the platen 4. When a stop lever 13 is detached from the cover member 6, the cover member 6 is separated together with the thermal head 7 from the platen 4 because of the urging force of the opening spring 18. However, the resistance force of the damper 22 acts to the cover member 6 from the middle stage to the final stage of the separation, whereby an open speed of the cover member 6 is attenuated. Accordingly the cover member 6 can be opened calmly without causing an operator anxiety about safety.

The oxygen detector thus constructed is inserted into the passage of gases to be measured to introduce the reference gases (e.g., air) into the electrolyte 11 from the tube 14. Then, the temperature T of the electrolyte 11 and the electromotive force between the electrodes 12 and 13 are measured such that the former is detected by means of a temperature measuring element 15. Then, Equation I is used to deduce the partial pressure Po 2  of oxygen in the gases. Incidentally, by injecting the calibration gases from the outlet 16 through a conduit 17, the calibration can be accomplished while leaving the detector attached to the gas passage.
