Title: Information display method
Inventor: NAKAJIMA SANTAROU
IPC: E01F9/00
Filed: 1996-08-21
Abstract: PROBLEM TO BE SOLVED: To display road information even at a place, where an effective space is not obtained due to restriction boundary of building, by mutually arraying a plurality of line display boards at regular intervals along the progressive direction of a road respectively and displaying specified road information by these all line display boards. SOLUTION: Line display boards 1, in which light-emitting sections using LEDs, etc., as light sources are arrayed in a dot matrix shape, are disposed to the ceiling wall of a tunnel T at regular intervals along the depth direction of the tunnel T respectively. Consequently, when a car C is placed at a spot in front of the line display boards 1 such as a position in front of 60m, each line display board 1 is viewed as if they were connected continuously in the vertical direction by the relative positional relationship of the angle of a visual field of a driver and the depth, and viewed as the display screen of one plane as a whole. Accordingly, road information can be indicated even at a place, where an effective space is not acquired by the restriction boundary of building of the tunnel, etc., having no emergency parking lane.

Abstract: PURPOSE:To enhance the safety of a nuclear reactor and the reliability of a reactor shutdown apparatus by automatically changing over the exciting system due to a main coil to the exciting system due to a sub-coil when the former system gets out of order. CONSTITUTION:When a main exciting cable 18a becomes a disconnection state or a contact inferior state, it is detected that an exciting current is lost or becomes unstable by the usual voltage of a power supply on the basis of the input signal from an input circuit 22a to generate an alarm to the effect that the main exciting cable 18a gets out of order. Simultaneously with the generation of the alarm, the input circuit 22a and an output circuit 24a are cut off and the input circuit 22a is changed over to an input circuit 22b and the output circuit 24a is changed over to an output circuit 24b. Therefore, when any trouble is generated in a main DC power supply apparatus 19a energizing a main coil 14a and the main exciting cable 18a, the auxiliary DC power supply apparatus 19b, auxiliary exciting cable 18b and sub-coil 14b of a backup system are immediately set to an operative state and an electromagnet 3 is not de-energized and, therefore, the unnecessary scrum of a nuclear reactor is not generated.

A fractional flow of the unreacted material in the ether producing device is sent to a distillation tower 122 where the top fraction of the tower is circulated again as the hydrocarbon source flow to the reactor 104. The bottom flow of the distillation tower 122 is sent to separator 126' where n-butane is separated from butene-2. The butene-2 is again circulated to the reactor 104. The n-butane is sent to an isomerization device to isomerize into isobutane, which is used as the source material for the reactor 104.

Filed: 1993-09-06
Abstract: PURPOSE:To obtain a p-n junction photocell which is connected to an optical fiber and has a microminiature light reception part where incident light is absorbed within the depletion layer of p-n junction. CONSTITUTION:A projecting part and a recessed part 3 are formed on the surface of an n-type epitaxial layer 1b with a medium resistance on a low- resistance substrate 1a and then boron is subjected to impurity diffusion from the surface of the projecting and recessed surface to form a p-type layer 4. At this time, a p-n junction 6 is formed between the n-type epitaxial layer 1b and the p-type layer 4, a depletion layer 7 spreads to both sides of the side of the n-type epitaxial layer 1b and the side of the p-type layer 4 and an n-type region 5 which is not a depletion layer 7 remains within the projecting part 2a which becomes a light reception part. Therefore, when light enters from an optical fiber 30 with a core diameter which is equal to the diameter of the projection part 2, most of the incident light advances along the p-n junction part 6, is adsorbed by the depletion layer 7 and the remaining n-type region 5, generates a pair of electron and positive hole and hence the electron electrifies an electrode 10 negatively and the positive hole electrifies an electrode 11 positively.
