IPC: G02F1/1333
Filed: 1995-06-06
Abstract: PURPOSE: To make it possible to control the ruggedness required for light scattering to a desired size in the unit of light wavelengths by forming the above device of a transparent insulating substrate, granular materials and projecting semiconductors, thereby allowing the co-presence with the process for fine working to form a TFT matrix. CONSTITUTION: A transparent conductive film 2 consisting of the oxide of at least one metal selected from In, Sn and Zn is first formed on the transparent insulating substrate 1. The surface of this transparent conductive film is then exposed to plasma contg. at least hydrogen, by which the surface is reduced and the granular materials 3 contg. at least any one metal are precipitated. The projecting semiconductors 4 are then grown with the granular materials 3 as nuclei, by which a light scattering plate having the ruggedness is obtd. The ruggedness consisting of such projecting semiconductors 4 does not cause such problem as impartation of damage to the substrate or difficulty in the control of the rugged sizes, any more, unlike the case where mechanical working is executed by using a polishing agent.  The possibility that the number of stages is increased and an increase of the cost is resulted is eliminated as compared with the case where a lithography technique is used.

Title: Traffic signal control system
Inventor: OGURA MASAMI
IPC: B60W30/00
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To permit the driver of a leading vehicle at the time of rank travel to enter a crossing with ease without being conscious of the remaining time of green signal display. SOLUTION: When a rank comes before a crossing, a leading vehicle transmits a present position, a rank length and the route (straight, turn right on left) in the crossing to a communication unit 8 installed in a shoulder of a road. Information and the remaining time of green signal display are transmitted to a center 7. The center 7 obtains necessary time that the last vehicle passes through the crossing and judges whether the last vehicle can cross the crossing from above time and the remaining time of green signal display. When it judges that the vehicle cannot pass, the prolonging time of green signal display is operated and it is transmitted to a signal controller 6. The signal controller 6 adds the prolonging time to the remaining time of green signal display and the display time of a green signal is prolonged until the last vehicle finishes passing the crossing.

Title: Heat accumulating device using metal hydride
Inventor: SAKAI TAKASHI
IPC: F28D15/02
Filed: 1981-09-07
Abstract: PURPOSE:To prevent a heat pipe from being broken and consequently stabilize the operation of the heat pipe by a structure wherein one end of the heat pipe, the other end of which is connected to a compartment, which is provided within a metal hydride vessel and packed with latent heat type heat accumulating material. CONSTITUTION:The compartment 5, which contains no metal hydride therewithin and is packed with latent heat type heat accumulating material 6, is provided within the metal hydride vessel 1 and the heat exchanger 3 and the compartment 5 are connected with each other by means of the heat pipe 2. In this case, inorganic salt having a transition point of about 70-200 deg.C such as magnesium nitrate hexahydrate or the like is employed as latent heat type heat accumulating material 6. Owing to the structure as described above, even when metal is hydrogenized and abrupt heat release occurs, the heat is absorbed in the form of sensible heat until the transition point of the latent heat type heat accumulating  material is reached and the heat over said transition point is absorbed in the  form of latent heat. Accordingly, the temperature, at which the breakage of the  heat pipe occurs, can not be attained and the stable operation of the heat pipe  can be resulted.

Abstract: PROBLEM TO BE SOLVED: To adjust a call tone volume at the arrival of an incoming call by detecting a lightness around the telephone set and a level of a voice and judging the possibility of use of the telephone set by the user depending on a temporal change in the detection output. SOLUTION: A sound pressure detection circuit 2 and a contrast detection circuit 3 detect a state from a sound pressure sensor and light sensors A, B for a prescribed period. When a telephone line circuit 1 detects the arrival of an incoming call from a telephone line, the telephone line circuit 1 sends an incoming call signal to a control circuit 4 and the control circuit 4 checks a state change of the state of the sound pressure sensor and the light sensors A, B from the sound pressure detection circuit 2 and the contrast detection circuit 3 for a prescribed number of times.  The control circuit 4 uses the sound pressure sensor to sense a sound volume around the telephone set, and when the low sound pressure level detected by the sound pressure detection circuit 2 for a prescribed time continues and the lightness changes rapidly and the dark contrast continues for a prescribed time, it is estimated that the user is asleep. Then the sound volume of the call tone is adjusted so as not disturbing the sleep of the user.
