Title: Irradiation direction automatic control mechanism of automobile headlight
Inventor: DOBASHI MASAYUKI
IPC: B60Q1/02
Filed: 1994-11-24
Abstract: PURPOSE: To prevent bad condition from being generated due to linkage by improving an automatic control mechanism which makes headlights move in inclination right and left in linkage with the steering of the dirigible device of an automobile (for example, at the time of vehicle shed entering retreat or at the time of column parking retreat, to prevent a walker and a passing vehicle from being dazzled). CONSTITUTION: A steering angle sensor 9 detects a steering wheel operation state, and a control circuit 21, in linkage with the steering state, moves incliningly right and left lamps 6, 1 to the right and left by controlling the drive unit 4, 2 of the right and left lamps 6, 1. In precedence over the above control functions, headlights are moved in inclination toward an obstacle by means of an advance/retreat deciding means 41 and an obstacle detecting means 42 when an obstacle is detected on the opposite side of a steering direction at the time of retreat.

Title: Optical communication system
Inventor: ASAI TAKAHIRO
IPC: H04J7/00
Filed: 1986-12-05
Abstract: PURPOSE:To eliminate the need for the adjustment of a reception level by using a peak hold circuit so as to hold a peak of a sent reception signal and receiving a data when an output of a reception signal has a prescribed level or over thereby sending plural binary signal data simultaneously through one optical transmission line. CONSTITUTION:To a gate 1 of a transmitter A, n-set of binary signals a1-an are inputted and n-kind of binary signals are converted into the intensity of light of 2<n> gradations and the result is outputted to an optical transmission line B. The optical pulse inputted to a photodetector 6 of a receiver C is converted into a voltage by an amplifier 7 and given to a peak hold circuit 8 and a comparator 9. The peak hold circuit 8 holds the peak of the reception signal. A comparator 10 outputs a data reception start signal OK ('H') when the output voltage of the peak hold circuit 8 is larger than the compared set voltage VSH. Thus, the comparator 9 compares the data signal voltage with a value of 1/(2<n>-1) division of a reference voltage being the output of the peak hold circuit 8 and the result of comparison is encoded and outputted as data signals C1-Cn.

Abstract: PROBLEM TO BE SOLVED: To provide a technology to easily utilize plural databases that have mutually different data structures. SOLUTION: A portable terminal P designates a retrieval condition based on a global ontology G which is a list of data items that are common to plural databases. An agent A is sent from an agent launcher L to a node S for connection. A contrast table of the ontology G and the structure of each database or data that plays the role of a dictionary is prepared on the node S, and a retrieval condition based on the ontology G is interpreted into a form that coincides with the structure of each database based on the data. The agent A moves with the interpreted retrieval condition to a node that has a database, transfers a retrieved result at each node to the node S and after that, returns to the node S.

Title: Optical disk inspecting device
Inventor: MASUI OSAMU
IPC: G01N21/84
Filed: 1987-11-20
Abstract: PURPOSE:To make the human body safe from laser light and rotary bodies by providing a means which decides whether or not an optical disk is mounted on a turntable and whether or not the optical disk is rotating. CONSTITUTION:A reflection type photosensor 3 detects reflected light from the disk 2 when the disk 2 is mounted on the turntable 1. The loading/unloading deciding means for the disk 2 compares the output signal of the photosensor 3 with a 1st threshold level and judges that the disk 2 is loaded on the turntable 1 when the output signal exceeds the threshold level and unloaded when not. Consequently, when the disk 2 is removed from the turntable 1, laser light for inspection is inhibited from being projected. Further, a rotation deciding means for the disk compares the output signal of the photosensor 3 with a 2nd threshold level and judges that the rotation is stopped when the output signal exceeds the threshold level specific times within a set limit. A safety cover is prohibited from being opened during the rotation.

Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To obtain light-weight optical equipment capable of realizing accurate focusing by largely deforming a reflection mirror without using a direct acting mechanism at a focusing part by elongating and contracting a 1st driving means and moving the focal point of the reflection mirror in accordance with the curvature change of the reflection mirror. SOLUTION: A motor 24 being a 2nd driving means drives to rotate a turntable 22 around a 1st axis. Either side of a piezoelectric element 25 being a 1st driving means is fixed at the end of the reflection mirror 23 and the other side is fixed on the turntable 22. Since the mirror 23 is deformed in a direction A by applying voltage (for instance, applying positive voltage) in a direction where the element 25 is contracted by a power source 29, the focal point of the mirror 23 is moved in a direction C. Since the mirror 23 is deformed in a direction B by applying the voltage (for instance, applying negative voltage) in a direction where the element 25 is elongated, on the contrary, the focal point is moved in a direction D.  The operator of this optical equipment obtains a video in focus by adjusting the voltage applied to the element 25 by an adjuster provided in the power source 29 while viewing the video on a CRT 32.

Title: Pipe jamper device for overhead transmission line and fabrication thereof
Inventor: SARUWATARI KOICHI
IPC: H02G7/20
Filed: 1990-10-31
Abstract: PURPOSE:To adapt easily to the environment by constituting a pipe jamper device for overhead transmission line of an aluminum pipe having roughened surface applied with porous anode oxidized film of 0.3-0.5mum thick. CONSTITUTION:Surface of an aluminum pipe or an aluminum angle is sand blasted with abrasive, e.g. corundum, silicon carbide, silica sand, of #60-300 grain size thus roughening the surface with average roughness of 0.5-5mum and maximum roughness of 5-50mum. Thus roughened surface is then immersed in weak alkaline degreaser or washed with water thus removing the abrasive. It is then subjected to anode oxidization thus forming a porous anode oxidized film of 0.3-5mum thick. Anode oxidization is not limited to DC current. A light beam impinging on the film repeats refraction and random reflection thus lowering the brightness. An aluminum member applied with such surface treatment is employed in the fabrication of a pipe jamper for transmission line. According to the method, a jamper having brightness adaptable to the environment can be fabricated easily.
