Title: Information processor and its peripheral device
Inventor: SAITO ASAO
IPC: G06F1/16
Filed: 1994-09-05
Abstract: PURPOSE: To improve the operability of a keyboard input by forming a peripheral device in a wedge shape with the inclined upper surface so as to make its forward side lower in the peripheral device which is superimposed on the lower part off an information processor to be used. CONSTITUTION: The peripheral device (extension unit 20) is formed in a wedge shape with the inclined upper surface so as to make its forward side lower. The connector of the extension unit 20 is connected to the connector incorporated in the information processor 10 through the connector hole of the information processor 1 and the inclined upper surface of the extension unit 20 is made to abut on the lower part of the information processor 10 and fixed. Then, a leg part 12 provided in the processor 10 is set up and used. Thus, the extension unit 20 is arranged in a wedge-shaped space formed between the information processor 10 and a surface.  Since the extension unit is formed into a wedge shape, the forward side of the processor 10, that is, a keyboard 11 is not made high even if the unit 20 is superimposed on the lower part of the processor 10 so that the operability of the keyboard input is not impaired.

Title: Bus switchgear
Inventor: SHIOMI MINORU
IPC: H02B13/02
Filed: 1988-09-20
Abstract: PURPOSE:To prevent simultaneous disconnection of two buses by providing two bus-tie circuit breakers and interruting fault current through one circuit breaker upon occurrence of trouble in the other circuit breaker. CONSTITUTION:A bus-tie circuit breaker 9 comprises two circuit breakers 91, 92 and when a trouble occurs in the circuit breaker 91 which is in the operating range of a bus B protective relay, interruption commands are fed to a feeder circuit breaker 4 connected with the bus B and the bus-tie circuit breaker 9 so that only the bus B is disconnected from the system by means of the feeder circuit breaker 4 and the other circuit breaker 92 thus preventing simultaneous disconnection of both buses A, B. Upon occurrence of fault in the way of transformers 5 for two bus-tie circuit breakers 5, the fault point appears to be within the protective ranges 7, 8 of the buses A, B but the fault current is bypassed and simultaneous disconnection of the buses A, B is prevented. Consequently, any one of the buses A, B is connected continuously even when fault occurs at the bus-tie section thus enabling continuous operation of the bus.

Title: Radiation monitor
Inventor: FUJITA SHINYA
IPC: G01T1/172
Filed: 1994-09-30
Abstract: PURPOSE: To measure the γ-ray of an objective nuclide by arranging a γ-ray detector and a gate γ-ray detector having same geometric efficiency on the opposite sides of an object and interrupting the counting of g-ray through gating when a g-ray is detected by the gate y-ray detector thereby removing the γ-ray produced from a β plus decay nuclide. CONSTITUTION: A main detector 2 and a gate detector 3 are arranged on the opposite sides of an object 1 in the direction of 180 deg. such that they have same geometric efficiency. γ-ray signals detected by the main detector 2 are counted by a counter 5 through an unsimultaneous counter circuit 4. In this regard, an undesired γ-ray is emitted through β plus decay from the object 1, as well as the 7-ray to be measured, and two γ-rays are emitted simultaneously in the 180 deg. directions. Assuming the detectors 2, 3 have a same geometric efficiency, a γ-ray enters into the detector 3 when a γ-ray enters into the detector 2 due to βdecay. When the detector 3 detects a γ-ray, the unsimultaneous counter circuit 4 interrupts the output from the main detector 2 through gating thus removing the y-ray produced through β plus decay nuclide.

IPC: H04N5/365
Filed: 1988-09-21
Abstract: PURPOSE:To suppress stray lights produced by multipath reflection and obtain a solid state image pickup device excellent in color separation by a method wherein a film whose surface has a reflectance approximately equal to or smaller than the reflectance of a light detecting part is employed as the light shielding film of the image pickup device.

Abstract: PROBLEM TO BE SOLVED: To accurately judge events such as the generation of an accident and traffic congestion by using both of a 1st sensor and a 2nd sensor which is not easily influenced by a change in environments to track the running traces or the like of vehicles on a road. SOLUTION: A 1st signal processor 8 calculates information such as running lanes and relative speeds based on the image data of plural vehicles entering a monitoring area obtained by a 1st sensor.

Then, a tracking means 14 measures the running traces of these vehicles in the monitoring area of the 2nd sensor while allowing the outputs of the 1st and 2nd signal processors 8, 13 to correspond to each other. An event judging part 10 recognizes vehicle stop or the like due to an accident or a failure by detecting the distances of these vehicles from the 2nd sensor 11 or a change point of relative speed data.
