Title: Checking system for interference between robot and work
Inventor: OZAWA KUNIAKI
IPC: G06F19/00
Filed: 1984-11-26
Abstract: PURPOSE:To check the interference between a robot and its work at a high speed by approximating the robot with the center segment and the thickness and the surface of the work with a plane to obtain the shortest distance between said segment and plane and comparing the shortest distance with the prescribed threshold value. CONSTITUTION:A robot teaching system comprises an input device 11 which indicates the environments and working commands of the robot, a joint angle arithmetic unit 12 which calculates the angles of each joint of the robot, a memory 13 for those joint angles, a coordinate converting arithmetic unit 14 which displays the 3-dimensional posture of the robot into a 2-dimensional screen, a display device 15 and an interference detecting arithmetic unit 16 which detects the interference of the robot based on the time series data. Then the robot is approximated with the center segment and thickness. At the same time, the surface of a work is approximated with a plane. Furthermore the shortest distance is obtained between the segment showing the robot and said plane. When this distance is shorter than the threshold value obtained in consideration of said thickness, the interference is decided between the robot and the work. This can prevent the breakage of the work.

Title: Communication cable
Inventor: KIYANDAIDO JIYON AROOYO
IPC: H01B7/282
Filed: 1989-09-26
Abstract: PURPOSE: To reduce stresses which optical fibers receive when a medium is longitudinally coupled to an armoring system, so as to effectively stop water form moving radially inward by placing a water blocking member in such a way that a cavity is intentionally formed in a core tube. CONSTITUTION: A communication cable has an axis 21 and includes a core 22. A water blocking member 26 is tubular, is placed adjacent to a core tube 28, takes the form of, e.g. a tape 30, and is hydrophilic; i.e., it has very strong affinity to water since it readily absorbs water. Non-bonding of a transmission medium to an armoring system is effected by aligning a water blocking means in the core tube and other elements so that an intended cavity 40 forms in the core. Therefore, stresses which optical fibers receive when the medium is longitudinally coupled to the armoring system can be reduced, and water can be effectively stopped from moving radially inward.

Abstract: PURPOSE:To prevent a motor from being overloaded by a method wherein a mud- gathering plate that is rotatively provided to the periphery of an inlet device equipped with inlet cutters is put in reverse rotation when displacement in rotation angle of the mud-gathering plate exceeds a set value that is set beforehand. CONSTITUTION:Inlet cutters 5b are rotatively provided to the lower part of a vertical screw conveyor 2, and thereby an inlet device 5 is constructed. A mud-gathering plate 11, approximately in semicircular shape, is provided to the periphery of the inlet cutters 5b. Auxiliary cutters 11a are provided to the inner circumference of the mud- gathering plate 11. The mud-gathering plate 11 is placed round a casing 4, being supported with a bearing 12, and is driven by operation of a motor 15. A rotation angle sensor 15B is provided to the output shaft of the motor 15. In the case where alien substances such as stones and rocks are caught by the inlet cutters 5b while the inlet device 5 is in operation and the inlet cutters are brought into contact with the auxiliary cutters 11a placed behind, causing the motor 15 to be overloaded, signals indicating displacement in rotation detected by the rotation angle sensor 15B are compared with a set value by a controller 30. In the case where the detected value exceeds the set value, the motor 15 is driven in reverse rotation, and thereby the stones and the rocks are released and fallen.

Filed: 1991-09-27
Abstract: PURPOSE:To finish the growth of an epitaxial layer at a time, to reduce a manufacturing cost and to decrease a thickness variation by forming a gate region and source region through selectively introducing a second conductivity- type impurity into a low-concentration first conductivity-type epitaxial layer and thereafter introducing a first conductivity-type impurity all over the surface. CONSTITUTION:N<->-type epitaxial layer 2a is formed on the surface of arsenic- doped <+>-type silicon substrate l. Then, boron is selectively implanted so that a boron injection layer 3alpha is formed. Subsequently, indentation diffusion is conducted so that a boron injection layer 3beta is formed. After that, phosphorus is implanted all over the surface and heat treatment is conducted. The upper part of the baron injection layer 3a is reversed to N<+>-type to become a gate region 3a and simultaneously a part ranging from the surface to a certain degree of depth out of the N<->-type epitaxial layer 2a becomes a source region 4a of N<+>-type. The growth of the epitaxial layer conducted twice heretofore can be finished only once. Also, the variation of thickness and that of electric characteristics can be decreased by an ion implantation method.

Abstract: PURPOSE:To reduce the data transmission cost and a memory capacity by comparing block and each adjacent block, coding the relation between adjacent blocks for each block depending on the quantity of the difference relating to the level of the picture element and coding each block in a plane or in a block based on the result.

One still picture G is divided into plural blocks (g) in m-rows laterally and in n-columns longitudinally. When a difference relating to a level of the picture element between adjacent blocks is small, the block is excluded from an object of in-block coding and the data in each block is compressed up to 2 bits. Thus, the transmission time and transmission cost of a still picture transmitter are reduced and the real time performance is improved, the memory capacity and the cost of a picture filling device are reduced.

Abstract: PURPOSE:To shorten the data length of a synchronizing signal by obtaining a synchronizing output signal on condition that synchronizing signals which arrive successively are coincident in terms of timing and address data are coincident in terms of contents. CONSTITUTION:Address data and synchronizing signal data of a video signal VD inputted to a series-parallel converting circuit 2 are converted 2A and 2B into parallel data S1A and S1B, which are inputted to an address data latch circuit 3 and a synchronizing signal detecting circuit 11.

Abstract: PROBLEM TO BE SOLVED: To make measurable the vacuum degree accurately with high reproducibility by providing discharge terminals in a low pressure chamber contg. an article to be sealed and measuring the discharge start voltage across a discharge gap with a variable voltage applied from external leading terminals. SOLUTION: Discharge terminals 2, 3 having a cantilever structure are formed at one corner on the top surface of a Pyrex glass-made support board 1 in a low pressure package 10 for sealing an angular velocity sensor 10a.
