Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To secure a power for to interchanging and supply reserves, by using object knowledge expression or the like due to an expart system for determining cascade interchange when the capacity of the adjacent power supply of a section to be interchanged is insufficient. SOLUTION: When an accident occurs at a point F on the feeder of a power supply G1 , a total amount of lead L1 of a section to be interchanged being detected by performing search in all directions from one node in the section to be interchanged is compared with sum ΣRG2 of the supply reserves of the group of adjacent power supples G2 . As a result, when cascade interchange is required, the adjacent power supply G2 is set to a cascade target power supply. Then, a power supply that is adjacent to the power supply G2 and has large supply reserves is set to a cascade power supply G3 , the sum of the sum ΣRG2 of the supply reserves of the group of adjacent power supplys G2 and supply reserves RG3 of the cascade power supply G3 is compared with the total amount of load L1 of the section to be interchanged.  As a result, when cascade interchange can be made, switching means CB, CB1 , and CB2 for coordinating the adjacent power supplies G1 -G3 and the switching state of a switching means S1 on the feeder are determined.

Title: Method of adjusting driver, wrench main body and joint
Inventor: BURAIAN MAN
IPC: B21D39/00
Filed: 1994-05-02
Abstract: PURPOSE: To provide a driver for jointing capable of indicating properly torque application. CONSTITUTION: Axially extending lobes extend radially from an internally threaded nut 20 and form axial troughs that receive a respective axial cone mounted in the socket 18 of a driver 12, the cones being rotatably driven against the lobes to apply a threading torque to the nut. At a predetermined torque, an axial outer radial end portion of the material forming the lobe is plastically deformed, but not sheared off, thereby allowing the socket to rotate and the cones 56 to advance against the next lobe. The deformed lobe indicates to the user that the nut was properly torqued and the deformed material does not shear off thereby indicating that the nut had not been tampered with. To permit relaxation, auxiliary torquing may be done later.

Title: Device for measuring surface roughness
Inventor: KURITA MASAKATSU
IPC: G01B11/30
Filed: 1981-06-18
Abstract: PURPOSE:To obtain the measuring device characterized with a simple constitution, high sensitivity, and a short processing time, by detecting the reflected diffraction image of coherent light which is irradiated on the surface to be measured by a space filter receiver. CONSTITUTION:The coherent light 6 from a laser light source 1 is reflected by the surface to be measured 2. A speckle pattern is formed on the space filter receiver 3 by the reflected light 7. As the rough surface 2 moves, the pattern on the space filter receiver 3 also moves, and a sine wave output is obtained from a differential amplifier 4. In the case of the smooth routh surface which has about a half wavelength of the laser light, the difference in a light path having the half wavelength or more cannot be obtained, and parfect interference is not  obtained. Therefore the space frequency of the speckle is low. In the case of  severe rough surface, the space frequency becomes high conversely. When the  band pass filtering is performed by the space filter, a voltage value can be  detected as the function of the roughness by a wave high value detector 5.

Title: Gaas/si multilayer and gaas growth method
Inventor: ONOZAWA SACHIKO
IPC: H01L21/84
Filed: 1988-04-19
Abstract: PURPOSE:To reduce stress in a GaAs layer, by providing a GaAs layer which is caused to grow from the exposed area of a silicon substrate other than an insulating film partially formed thereon and has cavities over the insulating film. CONSTITUTION:A GaAs layer 25 is provided which is caused to grow from the exposed area 21b of a silicon substrate 21 other than an insulating film 23 partially formed on the surface of the silicon substrate 21, and which has cavities over the insulating film 23. Therefore, the GaAs layer 25 is contacted to only the exposed area of the silicon (Si) substrate 21 other than the insulating film 23 thereon, so that the contact area between the GaAs layer 25 and the silicon substrate 21 is decreased. As a result, stress in the GaAs layer 25, which is generated due to the difference between a thermal expansion coefficient of the Si and that of the GaAs, is effectively reduced. Further, due to the presence of the cavities 25a, the GaAs layer 25 is not contacted to the insulating film 23, which also promotes the reduction of the stress in the GaAs layer 25.

Filed: 1979-07-25
Abstract: PURPOSE: To enable accurate following-up to large strain, reduce it and transmit the reduced strain to a strain-sensitive section, by appropriately selecting the thickness and material of an insulating board.  
     CONSTITUTION: A leaf of a resistive metal 12 is bonded on an insulating board 11 which is made of silicone rubber or the like and whose material and thickness are appropriately selected. Strain-sensitive sections 13 are then made by photoetching on the board. After that, the board is cut into several elements. Lead wires 14 are soldered on the elements. A cover 15 made of an insulating material is placed in tight contact with each element, thereby completing a strain gauge element for large  strain. The board 11 of the strain gauge is bonded on the measuring surface. The  change in the strain of the resistive metal 12, which is deformed depending on the  strain of the surface, is picked out in the form of the variation in the resistance. If a  material is selected for the board 11 and its thickness is made large, the strain of  the measured object is attenuated by about 10% and then transmitted to the strain- sensitive section 13 so that an accurate measured value is provided.

Title: Segment and circular arc recognizing system
Inventor: YAMANISHI ASAO
IPC: G06K9/62
Filed: 1986-04-25
Abstract: PURPOSE:To recognize stable segments and circular arcs by recalculating an area between the row of short vectors and an approximate circular arc on each short vector and evaluating the area as an error. CONSTITUTION:Existence of a short vector vi is checked, and when the vector vi exists, an approximate circular arc Ci for short vectors v1-vi is obtained. Then, the approximate error of the approximate circular arc Ci for obtained short vectors v1-vi is found. Here, the approximate error epsiloni is defined as the sum of areas S1-Si and areas enclosed by the circular arc Ci, vectors v1-vi and normals 2-5. The obtained error epsiloni is compared with a predetermined allowable error epsilon0. If the error epsiloni is smaller than the error epsilon0, above-mentioned process is repeated. When the vector vi does not exist or epsiloni>epsilon0 is detected, the short vector is judged as a circular arc or a segment according to the result of comparison of the radius of the approximate circular arc and a reference value.

IPC: B41J7/34
Filed: 1984-05-11
Abstract: PURPOSE:To enable the attainment of low cost, low noise, excellent alignment, high-speed printing, miniaturization and reduced power consumption, by stopping a type at the moment of printing by a driving member and a follower member engaging therewith. CONSTITUTION:Since a driving member 1 connected directly to a motor 5 rotates in the direction A, the lead portion (a) of the member contacts with the sliding face (d) of a follower member 2. With further rotation of the member 1, said portion (a) and face (d) move slidably to each other, and thereby the follower member 2 is rotated in the direction B. When the sliding motions of the lead portion (a) and the sliding face (d) are ended, the follower member 2 has stopped in a state in which a subsequent type is found at a printing position. While the driving member 1 continuous rotating, the follower member 2 is at a standstill since the straight portion (b) of the member 1 engages with the supporting faces (f) of the member 2 after said sliding motions, and in the meantime, a printing magnet is excited to protrude a hammer and to perform printing by a type 3 of a type drum 9.
