Title: Measuring method of aging of low alloy steel castings used for turbine casings
Inventor: EBINA TAKU
IPC: G01M15/00
Filed: 1978-03-13
Abstract: PURPOSE: To investigate and measure the degree of deterioration of materials by the use of test  pieces at the periodical inspection and make possible precise repair work by beforehand mounting  the test pieces of the same material quality as that of the material to the material at the time of  production.  
     CONSTITUTION: The turbine casing is formed by contacting its upper part 1 and lower part 2  in the horizontal joint face 3 position to integerally secure these, subjecting the low alloy steel  casting of the casing to hardening then tempering, followed by construction welding and weld  repair then subjecting the same to stress relieve annealing and finally machining the same. The  test pieces 4 provided to the respective inside circumferential parts of the upper part and lower  part 2 are formed of the low alloy steel casting being the same material as that of the upper part  1 and lower part 2 and their heat treatment is also accomplished under the same conditions.  These are then beforehand installed to the casing at the time of its production. After the casing  has been used for a long time under high temperature, the test pieces 4 are cut off and their  performance changes are investigated. Based on the results of the investigations, the determination of the handling of the casing is accomplished.

Title: Current transformer
Inventor: SHIMA KIYOYA
IPC: H01F38/28
Filed: 1979-03-12
Abstract: PURPOSE:To reduce an exciting electro-motive-force and to finish the second winding work in a short time, by installing a bobbin to a winding core, winding secondary windings having 2 or more turns, and inserting a primary winding into the inside of the core. CONSTITUTION:Divided bobbins 11a and 11b are installed to a winding core 10. Secondary windings 14 are formed by rotating 12 the bobbin 11 from the outside and by winding wire 13. In this method, since there is no cut-portion, the exciting electro-motive-force is small and the wire is not required to be stored. Furthermore, winding speed can be acceleraed, and an inexpensive current transformer can be obtained. For example, the current transformer can be fabricated by installing the secondary windings 14a and 14b at the portions opposite to the metal fitting 15, and inserting a primary winding 16 into an insertion hole 16.

Title: Data bus control system
Inventor: NOGUCHI MASAHIRO
IPC: G06F13/376
Filed: 1990-02-07
Abstract: PURPOSE:To attain the re-execution of only the failed access of the data by performing the re-execution from an interruption processing start address via an answer agent when the access of a request agent is through when a conflict of accesses occurs on a bus between both agents. CONSTITUTION:When a bus conflict occurs, an answer agent 5 detects this conflict via a detection circuit 6 and sends an interruption signal 9 to a control circuit 8. The circuit 8 ends forcibly the access carried out by the agent 5 so open a storage circuit 7 and makes a request agent 4 carry out an access. When this access is over, the information of this end is sent to the agent 4 from the agent 5. Then a return address is obtained by subtracting the fixed value from an address where the interruption processing is started. Thus the agent 5 returns immediately to the return address after the end of the access given from the agent 4. Then only the failed access of the data can be executed again.

Filed: 1979-03-09
Abstract: PURPOSE:To reduce the irregularity of trigger current in a planar thyristor due to its boundary level by forming a diffused layer extended from the surface in a diffused region between a cathode region and a gate region in the thyristor. CONSTITUTION:A p-type layer 4 is diffused on the back surface of an n-type semiconductor substrate 1, and the periphery of the substrate 1 is surrounded by a p-type region 3 and isolated from the other region. A p-type region 5 is diffused on the surface layer of the substrate 1, an n-type cathode region 6 is formed in the region 5, and an aluminum electrode 7 is coated on the region 6. When a gate electrode 8 is mounted partially on the region 5 and an oxide film 2 is coated on the exposed surface as a thyristor structure, an n-type region 9 surrounding the region 6 is formed in the region 5. Since the irregularity of gate trigger current in the thyristor is reduced due to the boundary level in the configuration thus formed, the thyristor can be fabricated with preferable reproducibility.

Title: Aluminum group thin-film wiring
Inventor: OKABAYASHI HIDEKAZU
IPC: H01L21/3205
Filed: 1988-02-08
Abstract: PURPOSE:To lower contact resistance, to facilitate bonding and to improve oxidation resistance by coating the surface and side face of a first aluminum group wiring layer with a second aluminum group wiring layer. CONSTITUTION:The surface and side face of a first aluminum group wiring layer 3 are coated with a second aluminum group wiring layer 4. Consequently, wirings are formed by the aluminum group wiring films 3, 4 of two layers, thus simultaneously satisfying a plurality of requirements as a whole by providing each layer 3, 4 with different characteristics. The wirings at a level capable of permitting both characteristics can be shaped by combining a film having large crystal grain size and high electromigration resistance and a film having small grain size and high stress migration resistance. Wiring resistance is lowered because the wirings are formed only by the aluminum group films. Accordingly, contact resistance is reduced, oxidation resistance is improved, and bonding is facilitated.

Title: Refrigerating cycle equipment and inverted device therefor
Inventor: KAMIMURA TOSHIYUKI
IPC: H02P6/08
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To reduce high-frequency leakage current without fail, even at a high switching frequency, by detecting a zero-phase current flowing from each phase winding of a brushless direct-current motor to earth creating a current having a waveform similar to that of the zero-phase current to forcibly cancel out the leakage current from the brushless direct-current motor. SOLUTION: Since high-frequency leakage current I1 flows to a direct current circuit 5, the currents, the magnetic of which is in proportion to zero-phase current, are detected using a zero-phase current detector 31. The output voltage of the zero-phase current detector 31 is class A push-pull-amplified using transistor 21, 33 to create a current I2 for canceling out similar to the zero-phase current in waveform. The current I2 for canceling out has such a polarity as to make the said current flow from earth E to a current canceling-out circuit 30. Based on the polarity and waveform, the high-frequency leakage current I1 is absorbed into the current canceling-out circuit 30 and is thereby forcibly canceled out. This enables reducing the high-frequency leakage current I1 without fail, even if the switching frequency of a switching circuit 11 is high.
