Title: Semiconductor integrated circuit electromigration reliability verification method and its device
Inventor: MURAI SHUZO
IPC: G06F17/50
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To detect a part where electromigration induced by a current of instantaneous high density (current pulse of large amplitude) may rapidly progress to cause a trouble in a CMOS semiconductor integrated circuit which is to be verified. SOLUTION: Transistor constitution data (type, number, and width of channel) with regard to combinations of transistors which are comprised in a verification net to change it in a logic state are detected, and the wiring resistance and load capacitance of the verification net are calculated (A1 ). Then, the maximum value out of the current peaks of the verification net for each combination is calculated on the basis of the transistor constitution data and the wiring resistance and load capacitance of the verification net (A2 ). Then, the current density peak of a circuit wiring is calculated on the basis of the maximum value of the current peaks and the shape of the wiring (A3 ). Then, it is checked whether the calculated current density peak meets the limiting value of a current density peak as design specifications of electromigration.

Title: Photoelectric detector for color selector
Inventor: SATAKE TOSHIHIKO
IPC: G01N21/15
Filed: 1980-09-20
Abstract: PURPOSE:To achieve a accurate assembly and disassembly and servicing of mechanical parts along with a handly cleaning by means of a photoelectric chamber provided in a particle selector chamber in such a manner as to be dustproofed at the front with a transparent window. CONSTITUTION:When a different particle is detected with a photodetectors 16 and 17 in a flux 3 of particles from a particle downflow chute 2 provided with a partical feeder 1 at the upper portion thereof, it is dispersed and selected on a jet air from a jet nozzle 21. Dust attached to the particle will be dispersed and polute the outer surface of the window 10. As a result, when the quantity of light transmitted from light sources 4, 5, 6 and 7 is reduced to lower the performance of the selection, a photoelectric chamber 8 is pulled out holding a grip section 24 until the window 10 is exposed outside the machine frame. After cleaning, the photoelectric chamber 8 is inserted in the reverse order to restore in place. This enables efficient cleaning work while eliminating deviation in the optical construction due to reservicing of the cleaning work. Thus, a highly accurate selection can be done.

Filed: 1988-05-31
Abstract: PURPOSE:To prevent the red-eye effect for flash photographing or photograph without auxiliary light on demand by setting the auxiliary light to a visible state or an invisible state in accordance with position selection of a switch changeover member. CONSTITUTION:When a switch changeover member 1 is slided left and is set to a light-off position, a visible-ray cut filter 3 is moved to the front of an auxiliary light lamp 2.

IPC: H01F30/14
Filed: 1979-10-12
Abstract: PURPOSE:To equalize three phases in the phase converting device which converts three phases to a single phase, by utilizing the exciting current of a transformer without using a balancing reactor or a balancing capacitor. CONSTITUTION:The transformer windings are connected in the method of Scott connection. The main transformer is wound around the leg I, and the T transformer is wound around the leg III. A winding 7 is provided around the leg II wherein the magnetic fluxes which are the vectorial sum of the fluxes from the leg I and leg III. One end (w) of the secondary winding of the main transformer is connected to one end (w) of the secondary winding of the T transformer. The winding 7 of the leg II is connected between the other ends (u) and (v) of both transformers. If the number of the turns of the winding 7 is twice that of the secondary windings of the main transformer and the T transformer, no cross current is generated in the connected secondary windings. If the number of turns of the winding 7 is changed from the twice that of the secondary windings, the cross current is generated in the connected secondary windings.

Title: Control device for electric rolling stock
Inventor: KAMEI KOUICHIROU
IPC: B60L3/06
Filed: 1981-08-24
Abstract: PURPOSE:To reduce the capacity of a reactor and to prevent the deterioration in the rectification of a control device for an electric rolling stock by flowing an armature current through a GTO thyristor during an ordinary operation and flowing the current through the reactor only when the current abruptly increases. CONSTITUTION:An armature current flows through a GTO thyristor 8 during power drive operation, and flows through a GTO thyristor 9 during the regenerative operation. On the other hand, when a line voltage abruptly varies so that the armature current rapidly increases, the varied component is supplied through a transformer 10 to a gate circuit of the thyristor 8 or 9. The secondary side voltage generating direction of the transformer 10 is determined to the direction of flowing a gate current to turn the thyristor 8 or 9 OFF when the armature current is abruptly increased. Accordingly, when the armature current is increased rapidly due to the variation in the line voltage, the thyristor 8 or 9 is interrupted, the current flows through the reactor 4, thereby suppressing the peak current.

Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To prevent generation of cracks in a region of a member end caused by medium to small earthquake by insulating a beam member concrete at a cross part of a column and a beam from a column part concrete to be attached thereto. SOLUTION: In a cross part of a column Band a beam A of a reinforced concrete structure, a member concrete of the beam A and a member concrete of the column B to be attached to the end thereof are formed in an insulating manner so as to be non-integrated.

Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To use the total transmission capacity of the system efficiently by counting cells with a write request described in them before and after occurrence of the request at its own terminal equipment and writing the request after passing cells by the number of requests so as to use each channel uniformly. SOLUTION: Terminal equipments 131-137 describe a write request to cells in which no write request is described and send the cells via optional channels 111-116 among a plurality of wavelength multiplex channels. Each of the terminal equipments 131-137 receiving the cells uses each of request counters 151-157 to count the number of requests written in cells sent through each channel while distinguishing before and after the occurrence of the write request at its own terminal equipment. Each of the terminal equipments 131-137 having a write request passes write enable cells on each channel by the number of write requests of the terminal equipment to which the cells are sent and then writes the request to a write enable cell received next and then sends the resulting cell.  Thus, all wavelength multiplex channels are controlled by one communication protocol to use all the channels uniformly thereby using the total transmission capacity efficiently.
