IPC: G06F3/12
Filed: 1990-10-31
Abstract: PURPOSE:To speed up a processing of data access from a bit map memory by generating logical arithmetic data according to a frequency of CPU access. CONSTITUTION:The circuit is equipped with a register means 1 which holds memory access control data corresponding to input data and an access information arithmetic means 3 which calculates the CPU access frequency and respective shift-out data quantities accompanying data transfer according to the memory access control data.

Title: Dielectric coaxial resonator
Inventor: MAKIMOTO MITSUO
IPC: H01P7/04
Filed: 1989-11-09
Abstract: PURPOSE:To form a resonator of a small size with high no load Q by inserting and fixing a 2nd coaxial line to a 1st coaxial line so that an open end of the 2nd coaxial line is overlapped onto a short-circuit end of the 1st coaxial line in two cylindrical dielectric bodies whose outer diameter differs from each other. CONSTITUTION:A 2nd coaxial line R2 is inserted to a 1st coaxial line R1 so that open ends 14a, 14b and short-circuit ends 13a, 13b of the 1st and 2nd coaxial lines R1, R2 are made coincident. Then the contact faces are connected electrically and mechanically to form a composite resonator R3 of dual coaxial constitution. The short-circuit face 13a of the 1st coaxial resonator R1 is used as a short-circuit face 15 of the composite resonator R3 and an open end 14b of the 2nd coaxial resonator R2 is used for an open end 16 of the composite resonator R3. The resonator R3 acts like a coaxial resonator whose one end is short-circuited and whose other end is opened comprising two transmission lines. The adoption of a loopback coaxial resonator allows the size of the resonator to be 1/2 of a uniform line resonator or below and further miniaturization is attained by the selection of Z1>Z2. Since no waste space exists, the deterioration in no load Q is less.

Title: Distance relay
Inventor: KUROSAWA YASUHIRO
IPC: H02H3/02
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To improve reliability by making effective the operation output of a short-circuiting distance relay element when a phase where a sensitivity constant value is established coincides with the single-phase operation phase of the short-circuiting distance relay element, and by making effective the operation output of the short-circuiting distance relay element when at least two operation phases of the short-circuiting distance relay element exist. SOLUTION: First, level judgment is made in a lead phase/delay phase with bc phase as reference (step 201). According to differential absolute value judgment ||Vab|-|Vea||<Vk of the voltages of a sound phase, the size comparison can be established. Then, for the bc phase, a Vdc level is judged (steps 202 and 203). In this case, a delay phase Vab is used for comparison. The absolute value differential judgment ||Vab|-|Vca||<Vk is made, the size comparison cannot be established according to the relationship of a sound-phase voltage value >> a fault-phase voltage value, and the level width of a sensitivity constant value Vk is detected in the next step.  The comparison judgment of the absolute value differential judgment ||Vab|-|Vca||<Vk is established, and the bc phase is identified (step 209). When the judgment is established and is not established, judgment processing is bypassed.

IPC: H01L23/48
Filed: 1985-12-26
Abstract: PURPOSE:To prevent any no resin filled part as well as any notch on package from occurring by a method wherein a diestage of lead frame is arranged in a cavity inclined by + or -45 deg. to the runner to be connected to a gate orthogonal to the runner. CONSTITUTION:A gate 13 of bottom force 11 is formed to extend from a runner 15 almost orthogonal thereto. One corner of a lead frame 21 comprising a diestage 22 four sides of which are arranged with leads 23 is connected to an end of the gate 13. Each side of diestage 22 is arranged in a cavity inclined by + or -45 deg. to the runner 15 to be resin-injected from the gate 13 for mold formation. The resin flow is improved by changing its direction only by one degree. Besides, when a package is lifted along the runner 15 to isolate the package from the resin in gate 13, the cut off line corresponds with the boundary line 16. Through these procedures, any no resin filled part as well as any notch or protrusion on package can be prevented from occurring.

Inventor: WATANABE HIDEAKI
IPC: B23B19/02
Filed: 1987-11-18
Abstract: PURPOSE:To prevent the variation of clearance by detecting the variation of the clearance between a turning shaft and fluid bearing caused by heat through the flow-rate variation of pressurized fluid fed into the clearance and controlling the supply of electric power to the Peltier elements of a cooling device on the basis of this flow-rate variation. CONSTITUTION:The heat generated in a clearance 23 by the rotation of a turning shaft 5 is cooled by Peltier elements 27 to a lower temperature to cool a fluid bearing 4 and the turning shaft 5, and to be cool the pressurized fluid flowing in the clearance 23. Variation is caused in the clearance 23 by the heat generated between the fluid bearing 4 and the turning shaft 5. Consequently, the flow rate of the pressurized fluid supplied to the fluid bearing 4 also varies, and this is detected by a flow-rate detector via these elements. Then, the electric signal corresponding to that is input into a current controller, and on the basis of the input, the electric power for cooling is supplied to drive the Peltier elements 27. Thus, the bearing part can be cooled under the optimum condition corresponding to the actual clearance, so that the reduction in the rotational accuracy attributable to the variation of clearance can be prevented.

Filed: 1986-12-09
Abstract: PURPOSE:To shorten the fingerprint collating time by dividing the fingerprint data into plural areas for registration and storage and carrying out coincidence of fingerprint data among the prescribed areas in response to the type of collation. CONSTITUTION:A keyboard contains A, B and C keys showing the types of collation in addition to ten keys.
