Title: Drainage structure for sanitary equipment
Inventor: HASE HIROSHI
IPC: E03D11/16
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To provide the repair method of a Japanese style stool which enables the short term of works by operation only from the installation floor of the Japanese style stool by improving work environment while reducing the number of operators in repair by conducting a repair to a new sanitary installation under the state in which existing Japanese style stool and drain pipes are left partially without removing all stool and pipes. SOLUTION: The floor exposed section of an existing Japanese style stool is removed, and an existing drain pipe is connected to an existing Japanese style stool trap section or cleaning mouth section, and buried in an underfloor mortar layer 11 under the state in which an existing drain pipe is left as it is connected. Accordingly, since a floor can be finished without removing the existing Japanese style stool and drain pipe, the term of works can be further shortened by operation only from the installation floor of the Japanese style stool.

Title: Distribution line fine grounding relay
Inventor: EMURA TOKUO
IPC: H02H7/22
Filed: 1994-09-29
Abstract: PURPOSE: To enable a fault circuit to efficiently interrupt without fetching a zero phase current of each circuit, by interrupting the circuit successively starting with a distribution line, with most frequent grounding fault in the past, based on increasing zero phase voltage of a bus in the case of generating the grounding fault in the distribution line. CONSTITUTION: In a distribution line bus, its zero phase voltage is detected by a grounding potential transformer GPT, and in a distribution line fine grounding relay, a processor 3 and an interface circuit 5 to breakers of each distribution line are provided. The processor 3 has a rank order memory 4 counting a number of times stored of generating a grounding fault in each distribution line. When zero phase voltage exceeds a setting value, based on a value of number of times of interrupting the distribution line stored in the rank order memory 4, a distribution line interrupting rank order is decided. This decision is performed based on a decreasing frequency of interruption of the distribution line. The distribution lines from the first to the n-th rank order, rearranged by this rank order, are successively interrupted by the breakers.

Title: Polygon mirror
Inventor: SAKAE HIDETOSHI
IPC: G02B26/12
Filed: 1989-09-11
Abstract: PURPOSE:To evade discontinuous cutting and to work an object surface with high flatness accuracy by forming a relief groove which is deeper than a working margin to width covering a hole concentrically with the center of rotation of a polygon mirror. CONSTITUTION:The relief groove 7 which is wider than the diameter of the hole 3 and has depth (t) larger than the working margin is formed concentrically with the axis 0 of rotation. Consequently, the surface 1 is fitted to a spindle 4 by a vacuum by aligning the axis 0 of rotation with the center of rotation of the spindle and when the surface is cut while rotated, a cutting tool 6 moves along the relief groove 7, so intermittent cutting is evaded. Lapping is the same in this regard. Consequently, the discontinuous cutting is not performed, so a defect in the working state of the periphery of the hole is eliminated and overall plane accuracy is secured.

Title: Controlling method of electric railcar
Inventor: NAKAMOTO NORIAKI
IPC: B60L7/14
Filed: 1984-11-07
Abstract: PURPOSE:To prevent a regenerative efficiency form decreasing due to regenerative failure by decreasing a voltage in the state that the regenerative amount is not large. CONSTITUTION:When a regenerative load decreases and a capacitor voltage 8 exceeds a slip frequency fS reduction starting voltage 72, slip frequency 9 is reduced to decrease the regeneration amount 11 to suppress the voltage 8 to exceed the overvoltage protective set value 71. If it decreases from the suppressing limit value 73 capable of suppressing the overvoltage at transient variation time only by the slip frequency 9, the control is stabilized by reducing the coefficient K1 of a motor voltage VM. Thus, not only the regenerative efficiency is increased, but pneumatic brake can be reduced.

Filed: 1985-10-23
Abstract: PURPOSE:To obtain a high speed and high quality thermal transfer recording apparatus independently of the surface configuration of a receiving article, by differentiating the physical property value at the time of cooling at certain temp. from that at a heating time of ink activated by thermal stimulation. CONSTITUTION:As ink 11, one has a supercooling characteristic is used and, when said ink is heated from ambient temper., the viscosity thereof is lowered as shown by a curve 50 to generate phase transition from a solid phase to a liquid phase but, even if the ink 11 is cooled to ambient temp. thereafter, the ink 11 holds a liquid phase for a certain time as shown by a curve 51. Because the ink 11 has the above mentioned supercooling characteristic, said ink 11 holds melt viscosity even if the ink is left for a long time from a heating process to a transfer process and cooled to the vicinity of ambient temp. and, therefore, by pressing the ink by a transfer blade 46, the transfer to receiving paper 12 is enabled. However, if the variation in room temp. generates, the temp. of the ink at the time of transfer also changes and transfer optimum viscosity is not stably kept and, therefore, the ink is appropriately heated through the transfer blade 46 heated and controlled by the electric heater 56 and temp. sensor 57 provided on the back surface of the transfer blade.

Abstract: PURPOSE:To decrease noise to be generated in wiring within a chip carrier and to reduce amplitude as well as erroneous operation in timing at the time of high speed operation of a GaAs IC by shaping a chip to be polygonal and mounting the chip in a package whose shape is analogous thereto. CONSTITUTION:An equilateral octagonal chip 1 which is cut out of a wafer by a laser or the like is mounted at the center of a chip carrier, and is connected to broken lines 4 within the carrier from a chip pad 2 through a bonding wire 3. Because the chip is octagonal, the geometry difference between the middle part and the corner part of wiring within a cavity is reduced, whereby the wiring intervals are uniform, the ratio of the corner part to the middle part being improved to (2+2<1/2>)<1/2>/2(-0.9). The difference in wiring length between the middle part and the corner part is only 8%, while erroneous operation is virtually none. Furthermore, that bonding wire length at the corner part can be shortened can reduce waveform distortions due to characteristic impedance imbalance.
