Title: Conductor device
Inventor: HISAOKA TOSHIYUKI
IPC: H01F27/04
Filed: 1979-03-26
Abstract: PURPOSE: To reduce an electromagnetic force which acts to a conductor, to simplify a conductor support, to utilize a conductor of low ridigity and to provide an economic conductor device, by changing the disposition dimensions of pairs of conductors such as lead wires.  
     CONSTITUTION: Currents are caused to flow forward and backward through a pair of conductors 31, 32 and another pair of conductors 33, 34. The distance A between the conductors 31, 32 and between the conductors 33, 34 is set larger than that between the conductors 32, 33. A force, which acts between two conductors of W in width at a distance of A when a forward and a backward currents flow through the conductors, is shown by a formula on the simplifying assumption that the currents concentrate to the center of the thickness of the conductors and are uniformly distributed along their width. In the formula, F denotes the electromagnetic force per unit length of the conductors and I denotes a current per conductor. An electromagnetic force complying with the formula is applied to the conductor 31 leftward from the conductor 32, rightward from the conductor 33 and leftward from the conductor 34. This results in reducing the electromagnetic forces which act among the conductors. Therefore, supports for te conductors can be simplified and their rigidity can be reduced. Cost is thus diminished.

Title: Installation of protector
Inventor: KAMEI HITOSHI
IPC: E21D19/00
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To easily fabricate a protector even when unevenness exists at a foundation by a method wherein laying girders are temporarily laid on the foundation and supports and a roof fabricated beforehand in a specified length are mounted and fixed thereon, and the laying girders are fixed lastly to the foundation. SOLUTION: A protector 1 for protection against falling matters is composed of laying girders 11, supports 12 and a roof 13. The supports 12 are connected at their upper and lower ends with connecting steel plates 12a and fabricated in a specified length with reinforcement bars 12b fixed diagonally beforehand at another site, and the roof 13 comprising lengthwise girders 13a, breadthwise girders 13b and covering plates 13c is fabricated likewise. Then, the layhing girders 11 are laid temporarily on a foundation 100, and the supports 12 and the roof 13 are mounted successively thereon and fixed, and the laying girders 11 are fixed lastly to the foundation 100 with anchors. Thereby, joining by bolts of the supports 12 and the roof 13 to the laying girders 11 can be made easily even when unevenness exists at the foundation 100.  Although a slight difference in level is produced between respective ends of each of protectors 1 fabricated respectively in a specified length, no problem exists strength- wise even though the protectors are not connected together.

IPC: B60L7/24
Filed: 1993-02-26
Abstract: PURPOSE:To fully charge a battery by regenerative brake while suppressing a decrease in response by increasing a distribution of a mechanical brake torque as a depressing speed of a brake pedal is accelerated. CONSTITUTION:A controller 11 has a regenerative brake controller 12 for setting a mechanical brake torque value and a regenerative brake torque value, and a hydraulic control unit 13 for increasing/decreasing the brake torque by increasing/decreasing hydraulic pressure of a master cylinder 2 in response to a mechanical brake torque signal sent from the controller 12. The controller 12 also has a brake torque distribution map in addition to a brake torque map, which is so set as to gradually increase a distribution amount of the mechanical brake torque as a brake stroke speed is accelerated as a brake pedal 1 is depressed. Accordingly, since energy recovery efficiency at the regenerative brake is enhanced, a battery can be charged more during traveling.

Title: Molding tool of thermosetting resin material
Inventor: KAGEYAMA YASUSHI
IPC: B29C39/32
Filed: 1986-02-21
Abstract: PURPOSE:To prevent thermosetting resin from leaking outside a molding tool even under the condition that the pouring pressure is high and the viscosity of pouring resin is low by a method wherein a sealing mechanism, which accelerates the setting reaction of thermosetting resin material, is provided on the mold mating surface either of a bottom force or of a top force. CONSTITUTION:Thermosetting resin material M is supplied through pipes 13a to a mixer 12 so as to be fully mixed in order to be poured from a pouring gun 11 through a sprue hole 1b into a molding space part 5, which is formed by both forces 1 and 3. The thermosetting resin material M, which is poured in the molding space made by both the forces 1 and 3, permeates a fibrous base material W (not shown in fig.), which is set on the molding surface 3a side of the bottom force 3 in advance, and reaches the gap H (not shown in fig.) made between electrodes 8a and 8b, while discharging the air from the molding space part 5. The thermosetting resin material M reached the gap H between the electrodes 8a and 8b spontaneously generates heat in its interior by receiving high frequency electric field generated in the gap H so as to rapidly proceed the setting reaction in order to set itself. In the end, all the air in the molding space part 5 is discharged outside the forces and the resin material sets in the state that the fibrous base material is filled with the resin material, resulting in perfectly sealing the periphery of the molding space part 5 and preventing the resin material from leaking out of the forces.

Title: Method for controlling bath temperature
Inventor: SEO MASAMI
IPC: F24H1/46
Filed: 1994-03-09
Abstract: PURPOSE:To shorten a time required for causing hot water within a bath tub to reach a set water level and a set temperature by a method wherein hot water of temperature determined in response to a calorie of remained water within the bath tub and a calorie of hot water when a bath is boiled up is fed into the bath tub. CONSTITUTION:It is determined whether water remains lower than a set water level within a bath tub or not in response to an output signal value of a water level sensor (ST1) and if there remains water, its amount is calculated (ST2). Water amount required for the water in the bath tub to reach a set water level is calculated (ST3), a temperature of the remained water is detected by a bath temperature sensor (ST4), and a temperature of hot water feeding is calculated in such a way that an entire calorie of all hot water when the hot water reaches a set temperature of the bath and the water level in the bath is equal to a sum of calorie of the remained water and calorie of hot water to be added (ST5), and then feeding of hot water to the remained water is started. If a bath-taking state is detected in the case hot water is being fed at a high temperature, the hot water feeding temperature is decreased down to an appropriate temperature (ST8). In the case that a bath-taking is not detected, the hot water feeding at a high temperature is continued and a valve is closed when the set water level is reached, a hot water boiling means is stopped so as to discriminate if a temperature of the bath tub is equal to the set temperature.

Filed: 1978-03-31
Abstract: PURPOSE: To make it possible to perform distance detection exactly and surely in a shortest time by subjecting the image scanning output to a proper processing to obtain always accurate binary image data without waste even in case that the integration time of a photo sensor array unit is changed.  
     CONSTITUTION: The peak value of the image scanning output is detected by peak value detector circuit 12, and it is discriminated by reference voltage setting circuit 15 whether the peak value is within a prescribed set voltage range or not. That is, in case that the detected peak value is within the voltage range set by circuit 15, binary image data based on the voltage level obtained on a basis of this peak value is obtained. Meanwhile, in case that the detected peak value is without the voltage range set by circuit 15, the integration time of a sensor unit is changed, and binary image data based on a specific voltage level within the voltage range set by circuit 15 is obtained. As a result, distance detection can be exactly and surely performed in the shortest time.
