Patent JP-S6332378-A (JP)
Title: Short-circuit position detector
Inventor: SEKIYA SATOSHI
IPC: H05K3/00
Filed: 1986-07-25
Abstract: PURPOSE:To accurately detect a short-circuit position in a short time by supplying a current from one terminal of one conductor to an optional point of the other conductor and measuring the potential difference between one terminal of one conductor and the other terminal including the short-circuit position. CONSTITUTION:When the constant current is supplied to current terminals T1 and T2, the constant current flows from a point N1 on a conductor P1 to the short-circuit position N5. The potential difference is measured by voltage measurement terminals T3 and T4 brought into contact with the points N1 and N2 on the conductor P1. This potential difference is generated by the flowing of the constant current from the point N1 to the short-circuit position N4 and proportional to the conductor resistance from the point N1 to the short-circuit position N5 and therefore proportional to the conductor length as long as the resistivity is constant. For the purpose, a computer A4 stores the resistivity corresponding to data indicating the kind of the conductor which is inputted from an input circuit A6 and the resistance value is calculated from the potential difference between the points N1 and N2 read out of an A/D converter A3 and the current value of a constant current circuit A1 and this resistance value is divided by the resistivity to find the conductor length from the point N1 to the short-circuit position N5 and display it on a display device A5, thereby detecting the short-circuit position.

Title: Pretreatment of sintered ore raw material and sintered ore raw material for iron making
Inventor: MATSUMURA TOSHIHIDE
IPC: C22B1/16
Filed: 1992-06-08
Abstract: PURPOSE:To obtain the sintered ore raw material having high-strength without increasing consumption of heat quantity and degrading productivity by mixing iron ore contg. water of crystallization at a high ratio with limestone powder and pelletizing the mixture at the time of using this iron ore as the sintering raw material. CONSTITUTION:The high-water of crystallization content iron ore 1, such as goethite ore, is mixed with the fine powder limestone 2 (more preferably the whole or part thereof is pulverized to <=125mum grain size) and the mixture is pelletized by a pelletizer 3. The resulted pellets are mixed with SiO2-contg. auxiliary raw materials and solid fuel 5, etc., such as coke, by using a drum mixer 4, by which the sintered ore raw material is obtd. The contact area of the high-water of crystallization iron ore 1 with the fine powder limestone 2 is increased and the formation of a calcium ferrite melt in a sintering stage is accelerated by this method. This melt packs the coarse pores and cracks formed in the ore 1 in the sintering stage. Consequently, the high- strength sintered ore raw material is obtd. without increasing the consumption of heat quantity and degrading the yield, strength and productivity by the coarse pores and cracks.

Title: Fluorescent character display device
Inventor: SAKAUCHI MASANORI
IPC: G09F9/30
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To save power without making a circuit structure complicated. SOLUTION: A display pattern 8B is divided into plural display regions 8a-8e. Grid electrodes 15a-15e are arranged above the display pattern 8B by dividing it so as to cover all the display regions 8a-8e. In each of the display regions 8a-8e, segments 9 (constantly lit segments 9a, high-frequency segments 9b, low-frequency segments 9c) are arranged by being grouped according to the frequency of lighting. A drive circuit stops the application of a voltage to segments arranged in display regions which are not lighting objects, applies the voltage to the grid electrodes covering the respective display regions which are the lighting objects while scanning them sequentially, and outputs segment data to positive electrodes of the lighting objects to synchronize them with the application of the voltage to the grid electrodes.

Title: Multiple disc clutch and multidisc type brake
Inventor: YOSHIDA TOSHIYASU
IPC: F16D25/063
Filed: 1988-07-15
Abstract: PURPOSE:To shorten a span of clamping time as well as to reduce a clamping shock by varying a sectional area of an oil passage, feeding a pressure chamber between a cylinder and a piston with oil pressure with the movement of the piston. CONSTITUTION:A cylinder side oil passage 32 is installed in an inner cylinder part 10b of a clutch drum 10. This cylinder side oil passage 32 is constituted of a ring groove 32a and a hole 32b, while a piston side oil passage 34 is installed in a piston 12, and this piston side oil passage 34 is composed of a casting hole 34a and a hole 34b. With this constitution, since a sectional area of the oil passage feeding a pressure chamber 30 between a cylinder 10 and the piston 12 with oil pressure is varied to some extent, this piston 12 is quickly moved immediately after movement of the piston 12, and this moving speed of the piston 12 is lowered at the final stage of clamping. Therefore clamping time is shortened, and a clamping shock is thus reduced.

Title: Automatic steering device for vehicle
Inventor: SAKAI KATSUHIRO
IPC: G05D1/02
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To perform precise automatic parking by preventing the occurrence of dislocation in a traveling locus while minimizing the time required for automatic parking. SOLUTION: This automatic steering device steers front wheels with a steering actuator based on a traveling locus stored in advance as a relation of the turning angle θref of a steering wheel relative to the traveling distance X of a vehicle. The limited vehicle speed VL1M decreasing with an increase in the turning angle θref is set in advance, and warning is generated for a driver, or the vehicle is automatically controlled so that actual vehicle speed may not exceed the limited vehicle speed VL1M. It is thus possible to prevent the time required for automatic parking from increasing due to the limit on higher vehicle speed than it needs while permitting automatic parking to be performed precisely by preventing the occurrence of dislocation in the traveling locus due to excessive vehicle speed.

Filed: 1981-11-05
Abstract: PURPOSE:To reduce the number of signal lines requesting use of bus considerably, by permiting a card, to which the highest binary code is assigned, out of plural competing master cards, to use a common bus. CONSTITUTION:If master cards 7(2) and 7(3) transmit code 1110 and code 1101 respectively from their own code transmitting circuits 7A to signal lines *BR Q3-*BRQ1 requesting use of bus simultaneously, code signals *BRQ3-*BRQ1 are the OR output of respective digits between codes transmitted from cards 7(2) and 7(3), namely, 1111. In cards 7(2) and 7(3), code 1110 and code 1101 transmitted from themselves are compared with signal 1111 on a code signal line by code comparing circuit 7B. When they do not coincide with each other, successive checking circuits 7D checks individual digits successively to detect a digit where they do not coincide with each other, and control outputs for circuits 7A are transmitted from circuits 7D to stop the output of the code at the time when this digit is detected. As the result, the card 7(2) uses the bus in preference to the card 7(3).
