Abstract: PROBLEM TO BE SOLVED: To provide a coppery sintered friction material in which coefficient of friction is stabilized in the early stage owing to fine, spherical, had grains and also fluctuations in the coefficient of friction are minimized. SOLUTION: This friction material consists of a coppery composite powder material prepared by mixing aluminum (Al)-containing hard grains with a coppery powder material consisting of copper (Cu) or a copper alloy composed essentially of copper (Cu) and free from aluminum (Al). The grain size of the hard grains dispersed in the metallic matrix of the coppery sintered friction material is regulated to <=8 μm, and aliuminum(Al) is contained by <=28% on a weight percentage basis to the metallic matrix. The coppery composite powder material is press-compacted into a green compact, and this green compact is sintered in a nonoxidizing atmosphere or reducing atmosphere at 700 at 1000 deg.C.

Title: Input circuit for voltage/current measuring instrument
Inventor: YAMADA YOSHIO
IPC: G01R19/00
Filed: 1994-06-16
Abstract: PURPOSE:To avoid the danger when touching a current measuring terminal at the time of high voltage floating measurement without relying on a mechanical structure by providing a voltage measuring terminal, a current measuring terminal, switches, a common terminal, and a current detection resistor. CONSTITUTION:A current measuring terminal 22 is connected through a switch 36 with one end of a current detection resistor 26 and the fixed contact (b) of a switch 34. At the time of voltage measurement where a measuring probe is connected with a voltage measuring terminal 20 and a common terminal 24, the movable contact of the switch 34 is connected with a fixed contact (a). The voltage between the terminals 20 and 24 is fed to an A/D converter ADC 38. The switch 36 interlocked with the switch 34 is thereby turned OFF to disconnect the conduction path between the terminals 22, 24. Since the voltage at the terminal 24 does not appear at the terminal 22, no danger is imposed on the human body even if a person touches the terminal 22 at the time of floating voltage measurement.

IPC: G05B17/02
Filed: 1986-07-03
Abstract: PURPOSE:To simplify the operation of an actuator, to increase the speed of optimum control, to absorb the influence of disturbance and to reduce the load of an information amount by providing a nonlinear operation circuit and a control circuit equipped with a model process. CONSTITUTION:Correcting circuits 21-23 multiply the deviation between a set value 101 and a process output 103 by a proportional constant Kp, the time integral value of an output 103 by a proportional constant Kd, and the output difference between the model process 26 and a process 30 by a proportional constant Km. Those outputs are summed up by an adder 34. A nonlinear operation circuit 25 inputs the sum output and controls its pulse width to output a manipulated variable 102. The process 26 which inputs the manipulated variable 102 is simulated in a control circuit 20 by analyzing an actual process itself and describing its characteristics on the computer by a discrete time system. The process, therefore, includes no disturbance and inputs its manipulated variable, so its output and the output of the process 30 are compared with each other to extract the influence of disturbance. Consequently, the manipulated variable 102 is determined by three elements which are the set value and the outputs of the processes 30 and 26.

Title: Floor heating panel
Inventor: NAKAGAWA NAOHARU
IPC: F24D5/04
Filed: 1987-06-24
Abstract: PURPOSE:To obtain a comfortable floor panel without feeling cold draft by a method wherein the suction ports of hot air are installed at the periphery of a hollow panel and the suction ports and an air blower are connected by an air passage. CONSTITUTION:Air is sucked from an inlet port 6 by an air blower 8 and heated by a header 7 and passes through an air passage 9 and then sent to suction ports 4 and 5 and flows through the inside of a hollow panel 1 and ejected from discharge holes 3 into the interior of a room. At that time, the temp. distribution on the upper surface 2 is formed in such a manner that the temp. of the location near the ports 4, 5 is high and as the location approaches the neighborhood of the center part, its temp. is reduced. The distribution of the amount of hot air ejected from the holes 3 is formed in such a manner that a large amount of hot air is ejected near the ports 4, 5 because of its high pressure and the amount is reduced as the location of the holes approaches the neighborhood of the center part. As a result, the temp. distribution in the room is realized in such a manner that the temp. is high at the parts of the panel periphery facing each other and low in the center and stream distribution where cold draft does not exist on the peripheral surface of the panel 1 is obtained.
