Title: Working pos terminal number controller applying fuzzy control
Inventor: OYAMA MASAKI
IPC: G07G1/14
Filed: 1989-05-22
Abstract: PURPOSE:To eliminate the congestion in a store by applying the fuzzy control to decide the optimum number of working POS terminals within the store. CONSTITUTION:An incoming/outgoing customer controller 1 counts the number of incoming/outgoing customers every unit time based on the outputs of the incoming and outgoing customer sensors set at the gate of a store and obtains the difference (x) between the incoming and otugoing customers counted every unit time based on the counting result. A differentiator 2 obtains the differential value DELTAx of the difference (x). These values (x) and DELTAx are given to a fuzzy controller 3, and the controller 3 obtains the number (y) of working POS terminals by the fuzzy inference. The number (y) is outputted to a store controller 4. The controler 4 controls the working states of terminals 5 based on the number (y). Thus the congestion can be quickly eliminated at the installed parts of terminals 5 in a store.

Filed: 1978-10-19
Abstract: PURPOSE: To shorten working hours and also to prevent cable insulator and cable sheath from thermal deformation by keeping the connection of an insulated cable conductor at high temperatures and cooling down the cable insulator and cable sheath forcedly.  
     CONSTITUTION: Ends of rubber and plastic cables 1, 1' to connect are stripped, a cable conductor 2 is connected to another cable conductor 2', and then a thermally- fusible rubber/plastic wound layer 3 is formed on its outer periphery over both the cables. An eddy current is generated on the cable conductors 2, 2' from carring a high-frequency current through high-frequency coil 4, and thus the tape-wound layer 3 is heated and fused. A cable sheath and cable insulators are cooled below 105°C forcedly at the same time by feeding a cool air or circulating a refrigerant to cooling devices 6, 6' on the cable sheath and the cable insulators 5, 5' in the neighborhood of the wound layer 3.

Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To reduce a noise, ensure durability and increase operation efficiency. SOLUTION: The lever member 11 of a swinging fulcrum type lever device 10 swings around this fulcrum R, while a dynamic point Q carries out the circular movement by the rotation of a crank pin 20 and the fulcrum R moves vertically on an L-L line by a fulcrum regulator 21. A action point P carries out the elliptic movement whole major axis is the lateral direction and the movement of the lateral direction of this elliptic movement is transmitted to respective pistons 8, 9 through respective connecting rods 14, 15 and the gas is sucked and compressed alternately in respective cylinders 4, 5. As respective rollers 22, 23 of a fulcrum regulator 21 are always contacted only with oneside guide plates 26, 27 respectively and do not collide with respective guide plates 26, 27 and not slip at the reverse turn time, the noise and wear by the collision and slip can be reduced.  As respective pistons 8, 9 are moved integrally with the action point P and moved at a higher speed than a first half in the latter half of the compression stroke and moved at the higher speed than the latter half in the first half of the suction stroke, the compression efficiency and suction efficiency are favorable.

Title: Nox removal device of diesel engine
Inventor: SHIMIZU NORIO
IPC: F02B3/06
Filed: 1989-05-23
Abstract: PURPOSE:To make a NOx device cheap and simple in its structure by controlling a flow governing valve based on the direction of displacement of a volume regulation rack of a fuel injection pump. CONSTITUTION:When the load of an engine E increases, the volume regulation rack 8 of a fuel injection pump 6 is displaced toward the volume increasing side. At this time, a rack position detector 7 position-detects the displacement of the volume regulation rack 8 toward the volume increasing side, then a control device 10 controls a flow governing valve 3 to the valve-opening side to increase the supply volume of denitration agent to a reactor 2. Reversely, when the load of the engine E decreases, the rack position detector 7 position- detects the displacement of the volume control rack 8 toward the volume decreasing side, and the supply volume of denitration agent to the reactor 2 is decreased. Thus, simply by installing the rack position detector 7 in place of a NOx sensor, the supply of ammonia can be controlled by increasing or decreasing the fuel injection quantity. A NOx removal can thus be made cheap and simplified in its structure.

Title: Liquid level gage
Inventor: KAWAI MAKOTO
IPC: G01V3/10
Filed: 1987-05-26
Abstract: PURPOSE:To make it possible to detect the amount of liquid in a container, in which relationship between the height of the liquid surface and the amount of the liquid is nonlinear, accurately, by changing the winding density of a coil in a coarse winding part in the coil comprising a dense winding part and the coarse winding part, continuously or stepwise. CONSTITUTION:Liquid 2 is put into a container 1, in which the cross section is changed in the direction of a height H. Then an amount Q of the liquid increases nonlinearly with the increase in height (h) of the liquid level. Then, a conductor ring 8 in a sensing part A also rises up. A coil 7 is wound around a core so that the winding density of a coarse winding part 15 of the coil 7 is changed continuously or stepwise in the direction of the height H of the container. The mutual inductance between the ring 8 and the coil 7 is also changed nonlinearly. The degree of the change in winding density of the coarse winding part 15 is set so that the differential coefficient at the same liquid-level height (h) satisfies ¦dQ/dh¦=¦dL/dh¦. Therefore, the output of a converter circuit B, which converts the inductance L into a voltage and the like, and the liquid amount Q have the linear relationship. The liquid amount, which is displayed on a display part C, agrees with the liquid amount Q in the container 1.

Title: Gathering object feed device

IPC: B65G47/82
Filed: 1994-05-20
Abstract: PURPOSE:To stably push out a specific number of gathering objects so as to feed them even if the stop position of a lift device is dispersed by arranging a position detecting device and a pusher of a push-out device on a base plate. CONSTITUTION:When a detecting roller 38 is contacted with the upper face of a gathering object 21 on the uppermost position and the upper end part of a detecting rod 36 reaches the position of a detecting sensor 35, a signal is output from the detecting sensor 35 to a control device. It is assumed that a lift device receives a signal from the control device, and the upper face of the uppermost gathering object stops on the position higher than the reference position. At this time, an upper face presser member 34, a connecting rod 44, and a moving member 33 are elevated together with a base plate 28 by the same degree as the uppermost gathering object 21. A push plate 47 and the base plate 28 are integratedly formed, and hence the pusher 50 of a push-up device 24 is elevated by the same degree as the upper face presser member 34. Therefore, the distance L between the upper face of the uppermost gathering object 21 and the lower end face of the pusher 50 is always constant, and hence the prescribed number of the gathering objects can be pushed out.
