Title: Heating element
Inventor: WATANABE TORU
IPC: H05B3/06
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To facilitate the working and to extend the service life by arranging a plurality of heating wires, spirally winding them, and electrically connecting both ends of each heating wire to each other. SOLUTION: Two or more heating wires 1 such as nichrome wires are simultaneously spirally worked so that each heating wire 1 is axially arranged, and both end parts of a plurality of such heating wires 1 are electrically connected to each other in parallel by crimp sleeves 2 or the like. Each heating wire 1 is preferably wound so as to form a space 3 every turn. According to such a structure, the spiral working with a small spiral diameter, compared with the thickness of the heating wire 1 can be performed without changing the using voltage. Although it is difficult to spirally work a thick heating wire with a small diameter in order to form a core wire for a sheath heater, a heating element can be constituted without raising the resistance by arranging and spirally winding a plurality of thin heating wires and electrically connecting both ends of each heating wire to each other.

Title: Electromagnetic relay
Inventor: SAKO KAZUMI
IPC: H01H50/16
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic relay having a high insulating characteristic by protrusively arranging an almost L-shaped insulating wall to partition a movable iron piece and a movable contact piece on an upper surface of a base block, and constituting so that an end part of an insulating stand of a movable block is extended up to overlapping with at least the insulating wall. SOLUTION: In this electromagnetic relay, a recessed part arranged on an under surface of an insulating stand 34 is supported by being fitted to a projecting part of a base block 20. In this electromagnetic relay, a spatial distance between a movable contact piece 32 and a movable iron piece 33 is, for example, about 0.9 mm. However, since a movable block 30 is installed on a base block 20, an almost U-shaped insulating wall 27 partitions the movable iron piece 33 and the movable contact piece 32. Therefore, the creeping distance between both becomes long, and an insulating characteristic becomes high. Next, both end parts 34c and 34d of the insulating stand 34 extend long, and overlap with the insulating wall 27. Therefore, the creeping distance between both becomes further long, and the insulating characteristic is improved.

Title: Burnout condition monitoring method of metal refining furnace
Inventor: HATONO TETSUO
IPC: C21C5/46
Filed: 1980-03-28
Abstract: PURPOSE:To estimate the burnout condition of refractories near the tuyere by capturing the intermittent impact noises produced from a furnace body, converting the same to electric signals, and quantitatively analyzing the intensity or production frequencies thereof. CONSTITUTION:An oxygen gas and an argon gas are blown through a tuyere 1 into a furnace. A sound collecting horn 8 is mounted on the outside wall of the furnace body 4, and a microphone 5 is put therein. The outputs of the microphone 5 are con verted to electric signals which are recorded as production frequencies by way of a band pass filter, a rectifying circuit, a smoothing circuit, a comparator and a counter. Also, they are recorded as intensity by way of an integrating network from the smoothing circuit. Since the burnout of the refractories near the tuyere 1 occurs chiefly in the blow-back phenomenon of ejected gas, the burnout condition of the tuyere is estimated from the occurrence frequencies and intensity of intermittent impact noises and the blow-back phenomenon is suppressed by changing blowing conditions such as the blow-in flow rate, pressure and the like of the gaseous fluid.

Similarly, the sensor 14 is shifted to measure x2, y2...z2. And then, when dimensions on a drawing and standard cutting condition are  put into the computer 27, dimensions of the hatched section, which has not yet been  machined, are indicated on the display 28, and also an instruction is given indicating  amount of cutting, etc. and machining conditions. By operating it similarly after the  machining, dimensional accuracy check can be achieved. It is possible, by doing so, to  eliminate necessity of conducting marking operation.

Filed: 1983-03-11
Abstract: PURPOSE:To output an optical signal having high uniformity by switching a case when a testing optical signal is made to made to form an image on an image pickup device to be tested through a condensing lens and an image forming lens from a light emitting lamp, and a case when said signal does not pass through these lens systems. CONSTITUTION:A lens system 21 constituted of a condensing lens 14, a test chart 15 and an image forming lens is capable of moving mechanically to switch a case when it is inserted between a light emitting lamp 11 and an image pickup device to be tested, and a case when it is not inserted as shown in the figure. Accordingly, when uniform light is irradiated to the image pickup device to be tested, and the lens system 21 can be moved to shift from a signal path, therefore, uniform light required for the image pickup surface of the image pickup device to be tested is given by luminous flux having an extremely small solid angle, in the luminous flux emitted from the light emitting lamp 11, and the various characteristic tests of the image pickup device can be executed with high accuracy.

IPC: B60P1/16
Filed: 1983-03-15
Abstract: PURPOSE:To prevent a gasbag from slipping off due to its rapid expansion, by coupling the tip end edge of a short connecting rod with a side plate of the gasbag. CONSTITUTION:Base parts 13 and 14 of each of short connecting rods 11 and 12 are pivotally installed free of rotation in both of a projecting edge 8 extending over a top face 7 of a chassis 1 and another projecting edge 9 of a rear body 3 with pivots 15 and 16. Each of tip end edges 17 and 18 of these short connecting rods 11 and 12 is pivotally installed in position where they sould be, with a pivot 19 in which a base part 21 of a short setting rod 20 is pitotally installed, and a tip end edge 22 of the short connecting rod 20 is made to be connected to a side plate 23 of a gasbag 6. As a result, even if the gasbag is suddenly expanded large, the gasbag is prevented from slipping off owing to the short connecting rod and simultaneously these short connecting rods 11 and 12 come open with the rapid expansion of the gasbag centering on the pivot 19, thus no hindrance is brought to their linking.

Title: Call waiting system
Inventor: KAMIGAKI YOSHIZUMI
IPC: H04M3/42
Filed: 1984-03-05
Abstract: PURPOSE:To simplify processing stages of a switchboard of an exchange system with a call waiting function by allowing a terminal device to determine the start of the call waiting function initiatively. CONSTITUTION:When a terminal device C calls a terminal device A in communication, a timing circuit CP5 is actuated. When a call waiting request signal arrives before a timing circuit CP5 counts a specific time, a call waiting processing part CP1' performs call waiting processing. When an answer arrives from a terminal device A' before the specific time is elapsed, a central processor CP connects the call from the terminal device C to the terminal device A'. Therefore, an automatic switchboard needs not decide on whether the call waiting processing is preformed or not from subscriber data.

Filed: 1986-02-28
Abstract: PURPOSE:To enable the prevention of damage to a slide glass without controlling the deceleration of a motor, by providing a section for transmitting a driving force of a rotor to a linearly moving body through an engaging section of the rotor and an engaging section of the linearly moving body. CONSTITUTION:As a motor 10 rotates in a fixed direction, a disc 11 also turns in the direction of the arrow while a roller 12 moves depicting a circle starting from the position of O in the angle of rotation of the disc. As the roller 12 turns sliding in a slot 21 of an arm 7, the arm 7 makes an amplitude motion on a fulcrum shaft 8. On the other hand, since a roller 6 also is inserted into the slot 12 of the arm 7, it turns sliding therein according to the amplitude motion of the arm 7 and a slider 3 moves a shaft 4 to a guide 20. With further rotation of the motor 10 in the same direction, the arm 7 swings in the opposite direction, returns to the original position at O in the angle of rotation of the disc to stop and is hence restored as shown by the solid line of an ejector plate 2. As the motor 10 makes each turn, a storage box 16 moves downward by one pitch of a slide specimen 17 and the subsequent slide specimen 17 is carried out at the next cycle.
