Title: Deciding device for line number of hot-line cable run
Inventor: TANIDA TOMOICHIRO
IPC: G01R31/02
Filed: 1986-12-26
Abstract: PURPOSE:To decide the correspondence relation of a cable run in a hot-line state by inputting an in-phase detection signal by the transmitting means of an input-side cable run connected to the secondary coil of a transformer and finding at which one the signal appears. CONSTITUTION:A transmitter 10 is equipped with a sender which sends out an C signal of, for example, 1MHz and a pair of output terminals which output the AC signals as the in-phase detection signal to the input-side cable run. A receiver 20, on the other hand, is equipped with a band-pass filter of 1MHz which passes a detection signal inputted from an input terminal, an amplifier, a rectifying circuit, and a voltmeter as a detecting and displaying device. When the correspondence relation between input-side cable runs 2 and 3 and output- side cable runs 6 and 7 is decided, in-phase detection signals i1 and i2 are sent from the output terminals of the transmitter 10 to the input-side cable run 2 connected to, for example, terminals of the secondary coil L2 of the transformer TR1. The signals i1 and i2 are in phase with each other, so they cancel each other at the secondary coil L2 of the transformer TR1 and never appears at the primary coil L1. The signals of the cable runs 6 and 7 are checked to decide the output-side cable runs of the cable run 2.

Title: Radiation panel
Inventor: IMAIDA TAKESHI
IPC: F24F1/00
Filed: 1987-12-10
Abstract: PURPOSE:To prevent condensed water from being dripped into a room by a method wherein a radiation plate connected to a tube in a heat exchangeable manner where coolant or thermal medium flows and having a function to guide the condensed water at the surface to a rear surface and a thermal insulation material arranged along with the rear surface and having its rear surface exposed in a surrounding atmosphere and open cells. CONSTITUTION:When a cooling operation is carried out, cooled coolant may flow through a tube 2. In this case, a cold heat from the tube 2 is transmitted directly or via a heat conducting plate 6 to a radiation plate 3 to cause it to be cooled. Then, indoor air around it, occupants and objects are cooled from the surface of the radiation plate 3. When the surface of the radiation plate 3 is cooled down lower than a dew point of the indoor air, moisture contained in the indoor air is dewed on the surface. This dew permeates into the radiation plate 3 composed of porous metallic substance, it may not form any large-sized particles, so that the dew water does not drop into the room and does not stain the interior. Moisture content which has permeated into the radiation plate 3 is moved through a capilary action within the radiation plate 3, evaporated at the rear surface and dispersed into the surrounding atmosphere.

A hurdle-shaped structure 15 which comprises a plurality of circular-shaped gratings 16 in its cross section is laid out in a region in the lower part of the gas cooling section 13 in such a manner it may cross the gas flow passage 14. As a result, a bottle-neck section 17 is formed in the gas flow passage 14 between the gratings 16 and the grating 16 and the inner wall surface of the gas cooling section 13. The gratings 16 are covered with a refractory material 18 while a refrigerant passage 19 is formed inside so that the refrigerant may flow. This construction makes it possible to inhibit cold radiation to the combustion chamber 12 of the furnace body section 11 from the gas flow passage 14 and prevent the cold air from being engulfed into the furnace body 11.

Abstract: PROBLEM TO BE SOLVED: To surely cut a film at a perforation part when an automatic packaging is performed by a method wherein a heat-shrinkable film having a resin layer comprising at least one of a polyethylene-based resin and a polypropylene- based resin, and having a specified rate of shrinkage, is used. SOLUTION: This heat-shrinkable film may satisfy 40>=A-B>=5 when it is taken that a temperature at which the increase amount of a rate of shrinkage in the vertical direction becomes a maximum is A deg.C, and a temperature at which the increase amount of a rate of shrinkage in the lateral direction becomes a maximum is B deg.C, and in order to make the film be cut by itself at a perforation part, a film of which the shrinkage stress in the vertical direction is 5 kgf/cm<2> or higher is preferable. Then, as the composition, the film has a layer comprising at least one of a polyethylene-based resin and a polypropylene-based resin.  Then, when the film greatly shrinks in the lateral direction, an engaging part 21 is formed between batteries at both ends and the film, and for this reason, when the film greatly shrinks in the vertical direction, the shrinkage in the vertical direction does not advance.

Filed: 1987-12-11
Abstract: PURPOSE:To previously preclude a dielectric breakdown accident by inspecting the electrostatic capacity of the insulating layer of a rotating machine coil and detecting remaining dielectric strength from the quantity C''/C' of variation in electrostatic capacity C'' measured by using a couple of measured frequencies to the electrostatic capacity C'. CONSTITUTION:The insulating layer 2b of the high-voltage rotating machine coil 2 is formed of mica and resin. In this state, the electrostatic capacity of the insulating layer 2b between a conductor 2a and a model slot 1 is measured to obtain a constant value shown by a prescribed expression. Here, when the high-voltage rotating machine is used for a long time, composite stress is applied to the insulating layer 2b, a void and a cavity part 3 for control, etc., are produced between mica tapes in the insulating layer 2b and the conductor 2a and insulating layer 2b. The specific dielectric constant epsilon' of this cavity part 3 is nearly 1, so the electrostatic capacity of the insulating layer 2b at the time of deterioration is different from the value in the initial state. The deterioration like this causes the insulating layer 2b to decrease in dielectric strength and makes it difficult to absorb moisture.

SOLUTION: Distance between the center of a bump electrode arranged on the outermost circumference of a semiconductor chip to the end face thereof is determined to satisfy formula I ; sinh(√A.(X-D/2))/cosh(√A.L)<=0.3, where D is the diameter of bump electrode, L is the distance from the center of semiconductor chip to the end face thereof, A is a variable represented by formula II; A=(G/hR).(1/E1 .h1 +1/E2 -h2 ). In formula II, G is modulus of rigidity of sealing resin, hR is the thickness of sealing resin, h1 , h2 are the thickness of semiconductor element and circuit board, E1 , E2 are Young's modulus of semiconductor element and circuit board. Since the shearing strain of sealing resin decreases as approaching the center of semiconductor chip, shearing deformation of bump can be reduced significantly resulting in a semiconductor device having highly reliable bump joint.
