Title: Flame-retardant wire-covering composition
Inventor: SAWADA HIROTAKA
IPC: H01B3/44
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To obtain a wire-covering compsn. which is prevented from falling down during the burning test even if its oxygen index is not so high by compounding a wire-covering resin with a specified amt. of a disilicate. SOLUTION: This compsn. is prepd. by compounding 100 pts.wt. wire-covering resin with 20-70 pts.wt. disilicate. A conventionally used wire-covering resin can be used here; however, polyvinyl chloride or a polyolefin resin is pref. Examples of the disilicate are sodium disilicate. potassium disilicate, and calcium disilicate, sodium disilicate being the most suitable. The disiliate is a powder of which each particle is in the form of a balloon contg. water, and the water vaporizes by heat of combustion, foaming the compsn. Thus a wire-covering material made of the compsn. expands when burned, forming a strong shell and being prevented from falling down. If necessary the compsn. may further contain a flame retardant (e.g. antimony trioxide), a plasticizer (e.g. dioctyl phthalate), etc.

Filed: 1994-05-10
Abstract: PURPOSE:To remove interference of electromagnetic wave caused by an electric compressor drive device by using a core wire side of a shield wire as power supply wire and electric compressor drive wire and ground connecting a shield side to an equipment including an electric compressor drive device. CONSTITUTION:A power supply electric wire 2 and a motor electric wire 5 are used as a shield wire, and its shield side is connected to an electric compressor drive device 3 which is grounded on a car body earth 7 via a capacitor 6. A core wire side of the power supply electric wire 2 is insulated from the car body earth 7 by the capacitor 6 as regards to direct current. Consequently, even if the core wire side of the shield wire is electrically connected to the shield side, one does not get an electric shock even if he/she touches a terminal of a battery 1 at the time of inspection, etc. Also, even if high frequency current flows on the core wire side of the power supply electric wire 2 and the motor electric wire 5 and electromagnetic wave having frequency of 1MHz is generated, impedance of the capacitor 6 is small. Consequently, the shield side is almost grounded on the car body earth 7 with respect to high frequency, resulting in shield effect.

Abstract: PURPOSE:To prevent the accidents of short circuits due to the damages of metallic sheets by making length in the direction of stacking of duct pieces longer than that in the same direction of the metallic sheets. CONSTITUTION:A plurality of duct pieces 21a are incorporated into high-tension windings 4, and a cooling duct 21 is formed by the pieces 21a. Since length in the direction of the stacking of the windings of the pieces 21a is set to size larger than that in the direction of the stacking of metallic sheets 3 constituting the windings, the upper and lower end sections of the pieces 21a are brought to the state in which they are projected from the upper and lower end sections of the sheets 3. The length of the pieces 21a is formed in size shorter than the end sections of insulating sheets 4 projecting from the end sections of the sheets 3, and considered so that thermal resistance at the end sections of the duct 21 does not increase. Accordingly, the corner sections of the pieces 21a do not damage the sheets 3 on the winding work, etc. of the sheets 3.

Abstract: PURPOSE: To detect definitely a small load on a pressure body by using a piezoelectric element, which generates a trigger signal on detecting a smaple touching the presure body, etc.  
     CONSTITUTION: On detecting pressure body 8b coming in contact with smaple 10, piezoelectric element 9 develops a voltage which rises suddenly. Trigger generator 21 compares the signal of the voltage with the set voltage of the comparator, so that when the above-mentioned signal is higher than the set voltage, a high-level trigger output signal will be sent out. This trigger generator 21 is connected to the input terminal of gate circuit 22, whose other input terminal connects to comparator 19; when high-level signals are simultaneously applied to two input terminals of this gate circuit 22, a low level output signal is outputted. On receiving the signal from above-mentioned gate circuit 22, operator 18 starts arithmetic. In this way, a small load on pressure body 8b can difinitely be detected.
