Title: Resin made chain
Inventor: KASAI KENJI
IPC: C08L79/08
Filed: 1995-09-25
Abstract: PURPOSE: To provide a resin made chain causing few wear and a satisfactory sliding property in a chain trained over at least two sprockets by forming the links of the chain of a component of material consisting of polyamide-imide resin and fluororesin. CONSTITUTION: Since polyamide-imide resin has an excellent antiwear property, it provides a chain having the longer life, compared with prior resin chain made of polyether-imide resin and polyoxymethylene resin. Also, since the polyamide-imide resin has an excellent creep resisting property, it does neither lengthen the chain like existing resin, nor need the adjustment of the slack of the chain, so that the maintenance-free chain is obtained. Further, by combining the polyamide-imide resin with fluororesin, the advantage of the polyamide- imide resin is utilized while a resin chain improving the sliding property without damaging conveyed articles to provide the satisfactory slip property and few wear of link itself of the chain is obtained.

Abstract: PROBLEM TO BE SOLVED: To simply and surely obtain an aggregate having specified or lower dry specific gravity by classifying coal ash to obtain a coarse powder having a specified or smaller proportion of fine particles having a specified or smaller particle size, and granulating and calcining the coarse powder. SOLUTION: Coal ash is classified to obtain a coarse powder which contains fine particles of <=10 μm particle size by <=15 wt.%. The coarse powder is granulated and calcined to obtain a lightweight aggregate having <=1.25 dry specific gravity.

In this case, the agent of low specific gravity is added and mixed by <=40 pts.wt. to 100 pts.wt. of the coarse powder, and the mixture is granulated and calcined. Instead of the agent of low specific gravity or with addition of the agent, a foaming agent can be mixed. The foaming agent is added by <=20 pts.wt. to 100 pts.wt. of the coarse powder or the sum of the coarse powder and the agent of low specific gravity. As for the agent of low specific gravity, ash from a fluidized bed boiler is used, and as for the foaming agent, perlite is used.

Abstract: PURPOSE:To reduce the OH groups remaining in a core and to improve the adsorption loss characteristic by depositing a clad soot on a porous core soot by VAD method through the rare-earth element treatment by an alcoholic soln. and then sintering the deposited soot. CONSTITUTION:The porous core soot prepared by VAD method is impregnated with an alcoholic soln. contg. rare-earth elements. The impregnated soot is then dried to vaporize alcohol, and then a clad soot is directly deposited on the core soot. The material is dehydrated and then sintered to vitrify the core soot and clad soot, and the desired optical fiber preform is obtained. Since the clad soot is directly deposited on the core soot and both soots are dehydrated, the soots are sufficiently dehydrated. Accordingly, the OH groups remaining in the core are drastically reduced, and an optical fiber doped with the rare- earth elements and with the adsorption loss characteristic improved is obtained.

IPC: F01N9/00
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of abnormality such as contact welding, etc., of a power supply changeover switch. SOLUTION: A battery 11 and a catalyst converter (EHC) 21 fitted with an electric heater are connected to a generator 3 through a changeover switch 25, and a changeover switch 25 is switched over to the side of EHC 21 at start of an engine 1 so as to supply EHC 21 with power directly from a generator 3.

Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To judge the life of a battery by making the difference between the stable battery voltage Vb1 and the stable battery voltage Vb2 obtained in continuously discharging a battery by a current value I2 smaller than current I1 to a specified value or more. SOLUTION: The behavior of the battery voltage and a current value, obtained when a battery 2 whose discharging time is 7 minutes and a battery 15 whose discharging time is three minutes are respectively discharged at a current value of 19.5A for ten seconds and then continuously discharged at a current value of 1.625A for ten seconds are indicated in the graph. When discharge is started at a current value of 19.5A, the battery voltage is lowered and indicates a stable value. At this time, the voltage of the battery 15 having large deterioration is once largely lowered and restored after indicating a minimum value. After that, the current value is increased to 1.625A, the voltage is increased. The battery 15 having developed deterioration indicates a lower value in comparison with the battery 2 in comparison by the voltage Vb1 obtained after charge is performed for ten seconds.  When the value difference between the battery voltages Vb2 and Vb1 is 1.7V, it is judged that the battery has had it.

Abstract: PROBLEM TO BE SOLVED: To break current surely, and discharge inside gas outward so as to prevent the explosion of an armor can when the internal pressure of a battery rises by fitting a cleavable shutoff valve between a safety valve and a sealing plate. SOLUTION: The thin-thickness portions of a safety valve 9 and a shutoff valve 15 are made to be easily cloven when gas is generated resulting from the disorder of a power generating element 3 so that the internal pressure rises rapidly.

Title: Device for eliminating wire-propagated noise for vehicles
Inventor: TODA MASAAKI
IPC: H01B7/00
Filed: 1987-10-02
Abstract: PURPOSE:To prevent generation of noise adversely affecting to electronic equipments for vehicles, by connecting a noise suppressing line consisting a pair of line wound spirally on a core, with a power supply line of an electric noise source. CONSTITUTION:A noise suppressing line (h) consisting of a pair of lines (g), (g') wound spirally on a core (f) is connected to a power supply line (b) of an electrical noise source (e.g. electric fuel pump) (a). In the noise suppressing line (h), current flows alternately to opposite directions in view of the cross section of a coil unit U constituted by the pair lines (g), (g'). Accordingly, magnetic fluxes H, H' generated in the coil flow always in opposite directions and act to cancel with each other. Therefore, no electromagnetic wave is leaked out of the device. Electromagnetic radiation from the noise suppressing line (h) is thus eliminated completely, and there is no disturbance to electronic equipments such as generation of radio noise or erroneous operation.
