Japan developed a cutting wireless charging diaphragm
Researchers at the University of Tokyo in Japan have developed a tailor-made wireless charging film that can be cut into various sizes and "sticked" to the surface of objects such as clothes pockets, bags, tables, etc. to charge electronic devices such as mobile phones.
The University of Tokyo research team recently introduced on the school's official website that existing wireless charging products usually design and install charging coil arrays according to the shape of specific products, but once they are partially cut off, they may lose their charging capacity, and the wireless charging diaphragm they developed is tailored. It can also be charged later.
The wireless charging diaphragm uses a special H-type internal coil array, and a power supply is arranged in the diaphragm. The peripheral edge of the diaphragm can be cut, and the remaining coils maintain charging capability.
In the experiment, the researchers made a wireless charging diaphragm weighing about 82 grams on a flexible substrate of about 40 cm in length and width, with a maximum charging power of about 5 watts. The research team expects this technology to be applied to the pocket of the garment, the inside of the bag, the table or the box, giving some everyday items a wireless charging function.
STABLE AT LOW SPEED
Closed-loop control pressure and flow, at low pressure and low flow operation performance is particularly outstanding, shoot rubber speed in less than 1 mm/sec without crawing,pluse,high stability. System according to the actual product process requirements, set arbitrary pressure and flow, avoid excess heat generation, the oil temperature relative to the traditional injection molding machines is stable. In addition, the pressure stability of the pressure and flow rate, high control accuracy and repeat precision.
MACHINE SERVICE LIFE LONGER AND CLEANER WORKING ENVIRONMENT
Less noise emissioins
The noise of th hydraulic system control within the scope of the national standard.
Low heat and cooling energy demand is low, more suitable for production environment with air conditioning.
