Penelitian ini membahas tentang Perancangan Cetakan Injeksi Plastik Two Plate (Slider with Reciprocating Lifter) untuk Produk Battery Cover Syringe Pump. Pump memiliki bentukan slider pada bagian bawah dan lifter dalam snap join atas yang harus melakukan perhitungan agar dapat memastikan apakah diejeksi dengan paksa atau menambah konstruksi menggunakan (reciprocating) produk tidak mengalami ker...

This paper analyzes some basic design aspects for a three phase diamagnetic levitating rotor. A proposed design uses a triangular configuration of magnets for a levitating rotor. A formula for finding a the approximate levitation point of the rotor is given. The proposed system uses three phase alternating current and a nine coil configuration to drive the levitating rotor. For this configurati...

Proses pengangkatan tandan buah segar kelapa sawit ke truk secara umum masih dilakukan manual, dengan beban kerja berat dan berpotensi cedera. Adapun peralatan pengangkat yang sudah ada bertenaga motor bakar biaya tinggi. Tujuan dari penelitian ini adalah merancang menguji alat dalam bak memanfaatkan bobot truk. Bobot pada roda belakang ketika mundur dimanfaatkan untuk menekan sepasang silinder...

During the course of a double murder trial, it became apparent that the two adhesive lifters from the two cadavers had been mislabeled before being presented in court. The question was raised whether DNA testing from the biological material remaining attached to the lifters could resolve this mix-up. In fatal shooting cases where a bullet has been fired through a body surface, an adhesive lifte...

This paper shows in detail the construction and operation of an apparatus that levitates when submitted to voltages greater or of the order of 20 kV. This device, which basically corresponds to an asymmetric capacitor, is commonly known in the literature by the name ‘lifter ’. It also will be shown in this article, through rather simplified calculations, that the physics grounds of the observed...

A new instrument that aids in retreating or revising lamellar refractive surgery is described. The edge delineator and lifter can both delineate and lift the edge of a previously made corneal flap.
