PURPOSE:To control easily an initial position of a trackless trolley car by running the trackless trolley car at a low speed and at a wheel angle of zero, when a power source is turned on, and setting its position data, when an initial position detecting object on a running path is detected. CONSTITUTION:When a start switch 10 of a trackless trolley car which is at a standstill at this side of plu...

Unsaturated polyester resin foams or cellular structures of varying low densities are prepared quickly at ambient temperatures from an admixture which comprises a liquid unsaturated curable polyester resin, an organic isocyanate compound, a suitable surfactant, an accelerator and a particular combination of peroxide curing agents, which also serves to initiate the release of gases that permit expa...

The invention provides a novel composition useful as a heat-resistant coating material for a metal or ceramic article surface. Also, the novel composition is useful as an adhesive agent for bonding metal articles, ceramic articles or articles of a metal and a ceramic. The adhesive strength of the composition is so strong that no peeling takes place even after many times of repeated cycles of rapid...

The invention relates to a self-locked differential which is composed of a casing 7 forming the hub of a ring gear 8 for driving the casing about an axis 5 common to two half-shafts 3, 4. It is characterised in that it comprises two worms 10, 11 whose threads are in the same direction and of the same pitch engaging with one another on two parallel spindles 14, 15 orthogonal to the axis of the half...

PURPOSE:To obtain a composition having remarkably increased melt viscosity and excellent moldability, without lowering the characteristics of the base resin, by compounding a polyether ester amide with an aromatic linear polyester. CONSTITUTION:The objective composition can be prepared by compounding (A) 50-99pts.wt. of a polyether ester amide derived from (i) a >=6C aminocarboxylic acid, (ii) a l...

PURPOSE:To reduce corrosion of aluminum wiring for the entire part of device by providing a ring-shaped aluminum or aluminum alloy film surrounding the leadout electrodes on the covering protecting film on the substrate and then sealing it with resin. CONSTITUTION:An oxide film 2 is formed on a silicon substrate 1 and an aluminum electrode pad 4 and element coupling aluminum wiring 3 are provided ...

PURPOSE:To measure properly the vibration characteristic of a magnetic head by giving the vibration in the state where the head is floating, detecting an interference fringe on the floating surface and converting it into a signal. CONSTITUTION:The air flow caused by the rotation of a disk 1 floats a magnetic head 2, which vibrates by driving an actuator 4 by means of an excitation device 5. With r...
