Title: Ink jet printer and maintenance method thereof
Inventor: SUZUKI YUTO
IPC: B41J2/01
Filed: 2018-09-21
Abstract: To provide an ink jet printer and a maintenance method thereof capable of suppressing an increase of the size of the device, supplying a maintenance liquid instead of ink to a plurality of heads, and reducing the consumption amount of the ink and the maintenance liquid.SOLUTION: The ink jet printer has maintenance liquid supplying mechanism 30. When a three-way valve provided on an ink pipe is switched, a maintenance tank 85 supplies a maintenance liquid to each head via a maintenance pipe 32. The maintenance pipe 32 is connected to the ink pipe downstream of an intermediate tank. Thus, ink in the intermediate tank needs not to be replaced by a maintenance liquid when the maintenance liquid is supplied. As a result, the consumption amount of the ink and the maintenance liquid can be reduced.SELECTED DRAWING: Figure 2

Title: Vehicle bodywork and method of constructing vehicle
Inventor: MARK ANDREW JONES
IPC: F16B11/00
Filed: 2018-10-04
Abstract: To provide a vehicle with one or more integration panels lying between a tubular framework and exterior body panels.SOLUTION: A laser-cut and spot-welded tubular frame chassis typically has accuracy of ±1.5 mm. This invention proposes that a vehicle comprise one or more integration panels lying between a tubular framework and exterior body panels. These can be made of a lightweight material, and can be made to be structural or non-structural depending on the intended use and location of the panel. It can also be attached adhesively to the framework at an early stage of manufacture. The exterior body panels can then be attached to the integration panels in any preferred manner, such as adhesives, bolts, clips or the like. This attachment is preferably non-adhesive, and can therefore be done at a late stage in manufacture after much of the interior work has been done.SELECTED DRAWING: Figure 1
