IPC: B41J19/18
Filed: 1986-04-18
Abstract: PURPOSE:To facilitate the adjustment of a head gap, by a method wherein positioning openings provided to two plates of the mount part of a guide plate to a chasis are formed into slots and one or both of the slots are inclined with respect to the straight line connecting both slots. CONSTITUTION:A carriage 4 is engaged with a guide 10 at the opposite side part of a sheet feed roller 2 and supported so as to be guided by a guide shaft 3 and the guide plate 10. The guide plate 10 is attached to a chasis at two plates by rivets 11. The distance (head gap) between a head 5 and a platen 2 changes by the movement of the guide plate 10 in an up-and-down direction. Therefore, by changing the left and right positions of the guide plate 10 to the chasis 6, the height of the guide plate 10 to the chasis can be adjusted at an inclined slot parts. As a result, the degree of parellelization of the guide plate 10 to the platen 2 and the head gap G can be adjusted.

Abstract: PURPOSE:To shake off a liquid drop adhering into the inside surface of a bottle cover, and to elevate accuracy of an impact-inspecting machine, by giving impact to a bottle prior to its inspection, at the time of an impact-inspection for discriminating whether internal pressure of a closed bottle is suitable or not. CONSTITUTION:A pre-treatment conveyor device A makes an obstacle bar protrude from one side to a prescribed directly front position of an impact-inspecting machine being above a conveyor belt 3 stretched endlessly so that a closed bottle (alpha) freely passes through just under a probe 2 of the impact-inspecting 1. When the closed bottle (alpha) is passing trough, it is subjected to impact by the obstacle bar 4, and clears it, shaking its head. As a result, pre-treatment for shaking off or shaking down a liquid drop adhering into the inside surface of a bottle cover alpha1 of the closed bottle (alpha) is performed, and the bottle is made to pass through under the probe 2 of the impact inspecting machine 1 in a state that no liquid drop is adhering onto the bottle cover alpha1. In this way, at the time of an impact-inspection of the closed bottle (alpha), its internal pressure is discriminated exactly, and its measuring accuracy is elevated.

Title: Heat exchanger
Inventor: YAMADA TAKAO
IPC: F28F1/32
Filed: 1991-04-22
Abstract: PURPOSE:To enhance heat exchange efficiency by installing fins whose thickness direction is arranged to project along the flowing direction of gas in parallel and preventing a plurality of opening positions formed on each fin from lapping between each of adjacent fins. CONSTITUTION:With regard to fins 1 which adjoin each other, as an opening hole 1a is not lapped in the flow direction of a gas. The which has passed through the upper stream side fins 1 out of the adjacent fins 1, collides with an non-opening hole section of the downstream side fins 1 and changes its course. Therefore, the gas is unable to pass through the opening holes 1a straightly, which bends the flowing course and increases its length and forces the flow to be into a turbulent state or a similar state, thereby enhancing the efficiency of heat exchange. It is also possible to further enhance heat transfer performance by unifying the fins 1 by pipes 2.
