Title: Container and shoulder cover thereof
Inventor: HATSUTORI YUKIYORI
IPC: B65D83/14
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To easily disassemble a resin part and a metallic part and facilitate removing from a container body in particular, by making separable a part of the circular wall and making discontinuous the circular wall at the separated state. SOLUTION: A nozzle is separated from a container body 1 at first, prior to removing of a shoulder cover 2. Thereafter, a separable piece held by breaking lines 11a, 11b is separated from the shoulder cover 2. In this time, a finger is hooked on the upper end of the separable piece and the piece is erected so as to be easily picked up. And the separable piece is peeled off from the shoulder cover 2 by picking the part with fingers. Thereby, the shoulder cover 2 is deformed to be a nearly C-shaped discontinuous member. Then, a force to the reverse direction is applied to two ends of the shoulder cover 2, formed by removing the separable piece to separate the shoulder cover 2 from the container body 1.  In this way, since the shoulder cover 2 can be removed from the container body with empty hands, the resin part and the metallic part can be easily separated from each other and hence, the recycling efficiency is increased.

Filed: 1989-09-22
Abstract: PURPOSE: To form a hard copy image accurately estimated at a correct position by making a web position and a position of a laser beam on a scanning line synchronize each other. CONSTITUTION: The information of an image area position is effectively given by a photodetector 46 to an electronic circuit, and when the image area is adjacent to the scanning line 48, a page starting(SOP) signal is generated, and when a line starting(SOL) signal is received by the detection of the laser beam by the photodetector 50, the modulation for the laser beam can be started by an electronic control circuit part. Then, the synchronized transfer of a sheet and a photoconductive face 14 is delayed during a period depending on the timing of the SOP signal and the SOL signal, related with the position of the beam along the scanning line 48 when the SOP signal is emitted. Thus, accurate estimated positioning is attained.
