Title: Photoelectric tube detecting mark
IPC: G01B11/00
Filed: 1992-03-17
Abstract: PURPOSE:To make the contrast with a base color at the time of positioning clearer, and make the color to be the same as the base color after heating by constituting the title mark, which positions the surface pattern of a liquid filling container, of a thermal discoloring ink which presents a specified tone at a normal temperature and changes irreversibly into a tone by heating at a specified temperature. CONSTITUTION:For example, on the surface of a plastic tube 1 made of a pink low density polyethylene, a printed image 3 of patterns or characters, etc., is formed, and at the same time, at the upper end of the tube 1, a black green photoelectric tube detecting mark 5 is printed by a thermal discoloring ink made of a mixture of NiCO3 and CdS. At the time of positioning of the tube 1, in which a content has been filled, the mark 5 presents a black green color, and the contrast to the base color of the tube 1 is clear, and the detection can be easily done by a photoelectric tube. Then, the upper end opening of the tube 1 is attached to a fixing plate 6, and when the tube 1 is heated and fused, the mark 5 is irresversibly discolored into pink by this heating, and becomes the same color with the base color, and the mark 5 vanishes.

Title: Packaging material capable of being heated with microwave oven
Inventor: KOBAYASHI YOSHIHIRO
IPC: B65D81/34
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To make effectively and surely a narrow through-hole for the removal of gas such as vapor without causing a container to burst even when the whole container is put and heated in a microwave, by making a cut or notch for the guiding of the narrow gas-removal through-hole into a layer outside a face coated with a releasing agent. SOLUTION: A cut or notch is made in an external layer, which is to be coated with a releasing agent, in advance so that when the entire container is put and heated in a microwave oven to eat food later and then internal pressure is applied due to a temperature increase, a narrow hole for the removal of gas such as vapor is made in the seal face of a frozen food/chilled food container made of a laminate plastic film in which an external layer comprises a heat-resistant, thermoplastic resin film, an internal layer comprises a sealant, and an intermediate layer has a releasing-agent layer on its seal formation face. It is preferable that the cut or notch be made in the seal faces of the openings in a front end and rear end rather than in a back-lining seal part because dummy bursting is prevented.

Inventor: MITSUIDA MASATOSHI
IPC: F16K11/10
Filed: 1978-08-01
Abstract: PURPOSE: To provide a four-way electromagnetic valve, in which three spools are used in a set for enabling to stop supply of air at an intermediate position of the stroke, whereby it is enabled to lower consumption of air and to save energy for operating the system.  
     CONSTITUTION: The electromagnetic valve of this invention comprises a set of three spools, i,e., a right outer spool 2, left outer spool 2' and middle spool 3. Here, if right-side solenoid is energized, right outer spool 2 is pushed and shifted to the left by the solenoid. Resultantly, middle spool 3 is pushed and shifted also to the left by the spool 2, and it is self-maintained at the position by left-side permanent magnet 4'. Therefore, air is supplied through the passage from IN to OUT1 shown in the drawing, whereas it is exhausted from OUT2 to EXH. If the right-side solenoid is de- energized at an intermediate position of the stroke, spool 2 is shifted to the right by the force of right-side spring 5 and interrupt communication between IN and OUT1. Thus, supply of air is interrupted while keeping continuous exhausting of air. Therefore, it is enabled to reduce consumption of air and to save energy for operating the system.
