Title: Photosensitive resin composition
Inventor: AZUMA KAZUFUMI
IPC: C08F290/00
Filed: 1983-04-15
Abstract: PURPOSE:To improve the curing shrinkability, adhesive strength and heat deteriorating property by adding a specified compound and a photosensitizer as essential components. CONSTITUTION:This photosensitive resin composition contains a compound represented by formula I and a photosensitizer as essential components. The compound has a group represented by formula II or III as R in the formula I . For example, the compound is prepd. by diolating an epoxy compound obtained from epichlorohydrin and bisphenol A, modifying it to acetal, and forming 2-methylene-1,3-dioxoran rings represented by the formula II at both terminals. The photosensitive resin composition obtd. by adding the photosensitizer and other additives to the prepd. addition polymerizable monomer has a low coefft. of curing shrinkage and high adhesive strength to a substrate, so it shows superior properties when used as a photosensitive adhesive or a photosensitive coating material. Since the composition has radical polymerizability, heating is not essentially required, so any ionic substance is not introduced into the material, and heat deterioration is not caused. The composition is very useful as an adhesive or to manufacture a composite material.

Title: Peeling-off of adherend bonded with adhesive
Inventor: MATSUI SHIGEO
IPC: C09J5/00
Filed: 1984-04-04
Abstract: PURPOSE:To peel off an adhesive-bonded adherend in a short time without causing damage to it, by heating a bonded material under pressure in a closed vessel and evacuating the vessel after the bonding strength of the adhesive is lowered. CONSTITUTION:A bonded material 4 is placed on a rack 3 in a closed vessel 1 which contains water 2 and the container is covered with a lid 5. When heated with a heater 6, a part of water 2 is vaporized and an upper space 7 in the vessel is filled with water vapor. As a valve 8 is opened, air and water are discharged from the vessel and only water vapor remains in the space 7. Closing of the valve 8 after discharge of a required amt. of air causes an increase in pressure in the vessel 1. When predetermined temp. and pressure have been reached, the vessel is kept as it is for predetermined hours so that water may penetrate into the adhesive through micropores leading to lowering of strength of the adhesive. When the valve 8 is opened, pressure in the vessel is decreased and pressure in the adhesive increased by heating and pressurization destroys an interface between adhesive and adherend, causing peeling-off of the adherend.

Filed: 1991-03-29
Abstract: PURPOSE:To acquire image information on a subject which changes by time even with an image input device of high image resolution by switching the image reading mode between the moving and non-moving states of a solid state image pickup element. CONSTITUTION:When an image input device is used for input of the image data of high image resolution, a high image resolution mode is selected by a switch 12 for the photographing mode. When an image is fetched, the position of a solid state image pickup element 26 is finely moved by a piezoelectric element 253. Each image information is inputted to an A/D converter 28 via a preprocessing circuit 27 and converted into the digital signals. These digital signals are stored in a buffer memory included in a signal processing circuit 31. Then the image information is read out by the prescribed frequency and the element 26 is repetitively moved. Thus a necessary number of sheets of image information are stored in the buffer memory. Then the data are read out of the buffer memory and processed by the circuit 31. Thus the image signals are recorded on a memory card as the data of high image resolution.

When each recording head unit 21 travels acceleratedly, pressure of ink in the feed pipe 12 connecting between each recording head unit 21 and an ink container 20 fluctuates. This fluctuation in pressure is buffered by absorption by fluctuation in volume due to displacement of the diaphragm 3 of space 4. Then, fluctuation in pressure is not transmitted to a jetting nozzle of the recording head, and normal ink jet from the nozzle is maintained.

IPC: G11B5/64
Filed: 1985-03-29
Abstract: PURPOSE:To form a carbon protective film having highly uniform film thickness and high strength by forming a metallic magnetic thin film on a substrate and then vapor-depositing a carbon protective film on the metallic magnetic thin film with use of an accelerated electron having >=5KeV energy. CONSTITUTION:The continuous film of a ferromagnetic metal is provided on a disc substrate as the magnetic layer and a carbon protective film is formed on the metallic magnetic film by vacuum deposition using electron-beam heating. An accelerated electron having >=5KeV is used as the electron beam in the vapor deposition.

Besides, the energy of the accelerated electron is closely related to the vaporization rate of carbon. Especially, when the vaporization rate is designated as R and the pressure in vaporization as P, more uniform film is formed as the P/R value decreases.
