Title: Thermosetting powder composition based on polyester and acrylic copolymer
Inventor: RIYUTSUKU MOAN
IPC: C08L63/00
Filed: 1994-03-10
Abstract: Powdered thermosetting compositions including (a) a specific polyester containing carboxyl end groups and (b) an acrylic copolymer containing glycidyl groups. The polyester (a) containing carboxyl end groups has an acid value of 15 to 70 mg of KOH/g and is necessarily prepared in two stages. In the first stage a polyester containing hydroxyl end groups is prepared from at least one polycarboxylic acid other than 1,4-cyclohexanedicarboxylic acid and from at least one aliphatic or cycloaliphatic polyol and, in the second stage, the polyester containing hydroxyl end groups thus obtained is esterified with 1,4-cyclohexanedicarboxylic acid alone. Moreover, the composition of the polyester (a) is highly specific: it contains at least 75 mol% of terephthalic acid, at least 10 mol% of 1,4-cyclohexanedicarboxylic acid and not more than 14 mol% of at least one other aromatic and/or aliphatic and/or cycloaliphatic polycarboxylic acid, relative to the total of the carboxylic acids forming part of its composition. The powdered thermosetting compositions obtained from polyester (a) and from the acrylic copolymer (b) are particularly useful for the preparation of powdered paints and varnishes. They yield coatings exhibiting high gloss, excellent mechanical properties and, at the same time, good weathering resistance.

Title: Magnetic disk
Inventor: MIYAKE AKIRA
IPC: G11B5/70
Filed: 1997-02-08
Abstract: PROBLEM TO BE SOLVED: To improve durability and to make high-density recording possible by specifying the thickness of a magnetic layer to a specific value range and disposing an under coating layer having a thickness including conductive powder and oleyl oleate above the thickness of the magnetic layer between the magnetic layer and a substrate. SOLUTION: The thickness of the magnetic layer formed via the under coating layer on the substrate is specified to >=0.3 to <=0.5μm, by which the high- density recording is made possible. The under coating layer disposed between the substrate and the magnetic layer is made thicker than in the magnetic layer to incorporate a sufficient amt. of the conductive powder and the oleyl oleate into this layer and to make the surface electric resistance of the magnetic layer sufficiently low. The oleyl oleate in the under coating layer and magnetic layer of the magnetic disk rotating at a high speed is made easily movable in the under coating layer as a passage along centrifugal force, by which the oleyl oleate is sufficiently oozed in the position where the magnetic head slides. As a result, the wear resistance and durability are improved.

Title: Fixing device
Inventor: SONE KIYOSHI
IPC: G03G15/20
Filed: 1979-04-03
Abstract: PURPOSE: To enhance fixing strength and reduce addition elements by preheating recording paper through induction heating and performing flash fixing.  
     CONSTITUTION: NESA glass 12 coated with a tin oxide thin film 12a is disposed at the opening of the reflecting plate 11 covering a flash discharge tube 1 and a guide plate 13 being a counter electrode is disposed in opposition to this and is grounded. The thin film 12a of the fixing part constituted in this way is connected to the plus end of a high-voltage capacitor 3 and the guide plate 13 to the minus end. As a result of this, at the time when the capacitor 3 is being charged, the full-wave rectified wave of the output high-frequency high voltage of a high-frequency inverter is applied between the thin film 12a and guide plate 13, whereby the dielectric evolution of heat is caused in the recording paper 15. Since the recording paper 15 itself evolves heat in this way, the toners assuming a molten state by absorbing the flash light of the discharge tube 1 fit well to the recording paper 15, thereby accomplishing good fixing. Even more, the inverter being the power source for the flash discharge tube is used commonly for a dielectric heating power source and therefore addition elements become less.

Filed: 1979-04-04
Abstract: PURPOSE: To perform I/O control of multiprocessors with a simple circuit constitution, by providing a register, which stores the channel number of a CPU each time the I/O instruction from plural CPUs is accepted, in every I/O device.  
     CONSTITUTION: CPU2 reads out the value of the register in RAM14 assigned for an I/O device; and if its contents are the channel number of CPU2 itself and CPU2 needs to instruct the I/O device, CPU2 issues an instruction to the I/O device. The I/O device after use interrupts CPU2 of the storage channel number of register 5 for itself. Then, the value of register 5 is rewritten for the channel number of another CPU2. Meanwhile, if CPU2 need not issue an instruction to the I/O device, the value of register 5 is rewritten for the channel of another CPU3. When CPU2 reads out contents of register 5 and its contents indicate another channel number, instructions to the I/O device are inhibited, and it is unnecessary to rewrite contents of register 5.
