Title: Formation of contact pin connecting pattern
Inventor: MURAKAMI SATORU
IPC: H05K3/40
Filed: 1987-10-15
Abstract: PURPOSE:To make the bonding strengths of contact pins against a thermal resistant insulating substrate uniform by providing a dummy land along the peripheral of a land which is to be connected to an electronic device component. CONSTITUTION:To make the adhesive strength of a contact pin peripherally located in a predetermined region against a thermal resistant insulating substrate 10 to be identical with that of a contact pin internally located, the amount of silver (Ag) soldering material to be introduced to a connecting land must be kept at a predetermined level irrespective of its location in the predetermined region. In other words, a dummy 11' to serve as a connecting land is formed outside the predetermined formed region. In this case, the amount of the silver (Ag) soldering material to be introduced to the land which will become the dummy 11' depends on the size of a seat consisting of the silver (Ag) soldering material which will be used for coating, but the amount of silver (Ag) soldering material to be introduced to the connecting land in the peripheral of the predetermined region becomes equal to that to be introduced to the land located inside such region. This allows the adhesive strengths of the contact pins within the predetermined region to be uniform.

Title: Device for limiting progress of layer short circuit of coil
Inventor: NABESHIMA SUSUMU
IPC: H01F27/28
Filed: 1988-10-14
Abstract: PURPOSE:To delay the progress of layer short circuit until the operating time of a thermal protector by inserting inter-layer insulating paper into coil layers at every plurality of layers. CONSTITUTION:Inter-layer insulating paper 7 is inserted into layers of a coil 2 at every three layers. The inter-layer paper 7 is usually inserted at every 4-5 layers when the coil has a small capacity and at every two layers when the coil has a large capacity, but the inserting interval of the paper 7 is empirically decided. Since the insulating paper 7 is inserted at every plurality of layers of the coil 2, progress of layer short circuit can be suppressed when the layer short circuit occurs in layers of the coil 2. Therefore, the progress of the layer short circuit can be delayed until the operating time of a thermal protector 3 and emission of smoke can be suppressed.

Title: Pouring trough material
Inventor: SATO KENICHI
IPC: C04B35/66
Filed: 1990-09-27
Abstract: PURPOSE:To improve the service life of the trough material for the lining refractories of a blast furnace tapping through, etc., by compounding a specific ratio of zirconium boride with the raw materials for the refractory material. CONSTITUTION:This pouring trough material is formed by compounding at 0.5 to 5wt.% the zirconium boride (ZrB2) with the raw materials for the refractory material. The ZrB2 is compounded as the sintering assistant and the B therein has the effect of lowering the energy of the grain boundaries and to facilitate sintering. The ZrB2 has the high melting point, does not form liquid phase to hinder the compassion of the structure to be applied, and forms the protective layer consisting of the dense multi component oxide coating the surface of the body to be applied by reacting with hardly sinterable materials, such as, for example, silicon nitride, silicon carbide and carbon. The desired effect is not exhibited if the compounding ratio of the ZrB2 is below 0.5%. The B generated by the decomposition and the silica-content in the refractory raw materials generate the liquid phase of a low m.p. in the structure by the intervention of an alkaline, such as slag, and the corrosion resistance is degraded if the compounding ratio exceeds 5%.

Title: Developer for electrophotography
Inventor: TSUBUSHI KAZUO
IPC: G03G9/087
Filed: 1988-10-18
Abstract: PURPOSE:To improve fixability, offset resistance and blocking resistance by incorporating a specific fluorine-contained graft copolymer as a resin component into the developer. CONSTITUTION:The fluorine-contained graft copolymer formed by graft polymerizing a fluorine-contained monomer with a polymer or copolymer of olefin is incorporated as a resin component into the developer. This fluorine-contained graft copolymer exhibits water repellent and oil repellent properties as compared to commercially marketed alternately polymerized or random polymerized fluorine-contained polymers; in addition the copolymer has excellent solubility in solvents and is hardly stickable to a heat roller at the time of heat roller fixing in the case of using the developer for a toner for electrophotography. Generation of offsetting is, therefore, obviated and the resin having the low softening point is usable for the toner material. The blocking resistance, fixability and offset property are improved in this way.
