Title: Iron core of electric rotating machine
Inventor: KANEDA TAKASUKE
IPC: H02K1/18
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To attain relatively high efficiency both in high-rpm drive range and in high-torque drive range, by laminating steel plates of high permeability and low magnetic flux density and steel plates of low permeability and high magnetic flux density in specified proportions to form the iron core of an electric rotating machine. SOLUTION: An outer core 10 is formed by laminating two types of steel plates: first steel plates 12 and second steel plates 14. The first steel plates 12 are formed of a material high in permeability and low in saturation magnetic flux density (high- permeability, low-magnetic flux density material), and the second steel plates 14 are formed of a material which is low in permeability and high in saturation magnetic flux density (low-permeability, high-magnetic flux density material). Examples of the high-permeability, low-magnetic flux density material include sendust and electromagnetic steel plates obtained by adding silicon or aluminum to iron, and 80% Ni-Fe (Permalloy (R)). Examples of low-permeability, high-magnetic flux density material include Fe- 50%Co (Permendur (R)) and pure iron. The properties of the material can be brought only when it is close to those of the first steel plates 12 or second steel plates 14, only when appropriately selecting the volumetric ratio of the first and second steel plates 12 and 14.

Title: Preparation of formed coal
Inventor: SATO SHINKICHI
IPC: C10B57/04
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To raise the compounding ratio of bony coal without lowering the strength of coke by preparing formed coal using bony coal as a part of raw materials with incorporation of coke breeze of a specific particle size in a specific ratio. SOLUTION: In preparing formed coal using bony coal as a part of raw materials, coke breeze having a particle size of 1 mm or less is compounded in a compounding ratio of at most 20 wt.%. In a process for forming coal wherein bony coal is collectively compounded, there can be exemplified, as one method to effect improvement of strength of coke, incorporation of strongly caking coal with a low volatile matter content. However, the compounding ratio of bony coal is 60-70 wt.% at most, because strongly caking coal also has a volatile matter content of 15-20%. Thus, it has been expected to provide a method to increase the compounding ratio of bony coal without lowering strength of coke. According to the present invention, it is possible to increase the compounding ratio of bony coal as much as 85 wt.% while using, for example, 15 wt.% of coke breeze.

Where the composition ratio of nitrogen is below 60%, it is of the composition that the silicon is excessive, in which N/Si is becomes smaller than 1.33. when the silicon becomes excessive, conductivity occurs.

Filed: 1989-09-27
Abstract: PURPOSE:To stabilize a fixing temperature in a short time and to enhance power utilization efficiency by phase-controlling power supplied to a heater so that it may be equal to or below a set value only while working voltage exceeds the set value. CONSTITUTION:When a power source is turned on, a temperature sensor 4 detects the temperature of the heater 483 and transmits 'H' to an output circuit 2 from a control circuit 3. The circuit 2 transmits the 'H' signal D1 to the gate of a TRIAC 1 to turn the gate on. During on-peirod, the power i supplied to the heater 483 and the fixing temperature is attained in a short time. After detecting the temperature bythe sensor 4, 'L' is transmitted to the gate of the TRIAC 1 from the control circuit 3 through the output circuit 2 to turn the gate off, and the power supply is stopped. When the heater attains a lower limited temperature for fixing, the control circuit 3 transmits the 'H' signal to the output circuit 2 again. With such constitution, the set power is efficiently used and the time that a fixing roller attains the fixing temperature is shortened.
