Title: Method of forming separate spacing
Inventor: RAIMUNTO BURIYUTSUKUNERU
IPC: F27D27/00
Filed: 1993-12-01
Abstract: PURPOSE: To prevent the interadhesion of materials, more particularly molten metal and a solid and to enable the relative movement of both materials by forming a separating space between the at least two materials which wet or deposit or adhere to each other when the materials are brought into contact with each other by exciting the at least one material on account of mechanical vibration. CONSTITUTION: An immersion pipe 1 consisting of refractory ceramic material is mounted at the bottom of a metallurgical container 2. The passage 3 of the immersion pipe 1 is helpful for passing molten steel. An ultrasonic generator 4 is mounted at the immersion pipe 1. This generator 4 applies the ultrasonic vibration of the frequency exceeding 20 kHz to the immersion pipe 1 as the solid. The vibration propagates the wall body 5 of the passage 3 within the immersion pipe 1. As a result, the sustained contact of the molten metal with the wall body 5 is prevented by the high-frequency vibration and, therefore, the separating space is generated between the molten metal flowing in the passage 3 and the wall body 5. The adhesion of the solid materials, more particularly Al2 O3 particles to the wall body 5 is prevented by this separating wall.

Title: Method of driving two-phase brushless motor
Inventor: NAITO HAYATO
IPC: H02P6/08
Filed: 1999-12-01
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption in a two-phase brushless motor with a simple structure without generating current ripple and electromagnetic noise. SOLUTION: The on/off operation of two-phase driving coils L1, L2 in the driving circuit 1 of the two-phase brushless motor is conducted alternately at the same cycle and in opposite phases by means of switching signals SW1, SW2. The counter-electromotive voltage developed by the driving coil L2 on the side turned off generates regenerative current IL2, which is fed as driving current to the drive coil L1 on the other side turned on. The two-phase driving coils L1, L2 feed the regenerative current to each other, thereby providing more saving of supplied current from the outside than in the conventional way and preventing the supplied current from changing suddenly into a rectangular wave shape. It is also possible to attain this driving method easily only by adding the switching signal.

Title: Transparent conductive film
Inventor: MARUYAMA HIRONORI
IPC: B32B9/00
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To make film thickness thin and an etching property improve without deteriorating transparency and durability by a method in which a film of specified thickness containing indium oxide as a main component is laminated on a polymer film, and on it is laminated a film containing indium oxide as a main component to make the total thickness a specified value. SOLUTION: In the preparation of a film (ITO film) containing indium oxide as a main component in vacuum, when the film is made once, the specific resistance is increased by gas generated from the polymer film. Therefore, an ITO film lower layer 2 of 50-100Å thickness is laminated on a polymer film substrate 3. Moreover, on it, an ITO film upper layer 1 of 250-1500Å thickness is laminated to make the total thickness 300-1600Å. In this way, gas generated from the substrate 3 in making the layer 1 is reduced by the layer 2, preventing the specific resistance from increasing. If the same sheet resistance is aimed, one having lower specific resistance can be made thinner.

Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To improve fuel consumption rate and to clean up exhaust gas due to complete combustion by changing the compression ratio of an internal combustion engine according to a driving situation in order to always keep mean effective pressure high from low load to high load and improve indicated thermal efficiency. SOLUTION: A compression ratio improving device 1 has a structure wherein a plunger 8 and a rack gear shaft 7 are driven according to a load by a hydraulic cylinder 9 to rotate a gear 6 meshing therewith, thereby rotating an upper middle back plate A and a lower middle back plate B which are integrally formed with the gear 6. The upper and lower middle bearing metals A, B move a shaft center position of main bearing metals 4, 5 and crank journal 10 at the time of rotating because of an eccentric structure thereof, thereby changing a top dead center position and a bottom dead center position of a piston. At the time of low load, a space capacity is made to be small by moving up the top dead center position of piston, which causes a high compression ratio state.  And at the time of rated road, the space capacity is made to be large by moving down the top dead center position, which decreases the compression ratio.
