Title: Ultrasonic machine with machining spindle of vertical and horizontal vibration
Inventor: KAYABA NOBUO
IPC: B06B1/04
Filed: 1986-10-31
Abstract: PURPOSE:To enable highly efficient processing in a horizontal direction as well by repeating the attraction and the repulsion of a horn through the change of the intensity of a magnetic field formed at the tip of the born in a ultrasonic machine. CONSTITUTION:An oscillator 3, a born 4 and a tool 5 are rotated at a high speed with a motor 6 and concurrently therewith, the oscillator 3 gives a vibration with an amplitude in a Z-axis direction due to the operation of an ultrasonic transmitter 1. The amplitude is expanded with the horn 4 and the vibration is transmitted to the tool 5. Therefore, the tool 5 gives a high-speed rotation and a high-speed vibration in a Z-axis direction. Also, a pulse current runs from a power supply part 20 to coils 11 via a control box 19 and generates a magnetic field around the four coils 11, thereby causing the high-speed rotation of the horn 4. Consequently, the intensity of the magnetic field working on the horn 4 changes momentarily and an electric current runs on the winding surface of an aluminium foil 16 opposite to the coils 11 due to the effect of electromagnetic induction, thereby causing the coils 11 (11-1 and 11-2) to repulse the horn 4 and supporting the horn 4 on the inclusion surface of a case 7 in a non-contact condition. And the horn 4 and the tool 5 repulse each other in X-and Y-axis directions and vibrate within an allowable limit in a space 13 in an overall horizontal direction.

IPC: H01M10/48
Filed: 1990-09-27
Abstract: PURPOSE:To presume the open circuit voltage during charging/discharging or immediately after it in a short time by generating a pause after discharge of a certain electric amount, measuring at several points the open circuit voltages immediately after the pause and after elapse of a certain period of time, and determining recursion equations of the open circuit voltages with the logarithmic values of different elapsed times from start of the pause to measurement. CONSTITUTION:Six storage batteries of rated capacity of 35 AH are discharged in advance and put in the condition with discharge depth 50%. followed by a pause after 5 min discharg ing with 10.8 A. The open circuit voltages 1, 3, 15, and 60 sec after start of the pause Y are plotted relative to the logarithmic values X of the pause periods in seconds, and their correlation is determined. The recursion equation at this time can be expressed as Y=2.030+0.013X(correlation factor +0.948) as shown by (A). Another pause is given after 5-min discharging with 10.8A, and the open circuit voltages 1, 3, 15, 60 sec after start of the pause Y are plotted relative to the logarithmic values X of the charging times in seconds, and their correlation is determined. The recursion equation at this time can be expressed as Y=2,158-0.028X(correlation factor-0.974) as shown by (B). If these two recursion equations are solved as simultaneous equation and Y is determined, it is given as Y=2.071(V), which can be used as an approximated value of the open voltage at this discharge depth.

Title: Continuous leaf sheet cutting device
Inventor: HIRANO MASAMI
IPC: B26D1/09
Filed: 1991-09-11
Abstract: PURPOSE:To cut a continuous leaf sheet even with a small down stroke of a cutter, which cuts the sheet at its perforation, by equipping the cutter with a sawteeth form cutting edge. CONSTITUTION:When a sensor senses that the perforation 7 of a continuous leaf sheet has come to the foremost of a receptacle table 6, rotation of rollers R, R' is once stopped. The rollers R, R' rotate so that a tension is applied in the direction perpendicular to the perforation 7 with the perforation 7 positioned in the center, and are stopped. Then a solenoid 4 is energized to sink a cutter 1, which cuts the sheet 5 at the perforation 7. Because the cutter 1 cuts the sheet with three saw-teeth cutting edges 1a arranged across the width, so that the cutting length shared by one cutting edge 1a is one third of the sheet S width, which reduced the burden on one cutting edge compared with a conventional arrangement using only one cutting edge. Further, the cutting can be done effectively because the sheet is pulled to the left and right centering the perforation 7.

Abstract: PURPOSE:To correct rotative speed for a prime mover in accordance with the state of work by a method wherein rotative speed correction characteristic is adjusted with a rotative speed correction value calculating part, and the rotative speed is adjusted in accordance with the adjusted correction characteristic. CONSTITUTION:A rotative speed correction value DELTAN is obtained from correction characteristic adjusted with signals X1-X4, in proportion to the manipulated variable of rotative speed correction characteristic adjusting dials 58a-58d in accordance with discharge pressure Pp of an oil-hydraulic pump. As the pump discharge pressure Pp exceeds a specified value Pu, arbitrarily adjustable with a speed increasing pressure setting dial 58b, a function generator 820 starts outputting rotative speed correction value DELTAN1 in accordance with increase characteristic NCup. However, the outputted correction value DELTAN1 does not vary until the pump pressure decreases from the present value by (Pu-Pd), and when the pump pressure decreases by more than (Pu-Pd), the generator starts outputting the rotative speed correction value DELTAN1 in accordance with decrease characteristic NCdw. At this time, the specified value Pd is adjusted by operating a speed decreasing pressure setting dial 58a, the rotative speed correction value DELTAN1 is adjusted by a speed increasing amount setting dial 58c, and the length of delay for returning the rotative speed correction value DELTAN after the increase to zero is adjusted by a delay setting dial 58d.

Abstract: PURPOSE: To make it possible to form a diamond film having high adhesive power to a substrate consisting of an arbitrary material by subjecting the substrate surface to chemical modification of adamantane or its deriv. at the time of depositing the diamond film on the substrate surface by forming active carbon species.  
     CONSTITUTION: Various methods of vapor growth methods are adoptable for depositing the diamond film on the substrate surface by forming the active carbon species.
