Filed: 1989-10-30
Abstract: PURPOSE:To draw a graphic on a screen with the sense of handling the head of a free parallel rule device and writing tools by allowing one cursor device to move and rotate a right-angled scale line and allowing the other cursor device to designate a coordinate position. CONSTITUTION:When an operator draws the graphic on a digitizer 4, the right- angled scale line on the digitizer 4 is moved to a target position, rotated by a deseired angle to draw the graphic on the digitizer with the right-angled scale line as a reference by operating a second control cursor device 54. Even if the designated position of the cursor device 6 does not coincide with the scale of the right-angled scale line when the first cursor device designates the one scale of the right-angled scale line 64, the designated position is rounded by the scale in the shortest distance from the designated position, and the coordinate of the scale is inputted to a controller as the coordinate of the designated position. Thus, an operation can be executed with the sense of handling the free parallel rule.

Title: Laser beam machining method
Inventor: NAKADA YOSHINORI
IPC: B23K26/38
Filed: 1990-10-18
Abstract: PURPOSE:To sharply machine an acute angled shape part without using a conventional loop machining by changing a laser output in accordance with a feed rate front and behind the acute angled shape part. CONSTITUTION:When machining approaches to the acute angled part, machining movement is decelerated and stopped and in accordance with it, an output command of laser beam is changed from a cutting condition to a piercing condition. In other words, when heat gain in a corner part is reduced, the corner part is turned and machining movement is reopened, the output command of laser beam is changed from the piercing condition in sequence to the cutting condition. In this way, when the feed rate decelerates or accelerates front or behind the corner part, the output command A of laser beam is changed corresponding to the change of the feed rate in this plan. Consequently, though movement is stopped at the corner part and piercing is performed. the roughness of the machined surface is not deteriorated and the corner part can be machined sharply without applying the loop machining.

Title: Level converter from ecl logic level to ttl logic level
Inventor: KEBIN EMU OBUNSU
IPC: H03K19/018
Filed: 1990-10-18
Abstract: PURPOSE: To gradually reduce a delay time at the time of conversion by connecting an ECL gate to a voltage regulator, inserting the threshold voltage of non-ECL gate in the deflection width of voltage in an output by this and directly driving non-ECL gate with the output of the ECL gate. CONSTITUTION: An output terminal of an ECL gate 42 is directly connected to a TTL gate 44, and a regulator 46 is connected to the gate 42. At the time of operation, because the gate 42 directly drives the gate 44, a delay time does not occur to make level shift of an output of the ECL gate. Secondarily, because an output terminal of the regulator 46 is serial to the gate 42, there is hardly increase of power consumption. Furthermore, because the conversion of logical level of a signal from the ECL gate is carried out by using only either a positive phase or a compensatory phase of the ECL gate, the other phase is allotted to execution of an logic operation in a feedback or other circuits.

Abstract: PURPOSE:To obtain the high responsibility and stability of torque by calculating the current phase from the detected value when the difference between the primary current command and the detected value and by adjusting the current phase to the change in size of the actual current. CONSTITUTION:Usually a phase angle switching selector 21 selects the output thetaof an inverse tangent function machine 13, but when the deviation DELTAI of the primary current detected value I1 from the primary current command value I1* is more than the comparison level, the current phase angle theta is selected by conversion with an inverse cosine function machine 19 from the primary current detected value I1 and exciting command value I m*. In the inverse cosine function machine 19 the current phase is smoothly changed, adjusting to the actual current size. On this account, the exciting current I m is almost constant and the flux phi of a motor 5 is also almost constant, so that the torque changes smoothly.
