A blank profile specifying method in automatic programming for lathes has a step of specifying a finished profile (1), a step of entering a maximum length (L.sub.m) and a maximum diameter (F.sub.m) of a blank profile (2), a step of obtaining the maximum length (L.sub.t) and the maximum diameter (F.sub.t) of the finished profile from entered finished profile data, a step of calculating an uncut thickness (t.sub.z) longitudinally of the blank and an uncut thickness (t.sub.x) diametrically of the blank by using L.sub.m, L.sub.t, F.sub.m, F.sub.t, a step of obtaining the blank profile (2) by enlarging the finished profile by the uncut thicknesses in the respective directions, and displaying the blank profile and the finished profile, a step of entering position data indicative of inflection points (P.sub.1, P.sub.2 . . . P.sub.5) of an actual blank profile, and a step of storing the entered position data indicative of the inflection points and modifying the display of the blank profile by using the position data.

A method and apparatus for creating numerical control data by entering coordinates which specify points on a drawing placed on a tablet. A minimum reading distance is preset at the time that coordinate values of points are to be entered from the tablet. This is followed by entering the coordinate values of prescribed points on the drawing by designating the points at random using a coordinate designating device. The coordinate values of the designated point are generated each time the coordinate designating device travels a distance equivalent to the minimum reading distance, or sampling pitch, as the device is moved continuously along a graphic appearing on the drawing. Then, numerical control data is created by using the generated coordinate values. Numerical control data approximating straight line segments can be readily created, even for curves other than straight lines and circular arcs, by setting the sampling pitch interval to a suitable value.

A numerical control device 102, in which a processor 102a numerically controls a machine tool 103, is provided with an external storage unit 201 for storing machining data conforming to various shape patterns, input means 202, an editing processor 102c and an internal memory 102d, in order to implement a function for the creation of numerical control information. Machining data, corresponding to a part code entered from the input means 202, is read out of the external storage unit 201c. The editing processor 102c creates numerical control information, which is stored in the internal memory, from the machining data and, e.g., numerical values input from the input means 202.

A graphic form or figure drawn on a drawing and larger than the read-out area of a tablet is divided into graphic patterns which are successively read by displacing the drawing. The extent to which the drawing is displaced is recognized, and graphic data read before and after the drawing is displaced is converted into data on one coordinate system and entered as inputs. For entering the graphic data, two points are specified on the drawing, and the coordinates of the specified points prior and subsequent to displacement of the drawing are read and stored in first through fourth registers. The stored coordinates and the coordinates of points on the figure are entered into a coordinate transformation unit which effects arithmetic operations of coordinate transformation.

This invention relates to a method of obtaining information of a specified or target area of a living body near its skin surface by the application of a nuclear magnetic resonance phenomenon (NMR). This invention comprises a static magnetic field generator for generating a static magnetic field H.sub.0, a radio-frequency magnetic field generator for generating a radio-frequency magnetic field H.sub.1 perpendicular to said static magnetic field H.sub.0 and having a nuclear magnetic resonance frequency f.sub.0, and means disposed in close proximity to said target area for focusing one or both of said magnetic fields thereon, and relates to a method of obtaining, with a high signal to noise (SN) ratio and with ease, information of a specified area of a living body from the outside or inside of the body.

A controller and a display device are connected to each other by a network. The controller comprises a network control program which controls a network control section to communicate with the display device for each of a plurality of operation modes, including an initialization mode, a normal action mode, and an alarm mode. Various data, such as operation mode information for the controller, are transmitted to the display device connected by the network through the network control section and display data is displayed on the display device.

A parts feeder is provided which is designed to pick up parts carried by a strip carrier. The strip carrier is moved intermittently to a pickup station and has storage chambers arrayed in a lengthwise direction thereof. The storage chambers has openings and stores therein the parts each of which has formed on ends thereof electrodes having at least a magnetic portion. A magnet which has a non-pole face oriented to the strip carrier is disposed at the pickup station for magnetically keeping each of the parts in a desired orientation within one of the storage chambers.

A joint structure connected to an air intake passage is composed of a throttle body having a set of a groove and a chamfered surface formed on an outer surface thereof diagonally opposite to each other and a joint member having a flexible arm and a rigid arm. The flexible arm has a ridge in engagement with the groove of the throttle body, and the rigid arm has a sloped surface in engagement with the chamfered surface of the throttle body.

A system for debugging a sequence program generated by flowcharting to allow a chronological flow of steps to be easily confirmed. A data display screen has a time display area which displays a succession of sampling times at predetermined time intervals, and a step number display area which displays the numbers of steps which are executed at the sampling times. The data displayed on the data display screen indicates that the steps of a parallel branch section require respective execution times corresponding to different sampling periods, respectively. As a result, it can be seen at a glance which steps determine the execution speed of the entire parallel branch section.

A road heater comprising (1) a linear heater which is comprised of a linear heating element and a flexible electrically insulating layer formed on the entire periphery of the linear heating element, and (2) an outer textile structure such as a braid which covers the entire periphery of the linear heater. The road heater has a compressive yield load (Lc) of at least 1,000 kg. The outer textile structure is made of a thermoplastic synthetic fiber, preferably, a polyester monofilament, having a melting point of at least 200.degree. C. and a single fiber fineness of at least 1,000 deniers. The linear heating element preferably comprises a flexible heat-generating mixed spun yarn composed of stainless steel fibers and heat-resistant electrically non-conductive fibers.
