Title: Numerical controller
Inventor: IWAWAKI AKIRA
IPC: G05B19/4155
Filed: 1986-12-01
Abstract: PURPOSE:To improve the working factor of a numerical control NC device by dividing the data for control of NC machine tools into the integrated control data (automating function data) and individual working data (NC data) and therefore omitting the process of an abnormal working means to handle the subsequent normal working means with preference. CONSTITUTION:The NC control is carried out with transmission of an NC instruction and the working data are called out of a memory 20 in a prescribed sequence. Then a working instruction is given to an NC working machine 50 and the working processes are successively carried out. While the working process is coincident with 'drill lower hole processing', for example, and a drill is broken. In such a case, this abnormality is detected by an abnormality detecting means 60 and fetched by a control part 30 for reference to an integrated control data program 200. Here the program 200 omits the 'lower hole processing' and its inseparable 'tap processing' according to a conditional jump given at the time of abnormality. hereafter other processes are successively carried out. In such a way, the abnormal working processes are omitted to advance the normal processes. As a result, the working factor of an NC machine tool is improved.

Title: Line switching device
Inventor: UCHIKURA KAZUNORI
IPC: H04B1/74
Filed: 1988-11-11
Abstract: PURPOSE:To execute desired line switching by supervising whether or not desired line switching by a relay switch is executed at a supervisory section after a switch command is given from a control section and informing the monitor information to the control section. CONSTITUTION:Suppose that a switch is thrown to pass the data of a standby line 16B and a line switch control signal to pass a data of an active line 16A is given from a line switch control section 4, then a collation section 53A of a check circuit 5A supervises it that a desired line changeover by a relay switch 3A is executed after the switch command is given from a minicomputer 13A. If it is detected by the check circuit 5A that the switch 3A does not execute the desired line changeover, a bypass switch 7A closes a bypass 6A to execute the desired line changeover. Thus, the possibility of mis-discrimination that the line is switched is precluded.

Then the resist is developed so that the resist 2' except for the light-shielding layer pattern remains, and the substrate is etched so that the transparent conductive film 6' in the light- shielding layer pattern remains on the transparent substrate 1. Then the transparent substrate 1 is dipped, for example, in an electrodeposition soln. of a polymer resin containing a black pigment to perform electrodeposition by using a DC current and the transparent conductive film 6' as an electrode.  Thus, a light- shielding layer 4 having a polymer resin 7 containing a black pigment electrodeposited on the transparent conductive film 6' is obtd.

IPC: G11B7/24047
Filed: 1990-10-24
Abstract: PURPOSE:To eliminate burrs produced by the protrusion of ultraviolet curing resin by a method wherein trenches surrounding a recording region are provided. CONSTITUTION:Ultraviolet curing resin 2 is supplied onto a stamper 1 and an optical disk substrate 13 is placed. If a pressure is applied to the substrate 13 by a pressing flat glass 4 to make the resin 2 flow and spread, the resin 2 spreads in the part where the substrate 13 and the stamper 1 overlap each other and the excessive resin 2 flows into trenches 15 and 16. Therefore, the protrusion of the resin 2 from the part where the substrate 13 and the stamper 1 overlap each other can be avoided and a process for removing burrs which are produced when the protruding resin 2 is cured can be eliminated.

Title: Inspection device for lead bending in ic device
Inventor: HIROKAWA HIDEO
IPC: H01L21/66
Filed: 1990-10-26
Abstract: PURPOSE:To ensure inspection with a simplified construction irrespective of the types of devices by providing a cover member making contact for the upper portion thereof with a lead of an IC device installed in a base member and detector means for detecting the height of the cover member. CONSTITUTION:When a device D1 is placed on a base member 21, it is contained in a lead reception recessed part 21a if each lead part L1 is lowered to a position where it makes contact with the bottom surface of the lead reception recessed part 21a. It is assumed that one lead part L1' is bent left and right beyond an allowable limit. Thereupon, a cylinder 6 is actuated to lower an elevation block 2a. Hereby, a protrusion 22a provided on a cover member mounted on the elevation block 2a makes contact with the lead part L1. Although the cover member 22 is brought into close contact with the lead part L1, the lead part L1 is not deformed through pressurization. An air sensor 14 detects the height of the cover member 22 (or the height of the elevation block 2a). It is thus possible to detect whether or not the lead part L1 is bent beyond the allowable range.
