Title: Programmable controller
Inventor: MITSUDA HAYAO
IPC: G05B19/05
Filed: 1985-12-26
Abstract: PURPOSE:To automatically inform a proper time point of conversion based on the actual working frequency of a designated relay or device, by using an informing means to inform that the integrated value reaches a reference level. CONSTITUTION:The control output signal is designated by a number and the reference value can be set for the ON time or the ON/OFF frequency in the form of the lifetime information. Here a programming console 8 is used to set the above-mentioned reference value and the set output number is stored in a register N of a data memory 4 with the reference value stored in a register C respectively. In an integration mode of ON time, the scan time component is subtracted from the time data of the register C as long as a specific number is kept ON. While in an integration mode of ON/OFF frequency, the change of the specific signal to ON from OFF is detected and decided and the frequency data on the register C is subtracted by 1 for each detection of said change. Then an alarm 9 is started when the contents of the register C are equal to zero to inform that the integrated value reaches its reference level.

Title: Time axis correcting device
Inventor: MURAKAMI HIROIKU
IPC: H04N5/956
Filed: 1990-10-29
Abstract: PURPOSE:To output a video without dancing in the vertical direction by delaying a write starting line from a read starting line by one line at the time of a first field of an input video signal when the field attribute of the input video signal and the field attribute of the reference synchronization signal is inconsistent. CONSTITUTION:The coincidence and incoincidence of the field attribute of the input video signal and the field attribute of the reference synchronization signal is detected by a comparator 10, and at the time of incoincidence, that is, when an advance synchronization 19 and an input video signal by 1 field are in reverse phase, the only 1st field is delayed by a write starting address latch circuit 12, and the readout is performed by the fixing of ten lines. Therefore, an output video signal 17 can be made keeping the interlace at the time of input even when mixed with a reference synchronization signal 37 of the reverse field attribute. Thus, the satisfactory video without dancing in the vertical direction can be outputted even to the input video signal where the framing is not taken against advancing.

Title: Device for polishing surface of cathode-ray tube
Inventor: ISHIKAWA TAKAAKI
IPC: H01J9/38
Filed: 1991-11-08
Abstract: PURPOSE:To simplify a surface polishing device by driving and rotating an elastic polishing stone using a motor, and providing an articulated robot for driving the stone three-dimensionally. CONSTITUTION:A motor 18 rotates a polishing stone 18 and an articulated robot 19 presses the stone 18 against a panel surface 10a. The stone 18 is deformed by an amount T because of its elasticity. The stone 18 is moved by the robot 19 to polish the whole panel surface 10a. The teaching point of the robot is such that if the amount T of deformation is subjected to linear interpolation in the direction of height within an absorbable range, the whole surface of the stone 18 copies the shape of the panel surface 10a. Filthy water generated by polishing is splashed by rotation of the stone 18 and does not enter the reinforcing metal fittings 10b of a cathode-ray tube 10. After the polishing is completed, the stone 18 returns to its original point and water from a nozzle 21 is splashed on the panel surface 10a to remove dirt and then water in the reinforcing metal fittings 10b is dropped by gravity. Then the cathode-ray tube is fed to a draining process with its panel surface 10a facing sideward and water is poured and air is injected so as to drain water off the panel surface 10a and then the panel surface is dried. Since the stone is an elastic body, a fine follow-up mechanism for the robot is unnecessary, and a cathode-ray tube holder and a positioning mechanism are unnecessary.

Abstract: PURPOSE: To reduce the consumption of high pressure blowing air in reduced apparatus cost by supplying high pressure blowing air flowing out of the molded container in a blow mold after the expansion of a parison to a low pressure air source during transfer and detecting pressure in a region where low air pressure does not exceed a predetermined value and discharging air so as to bring the container held in the blow mold to circumferential pressure after transfer. CONSTITUTION: Blowing pressure is supplied from a low pressure air supply source 15 up to a point of time of about 1.25 sec and the pressure level of the supply source 15 is about 10-25 bar. However, within this time, the expansion of a parison 3 and the volumetric increase caused thereby generate the wake of compressed air and the pressure drop caused by originally present flow resistance also occurs and, therefor, supply pressure does not change in the region of a container to be molded. On and after the point of time of about 1.25 sec, compressed air is supplied from a high pressure blowing air supply source 16. After about 1.7 sec, the pressure in the container reaches an almost final value of about 36 bar during molding. The typical pressure range in the supply source 16 is 25-40 bar.  After about 2.2 sec, the supply from the supply source 16 is completed and exhaustion is executed until circumferential pressure is obtained and completed after about 2.7 sec.
