Filed: 1994-05-26
Abstract: PURPOSE:To accurately grasp the attitude of a BGA package by detecting a solder ball as images of plural small grains having area larger than a specific minimum value and less than a specific maximum value, and finding the gradient of the package from the gradient of the straight line connecting those images. CONSTITUTION:When the package is gripped by the grip part of a surface mounting machine, the package is conveyed to in front of the photographic lens of a camera 1. The camera 1 picks up an image of solder balls arrayed on the bottom surface of the package and the image data are stored in an image memory 3. Then, a CPU 6 starts a specific program. Namely, a detecting means (CPU) 6 when supplied with image data on the bottom surface of a ball grid array(BGA) type package, detects images of plural small grains having area larger than the specific minimum value and less than the specific maximum value. Those images correspond to the solder balls of the BGA type package. Then, an arithmetic means (CPU) 6 finds the gradient of the package from the gradient of the straight line connecting those images.

Filed: 1977-11-14
Abstract: PURPOSE: To meet the requirements of a steam turbine system for quick response by constituting the load setting device therefor such that it allows quick change of a load setting signal thereto to a degree.  
     CONSTITUTION: When a first lower value selection circuit 43 provides an output which is equal in value to an output of an amplifier 42, a second lower value selction circuit 46 provides a load signal S which is thus equal to the output of the amplifier 42. If the load setting signal is quickly changed to be a value L 2 , the output of the second lower value selection circuit 46 at first follows the load setting signal until the load setting signal reaches a value L n  determined by a load change width limit setting signal, and it thereafter increases up to the value L 2  as the output of the first lower value selection circuit 43 increases up to the value L 2 at a  fisced ratio determined by a load increase ratio signal whereafter it is held at the  value L 2 . By such constitution, the requirements of the system for quick response  are met, and a load setting can be effected without having any ill effect on the  mechanical durability of the turbine and so on.

IPC: B41J2/045
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To freely change ink jet quantity by selecting the cycle of Helmholtz natural vibration as a unit pulse width and setting a specific value of the unit pulse width or a time equal to or less than the specific value to a quiescent time to alternately repeating a drive pulse and the quiescent time. SOLUTION: The cycle of Helmholtz natural vibration is selected as unit pulse width and used as the drive pulse of a piezoelectric element 4. A time equal to or less than 1/5-1/4 the pulse width is set to a quiescent time and a plurality of drive pulses and the quiescent time are combined. The piezoelectric element 4 is constituted so as to extend by the potential difference between signal input terminals 5a, 5b and, at the time of contraction, a vibration plate 3 is bent upwardly and a pressure chamber 2 is filled with ink. Subsequently, when potential difference is again generated, the piezoelectric element 4 is restored and the vibration plate 3 is also deformed to emit ink droplets from an orifice 1. By this constitution, by the repetition of a relatively simple pulse shape, ink jet quantity can be changed.

Title: Device for automatically detecting leak in hollow yarn ultrafiltration membrane module and giving alarm
Inventor: AZUMA TATSUO
IPC: B01D65/10
Filed: 1988-06-03
Abstract: PURPOSE:To automatically detect a leak in hollow yarn and to give an alarm by applying air pressure to the inside of the hollow yarn, automatically measuring the amt. of air appearing on the outside of the yarn and making an alarm work automatically when a prescribed amt. of more of air is measured. CONSTITUTION:A soln. is treated with a hollow yarn ultrafiltration membrane module incorporated into a soln. treating apparatus. At the end of the treatment, valves 1, 2 are closed, a valve 3 is opened and air is introduced into the inside 14 of the hollow yarn 13. The stock soln. remaining at the inside of the yarn is filtered by the air pressure and flows to the outside of the yarn, so the soln. on the inner surface of the yarn disappears and the air pressure becomes uniform. After the lapse of a certain time, the flow rate of air is measured with a flow rate sensor 5. When the measured flow rate is a prescribed value or above, a leak is judged to be present and an alarm is given.

Title: Walking beam controller
Inventor: MAEDA ICHIRO
IPC: B65G25/02
Filed: 1995-06-02
Abstract: PURPOSE: To increase initial position detecting accuracy so as to provide a proper switching timing by correcting the position of a first carried material from the flow rate of walking beams after stop control and the position of a sensor for detecting the carried material passing through an interfering part and allocating a position correction amount according to the distance of each carrier material. CONSTITUTION: A stop command is output when a middle sensor 16 detects a first steel piece 2 (2a), and the steel piece 2a slightly flows to an extraction side. Thus, by using a steel piece insertion positional signal 18 from a charger 3 as an initial value, the stroke signals of a front face walking beam 6 are received and positions are sequentially renewed. Then, when the middle sensor 16 detects the steel piece 2a, the flow rate 22 of each steel piece 2 thereafter is calculated, and by adding a correction amount ΔLs to the previously renewed steel piece position (dot line 2) the renewed position of each steel piece 2 (2a) this time is obtained. The positions of subsequent steel pieces 2 are corrected according to this correction amount. Thus, the steel piece positions at the initial time are coincided with real positions and a switching timing is surely understood.

Filed: 1983-07-27
Abstract: PURPOSE:To avoid un accessable state of a network only by the processing in terms of hardware by adding a pattern for initial setting of a packet reception circuit at least one of bits just before a head flag of a packet and just after a trailing flag. CONSTITUTION:It is supposed that a head flag FH102 is modified by a bit error on a ring form network. Since the head flag FH102 is not detected at first, a packet reception circuit 10 is brought into the packet arrival state when the trailing flag FT108 is inputted. Since an added pattern A109 is inputtednext on the other hand, the packet reception circuit 10 is applied with initial set. A packet transmission circuit 11 adds respectively added patterns A101 and A109 to the bit just before and just after the trailing flat FT108. Thus, the trailing flag FT108 is detected as an ineffective flag and circulated on the ring form network without giving any effect on the other packet.
