Title: Inspecting device for lead of semiconductor device
Inventor: KIMOTO NOBUYO
IPC: H01L21/66
Filed: 1989-09-19
Abstract: PURPOSE:To make it possible to recognize the boundary area between an inspection base and a lead with accuracy by allowing to comprise an image reflection base to which a semiconductor device is installed, an illumination system which illuminates the semiconductor device, and a camera device which pictures the reflection light. CONSTITUTION:A lead testing device comprises an image reflecting plate 11 made of a material which transmits light from one direction and reflects light from the opposite direction, a black-colored adjusting base 12 which adjusts a semiconductor device, a testing base 13 with an illumination device 7 which illuminates a lead section of a sample 2 from the sides and the lower side, and a CCD camera which is laid out at a slanting and upward position to the lead 10 of the sample 2. The sample 2 of the semiconductor device is placed on the adjusting base 12 and the lead 10 is illuminated by direct light from the illumination device 7 from above and below. Therefore, the lead 10 of the semiconductor device and the lead 10 of the semiconductor device reflected on the image reflecting plate 11 can be recognized as a uniform positive image all over the surface while the other adjusting base 12 and sample 2 can be recognized as a negative image. As a result, it is possible to recognize accurately the images around the boundary between the lead and the image reflecting plate, thereby preventing misunderstanding.

Title: Asynchronous signal selection circuit
Inventor: ODAWARA HIDEYUKI
IPC: H03K17/00
Filed: 1990-09-10
Abstract: PURPOSE:To prevent a pulse waveform with a narrower width than that of an asynchronous signal at signal switching by selecting the timing of an output selection signal fed to a multiplexer to be a timing when both asynchronous signals before/after switching are logically at a high level. CONSTITUTION:When asynchronous signals 1, 2 are inputted to the selective circuit and the level of a selective signal 3 is changed from a high level to a low level, a falling detection circuit 5 outputs a logic low level synchronously with the rise of the asynchronous signal 2. Since the asynchronous signal 1 is used as the enable signal E of a latch 7, the output signal of the latch 7 is inputted to an R-S latch 9 while the asynchronous signal 1 is at a high logic level, the output of the R-S latch 9 goes to a high logic level and the output of a multiplexer 8 is an input signal 2. When the selective signal 3 is changed from a low logic level to a high level, a rising detection circuit 4 outputs a low logic level synchronously with the rise of the asynchronous input signal and the output of the multiplexer 8 is an input signal 1.

Title: Output device for image sensor
Inventor: MURAMATSU SADAO
IPC: H04N5/372
Filed: 1987-09-28
Abstract: PURPOSE:To obtain a highly accurate amplified output regardless of the degree of the contrast ratio of incident light by detecting the brightness difference of the light incident on an image sensor, and setting the amplification degree small when the brightness difference is large, and large when the brightness degree is small. CONSTITUTION:The brightness difference in the light incoming to the image sensor is obtained by a monitor means, and the amplification degree of a differential amplifying circuit 33 is set in accordance with the brightness difference beforehand. Thereafter, the video signal of the image sensor and the detecting signal of a minimum light detecting circuit 27 are inputted to the differential amplifying circuit 33. Then, the differential amplifying circuit 33 is constituted so that only the changed element of the video signal may be amplified, the signal may be outputted at the small amplification degree when the brightness difference in the light is large, and the signal may be outputted at the large amplification degree when the brightness difference in the light is small. Consequently, a digital conversion by an A/D converter is made easier, and the highly accurate converter output is obtained.

Filed: 1991-09-20
Abstract: PURPOSE:To prevent defects of a woven fabric from extending by automatically and rapidly finding out miss-feeding of a feeder or a faulty feeder. CONSTITUTION:When a feeder 1 is exchanged, a detector 310 detects wefting conditions, e.g. weft yarn-unwinding timing at a prescribed lag time after exchange of the feeder, travel time, short pitch frequency and injection break frequency. A judging unit 311 compares the detected wefting conditions with the preset wefting conditions and, if the detected wefting conditions are beyond the range of the preset wefting conditions, gives a judgment of abnormal feeder supply. A prohibiting device 313 receives the judgment of abnormal feeder supply and subsequently prohibits redriving of the loom till receiving a signal of repairing-completion of abnormal feeder supply from a manually operated direction unit 312. When the prohibiting device 313 receives from the direction unit 312, redriving of the loom is started.

Abstract: PURPOSE:To improve the use efficiency of a recording liquid to accomplish a small-sized container by a method wherein an ink is suctionally removed so that an amount of ink held in an area of a porous body only on the side of an air communicating port is smaller than that held in an area of an ink discharge part. CONSTITUTION:The pressure in an ink tank is reduced, and an ink is injected from a supply port 1200 so as to fill all through the ink tank. In this manner, a porous member 902 can be fully charged with the ink. A suck-out port 1401 is opened with the supply port closed, and the excess of the ink over a predetermined recording liquid injection amount is sucked out from the suck-out port. A gap between the supply port 1200 and the suck-out port 1401 is determined to be as proximate to a maximum dimension in a liquid jet recording head as possible and desirably meets a relation of (l1/l2)>=0.7. In this manner, the recording liquid is distributed to be concentrated on the side of the supply port, whereby the ratio of a suppliable ink amount to an injected ink amount is raised to approximately 80% or more.

Abstract: PURPOSE:To run a running body precisely so as to follow an inherent running line by installing a running line detecting sensor, a liquid level detecting sensor, and a laser beam detecting sensor, an inclined angle detecting sensor and a position detecting sensor on the running body. CONSTITUTION:A welded part detecting sensor 25 mounted on a running body running on a container, detects a welded part 6 so as to run a running body the use of the detected welded part 6 for navigation. However, since there is presented a position where no detection signal can be obtained due to a small difference in metal grain boundary, another signal is used for navigation at this position, instead of the above-mentioned detection signal. That is, in the case of a circumferential direction of the container, a pressure sensor mounted on the running body detects a level of liquid so as to know the height of a welded part, and the running is controlled in accordance with the signal. Further, in the case of the vertical direction of the container, a laser beam is set on the welded seam, and is detected by a light receiving line sensor 26 mounted on the running body while the posture of the running body is detected by inclined angle sensors 30, 33 so as to control the posture of the running body.
