Title: Method and device for inspecting lead bend of semiconductor device
Inventor: IMADA TAKASHI
IPC: H01L23/50
Filed: 1994-05-10
Abstract: PURPOSE:To reduce the scale of an inspection device and to reduce device cost by comparing the lead in one side surface direction of a semiconductor device with that in the other side surface direction of a semiconductor device for detecting deformation. CONSTITUTION:Reflection type displacement sensors 3 and 8 receive reflection light 3'' and 8'' after infrared rays or laser beams 3' and 8' are projected and output voltages proportional to the displacement of a lead 10 of a semiconductor device 1. When the semiconductor device 1 glides on a guide rail 2, the sensors 3 and 8 are set to low and high levels when there is sufficient reflection light 3'' and 8'' from the lead 10 and less reflection light 3'' and 8'', respectively, thus appearing as dots (a) and (b) at the output part of amplifiers 4 and 9. These two waveforms are compared by a signal comparison circuit 5 and the difference between two waveforms is outputted. At this time, when the two leads 10 are not bent, the waveform at a point (c) is at a lower level than the voltage at a point (d) of a threshold voltage, thus preventing a quality judging circuit 7 from outputting data. On the other hand, when one of two leads is bent, the difference in waveform exceeding the level of the point (d) appears.

Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To improve heat exchange efficiency so as to secure a sufficient amount of vaporized gas based on natural vaporization by introducing heat from the periphery of a shell plate according to an outside temperature for generating forced convection. SOLUTION: A partition wall 7 having a semicircular cross section concentric with a shell plate 2 is constructed of a gutter type steel plate with a substantially equal length to the shell plate 2 and arranged in the lower part inside the shell plate 2 at an interval 6, and both end edges 8, 8 of the partition wall 7 are positioned in the vicinity of the line crossing the center line 9 of the shell plate 2. In the lowermost end of the partition wall 7, a hole 11 is formed along the longitudinal direction. In this constitution, when heat is taken inside from the periphery of the shell plate 2, a liquid temperature on the inside face starts to increase, and accordingly, liquid in the circumference rises as shown by an arrow 13.  In this process, because a temperature in the center of the liquid is not increased and still kept low, the liquid is lowered to the bottom face (as shown by an arrow 14) and flows to the interval 6 from the hole 11, so that forced convection in the arrow 13, 14 directions is generated and heat efficiency is increased, and consequently, latent heat required for gasification is provided and a natural vaporization quantity is increased.

Abstract: PURPOSE:To improve the operability and to prevent the occurrence of an error based on the marking error of the operator by using a mark sheet so as to recognize a number of a transmission destination or a sender and so to eliminate key input in the transmission/reception state. CONSTITUTION:In the case of transmission, a mark sheet generating section 5 generates a sheet on which a concerned station number is marked based on a prescribed form, a read section 3 reads a transmission original and a destination is called to connect the line then the mark sheet is sent and an original is sent. Furthermore, in the case of reception, a sheet on which a sender number is marked is read by the read section 3, a mark sheet recognition section 6 recognizes the sender number and uses the number for the transmission of a reply text or the like to the destination. The operation required for informing the concerned station number is not needed by using the mark sheet so as to allow the opposite party to recognize the concerned station number thereby simplifying the transmission reception procedure.

Abstract: PURPOSE:To prevent a molten material from penetrating into a valve body while achieving a favorable degassing, by a method wherein a degassing valve in an opened condition is so engaged to be energized in the direction of a closed condition, and the engagement is released simultaneously with a closing action to close the valve completely. CONSTITUTION:A fixed mold 1 and a movable mold 2 are clamped, the valve 6 is lowered against a tension spring 13, and it is held in the opened condition by engaging it with an engaging mechanism 14 which consists of a recessed part 16 of a valve rod 6d and a ball 19 energized by a compression spring 18 provided at a valve rod guide part 12.

IPC: E02D5/20
Filed: 1994-05-11
Abstract: PURPOSE:To keep the quality of concrete good by preventing moisture in either part of the concrete poured into a shell from freezing prior to solidification. CONSTITUTION:A channel 4 is excavated in such a way that at least the portion of the channel from the surface of the ground to the underground side of a frozen soil portion 1 is broader than a shell 18, and a box-shaped steel sheet pile 10A is erected in the excavated channel 4 to form a shell 18, and the space between the portion of the channel 4 broader than the shell 18 and the shell 18 is backfilled with a heat insulating backfill 20 and concrete 21 is poured into the shell 18. Even if employed in the ground 3 having the frozen soil portion 1, the concrete 21 poured into the shell 18 does not transfer heat to the frozen soil portion 1 because of the heat insulating backfill 20, and so heat generated during the hardening of the concrete itself is not taken away by the frozen soil portion 1.
