Patent EP-0542729-A2 (EP)
Inventor: DECKARD CARL E
IPC: B23K26/08
Filed: 1987-10-14
Abstract: A method and apparatus (10) for selectively sintering a layer of powder to produce a part comprising a plurality of sintered layers. The apparatus includes a computer (40) controlling a laser (12) to direct the laser energy onto the powder to produce a sintered mass. The computer either determines or is programmed with the boundaries of the desired cross-sectional regions of the part. For each cross-section, the aim of the laser beam is scanned over a layer of powder and the beam is switched on to sinter only the powder within the boundaries of the cross-section. Powder is applied and successive layers sintered until a completed part is formed. The powder may consist of a plastic, metal, ceramic, or polymer substance. In the preferred embodiment, the aim of the laser is directed in a continuous raster scan and the laser turned on when the beam is aimed within the boundaries of the particular cross-section being formed. Preferably, the powder dispensing mechanism includes a drum which is moved horizontally across the target area and counter-rotated to smooth and distribute the powder in an even layer across the target area. A downdraft system provides controlled temperature air flow through the target area to moderate powder temperature during sintering.

Abstract: According to this invention, word line drive circuits (14a - 14c) are respectively connected to memory cell arrays (11 - 13). These memory cell arrays (11 - 13) are respectively driven by the word line drive circuits (14a - 14c). Therefore, the potential of a normal word line selected simultaneously with a word line in which a failure has occurred and which is included in a memory cell array can be prevented from being decreased so as to prevent the normal word line from the failure. For this reason, the yield can be increased without unnecessarily using a redundancy circuit.

Abstract: A velocity estimation technique is provided for a pulse-echo ultrasonic diagnostic system in which a two dimensional array of samples is acquired from a sample volume. The two dimensions of the array are depth, in which echo signal samples are acquired in response to transmission of a pulse to the sample volume, and pulse time, in which samples are acquired in response to transmission of the pulses in the pulse ensemble to the sample volume. Two autocorrelation calculations are performed on the array, one in the depth dimension and another in the pulse time dimension to yield two correlation functions, the first related to echo frequency and the second related to the Doppler frequency. The two correlation functions are then employed in a Doppler velocity estimation to determine the velocity of motion at the sample volume. The technique utilizes the full information content present in the bandwidth of the received echo signals, thereby overcoming inaccuracies due to depth dependent frequency decline or coherent signal cancellation. Since accuracy is premised upon the number of samples in the array and not its size in a particular dimension, performance can be tailored to favor frame rate or axial resolution while maintaining the accuracy of velocity estimation.

Abstract: This invention aims to prevent terminal metal fixtures in an L-shaped bulb socket from being exposed and to positively hold the fixtures. Each terminal metal fixture 1 is inserted into a fixture accommodating chamber 15 in an axial direction of a connector inlet port 9 through a fixture insertion opening 17 formed in a rear wall of a housing 7 while a male terminal 5 of the fixture 1 is being fitted to a through-hole 14 formed in a fixture holding wall 13. Then, a lid member 19 is thrusted in the opening 17 in an axial direction of a bulb inlet port 8 on a thrust groove 21 formed in an end face of the bulb inlet port 8. Thus, the opening 17 is covered by the lid member 19. A side plate 4 of clamp portions 2 of each terminal metal fixture 1 is clamped in a space between a stepped face 24 on the housing 7 and the lid member 19, thereby preventing the fixture 1 from moving vertically or horizontally. Also, the male terminal 5 is closely fitted in the through-hole 14, thereby preventing the fixture 1 from moving.

Abstract: A container has a drop gate and lids that open along hinge joints formed at the upper end of the side walls. The drop gate is formed in one end wall and the lids can also be opened half way from the end wall in which the drop gate is formed. In this way, access to the interior of the container can be gained through the open drop gate and the open half of the lids so that the container can be used as a shelf box or hopper in a flow racking system. Further, when the lids are opened along their respective side wall hinge joints, the container can be used as a distribution tote. When the container is also used as a bulk shipper by vendors or suppliers, the container can perform three functions in a distribution system. Specifically, the container can be first used as a bulk shipper, then, without unpacking the goods, the container can be shelved on a flow racking system from which orders can be selected at a distribution center. Finally, the container can be used again for shipping the goods from the distribution center to retail outlets and returned to either the distribution center or suppliers in a nested stack.
