Title: Spatial filter of foreign matter-inspecting apparatus
Inventor: YANAI TOSHIAKI
IPC: G06T7/00
Filed: 1994-07-08
Abstract: PURPOSE:To obtain a spatial filter having a good transmittance to a scattering light of a foreign matter, by forming a light transmitting part in a light-shielding plate by cutting parts other than a Fourier transformation pattern. CONSTITUTION:A light-shielding plate 81 of a suitable material is prepared. The part other than an image PTM' is cut from the light-shielding plate 81 with reference to the image PTM' of a Fourier transformation pattern, and the cut-out part is used as the transmitting part for scattering light from a foreign matter. The part is cut with a cutter, a hole puncher, etc. If a separated part is present in the image PTM', the part is connected to the periphery or the like of the light-shielding plate 81 to prevent the part from moving. However, the connected part should be punched or the like so as not to shut light as much as possible. A patterned light-shielding filter formed in this manner is fixed to a suitable frame 82 and mounted to a Fourier transformation face to be used as the spatial filter. At the inspecting time, a laser beam is sequentially cast on each memory chip of a wafer to be inspected, thereby, the scattering light of the foreign article is detected with a high illuminance. Even a minute foreign matter can be detected well.

Title: Multi-layer buildup welding method for high hardness metal
Inventor: ASHIDA TOSHIYUKI
IPC: B23K9/04
Filed: 1991-06-25
Abstract: PURPOSE:To execute buildup welding of a metal whose hardness is higher than conventional to the surface of a base metal more thickly than conventional. CONSTITUTION:The heat input quantity J in the course of welding, calculated by the heat input quantity (J)=60XIXE/v [(where) J: the heat input quantity (J/cm), E: an arc voltage (V), I: a welding current (A), v: a welding speed (cm/min)] is limited to a range of 2000-6000J/cm, and also, a welding condition is adjusted so that an interlayer temperature in the course of welding always does not rise of >=300 deg.C. By this condition, many minute cracks being orthogonal to the bead direction are dispersed and generated uniformly in the bead of a welded metal. Since many minute cracks are dispersed, a residual stress existing in the whole build-up layer is nearly released. Accordingly, such a large crack as a part of the bead pees and falls off is not generated.

IPC: H05K3/06
Filed: 1988-07-22
Abstract: PURPOSE:To form a fine pattern by using an electrodeposition type UV resist as an etching resist. CONSTITUTION:A hole 3 is made in a copper-clad laminating board on which a copper foil 2 is laminated on a base material 1 and a catalyst 4 is filled in the wall face of the hole. Then, an electrodeposition type UV resist is deposited onto the whole surface including side face parts facing to the hole 3 of a copper foil 2 to form an electrodeposition type UV resist film 5. An electrodeposition type UV resist film 5' is formed into a prescribed pattern by exposure and development. Subsequently, a copper foil 2' is formed into the prescribed pattern by using an etchant which does not dissolve the catalyst 4. Then, the film 5' is removed after being dissolved. A solder-resist film 6 which is proof against plating is formed on the surface other than the hole 3 and a through hole land part. Further, a chemical copper-plating film 7 is formed in the hole 3 and at the through hole land. As this approach makes it possible to form a fine pattern and makes a difference between the diameter of land in the through hole part and the diameter of the hole small, a packaging density of a printed wiring board is improved exceedingly.

Filed: 1991-07-23
Abstract: PURPOSE:To improve positioning precision in a state that a main spindle is brought into a stop by providing a control means to vary the voltage of a speed command only during the stop of the main spindle. CONSTITUTION:During a normal turning machining mode wherein no signal is outputted during a stop and a C-axis control movement mode, a level change- over switch 13 outputs a speed command signal to a D/A converter 15 as it is in a state shown by a solid line. However, in the case of a C-axis control stop mode wherein a signal is outputted during a stop, the contact piece of the level change-over switch 13 is connected, as shown by a dotted line, to a contact, and the level of a speed command signal is increased through a level regulator 14 and outputted to the D/A converter 15. In this case, in a main spindle control device 2, a signal during a stop is inputted in a similar manner described above to a digital speed controller 23 and a speed computer 25, where a range of control computation is switched and coded to the level of a speed command signal from the D/A converter. As noted above, during a C-axis control mode, a signal voltage level is increased to prevent the occurrence of disturbance by noise, and positioning precision in a state that a main spindle is brought into a stop is improved.
