Title: Cup type grindstone
Inventor: KIKUMA RYOZO
IPC: B24D7/00
Filed: 1986-10-06
Abstract: PURPOSE:To prevent a workpiece to be partially overheated, by effecting grinding to made a highly accurate finished surface by changing a width of an abrasive grain layer over a circumferential direction and improving application of grinding lubricant by changing a width of an abrasive grain layer over a circumferential direction. CONSTITUTION:An abrasive grain layer 11 formed at the lower end surface of a grindstone base metal 10 has an inner circumferential edge 11A made to a circular shape, while its outer circumferential edge 11B is formed to have an elliptic shape. The abrasive grain layer 11 is such that its width is gradually changed between a maximum width W1 and a minimum width W2. When surface grinding is effected by a cup type grindstone of this arrangement, the outer circumferential edge 11b moves forwardly and backwardly at a tip portion in an grinding direction each time the grindstone is rotated so that it grinds the surface of a workpiece in its relatively wide region for grinding it to a gradually inclining surface. Therefore, accuracy of the finished surface is increased without remaining arc-shaped stripes. In addition, grinding lubricant is applied well by intermittently exposing a portion to be ground and partial overheating is prevented, whereby deterioration of the surface such as burning due to grinding can be prevented.

Title: Semiconductor device
Inventor: SADAMORI MASAAKI
IPC: H01L29/74
Filed: 1983-12-16
Abstract: PURPOSE:To prevent the generation of voids which would otherwise become gaps between the back of an element end and a substrate by a method wherein, in fixing a semiconductor element on the semiconductor element supporting substrate via Al-Si alloy and the like, using an Mo plate of relatively small diameter as the supporting substrate, its outer periphery is surrounded by a ringform polycrystalline Si frame. CONSTITUTION:A thyristor element 2 having the PNPN junction is adhered on the semiconductor element supporting substrate 10 made of Mo or the like with an Al-Si alloy thin film 3. Next, the side surface of the element 2 is etched with the mixed solution of nitric acid and hydrofluoric acid, thus producing an incline surface 2a in a bevel form. Thereafter, the uppermost layer of the element 2 is provided with a gate electrode 5 at the center, and an anode 4 is formed around it. In this construction, the substrate 10 is not made up of a single plate, but made up of a composite substrate by fitting a polycrystalline Si ring-form frame 7 in the outer periphery of the Mo plate 10 of relatively small diameter corresponding to the anode 4 via Al thin film 30. Such a manner does not allow an etchant to infiltrate into the end back of the element 2 at the time of bevel etching, thus preventing the generation of voids thereon.

Filed: 1987-09-22
Abstract: PURPOSE:To eliminate the need to adjust a variable resistor by completing zero/span adjustment only by setting an input signal to its upper-limit and lower-limit values and supplying a set signal and a start signal. CONSTITUTION:When the zero/span adjustment is performed, the analog input signal (a) is set to the lower-limit value first and a lower-limit value holding indication signal (e) is turned on to hold input data (b) in a lower-limit value holding register 5 as lower-limit value data (g) when the analog input signal (a) is at the lower-limit value. Then the input signal (a) is set to the upper-limit value, and an upper-limit value holding indication signal (d) is turned on to hold the input data (b) in an upper-limit value holding register 4 as upper-limit value data (f) when the input signal (a) is at the upper-limit value. Then the arithmetic start signal (j) is turned on to actuate a parameter arithmetic circuit 8. Consequently, the variable resistor need not be adjusted and the adjustment is easily automated.

Title: Method for detecting hot slab
Inventor: MARUI TOMOTAKA
IPC: G01V8/12
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To definitely detect the edge of a hot slab by positioning a detector so that the angle between the optical axis of the detector and the moving direction of a slab can become a prescribed value in the same vertical plane and detecting the radiant energy in the vertical plane. SOLUTION: Hot metal detectors HMD-1 to HMD-3 are positioned so that the angles between the optical axes 3 of the detectors and the moving direction of a slab 1 can become 40 deg.-85 deg. (preferably, 60 deg.) in the same vertical plane. As a result, the detecting error of the slab 1 can be reduced, because the emissivity of the end face 6 of the slab 1 increases because of scales falling down from the end face and the probability of the reflecting angle of the end face becoming coincident with the Brewster angle is high. When the slab 1 is transferred toward a roughening mill 10 from the downstream side, the detector HMD-1 detects the end face 6 of the slab 1 and, when the slab 1 is transferred to the upstream side through the mill 10, the detector HMD-3 detects the end face 6.  When the slab 1 is transferred toward the mill 10 from the upstream side, the detector HMD-2 detects the end face 6. The detectors HMD-1 to HMD-3 transmit their output signals to a process computer, etc., and the computer controls a prescribed process.
