Patent JP-H04255437-A (JP)
Title: Stator for motor
Inventor: HAZUMI KOUICHI
IPC: H02K1/16
Filed: 1991-02-06
Abstract: PURPOSE:To reduce flux leakage of the stator core of servo motor, for example, and to punch out laminate boards with high yield. CONSTITUTION:Bridge part (2) at the pole part (12) of a laminate board (11) is separated for every plurality of pole parts (12) thus forming a gap (3). The laminate boards (11) are then laminated while shifting every layer so that the bridge part (2) and the gap (3) are arranged alternately. A field part such as a coil and a magnet is arranged in a field groove (13). The gap (3) cuts off the leakage flux path of each layer thus reducing reactive flux. Furthermore, yield of material is increased because the laminate boards (11) are punched while being combined appropriately.

IPC: H01L29/74
Filed: 1989-02-15
Abstract: PURPOSE:To sufficiently recover a lifetime and to prevent an ON voltage from being increased by a method wherein an oxide film, on one face, to be used as a mask is removed selectively, also an oxide film on the other face is removed and phosphorus is deposited. CONSTITUTION:An oxide film 2 of a silicon wafer 1 of a P-n-P structure is formed again; a window is opened in an oxide film 2 on the side of one main face by using a photolithographic technique; an oxide film 2 on the side of the other main face is removed. In order to form N-type semiconductor regions in P-type semiconductor regions on the two main faces, phosphorus is diffused including a driving operation of the phosphorus in such a way that the phosphorus having surface concentration of 10<21>/cm<2> or higher is deposited and that the surface concentration after the driving operation is 10<21>/cm<2> or higher; in addition, a phosphorus diffusion layer on the side of the other main face is removed by a lapping operation or the like. Thereby, a lifetime of the silicon wafer 1 after the phosphorus has been driven is recovered to a level identical to an initial wafer; it is possible to prevent an ON voltage from being increased.

Abstract: PURPOSE:To make it possible to perform processing characterized by high throughputs, by providing a conveying mechanism comprising a conveying part which conveys bodies under processing into a heat treating mechanism and a standby part which temporarily holds the bodies under processing. CONSTITUTION:Four juxtaposed hot plates 110, 111, 112 and 113 are provided in a heat-treating mechanism 115 and a semiconductor wafer 114 is heat-treated there.

Title: Malfunction preventing device for control circuit
Inventor: AKIYAMA TAMON
IPC: H04N5/60
Filed: 1979-03-27
Abstract: PURPOSE:To prevent the malfunction of the control circuit by detecting the AC signals of different frequencies given and then giving the control to other circuit with the detection output. CONSTITUTION:The detector of the control signal for the multiple voice broadcasting is supplied to terminal 10 in the TV picture receiver. The AC control signals for the stereo and multiple voice broadcasting each are applied to DC signal generator circuits 40 and 50 through filters 20 and 30. At the stereo broadcasting time, the output of circuit 40 drives transistor TrQ61 of detection circuit 60, and then the detection signal of stereo broadcast reception switching is obtained from terminal 80 and via TrQ71 and Q72. At the same time, TrQ1 is made to conduct along with light emitting diode L1 lit up to give the lamp display indicating the stereo broadcasting on the air. In this instant, the collector of TrQ1 features nearly the earth potential. With this earth potential, the base potential is clamped via diode D3 for voice multiple broadcasting control DC signal amplifier TrQ63. As a result, the malfunction caused by the noise or the like can be prevented for the multiple voice broadcasting. At the multiple voice broadcasting time, the malfunction is prevented for the stereo broadcasting in the same way.

IPC: G01N25/02
Filed: 1981-03-12
Abstract: PURPOSE: To properly stabilize the operation of blast furnace by properly controlling the distribution of gas flow in the blast furnace by a method in which the distribution condition of gas flow in a blast furnace is detected from the last observed data on the distributions of gas components and temperature, and on the basis of the results, the charging distribution of iron ore, coke, etc., is controlled.  
     CONSTITUTION: The distribution conditions of gas components and temperature inside a blast furnace 21 are measured by a measurer 22, e.g., shaft sonde, furnace top fixed temperature sonde, etc., and processed by a process computer 23. An information of gas flow distribution, temporarily stored in a memory 24, is sent to a master computer 26, stored in a large-capacity memory, and then displayed on a displayer 28. In this case, data on past gas flows are divided into central flow group, peripheral flow group, and intermediate flow group, a function for grouping each of the gas flow groups is prepared from the observed data by a discriminating function method, and the distribution of gas flow is detected from the positonal relation of a function by the observed data at the present time. From the results, the distribution of charged raw materials, e.g., iron ore, coke, etc., is adjusted to normalize the distribution of gas flow in the blast furnace. Thus, the operation of the blast furnace can be stabilized.

IPC: G06T19/00
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To keep the form feature of an original mesh and to optimize and simplify a polygon mesh by reducing a redundant polygon, evaluating a characteristic ridge line with an approximate minimum curvature, integrating the characteristic ridge lines with each other by means of the degeneration of the ridge lines and obtaining an approximate polygon mesh. SOLUTION: A characteristic ridge line is degenerated (S109). It is judged whether the ridge line of a degeneration object is eliminated or not (S10). When the ridge line is detected, it returns to a processing process (S108) and a processing is executed. The processing is repeated until the characteristic ridge line being the object of degeneration cannot be detected. When the ridge line of the degeneration object is eliminated, it is advanced to the next processing process. It is judged whether the degeneration of the ridge line is not applied in processing processes (S106) and (S109), namely, whether the degeneration of the ridge line is not executed even once or not (S111). In the case of YES, the processing terminates (S112).  In the other case, it returns to an initial processing process (S101) and the processings are repeated until the judgment of a processing process (S111) finally becomes YES.
