A silicon wafer for an IGBT is produced by forming an ingot having an interstitial oxygen concentration [Oi] of not more than 7.0×1017 atoms/cm3 by the Czochralski method; doping phosphorus in the ingot by neutron beam irradiation to the ingot; slicing a wafer from the ingot; performing annealing of the wafer in an oxidizing atmosphere containing at least oxygen at a temperature satisfying a predetermined formula; and forming a polysilicon layer or a strained layer on one side of the wafer.

摘要:
A first bearing member and a second bearing member fit in a first side and a second side of a rotating shaft in the axial direction, respectively. The first bearing member is held by a supporting portion provided in a casing on a side corresponding to an emplacing member of an image carrier drum. The second bearing member is held by fitting in a fit-in portion from inside. A wall surface that regulates a charging roller in a longitudinal direction is formed on the second bearing member to protrude from a wall surface rotatably and pivotally supporting the charging roller.

A pair of distance measurement sensors provided at different heights measures distances to an obstruction. When the measured distances are shorter than a threshold distance, the height of the vehicle is found based on the measured distances. When the height of the vehicle is found greater than a threshold height, the existence of the obstruction is reported to the driver. When the height of the vehicle is found smaller than the threshold height, on the other hand, a change in obstruction height is found and compared with a threshold. When the change in obstruction height is greater than the threshold, the existence of the obstruction is reported to the driver since the height is determined to be an unreliable result of computation.

When a conventional semiconductor container opening/closing apparatus opens a lid of a semiconductor container, foreign particles enter into the container from outside through a gap between the container and a wall surface of the container opening/closing apparatus and adhere to a wafer in the container. A method is provided to reduce the number of foreign particles adhering to the wafer by preventing foreign particles from entering into the container at the time of opening the container by the opening/closing apparatus. To achieve this, a velocity-differential pressure ratio obtained by dividing the maximum velocity at the time of opening the lid of the container in a vertical direction to an opening of the container, by the differential pressure between the inside pressure and the outside pressure of said semiconductor manufacturing apparatus, is set to be 0.06 ((m/s) Pa) or less.
摘要:
During a period until a subject vehicle stops to go back for being parked, detection distance data items and advance distance data items are obtained by using an ultrasonic sensor and a speed sensor. These data items are stored with both the data items mutually associated. The detection distance data item indicates a distance to a parked vehicle adjacent to the subject vehicle and the advance distance data item indicates a distance in which the subject vehicle advances. When computing a size of the parked vehicle from the advance distance data items, the size of the parked vehicle is determined to be shorter than an aggregated distance corresponding to the advance distance data items. This enables the determined size of the parked vehicle to approximate an actual size of the parked vehicle.

A communications system in a first vehicle sends departing information indicating that the first vehicle is about to depart from a parking space along with the vehicle information of the first vehicle when a door is unlocked, a key is inserted, and an engine is started. When the sent departing information is received by a communications system in a different second vehicle that is searching a parking space, the sent vehicle information of the first vehicle is shown in a display device in the second vehicle. The vehicle information includes the number of the license plate, the vehicle kind, the vehicle color, and the vehicle class. The driver of the second vehicle can easily determine whether a nearby vehicle where an occupant is present is the first vehicle that sends the departing information.

A calculator calculates an approximate value of a function Y=log (1+e−x) using input data x. In the calculator, a decoder outputs m-bit data that represents a value corresponding to the slope of a straight line, and further outputs intercept data of the straight line. The straight line interpolates the function Y=log (1+e−x) for an interval that includes the input data x as an X-value, and has a slope of −2n. The intercept data represents Y-intercept of the straight line. A shifter shifts the input data x by |n| bits based on the m-bit data, and provides the resultant value as first term data. An adder generates the sum of the first term data and the intercept data, and outputs the generated sum as an approximate value of the function log Y=(1+e−x)

摘要:
A front center opening can be opened and closed by a zip fastener. A hook assembly joins upper ends of the front center opening in a separable way and adjusts a waist size of pants within a fixed range. An adjusting cloth is sewed between one of fastener tapes of the zip fastener and an outer cloth of the front center opening. The adjusting cloth has an overlap to provide an extra length on the waist size of the pants. The hook assembly adjusts the waist size of the pants so as to fit a waist size of a user. The overlap of the adjusting cloth is extended in a specified manner so as to adjust a size of the pants corresponding to a portion lower than the waist of the user.
