Provided is a blank structure for a ring member of a bearing in which a cut target surface after stainless steel is forged has uniform surface characteristics, and highly accurate cutting processing is enabled. A blank (10), which is processed to an outer race (2) and an inner race (3) of a bearing, includes: a cylindrical portion (11, 12) formed by forging a stainless-steel material, and having an inner circumferential surface (11a, 12a) and an outer circumferential surface (11b, 12b) entirely being surface eutectic carbides fragmented beds; and a clamp portion (13) provided to one end portion side of the cylindrical portion (11, 12).

An image forming apparatus is provided with a pressing roller for pressing a sheet at the time of a fixing operation; a fixing roller having a hollow portion, facing the pressing roller, rising in temperature by being heated, and fixing a developer to the sheet by sandwiching the sheet between the fixing roller and the pressing roller; and induction heating coils including a center-section coil and an end-section coil, and arranged inside the fixing roller in an axial direction so as to leave a space between the center-section coil and the end-section coil, the space being adjusted so that the temperature of one surface of the fixing roller, the one surface opposing the space, is not higher than the temperatures of the other surface of the fixing roller, the other surface opposing central portions of the coils.

An apparatus connection interface remarkably reduces the processing load of the controller. The apparatus connection interface includes a pair of connectors including a first connector and a second connector having respective signal transmission terminals for connecting a plurality of apparatus to be controlled in series to form an annular signal transmission line so as to circulate and transmit a condition confirming signal for confirming the condition of the apparatus to be controlled and, at the same time, circulate and transmit a condition notifying signal for notifying the condition of the individual apparatus to be controlled by way of the formed signal transmission line.

A printer controller 41 sets compensation values, representing the positional deviations of LED array chips 31, in a delay circuit section 68 via shift register 61 and a latch circuit 63. The shift register 69 sequentially acquires bit map data from the printer controller 41, and supplies the acquired bit map data to an AND gate 66 through the latch circuit 62. Upon receiving a strobe signal from the printer controller 41, the delay circuit section 68 supplies the received strobe signal to the AND gate 66 after a delay time corresponding to a preset compensation value has lapsed. The AND gate 66 generates drive signals each being the logical product of the input bit map data and the strobe signal, and supplies them to the LED array chips 31 through a buffer 67. The LED array chips 31 make LEDs emit light at the timings corresponding to the positional deviations so that images are formed without a positional deviation. At least one of the LED array chips is unaligned with adjacent ones of the LED array chips and preset compensation values are obtained by interpolation based on detected positional deviations of sampled ones of the LED array chips.
摘要:
A system for measuring a traveling direction of a vehicle includes a geomagnetic sensor and a gyro sensor. The system utilizes first and second indicies for deriving the vehicle traveling direction. The first index is indicative of disturbance of a geomagnetic field on a short interval basis, and the second index is indicative of disturbance of the geomagnetic field on a long interval basis. The system further utilizes a correction value indicative of a drift error caused by the gyro sensor for deriving the vehicle traveling direction. The system varies a rate of dependence upon an output of the geomagnetic sensor and an output of the gyro sensor based on the first and second indicies and the correction value when calculating the vehicle traveling direction.
