Title: Motor drive controller
Inventor: YANASE MASAO
IPC: H02P1/16
Filed: 1985-01-14
Abstract: PURPOSE:To prevent the possibility of a damage due to an unexpected start by intermittently rotating a drive motor before the motor is started to a continuous rotation. CONSTITUTION:When the temperature of a fixing unit is raised the some degree after a power main switch is closed, a drive motor is intermittently operated. When the intermittent operation is completed, the motor is started to be rotated for a while to equalize the surface temperature of a fixing roller and to equalize the state of the surface of a photosensitive drum. Thus, the possibility of a damage upon starting not prenotified in case before the rotation can be reduced as low as possible.

Title: Gap detecting device
Inventor: HAZAMA JIYUNJI
IPC: G01B11/14
Filed: 1983-01-14
Abstract: PURPOSE:To detect the gap between two flat plates highly accurately, by judging the output sequence of detected image state signals of first and second luminous fluxes, whose images are formed on the two flat plates, which are separated by a specified interval in approximately the vertical direction, thereby determining the gap between the two flat plates. CONSTITUTION:When an objective lens is moved downward, the image of a first luminous flux BW is formed on a wafer W. The image is detected, and a position data S2 is outputted at a position P1 of the objective lens. The position P1 is stored in a microcomputer. A position P2 associated with the image of a second luminous flux BM is likewise stored. Then, the objective lens is moved upward, and positions P3 and P4 associated with the images of the luminous fluxes on a reflecting part 42 of a mask M are stored. Based on the output sequence of the positions P1-P4, the fact that a distance (g) between the image points of the luminous fluxes BM and BW is larger than a gap (d) between the mask M and the wafer W is judged. A value (g-d) is computed from the positions P1 and P3, and the gap (d) is determined. When g<d, the value is determined by the same way. Even though the gap between the two flat planes is minute, the gap can be detected highly accurately.

Filed: 1993-01-13
Abstract: PURPOSE:To shorten an erasure time in the whole of one chip by providing a circuit capable of simultaneously selecting plural word lines and digit lines respectively and the simultaneous writing function and the collating function of an expected value on a selected memory cell. CONSTITUTION:A plural word line(WL)/digit line(DL) selection signals C are set to H at the time of reading normal data. For example, when all of the WL selection signals A1, A2 and the DL selection signals B1, B2 are made the H, the WLW3 and the DLD3 are selected, and thus, one piece of memory cell 4 is selected, and the data with only one bit is read. The signals C are set to an L level at the time of writing before erasure and collating the expected value of the data written in the cell 4. Thus, for example, when all of the signals A1, A2 and the B1, B2 are made the H, the lines W1, W3 are selected simultaneously. Similarly, the lines D1, D3 are selected simultaneously as well. Thus, four pieces of cells 4 are selected simultaneously, and the expected data are written by a write circuit 6 simultaneously. Further, the collation is performed simultaneously through a collation circuit 5 as well.

Abstract: PURPOSE:To inflict no damage to a user of an elevator even if a cooling device gets out of order by diagnosing the operating conditions of a d.c. reactor and the cooling device according to contact signals of a temperature detector and the cooling device and conducting the optimum operation control according to the diagnosis result. CONSTITUTION:A cooling fan 4b of a d.c. reactor 4 is always operated during the operation of an elevator to cool a coil 4a.

That is, according to a signal output from a centrifugal contact 4c, if the rotational frequency of the cooling fan 4b is lower than a designated rotational frequency, the abnormality of the cooling fan is determined, and the running elevator is stopped at the nearest floor. If the normal operation of the cooling fan 4b is determined, subsequently it is determined whether the temperature of the coil 4a is normal or not. If an output signal of a temperature detector 4d shows a temperature higher than a designated temperature, it is determined that the temperature of the coil 4a is abnormal, and the operation of the elevator is prohibited.
