Title: Substrate cleaning device and method
Inventor: TANIGUCHI SATOSHI
IPC: H01L21/304
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To clean a substrate sufficiently without increasing a treatment tact of the substrate. SOLUTION: This substrate cleaning device is provided with a turn-on part 20 turning the substrate on, a brushing part 30 for supplying cleaning water on the main surface of the turned-on substrate, so as to perform brush-cleaning or the like and a pay-out part 40 for taking-out the substrate after cleaning. In the brushing part 30, the first to third cleaning processes reciprocating the substrate are performed. In the second time cleaning process in the return direction, a first roller brush 31 rises from the first abutting position to a side position, so as to perform cleaning only with a second roller brush 32. Accordingly, in the second time cleaning process, a transfer process of the substrate WF can be shortened, and a treatment tact can be improved without speeding up a transfer speed of the substrate WF.  Moreover, in this second time cleaning process, a first roller brush 31 relatively liable to be contaminated does not come in contact with the substrate WF, so as to make the cleaning of the substrate WF effective.

Title: Fatigue test monitoring device
Inventor: MOTOYAMA NARIKIYO
IPC: G01N3/32
Filed: 1987-01-13
Abstract: PURPOSE:To immediately stop a fatigue test at a measurement point to which a fatigue limit is attained and to obtain accurate data by observing the transition of strain at each measurement point of a body to be inspected and generating a warning signal when a specific singular transition state at the time of the fatigue limit is observed. CONSTITUTION:A data processing means M15 detects the transition of the dynamic strain which a stress generating means M12 controlled by a stress control means M13 makes the body M11 to be inspected generates through a stress measuring means M14 arranged at respective measurement points. When the body M11 to be inspected is fatigued and a warning M16 observes that the transition of the strain detected by this data processing means M15 is in the specific singular transition state at the time of the fatigue limit, this warning means M16 outputs the warning signal. Consequently, a proper countermeasure is taken before the measurement point to which the fatigued limit is attained exerts adverse influence upon other measurement points. This warning signal may be used as a trigger for countermeasure which stops the control of the stress control means 13 over the stress generating means M12.

Title: Control method for fan motor
Inventor: WADA YOSHIHARU
IPC: G03G21/00
Filed: 1987-01-13
Abstract: PURPOSE:To drive a cooling fan by a single power supply by continuously running the cooling fan at the time of forming an image, and at the time of forming non-image, turning on and off power supply to the cooling fan to execute intermittent running of the cooling fan. CONSTITUTION:When a main motor 55 is on during the image formation, an 'L0' level signal is inputted to a binary counter 52. Since the binary counter 52 is set up under said state, the 'L0' level signal is inputted to a fan motor driving circuit 53 and a fan motor is continuously driven. Since the main motor is off during waiting (non-image formation), the 'L0' level signal is not inputted to the reset terminal of the binary counter 52 and respective signals 'Q1', 'Q2',  OR', 'AND' based upon the reference frequency signal from an oscillator 51 are inputted to the circuit 53, so that the fan motor 55 is intermittently driven by repeating ON and OFF. Since the cooling fan is rotated at a single rotational frequency by a single power supply, plural power supplies are not required and the size and cost of the device can be reduced.
