Title: Developing device
Inventor: SAKAMOTO ISAO
IPC: G03F7/30
Filed: 1982-09-10
Abstract: PURPOSE:To prevent stains on the reverse side or underside of the material to be developed, by installing a nozzle for spraying a rinse soln. from the central side toward the outer border of the underside of said material below the chuck of a spinner. CONSTITUTION:A processing soln. 12 consisting of a developing soln. and a positive resist dissolved in said soln. is moved to the outer border of a wafer 2 and scattered arund by the centrifugal force. At that time, since the rotation of the spinner chuck 1 is slow and said force is small, the processing soln. 12 tnds to turn around the outer end of the wafer 2 to its underside. But, the rinse soln. 9 is jetted strongly against said outer end, so the soln. 9 does not turn around the end to the underside, and scatters around released from the outer end. Accordingly, the reverse side of the wafer is prevented form being stained with the soln. 12 during the development processing, hence trouble, such as staining of conveying systems in the following step, incapability of vacuum attraction holding of the wafer, or inferior alignment, can be prevented.

Title: Constant speed running control method for vehicle
Inventor: KAWANO ATSUHIRO
IPC: F02D29/02
Filed: 1989-06-20
Abstract: PURPOSE:To enhance the reliability of the control by implementing the operation of opening or closing a throttle valve at a constant speed when the voltage value as output from a throttle sensor indicates abnormality, and by continuing the car speed control by the use of a pseudo car speed if this output voltage value has returned to the control value with this implementation. CONSTITUTION:A throttle valve 6 provided in a suction passage 10a is opened or closed by a drive motor 5, which his controlled by a controller 3 on the basis of the car operating condition. At this time, the voltage signal emitted by the throttle sensor 14 is sampled at certain intervals to permit the sensor 14 to judge abnormality on the basis of deviation of the present voltage value from the previous voltage value. In the even of abnormality, the throttle valve 6 is opened or closed at a certain constant speed. If the output voltage from the throttle sensor 14 returns to the normal value before a certain period of time has elapsed since the abnormality was sensed, the car speed control is continued by the use of a pseudo voltage value anticipated from the previous voltage value and also the value before it, and if not returned, it is judged that the car speed is uncontrollable.

Abstract: PROBLEM TO BE SOLVED: To recognize a consumption state of a machine glazed paper without operation concerning detection of the machine glazed paper even if a set attitude of a printer main body is changed. SOLUTION: In this printer, a printer main body 1 allowing a change of its set attitude has a machine glazed paper storage part 9 with a placing face 17 supporting the peripheral face of the machine glazed paper 8 against the weight of the machine glazed paper 8 itself regardless of the change of the set attitude of the printer main body 1, while a machine glazed paper displacement detection means detects displacement of a center part caused by the weight of the machine glazed paper 8 itself regardless of the change of the set attitude of the printer main body 1.  Accordingly, when a winding diameter of the machine glazed paper 8 becomes small by consumption, the center part of the machine glazed paper 8 supported on the placing face 17 of the machine glazed paper storage part 9 is displaced to the vertical direction to which the weight of the machine glazed paper 8 itself acts regardless of the set attitude of the printer main body 1. The machine glazed paper displacement detection means detects the displacement to recognize a consumption state of the machine glazed paper 8. Even if the set attitude of the printer main body 1 is changed, no operation concerning the detection of the machine glazed paper 8 can be required.
