Title: Power supply sequence circuit
Inventor: MATSUNAMI MASAHITO
IPC: H03K17/00
Filed: 1986-03-28
Abstract: PURPOSE:To design the titled circuit that output voltages of two voltage sources appear in a prescribed order without malfunction by providing a constant volt age element connected between a voltage source and other terminal of a switching circuit and a capacitive element connected in parallel with the said voltage source. CONSTITUTION:When an input voltage +Vin is applied from the 1st voltage source 1, transistors (TRs) 17,18 (1st and 2nd switching circuits) keep respectively the off-state. When a negative voltage -Vin is fed from the 2nd voltage source 3 representing a negative polarity, the negative voltage is outputted from an output terminal 6 without any time delay. Since the TR 18 in the off-state is inverted into the on-state to bring the base voltage of the TR 17 to a low voltage, the TR 17 is inverted to the onstate and a positive voltage is outputted from an output terminal 4. Since a positive voltage with a delay time 1 is outputted from the negative voltage output due to a cause such as the switching delay of the TRs or the delay by each resistive element and a stray capacitance, an output voltage attended with a time delay is given between the output terminals 6 and 4 without failure independently of the order of voltage application from the 1st and 2nd voltage sources.

IPC: H01L21/304
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To remove a treating liquid adhered to a rear end of a substrate without increasing a total amount of gas supplied to an air knife, by increasably switching an amount of the gas flowing to a second main tube by a second flow switching means, and additionally supplying a reduced amount of the gas in the first tube to a second main tube. SOLUTION: A flow controller 4 receiving an OFF signal from a first sensor PS1 and an ON signal from a second sensor PS2 sets an opening/closing valve V11 to a closed state, an opening/closing valve V21 to an open state, and an opening/closing valve V22 to a closed state. As a result, a gas supplied from a gas supply source to a main supply tube and branched to a first main tube L1 is branched to a bypass tube L11, then again returned to the tube L1, and supplied to a first air knife AK1. Contrarily, a gas branched to a second main tube L2 side is supplied to a second air knife AK2 without branching to a bypass tube 21. Thus, splash of cleaning liquid scattered from a substrate W can be prevented from being invaded into the knife AK1.

Abstract: PURPOSE:To measure the distance from a short-distance object so as to make a self-standing unmanned vehicle stronger to physical impacts, by burying a transmitting loudspeaker and receiving microphone in the main body of the unmanned vehicle to a depth corresponding to the pulse width of an ultrasonic pulse. CONSTITUTION:Ultrasonic waves radiated from a buried transmitting loudspeaker A go to the outside through a space produced when the speaker A is buried and reflecting waves of the ultrasonic waves by means of outside objects are inputted in a receiving microphone B through a space produced when the microphone B is buried. Therefore, the propagating distance of the ultrasonic is made longer by the length of the space when compared with the case where the loudspeaker A and microphone B are fitted to the side wall of the unmanned vehicle and measurement of any short-distance objects becomes possible.
