Abstract: PURPOSE:To increase a wiring ratio by a method wherein a terminal of a small- scale macrocell existing in a terminal extension region is extended to the extension position and then the position of a disposed small-scale macrocell which has the connection relation with the small-scale macrocell is determined based on the position of the terminal after it is extended. CONSTITUTION:When a judging section 3 decides that a small-scale macrocell exists in a terminal extension region, a section 4 which determines the position to which a terminal is extended extends a terminal of the small-scale macrocell based on the extension position data of a first storage section 1. Based on the position to which the terminal of the small-scale macrocell has been extended by the section 4 and the data about terminal coordinates of each small-scale macrocell which is stored in a second storage section 2, a disposed cell position determining section 5 decides the position of a disposed small-scale macrocell which has the connection relation with the small-scale macrocell whose terminal has been extended.

Abstract: PROBLEM TO BE SOLVED: To realize a scanning electron microscope formed so that the position of a deflection supporting point of the electron beam always passes through the main surface position of an objective lens, even if the position of the lens main surface of the objective lens is changed. SOLUTION: A CPU 15 controls an objective lens drive circuit 13 through a D/A conversion unit 14, and when the strength of the excitation of an objective lens 5 is changed, the CPU 15 reads out the data of the deflection angle of deflecting coils 7, 8 corresponding to the strength of the excitation of the objective lens 5 from a memory 16.

Abstract: PROBLEM TO BE SOLVED: To improve the availability and throughput of the apparatus by automatically treating substrates remaining in a film forming chamber in the event of a trouble during automatically operating, after recovery from the trouble and then resuming the automatic operation. SOLUTION: After an operation ready mode, system proceeds to an in- operation mode 101 if no substrate remains in a film-forming chamber. If the substrate remains in the chamber, a message is indicated for the operator. If the operator selects the feed-in resume, system proceeds to the mode 101 with leaving the substrate in the chamber. The remaining substrate after proceeding to this mode 1010 is treated after being carried into a film-forming chamber. If the operator selects ejection, a film forming omit flag is added to the remaining substrate and this substrate is ejected. As required, a new substrate is inserted in the film-forming chamber and system proceeds to the in-operation mode 101.

Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To immediately operate a noise cancellor in a converged state, when a call from transmission/incoming call starts or when a busy mute is released and to satisfactorily maintain the quality of the call. SOLUTION: At the time of transmission/incoming call, a control circuit 22 sets only the noise cancellor 12 in an operation state when a call channel is established, unmutes transmission mute switch 16 and starts the take-in learning of peripheral noise. When a system becomes a call state, speech CODEC 11 is set in the operation state, and the call is started. The noise cancellor 12 is sufficiently converged at that time, and the satisfactory call can be execrated from call start time. The control circuit 22 transmits a mute equivalent signal from speech CODEC 11, and a system is returned to the transmission of a transmission speech signal in a normal level by an unmute operation. During that time, the noise cancellor 12 becomes an operation state and immediately executes a noise cancel operation in the converged state at the time of restoring to an unmute state.
