Patent JP-H03109751-A (JP)
Title: Rotation and treatment of wafer
Inventor: SUZUKI SHINJI
IPC: H01L21/027
Filed: 1989-09-25
Abstract: PURPOSE:To improve yield of a product by specifying the relationship among a rotation angle of a wafer which is generated when loading or unloading the wafer, a rotation angle of the wafer which is produced when treating the water, and the angle formed by the loading/unloading direction on the loading side wafer cassette and the loading/unloading direction of the wafer cassette on the unloading side. CONSTITUTION:When a rotation angle of a wafer 1 which is produced when loading or unloading the wafer 1 is set to theta1, a rotation angle of the wafer 1 which is produced when treating the wafer 1 is set to theta2, and an angle formed by the loading/unloading direction of a wafer cassette 20 on the loading side and that of a wafer cassette 21 on the unloading side is set to theta3, each theta1, theta2, and theta3 is set so that an expression theta1+theta2=360 deg.Xn+theta3 (n: integer) may be satisfied. Thus, the wafer 1 is stored in the wafer cassette 21 on the unloading side at the same position as in the wafer cassette 20 on the loading side after the treatment is completed, thus preventing the wafer 1 from hitting against the wall surface of the wafer cassette and a resist from being scattered. This will lead to an improved yield.

Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To attain simple recording by providing a means recording a voice during a speech between an opposite subscriber of a side of an exchange and an externally mounted telephone set. SOLUTION: While an external telephone set 7 makes a speech with an opposite subscriber at a side of an exchange 6 via a line changeover switch 5 not in operation, when the speech content is recorded simply, the external telephone set 7 enters a predetermined specific selection signal. Then a selection signal detection section 1 detects the entered specific selection signal and analyzes it and discriminates that the signal indicates a recording request, then it is informed to a control section 3, then the control section 3 sends a voice recording request signal to a voice recording section 2. The voice recording section 2 receiving the voice recording request signal receives a channel between the externally mounted telephone set 7 and the line changeover switch 5 with high impedance and records the voice during speed as a monitor signal.  When the automatic answering recording of the voice is desired, the line is switched similarly to the case of facsimile reception.

Title: Phase synchronizing circuit
Inventor: MURATA KOICHI
IPC: H01L31/10
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To realize a high speed, low dissipation power and small number of elements, by constituting an oscillator by using a resonance tunnel diode, connecting a photodiode to the tunnel diode in parallel, and injection locking it. SOLUTION: In the phase synchronizing circuit PS1, a light signal is inputted to a photodiode PD, and a phase-synchronized electric signal is outputted from a connecting point of a transmission line TD to a resonance tunnel diode RTD. For example, if a light input signal having a frequency near 1/4γ Hz is incident on the photodiode PD, the photodiode PD generates current in response to its light input power. The generated current is injected in the diode RTD, a circuit oscillated in the state that the light is not incident is injection locked, and the phase of the oscillator is locked to a phase of the light signal externally incident. A clock signal phase-synchronized with the external input signal can be obtained.
