Title: Optical switch for optical network
Inventor: OOTE AKIRA
IPC: H04B10/00
Filed: 1984-03-09
Abstract: PURPOSE:To increase a switch speed by putting an optical switch in repeat operation with a control voltage when the operation of each station is normal, and lowering the control voltage to zero and by-passing all outputs from leading stations during abnormal operation. CONSTITUTION:The transmission part 1012 of a station 101 outputs a signal from an LED to an optical switch 91. A control part 1013 applies the control voltage to the electrode of the optical switch 91. When respective stations are in normal operation, optical switches 91-93 lead all light beams from leading stations to receivers 1013 with the control voltage from a control part 1013 and also lead all light beams from transmission parts 1012 to following stations. When some station operates abnormally, the voltage from its control part 1013 drops to 0V and light from the leading station is all guided to the following station. Consequently, even if one station is shut down, all signals by-pass the station with high efficiency, so station intervals are increased. Further, optical network switches which has a fast switch speed and small insertion loss are realized.

Title: Manufacture of crystal oscillator
Inventor: TANAKA MASAKO
IPC: H01L21/3065
Filed: 1995-03-06
Abstract: PURPOSE: To reduce the influence of the anisotropy of crystal and to realize the smooth working of a crystal surface by executing reactive ion etching for circulating etching gas on a crystal substrate and impressing voltage. CONSTITUTION: In the manufacturing method of a crystal oscillator having the etching process of the crystal substrate, a reactive ion etching process for circulating etching gas on the crystal substrate and applying voltage is given as an etching process. In such a case, it is desirable to smooth the crystal oscillator to a desired smoothing degree before and after reactive etching. It is desirable to use hydrocarbon fluoride as etching gas, and it is more desirable to use CHF3 -CF4 or C2 F6 individually or by mixing them. Thus, etching working without crystal axis dependency (without anisotropy) can be realized, and the precision of an etching shape can be improved.

When a circuit board 3 and the chip 12 are opposed at an interval, a two visional position detecting optical system 27 is actuated to detect the relative position of the board 3 and the chip 12. Then, a chip side shutter 31 and a board side shutter 32 alternately open and close so that a control part may take the picture images of the board 3 and the chip 12 to measure the slippage amount of both elements. Consequently, the shift correcting signals are inputted from the control part to a board loading stage and a bonding head 7 so as to perform the alignment and mounting process of the board 3 and the chip 12.

Title: Dialing circuit
Inventor: KIKUCHI TORU
IPC: H04M1/31
Filed: 1987-02-27
Abstract: PURPOSE:To absorb a spark at dialing with inexpensive constitution by connecting a varistor in parallel with a relay contact passing through a dial pulse signal. CONSTITUTION:When a dial number is inputted through the operation of a dial button of a pushbutton telephone set, a control section drives a relay Di in response to the dial number to interrupt a DC loop by turning on/off the contact di and generates a dial pulse to send it to a station exchange. In this case, the spark generated by on/off of the relay contact Di is absorbed by a nonlinear resistance characteristic of a varistor V and since it is not required to control the varistor V by a control section, the control section is realized with simple constitution.

Abstract: PROBLEM TO BE SOLVED: To easily match a body to be measured with a measurement area for achieving an accurate measurement and to improve the reliability, by providing a case for accommodating an optical system and a rotary mechanism for rotating the case with the focusing position of light for measurement as the center. SOLUTION: A light source optical system and a light reception optical system that and incorporated into a case 1 are moved in one piece in X, Y, and Z directions by operating an XYZ stage 49 and a rotary mechanism 40 is rotated and operated and the light source optical system and a light reception optical system 30 are rotated in one piece with a focusing position S of the light source optical system as the center, and a body 4 to be measured is aligned to the same position as the focusing position S of the light source optical system. Since the rotary center of the rotary mechanism 40 is matched with the focusing position S that is a measurement point, the body 4 to be measured cannot deviate from the focusing position S even if the rotary mechanism 40 is operated and the case 1 is rotated. Therefore, the light axis of the light source optical system and the inclination of the traveling direction of the body 4 to be measured can be adjusted only by adjusting the rotary mechanism 40.
