Title: Analog optical transmission system
Inventor: IMASHO YOSHIHIRO
IPC: H04B3/46
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To detect a fault of an optical fiber through the supervision of a master set only in the optical transmission system where the master set and a slave set make 2-way communication of an analog optical signal through two optical fiber paths. SOLUTION: An oscillator 2 of a master set T1 oscillates a monitor signal with a frequency different from that of an RF multiplex signal a1, a synthesis means 4 synthesizes both the signals, a light emission means 5 transmits a synthesis signal to a light receiving means 21 of a slave set T2 through an outgoing optical fiber F1. A filter means B4 of the slave set T2 separates the monitor signal from the received optical signal, a synthesis means 27 synthesizes the separated signal with the RF multiplex signal b1 and a light emitting means 28 transmits the synthesis signal to a light receiving means 11 of the master set T1 through an incoming optical fiber F2 as an optical signal whose mean optical output is constant.  A detection means 12 of the master set T1 detects a mean optical power of the received optical signal, a filter means B2 separates the monitor signal from the optical signal and a detection means 15 detects a level of the separated signal.

Then, the 2nd gate and 1st gate are opened for the same period, and the otput of the amplifier 8 is inverted in polarity by a subtractor 15 and then integrated. Lastly, a detection display gate 11 is opened for a time shorter than the period of high-voltage pulse appliecation to display the contents of the integrator 10 on a detection meter 12. Thus, DC drift, temperature drift and malfunction due to the commercial frequency are eliminated.

IPC: H01L21/8249
Filed: 1991-06-24
Abstract: PURPOSE:To obtain a Bi-CMOS device having high speed characteristics and high reliability, and its manufacturing method wherein the number of manufacturing processes is reduced. CONSTITUTION:A nitride insulating film 32 is formed on an SiO2 film 30 in a bipolar region and a gate oxide film 31 in an MOS region. Thereby the gate oxide film 31 is protected by the nitride insulating film 32, when the emitter window of a bipolar transistor is formed, and when dip etching is performed before a poly-Si film 34 is deposited. Hence the poly-Si film 34 turning to the emitter electrode of the bipolar transistor and the gate electrode of an MOS transistor is simultaneously formed without deteriorating the gate oxide film 31 of the MOS transistor. Thereby the number of processes can be reduced, and punch through effect of the gate oxide film due to diffusion of impurities can be prevented.

Filed: 1993-06-22
Abstract: PURPOSE:To provide a staff by which a surveying operation such as a leveling operation or the like can be performed automatically even when a measuring operator does not collimate and interpret a graduation. CONSTITUTION:A graduation means A1 which is arranged in the lengthwise direction of a staff 1 is provided with a reference light-emitting element a01 which emits light at a reference cycle and with light-emitting elements a11, a21, a31, a41, for graduations, which emit light at two or more cycles which are different from the reference cycle. Since the arrangement of the cycles at which the light-emitting elements for the graduation emit the light is different among all graduation means, a position on a staff can be known when a graduation means which is observer by an electronic level is specified, and a leveling operation or the like can be performed automatically. Thereby, even when an operator does not collimate the staff, a surveying operation can be performed automatically even in a dark atmosphere.
