Title: Optical transmission system
Inventor: TSUKAGOSHI TAKASHI
IPC: H04B10/299
Filed: 1987-03-11
Abstract: PURPOSE:To detect all faults in a transmission line at a terminal station side by sending a fixed pattern other than all 1s as an AIS signal from an optical repeater, and sending an error in the transmission line to the succeeding station while being overlapped with a main signal. CONSTITUTION:After an optical input signal is converted into an electric signal by a photoelectric converting section 11 and outputted as a CMI signal 19 and a clock signal 20 and sent to a CMI decoding section 12, where the CMI signal is separated into a data signal 21, a clock signal 23, an error information signal 25, and a sub information signal 28. In this case, when the interruption of input signal is detected by a conversion section 11, selection circuits 13-1, 13-2 switch the data signal 21 into the fixed pattern 22 from a FF and the clock signal 23 into a clock signal 24 from the oscillator 14. Moreover, an error information signal 25 is sent as it is to a CMI coding section 16, superimposed on the main signal by using the violation of code rule and sent to the succeeding station.

Title: Ventilation fan interlocked with gas appliance
Inventor: KINOSHITA HIROSHI
IPC: F24F7/06
Filed: 1978-05-10
Abstract: PURPOSE: To prevent accident by providing a ventilation fan with an operating switch and a draft detecting switch and opening a gas duct open-close valve only  when the both switches are closed.  
     CONSTITUTION: With a ventilation fan operating switch 3 closed manually, a motor 6 rotates vanes 5 so that the air provided with velocity and pressure by the vanes 5 is exhausted. The wind pressure causes a shutter plate 11 rotatably fitted on a shutter shaft 10 to open in the direction of the arrows. Because a magnet 12 at the lower end of the plate 11 goes away from a draft detecting switch 13, the switch 13 closed. The closing of the switch 13-1 opens a gas duct open-close valve 7, a gas is fed to a gas appliance 4, and the appliance 4 is ready for use by the operation of an ignition control and the like.

Filed: 1978-05-09
Abstract: PURPOSE: To improve the maximum output and the efficiency of a thyrister converter by increasing the possible range of ignition angle of lead for the thyristor in the operation of the inverter.  
     CONSTITUTION: A circuit L on the AC side of a thyristor converter REC is provided with a transformer CT for detecting changes during commutation. The output of the transformer CT is sent to a commutation overlap angle detector 1 where the duration of a current change, namely, commutation overlap angle U, is calculated. The output signal of the detector, regulating the U, is compared by a device 2 for computing commutation marginal angle with a signal synchronous with AC current to the thyristor converter REC to determine a commutation marginal angle θ m .  The angle is compared by a minimum ignition angle of lead setting circuit 4 with  a proper set cummutation marginal angle θ s . In this manner, the minimum ignition  angle of lead β min   can be set so that the defference from the value (θm-θs)  may be minimized.

Title: Amplifier control circuit for magnetic recording/ reproucing device
Inventor: MIURA MASAMI
IPC: H03F3/72
Filed: 1990-03-06
Abstract: PURPOSE:To reduce power consumption related to a head amplifier by stopping the recording amplifier circuit of the head amplifier, at least, in a magnetic recording/ reproducing device by a recording stop signal impressed to a control terminal. CONSTITUTION:The head amplifier 10 consists of a reproducing amplifier 2, a recording amplifier 1, and an amplifier control circuit 11 to control the recording amplifier 1. At the time of recording, OV is impressed to the control terminal 5, and at the time of stopping the recording, 5V is impressed to it. First, in the case voltage impressed to the control terminal 5 is OV, since a current I5 does not flow, a constant current I2 flows to a transistor (TR) Q7, and distributed currents I41, I42 to I4m flow in the TRs Q81, Q82 to Q8n as well. Accordingly, circuit parts connected to the terminals 31,32 to 3m respectively can be made active. On the contrary, in the case the voltage impressed to the control circuit 5 is 5V, an output current I5 flows, and if a condition I2<I5 is set beforehand, no current flows in the TR Q7, and therefore, the currents I41, I42 to I4m do not flow as well, and the circuit parts connected to the terminals 31 to 3m are made inactive, and since the amplifier can be turned ON/OFF without using the element of the large power consumption such as a relay, etc., a device can be made of a low consumption type.

The x polarized light of y polarized light is introduced from one end of the waveguide as the fundamental wave to generate a secondary higher harmonic stably without any adjustment with the polarized light orthogonal to the fundamental wave. As a result, a waveguide-type wavelength conversion element without wave front aberration in the SHG output light and high in tolerance for design, fabrication and ambient temp. change is obtained.

Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To keep good uniformity at the surface of etching to easily obtain the desired etching shape through the processing of a conductive film including tungsten by alternately repeating the plasma etching process using a gain mainly composed of fluorine and the oxygen radical process. SOLUTION: At the time of processing a tungsten film 4, the plasma etching process for tungsten film 4 using a gas mainly composed of fluorine and the oxygen radical process for processing the surface of tungsten film 4 with oxygen radical are alternately repeated. Therefore, since the gas which is mainly composed of fluorine is used, ununiformity in the surface of the etching is never generated. Although a tungsten oxide film 7 is formed at the surface of tungsten film 4 in the oxygen radical process, this tungsten oxide film 7 functions as an etching protection film. Therefore, the tungsten film 4 at the surface where a large amount of gas is supplied is etched in he next etching process but the tungsten film 4 at the other surface is protected by the tungsten oxide film 7 and is never etched.
