Title: Method and element for discriminating optical fiber mode
Inventor: SASAKI KAZUMASA
IPC: G02B6/293
Filed: 1987-06-13
Abstract: PURPOSE:To easily discriminate the propagation mode of light being propagated in an optical fiber, by forming an optical smooth plane by cutting the tip of the optical fiber at a specific angle, and using the Snell's law and a total reflection phenomenon. CONSTITUTION:The specific mode of the light being propagated in the optical fiber can be discriminated or deleted by forming the optical smooth plane 3 by cutting the tip of the optical fiber at the specific angle (alpha), and utilizing the Snell's law and the total reflection phenomenon with respect to the refraction of the light on the plane 3. In other words, it is possible to discriminate the mode by transmitting a beam of light of sin(alpha)<1/n and reflecting the beam of light of sin(alpha)>1/n for the beam of light having an inclination angle (alpha), thereby, an element can be formed as a micro optical circuit element. In such a way, it is possible to discriminate the mode of the light being propagated in the optical fiber 1 by a very small element, and to improve the characteristic of an optical fiber line.

Title: Reference voltage generating circuit
Inventor: IRIE KOICHI
IPC: H03M1/10
Filed: 1992-06-08
Abstract: PURPOSE:To generate the optimum reference voltage with no adjustment by measuring the fluctuation of the designed value of an analog IC element parameter with use of an A/D converter. CONSTITUTION:An analog IC element parameter measuring means 54 measures the value of an analog IC element parameter. A reference voltage generating means 53 sets the circuit constant of a reference voltage source 10 based on the output signal of the means 54 so that the temperature drift of the output voltage is minimized. The means 53 also defines the output of the source 10 as the reference voltage output. The input voltage of a comparing means 9 varies according to the variance of the designed current amplification factor of a transistor 5. Thus the current amplification factor can be measured with conversion of the input voltage of the means 9 carried out by an A/D converter 52. In such a way, the fluctuation of the designed value of the analog IC element parameter is measured by the converter 52 and the optimum source 10 can be selected by a multiplexer 8 with no adjustment and in response to the fluctuation of the parameter.

Title: Electronic component positioning equipment
Inventor: OKADA TAKESHI
IPC: H05K13/04
Filed: 1988-06-15
Abstract: PURPOSE:To make adjustments of component usually with the minimum opening and closing movement of clicks and the minimum shock by including a driving source to vary the ring length in a positioning claw opening and closing movement driving mechanism and by closing in advance the positioning claws until they close enough to keep only the minimum necessary clearance with the component according to the size of the component. CONSTITUTION:Between levers 4 and 8, a servo driving mechanism is incorporated to vary the distance between these levers. By this mechanism, a head rotates and an electronic component is moved right over positioning clicks. Coincidently with this, the positioning claws start closing according to the size of the component. After the head stops intermittent rotation, a nozzle goes down to carry the electronic component to the center of the positioning claws 11. By this time, the positioning claw 11 have already closed enough so as to keep the minimum necessary clearance with the component. Therefore, only a fixed stroke is required to position the component. By this equipment, it is possible to readjust the component usually with the minimum movement of the claws and the minimum shock even when the size of the component changes.

IPC: H04J3/06
Filed: 1984-07-19
Abstract: PURPOSE:To attain synchronizing data transmission in a multi-direction microwave line by unifying a synchronizing clock and constituting a synchronizing subordinating transmission system. CONSTITUTION:Transmission data from a terminal device 9 is subjected to speed conversion at a data terminal station 1 by using a CLK1 from an external subordinate clock generator 21, transmitted to a PCM terminal station 2, where the data is multiplexed by the CLK1 from the external subordinate clock generator 21 and the result is transmitted to a demodulation section 4 of a radio equipment section. The demodulation section uses a CLK2 and after a data of 1.5Mb/s is demodulated on a channel at each terminal device, the result is transmitted to a transmission section of a radio equipment 7 and transmitted from an antenna ANT by each slave station from the transmission section. An external subordinate clock generator 22 generates the 1st clock CLK1 in complete synchronization with the 1st clock used at a carrier end of a master station by using the transmitted 2nd clock CLK2. Thus, the data transmitted from the PCM terminal station 12 to the data terminal station 13 is reproduced in a complete form and the synchronizing data transmission is attained.
