IPC: F04C18/107
Filed: 1992-05-29
Abstract: PURPOSE:To improve wear resistance even when a lubricating oil film is broken by a method wherein a slide part on the rotary body side is formed of an Fe metal on which a specified quenched cured layer is formed and a slide part on an Oldham's ring side has hardness of HV400 or more.

Title: Automatic equalization system
Inventor: TAMORI MICHITOSHI
IPC: H04L25/03
Filed: 1980-10-07
Abstract: PURPOSE:To shorten the time for setting the tap weight of an equalizer by performing high-speed Fourier transformation by calculating the mutual correlation  value of a complete orthogonal signal for training sent from a transmisiion side and  a complete orthogonal signal generated at a reception side. CONSTITUTION:A complete orthogonal signal for training sent from a terminal 1 has intercode interference on a transmission the line 2 and enters a correlator 3 through the terminal a1 of a switch (SW)1. The correlator 3 calculates the mutural correlation value of the input signal and a complete orthogonal signal of a reception side from a terminal R and after high-speed Fourier transformation FFT4, reciprocal arithmetic 5 and high-speed reverse Fourier transformation 6 are performed successiely, the resulting signal is inputted to a convolutional integrator 7, which sets the tap weight of an equalizer 8. Then, the SW1 is changed over to a terminal b1 to set the signal mode of random data, and a distorted waveform is corrected by the equalizer 8 to input the corrected signal to a divider 10 through a discriminator 9, the terminal d2 of an SW4, FFT4, and the terminal d1 of an SW3. The divider 10 divides this input signal by the output signal of a transformer 4 which inputs a signal through the discriminator 9, thereby re-setting the weight of the equalizer.

Abstract: PURPOSE:To avoid the application of the excessive input voltage to the analog switch by reducing the input-output terminal voltage of the analog switch under the allowance voltage via the Zener diode and then feeding to each OP amplifier and the analog switch from the common power source. CONSTITUTION:OP amplifier 12 operates on plus and minus power sources +VA and -VB.

Title: Fixing structure for optical fiber
Inventor: OOMORI YASUICHI
IPC: G02B6/00
Filed: 1992-06-02
Abstract: PURPOSE:To enable the transmission of a relatively high-energy laser with a silver halide fiber without buckling and deforming of the fiber by fixing the fiber with the specific fixing structure. CONSTITUTION:A fixing member 1 made of phosphor bronze is formed with a through-hole 2 in its axial central direction and a gold plating film 3 is deposited on the inside surface of this through-hole 2. The AgCl/Br fiber 4 is fixed by an epoxy adhesive 6 into which metal, such as gold powder 5, or ceramics or carbon is incorporated. The fiber 4 is coated with an internal tube 7 made of 'Teflo(R)' for reinforcing the mechanical strength thereof. Scattering increases and heat is generated near an incident end 9 when a CO2 laser 10 is made incident from the incident end face 9. The gold powder 5 is incorporated into the epoxy adhesive 6 in proximity to the fiber 4 and, therefore, the thermal conductivity is good and the heat is transferred through the gold plating film 3 to the fixing member made of the phosphor bronze, by which the heat is radiated. Then, the cooling property is good and the temp. rise at the terminal part is low even if the high-output laser is made incident. There is no need for press fitting the fiber to fix the fiber and the deformation, such as buckling, of the fiber does not arise.
