Title: Interconnection method of optical switch
Inventor: POORU ANSONII KAAKUBII
IPC: H04B10/27
Filed: 1995-05-24
Abstract: PURPOSE: To provide a method for mutually connecting light switches by which the problem of a crosstalk by nonlinear operation resulted from power level fluctuation of a transmission path including a wavelength multiplexed signal is solved. CONSTITUTION: An ATM switch has a N×N light crossing connecting core 1, and ATM switch cores containing N-pieces of port card 21 sets, each of which comprises a selector 22. It is a satellite 3 that each port card 2 is related to. A wavelength multiplexed wavelength shift key signal is used to route an ATM cell through the ATM switch core between the satellites 3 by use of an optical fiber. In this method for mutually connecting light switches, the data is transmitted from one locating to the other location through at least one optical space switch in the form of a wavelength shift-keyed wavelength multiplexed light signal.

Title: Synthesizer and distributer
Inventor: KURACHI KOICHI
IPC: H01P1/165
Filed: 1986-06-27
Abstract: PURPOSE:To contrive to attain broad band synthesis/distribution, low loss and quick adjustment by combining two orthogonal polarized branching filters and two circularly polarized wave generators. CONSTITUTION:The circularly polarized wave generators 2, 3 are formed by inserting irises 22, 32 in circular waveguides 21, 31 as fine phase elements and the broad band characteristic is attained by selecting the irises 22, 32. In giving signals whose phases and levels are made coincident and whose direction of electric field is orthogonal to each other to terminals 11, 12 of an orthogonal plalizing branching filter 1, the signal is converted into a circularly polarized wave, which is inputted to a circularly polarized generator 3, where the wave is converted into a vertically polarized wave and the orthogonal polarized wave branching filter 4 outputs the vertical polarized wave to a terminal 41. In branching the signal inputted from the terminal 11 into terminals 41, 42, the turning angle of a circular waveguide 21 is adjusted so that the linearly polarized wave inputted from the orthogonal polarizing branching filter 1 is outputted as it is.

Title: Polarization control method
Inventor: SHIMIZU HARUHITO
IPC: G02F2/00
Filed: 1988-06-17
Abstract: PURPOSE:To convert polarized light which varies optionally and continuously into horizontal or vertical polarized light continuously without any break by using three optical phase modulators. CONSTITUTION:The polarization controller consisting of 1st-3rd optical phase modulators 100a-100c converts the optional polarized light which is incident from the 3rd optical phase modulator 100c into elliptic polarized light with a 45 deg. angle of polarization and then the 1st optical phase modulator 100a converts this circular polarized light into the horizontal or vertical linear polarized light. Normally, phase differences PHI1 and PHI2 that the 2nd and 3rd optical phase modulators 100b and 100c give to the propagated light are adjusted respectively to perform polarization control. Here, when the phase differences PHI1 and PHI2 reach the operation limit, the 1st optical phase modulator 100a is operated to reset the phase differences PHI1 and PHI2 while performing the polarization control and normal operation is started. Consequently, the polarized light which varies optionally and continuously is converted into the linear polarized light continuously without any break.

Title: Oil-impregnated sintered bearing and manufacture thereof
Inventor: MATSUMOTO KENZO
IPC: F16C33/14
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To provide an oil-impregnated sintered bearing to extremely reduce rotational friction resistance and decrease consumption of lubrication oil and to manufacture thereof. SOLUTION: A bearing 1 is inserted in a die 5 and compressed by an upper punch 7 and the inner peripheral part of the hole part 1a of the bearing 1 is forced into adhesion to the protrusion 4a and the groove 4b of a mandrel 4. When a lower punch 6 is then raised with the mandrel 4 left standing, the bearing 1 is extruded from the die 5 as the protrusions 2... are slightly squeezed by the protrusion 4a of the mandrel 4. In this case, the protrusions 2... and the grooves 3... are left on the inner peripheral of the hole part 1a through spring back of the bearing 1. Since porosity of the vicinity of the ridge parts of the protrusions 2... is decreased to a value lower than that of other part, an oil film is always formed on a slide surface with the shaft and besides surplus lubrication in the groove 3 is apt to be absorbed in the interior, whereby outflow of lubrication oil is low.
