Title: Polarization demultiplexing optical element
Inventor: ITOU MASATAKA
IPC: G02B27/28
Filed: 1982-09-13
Abstract: PURPOSE:To realize small-sized constitution and low loss by providing closely the 1st optical waveguide which has a greater refractive index than a crystal substrate and the 2nd optical waveguide which has a refractive index which is a specific value greater and an equal propagation phase constant. CONSTITUTION:An optical waveguide 2 is formed of a high-refractive-index layer by the thermal diffusion of metal on the crystal substrate 1. This optical waveguide 2 increases in refractive index by about 0.01 at a maximum to enable the propagation of both a TE and a TM wave. Further, an optical waveguide 3 where only the TM wave propagates is provided closely to the waveguide 2 to form a photocoupler. At this time, only the refractive index to extraordinary light increases by about 0.12 at a maximum. Therefore, only the TM wave propagates in the waveguide 3 and the TE wave does not propagate. Further, the TM waves propagating in the waveguides 2 and 3 are equalized in propagation phase constant. Consequently, the TE and TM waves are demultiplexed completely to the waveguides 2 and 3 respectively to obtain projection light 5 and projection light 6. Thus, the polarization demultiplexing optical element of small-sized constitution with low loss is obtained.

Title: Automatic gain controlling circuit
Inventor: YOKOGAWA TAKASHI
IPC: H04B3/10
Filed: 1980-11-13
Abstract: PURPOSE:To prevent an overload on a trailing amplifier by performing switching to a fixed gain circuit for a constant time in case of the sudden level rise of an input pilot signal, and by exercising automatic gain control after the resistance of a thermistor is stabilized nearly having a value at the time of a standard pilot level. CONSTITUTION:A transmitted signal and a pilot signal are passed through a gain controlling circuit consisting of an amplifying circuit AMP1, resistors R2 and R3, and the resistance of a thermistor TH; and then the pilot signal is extracted through a band-pass filter BPF to amplify its variations by an expanding circuit EXP, and consequently a thermistor current is obtained to control the gain of the gain controlling circuit, holding its output constant. Further, a level comparing circuit COMP detects the level rise of the pilot signal, and a time limit circuit TIM is put in operation by the detection output to connect the contact rl of a relay RL to a fixed resistance RI. Consequently, since a fixed gain circuit is made effective by switching, the output level rise is stopped and after the resistance of the thermistor TH is stabilized, the contact rl is returned to make the normal automatic gain controlling circuit effective.

Title: Method and device for ageing green body
Inventor: NAKAMU EIJI
IPC: C04B35/64
Filed: 1992-06-18
Abstract: PURPOSE:To prevent a compact from being deformed or adsorbing moisture, etc., by transiently transforming a green body into an intermediate tentatively called 'a yellow body' in the physically stabilized region. CONSTITUTION:A green body obtained by compacting a mixture of powder and binder is kept at a temp. where a part of the low-mol.wt. component bL in the binder B is melted at atmospheric pressure and the green body is not softened or gradually heated and heat-treated, and an yellow body W(Y), in which the high-mol.wt. component bH is locallized in the green body, is obtained. The component bH is reticularly bundled in the yellow body, and the shape of the compact is held over a wide range by the bundles. Accordingly, even if the component bL is then melted and vaporized when the compact is degreased, sagging is effectively prevented. Meanwhile, since the yellow body is degreased only by several wt.% and the powder surface is covered with the binder, the oxidation of powder and adsorption of moisture is effectively obviated.
