Patent JP-H0287102-A (JP)
Title: Optical circuit board
Inventor: TAKAGI KOJI
IPC: G02B6/12
Filed: 1988-09-24
Abstract: PURPOSE:To reduce crosstalk by incorporating a light absorbing agent which absorbs light with a wavelength propagated in a core and a light scattering cutoff agent in the clad of the core. CONSTITUTION:The optical circuit board 1 has the core 11 where the light is propagated, the clad 12 of the core 11, and a substrate (base material) 14 which holds them and is in three-layered structure. In such a case, the clad 12 arranged outside the core 11 contains the light absorbing agent which absorbs the light with wavelength propagated in the core and the light scattering cutoff agent, and consequently light leaking from the core 11 is hardly transmitted through the clad 12. Consequently, light B2 existing from the core 11 of, for example, an optical waveguide is reduced greatly by absorption, scattering, shielding, etc., to prevent the crosstalk.

Abstract: PURPOSE:To reduce a gate power source capacity by disposing a circuit for regenerating power to the power source from a main circuit power source separately from a snubber circuit. CONSTITUTION:A voltage applied to a load circuit 2 is controlled in a main circuit configuration of a chopper circuit by altering the ratio of the firing period to an extinguishing period of a self-extinguishing thyristor 3.

Title: Surface emission semiconductor laser
Inventor: KOMAZAKI IWAO
IPC: H01S5/00
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To obtain a linearly polarized light stably by a structure wherein the cross-section of light emitting region, in parallel with the major surface of semiconductor substrate, has long and short axes, a reflective layer is provided on the side face of light emitting region, an upper electrode is provided on an upper distributed reflector layer, and a lower electrode is formed on a lower distributed reflector layer on the outside of reflective layer while sandwiching a resonator. SOLUTION: A current injected from a p-type electrode 8 passes through an upper distributed reflector layer 6 and flows into a lower distributed reflector layer 2 after emitting light in a resonator. Since one n-type electrodes 11a, 11b are paired with respect to the short or long axis of resonator, the current flows through the resonator while being shifted toward the electrode. Consequently, carriers migrate in the resonator while being shifted toward the electrode a linearly polarized light, where the distribution of light is shifted correspondingly, can be produced. The vertical resonator comprises an upper clad layer 5, a lower clad layer 4, and an active layer 3 sandwiched between and surrounded by the upper and lower distributed reflector layers 6, 2.

CONSTITUTION:A dog-bone billet 64 with a dog-born section shape, is attained by arranging plural box calibers with flat caliber bottoms and with different bottom widths on a coarse rolling mill, drawing down a slab 5 in the width direction by each caliber, and rolling while gradually widening a flange width like materials 61, 62 and 63 to be rolled while supporting the material to be rolled. successively, the dog-born bullet 64 is allowed to rotate by 90 deg., and a web is directly and strongly drawn down by upper and lower horizontal rolls in the path of the preceding stage of a coarse universal rolling mill 2a. In this case, a distance (d) from the surface of the short side of the slab of a center segregation band tip part 12 in the slab 5, is made, for instance, to be 1/2 of a slab width t0. Consequently, it is possible that the center segregation band does not appear near the surface on the outer side of the flange of a product.

Title: Preamplifier for receiving remote control signal
Inventor: ADACHI YASUSHI
IPC: H04L27/06
Filed: 1984-11-13
Abstract: PURPOSE:To obtain high signal selectivity with no adjustment by using a synchronous detector of phase locked loop type as a filter extracting a signal component from an output of an automatic gain control amplifier. CONSTITUTION:A signal in a frequency fs is compared with an oscillation frequency fVCO of a voltage controlled oscillation circuit 24 by a phase comparator circuit 21. When the relation of fs>fVCO=fo exists, an error output of the comparator circuit 21 is increased positively to increase positively a control voltage Vc of the oscillation circuit 24 via a low-pass filter circuit 22 and a DC amplifier circuit 23, then the oscillation frequency fVCO is increased and approaches the fs. The operation above is repeated and when the fVCO reaches the fs, the locking state is obtained. Before a signalis given, a synchronous detection output 27 is Vo(<Vref), a high level during this time, but as soon as the voltage of the inverted input to a comparator 25 exceeds the reference voltage Vref(<Vs), the output 27 goes to a low level. When no signal exists at an input terminal 2, the oscillation circuit 24 is in the free running state and the level of the output terminal 3 goes to a high level as soon as the detection output 27 is lower than the reference voltage Vref while the output 27 goes from the Vs down to the Vo.

Title: Ceramics heat generator
Inventor: TASHIRO HIROSHI
IPC: C04B35/58
Filed: 1988-09-26
Abstract: PURPOSE:To secure a conductibility, to improve the relative density so as to secure the use in an oxidizing ambiance, and to secure a mechanical strength, by mixing a specific wt. pt. of titanium boride powder and aluminum oxide powder to a specific silicon carbide, and sintering it in an inert gas ambiance at a specific temperature. CONSTITUTION:To 25 to 75 wt.pt. of silicon carbide SiC powder, 20 to 70 wt.pt. of titanium boride TiB2 powder is mixed, and 3 to 26 wt.pt. of aluminum oxide Al2O3 powder is also mixed. After that, the mixture is sintered in an inert gas ambiance at the temperature 1700 deg. to 2000 deg.C. The reason that the mixing ratio of the titanium boride TiB powder is made 20 to 70 wt.pt. is that the conductibility of the product to be a ceramics heat generator is reduced when the mixing ratio is less than 20 wt.pt. And when the mixing ratio exceeds 70 wt.pt., the sintering property is deteriorated, and the mechanical strength is reduced.

Filed: 1988-09-28
Abstract: PURPOSE:To prevent any breakthrough from occurring thereby facilitating the flattening process by a method wherein the surface layer of polysilicon is made amorphous by ion-implantation of Si while a gate electrode is processed by photolithography and anisotropical etching process and then source/drain are formed using the amorphous gate electrode as a mask. CONSTITUTION:A relatively thin polysilicon 106 is deposited, e.g., in thickness of 1500Angstrom  to turn polysilicon into N<+> in POCL3 atmosphere at 900 deg.C. Next, Si is ion-implanted, e.g., at 20Kev, 2.5E 12cm making the surface layer amorphous to form an amorphous layer 107. Later, a gate electrode 106 having the amorphous layer 107 is processed by normal photolithography and anisotropical etching process. Then, an insulating film 108, e.g., CVD-SiO2 is deposited in depth of 3000Angstrom  to form a sidewall 108 on the side of the gate electrode 106 using the anisotropical etching process. Finally, a P<+> diffused layer 109 is formed using the sidewall 108 and the amorphous surface layered gate electrode 108 as masks. Through these procedures, a sidewall structured PMOSFET can be formed.

Filed: 1988-09-28
Abstract: PURPOSE:To improve the accuracy in detection by a construction wherein the outside of a thin-wall part in each of beam parts in the directions X and Y is fixed on the central part of each of support beams intersecting the beam parts perpendicularly. CONSTITUTION:In a distributed-type pressure sensor 300, deep groove parts 31A and 32A are formed with additional ones provided on the opposite sides respectively, in the longitudinal and lateral directions. Moreover, four rectangular through holes 33A are provided afresh along the deep groove parts 31A and 32A. The opposite end parts of beams 140 and 141 in the directions X and Y are supported by fixed support beams 48. When the sensor 300 thus constructed is fixed on a lower substrate, both of the beams 140 and 141 are fixed on and supported by the respective central parts of the support beams 48, which support said beams in the condition that the opposite sides of a projecting part 35 as the center are kept symmetric. Accordingly, the mutual interference between component forces, which is caused by the condition of a non- symmetric support of the beams, can be excluded, and thus a load applied on the projecting part 35 can be reduced to component forces in the directions X, Y and Z exactly by semiconductor strain gages 42 and detected.
