Title: Maximum likelihood demodulating method and receiver
Inventor: IZUMI SEIICHI
IPC: H04B1/10
Filed: 1995-03-16
Abstract: PURPOSE: To prevent power from being wasted by segmenting a block, in which a specified mutual correlation function is made maximum with the small number of bits, when the specified mutual correlation function is concentrated in the block composed of bits less than the prescribed number of bits corresponding to maximum propagation delay with the rate larger than a prescribed value. CONSTITUTION: At an arithmetic circuit 23, the mutual correlation function of received data on one memory 21 and a synchronized bit pattern in another memory 22 is calculated and viterbi processing is performed while using this mutual correlation function. Then, a transmission line is estimated by segmenting the block in which the power of the mutual correlation function is most concentrated. Namely, the channel of transmission line is estimated by segmenting the block in which the square power of the absolute value of mutual correlation function is made maximum. Thus, when the delay of transmission line is small, that mutual correlation function is concentrated in the block composed of bits of a smaller number than a prescribed one at the rate larger than the prescribed value. Therefore, the block in which that mutual correlation function is made maximum can be segmented with the small number of bits.

SOLUTION: A pressure sensitive adhesive layer 3 is formed on the mounting surface 21 of a member body 2, and a net type sheet is attached to the surface of the layer 3. Then, an interior member is pressed to surface as a mounting position. In this case, the net type sheet is formed to be buried in the pressure sensitive adhesive layer 3, when the interior member 1 is pressed to the surface 51. Furthermore, the member body 2 is made as a plate type by expanding polyvinyl chloride to an approximately double volume and orthogonally bending the expanded polyvinyl chloride. The mold releasing paper of the interior member 1 is first removed and, then, the interior member 1 is attached to the projected corner of an interior wall 5 having a plaster board attached, as a baseboard corner material.  In this case, the interior member 1 is kept in light contact with the corner of the interior wall 5, and bonded thereto under a strong pressing force after positioned. Thereafter, long-sized baseboards 10 and 10 are provided at both sides of the interior member 1 in accordance with a similar procedure for erecting the interior member 1.

Title: Automatic gain control device
Inventor: FUJIMURA NORIAKI
IPC: H03G3/30
Filed: 1979-07-06
Abstract: PURPOSE:To secure the steady and high-speed draw-in of the automatic gain control device, by holding the control voltage of the voltage control amplifier at a certain level even in case no input signal exists. CONSTITUTION:Oscillator 6 and adder 7 are provided. Oscillator 6 generates the signal lower than the prescribed level, such as the initialized signal, and then operates in response to the detection signal of carrier detector 5. In other words, the initialized signal is sent to adder 7 in case when the voltage of the detection signal is at a low level. On the contrary, oscillator 6 sends no initialized signal when the detection signal is at a high level. Accordingly, the input signal of voltage control amplifier 1 does not become to the zero level, and thus the control voltage can rise rapidly up to the stabilized voltage. Thus the control voltage rises up at the level higher than the zero level. As a result, the steady and high-speed draw-in is possible for the automatic gain control device.

Abstract: PURPOSE:To obviate a lock plate, a tension energizing means, a fixture for fixing the lock plate, and the like so as to reduce the number of parts by engaging a tensioner jig with an engaging hole provided in conformity with the center of an eccentric hole to provide initial tension. CONSTITUTION:A tensioner jig 40 is engaged with an engaging hole 38 provided in conformity with the center of an eccentric hole 30 to provide initial tension. A lock plate, a tension energizing means, a fixture for fixing the lock plate, and the like thereby become unnecessary. A fixed member (shaft) 20 is rotated around the center of the eccentric hole 30 as the rotational center by the tensioner jig 40 without thus using the tension energizing means to provide the specified initial tension and then fixed by a fixture 36 inserted into a circular fixture through hole 32 having the center of the eccentric hole 30 as its rotational center, and this enables the prevention of prankish initial tension fluctuation caused by the energizing force dispersion of the tensioner jig 40.

CONSTITUTION: After formation of a lower-layer aluminum wiring 2a and a via hole 6 is executed and a tungsten film 7 is formed thereon, an upper-layer aluminum film 8 is formed. Next, a resist pattern 9 is formed and the upper- layer aluminum film 8 is etched selectively in relation to the tungsten film 7 with this pattern used as a mask. By etching the tungsten film 7 selectively in relation to the lower-layer aluminum wiring 2a and by removing the resist film 9, subsequently, an upper-layer wiring 8a is formed in a borderless manner in relation to the via hole 6. Even when the upper-layer Al wiring slips out of place in relation to the via hole, according to this constitution, multilayer interconnection can be formed without damaging the lower-layer Al wiring.

Title: Melt-sticking connection method of single mode optical fiber
Inventor: KATOU YASUYUKI
IPC: G02B6/255
Filed: 1980-06-24
Abstract: PURPOSE:To obtain a melt-sticking connection method whose connection loss is low by connecting cores by melt-sticking after uniting the axial centers of cores and operating the holders of optical fibers while heating the melt-stuck part so that the cores are arranged straightly. CONSTITUTION:Single mode optical fibers A1 and A2 to be connected are set on holders 1 and 2 and these connecting ends 3 and 4 are opposed by separating them only by a slight space. While monitoring the light transmitted through the fibers with a light source 5 such as a semiconductor laser and a light detector 6, the axial centers of cores B1 and B2 are united by controlling the positions of connecting ends 3 and 4. The connecting ends 3 and 4 are arc welded with a pair of electrodes 7 and 8. In order to compensate the curve of cores B1 and B2 in melt-stuck part C, arc is generated again on the melt-sticking part with the pair of electrodes 7 and 8 to heat the welding part and the optical fiber A1 or A2 are moved slightly to the horizontal or vertical direction. Since the curve of cores can be compensated by the above-mentioned procedure, melt-sticking connection with low connection loss is made available.
