Title: Communication system and modem
Inventor: BREMER GORDON
IPC: H04J7/00
Filed: 1994-06-13
Abstract: PURPOSE: To simultaneously transmit analog information and digital information by arranging an analog signal constellation near a sampling point of digital signals in a orthogonally transformed signal space. CONSTITUTION: A mapper 60 divides a digital stream on a line 61 into words and forms each word in a pair of symbol components 62 and 63 composed of pulses having a prescribed amplitude. Another mapper 50 samples analog signals on a line 51 and forms each pair of continuous samples in a set of vector components 52 and 53 composed of pulses having continuous amplitudes. The amplitudes are limited to <=1/2 of the distance between symbol components. Adders 70 and 80 respectively add in-phase orthogonal components of the vector components 52 and 53 and symbol components 62 and 63 to each other and sends the sums to quadrature modulators 120 and 130 through LPFs 150 and 160. A receiver first demodulates the digital signals and, after subtracting the modulated digital signals from the received signals, demodulates the analog signals.

Filed: 1979-11-29
Abstract: PURPOSE: To mold a large-size mold by the use of a molding device for a samll- size mold at high speeds by fluidizing the mold material and blowing this fluidized material wet to the pattern surface.  
     CONSTITUTION: Refractory powder is added to ordinary sand of refractory particles, a binder and a hardener, and these are made into a slurry by means of a water and  a dehydrating agent. This slurry is required to have the fluidity required as a molding material and the characteristic that the materials do not separate. This slurrylike molding material is blown or projected to the pattern surface by compressed air  or a spinner. At this time, ordinary mold release agent is beforehand coated on the pattern surface. Next, backing sand 4 is molded onto this slurry blown layer or projected layer and the mold is rapped, whereby the mold is produced. since the dehydrating agent and refractory powder are added, the viscosity of the slurry increases and this enables material separation to be prevented and shear droop to be prevented. In addition, the molding efficiency is improved on account of blowing molding.

Abstract: PURPOSE:To stabilize the delay time and the temperature characteristics of a characteristic impedance, by setting a thermal expansion coefficient of a substrate, where plural coils are fixed in parallel, so that this coefficient and the variation due to the temperature variance of the inductance of coils are cancelled by each other. CONSTITUTION:Plural coils 1 where wires 8 are wound around drum cores 7 are arranged and fixed to a substrate 9 at prescribed intervals with parallel axial directions. An overall self-inductance L0 of coils 1 is equal to a value obtained by adding a mutual inductance M between coils to an intrinsic self-inductance L. A thermal expansion coefficient of the substrate 9 is set to such value that variation DELTAL0 of the self-inductance accompanied with the variance of the temperature of coils 1 is  cancelled practically by a mutual inductance DELTAM due to the variance of the temperature. Series of coils formed in this manner are connected in series, and capacitors 2 are connected in parallel, thereby stabilizing the delay time and the temperature characteristics of a characteristic impedance even if a core of a high temperature coefficient of the inductance is used.

Filed: 1983-08-23
Abstract: PURPOSE:To prevent the malfunction of an AGC detecting circuit or the like by setting a level higher than the level, which falls a burst gate pusle, during an input synchronizing signal to cut off a means which rises the pulse. CONSTITUTION:An input terminal IN is connected to the base of a transistor (TR)Q1 through a resistance R13 and is connected to the base of a TRQ16. The collector of the TR Q16 is connected to a power source VCC, and the emitter is connected to emitters of TRs Q9 and Q10. A base potential VX of the TRQ16 at the time, when the synchronizing signal supplied to the input terminal IN is in the high level, is so set that V2<VX is true when the potential of a constant voltage source is denoted as V2. Consequently, when the input synchronizing signal is in the high level, the TR Q10 is cut off, and the burst gate pulse is not generated. That is, the burst gate pulse is not outputted during the vertical synchronizing signal.

IPC: G02F1/1335
Filed: 1992-06-12
Abstract: PURPOSE:To make a color reproducing range wide by preventing color mixture from occurring and to improve yield by providing an exchangeable color filter. CONSTITUTION:The thickness D2 of a substrate 5b near the microlens array 4 of a liquid crystal display panel 5 is made thicker than the thickness D1 of a substrate 5a being distant from the array 4. As the result, even when there is aberration on a microlens 4a and a focal distance is shorter than the thickness D2 of the substrate 5b near the array 4, the light conventionally causing the color mixture is shielded by the light shielding part of the panel 5 because the substrate 5a being distant from the array 4 is formed thin. That means, the light passed through a picture element electrode 10 is surely made incident on the corresponding color filter 6a.
