Title: Method for driving electro-optical device
Inventor: MAEDA TAKESHI
IPC: G02F1/133
Filed: 1991-04-12
Abstract: PURPOSE:To stably drive an electro-optical device with a large area, high accuracy and a low cost in a high contrast and high picture quality state. CONSTITUTION:When the post stage line selective potential VSB of the n-th row scanning electrode and the prestage line selective potential of the (n+1)th scanning electrode are simultaneously impressed to respective scanning electrodes, the non-linear resistance elements of plural picture element groups held between both the scanning electrodes are set up to low resistance values, these picture element groups are selected and data are written from the m-th column counter electrode. Since the potential levels of both scanning electrodes are held to VNS in a holding period, the non-linear resistance elements are turned to high resistance values and the written charge is held. Thereby the number of scanning electrode lines can be reduced to a half of convensitional structure.

Abstract: PURPOSE:To execute welding of triplex base metals with one process and to maintain adequately the quality and strength of a weld zone by pressing the welding projections of reinforcing and auxiliary base metals which are thick and are different in thickness to the respective surfaces of a thin basic base metal and conducting specifically electricity thereto. CONSTITUTION:The respective welding projections 6, 4 of the auxiliary base metal 5 and the reinforcing base metal 3 are disposed to the top and bottom surfaces of the basic base metal 1 in contact therewith in the case of subjecting, for example, the inlet pipe coupling part of a fuel tank for a vehicle to projection welding. Electrodes for projection welding are thereupon disposed above and below the contact parts of the base metals 1, 3, 5 and the pressurizing force of a specified value is exerted continuously thereto. Electricity is first conducted between the thinner projections of the base metals 3, 5 and the base metal 1 at and for a required current value and time and thereafter the conduction of electricity is paused for the time required for cooling the melt-bonded part. The electricity is similarly conducted between the melt-bonded part and the projections of the thicker base metals, by which the base metals are welded.

Title: Parametric diode amplifier
Inventor: DEEBITSUTO KEE DONARUDO
IPC: H03D7/02
Filed: 1986-04-08
Abstract: PURPOSE:To perform heterodyne detection/amplification on lights to be modulated at a high efficiency over a wide modulation frequency range, by biasing a photodiode against a voltage, whose I:V curves intersect each other, in the upper and lower sides with a local oscillator (LO) and exposing the photodiode to the lights to be modulated having very high intensities. CONSTITUTION:The 1st lead of a photodiode 11 is connected with the earth 12 and the photodiode 11 is exposed to lights 13 which are modulated by an RF frequency and having a high intensity. The 2nd lead is earthed through a high-pass filter of 8GHz. The 2nd lead is also connected in series with a local oscillator 17 through a low-pass filter of 6GHz and high-pass filter 16 of 2GHz and produces a bias to be applied to the photodiode 11, and then, generates an output signal of intermediate frequency (IF) to an output 19 through the low-pass filter 15 and another low-pass filter 18 of 1.5GHz. When no light is made incident, an I:V curve 41 is obtained. The I:V curve becomes curves 42 and 43 as the intensity of the light level increases. The curve 43 has the same shape as the curve 41 has, but shifts to both directions of I-axis and V-axis and, as a result, a strong heterodyne effect is produced.

Title: Information transmitting system using answer frame for loop type bus using token passing system
Inventor: INABA ATSUNORI
Filed: 1988-04-01
Abstract: PURPOSE:To improve information transmitting efficiency by discriminating whether an answer frame containing the transmission information is addressed to its own node or not when the frame passes through and receiving the corresponding part. CONSTITUTION:A node A receives an answer frame containing the transmission information and identifies whether an answering destination pattern 31 of an answer part 300 and a self-addressed frame identification pattern A2 are equal to a self-addresses answer part or not via a comparator A3. If so, the part 300 is received by a data receiving circuit A4 as the confirmation for reception of the transmission information sent from a node B. Then the circuit A3 identifies whether a transmitting destination pattern 34 of a transmission information part 310 and the pattern A2 are equal to own address transmission information part or not. If so, the part 310 is received by the circuit A4. Thus the transmission of information is possible not only with a token frame but an answer frame.
