Filed: 1982-10-22
Abstract: PURPOSE:To prepare the titled compound in high yield and purity, by reacting acrylic acid or methacrylic acid with a dialkylaminoalkylamine at a specific ratio in the presence of a specific separation agent while removing the produced water from the system, and thermally decomposing the reaction product. CONSTITUTION:1mol of acrylic acid or metacrylic acid is made to react with 1.5-1.8mol of the compound of formula I (R<1> and R<2> are methyl or ethyl; n is 2 or 3) in the presence of a separation agent (e.g. benzene) to suppress the azeotropic distillation of the compound of formula I and produced water, and at the same time, to remove the produced water from the system by the selective azeotropic distillation of produced water with the separation agent. The amidation reaction takes place by this process to obtain the amide of formula II as an intermediate. The objective compound of formula III can be prepared by the thermal decomposition (usually at 150-300 deg.C) of the intermediate. The formation of by-products caused by the polymerization of vinyl groups in the preparation of the intermediate can be suppressed by this method, and the loss of the raw material by the distilling out of the system can be inhibited, and accordingly, the objective compound can be prepared in extremely high efficiency.

Filed: 1984-09-07
Abstract: PURPOSE:To decrease the number of buffers for unnecessary operation and to reduce power consumption by providing a switching for turning off all non- selection gates and bringing a non-selection CMOS buffer input to '1' or '0' fixed value. CONSTITUTION:A switching means Q [Pch transistor (TR)] to fix the level of an input of buffers A0-A3 to '1' is added. A 1/2 selector circuit of the front most column of a 1/8 selector circuit is controlled by three control lines for a connection/release signal S'0', an LSB(a0) and MSB(a2) of a selection control signal. That is, when S=0, the 1/8 selector circuit is released, the transfer gates of the front most stage are all turned off, and I0(0)-I7(0) data are not received. In this case, inputs A0-A3 are fixed to '1' by f1, f2. Thus, all inputs at points A0-A6 are fixed to '1' or '0', the power consumed by the A0-A6 is due to the leakage only and the power consumption is remarkably lowered.

Filed: 1994-07-15
Abstract: PURPOSE:To accurately detect oxygen concentration by introducing a plurality of standard gases containing known oxygen concentrations, calibrating reference gas detector part temperature and detector part temperature for gas to be detected, and detecting concentration of a gas to be detected. CONSTITUTION:The detector part is previously heated to about 600-800 deg.C, then a standard gas is introduced to the oxygen concentration detection meter, and an electromotive force E is read. After this operation is executed to at least two or more types of standard gases, reference gas detector part temperature T1 and detector part temperature T2 for gas to be detected are calculated (calibrated). The electromotive force E obtained by introducing the gas to be detected, oxygen concentrations P1 of the reference gas and calibreted temperatures T1, T2 are substituted into a formula E=(R)/(4F)[T1 ln (P1)-T2 ln (P2)] (where R is gas constant, and F is Faraday constant), and oxygen concentration P2 of the gas to be detected is calculated. Thus, since the standard gases are previously introduced thereby to accurately estimate the temperatures T1, T2, the oxygen concentration P2 can be accurately detected.

Filed: 1980-12-27
Abstract: PURPOSE: To rapidly operate motor stopping means, by providing pressure transmitting means for controlling the motor stopping means respectively in accordance with output side pressureof a servo valve and in relation to operation of input means of an oil hydraulic servo mechanism.  
     CONSTITUTION: When a control lever of a servo valve 10 is returned to its neutral position, a selector valve 13, operated interlocking to the servo valve, is also returned to its neutral position, and a pipe line to a brake device 20 is communicated to a tank. However, at this time pressure at the suction side of an oil hydraulic pump 1 rapidly rises to operate a control valve 11, then the servo valve 10 can not be reset immediately to its neutral state and remains in a state of selecting position. Here output side pressure of the servo valve 10 is taken out from a shuttle valve 22, and this causes a selector valve 14 to operate. Accordingly, when an oil hydraulic motor 2 is substantially in a stopping state, the selector valve 14 is reset to the neutral, and the selector valve 13 is also in neutral position, thus the brake device 20 can be operated.

Abstract: PURPOSE:To obtain large driving capability with small chip area without limiting the design of a power source by inputting the output of a logical circuit part which is connected to the 1st power source to a level shifting circuit and a driving circuit part. CONSTITUTION:The logical circuit part is driven by a power source 14 and the driving circuit part 6 which requires a high voltage and has large current consumption is driven by a power source 15. The level shifting circuit part 10 is driven by the serial circuit of the power sources 14 and 15 between VDD and VEE, so the maximum value of driving input voltage viewed from the driving circuit part 6 is the sum of the output voltage of the power source 14 and the output voltage of the power source 15. The current consumption of the level shifting circuit 10 is not large in general and there is not any special problem in the design of the power sources 14 and 15. Further, the power sources 14 and 15 are independent of the ground potential, so the grounding line of the system is utilized effectively and the designing of the power sources is easy.

Title: Switching system for video signal
Inventor: SAWADA KATSUTOSHI
IPC: H04N7/00
Filed: 1984-09-08
Abstract: PURPOSE:To detect a speech channel whose count result is maximum and constant and send an output through switching by comparing the level of each speech signal at every constant period and counting how many times a maximum level exceeds the constant value for every channel. CONSTITUTION:Speech signals inputted from speech input signal terminals 1a-1d have amplitude variation smoothed by smoothing circuits 2a-2d and sampled values are obtained by sampling circuits 3a-3d at every constant period T1. The sampled values lA-lD of the respective speech signals are applied to a level comparing circuit 4 to make a level comparison among respec tive channels, detecting a sampled value having the maximum level. Then, the maximum level for the maximum-level channel or a level 0 for other channels is inputted to level decision circuits 5a-5d to send '1' to counters 6a-6d when the level exceeds some level. When the value of the maximum level is found smaller than the constant value by the level decision making, it is ignored, so the influence of a low-level noise is removed.

Abstract: PROBLEM TO BE SOLVED: To provide a compact diode limiter which a breakdown voltage. SOLUTION: A dielectric substrate 3 is held between two divided casings 1 and 2 which contain a waveguide 4, i.e., the substrate 3 crosses the waveguide 4. However, a through-hole is formed at the fringe of the waveguide 4 to secure the conduction between both sides of the substrate 3, so that the waveguide 4 becomes continuous at a part of the substrate 3 that is exposed to the waveguide 4 excluding a metallic pattern and a necessary transmission line. The metallic pattern is formed so as to make the transmission line formed on the substrate 3 function as a post of a waveguide type diode limiter at the opening face side and also function as a center conductor of a waveguide/ coaxial converter at the short-circuited face side. Two electrodes of a PIN diode 9 are connected to the transmission line and a ground pattern which function as the posts respectively.  Then the reactance component of a control line is controlled via the stub cutting for the control of the reactance of the diode limiter that is done via a rotary screw.
