Patent JP-H09223990-A (JP)
Title: Transmitter
Inventor: KAKO TAKASHI
IPC: H04B3/23
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To stably cancel echos by transmitting transmission signals to which reception signals are superimposed by a superimposing means through a hybrid circuit. SOLUTION: A reception carrier B is inverse-amplified by an invertible amplifier 56 and the reception carrier -B is outputted from the invertible amplifier 56. The reception carrier -B is inputted to the invertible amplifier 57 further and inverse-amplified and the reception carrier B are outputted from the invertible amplifier 57. The outputted reception carrier B is supplied through a resistor R to the input terminal of the invertible amplifier 54, superimposed with a transmission carrier -A and then, inputted to the invertible amplifiers 54 and 55. The signals are inverse-amplified in the respective invertible amplifiers and outputted through the hybrid circuit 53 to a line.  Since the output of the invertible amplifier 57 is outputted through the two invertible amplifiers 54 and 55 to the line, the phase of the reception carrier inputted to a modem and the phase of the outputted reception carrier are the same phase.

Filed: 1994-01-18
Abstract: PURPOSE:To inexpensively secure a form extractor that is light in weight and reusable by filling up resinoid foam in a constant-shape outer form body, while installing plural pieces of piercing ropeways in a central part, and attaching some extracting ropes to these ropeways. CONSTITUTION:Plural pieces of ropeways 4 are piercingly installed in the central part of a form extractor 1 made up of filling up resinoid foam 3 in a constant- shape outer form body 2. When some ropes 5 are installed in these ropeways 4 and the ropes 5 are pulled out, force is made so as to be equally improved on each rope 5. Then, this form extractor 1 is installed in a form in advance, and concrete is placed and, after the is removed, the form extractor 1 is pulled out, thereby forming some specified-form holes and recesses in the concrete. In this connection, the form extractor 1 is covered with a separate film or the like, through which form extraction can be facilitated. With this constitution, this form extractor 1 that is ease of handling and reusable is thus securable inexpensively.

Abstract: PURPOSE:To increase memory capacity which is handled and to improve a processing speed by operating a detecting means which is connected to a prescribed optical detecting means when the optical detecting means is irradiated with light by an optical means, and reading information recorded on a recording body and outputting it from an output circuit. CONSTITUTION:A recording disk 1 is rotated by a motor 15. While the recording disk 1 is irradiated with the detection light beam from a laser light source 3, a scanning part 8 is moved radially, for example, from the outside to the inside. At this time, the intensity of the light beam for detection which is made incident on a photodetector 7 varies in a pulse shape when crossing belt width (track) where an STM microchip 2 is mounted. This pulse is counted by a counter 13 to address a track according to input data from a keyboard 12. When the scanning part 8 is on a selected track, a CPU 11 controls a scanning part driving circuit 16 to stop a scanning part driving device 17. Consequently, the scanning part 8 is fixed on the selected track.

Abstract: PURPOSE: To save energy consumption of a blower, by wholly opening a control valve at the inlet of an aeration vessel and controlling a suction opening rate of a blower so as to keep a dissolved oxygen amount at a constant level.  
     CONSTITUTION: A dissolved oxygen amount in a sewage is detected by a meter 9, inputted to a dissolved oxygen controller 11 and fed to a flow rate controller 12. The controller 12 computes a valve opening rate proportional to an input signal 10, and outputs the opening rate to a blow rate control valve 6. At the same time, a blow rate is detected by a blow meter 8, and controlled at a constant level by the controller 12. On the other hand, the dissolved oxygen amount, an air blow rate signal 20 and an air pressure detected by an anemometer 13 are inputted to a controller 19 for controlling the operation of a blower, to generate an output signal 24 so that the blow rate control valve 6 will be opened to a possible extent. The opening rate of a control valve 17 is determined to keep the signal 24. Consequently, a pressure loss caused by the valve closing is lowered and energy consumption is saved.

Title: High pressure metallic vapor electric-discharge lamp
Inventor: ISHIGAMI TOSHIHIKO

Filed: 1983-02-28
Abstract: PURPOSE:To facilitate the installation of an emission tube into an outer tube bulb by using a shape-memorizing alloy to make a part of the mount members of the emission tube, and placing the emission tube in a given position by heating after the emission tube is installed in the bulb in a slant position. CONSTITUTION:An emission tube 4 is installed in the outer tube bulb 1 of a high pressure metallic vapor electric-discharge lamp. Its one end is pivotably connected to a conductive support 8a by means of a pivotable supporter 13a while the other end is freely rotatably connected to a conductive sliding member 14, attached to a support 8b, by means of a pivotable supporter 13b. In addition, a shape-memorizing alloy 15 which is in coil-like form in an atmosphere of high temperature and in stretched form at ordinary temperature is attached across the end of the support 8b and the holder of the emission tube 4. Therefore, even when the tube length of the emission tube 4 is larger than the neck 2 of the bulb 1, the emission tube 4 can be inserted in a slant position before its position is made vertical to the tube axis by increasing the temperature. As a result the installation of the emission tube 4 can be quite easily carried out.
