Title: Optical echo microscope
Inventor: UCHIKAWA KIYOSHI
IPC: G01N21/27
Filed: 1991-02-25
Abstract: PURPOSE:To make it possible to obtain the data concerning to the difference in physical and chemical properties of a sample by measuring the optical-phase alleviating time of the sample. CONSTITUTION:A light source means A supplies the light having space coherence which can be regarded as a point light source on an image plane and the specified time coherence from a light source 1. A light-modulation optical system B splits the light with a light splitter 2. One light is delayed by a specified time with a delaying means 4. The other undergoes phase modulation at a specified frequency with a light modulating means 5. These lights are synthesized with a light synthesizer 3. A cofocal scanning microscope C guides the light on a test specimen 20 with an illuminating optical system, and a spot is formed. Scanning is relatively performed with a scanning means. The light guided from the substance is detected with a photodetector 15. The modulated part which is even-number times the modulating frequency in the means 5 is extracted with an electric-signal processing part 40 from the output signal of the photodetector 15. Thus, the optical-phase alleviating time of the sample is obtained based on the change in optical echo caused by the change in difference between the lengths of the light paths of two light beams. The difference in physical properties can be made clear based on the change.

IPC: F22B37/42
Filed: 1995-02-20
Abstract: PURPOSE: To provide the title apparatus which prevents implosion surely. CONSTITUTION: Pressure in a furnace 21 is properly held by controlling the opening of a moving blade 6a for a forced draft fan 6 and a moving blade 18a for an induced draft fan 18. When a signal to cut-off a main fuel is outputted from a boiler control system, the opening of the moving blade 6a is held in that state and the opening of the moving blade 18 is throttled. At the same time, the signal is outputted from a MFT signal transmitter 7 and a solenoid 31 is excited through an OR circuit 33. A controlling air line 30 is switched, an opening and closing valve 29 is opened, and outside air is thrown into the furnace 21. Since this process is carried out simultaneously with the output of the signal to cut off the main fuel, the outside air is quickly thrown thereinto and implosion can be surely prevented.

Title: Acoustic echo suppressing device
Inventor: SHINAGAWA NORIAKI
IPC: H04B3/23
Filed: 1989-02-10
Abstract: PURPOSE:To suppress echo even at the time of input of noise other than voice from a speaker to a microphone by subtracting artificial echo and artificial noise from the output signal of the microphone and transmitting the subtraction result to the opposite party. CONSTITUTION:When sounds other than speaker's voice or the like are inputted to a microphone 11, echo due to noise of a noise source 13 is suppressed because the artificial noise from an impulse response estimating circuit 19 is subtracted from the output signal of an A/D converting circuit 14 by a subtracting circuit 21. Since the artificial echo from an impulse response estimating circuit 20 is subtracted from the output signal of the subtracting circuit 21 by a subtracting circuit 22, sounds M2 passing round from a speaker 18 to the microphone 11 are suppressed. Thus, echo is suppressed though noise other than voice from the speaker 18 is inputted to the microphone 11.

Title: Gas treating method
Inventor: RICHIYAADO UIRIAMU WATOSON
IPC: B01D53/52
Filed: 1992-02-19
Abstract: A gas stream comprising hydrogen sulphide is preheated in a heat exchanger 2. Part of its hydrogen sulphide content is burnt in a furnace 6 to form sulphur dioxide and water vapour. Pure oxygen or oxygen-enriched air is used to support combustion. The sulphur dioxide reacts with residual hydrogen sulphide to form sulphur vapour and further water vapour. The sulphur vapour is removed from the gas stream in a condenser 14. The gas stream is then divided into first and second subsidiary streams. The hydrogen sulphide content of the first subsidiary stream is totally converted to sulphur dioxide in an incinerator 16 using pure oxygen or oxygen-enriched air to support its combustion. Water vapour is then removed from the first subsidiary stream in a condenser 20, and the resulting gas stream now relatively rich in sulphur dioxide, is recycled to the furnace 6. The second subsidiary stream is subjected to a plurality of stages 26 of catalytic reaction between hydrogen sulphide and sulphur dioxide to form further sulphur vapour which is removed therefrom. <IMAGE>

IPC: G06F3/12
Filed: 1991-01-31
Abstract: PURPOSE:To reduce the burden of users by deleting the registered forms if an idle area is short when a new form is registered in a form memory and then registering the new form in the idle area obtained by deleting the registered forms. CONSTITUTION:A form memory securing means 24 of a data processor 2 compares the size of the form whose registration is instructed from a CPU 1 with the size of an idle area of a form memory 31 of a printer controller 3 to decide whether the form can be registered or not. If not, a form memory deleting means 26 deletes continuously the registered forms of the memory 31 until the means P4 decides that the form can be registered. When the means 24 decides that the form can be registered, a form register means 25 registers the form instructed by the CPU 1 into the memory 31. Thus the burden of the users can be reduced.

Abstract: PURPOSE:To enable a force transmitted to an oscillation bumper, to be reduced at the time of drawing out a pile by fitting the oscillation bumper into a space between parallel links in an oscillating pile drawing bench, and by connecting inclined links respectively to the upper ends and lower ends of the bumper. CONSTITUTION:To the upper ends of parallel links 1, 1a holding an oscillation bumper 6 between them, upper inclined links 2, 2a are pin-connected, and to the lower ends, lower inclined links 5, 5a are pin-connected, and a shackle 4 to be hooked at an upper section and the shackle 4 for suspending an oscillation generating machine 10 at a lower section are pin-connected respectively via shackle supporting bodies 3.

IPC: H01L21/321
Filed: 1994-03-02
Abstract: PURPOSE:To secure the reliability of connection at bump electrodes by preventing solder from coming into a protective film and maintaining the height of the solder bumps. CONSTITUTION:On a substrate 1, an interconnect pattern 11 is formed. Then, on the interconnect pattern 11, adhesive metal 12 is formed. The adhesive metal 12 is formed in the shape of, for example, a ring, so that the interconnect pattern 11 may be exposed at the center of the adhesive metal. In the center opening of the adhesive metal 12, a post land 13 is formed, whose bottom is connected to the interconnect pattern 11. The top of the post land 13 becomes a bump electrode. Then, a protective film 17 is so formed that the top of the post land 13 may be exposed. The adhesive metal, being formed between the post land 13 and the interconnect pattern 11, prevents solder on the bump electrode from penetrating the interconnect pattern 11. Furthermore, since the protective film 17 is formed on these layers and the protective film 17 and the adhesive metal adhere tightly to each other, the solder is prevented from penetrating the interconnect layer.
