Title: Fluidized bed incinerator and operation thereof
Inventor: HANDA HITOSHI
IPC: F22B1/02
Filed: 1990-10-19
Abstract: PURPOSE:To perform smooth take-out of a non-combustible substance and to perform effective recovery of heat by a method wherein a partition wall is located in a direction extending at 90 deg. with a non-combustible substance take-out port, a heat exchanger is arranged in the partition wall, and a nozzle is mounted on a furnace floor surface. CONSTITUTION:Refuse 15 is dropped from a dust feeding device 16 to a fluidized bed part 2 for combustion. A partition wall 7 is built at the one side of the periphery of a fluidized bed part 2 in a direction extending at 90 deg. with a non-combustible substance take-out port 6. A heat exchanger 9 is located at the interior 8 of a partition wall between the partition wall 7 and a furnace wall, and a quantity of heat is recovered from fluidized sand. A quantity of a recovered heat is influenced by an amount of sand circulating through the interior 8 of the partition wall, the heat exchanger 9, and the heat transfer factor of the circulating sand. An amount of circulating sand is changed in a way that a nozzle is mounted on a furnace floor surface separably from the nozzle of a main fluidized air 11 and a quantity of air 12 circulating through a heat exchange part is regulated through opening and closing a valve 19 by means of an air amount controller 18. The factor heat transfer between the heat exchanger 9 and the circulating sand is changed in a way that a nozzle is arranged on a furnace floor surface and a quantity of heat exchange part air 13 is regulated through opening and closing of a valve 20. This constitution holds a furnace floor temperature at a constant value, effects effective recovery of heat, and performs smooth take-out of a noncombustible substance.

Title: Optical isolator
Inventor: SATO TADAKUNI
IPC: G02B27/28
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To decrease changes in isolation with temp. by controlling the temp. characteristics of a magnet which applies a magnetic field on a Faraday rotator to a specified range. SOLUTION: Generally, in order to improve changes with temp. or the like, the temp. characteristics of a material which directly acts (in this case, a CdMnTe compd. or CdMnHgTe compd.) are improved. However, relating to this material, improvement in the characteristics is not easy considering the wavelength characteristics, insertion loss, crystal growth, etc. Therefore, the temp. characteristics of a magnet which is used to apply a magnetic field on a Faraday rotator are controlled to a specified range so as to decrease the changes in isolation of an optical isolator with temp. The characteristics concerning to changes with temp. of the magnet to be used to apply a magnetic field are primarily the coercive force Hc and the residual magnetization Br. Therefore, the temp. change rate of the residual magnetization Br is controlled to 0 to -0.1%/ deg.C.  Thereby, deterioration of isolation due to temp. change can be reduced.

Title: Vibration sensing switch
Inventor: ITO NOBUO
IPC: H01H35/14
Filed: 1993-10-12
Abstract: PURPOSE:To make a piezoelectric element body operate and come to an ON state only to a shock of a prescribed limit or above by providing the body with a vibration absorber which can absorb the shock below the prescribed limit. CONSTITUTION:A switch 1 is formed by fitting a disk-shaped piezo-electric element 2 in a lifted manner on a disk-shaped base 5 of the same diameter with a doughnut-shaped expanded sponge 4 of the same diameter interposed. The sponge 4 transmits a large shock of a certain level or above to the element 2, while it absorbs a small shock of a certain level or below by a vibration absorbing capacity of its own. By the shock transmitted thereto, the element 2 is strained, generates electricity to operate as the switch 1 and comes to an ON state. When a load body being heavy relatively is provided on the element 2, acceleration applied to the load body is transmitted directly to the element 2. By adjusting the weight, position of fitting and others thereof, accordingly, regulation of sensitivity at the time of manufacture is made possible.

Title: Ventilator
Inventor: DAGURASU EFU DEBURIIZU
IPC: A61M16/00
Filed: 1987-11-04
Abstract: PURPOSE: To minimize delay time between the transmission of signal from a control means to a valve and the actual change of base part pressure by installing a pressure converter for measuring the pressure of base part gas and inputting the signals showing the base part pressure to the control means. CONSTITUTION: An exhalation phase is started by the opening of an exhalation valve 30 and the timing is decided by a controller 26. When the exhalation valve 30 is opened, gas inside the lungs of a patient 14 is automatically discharged to the atmosphere. The exhalation valve 30 is closed when the patient finishes exhaling. This ventilator 10 is provided with a positive final exhalation pressure mechanism so as to make an operator able to set how the pressure level of the base part gas is to be at the end of each respiration. During exhalation, the controller 26 compares the actual base part pressure with a predetermined pressure level, and when the base part pressure reaches the predetermined level, the controller 26 sends the signal 32 so as to make the valve 30 be closer to a closing position.  Then, the controller 26 controls the position of the valve 30 in terms of a closed loop so as to maintain the actual base part pressure to be equal to the predetermined pressure.

IPC: G02F1/1335
Filed: 1986-11-25
Abstract: PURPOSE:To obtain a panel which has superior color balance and excellent contrast by specifying the color array of picture elements, and coupling a line through which a select signal is supplied with elements to picture elements of the same color and varying the peak voltage of the select signal at every color. CONSTITUTION:When the color arrays of picture elements are as shown in a figure, picture elements of the same color connect with each other in one of a longitudinal, a lateral, and a slanting direction, so an image is seen very naturally. Further, picture elements 21-24 of the same color (Red) are connected by one line and picture elements 26-29 of another color (Green) are also connected by one line 210. Therefore, the peak voltage of a composite waveform can be made different at every color, so the signal is adjusted to its best voltage to obtain excellent black. Consequently, the contrast of the panel can be improved and the panel of good quality is obtained.
