Title: Device to detect occurrence of flashback to premixture combustor system
Inventor: BROWN DALE MARIUS
IPC: F23R3/00
Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To rapidly detect the occurrence of flashaback in order to perform a stop before a combustor is damaged by sensing the occurrence of the flashback by using a plurality of optical fibers and photodetectors. SOLUTION: A combustor 1 contains a plurality of flame nozzles 12a-12e to generate flame. The flame nozzles 12a-12e are monitored by using fiber optical elements 24a-24e containing optical fibers through which a light signal is sent to photodetectors 14a-14e. The photodetectors 14a-14e feed an electric signal to a multiplexer 18 and the multiplexer 18 transmits data to a signal processor 20 before the multiplexer is operated by a gas turbine controller and monitor 22. When light is detected by the photodetector 14a-14e at a level to indicate the presence of flame in a test region where no flame is present, the information is transmitted to the controller and monitor 22 through the signal process 20 and this way turns OFF the combustor 1.

Filed: 1979-12-21
Abstract: PURPOSE: To correct the delay time generated by connected cables, unit by unit, by transmitting a check timing signal up to the units in the same manner as for a control signal and returning it to the testing apparatus side.  
     CONSTITUTION: Units 14W16 packaged with printed circuit boards 25 as the devices to be tested are housed in an aging chamber 2 and the respective units 14W 16 are connected to a testing apparatus 1 by means of cables. After the test data are sent to each unit through a control line 30, they are returned to the testing apparatus 1, and the signal from a timing signal generating part 18 is also returned by passing through the inside of the units. By the timing signal thereof, the test data are compared in a comparator 20. Hence, it may be made into the check timing signal corrected of the delay time of the signals by the cables and the need for making the unit-by-unit timing signals may be eliminated.

Title: Ultrasonic flowmeter
Inventor: NAWA MOTOYUKI
IPC: G05D7/00
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To constitute the entirety of an ultrasonic flowmeter having a flow interrupting function compactly by arranging a flow control valve in the form of a straight tube on the upstream side of a flow measuring section. SOLUTION: A first ultrasonic oscillator 7 is disposed on one side of a flow measuring section 6 while a second ultrasonic oscillator 8 is disposed on the other side of the flow measuring section 6. A flow control valve 11 comprising a fixed opening plate 9 and a sliding opening plate 10 are arranged in the form of a straight tube on the upstream side of a flow measuring section 6 and a straightening 27 is interposed between the flow control valve 11 and the flow measuring section 6. When a seismic sensor 25 senses an abnormal vibration due to earthquake or the like, a control section 26 operates to drive a solenoid 13 thus closing the opening plate 10. Consequently, the flow from the direction of an arrow (a) is blocked.  The entire channel can be constituted into a straight tube by combining the flow measuring section 6 and the control valve 11 and the entirety of flowmeter can be made compact. Furthermore, the length can be shortened in the flow direction by driving the control valve 11 with a solenoid.

IPC: B41J29/38
Filed: 1978-12-26
Abstract: PURPOSE: To make a printing control signal producing apparatus compact and economical, by reducing the number of component parts and thereby preventing that capacity of the apparatus be increased or that its structure becomes complicated, by employing an arrangement in which signals for indicating print starting position and for stopping operation of motor are produced from a single print synchronizing signal producing apparatus.  
     CONSTITUTION: When light emitted from light emitting transistor element 7, intermittently interrupted by means of disk 10 and shielding means 12, it received by light receiving transistor element 8, it is converted into electric signal of on-off pulse wave-form. Then, it is shaped into rectangular wave by the following transistor 18 and converted into pring synchronizing signal 1 by means of inverter IC20. This signal 1 is afforded to timer circuit 21 which can be re-triggered. In the above arrangement, since value of set time in circuit 21 is selected to be larger than the pulse period of signal 1, it is enabled to start printing operation in stable manner and to obtain motor stopping signal 2 if revolutional speed of printer motor for producing print synchronizing signal or fluctuation is caused to the same.

Title: Nonvolatile semiconductor memory device
Inventor: OKAWA MINORU
IPC: G11C16/02
Filed: 1992-06-24
Abstract: PURPOSE:To provide a nonvolatile semiconductor memory device wherein the erasure time can be shortened during the test operation of a flash memory. CONSTITUTION:Whether a memory cell array 1 has been erased or not is judged by a judgment circuit. According to the judgment result of the judgment circuit 30, the judgment circuit 30 outputs a nonerasable-mode signal when the memory cell array 1 has been erased, and the judgment circuit outputs an erasable-mode signal when the memory cell array 1 has not been erased. In addition, according to a control signal from the outside, a mode-signal generation circuit 40 generates an erasure-pulse control signal irrespectively of the output of the judgment circuit 30. Consequently, an erasure operation in an ordinary operation is not verified in a test operation from the start of the erasure operation up to immediately before the completion of the erasure operation. As a result, the erasure operation can be finished earlier than the ordinary operation, and the erasure operation in the ordinary operation is verified by the completion of the erasure operation after that. As a result, the title memory device has a sufficient margin and can be erased without being erased excessively.

Filed: 1981-10-19
Abstract: PURPOSE:To transduce electric energy into motional energy efficiently by fixing a cantilever driving coil to a magnetic yield yoke in a VHD signal pickup device for information disks. CONSTITUTION:Cantilever driving coils 8a, 8b, and 9 are fixed to the end parts and center part of a magnetic yoke 10 which is formed nearly in a channel shape. Magnetic flux produced by a permanent magnet 3 passes through the magnetic yoke 10 having small magnetic resistance to converge to internal sides of the driving coils 8a and 8b close to the magnet 3 while magnetic flux interlinked with the opposite external coil sides where forces are generated in the opposite direction is reduced greatly. Therefore, the magnetic flux by the magnet 3 is utilized efficiently as a force driving a cantilever 2. Further, the cantilever 2 is driven by the cantilever driving coil 9 efficiently at right angles to the shaft of the cantilever 2 and in the plane formed by an elastic support 5.

Abstract: PROBLEM TO BE SOLVED: To decrease physical burden of a patient by deforming the bottom part of the surface of a seat back in accordance with the posture of the seat back. SOLUTION: A freely elastically deformable metal sheet 31 is provided on a seat back frame 17. A link 33 is provided to a movable rod 18B of a hydraulic cylinder 18 for inclining the seat back frame 17 and when a pushing lever 32 is operated by rotation of this link 33, at ordinary time, the pushing lever 32 pushes the metal sheet 31 from the back side to deform elastically it to the front side. Therefore, the bottom part of the surface of the seat back 9 is curved gently to the front side. When the seat back frame 17 is rotated to the back side to make it approximately horizontal, the pushing lever 32 release the pushing condition of the metal sheet 31. Therefore, the metal sheet 31 is elastically returned back to a flat sheet-like state.  In addition, the bottom part of the surface of the seat back 9 is made flat to form approximately the same plane as the surface of the seat bottom 8.
