Title: Orientating system of break point of optical fiber
Inventor: TSUKADA KAZUMASA
IPC: G01M11/00
Filed: 1983-07-05
Abstract: PURPOSE:To orientate surely a break point of an optical fiber by propagating two kinds of light, which have wavelengths different in transmission speed, in the optical fiber and detecting a difference between points of time of breaks of these two kinds of light which is caused by a break of the optical fiber. CONSTITUTION:Light sources 1 and 2 generate continuous light having wavelengths lambda1 and lambda2, respectively. These wavelengths lambda1 and lambda2 are different in transmission delay time per unit length in an optical fiber 100. These two kinds of light are synthesized by an optical coupler 3 and are transmitted to the optical fiber 100. Two kinds of light propagated in the optical fiber 100 are separated to optical components having wavelengths lambda1 and lambda2 by a wavelength separator 4, and they are converted to electric signals 51 and 61 by photoelectric transducers 5 and 6. Electric signals 51 and 61 are inputted to a time difference detector 7, and a time difference signal 71 is outputted if a break occurs.

Title: Averting device for abnormal upward and downward movement in upward and downward moving device for lance
Inventor: MORI ATSUSHI
IPC: C21C5/46
Filed: 1981-08-06
Abstract: PURPOSE:To prevent the danger due to abnormal upward or downward movement in a converter or the like by detecting the speed of a lance when the lance moves upward or downward and stopping the upward or downward movement of the lance when said speed exceeds a set speed. CONSTITUTION:In the stage of bringing a lance 1 down into a converter or pulling it up, the lance is first moved downward and upward at a high speed and just before the installation position, the speed is dropped and the lance is stopped in the specified position. The initial high speed is detected with a moving distance detector 20 via a driving  device 2 and a speed change gear 3, and the output signal thereof is differentiated with an operator 24. The output thereof is inputted to an outputting device 25 for a high speed stopping signal. Here, the signal is compared with an upper limit speed signal P3 during high speed movement, and when the speed of the lance 1 is higher than the upper limit speed, a signal is outputted to a speed controller 23, which stops the driving device 2 for the lance, thereby preventing the lance 1 from entering the furnace at an abnormal descending speed. The same holds true of the ascending of the lance 1. of the lance into the molten steel by breakage of a wire rope owing to the ascending speed of the lance are prevented.

Title: Liquid crystal display device
Inventor: UENO YOSHIKI
IPC: G02F1/13363
Filed: 1993-05-26
Abstract: PURPOSE:To reduce external light reflection and prevent the luminance of the display screen from decreasing by forming a reflection preventive film (AR coat) on the display surface and forming AR coats on both the surfaces (front surface and back surface) of a protection plate. CONSTITUTION:The protection plates 10 are provided with reflection preventive films 11 and 12 with AR coated. A liquid crystal panel 20 has a linear polarizing plate 21 and its front surface is AR-coated to provide with a reflection preventive film 13. When external light Lo is made incident at a certain angle of incidence, reflection La on the front surface of the protection plate 10 is greatly reduced by the reflection preventive film 11. When the protection plate 10 is made of acryl, the surface reflection rate becomes 0.2-0.3% when AR coating is performed for 4% at the time of no working. Reflection Lb and reflection Lc are both reduced to about 0.2-0.3% and the total reflection rate is below about 1% although the total reflection rate of a conventional liquid crystal display device which is not provided with the reflection preventive film 11 is 11-12%.

Title: Semiconductor device
Inventor: SUZUKI HIROSHI
IPC: H01L21/768
Filed: 1990-05-14
Abstract: PURPOSE:To obtain a semiconductor device having a multilayer wiring layer which eliminates an increase in an electrostatic capacity even in the case of high integration and high density, prevents delay of an operating speed, and noise, and obtains a stable operation by forming at least one of wiring layers in a direction other them parallel or vertical to the other layer wiring direction. CONSTITUTION:In a semiconductor device having three layer aluminum Al wiring, the wiring is so formed as to form angles of 120 degrees among Al 1, Al 2 and Al 3 layers. Thus, vertical superposition of upper and lower wiring in parallel can be avoided to prevent generation of electrostatic capacity of the wiring. Accordingly, since the electrostatic capacity of the wiring can be prevented, the respective layer wiring can be formed without almost considering a delay time. Therefore, even if a semiconductor integrated circuit is highly integrated and enhanced in density, its operating time is not delayed.

Title: Control system for address coincidence interruption
Inventor: SHINKAI MICHINORI
IPC: G06F11/28
Filed: 1988-05-20
Abstract: PURPOSE:To efficiently simulate the address coincidence stop of a real computer with a virtual computer, etc., by suppressing the action of a stopping means due to an output signal to indicate coincidence, and issuing a prescribed interruption with the output signal to indicate the coincidence when a prescribed mode is set. CONSTITUTION:A means exists which stops the action of a central processing unit 41 by means of the output signal to indicate the coincidence of address coincidence detecting parts 17 and 16. For example, when a virtual computer (VM) mode is not set, a system interruption generating part 43 to be provided in a central processing unit 41 is stopped by setting a stop latch 32 by means of a signal to indicate the address coincidence in the same way as usual, while, at the time of a VM mode, when the output signal to indicate the address coincidence is produced, the part 43 suppresses the setting of the stop latch 32, and generates the prescribed interruption according to the designated bit of a control register 44. Thus, even the VM can use an address stopping function.

A shock current is made to flow to an exciter coil in a hitting inspection probe 5, and a vibration sound is detected by a microphone. A high-frequency region and a low-frequency region which are outside an estimation vibration region are removed from the vibration sound by a frequency analysis part 11. After that, the natural oscillation frequency of the can 2 is extracted from its histogram so as to be sent to the microcomputer 10. Therefore, by using information on a characteristic curve, between the pressure inside the can 2 and the natural oscillation frequency, which is stored in the RAM or the like, a proper pressure inside the can 2 can be judged.
