Title: Surface floating water tank
Inventor: KOGA KENICHI
IPC: G01F15/00
Filed: 1982-07-07
Abstract: PURPOSE:To uniformize a flow velocity distribution immediately before a model by arranging a porous plate on the upstream side thereof so that there are larger openings from top to bottom crossing a passage in a surface floating water tank adapted to visualize the flow about the model. CONSTITUTION:A porous plate 4 in which holes 4a are made larger from top to bottom are arranged on the upstream of a model M in a passage 1 perpendicular to the water flow. At this point, the flow immediately before the porous plate 4 indicates the flow velocity distribution affected by a boundary layer as shown by the arrow A. But the passage through the porous plate 4 makes the flow velocity distribution almost equal in the vertical way as shown by the arrow B. Thus, the even flow velocity distribution can be obtained immediately before the model thereby assuring correct visualized results.

Title: Automatic frequency controlling system
Inventor: MISHIRO TOKIHIRO
IPC: H04B7/208
Filed: 1982-07-07
Abstract: PURPOSE:To obtain an AFC system requiring no special pilot signal, by converting the frequency of a PSK modulated wave with an output signal of a VCO, detecting a frequency error signal by a frequency discriminator after extracting the nonmodulated part of the frequency converted signal through a BPF, applying the extracted frequency error signal to a peak value holding integrator to hold the peak value and then applying the peak value to the frequency control terminal of the VCO to set the frequency of the output signal of a frequency converter at a fixed level. CONSTITUTION:A received PSK modulated wave is mixed with the output signal of a VCO12 by a frequency converter 8 to perform a frequency conversion. The frequency converted signal extracts the signal of a nonmodulated part of a figure A by a BPF9. When the signal of a nonmodulated part of a figure B is passed through a frequency discriminator 10, the voltage shown by (C) or (D) is delivered. The peak value of the voltage is held at a peak value holding integrator 11 to obtain the voltage shown by (E) or (E'). This voltage is applied to a frequency control terminal of the VCO12, and the frequency of the VCO12 is controlled to set the output voltage of the integrator 11 at 0. The error frequency component of a PSK modulated wave is corrected by the output frequency of the VCO12. Thus the frequency of the output signal of the converter 8 is set at a fixed level and undergoes AFC.

Title: Method for controlling flow rate of offgas in pressure- swinging adsorption apparatus
Inventor: FURUTA HIROTAKA
IPC: C01B3/56
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To keep the generation amount of offgas to a constant level as far as possible and to suppress the pressure variation of an offgas storage tank by stepwisely opening an upstream-side valve of the offgas storage tank in the blow-down stage of each adsorption column of a three-column pressure-swinging adsorption apparatus for the purification of hydrogen. SOLUTION: The present process is started from a step comprising the adsorption in a column A, the reduction of pressure in the column B and the purge in the column C and followed by a step comprising the adsorption in the column A, the pressure equalization in the column B and the pressure equalization in the column C. The valve B4 is switched from opened state to closed state while continuing the adsorption operation in the column A, the valve B5 is switched from closed state to opened state to switch the pressure equalization in the column B to the blow-down stage, the valves W, C4 are changed from open to close and the valves W, C3 are opened to switch the pressure equalization in the column C to the step to increase the pressure with generated hydrogen.  The opening of the valve Y is increased stepwise in the above process to eliminate the increase in the reduced pressure in the blow-down stage of the column B and to keep the inner pressure of the offgas storage tank T to a nearly constant level.

Title: In-dashboard monitor for vehicle
Inventor: HATAKEYAMA HIDEYUKI
IPC: G09G5/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To allow only a predetermined person to operate the monitor housed inside a vehicle when operating it outside, thus preventing theft in which the monitor otherwise might be easily removed since mounted outside. SOLUTION: In this monitor, a fingerprint sensor 32 is installed above a monitor 3 photographing a fingerprint of a finger 42 by a CCD image pickup device 41. User's fingerprints of a first, middle, and third fingers and the like are registered in advance to a fingerprint registering portion 44. Then, detected fingerprints are collated to examine if they match the registered ones in a fingerprint collation portion 45. If not, it is impossible to take the monitor out. Furthermore, when a first finger's fingerprint matches to the registered one, for example, a signal is output to a monitor opening/closing portion 47. Similarly, when a middle finger's fingerprint matches the registered one, a navigation system works and shows the way to the person's home. When a third finger's fingerprint matches the registered one, still more functions other than the above are also in effect.

Title: Gas laser oscillator
Inventor: KIMURA MASAO
IPC: H01S3/081
Filed: 1986-05-26
Abstract: PURPOSE:To eliminate superposition from laser beams by providing reflection polarizing member at passing courses of laser beams between an output mirror and rear mirror, while the above members hold a nature which makes incident beams reflect in opposite directions to incoming directions of the incident beams irrespective of inclination angles of reflection polarizing parts to incident beams. CONSTITUTION:Output powers of laser beams LB are enhanced by causing the laser LB to be bent in a discharge area E by a first reflecting surface 7A and a second reflecting surface 7B of reflection polarizing members 7 as well as the first reflecting surface 9A and the second reflecting surface 9B of the reflection polarizing members 9. In other words, as the laser beams LB move back and forth several times along the courses comprising one course between an output mirror 3 and rear mirror 5 via the reflection polarizing members 7 and 9 and the other course between the rear mirror 5 and output mirror 3 via the reflection polarizing members 9 and 7, the output mirror 3 permits a portion of the laser beams LB to be oscillated outside the discharge area E. Thus, superposition of laser beams is overcome by the arrangements of the reflection polarizing members and the like.
