Abstract: PURPOSE:To always obtain optimum sensitivity with respect to various transmission speeds of information in optical communication by selecting a negative feedback resistor and a load resistor as an emitter-collector resistance of each bipolar transistor(TR) or a source-drain resistance of a field effect transistor(FET). CONSTITUTION:A photodetection section 1 is connected directly to a gate of an FET 2 as a 1st stage amplifier circuit. The drain of the FET 2 is connected to a power supply VDD via a drain-source resistor of the FET 3 and the source of the FET 2 is connected to ground. The FET 3 acts like a variable resistor by adjusting the gate voltage VG. Moreover, the source of the FET 9 as a variable feedback resistor is connected to the gate of the FET 2, the drain of the FET 9 is connected to the cathode of a diode 23 and the drain-source resistance of the FET 9 is adjusted by controlling a voltage VF impressed to the gate of the FET 9. Thus, even when the transmission speed is changed, the optimum band is obtained by adjusting the closed loop gain of the amplifier circuit and the feedback resistance.

Title: Filter cloth and its production
Inventor: OKADA HIDEMOTO
IPC: B01D39/08
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To obtain a filter cloth excellent in liquid permeability, fine particle catching properties, shape holding properties, and durability by a method in which crimped monofilaments are formed in a filter layer and fixed to a base layer, and the crimp ratio of the monofilaments and the elongation of the filter cloth are specified respectively. SOLUTION: A filter layer 2 is formed from crimped monofilaments 1, which are woven into a base layer 3 of fabric to be fixed. Fluid such as water is supplied in the direction A and filtered. The monofilaments 1, owing to being crimped, can have proper clearances to catch fine particles and simultaneously keep fluid permeability. The crimp ratio of the monofilaments is set up at 2-45% so that spaces between the monofilaments are kept properly to improve fine particle catching properties. In order to prevent the deformation of a filter cloth when strong tension is applied to the filter cloth, the elongation of the filter cloth is set up at 10% or below.

Title: Inspection method and device of vehicle brake device
Inventor: YUURUGEN BINDAA
IPC: B60T17/22
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To carry out the inspection of the emergency operation system of a brake as to an insoluble gas, by monitoring a variable which indicates the characteristic of the pressure rise in the operating condition when the pressure rises for the purpose of inspection, as to the tolerable limit value. SOLUTION: In order to control a hydraulic brake device 12, a hydraulic pressure is fed to an electronic control unit 10 from measuring devices 18 and 20 to measure the brake pressure, the brake moment, or the brake force, by input lines 14 and 16. The measuring value of the brake pedal operating level is fed from a measuring device 24 by an input line 22, while a regulating pressure value is fed by a line 64. Operating variables of the wheel speed, the car speed, and the like are fed from measuring devices 30 and 32, by input lines 26 and 28. The control unit 10 reads the measuring valve of a pressure sensor, and the measuring value of a pedal displacement sensor.  When the pressure value of a main brake cylinder is smaller than a specific value, and the pedal displacement is larger than a specific value, it is decided that there is an insoluble gas more than a tolerable amount in a brake system, and the control unit 10 outputs an alarm signal.

Title: Magnetic fluid seal
Inventor: FURUMURA KIYOUSABUROU
IPC: F16J15/34
Filed: 1982-02-10
Abstract: PURPOSE:To lengthen the life of a seal by a method wherein the magnetic fluid is caught and held by a magnetic force inbetween a dynamic pressure seal ring, equipped with a dynamic pressure generating groove, and a seal ring, being opposed thereto, and is rotated integrally with a shaft under pressing one of the seal ring. CONSTITUTION:When a shaft 2 begins to rotate, a magnetic fluid is concentrated toward the central part of a seal surface due to the pumping effect of a dynamic pressure generating groove 23a. According thereto, a sufficient lubricating film, generated by the magnetic fluid, is formed already at a very low speed (about 10-20rpm) simultaneously with the starting substantially and the seal rings 23, 25 are rotated under a noncontacting condition each other due to a fluid lubrication, therefore, the abrasion of the surfaces of the seal rings 23, 25 is very small. The resistance of the seal against the pressure during a normal operation arrives at about 5-200atm in accordance with the internal pressure at the central part of he surface of the seal, which is generated by the effect of the dynamic pressure generating groove 23a, therefore, a perfect rotary seal against the pressure of a wide range from a vacuum seal to a high-pressure seal may be effected easily.

Title: Semiconductor memory device
Inventor: IWAHASHI HIROSHI
IPC: H01L29/788
Filed: 1978-02-22
Abstract: PURPOSE:To establish the memory device possible for write-in and erase in a short time, by providing the control gate in open condition upward via the insulation film on the floating gate. CONSTITUTION:The n<+> layers 11 and 12 are placed on the p type Si substrate 11 and it is implanted in the SiO2 14 to provide the poly Si floating gate 15 and the control electrode 16 further upward. The control electrode is the poly Si layer of the cross section opening upward, and the distance between the part opposing to the electrode 15 and the substrate surface is smaller than that between the part of electrode 16 not opposing to the electrode 15 and the substrate. With this construction, the storage efficiency storing negative charge to the electrode 15 can sufficiently be made high and since the insulation film 14 between the electrode 16 and the substrate 11 is thick, the dose of ultraviolet rays reaching the electrode 15 through the film 14 is increased. Accordingly, the negative charge discharge time can be reduced and the erase of information is faster.

Title: Contour line drawing device
Inventor: NIWA NAOMASA
IPC: G06T3/00
Filed: 1987-01-28
Abstract: PURPOSE:To plot the contour lines in a short time by narrowing a level range of the image data to obtain each discrete level range and allocating the level corresponding to a background color to the levels set out of each level range. CONSTITUTION:The image data ID is stored in a main memory 4 via a CPU 2. The continuous level ranges are set between the minimum and maximum levels of the ID and each hue is allocated to the ID. A level range setting means 8 sets the upper limit value for each range. A CRT controller 32 supplies the ID given from the memory 4 to a level deciding means 12 for each dot via a shift register 6 and decides a specific level range set for each ID. Then a level resetting means 14 allocates a level to give a prescribed hue. The level range corresponding to each hue is gradually narrowed and these level ranges are set discretely. Thus a fixed level corresponding to a background color is allocated to each ID set out of the set range. In such a way, the contour lines are plotted in a short time.

Title: Vortex flow fan
Inventor: TANIGUCHI SEIICHI
IPC: F04D23/00
Filed: 1980-02-18
Abstract: PURPOSE: To increase the fan efficiency, by increasing the depth of an air passage gradually toward an air inlet port and an air outlet port on the side where the ports are located but decreasing the depth gradually on the opposite side.  
     CONSTITUTION: The clearance between an impeller 16 and an air passage 12 having an air inlet port 14 and an air outlet port 15 is increased gradually toward the ports 14, 15 on the side where these ports are located, but it is decreased gradually on the opposite side. From the inlet port 14 to a point A, a larger amount of air drawn from the inlet port 14 flows through the air passage 12 on the sides thereof where the inlet port 14 is located, but the air flow rate on the opposite side is small. On the other hand, in the region from the point A to a point B, a substantially equal amount of air is passed on both sides of the passage 12 and drawn and compressed in the revolving direction of the impeller 16. Further, from the point B to the outlet port 15, the air flow rate on the side of the port 15 is increased again but decreased on the opposite side. Then, air is discharged to the outside from the outlet port 15.  With such an arrangement, it is enabled to reduce the loss of air flow by eliminating turbulence of air flow near the ports 14, 15.
