Title: Flowmeter
Inventor: MASUTANI GIICHI
IPC: G01F1/20
Filed: 1986-03-28
Abstract: PURPOSE:To detect the flow rate of a fluid on the basis of pulse voltage, by a method wherein a suction pipe is allowed to communicate with the annular hole formed on a horizontal surface on the tangential line of said hole and a discharge pipe is allowed to communicate with the annular hole to provide a ball in a movable manner and an irradiation/light receiving means is provided to an optical circuit of which the optical axis is set on the locus of the ball. CONSTITUTION:The fluid flowing in from a total pressure introducing hole 2 passes through a pitot tube 1 to be guided to a suction take-out pipe 12. An annular hole 31 is always positioned on a horizontal surface and the fluid of the pipe 12 enters the annular hole 31 through a strainer mount part 21 but reaches a discharge take-out pipe 9 through a communication hole 26 and a lead-out hole 27 while allows a spherical ball 59 capable of tumbling in the hole 31 to tumble. The signal from a light emitting diode 35 is detected by a photodiode 41 while obstructed by the ball 59 tumbling in the hole 31 according to the flow rate of the fluid. By this constitution, the flow rate of the fluid is converted to the tumbling speed of the ball 59 tumbling in the annular hole 31 and the tumbling speed is converted to pulse voltage by an optical circuit to make it possible to detect the flow rate of the fluid.

Title: Color signal interpolation system
Inventor: NINOMIYA YUUICHI
IPC: H04N9/64
Filed: 1982-05-01
Abstract: PURPOSE:To improve the picture quality of a reproduced color picture without special signal processing at the transmission side, by interpolating a suitable interpolation color signal to a sampled color signal transmitted at a narrow band and making the signal band of a reproduced color signal broad the same degree as the luminance signal apparently. CONSTITUTION:A sampling luminance signal Y of time series is serial-parallel- converted into 6-sampling unit with a clock signal in sampling frequency fs at a serial parallel converter 1. The sampling values Y0-Y5 are operated at differential devices 2-1-2-5 to obtain differences Y1-Y5 to the sampling value Y0. Further, a sampling color signal C of the time series is applied to a register 6 operated with the clock signal in fs/5 to extract the color signal sampling value C0 corresponding to the sampling values Y0-Y5, and the value is applied to a differential device 7 to obtain a difference C5 between adjacent bands. Further, a divider 8, multipliers 3-1-3-4, and adders 4-1-4-4 are used to obtain the value C0 and interpolation color signals -C0--C5, and a reproducing color signal of a broad band the same degree as the luminance signal Y from a parallel serial converter 5.

Title: Retrieval system
Inventor: TAKAHASHI HIROSHI
IPC: G06F17/30
Filed: 1994-03-16
Abstract: PURPOSE:To retrieve data at high speed through the use of CPU having a TLB conversion mechanism. CONSTITUTION:Virtual addresses corresponding to retrieval keys inputted from an input part 1 by one to one are generated by a retrieval address generation part 2. TLB 20 is accessed through a memory access part 3 based on the virtual addresses. Since the plural entries of the groups of the virtual addresses corresponding to the retrieval keys and physical addresses corresponding to the virtual addresses are previously registered in TLB 20, the pysical addresses are read from a physical address generation part 51. Data to be retrieved is read from a retrieval physical address area in a main memory 30 by the physical addresses. Since the TLB mechanism which is originally provided in CPU is used, data can be retrieved at high speed with simple hardware.

Title: Method for measuring residence time of fluid within pipe
Inventor: INOUE SHIZUO
IPC: C02F1/00
Filed: 1991-04-05
Abstract: PURPOSE:To enable a residence time within a pipe to be measured accurately by pouring an uranin aqueous solution into a pipe at a starting point of a measurement section, sampling a liquid within the pipe at an ending point and then measuring an absorbance, and then obtaining a time difference between a time when the absorbance is the maximum and a time of pouring. CONSTITUTION:A pump for feeding a sewage with pressure is connected to a sewage pressure-feed ductwork 3 through a valve 5 and a flow meter 5 in a pump chamber 1. Also, a compressor 7 allows air to be fed to the ductwork 3 through an air pipe 8. A pump 4 is operated and sewage is allowed to flow and then air is fed from the compressor 7. Then, a uranin aqueous solution 15 is poured from a container 14 through a compact pump 16 and a hose 17. Then, a liquid within the pipe is sampled at 1-minute interval at a manhole 9 which is away from the pump chamber 1 by a certain distance and absorbance is measured and then a residence time within pipe from a time showing the maximum value is calculated. The uranin aqueous solution 15 shows a yellow- green fluorescent color and is harmless even if it is allowed to flow to the sewage.

IPC: G03G21/14
Filed: 1993-03-31
Abstract: PURPOSE:To switch the acting state of the device without setting time. CONSTITUTION:When the brightness of the external of the device is equal to or below a fixed value, an environment detecting CPU 62 decides that external environment is 'dark', and sets a 'sleepe state' where a normal feed part 32 is turned off and only an environmental change detection part 29 acts through the on/sleep switching signal line 37. On the other hand, when the brightness of the external becomes equal to or above the fixed value, the CPU 62 decides that the external environment is 'bright' and sets the feed part 32 to be on through the on/sleep switching signal line 37. Thus, the device gets in an ordinary use state and the main body 1 performs printing processing.
