Title: Flow rate measuring method
Inventor: UMAZUME KOSUKE
IPC: G01F1/86
Filed: 1985-12-05
Abstract: PURPOSE:To measure the flow rate of fluid with a small instrumental error even when the fluid contains much air by measuring the weight of the fluid as well as the flow rate and knowing the rate of liquid in the fluid, and correcting the indication of a flow meter. CONSTITUTION:The flowmeter 2 is connected in the middle of a duct 1 to be measured. Then, the flow meter 2 is supported in a free upward/downward moving state to the duct 1 to be measured so as to measure the weight of the flowmeter 2 by a scale 3. Then, the weight of fluid flowing through the flowmeter 2 is measured as well as the flow rate. The ratio of the liquid and air in the fluid is known and the measured value of the flowmeter 2 is corrected based on it to find the weight of only the liquid.

Title: Floppy disk device
Inventor: OKAWA YOSHIHISA
IPC: G11B19/12
Filed: 1989-10-24
Abstract: PURPOSE:To prevent a servo pattern recorded on a floppy disk which is loaded by mistake from being destroyed by deciding whether the servo pattern is recorded or not when the floppy disk is loaded. CONSTITUTION:When the floppy disk 1 is loaded, a spindle motor 6 begins to rotate and the output of a disk sensor 7 is inputted to a rotating speed detecting circuit 8. When the rotating speed of the motor 6 enters a specific range, the circuit 8 outputs a signal to a servo pattern(SP) detecting circuit 4 and a delay timer 9. The circuit 4 discriminates whether or not the playback signal of a magnetic head 2 contains an SP according to the signal from the circuit 8. When the SP is detected, an SP detection signal is outputted to a host device. When the SP is not detected before the signal from the delay timer 9 is inputted, the disk 1 is rejected. Consequently, the SP is prevented from being destroyed.

Title: Preventive method of weed growth on road facility
Inventor: SAWADA SHOJI
IPC: E01H11/00
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a herbicide and weeding works by installing a weed-growth preventive zone in proper thickness by small pieces in specified size to surface layer sections among flowering plants and trees planted at a central section such as a medium strip, a sidewalk-driveway separator, etc., in a public road, etc., and separator partitions on both sides. SOLUTION: Flowering plants and trees 2 are planted at the median strip of the central reserve and a sidewalk-driveway separator 1 of a public road, small pieces 4 consisting of the quality of materials such as stone, plastics, a metal, non-toxic industrial waste, brick, glass, etc., are placed on surface layer sections among the flowering plants and the trees 2 and separator partitions 3 on both sides in proper thicknes, and a weed-growth preventive zone 5 is mounted. The small pieces are easy to absorb solar rays, and reduce incidence by irregular reflection reaching soil. Accordingly, even when there are the seeds of weeds and moisture in the weed-growth preventive zone 5 and buds put forth, solar rays are absorbed by a small piece 4 layer and are not projected, and photosynthesis does not progress completely, thus preventing the growth of weeds.

Title: Optical element
Inventor: YUASA SATOSHI
IPC: G09F9/00
Filed: 1984-12-26
Abstract: PURPOSE:To obtain distinct images of high resolution by providing a liquid layer containing a liquid absorbing and discharging polymer, which discharges a liquid at a high temperature and absorbs the liquid at a low temperature, and a dyed liquid and a heating element which gives the thermal energy to this liquid layer. CONSTITUTION:When an infrared beam is not irradiated on a gel 4-2, the gel 4-2 is swollen as it is, and illuminating visible light 6-2 incident on the gel 4-2 passes through a gel containing liquid layer 2 without reflecting. When an infrared beam 5 is irradiated on a prescribed part of an infrared absorbing layer in accordance with an information signal or the like, the irradiated part absorbs infrared rays and converts them to heat to heat the gel, and a gel 4-1 discharges a solvent and is contracted. Therefore, illuminating light 6-1 is reflected and refracted by the gel 4-1, and the color of the dyed liquid is observed when this part is seen from the side of a transparent protective plate 3. When the temperature falls, the contracted gel 4-1 is restored to the original state and permits the light to pass through again.

Filed: 1984-12-26
Abstract: PURPOSE:To prevent false abnormality detection during an increase or decrease in printing speed by providing a printing speed monitoring circuit to a printed matter inspecting device which inputs each picture element of the pattern of printed matter and compares pattern information of every picture element with reference information. CONSTITUTION:A printing form 3 supplied by a rolled take-up form 2 is printed in four colors on its top and reverse surfaces by a printing part 1 and carried. Pattern information IS on the form 3 is scanned by a detecting part 4 on the basis of timing pulses TP from a rotary encoder fitted to the plate drum or blanket, and the scan data is inputted to an abnormality decision circuit 6. An abnormality signal ES outputted by the circuit 6 is transferred to the speed monitoring circuit 7.

An addition absolute value circuit 13 calculates the quantity of speed variation of the variable Vn and a comparing circuit 14 compares it with a reference value from a shift circuit 12 and outputs a constant speed signal TS when the difference is within a permissible range. Thus, false abnormality detection in an increase or decrease in printing speed is prevented.
