Title: Emergency small-scale underground water storage tank device
Inventor: TAKAHASHI IWAO
IPC: E03B11/14
Filed: 1995-05-15
Abstract: PURPOSE: To store clean water nearby and supply the water definitely in emergency. CONSTITUTION: A water storage tank 2 is buried under an underground city water service pipe 1. A vertical water supply pipe 4, whose upper end 4a is mounted with a check valve 5 and exposed near the ground and whose lower end 4b is located inside the storage tank 2, is branched to the upstream side of the city water service pipe 1 shut-downed with a shut-down valve 3 while a vertical suction pipe 6, whose upper end is mounted with a check valve and exposed near the ground and whose lower end is located inside the water storage tank 2, is branched to the downstream side of the city water service pipe 1 respectively. Furthermore, a supply pipe 8 is installed to the city water service pipe where the upper end 8a of the supply pipe 8 is mounted with a supply faucet 9 and exposed near the ground and the lower end 8b is located inside the water storage tank 2.  During normal operation, water is fed to the water storage tank 2 from the upstream side of the city water service pipe 1 by way of the vertical water supply pipe 4 during normal operation time while it is bypassed to the downstream side of the city water service pipe 1 by way of the vertical suction pipe 6 and each check valve 5 is arranged to be in a state in which water pressure is closed. When water supply is cut off, the atmospheric pressure is arranged to be in a natural open state from each check valve 5, thereby preventing the water storage tank 2 from overflowing and sucking up the stored water by the supply faucet 9 of the water supply pipe 8.

Title: Ultrasonic motor
Inventor: IMASAKA YOSHINOBU
IPC: H02N2/00
Filed: 1988-06-08
Abstract: PURPOSE:To reduce a wearing amount by forming a moving element of a sheetlike molded piece containing 50wt.% or more of fluorocarbon polymer, and so composing it as to incorporate a frictional contact part with a vibrator therein. CONSTITUTION:An ultrasonic motor is composed by bringing a moving element 3 into pressure contact with a platelike vibrator 2 in which a platelike piezoelectric element 1 is mounted. The element 3 is formed of a sheetlike molded piece containing 50-90wt.% or less of fluorocarbon polymer, and so composed as to incorporate a frictional contact part with the vibrator 2. The vibrator 2 is normally formed of a metal material, such as a stainless steel material having a small vibration attenuation. Thus, it does not substantially decrease and deteriorate various performances of the motor due to the wear but smoothly rotates.

Filed: 1980-10-09
Abstract: PURPOSE:To work the work without moving the same at every working point by selecting and introducing laser light successively to plural fiber optical systems corresponding to the working points of the work, and loading the work in the direction and position. CONSTITUTION:The work 11 is beforehand carried by a turntable 13 to the working position where all the working points obtain optimum working conditions. The laser light 2 from a laser oscillator 1 is beforehand adjusted so as to be made incident to 7 of, for example, six fiber optical systems 6, and when the stop signal of the turntable 13 is received, the laser oscillation is carried out. The laser light 2 passes through the fiber optical system 7 and works one point at the working point of the work 11.

Title: Terminal calling method
Inventor: FURUYA YUKITSUNA
IPC: H04W84/02
Filed: 1986-06-19
Abstract: PURPOSE:To prevent registration from a terminal equipment and to prevent much increase in call traffic even with the increased number of zones by collecting moving information of each terminal equipment between zones as transition probability when an exchange station applies each communication and deciding a zone selectively based on the said transistion probability and applying sequential calling. CONSTITUTION:When a call comes from a caller to a terminal equipment K, an exchange at first reads the preceding communication zone of the said terminalequipment from a memory. Suppose that the equipment makes preceding communication at a zone X, the exchange reads the zone transition probability Pk(X,I) of the equipment K and compares a threshold value Q(J) with the transition probability Pk(X,I) at each zone I. Then zones having larger transition probability pk(X,1) than the threshold vlaue Q(J) only are called. If no reply comes regardless of elasped time and not all zones are called yet, the exchange changes the threshold value into Q(2), and calls zones whose transition probability is larger than the value Q(2). In this case, the zones already called are excluded.

Abstract: PURPOSE:To prevent the decrease in S/N ratio at a low output signal level, by driving final stage gates and a reset gate at a frequency, which is one over integer number the driving frequency of the first and second gate electrodes. CONSTITUTION:Final stage gates 15a and 15b and a reset gate 19 are driven at a frequency, which is one over integer number the driving frequency of the first and second gate electrodes. Thus, signal charges transferred by a plurality of transfer electrodes are combined and a large output signal is obtained. In this way, an S/N ratio is improved. For example, when the frequency of transfer pulses phi1' and a reset signal RS is 1/2 the transfer pulses phi1 and phi2, the electric charges beneath two transfer electrodes are simultaneously read in one reading cycle. The level of output signals 23, 23... becomes twice. The rate of the output period of the signal with respect to a thermal noise component becomes large. By reducing the frequency band to 1/2, the noise also becomes approximately one half, and the S/N ratio can be improved.

Abstract: PURPOSE:To increase the efficiency of a boiler, by keeping a fluidization in fluidized-bed without increasing the air ratio, by flowing part of exhaust gas from the boiler into combustion air, passing through a bypass passage, at the time when loading to the fluidized-bed boiler is low. CONSTITUTION:A part of an air duct 1 on the upstream side of a forced draft fan 2 is connected to a part of an exhaust gas duct 7 on the downstream side of an induced draft fan 8 by a bypass dust 9. When loading to a boiler 3 is decreased, a controlling damper 11 is opened, at the same time the flow rate of exhaust gs duct 7 is throttled by operating a controlling damper 10 to the closing direction in accordance with the decrease of loading. Then part of exhaust gas is to be mixed with the combustion air flowing through the air duct 1, by way of the bypass duct 9, and the rate of mixed flow of combustion air and exhaust gas which is to be supplied to the boiler 3 is able to be kept as equal as the rate of combustion air in the normal operating time. Accordingly, a fluidized-bed 6 can be kept fluidiezed at the time of low loading without heightening the air ratio, so that the efficiency of the boiler at the time of low loading can improved.
