Title: Airship
Inventor: KURIBAYASHI SADATOMO
IPC: B64B1/00
Filed: 1989-11-24
Abstract: PURPOSE:To obtain an airship which can take off and land in a small space by composing a gas container to be long vertically and almost of a similar size horizontally to the horizontal size of a main body part to float. CONSTITUTION:Compressed air of a sufficient volume is put into an air bag 16 in a main body part to float 4 to make the buoyancy of a gas container 2 small to stay on the ground, and the volume of the air bag 16 is reduced by removing the compressed air properly to increase the volume of helium gas to float and take off. In this case, when a propeller 22 is actuated to be directed up, a larger buoyancy can be obtained. When a predetermined height is reached, the propeller 22 is directed forward for propulsion to fly horizontally. For landing, compressed air is supplied into the air bag 16 under pressure to reduce the buoyancy of the gas container 2 to land. In this case, the propeller 22 can be directed down for propulsion to increase the down going speed. The down propulsion, however, is stopped just before landing.

Title: Device and sensor for measuring refractive index
Inventor: IMAIZUMI TOYOAKI
IPC: G01N21/43
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a measuring device and sensor for refractive index capable of measuring the border between light and dark regions at a total reflection critical angel accurately with a high precision. SOLUTION: In this measuring method, the border of contrast on the basis of the total reflection conditions of a sample is determined through the use of a CCD to obtain the refractive index of a sample to be tested. Functions Rr (x) and Rm (x) indicating the characteristics of the amount of reflecting light with respect to the CCD pixel positions of a reference sample whose border between dark and light regions are known and the sample to be tested are each obtained, and the correlation coefficients of both the functions are obtained as either of the functions is being shifted toward a pixel position. The amount of a shift in which the correlation coefficient of both the functions becomes maximum indicates the amount of deviation between the borders between dark and light regions of the reference sample and sample to be tested.  After the maximum correlation coefficient is obtained by shifting in a large amount of a shift at first, the maximum correlation coefficient is obtained by shifting in a small amount. By this, it is possible to measure the border of contrast with high accuracy.

IPC: H03H9/02
Filed: 1988-11-30
Abstract: PURPOSE:To improve reliability by exciting a piezoelectric vibrator in liquid, and measuring the characteristic of the oscillator. CONSTITUTION:A crystal resonator 1 formed by sealing a crystal piece in a hermetically sealed vessel is housed in a liquid bath 7 as a constant temperature bath connected to a controller 3. The liquid bath stores the liquid with insulating property having a freezing point <=-90 deg.C and a boiling point >=150 deg.C. And it is connected to a measuring instrument 6 via an oscillation circuit 5 which excites the crystal resonator 1, and a temperature in the liquid bath is increased by, for example, 1 deg.C at every 15 minutes in a range of specification temperature from -30 deg.C to 60 deg.C, and the temperature characteristic of the crystal resonator 1 is measured. Therefore, since the crystal resonator 1 is soaked in the liquid, floating capacitance can be kept constant within the specification temperature. In such a way, it is possible to prevent the change of an oscillation frequency occurring due to the floating capacitance and to improve the reliability.

After a warning processing, the operating mode of a copying machine is confirmed. When the operating mode is not set, an operation is stopped. Then, the instruction of an operator is received in the case of a confirmation mode and the setting of a forced stoppage mode is judged when the confirmation mode is not set. When it is not set, a copying processing is ended and the next copying processing is started. Thus, at the time of the specification defect of the marker area in a processing mode, the inconvenient processing is prevented.

Title: Automatic water feeding device
Inventor: OKADA SADAO
IPC: E03C1/02
Filed: 1990-11-10
Abstract: PURPOSE:To eliminate a water hammer knock sound generated at a downstream side of a water-solenoid valve or vibration being transmitted to a bath tub by a method wherein the water solenoid valve is disposed at a hot water feeding pipe connected to a water supplying source, a pipe closing member branched and connected to the hot water supplying pipe at the downstream side of the water solenoid valve is disposed upwardly from a connection part with the hot water supplying pipe so as to form an air reservoir. CONSTITUTION:As a hot water feeding valve 17 is opened, hot water in a hot water feeding pipe 16 is flowed into a forward pipeline 31 of a bath circulation circuit 30a. At this time, the hot water is passed at the forward pipeline 31 from the pipe member 31a toward the pipe member 31b. However, air in the closed pipe member 51 branched and connected from the T-shaped pipe 52 is enclosed by the hot water passing therethrough to form an air reservoir 51A, and pressure of the hot water is absorbed by the air reservoir 51A. As a result, when the hot water feeding valve 17 is opened, the water hammering transmitted from the pipe member 31a is weakened and this striking action is eliminated when the hot water is directed toward the pipe member 31b.
