Title: Data carrier
Inventor: SATCHELL DAVID H
IPC: G01N35/02
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To reduce the necessity for orientating a container before reading or detecting a data carrier by providing a data-supporting part that is seen from nearly all directions at the detector of data carriers. SOLUTION: A data carrier has a data-supporting part that can be seen from nearly all directions at a detector. More specifically, a container supports a label 133A for easily identifying a container and indicating information such as calibration data and control data. The label 133A has a data carrier 135A such as a high-density data carrier, which contains information for facilitating the execution of decision. This sort of data carrier 135A can take various kinds of forms such as a bar code and a memory chip. The data-supporting part of the data carrier 135A can eliminate the need for specific orientation with a detector since it is seen in nearly all directions for the detector such as a bar code reader.

Title: Formation of lb film
Inventor: TANABE YUKA
IPC: B05D1/20
Filed: 1990-09-26
Abstract: PURPOSE:To form the LB film having desired intra-surface molecular orientation by arraying plural pieces of substrates vertical in one row and executing accumulation while controlling the widths of the respective substrates and inter-substrate specings by using a Langmuir-Blodgett method, and controlling the orientation rate of film forming molecules on the relative positions of the respective substrates mentioned above. CONSTITUTION:The plural substrates 1 are disposed vertically in one row and the dependency of the dichromatic ratio R on the relative positions in the transverse directions of the substrates is controlled by changing the ratio l/a of the width of the substrate (a) and the inter-substrate spacing (l). The molecules are oriented well in the accumulation direction at the center of the substrates 1 when l/a=1(l/a). The orientation is the poorer, the nearer the end of the substrates 1. The orientation at the center of the substrates is poorer with an increase in l/a and the orientation at the end of the substrates 1 improves correspondingly. The LB film having the desired intra-surface orientation is produced if the l/a is changed in such a manner. Visible polarized light absorbing spectra, IR absorbing spectra, Raman scattering spectral, electron resonance spin spectral, etc., are usable as the means for evaluating the orientation of the LB film.

Title: Image forming device
Inventor: KUWABARA SATORU
IPC: G03B27/32
Filed: 1989-09-29
Abstract: PURPOSE:To always obtain a stable picture even when a discharge tube is used as an exposure lamp by allowing the rate of plural filters occupied in the optical path of light reflected from an original or light transmitted through the original based on a tone correction value corresponding to the temperature of the exposure lamp to be changed and keeping the tone of the reflected light or transmitted light constant. CONSTITUTION:A temperature measuring means B measures the temperature of the discharging tube A; a control means C reads the tone correction value corresponding to the temperature, from a storage means D. The control means C controls a driving means E based on the read tone correction value; the driving means E drives plural filters F. The plural filters F allow the rate of occupancy to the optical path of the reflection light generated by reflecting the light emitted from the discharging tube to the original or the transmitted light generated by transmitting the original to be changed. Thus, even when the discharge tube is used as the exposure lamp, a stable picture is always obtained.

Abstract: PURPOSE:To improve the responsiveness when a valve is opened and to increase the speed of valve opening operation by providing the third pressure chamber for assisting valve opening operation in the interior of a small diameter portion of a valve member having a large-diameter portion and a small-diameter portion. CONSTITUTION:A valve member 22 has a large diameter portion 23 and a small diameter portion 24, and a taper surface 25 is formed between both portions. The third pressure chamber 32 is formed in the interior of the small- diameter portion 24, opened to the end portion 24a and communicated with the second pressure chamber 30 through a through hole 33. When an electric current is applied to a solenoid 40, the valve member 22 is moved upward, so that the taper surface 25 seats on a valve seat 28 to close the valve. Though at that time, downward differential pressure force is produced in the valve member 22, the valve is not opened. When the power is cut, the valve member 22 is pushed down by differential pressure force and the urging force of a spring 42, the pressure in the third pressure chamber 32 is increased because the passage between an armature 44 and the second body end surface 36a is throttle, so that the valve opening operation of the valve member 22 is promoted to improve the valve opening responsiveness.

Title: Gas meter
Inventor: KIMURA YUKIO
IPC: G01F1/00
Filed: 1990-09-26
Abstract: PURPOSE:To improve accuracy and reliability of a gas meter and restrain pressure loss of gas small by providing a porous member in a gas introducing passage. CONSTITUTION:A mesh member 62 having some meshes as a porous member is fitted on the opening end of the remaining chamber 10 side of a gas introducing passage 60. The mesh member 62 has the function to regulate gas flow passing through it. When the mesh member 62 is directly fitted to a nozzle part 22 of small sectional area of passage, pressure loss of gas becomes large, ejecting force to a flow sensor part 20 becomes insufficient, and hardly generates vibration of gas flow in the flow sensor part 20. Hereby, the mesh member 62 is fitted in the gas introducing passage 60 having larger sectional area of passage than the nozzle part 22. By passing gas from a remaining chamber 10 through the mesh member 62 and the gas introducing passage 60, gas is regulated with both the mesh member 62 and the gas introducing passage 60, vibration of gas flow in the flow sensor part 20 is stabilized, the frequency is favorably in proportion to gas flow, and measuring accuracy is improved.

SOLUTION: Under an initially set condition (a), namely, when a rotating angle of a sample 2 is α and an angle of incidence of primary X-rays 5 is θ, monochromatic primary X-rays 5 are projected to the sample 2. Intensities of fluorescent X-rays 7 of a specific wavelength and secondary X-rays (scattering X-rays) 8 of the same wavelength as that of the primary X-rays 5 and scattering at a sample surface 2a are measured by a detector 4. Thereafter, a base 10 is rotated about a Z axis thereby to change only the rotating angle α of the sample 2 which is a condition (b). Under the condition (b), intensities of the fluorescent X-rays 7 and scattering X-rays 8 are measured in the same manner.  A calculating means 14 removes influences of fluorescent X-rays 9 generated in the detector 4 on the basis of the intensities of the fluorescent X-rays 7 and scattering X-rays 8 measured under the two conditions (a), (b), and correctly calculates the intensity of the fluorescent X-rays of the specific wavelength generated from the sample 2.
