Title: Optical information reader
Inventor: MIZUTANI YUICHI
IPC: G06K7/10
Filed: 1999-10-20
Abstract: PROBLEM TO BE SOLVED: To provide an optical information reader which enables an operator to easily recognize the consumption of an internal battery without lowering the operation efficiency. SOLUTION: In a bar code handy terminal, a control circuit monitors the rest of a battery (S110). It is judged whether or not the battery rest is less than a specific value, i.e., whether or not the electromotive force of the battery drops almost to a voltage with which the operation of the handy terminal can not be guaranteed (S120) and when so (S120: YES), the current supplied to a guide light emission part is reduced (S130). Consequently, the illumination of the guide light projected on a recording surface decreases. A user feels the guide light projected on the recording surface darker to visually recognize that the battery rest becomes small and then replaces the main battery.

IPC: F23C99/00
Filed: 1994-12-01
Abstract: PURPOSE: To keep a burner compact and vaporization cylinder temperature proper and simultaneously prevent noise from being produced owing to secondary air. CONSTITUTION: The shape of a transparent hole provided in an outer periphery part of a vaporization cylinder fixing plate 5 is defined to be an elongated one having an enough opening area where no sound is produced even passage of air therethrough, and a plurality of elongated holes 10 are provided along an outer edge of a vaporization cylinder 1 on the side of a major axis thereof. With the construction, there is increased an area per one transparent hole in an outer edge of the vaporization cylinder fixing plate 5 so that a sound is prevented from being produced upon secondary air passing through the elongated hole 10. Further, since the elongated hole 10 is extended along the outer edge of the vaporization cylinder 7, there is eliminated the need of increasing the external configuration of the vaporization cylinder fixing plate 5 and hence a burner can be designed to be compact.  Furthermore, air passing through the elongated hole 10 cools the vaporization cylinder 7 to keep the temperature of the vaporization cylinder 7 proper.

Title: Article that includes optical waveguide
Inventor: STRASSER THOMAS A
IPC: G02B6/42
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To provide an article which includes an optical wavelength tap capable of preventing undesirable polarization effect from being received. SOLUTION: The dispersing optical waveguide tap includes a brazed chirped refractive index diffraction grating 14, a coupling means 15, and a utilizing means 19 in the core of a waveguide 12. In the presence of the coupling means 15, the diffraction grating 14 is so selected that guide mode light with specific wavelength is guided to >=1 clad mode of the waveguide 12. The presence of the coupling means 15 which optically operates with the waveguide 12 varies the guide state so that a clad mode is substantially removed from the part of the waveguide including a clad, and the diffraction grating 14 guides the guide mode light to >=1 emission mode. The utilizing means 19 includes, for example, an array of optical detectors and the coupling means 15 includes a glass member in a proper shape and a refractive index matching means.

Title: Photodetector and optical receiver
Inventor: ITO FUMIHIKO
IPC: G01J9/00
Filed: 1994-12-01
Abstract: PURPOSE: To detect interference fringes properly even when a spatial phase of the interference fringes changes at random by detecting a spatial fluctuation of a current distribution after a photoelectric current is detected resulting in observing an amplitude of an original optical signal. CONSTITUTION: After a photoelectric current is detected, a spatial fluctuation of current distribution is detected, resulting in observing an amplitude of an original optical signal. That is, in this detector, a difference of photoelectric currents outputted from 1st couple of light receiving elements 1-1, 1-3 is calculated by a subtractor 2 and a square of the difference of the photoelectric currents is calculated by a multiplier 31 and a difference of the currents outputted from 2nd couple of light receiving elements 1-2, 1-4 is calculated by the subtractor 2 and a square of the difference of the currents is calculated by the multiplier 31 and the output signals from both the multipliers 31, 31 are added.  The two light receiving elements in pairs are arranged at positions parts by 1/4 period of the interference fringes to detect the interference fringes by either of the light receiving elements even when the phase of the interference fringes changes in any way.

Title: Gravure offset printing press
Inventor: USUI TOSHIO
IPC: B41F17/10
Filed: 1993-11-29
Abstract: PURPOSE:To carry out the printing in which the content is varied precisely and securely on a continuous material. CONSTITUTION:The driving force of a driving motor 4 is transmitted to a first clutch brake 5 and a second clutch brake 6. A first gear 33 and a second gear 36 are rotated by the rotation of the first clutch brake 5, and a B gravure roll 30 is rotated through a roll shaft 32. As the number of the gears of the second gear 36 is formed more than that of the first gear 33, the first gear is rotated more than one time while the second gear 36 is rotated one time. The B gravure roll 30, therefore, is rotated faster than an offset roll 20 of the same radius, and the position where a protruding section 22 is brought into contact with the B gravure roll 30 is deviated every time of rotation. Thus the printing in which the content is varied can be carried out precisely and securely.

Title: Information recording medium
Inventor: IWASAKI HIROKO
IPC: G11B7/2433
Filed: 1990-11-06
Abstract: PURPOSE:To make it possible to repeat recording-deletion with a low power and stably by providing a specific relationship between an average particle diameter in a stable phase of a phase dealing with transition of recording state and an average particle diameter in a stable phase of a phase which does not make the transition. CONSTITUTION:A record material in an information record medium includes at least 2 kinds of phases. Assuming that a composition average volume ratio Va/Vb of a volume Va of a phase A dealing with transition of state at recording and a volume Vb of a phase B which does not make the transition is gammao, there is a relationship between gammao and an average particle diameter Ra in a stable phase of the phase A and an average particle diameter Rb in a stable phase of the phase B satisfying a formula (I). The average particle diameter represents an average size of a grain to be obtained by line breadth in X-ray analysis and TEM observation means. By keeping mainly the size of the particle diameter of the phase dealing with the phase change constant, stress exerted on the record material by heat history is confined to the minimum, so that repeating property and life can be improved widely. Also, melting point is cured by atomization so that recording and deletion can be performed with a low power.

Abstract: PROBLEM TO BE SOLVED: To quickly respond to different temperature pure water supply requested from a load side and the change of the supply quantity, by correctly selecting heated pure water or normal temperature pure water, based on the request from the load side so as to supply to the load, and continuing the heating operation for the heated pure water even when the heated pure water supply is stopped. SOLUTION: First and second electropneumatic adjusters 3 and 8 which received a PID control signal respectively adjust the opening of first and second pneumatic control valves 4 and 9 based on the control signal, control the respective flows of heated pure water and normal temperature pure water, and supply the mixed pure water at a prescribed temperature to a prescribed flow load 13 through a mixed pure water supply line 2. In the case where a request from the load side is only for the normal temperature pure water or the case where the request is to temporarily stop the heated pure water supply, an autovalve 5 is opened, a small quantity of the heated pure water is ejected and the operation of a heating means of a heated pure water supply source is prevented from stopping so as to meet the re-request for the heated pure water from the load 13.  Thus, it is made possible to quickly adjust the pure water temperature and to quickly respond to the supply quantity change.
