Title: Magnification controller for optical system scanning mechanism
Inventor: KOIDE HIROSHI
IPC: G03G15/041
Filed: 1980-03-04
Abstract: PURPOSE:To reduce a mechanical moving part and to enable to speed up an optical system scanning mechanism, by providing the 1st pulse generating means producing a pulse signal relating to the 1st drive section which is standardized. CONSTITUTION:The 1st drive section 20 is directly or indirectly fitted with the 1st pulse generating means 22 consisting of encoders, and pulse signals are sequentially generated in relation with the operation of the 1st drive section 20. The signal output from the 1st pulse generating means 22 (frequency in fb) is wave-shaped at the amplifier (including wave shape circuit) 23 and then input to the 1st phase loked loop PLL-1. Thus, for example, the method controlling the revolution of a motor and stopping it at the home position are used. Thus, since only few mechanical moving parts are required for this magnification controller, the high speed optical system scanning mechanism is realized.

Title: High-speed optoelectronic element module
Inventor: YOSHINO KAORU
IPC: H01L23/28
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To improve the temperature stability of an optoelectronic element against the fluctuation of the ambient temperature by using a high-frequency wiring board composed of an insulator having a lower coefficient of thermal conductivity than alumina has and high-frequency lines in at least part of the connecting circuit between the element and an electric signal terminal. SOLUTION: In order to obtain heat insulation between a package 7 and an optoelectronic element 1, mullite is used for forming a microstrip high-frequency wiring board 2A. Mullite has a high frequency loss as alumina does, but has a very low coefficient of thermal conductivity as compared with alumina. When the width of the substrate 2A, length of a heat insulating section, and the thickness of electrode gold are respectively 1mm, 1mm, and 1.5μm and the temperature difference between the package 7 and element 1 is 50 deg.C, the heat conducting quantities of a mullite board and an alumina board respectively become 43mW and 330mW.  Therefore, the Peltier current which is required for obtaining a temperature difference of about 50 deg.C can be reduced by 10% when the mullite board is used and the temperature stability of the element 1 against the fluctuation of the ambient temperature can be improved.

Title: Color picture processing method
Inventor: USAMI AKIHIRO
IPC: G06T1/00
Filed: 1992-02-13
Abstract: PURPOSE:To precisely calibrate a reader and a recorder. CONSTITUTION:The picture reader 4 reads a color original with several tens of colors which are previously known. A 3X3 matrix operation part 1 processes read RGB signals and makes them into C-RGB signals. A coefficient in the 3X3 matrix operation part 1 is obtained in such a way that a C-RGB signal value obtained by calculation nearly coincides with a signal value after matrix operation in the 3X3 matrix operation part 1 from the original 3 for which the colors are previously known. The previously decided C-RGB signal is inputted to a picture recorder 5 and a hard copy is outputted from the picture recorder 5. The colors are measured and the colors corresponding to the colors are obtained by calculation based on the previously decided C-RGB signal. CPU 7 decides the parameter of a LOG transformation/masking processing part 2 so that deviation between a measured value and a calculated value in reduced.

Title: Navigator mounted on vehicle
Inventor: IKEDA TAKEO
IPC: G01C21/00
Filed: 1990-02-05
Abstract: PURPOSE:To shorten a route calculation time by allowing the 1st route calculating means to retrieve a connection node between upper and lower hierarchical layers from a road net data including a current position and allowing the 2nd route calculating means to retrieve a connection node between upper and lower hierarchical layers including a destination to calculate respective routes. CONSTITUTION:The route is calculated by a 1st route calculating means D1 to guide a driver from the current position up to a node included in the prescribed range W2 of the destination and then the detailed route up to the destination is calculated by a 2nd route calculating means D2 to guide the driver up to the destination. Since the calculation of detained routes around an extremely far destination e.g. can be postponed, the whole calculation time can be shortened as compared with a case for calculating detailed routes around the destination from the initial stage, and when conditions on the way of traveling are changed, it is unnecessary to recalculate the route.

IPC: G03B7/00
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To enable not only an operation value set every specified turning angle of a rotary type operation member but also the intermediate value thereof to be set by combining the rotary type operation member and a reciprocating moving type operation member. SOLUTION: When a rotary dial 10 is rotated so as to change shutter speed after the intermediate value is set, a canceling lever 17 is moved in a direction that it is separated from the dial 10 because the tip small-diameter part thereof is pressed by the projecting part 16a of a cam plate 16. By the movement of the lever 17, an interlocking projection 24 is pressed by a return tapered surface so that a slider 20 is returned to a neutral position. When the dial 10 is turned to the position of a next shutter speed value, the tip small-diameter part is engaged with a recessed part 16b and returned except the position of the projection 24. On this condition, the set and the release of the intermediate value can be freely executed again by the slider 20. Besides, the finer operation value can be set.

A structure to be treated comprising at least two elements which are different in the degree of corrosion by the treating medium is produced, and at least a part of at least one element in the structure is removed selectively by the treating medium. In this way, when the catalyst is supported, the contact area per catalyst volume between the catalyst and exhaust gas can be increased.

Title: Power supply
Inventor: OMORI TETSUO
IPC: G05F1/10
Filed: 1992-02-14
Abstract: PURPOSE:To realize substantial increase of power interruption sustaining time by detecting input voltage drop and performing back up with an auxiliary voltage taken out from main output side thereby varying the power interruption sustaining time depending on load power. CONSTITUTION:In the power supply, an AC power supply 1 is rectified through a rectifying circuit 2 and filtered through a capacitor 3 to produce a DC voltage. Upon interruption of AC input voltage under low load current, a rectified voltage and a voltage multiplied through a transformer drop uniformly with a reduction coefficient corresponding to the load current. The voltages drop slowly because of the low load current, but the capacitor voltage drops constantly because current consumption of an auxiliary power supply circuit is scarcely influenced by the magnitude of the load current. When energy is fed to the auxiliary voltage by connecting a diode, auxiliary voltage drop can be positioned at a value equal to the output voltage minus forward voltage drop of diode and a control circuit is prevented from entering into nonoperative state resulting in prolongment of power interruption sustaining time.
