Title: Radiant ray picture information reader
Inventor: ONO SHUJI
IPC: H04N1/14
Filed: 1988-02-09
Abstract: PURPOSE:To surely and easily attain preliminary read and major reading by applying the scanning of an accumulative type fluorescent sheet in the advance read part at a position deviated from the converging position of the excited light due to scanning lens prior to the accumulative fluorescent sheet in the major read. CONSTITUTION:When a rotary polygon area 8 is rotated, a laser beam 22 is deflected by a prescribed angle, part of the laser beam 32 is transmitted through the half mirror 38 and an advance read laser beam 48 whose strength is reduced is obtained. Since the advance read laser beam 48 is deviated from a focus, the beam diameter is expanded. Thus, the main scanning line 58 is an expanded main scanning line. The control circuit decides the amplification factor setting value at the major reading, the read condition such as recorded scale factor setting value and picture processing condition setting value based on the inputted radiant ray picture information. Thus, an expensive optical system component is used in common to the optical system constitution component for the advance read and the major read, and the advance read and main read are applied separately.

Title: Motor-driven camera
Inventor: KAWAMURA MASAHARU
IPC: G03B17/00
Filed: 1988-02-08
Abstract: PURPOSE:To make appropriate the quantity by which film is slightly rewound at the end of preliminary rewinding by detecting the generating frequency of 1st signals arising when one frame is fed and stopping the drive of a film rewinding mechanism in response to the occurrence of 2nd signals indicating the feed of a first frame when said frequency exceeds a prescribed value. CONSTITUTION:Upon the completion of preliminary rewinding, the film is previously rewound by a certain amount in order to associate the exposure frame of the film with the rotating position of a follower sprocket in terms of phase. To rewind the film by an appropriate amount, a distance from the initially rewound film to a brush 85 going to a duty control section as one frame phase is judged from the number of comb line patterns 94a (the number of pulse signals) which actually engage with the brush 85. When the number is less than the prescribed number, the film is rewound by one frame, whereas when the number exceeds the prescribed one, the rewinding amount is judged to be appropriate, and a motor is stopped at that point. Thus, the rewinding amount at the end of preliminary rewinding can be set appropriately.

If the selective printing mode is set by a selective printing detection device, a printing head 33 is positioned at a detection position on the sheet 32 which is stored in the storage device 38 using the printing head transport mechanism. After that, characters stored in the storage device 38 are printed by the printing head 33. Subsequently specified characters are automatically printed at the same place as a place where a color is applied on the sheet 32.

Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To facilitate the identification of the primary components responsible for thermal efficiency deterioration by calculating the heat balance regarding each component of the thermal power plant, performing convergence calculations of the measurement data wherein the measurement data and heat balance are taken as the standard value and are recognized to be low precision, and determining the heat balance of the overall plant. SOLUTION: Measurement data which is detected from a plurality of sensors 21a through 21n which perform measurements with regard to thermal efficiency is incorporated into a computer system 22. Then, internal heat balance calculations of high, mid, and low pressure turbines, and heat balance calculations of each heater and around each deaerator are performed based on highly precise data with almost no measurement error such as that of the input/output heat from each turbine, input/output heat from each heater and around each deaerator, and the output of each power generator and the like. Those measurement results are then taken as the standard value and convergence calculations of the measurement data with expected calculation errors such as that of main steam flow rate and the turbine extraction steam flow rate are performed. The overall heat balance is then determined.  Based on this and the degree to which component performance contributes to thermal efficiency, the primary components responsible for thermal efficiency deterioration are identified.
