To provide a development system for lithographic printing plate precursors using a neutral developer, capable of preventing the non-image area of the resulting printing plates from being stained. In developing a lithographic printing plate precursor with a neutral developer having a pH of from 5.8 to 8.6, ultrasonic waves and/or an electric current are imparted to the neutral developer.

Method and apparatus for development of lithographic printing plate precursor

To provide a power supply apparatus that replaces a dry battery by detecting electric field energy in a free space, rectifying the energy, extracting the energy as electric power, and accumulating the electric power. In particular, there is provided a power supply apparatus that is useful for a portable electronic equipment. An electromagnetic energy conversion unit collects a radio wave propagating in the air and converts collected electromagnetic energy into electric power. A rectifying unit generates electric power having a DC waveform by rectifying electric power having an AC waveform and charges the rectified electric power having the DC waveform into a secondary battery. An electric load is supplied with the rectified electric power having the DC waveform or with electric power having a DC waveform discharged from the secondary battery.

Pulse wave detector

A pulse wave monitor having a structure capable of automatically performing optimal positioning of a pulse wave probe with respect to a user's body. A plurality of transmitting piezoelectric vibrators for transmitting an ultrasonic wave to an artery are provided along with a plurality of receiving piezoelectric vibrators for receiving an ultrasonic wave from the artery. An optimal combination of a transmitting piezoelectric vibrator and a receiving piezoelectric vibrator for use in pulse wave measurement is determined based on the intensity of a received ultrasonic wave signal. Ultrasonic wave transmission and reception are made by the optimal combination so that accurate pulse wave detection measurement is made possible by automatic positioning of the pulse wave probe.

The timing of a tide is calculated depending on a user-selected geographic region and calendar date. Tide data is stored in memory for each geographic region available for selection by the user. The timing of a tide is calculated by determining first and second tide level data using a tide level estimating equation. The first tide level data is dependent on the selected calendar date and the stored tide data that corresponds to the selected geographic region. The second tide level data having a time interval that is shorter in duration than a time interval of the first tide level is determined data again using the tide level estimating equation. The timing that a tide corresponding to the selected geographic region and calendar date occurs is then calculated dependent on the second tide level data. Thus, an accurate calculation of the timing of a desired tide is obtained for the user-selected geographic region and calendar date.

A tide meter for calculating a spring tide day. First, a moon age value is determined depending on a designated calendar. The moon age value includes at least one of the day of the new moon and the day of the full moon. Tidal data is stored that is specific for each geographic location, and this data is used in calculating the spring tide day for a selected geographic area. Since the time of the rising and falling of the tide depends on geographic location, simply calculating a spring tide day from the position of the moon and sun may not be accurate for a specific geographic location. Accordingly, the stored tidal data that corresponds to a selected geographic area is included in the spring tide day calculation. Thus, the accuracy of the spring tide day calculation is increased for the particular selected geographic area.

Measurement device, portable electronic instrument, and measurement

There is disclosed a portable GPS (Global Positioning System) receiver carried by a user. The receiver measures the distance traveled by the user and the speed. In the prior art technique, if satellites cannot be captured, no measurements are made. To find the distance and speed accurately, the measurements have to be performed continuously, thus increasing the electric power consumed by the receiver. The inventive receiver once finds the speed from the Doppler frequencies of the carrier waves. Then, a first distance-calculating means finds the distance from the speed. A walk-detecting means detects walking. A step number-calculating means accumulates the number of steps taken in steps. A stride-calculating means finds the stride from the accumulated step number and from the found distance. Then, a second distance-calculating means finds the distance from the stride and from the accumulated number of steps. A speed-calculating means finds the speed. The GPS receiver receives at regular intervals and updates the stride.

Portable GPS receiver

An improved GPS receiving apparatus may be worn on a user's arm and is not affected by the user's periodic arm swinging motion. A GPS signal receiver receives a GPS signal from GPS satellites, the receiver being mountable on a user's arm. A display is provided for displaying information based upon an output of the GPS signal receiver. An arm swing detecting circuit including an acceleration sensor detects the periodic swinging motion of the user's arm and outputs a corresponding periodic signal. A timing circuit sets a predetermined time during respective arm swing movements at which a GPS signal receiving operation will be performed based upon the periodic signal output by the arm swing detecting circuit. Operation timing of the GPS signal receiver is performed based on the output signal of the timing circuit so that a GPS signal receiving operation is performed at the same time during each cycle of periodic arm swinging motion to thereby cancel the effect of the periodic arm swinging motion.
