摘要:
To improve the characteristics of a portion which can be represented by an approximate first-order line (so-called linearity) in the relation between pressure and diaphragm displacement. To equalize the pressure-applying area/volume of a diaphragm when plural ring-shaped reinforcement ribs are in contact with said cover (no load condition when no pressure is applied to the diaphragm) and the pressure-applying area/volume of a diaphragm when said diaphragm is apart from said cover (the diaphragm is displaced due to pressure load).
摘要:
An aquascooter apparatus including a controller for preventing problems associated with water leakage into the aquascooter. The aquascooter has a battery, a driving motor and a clutch in a housing, and the controller includes a water leak detecting sensor that detects a leakage of water into the housing. A motor control is responsive to the signal from the water leak detecting sensor, and prevents the battery from supplying electric power to the driving motor responsive to this signal. This prevents electrical energy from being used if a water leak is detected, and therefore prevents any possibility of a dangerous situation of a spark in contact with hydrogen gas.

摘要:
A multi-point light measuring system for sensing an optical characteristic such as illuminance at a plurality of measurement points with respect to the same illumination is configured by a single main unit, a plurality of light measuring units and a plurality of adapters for data communication. At least one light measuring unit and the main unit are connected by wired or wireless adapters, and each adjoining two light measuring units is connected by wired adapters. A controller of the main unit controls the light measuring units by commands transmitted by the adapters for obtaining light measuring data from the light measuring units and displays a measurement result on a display of the main unit.
摘要:
A light measuring apparatus is provided with a photoelectric conversion element for converting a light energy to an electrical signal, a calculation circuit for calculating a measurement value based on the electrical signal, a memory for storing a correction value, a corrector for correcting the measurement value using the correction value, and a controller for allowing calculation of a recent correction value when the timer measures elapse of a predetermined time, and permitting the memory to renewably store the recent correction value.
摘要:
A light measuring apparatus capable of measuring ambient light, flash light from a flash source directly connected to the light measuring apparatus and flash light from a flash source that is remote. A photoelectric sensor can convert the light into electrical signals when an operator starts a light measurement cycle. A flash light emission signal can be generated to a flash source. The computer circuit can process the light signals to determine the specific mode of operation of the light measuring process, and based upon that particular mode of operation to appropriately calculate measurement values.
摘要:
With an exposure meter usable in both reflected light mode and incident light mode, the exposure meter is capable of displaying a value measured in reflected light mode with a reflected light mode attachment mounted on the exposure meter, and a value measured in incident light mode with an incident light mode attachment mounted thereon.
