A selective calling receiver includes a selective calling receiver main body, a chain clip, a detection circuit, and a control circuit. The selective calling receiver main body has a notification unit for performing a notifying operation when a numerical signal is received The chain clip includes a conductive metal chain and has one end connected to the selective calling receiver main body and the other end connected to a clip. The detection circuit is arranged in the selective calling receiver main body and is electrically connected to the chain clip to detect that a user touches a portion of the chain clip. The control circuit is arranged in the selective calling receiver main body and stops the notifying operation of the notification unit when an output is generated by the detection circuit in a notification enable state.

摘要:
A surface defect detector for detecting a gentle wavy defect and a minute rough defect on a surface of an object. The detector has a conveyer to move the object in a linear direction, a laser beam generator to irradiate a laser beam onto the object in a direction perpendicular to the linear direction, two photoreceptors to generate two different signals in accordance with a reflection of the laser beam from the object, a separator to optically separate the photoreceptors, and a processor to process the signals from the photoreceptors to detect the gentle wavy defect and the minute rough defect.

A mechanism for feeding a radiation image storage panel from a cassette to a read-out means is provided which comprises a cassette for keeping therein the image storage panel which has a panel release part; a tray which receives thereon plural panels in such manner that the panel release part of each cassette is positioned downward; a cassette lock release means having a means to give an action to the cassette to open the panel release part so that the panel in the cassette is dropped down; a moving means for moving the tray or cassette lock release means, and a guide member for receiving the dropped panel and guiding the panel to the read-out means.
摘要:
This invention relates to a process for preparing 2-chloropropionaldehyde (2-CPA) by using vinyl chloride, carbon monoxide and hydrogen as raw materials. Although processes making use of cobalt catalysts have conventionally been known, it is disclosed herein that by using a rhodium compound and a nitrogen- or phosphorus-containing Lewis base in combination as a catalyst, the reaction is allowed to proceed at temperature and pressure lower than those required for such conventional processes and the selectively toward the intended product is improved. It is also disclosed that by causing water to exist in the reaction system and using a water-insoluble organic solvent, fractionating the reaction mixture into a water layer and an organic layer after the reaction and then collecting 2-CPA from the water layer through distillation, extraction or the like, the rhodium compound contained substantially in its entirety in an organic layer can be reutilized in the form of its solution. This process is an extremely good process suitable for use in the preparation of 2-CPA which is useful as an intermediate for chemical products, agricultural chemicals, pharmaceutical products, etc.

A wireless transmitting and receiving system includes an ear microphone of the vibration pick-up type for picking up bone-conducted voice signals through an external auditory ear canal wall of a wearer. A portable case is disposed adjacent the wearer's ear and a wireless device is attached adjacent the wearer but spaced from the portable case. A transmitter of a transmitting circuit for transmitting the output signals of the ear microphone is housed in the portable case. A receiver of a receiving circuit is housed in the wireless device and receives signals from outside the system. The transmitting and receiving circuits provide a wireless connection between the portable case and the wireless device permitting two-way communication through one ear of the wearer.
摘要:
A process for the separation of oil from waste water containing the same in the form of fine particles, comprising introducing a hydroxide or oxide of calcium or a mixture thereof into the waste water for adsorbing the oil on the hydroxide or oxide and/or coagulating the oil, adding an acid or an alkali to the waste water for dissolving the oil-adsorbing hydroxide or oxide to liberate the oil, and separating the liberated oil from the waste water.
