Abstract: A mobile telephone terminal (1) includes a portable-unit (3) and an adaptor (2) which is capable of mounting the portable-unit on a vehicle and supplying power from a vehicle battery (7) to the portable-unit. The adapter includes a power switch (201) manually generating a switch signal and a delay circuit (23) which delays the switch signal by a predetermined period of time when the telephone terminal is in a communication state and the power switch is depressed in place of a call end key. In response to the delayed switch signal, a transistor switch circuit (24) stops power supply from the vehicle battery to the portable-unit. The portable-unit initiates a call clear process in response to the switch signal and during the predetermined period of time performs and completes the call clear process. In the call clear process, the portable-unit transmits a call clear signal to a base station over a radio channel used and turns off its radio frequency section. The call clear process makes the used radio channel available for other parties immediately after the call finishes.

Abstract: Treatment or prophylaxis of depressed or inadequate intracellular pyridoxal phosphate levels in a human or animal patient resulting from a condition, wherein the pyridoxine (PN) - pyridoxal phosphate (PLP) pathway is disturbed or insufficient, due to enzymatic insufficiencies inherent in the cells of a patient caused by genetic lack of oxidase or genetic oxidase polymorphism; cellular immaturity of premature infants; in conditions involving anemia, destruction of erythrocytes (e.g. malaria, biliary fever). The deficiencies are counteracted by the administration of pyridoxal or a precursor of pyridoxal which in vivo, once it has entered the bloodstream, is rapidly converted into pyridoxal without the intervention of oxidase or oxygen, optionally and preferably without the intervention of kinase.

Abstract: Accurate voltage measurements on fast changing waveforms are carried out via stroboscopic tunneling potention­metry using a tunneling microscope. The scanning tunneling microscope (STM) includes a test probe (22), having a test probe tip (23), and a sample (24) (with a conductor (25) supported thereon carrying the waveform to be sampled) arranged for measurement. The test probe (22) is supported so that the test probe tip (23) exhibits motion toward and away from the sample (24). The distance between the test probe tip (23) and the sample (24) modulates the tunneling current. In one embodiment, the test probe tip (23) is driven by a mechanical oscillator (100) to produce the desired motion. The mechanical oscillator (100) operates at a very high frequency (for example in the GHz ranges. The tunneling current flowing between the conductor (25) and the tip (23) which is a strong function of the instantaneous potential on the sample (24) is then determined by the convolution of the motion with the exponential dependence of current with respect to distance (between tip (23) and con­ductor (25)). Sampling is synchronized with the motion of the test probe tip (23). In other embodiments, the mechanical oscillator (100) is driven by a crystal oscillator (10) or replaced by an acoustic modulator in either tip (23) or sample (24) which has the effect of modulating the distance between tip (23) and sample (24) for the same purpose.

Abstract: The invention relates to an optical memory in which an optical recording medium (3) is built in a case (1), and also to a memory apparatus. Recording, reproducing and erasing operations are performed by irradiating light via a transparent portion of the case (1) onto the built-in optical recording medium (3). The optical recording medium (3) built in the case (1) has face vibrations with respect to the case (1), because it is moved within the case (1). The present invention is characterized by employing such a construction for optically mitigating irregular fluctuation in reflectivity caused by this face vibration. In the optical memory of the present invention, the reflectivity fluctuation caused by an interference effect made between reflection light from the case (1) and air, and also reflection light from the optical recording medium (3) and air due to the relative deviation in the face vibrations, may be reduced by antireflection films (2a, 2b) provided in the case (1) and the optical recording medium (3). In a memory apparatus of the present invention, the above-described memory is mounted, the fluctuation in the reflectivity is monitored and laser power is varied in order to further mitigate the reflection vibrations.

Abstract: The relay has a contact spring which is connected to the armature, is broadened in the T-shape in the region opposite to the armature end after a constriction and hence forms a double contact or a bridge contact. A supporting lug is in each case integrally formed on the two lateral limbs of the contact spring, which supporting lug engages with the armature end in the event of an armature movement directed to contact opening. In this way, the soft spring characteristic is maintained during closing of the contacts, while, during opening, the armature impact is exerted in the immediate vicinity of the contact pieces in order, if necessary, to separate welded adhesions and mechanical sticking. <IMAGE>

Abstract: Apparatus for digital amplitude regulation is disclosed, for use as a volume control or the like, utilizing pulse width modulation to control signal transmission through a two terminal non-linear element, the resistance of which varies with current, e.g., a diode (74) or diode like element. A stream of pulses (54), the duty cycle of which is variable and digitally controlled, is filtered (56,58) to produce a quasi-continuously variable reference signal (50). The value of the reference signal regulates gain by controlling the component of the signal (65) of interest that is actually available for amplification. For low cost implementation in a system already employing a microprocessor (52) or microcomputer the determinative duty cycle can be derived under software control and supplied as an output from a single latchable output pin (54). In an exemplary implementation, a derived DC component of the variable duty cycle pulses controls the DC output voltage from a voltage divider (62,64) and is used to regulate the magnitude of a series of fixed magnitude pulses (65). Additionally, the use of an energy storing type filter (56,58) allows the continuous stream of variable duty cycle pulses to be momentarily interrupted so that a pin used for supplying the pulses can be used for the performance of additional functions without affecting the perceived volume level.
