Inventor: AMAMOTO NARUSHI
IPC: G01R23/173
Filed: 1991-09-27
Abstract: A measuring unit (10) converts a measuring signal into an intermediate frequency band of a predetermined bandwidth and detects the intermediate frequency band while a reception frequency is set variable by variably controlling a local oscillation frequency of a local oscillator (12). A waveform memory (21) stores the magnitude of a detection signal output from the measuring unit in correspondence with the frequency. An analyzing unit analyzes a frequency component included in a signal to be measured, on the basis of a storage value of the waveform memory. An analysis target frequency data (32) setting unit sets frequency data of a desired analysis target frequency or interval frequency data thereof. A sweep control unit (33) changes the reception frequency of the measuring unit into the desired analysis target frequency corresponding to the frequency data set by the analysis target frequency data setting unit and outputs an address signal corresponding to the received analysis target frequency to the waveform memory every time a signal synchronized with an ON/OFF change of the signal to be measured is received.

Abstract: Preparation of a thin layer (5) of crystalline oxide such as a garnet, a spinel ferrite, a hexaferrite, a perovskite, an acousto-optical oxide, a phase transition oxide or a superconductive oxide employing an annealing by irradiation by means of a lamp (1) although the oxide to be crystallised may be transparent to the radiation of the lamp. First of all a thin amorphous layer is prepared, of an oxide which is substoichiometric in oxygen of the same elements as the oxide to be crystallised, to obtain an opaque layer absorbing the radiation. This layer of substoichiometric oxide is then subjected to annealing under irradiation in order to crystallise it and the stoichiometry in respect of oxygen of the crystallised layer is restored to make it transparent. The thin layers prepared in this way can be employed in particular in reenterable thermo-magneto-optical discs on substrates which do not withstand the crystallisation temperature of this layer, for example substrates made of organic material. <IMAGE>

Abstract: A diaphragm 70 and method of manufacture for use in a pressure regulator, or other similar uses, where leakage around the confined edges of the diaphragm must be avoided. The structure confining the edges of the diaphragm consists of a main housing body (20) having a groove (32) for receiving a rib (72) on the outer periphery of the diaphragm and a secondary housing (50) to clamp the periphery. The central portion of the diaphragm carries a top plate (75) with a bottom groove (83) to receive a rib (74) on the central periphery of the diaphragm and a bottom disc (90) to clamp the inner periphery. Diaphragms are made with a fabric (200) sandwiched between flexible layers (200A,200B) of material. This results in a flash edge (202,204) which may cause wicking and prevent a proper seal in the grooves receiving the ribs. An angled trim on the peripheries allows a proper filling of the grooves and a leak proof seal.

Abstract: A device for measuring a movement between two parts (23, 27) is proposed which provides for high resolution of the movement. A first and second radiation (13, 14) are divided into a first measurement radiation (18, 18a) and into a second measurement radiation (19, 19a) which in each case extend in two optical systems (17, 20). The two measurement radiations (18, 19, 18a, 19a) in the two optical systems (17, 20) are directed towards a reference grating (22) which is allocated to a first part (23). The reference grating (22; 22a, 22b) in each case distracts the two measurement radiations (18, 19; 18a, 19a) in such a manner that common loci of impingement (25 26) are produced which are located on a measuring grating (24) which is allocated to the second part (27). The measuring grating (24) again distracts the two measuring radiations (18, 19; 18a, 19a) in each case in the same direction in which an interference takes place. The radiations (29, 30) which have interfered with one another are detected by radiation sensors (31, 32). <IMAGE>

Abstract: The invention relates to the mixing of individual fibre components on the basis of properties of a required intermediate product, for example a card sliver, or of a required end product, for example a yarn. This mixing takes place in that fibre bales (2) are combined to form component groups, and the fibre components of these groups are administered accurately by means of metering devices (11) to a mixer, in which these components are mixed homogeneously. The product of the mixer is subsequently cleaned in a cleaner (60) and is thereafter transferred for processing to a card (63). After the card, the card sliver is tested in a colour tester (65), and the corresponding signal is transmitted to a control (7;7.1;7.2;44) which primarily controls the component mixture and secondarily is corrected by such a colour signal, insofar as the primary mixture control is varied correspondingly, until the colour at the exit of the card is correct again in the card sliver. Furthermore, the card sliver is tested for fibre fineness (MICRONAIR) by means of the fibre-fineness tester (66), and a corresponding signal is transmitted to the abovementioned control. The abovementioned component mixture is likewise changed on the basis of this signal, if the fineness differs from a predetermined desired value. A third signal (81) comes from the card control (64). This signal transmits the output (kg/h) to the abovementioned control, in order to control the stripping capacity of the stripping devices (20,23). <IMAGE>

Abstract: A synchronization controller identifies the timing of the group assigned to the receiver based on a synchronization signal detected by a preamble and synchronization signal detector. At this timing the power supply of a radio section is turned on. A selective calling number within the received group and pre-assigned selective calling number are compared in a selective calling number detector. The power supply of the radio section is immediately turned off, if the result of the comparison is non-coincidence. In this way, the battery saving efficiency can be enhanced by arranging to turn on the radio section only in the groups which are assigned to the receiver, and turning off immediately the power supply of the radio section when the receivers assigned selective calling number is not found in the receiver's assigned group.
