Abstract: A belt-shaped member supplying method and apparatus are used for cutting a long material (1) paid out of a winding roll into a belt-shaped member (s) of a predetermined length and supplying the belt-shaped member onto a winding drum (10) by means of a transfer device (9). The method includes steps of modifying an extending direction of a front edge of a long material, whose initial front end portion has been cut off, into a desired direction by applying an external force upon a front end portion of the long material, holding the front end portion of the long material, paying out the long material of a predetermined length, cutting the paid long material to form a belt-shaped member, modifying an extending direction of a rear edge of the belt-shaped member into a desired direction by applying an external force upon a rear end portion of the belt-shaped member, holding the rear end portion of the belt-shaped member, transferring the entire belt-shaped member to a predetermined position, taking up any slack of the belt-shaped member, holding the belt-shaped member against a plate-shaped transfer device (9), and moving the plate-shaped transfer device together with the belt-shaped member to the winding drum.

Abstract: An integrated circuit is made by a technique that provides a planar dielectric over gate, source, and drain regions without over-etching of the gate contact region. In the inventive process, the contact windows (303, 304, 302) are etched in the conformal dielectric (201) prior to the planarization step, so that the etch thickness is the same for the gate as for the source/drain windows. Then, a sacrificial planarizing polymer (e.g., a photoresist) (401) is deposited to cover the conformal dielectric and fill the etched windows. Finally, a planarizing etch-back is performed, and the polymer is removed from the contact windows. A planarized dielectric is achieved without excessive etching of the gate windows (302).

Abstract: In order to effectively demodulate an incoming RF signal which takes the form of bursts in a satellite communications system using a Single Channel Per Carrier Demand Assigned Multiple Access (SCPC-DAMA) technique, a controller (40) is provided which is operatively coupled to a down-converter (10) and a demodulating section (12'). In the event that the RF signal is a continuous signal, the controller routes an AGC signal (51), which is outputted from the demodulating section, to a first variable attenuator (14) provided in the down-converter and applies a constant potential (44v) to a second variable attenuator (24') within the demodulating section. On the other hand, in the event that the RF signal assumes the burst format, the controller retains a value of the AGC signal at the time when the RF signal undegoes the continuous-burst change and applies the retained value of the AGC signal to the first variable attenuator. The controller further allows the AGC signal to be applied to the second variable attenuator while the RF signal takes the form of the bursts.

Abstract: A device for ionizing a sample includes a space 8a separated from the environment, and the sample is injected and nebulized into the space 8a. Fluid introduction pathways 9a are formed adjacent to a position where the sample is injected, so as to introduce fluid into the space 8a. The introduced fluid is brought into contact with a flow of the injected sample, thereby promoting production of a mist of the sample having finer particles. Then, the pressure of the space 8a is reduced, and the space 8a is shaped to maintain its pressure-reduced condition. Since the space 8a to which the sample is injected is separated from the environment, the fluid delivered to the flow of the injected sample is hardly influenced by turbulence of the environment, to thereby effect constant production of a fine mist and accordingly reliable ionization of the sample. An apparatus 14 for mass spectrometry of the sample is constituted by combining this ionization device with a liquid chromatograph 1 to 5 and other required system elements.

Abstract: 2.1 Chucks for glass tubes must be constructed in such a way that, on the one hand, they grasp the glass tube gently in order to ensure that it is not destroyed and, on the other hand, hold it firmly enough to ensure that the glass tube can be worked safely. This requires a technical complexity which increases the dimensions of the chuck, and leads to a narrow diameter range of glass tubes which can be clamped. For a different diameter range, the chucks must be modified. The new chuck is intended to have a wide diameter range while having small external dimensions. 
<??>2.2 The chuck (1) has clamping jaws (18) which are displaceable radially relative to its longitudinal axis (LA) and the distance of which from the longitudinal axis is determined via a pressure sleeve (8) which is connected via a positive guide (16, 17) to the clamping jaws. The positive guide forms an angle of 30 DEG  to 60 DEG , preferably 45 DEG , to the longitudinal axis. 2.3 The chuck serves to hold a glass tube in a bottle making machine.

Abstract: filtering system for separating two signals included in different frequency bands, in which the composite signal S1 + S2 to be separated is input into an inductive element (LH) belonging to the high frequency filter section, in which element therefore the high frequency signal S1 and also the low frequency signal pass; said signal S1 is immediately coupled by means of mutual induction with a resonant element of said first filter section, said resonant element being made-up so that the low frequency signal S2 cannot be coupled with itself becouse of the low value of its frequency; then said sole signal S2 is transmitted towards the low pass filter section acting as rejection section of the high frequency band, which therefore has been introduced into the resonator and separated without passing or interesting the low frequency filter section and without suffering the deterioration caused by its passage into said low frequency filter section.

Abstract: The measurement of an angle of incidence ( alpha ) of a light beam (W) uses a polarised light beam which is passed through a birefringent plate (7) and then through an analysing polariser (9) to obtain a series of interference fringes. The spacing between the peaks of the said fringes, which is a direct function of the angle to be measured, is analysed using a suitable detector (10) and an electronic circuit (11). 
<??>A device of this sort can be used to measure the distance between itself and a reflecting surface on the object to be measured (12). A reference spacing between the peaks of the interference fringes is determined for a certain position of the object and the variation in the spacing is measured as a function of the various positions of the object. These positions are then displayed in units of length. 
<??>With such a method, angles of incidence or distances can be measured using a device which is compact, has a greater range of measurement than previously and is more accurate.

A wide detection bandwidth is also obtained by providing a semiconductor optical amplifier (10) having two current injection electrodes. A bias current (20) is supplied through both current injection electrodes, and both electrodes produce optical gain. However, only one of the electrodes is used for optical signal detection.
