Title: Transmission circuit with improved gain control loop
Inventor: ENOKI TAKASHI
IPC: H03G3/30
Filed: 1994-11-15
Granted: 2000-02-15
Abstract: In the transmission circuit, part of the output signal of the transmission circuit is derived by an output monitor circuit, and, after being subjected to envelope detection by an output detector circuit, the output signal of the output detector circuit is inputted to a peak hold circuit successively holding the peaks of the input signal, so that varying amplitude components are removed, and a DC value is detected. An error detector circuit compares the detected value with a reference signal generated from a reference signal generator circuit, and the error signal is used as a gain control signal to control the gain of a power amplifier circuit.

Abstract: A system and method for editing program material provide viewers with real-time editing control. Digital program material are divided into relatively short segments and each of these segments are rated to indicate a level of potentially objectionable material contained therein. Each segment is tagged to indicate this rating. Prior to viewing the program material, or during playback of the program material, the viewer determines the rating level at which he or she wishes to view the programmaterial. This rating level is entered into the playback system. Upon playback, the system examines the tag of each segment to determine whether that segment shouldbe played. If a segment is tagged to indicate a rating with a higher level than that requested by the viewer, the tag is edited and not displayed. Thus, the program material is edited in real time as it is displayed to the viewer.

Title: Method and apparatus for producing a primary roll of material, or for determining an amount of material available on a primary roll
Inventor: LAPLANTE BENOIT
IPC: B65H26/08
Filed: 1994-05-26
Granted: 1996-11-12
Abstract: The method is provided for producing a first primary roll (8) having a predetermined lateral surface defined by a diameter Df, or for determining an amount of material available on a primary roll. The primary roll is made of material wound around a spindle (6). The material is used to produce smaller secondary rolls (12) of material. The method for producing the primary roll of material comprises steps of (a) calculating portion Sf of the lateral surface, which is covered by the spindle; (b) calculating a portion Si of the lateral surface, which represents material needed to produce the smaller secondary rolls of material; (c) calculating a compression factor K1 which is derived from a compression rate K of a previous second primary roll used to produce previous secondary rolls with respect to the previous secondary rolls; (d) calculating Df where: Df = <IMG>; (e) winding up material around the spindle to produce the first primary roll until a diameter of the first primary roll reaches said diameter Df; whereby loss of material is reduced by taking into account compression factor K1 which varies with respect to time. Apparatus to perform the method for producing the first primary roll (8) and for determining the amount of material available on a primary roll for producing smaller secondary rolls (12) is also provided.

Abstract: A discharge device for operation in a gas at a prescribed pressure includes a cathode having a plurality of micro hollows therein, and an anode spaced from the cathode. Each of the micro hollows has dimensions selected to produce a micro hollow discharge at the prescribed pressure. Preferably, each of the micro hollows has a cross-sectional dimension that is on the order of the mean free path of electrons in the gas.      Electrical energy is coupled to the cathode and the anode at a voltage and current for producing micro hollow discharges in each of the micro hollows in the cathode.      The discharge device may include a discharge chamber for maintaining the prescribed pressure. A dielectric layer may be disposed on the cathode when the spacing between the cathode and the anode is greater than about the mean free path of electrons in the gas. Applications of the discharge device include fluorescent lamps, excimer lamps, flat fluorescent light sources, miniature gas lasers, electron sources and ion sources.

Abstract: A method for detecting ionizing radiation by allowing the radiation to affect the surface of the floating gate (13) of a MOSFET transistor (10) through an air or gas space. For this purpose, an uncovered area (17) is formed on the surface of the floating gate of the MOSFET transistor forming the detector. The MOSFET transistor is used so that a charge is formed on its floating gate, the charge changing as a result of the ionizing radiation the transistor is exposed to.

Abstract: The invention concerns a method and an equipment for treatment of a liquid flow to be cleaned and passed into a flotation plant or equivalent. In the method, a part of the liquid flow to be cleaned that flows along the flow line, or cleaned liquid coming from the outlet of the flotation plant, is passed along a first branch line as a liquid flow into a pump. The suction capacity of the pump is regulated so that the pump sucks gas as a flow, the gas that has been sucked into the pump being mixed with the liquid flow flowing in the first branch line, and further mixing of the gas and liquid take place in the discharge pipe of the pump. The mixed flow of gas and liquid is passed along the discharge pipe of the pump into a mixing part, where the discharge pipe of the pump ends in a pressure release. The rest of the liquid flow to be cleaned is passed along a second branch line as a liquid flow into the mixing part, where the liquid flow flowing along the second branch line is mixed with the liquid flow flowing in the discharge pipe of the pump, in which case, in the mixing part, out of the flow that is discharged from the pressure release, the gas bubbles in the liquid flow that contains dissolved gas are released. The liquid flow discharged from the mixing part is passed as a flow along a mixing duct into the flow line of the liquid flow to be cleaned and further as a flow into the flotation plant or equivalent.

Abstract: The invention is concerned with an integrated process aiming at short cycle- time material integration in a sequential operation, using different processing methods as well as material preform types (neat polymer and polymer-based composites). Traditionally each material preform type and processing step is developed by separate companies and semi - products are delivered to the next link in the conversion chain. The proposed concept includes novel preform preparation techniques as well a s a methodology for integration of the potential conversion steps for composite manufacturing, from fibre and matrix to finished part. Material and process integration opens interesting perspectives in design freedom and economical production of complex shaped parts exhibiti ng multifunctionality and well optimized performance. A unique and flexible integrated equipment is described combining various processing techniques and consequently several material processing steps can be selected.
