Abstract: An APD according to the present invention comprises a substrate (1A) formed of n⁺-type Al x Ga 1-x Sb or Al x Ga 1-x ­Sb y As 1-y  semiconductor, whose aluminum content ratio x is typically 0.1 to 0.3; a light absorbing layer (2) formed of n-type GaSb semiconductor on the substrate; an avalanche multiplication layer (3,3˝) formed of n-type Al x Ga 1-x Sb or Al x Ga 1-x Sb­ y As 1-y  semiconductor, whose aluminum content ratio x is from 0.02 to 0.1, typically 0.065, so that an ionization rate ratio of positive and negative carriers is essentially maximized by a resonant ionization phenomena; and a p⁺-region (5) formed in a surface layer (4A) formed of n⁻-type Al x Ga 1-x Sb or Al x Ga 1-x Sb­ y As 1-y  semiconductor on the avalanche multiplication layer or directly in the avalanche multiplication layer so as to form a pn junction. Electrodes (6,7) are formed on the p-type region and the substrate so as to apply a bias voltage to the APD. Via an opening of the electrode (7) for the substrate, a light to be detected is injected through the substrate, while producing no carriers therein, into the light absorbing layer. The avalanche multiplication layer (3,3˝) generates the resonant impact ionization purely with only the positive carriers from the light absorbing layer (2), thus, low noise as well as fast operation of the APD is achieved. Furthermore, the APD structure of the invention facilitates the APD design.

Abstract: An exhaust gas turbine generator apparatus for diesel engines, especially for ships' diesel engines with or without a shaft generator and for combined shaft generator-motor and generator operation with or without frequency-decoupled invertors. An excess part of the diesel engine exhaust gases is supplied to a power turbine. In order to optimise the energy saving, an externally-excited synchronous generator (turbo generator), driven by the power turbine via a step- down transmission, is used which supplies the energy, via a network switch, into a network or to a synchronous shaft generator of the diesel engine. A resistor, which can be driven via an antiductor, for loading the turbo generator in the event of the network load dropping out, is dimensioned such that it is less than the nominal reactance of the turbo generator. Before the turbine is started and the exhaust gas flap is opened, the generator is excited, the antiductor is turned on and the network switch is opened. After opening of the exhaust gas flap, the frequency of the turbo generator is driven up to that of the insular network or of a shaft generator by means of the antiductor, by frequency regulation and control of the load current in the load resistor, and is synchronised via the network switch (S1). <IMAGE>

Abstract: A sensor element has a fine-line forming thin film (35) of a conductor formed on a non-conductive substrate (34), and a change of physical properties of the substrate or the ambient environment is detected through a change in physical properties of the conductor. The element is manufactured by forming a layered film, composed of a semi-conductor and a conductor, on the substrate, and forcibly diffusing part of this film to form this part into an alloy semi-conductor, thereby providing a two-dimensional pattern of the fine-lines of the conductor and the semi-conductor. By arranging a plurality of fine lines (35) of a condcutor transversely to a direction of growth of a crack in the substrate, crack in the substrate is detected through a change in electrical resistance of the fine lines. The sensor is also applicable as a dissolved oxygen sensor, and a hydrogen sensor, as well as an electrical conductivity sensor. Such sensors can be used in controlling the water chemistry of a nuclear reactor.

Abstract: Fast electromagnetic trip units having impact armature plungers and an electrical trip coil, through whose winding a load current flows, have a relatively large-volume permanent magnet which holds the impact armature plunger, which consists of a ferromagnetic material, in the stressed position against the influence of a storage compression spring. As a result of the high retention force of the permanent magnet, the behaviour of the spring characteristic of the storage compression spring is influenced unfavourably on stressing of the trip unit. The fast trip unit is thus constructed such that, on stressing of the trip unit, on the one hand a favourable behaviour of the spring characteristic is produced and, on the other hand, a high retention force is produced with a minimal magnet volume. This is achieved by a magnet core (4) in the form of a tubular sleeve consisting of a ferromagnetic material projecting from the lower pole plate (5) of the magnet housing (3) and passing coaxially through the trip coil (2) over its entire length, the impact armature plunger (6) consisting of a non-magnetic material and the permanent magnet (8) being arranged on the impact armature plunger (6) above the trip coil (2), with an air gap (20) opposite the wall of the housing (3), such that, when the fast trip unit is in the stressed state, the magnetic circuit (22) from the permanent magnet (8) is closed via the magnetic core (4), the lower pole plate (5) and a lower part (3a) of the housing (3) surrounding the trip coil (2), while, in the unstressed or tripped state, the magnetic circuit (22a) is short-circuited between the permanent magnet (8) and an upper, narrower housing projection (15). As a result of such a design, the assembly of the quick trip unit can also be considerably simplified and hence made more cost-effectively. <IMAGE>

Abstract: Disclosed are a method of and an apparatus for controlling exposure in halftone photography by calculating a main exposure amount (T M ), a bump exposure amount (T H ) and a flash exposure amount (T F ) based on basic data peculiar to the combination of a screen (36) and a photosensitive material (37) original data depending on an original (35) in a process camera. The method includes the steps of preparing the basic data and the original data, obtaining a dot image by exposing the original (35) to a photosensitive material (37) through a screen (36) based on the prepared basic data and original data, defining a resultant dot percentage correction value by obtaining differences between dot percentages of the portions of the obtained dot image which portions corresponding to a highlight region and a shadow region of the original, respectively, and the respective desired values, and correcting at least one of the main exposure amount (T M ), the bump exposure amount (T H ) and the flash exposure amount (T F ) based on the resultant dot percentage correction value and the basic data. The difference between the dot percentage of the dot image obtained as a result of the exposure and a desired value can be used as a correction value, and therefore, a dot image having a desired dot percentage can be obtained without requiring a difficult procedure of evaluating a correction result.
