The substrate processing apparatus is provided with a gas-liquid mixing nozzle for generating a gas-liquid mixture by mixing a liquid and a pressurized gas, to discharge the gas-liquid mixture to a substrate at high speeds. The mixture process is conducted in an open space out of the nozzle, and change in the supply pressure of the gas does not affect the supply of the liquid. The reaction products which having been generated on the substrate in etching process is removed at high speeds with the flow of the gas-liquid mixture, whereby the quality of the process is improved.

A circuit board assembly containing two pluralities of busbars or wires arranged in a lattice configuration, there being electrical continuity at each of the intersecting points. Slits are provided on each of the busbars which engage each other to complete the lattice. In the case of wires, they are bonded to each other. The conductive member thus formed may be sandwiched between two insulative films and is placed on an insulative plate which, in turn, is enclosed by an electrical connection box. The configuration provides substantial advantages in economy of production, simplified equipment required, and ease of altering the circuitry.

A receiver such as a liquid crystal display television receiver, which a user carries with him, is used for learning at sight which television stations at a destination supply broadcasting service. The receiver performs automatic tuning operation of television signal waves to search available television channels, stores searched available television channels in a memory device, and displays a list of the available stored television channels. The receiver displays the available television channels stored in the memory device, and successively receives the available television channels, thereby displaying the television programs for a predetermined period. The receiver is equipped with a memory in which local areas, local television stations in the areas, frequency data and network relations between key stations and the local television stations are memorized. When an area memorized in the memory is designated, a station-selecting guide information is displayed, which indicates a network relation between the local television stations and the key stations. The receiver selects an arbitrary television station and detect the signal receiving intensity, and stores data of the selected television station and the relevant signal receiving intensity in the memory device. The receiver displays a channel number and frequency data of the selected television station in a displaying manner associated with the detected signal receiving intensity.

A superminiature microphone device includes a hollow body in the form of a decorative clothing accessory, a microphone unit including lead wires within the body, and a plug connected by the lead wires to the microphone unit wherein the plug has at least one pin-shaped terminal. A cord connector including a conical collet chuck is arranged to receive the pin-shaped terminal of the microphone unit plug from behind an article of clothing such as a necktie. A clamp member is arranged around the tip portion of the chuck for clamping the chuck about the plug terminal in response to a spring force. Accordingly, an electric cord can be routed from the connector behind the article of clothing so as to connect the microphone unit with an outside device so that the wearer's appearance is not affected by the presence of the connection cord.

A tape recorder with means for displaying a time by normal and stopwatch modes is provided with a time signal generator, a first time data generator coupled with the time signal generator to produce first time data of normal mode, and a second time data generator coupled with the time signal generator to produce second time data of stopwatch mode. The tape recorder is further provided with a decoder to which the first and second time data are selectively applied and which converts the time data into time data for display, and a display unit for displaying the output of the decoder. A first switch actuated when the tape recorder operates in record and play modes and a second switch for changing a normal mode time display over to a stopwatch mode time display and vice versa are further included in the tape recorder. When the second switch is turned to the normal mode time display, the normal mode time data is displayed by the display unit regardless of the actuation of the first switch. When the second switch is turned to the stopwatch mode time display, the second time data generator is cleared and generates a second time data elapsed from the time point that the first switch is actuated. The second time data generated is displayed by the display unit.

A coupling device comprises a pair of coupling channels formed in the both lateral sides of a compact cassette tape recorder, and a pair of rails formed on a part of a radio set for engagement with the channels, allowing the cassette tape recorder to be detachably coupled with the radio set. When not coupled, apertures provided in the tape recorder for connection terminals are covered by a coverplate, which uncovers these apertures by a sliding movement as the tape recorder is coupled with the radio set, thus enabling an electrical connection with the latter. The compact tape recorder can be detachably coupled with an accessory unit such as a tuner, a microphone pre-amplifier or the like by a single mounting threaded stud.

Burner arrangements for staged combustion to decrease nitrogen oxides (NOx) during the combustion of hydrocarbon fuel with air. The burner arrangements have a combustion into which hydrocarbon fuel and less than 70% of the stoichiometric air are introduced, and a path for the secondary air around the combustion chamber. A flame holding means is provided in one end of the combustion chamber to stabilize the substoichiometric combustion so that a partially burned gas containing mainly H.sub.2 and CO as combustible components is obtained. The combustion chamber has an exit, and there is an exit from the secondary air path near the exit of the combustion chamber. A discharging means for the partially burned gas is provided at the exit of the combustion chamber to vary the pattern of the flow of said partially burned gas by converting the enthalpy of said partially burned gas into kinetic energy. A discharging means for the secondary air is also provided at the exit for the secondary air to vary the pattern of the flow of the secondary air.

A radiation detecting apparatus of this invention includes an arithmetic processing device which carries out arithmetic processes for drawing boundaries based on peaks of signal strengths and separating respective positions by the boundaries, and for determining, by using spatial periodicity of the peaks, the number of peaks having failed to be separated, with a plurality of peaks connecting to each other. If the separation fails with a plurality of peaks connecting to each other, the number of peaks in error is determined using spatial periodicity of the peaks. Thus, by using spatial periodicity of the peaks, the number of peaks in error can be determined and boundaries can be set easily. As a result, incident positions can also be discriminated easily, and detecting positions of radiation can be determined easily.
