Abstract: Control method and apparatus for a manual spray gun may include a second manually actuated trigger disposed on the spray gun handle, with the second trigger being operational to select or change one or more coating operation parameters.

Abstract: A tuner receives service information SI for each of a plurality of channels included in a digital broadcasting signal at one carrier frequency. A service information extraction unit extracts and stores the received service information preset into a memory. The operator selects the service information stored in the memory and acquires a program. The tuner may have a function of automatically scanning the carrier frequency all over the receivable frequency bands and store it. The temporary service information having irregular broadcast time is stored in the memory through an operation of an operation input unit. When the temporary service information is not broadcast, such temporary service information is deleted from the memory.

Abstract: A pair of stator contacts, which are positioned inside the tuner housing and are internally connected to the AFT circuit within the tuner housing, are positioned so that unused tuning coils carried by the station selector shaft of the tuner are momentarily connected to this pair of stator contacts as the station selector shaft is moved from one detented channel position to the next. Each time a tuning coil is connected to the AFT circuit it defeats the AFT operation thereof and prevents the AFT circuit from controlling the local oscillator until the next detented channel position is reached. When the station selector shaft reaches a detented channel position at least one of the pair of stator contacts is not connected to any of the tuning coils of the tuner so that the AFT circuit is free to control the local oscillator in a conventional manner.

Abstract: This disclosure describes a continuous tuning arrangement for a variable frequency response circuit of the type covering a relatively wide frequency range. Many techniques for accommodating a wide frequency range are known and include synthesizers, waveform generators and so on which employ various coarse tuning controls or devices for band selection. A synthesizer is described which employs a continuous tuning means enabling one to continuously tune the circuit from a first frequency to a second frequency or from said second frequency to said first in a rapid manner, whereby continuous tuning is afforded without the necessity of returning the tuning control to a start position each time a new frequency is selected by the coarse tuning control.
