A method for determining silver concentration in a solution is disclosed. This method generally comprises immersing a substantially pure, elemental, copper strip in a sample of the solution to be tested, agitating the strip in the sample, removing the strip from the sample, and observing the color change, if any, of the strip.

A TV receiver preliminarily measures and stores, in a memory, data of best receiving directions, each giving maximum signal intensity, of a multi-directional antenna for receivable channels. When the antenna rotationally shifts physically for some reason, one channel is selected and subjected to measurements by an omni-directional scanning again to determine a new best receiving direction. A receiving direction number difference between the stored best receiving direction and the new best receiving direction of the same channel is determined. Using the receiving direction number difference for the one channel, all data stored in the memory are renewed at one time, the data being the best receiving direction numbers and the signal intensities therefor for all the channels. The antenna direction can be quickly adjusted to the rotational shift by new measurements for one channel, without requiring time to make unnecessary measurements for all channels, achieving a best receiving condition steadily.

A matrix type bus connection system has a plurality of master devices and a plurality of slave devices. Each slave device has an arbitration circuit. The arbitration circuit stores an address of a master device that made the access the last time, and continues holding a select signal to a selector when access ends. If a new connection request is received, the arbitration circuit compares the address of the master device that is now making the access request with the address of the master device that made the access the last time. If the connection request is from the same master device, a connection control is not performed. The previous connection status is maintained. Thus, the master device can be connected to the slave device without a delay.

In an optical disk recording apparatus, a monitor monitors a recording power of a laser light. A laser control circuit enables a laser diode to perform test recording while using the monitor to monitor the recording power of the laser light and while controlling a laser drive voltage, so that the monitored recording power reaches a given reference value during the test recording.

A main controller allows the laser control circuit to set the calculated initial laser drive voltage and to start the recording while supplying the laser control circuit with the target value so that an actual recording power of the laser light promptly reaches the target value during the course of the recording.

Disclosed is a printing apparatus capable of safe high-speed leakage detection and contact detection of a printhead. The leakage detection and contact detection are executed in the apparatus which prints on a printing medium by scanning a removable printhead mounted to a carriage. When the printhead is mounted, connection with a capacitor used in normal printing is disconnected, a lower voltage is applied to drive a printing element and monitor the voltage. If the monitored voltage is not less than a predetermined threshold, occurrence of a poor contact is determined. This is performed for electric contacts one by one. During the operation, a lower voltage is applied at a predetermined timing to drive a printing element and monitor the voltage. If the monitor voltage is not higher than a predetermined threshold, occurrence of current leakage is determined.

A mobile communication terminal holds a frequency cancellation list that is information related to cells that cannot be connected, and controls execution / non-execution (frequency cancellation) of the cell search according to the content of the cancellation list. In a case where a frequency is not assigned in a unified manner (when a frequency is assigned to different communication providers in some cells), a frequency cancellation time is set shorter than a case where the frequency is assigned in a unified manner. For example, a frequency f3 is rejected in a cell represented by “another” surrounded by a broken line when the mobile communication terminal moves from an area A to an area B. When the mobile communication terminal further moves to an area C, the frequency cancellation process initiated in the area B terminates. This is because a short frequency cancellation time is set. Therefore, the frequency cancellation time expires while the mobile communication terminal is moving from the area B to the area C. The frequency cancellation terminates, so as to be connectable in the area C of the frequency f3.
