Patent JP-S5952246-A (JP)
Title: Exposure controller
Inventor: SAKADO KEIICHIROU
IPC: H01L21/30
Filed: 1982-09-20
Abstract: PURPOSE:To perform accurate exposure control by making an increase corresponding to the over-exposure quantity of light in the period from the starting point to the ending point of the closure of a shutter previously during the opening operation of the shutter, and taking a superposition measurement. CONSTITUTION:For example, whien the shutter 3 is closed, outputs of FFs 100 and 102 are both at a level ''L'' and counted values of counters 24 and 106 are both ''0''. In this case, when a shutter release signal S2 is at ''H'', the outputs of the FFs 100 and 102 are at ''H'', an AND gate 103 is opened, and output pulses of an oscillator 104 are outputted as a driving signal S3 through a buffer amplifier 105, so that a pulse motor 4 rotates corresponding to the pulses. At the same time, the counter 24 counts the exposure amount from the starting point of releasing operation and the counter 106 also starts counting the oscillator output pulses; when the releasing of the shutter 3 is completed, a comparator 108 outputs a coincidence pulse, the output of the FF102 goes down to ''L'', and a switch signal S4 also goes down to ''L'', so that a switch 21 is switched to the side of a contact B thereafter.

Title: Fault detector circuit for phase control oscillator
Inventor: HAYASHI KENJI
IPC: H04L7/00
Filed: 1978-12-26
Abstract: PURPOSE:To realize most of the fault detection for the phase control oscillator through a simple circuit constitution. CONSTITUTION:In case the phase control system has some fault with the free run of the output frequency, output pulse D of divider 12 entering the trigger terminal of flip-flop 16 features the cyclic phase relation of D and C' to reverse output pulse C' of divider 11. Under such phase relation, logic level ''1'' of C' of divider 11 is written into flip-flop 16 via the rise of output pulse D' of divider 12, and thus the output of OR gate 18 becomes logic level ''1''. In this case, logic level ''1'' is written also into flip-flop 17 in the same way. When the input signal of the phase synchronous oscillator is cut off, the output pulse of divider 11 is fixed to logic level ''1'' or ''0''. And the output of either one of flip-flops 16 and 17 features ''1'', and accordingly the output of gate 18 features also ''1''.

Title: Control method for mobile communication terminal
Inventor: SOTODATE YUKINORI
IPC: H04W4/04
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To automatically switch to an automobile drive mode without the need for a manual operation. SOLUTION: When a mobile set Z is resident in a cell A, the positional information of the mobile set Z or a database denotes that the set Z is resident in the cell A and time information denotes that the set Z has moved to the cell A at e.g. 10:00 hours. If the mobile set Z moves to a cell B, the mobile set Z informs the database about a new movement to the cell B at, e.g. 10:10 hour. In this case, the database calculates the time required for movement from the cell A to the cell B. Then an upper limit of the time required for the movement from the cell A to the cell B is obtained from a reference time table. When the time required actually is smaller than the upper limit, it is discriminated that the mobile set is moving at a high-speed and the service information of the mobile set is set to a state of executing the automobile drive mode.  Furthermore, when the automatic switching to the automobile drive mode for the movement from the cell A to the cell B is not desired, exception is set to an exception setting list.

Abstract: PURPOSE:To improve the shock resistance and to prevent the deterioration of characteristics due to the secular change, by forming the electrode plates to a recess surface adhered to both sides of a crystal plate and having an electrode film formed on the counter surface. CONSTITUTION:A pair of electrode plate 2 are formed with adhesion to both sides of a crystal plate 1.
