Abstract: PURPOSE:To remove a potential barrier, and to improve transfer efficiency to a horizontal transfer channel by applying different clocks to each of first, second and third gates and forming the first-third gates so that the direction that signal charges are transferred from the second gate to the third gate has the directions of two horizontal and vertical components. CONSTITUTION:When a gate on the same horizontal transfer channel 8 receiving signal charges from a second gate G2 is used as a third gate G3, first-third gates G1-G3 are shaped so that the direction that signal charges are transferred from the second gate G2 to the third gate G3 has the directions of two horizon tal and vertical components. Consequently, signal charges stored just under the first gate G1 are transferred to a potential well just under the second gate G2, and signal charges are transferred from the horizontal gate section (a) of the second gate G2 and a vertical gate section (b) as the swelling section of the second gate G2 to the third gate G3 in signal charges transferred to the second gate G2. Accordingly, channel width at a final step can be widened, thus improving transfer efficiency.

Title: Level detector
Inventor: YAMAZAKI KEIICHI
IPC: G01F23/00
Filed: 1983-07-12
Abstract: PURPOSE:To detect a specified liquid level without receiving the effect of a measuring capacitor, by connecting one of capacitors, which are connected in series, to the measuring capacitor in parallel, and connecting the parallel capacitor to a reference point. CONSTITUTION:A measuring capacitor C0 is connected in parallel with a capacitor C2, which is connected with a capacitor C1 in series, between a measuring electrode an a reference grounding point. The capacitor C2 is also connected to the reference grounding point. The resonant output of a frequency corresponding to a total capacitance C based on the expression I is outputted from an oscillator circuit 4. The detected output of a specified liquid level is generated from an output circuit 7 through a filter circuit 5 and a rectifier circuit 6. The order of the magnitudes of the capacities is C1>C2>C0. When the liquid level is not contacted with the measuring electrode, the capacity C becomes equal to the capacity C2. When they are contacted, the capacity C0 becomes infinite, and the capacity C becomes equal to the capacity C1. By the jump of the capacity C, the reaching to the specified liquid level can be detected excellently without the effect of the measuring capacitor.

Abstract: PURPOSE:To always restart an information processor in the software executing state set in the precedent power OFF state when a power supply is turned on by resetting first a ROM after replacement of a battery at its consumption and then resetting first a RAM at non-consumption of the battery respectively. CONSTITUTION:When the battery voltage drops less than a reference level in an OFF state of a power supply, a reset terminal of a flip-flop 31 is set at an H level with the Q output set at an L level respectively. That is, an interruption A calls the data on the restart of software out of a ROM 10 when a battery is consumed. While the Q output of the flip-flop 31 is kept at an H level, an interruption B calls the data on the restart of software out of a RAM 6. The interruption A or B is produced when the power supply is turned on and then finished. Thus an end signal of the interruption A or B is returned from an interruption processor 2.
