Title: Resonant inverter controller, and vehicle device using inverter
Inventor: FURUKAWA KATSUHIKO
IPC: B60R16/03
Filed: 2001-07-02
Abstract: PROBLEM TO BE SOLVED: To provide an inverter controller, which controls a resonant soft- switching inverter circuit having reduced inductance for resonance, according to its principle of operation. SOLUTION: When a rotational angle θ of a motor exists, for example, in the area 1 of a space vector, a control CPU 5 outputs an output voltage vector V1 at the time t00 for an interval (T1); and next at a time t01, it transits to an output voltage vector V4 and outputs the vector for a time (T3/4), and at the time t02, it transits to an output voltage vector V3 and outputs the vector for a time (T2+T3/2). After outputting the output voltage vector V3, it retransits to an output voltage vector V4 at a time t03 and outputs the vector for an interval (T3/4), and then it repeats the output, in order of output voltage vectors V1, V4, V3, and V4. Since the zero vector is a value obtained by subtracting the output time of the output voltage vector from the output time of the output voltage vector V3, it follows that T2+T3/2-(T3/4+T3/4)=T2.

Title: Solid-state imaging apparatus
Inventor: MABUCHI KEIJI
IPC: H04N5/372
Filed: 2001-07-03
Abstract: PROBLEM TO BE SOLVED: To extend the dynamic range of a solid-state imaging apparatus. SOLUTION: A timing generator allows a sample-hold circuit 2 to hold an output voltage of a buffer circuit 130 before supplying a reset pulse 134 to a reset gate 128. In this reset range, when much luminous quantity is incident onto a photo diode 122, electric charges generated by the photo diode 122 overflow from the photo diode 122 to an FD(Floating Diffusion) section 124 and also overflows from the FD section 124 to a power supply Vdd. In this case, a voltage of the FD section 124 depends on a current by electric charges flowing to the power supply. Since the reset gate 128 has a small current flowing to a channel and operates at a sub threshold region, a voltage of the FD section 124 is a value corresponding to the logarithm of the current. Then the voltage held by the sample-hold circuit 2 is a value corresponding to the logarithm of the luminous quantity.
