Title: Picture input device
Inventor: SAKAKI KENJI
IPC: H04N5/335
Filed: 1985-11-05
Abstract: PURPOSE:To obtain picture data with high accuracy without being affected by temperatures and circumstances by providing a light shielding means for reflected light, a memory circuit storing a measured dark current at the time of blocking light and a subtractor circuit, as well as a photoelectric converter element, an A/D converter and a picture data memory. CONSTITUTION:Prior to inputting picture data to a CCD 1, a shutter 4 acts so as to block reflected light, and the dark current of the CCD 1 is caused accordingly. A read circuit 7 reads out the dark current and inputs it to the A/D converter 2. The digitized dark current is inputted to the memory circuit, that is, a RAM 5, for instance. Upon the completion of reading the dark current, the shutter 4 is opened, and irradiates the reflected light 1-3 of an object 1-2 to the CCD 1. The read circuit 7 reads out the contents of the CCD 1, and inputs them to the A/D converter 2, which inputs the digitized picture data to the picture data memory 3. The subtractor circuit 6 subtracts the contents in the picture data memory 3 and the RAM 5, and the subtracted contents turn out to be picture data.

IPC: H02J3/18
Filed: 1993-10-05
Abstract: PURPOSE:To provide a power factor improving device which can flexibly deal with the capacity of a phase advance capacitor and the combination. CONSTITUTION:A power source 1 supplies power to a load 2. Plural phase advance capacitors 3-1-3-n are parallelly connected through respective switches 4-1-4-n to this load 2. A memory 10a of an arithmetic part 10 stores the capacity of. the respective phase advance capacitors and the connecting state of the respective phase advance capacitors. Based on the outputs of a wattmeter 6, reactive wattmeter 7 and power factor meter 8 and the stored contents in the memory 10a, the arithmetic part 10 calculates the phase advance capacitor to be connected or disconnected and instructs a switch control part 11 to perform the connection or disconnection of this phase advance capacitor. In response to this instruction, the switch control part 11 selectively changes over the respective switches 4-1-4-n and connects or disocnnects this phase advance capacitor. Thus, the total capacity of the phase advance capacitors parallelly connected to the load 2 is changed, and reactive power is reduced.
