Title: Video camera using solid-state image sensor
Inventor: KAMIKUBO MASAFUMI
IPC: H04N5/357
Filed: 1987-07-09
Abstract: PURPOSE:To attain the reproduction of an excellent image by dividing a read area of a solid-state image sensor into N equally and reading a signal from one split read area in a time shorter than 1/N of the one field period and stopping the readout of the signal at the head changeover period. CONSTITUTION:The read area of the solid-state image sensor 14 is divided equally into N and a signal is read from one split read area in a shorter time than the 1/N of the one field period while the head scans a video tape to apply read control of the solid-state image sensor 14 thereby stopping the signal readout in the head changeover period at least. That is, a signal sent from the solid-state image sensor 14 is compressed more than the real time and the compressed signal is recorded on the video tape and the signal reproduced from the video tape is A-D converted once and the result is stored in a memory thereby adjusting the readout time and expanding the time into the real time. Thus, the image is reproduced with excellent quality.

Title: Elecromagnetic balance
Inventor: YANO SHIYOUZOU
IPC: G01G1/29
Filed: 1980-12-01
Abstract: PURPOSE:To reduce the effect of disturbance to improve the stability of measurement, by separating force coils into the one containing a differential element and the one not containing the same and by finding a load from the current flowing to the force coil not containing the differential element. CONSTITUTION:An output from a displacement sensor 2 which changes according to the load is amplified by a pre-amplifier 3 and divided in two. One of the divided output is inputted in the first adjusting meter 41 containing a proportional element P and an integrating element I through the intermediary of a circuit 8 which can vary gain automatically and then is transmitted to the force coil 61 through a power amplifier 51. The amplitude of the circuit 8 is increased in proportion to an input. The other output is inputted in the second adjusting meter 42 containing a differential element D and is transmitted to the force coil 62 through the intermediary of a power amplifier 52. Only the current i of the force coil 61 is taken out as the output of the balance. Minute fluctuations caused by the disturbance such as a wind and vibrations are damped by the force coil 62. By this constitution, the effect of the disturbance is avoided without losing the responsiveness to an input, whereby the stability of an indication  is improved.
