Title: Power control circuit for television picture receiver
Inventor: YUDA MINORU
IPC: H04N3/18
Filed: 1978-07-31
Abstract: PURPOSE:To reduce the power loss as well as to ensure the steady operation of the load by turning off the switch circuit through detection of the fact that the charge voltage of the capacitor becomes lower than the rectification output voltage of the flyback transformer. CONSTITUTION:Output voltage V11 obtained through rectification of the commercial AC power source is charged by capacitor C1, and the change voltage detection circuit in control circuit 25 detects the fact that the charge voltage has reached the fixed level. With the detection signal of the charge detection circuit, switch circuit 22 supplies the charge voltage of C1 to the load. Here in case the charge voltage of C1 becomes lower than voltage V22 of terminal 24 which rectified the output horizontal pulse supplied from the flyback transformer, the detection circuit in circuit 25 detects this to turn off circuit 22 as well as supply voltage V22 to the load via output terminal 23. Thus the power loss can be reduced, ensuring the steady operation of the load.

Title: Magnetic recording and reproducing device
Inventor: MARUYAMA AKIRA
IPC: G11B15/48
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To prevent a tape slacking and an excessive tensil strength from being caused by detecting tape winding diameters and revolving speeds of respective tape reels at the time of FF/REW and calculating angular momentums of the reels to calculate proper braking timings. SOLUTION: When the instruction of FF/REW is issued, the fast revolving of a capstan motor is performed once in the mode of a reproduction/reversal reproduction and respective tape winding diameters are calculated from respective revolving speeds detected by a revolving speed of capstan motor detecting means 201, a revolving speed of S reel detecting means 202 and a revolving speed of T reel detecting means 203. Respective angular momentums are calculated from calculated winding diameters and revolving speeds of the reels and when an stop instruction is issued, a time difference of braking timings braking both reels is set based on the angular momentums. The setting of the time difference is performed step-wise by dividing the angular momentum into prescribed divisions every reel and according to respective divisions.  Moreover, the time difference can be set continuously by expressing it as the function of the angular momentums of both sides.

Title: Wet type developing device
Inventor: TSUKAMOTO TAKEO
IPC: G03G15/11
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To make the density of an image uniform by changing the revolving speed of a surplus liquid removing means, in accordance with the displacement of the gap between a latent image carrier and the surplus liquid removing means. SOLUTION: The rotational speed of the driving motor of a squeezing roller 9 is controlled according to the displacement of the gap by a period of the squeezing roller 9. In other words, in a part, where a gap distance is long and the quantity of surplus developer on a photoreceptor drum 1 is larger, the quantity of liquid removed by the squeezing roller 9 is larger and the thickness of the liquid on the drum 1 is constant. On the other hand, in the part where the gap distance is short and the quantity of the surplus developer on the drum 1 is smaller, the removed liquid quantity is smaller and the thickness of the liquid on the drum 1 is constant.  Thus, the displacement of the thickness of the liquid on the drum 1 caused by the displacement of the gap between the drum 1 and the squeezing roller 9 is offset by the displacement of the quantity of the liquid removed by the squeezing roller 9, so that the thickness of a carrier film on the drum 1 after the squeezing roller 9 passes through becomes almost constant.
