Title: Load electric power stabilizer
Inventor: NAGASAWA KIYOTO
IPC: G05F1/455
Filed: 1979-12-03
Abstract: PURPOSE: To obtain light output stability of high precision by detecting a lamp- voltage effective value by making use of the linearity of FET.  
     CONSTITUTION: The voltage across tangsten lamp L, after being full-wave-rectified REC, is voltage divided and applied to gate G of FET. For example, if the lamp voltage rises, voltage Vg also rises. Then, output voltage Vo of FET drops by the increment of the effective value of Vg and output VL of integral network INT also decreases. This output VL is compared with reference voltage VA by amplifier AA and according to the difference, the output voltage rises and is compared with a saw-tooth wave by comparator COMP. Its output is led to trigger pulse generator PG, whose output phase increase the cutoff phase angle of triac TRC and the lamp voltage drops accordingly and nears a constant value. Thus, light output stability of high precision can be obtained.

Title: Orientation device for shorter circuit
Inventor: HINO KIYOSHI
IPC: G05D3/00
Filed: 1986-07-03
Abstract: PURPOSE:To easily decides the forward or reverse rotation of an output shaft of a motor to secure a shorter circuit right after application of a power supply, by dividing the rotational range of said output shaft into two parts and delivering different signals through these two ranges. CONSTITUTION:An output shaft 1 revolves against the position of an original point and stops at a position where a slit disk 2 tilts in the counterclockwise direction by theta. Under such conditions, an circular arcuate slit 2a is formed between a 2nd LED 6 and a light receiving element 7 and a pulse of a H level is delivered. In other words, a shorter circuit is always secured to the original point by revolving the shaft 1 in the counterclockwise direction X1 as long as the slit 2a is set opposite to the original point. That is, the time needed for rotation within a range shown by the clockwise rotation Y1 is much shorter than the time needed for rotation in a range X1. Thus it is possible to easily decide the forward or reverse rotation to reset the shaft 1 to the position of the original point with the minimum angle according to the presence or absence the signal S given from a pulse generating means set at the original point position.

Abstract: PURPOSE:To eliminate the need for the input means of a 1st device by transferring information to a request source on condition that the information whose information transfer request source is a transfer destination is already inputted, and waiting for the information to be inputted and transferring it to the information transfer request source in other cases when a request to transfer the information is sent from the 1st device to a 2nd device. CONSTITUTION:The request to transfer information from the 1st information processor 1a is transferred to the 2nd information processor 2 through a transmission line 9 and when the information is passed to a CPU, it is checked whether or not information addressed to the transfer destination is already inputted. When the information specified by the information transfer request is already inputted, its image information is read out to a RAM from a storage address that a management table indicates by file length that the management table indicates and before the read is completed, a communication control part transmits the image information to the specified transfer destination in order from image information which is read first. The 1st information processor 1a receives and stores this information in a RAM and then performs image insertion, etc., thereafter according to an application program.

Abstract: PURPOSE:To eliminate the instability of image quality and to decrease the wasteful consumption of a carrier by providing a means for determining whether the simultaneous exchange of the developers in all developing tanks is necessary or not. CONSTITUTION:Means 11, 13 for detecting the number of image forming times which detect the number of the image forming times by using the same developer are provided to each of the developing tanks.

The display to urge the exchange is, therefore, executable before the electrostatic chargeability of the developers is degraded at such a time when, for example, the number of use times of at least one developing tank attains the number of the limit use times slightly more than the number of the use times or when the average of the number of the use times of all the developing tanks attains 10,000 sheets or at the exact timing for the exchange by comparison with the developer which does not attain the number of the use times to the exchange. The fluctuation in the electrostatic chargeability, the wasteful consumption of the developers and the wasteful operation of maintenance, etc., are thereby eliminated.
