Title: Pulse duration control meter
Inventor: HIRANO MASAHIRO
IPC: G05B11/26
Filed: 1979-09-10
Abstract: PURPOSE: To realize a free control for the roughness and the fineness of the control property, by securing a proportion between the hysteresis width of the control system and the deviation of the input signal.  
     CONSTITUTION: The deviation ε between the input signal E i  and the set value E s  is supplied to the comparators OP 3  and OP 4  which have the hysteresis respectively. When the deviation ε larger than the hystresis is supplied, the SW 1  or the SW 2  is turned on. The deviation ε is supplied also to the hysteresis width setting circuit 6 to produce the output voltage E a  and E b . Both the E a  and E b  have a size proportional to the ε respectively and then added to the voltage of the input terminal of the comparators OP 3  and OP 4 . As a result, the change proportional to the ε can be applied to the hysteresis width. Furthermore, the ε is integrated by the capacitor CI, and the integrated voltage is added to the outputs of the OP 3  and OP 4  to be used as the feedback voltage. Thus the deviation voltage is increased virtually to secure the response although the ε is minute.

Title: Production of target for x-ray tube
Inventor: KOIZUMI HIDEO
IPC: H01J9/14
Filed: 1977-09-28
Abstract: PURPOSE: To enable the traget for X-ray tube to be used stably over a long period of time by subjecting the substrate of molybdenum to hot degassing treatment in a vacuum of high temperature.  
     CONSTITUTION: After molybdenum powder is compaction-formed, this molding is hot sintered at 2000 to 2500 °C in a vacuum. At this time, this is accomplished at a drgree of vaccum of preferably more than 10 -3  torr in order to enhance gas emissivity. The Mo sintered body obtained in this way is forged to form a plate form body of a high density. Molybdenum paste is deposited between the plate form body of Mo obtained in this way and a plate form body of w and both are bonded by hot-pressing or the like and the plate form is fabricated to disc form. Further the disc is subjected to heat treatment at above 2000°C in a vacuum. Hence, the gas remained in the disc body is emitted and the target which will not cause blackening and abnormal discharge and cause less attenuation of X-ray generation despite long term use may be obtained

Title: Developing device
Inventor: TAJIMA HATSUO
IPC: G03G15/08
Filed: 1979-09-11
Abstract: PURPOSE:To obtain a visible image which excels in the sharpness with no uneven development and in a high gradient, by securing the gap between the electrostatic holder and the development roller in such way that the surface of the nonpicture part has a contact at the picture part and no contact on the surface of the toner particle layer on the roller each. CONSTITUTION:A gap is secured between the electrostatic holder and the development roller 11, and the length of the gap is set larger than the toner coated layer on the roller 11. At the same time, a mutual friction charging is secured between the toner and the carrier via the stirring component. The magnetic roller 8 consists of the rotatable nonmagnetic sleeve 9 plus the magnet 10 fixed into the sleeve to form the magnetic brush along with the toner and the carrier and then transport the toner and the carrier. For the toner and the carrier transported, only the toner sticks onto the surface of the roller 11 at the position where the toner and the carrier touch or approximate to the roller 11 and by the repulsive power between the toners themselves and the reflection force together. In such way, a high-contrast picture can be obtained with no uneven development and a high gradient.

Title: Picture forming method
Inventor: YOSHIDA NORITOSHI
IPC: G03G13/00
Filed: 1979-09-11
Abstract: PURPOSE:To obtain a stabilized picture without any special device constitution, by avoiding the use of the secondary latent image produced by the initial modulation and on the picture receiving medium for the picture formation in the device which uses the screen-type photoreceptor and the picture receiving medium. CONSTITUTION:The ion current is modulated on the picture receiving medium by the primary latent image of the screen photoreceptor, and then the secondary latent image on the picture receiving medium is developed. Then this developed picture is copied onto the sheet component. In such method, the modulation is carried out in many times with use of the same primary latent image, and thus a picture is obtained. In such case, the concentration of development is lowered at the first time or several subsequent times of modulation. The concentration is low in particular at the first modulation. The development is paused for formation of the picture during the low-concentration times, and then the load is eliminated for the cleaning means. Furthermore, the supply of the copy sheets is stopped to save the copy sheets. Thus a low-cost picture can be obtained by giving the development to the stabilized pictures at and subsequent times and without using any special device to prevent the change of the initial picture.
