Title: Electric photograph copier
Inventor: MAEKAWA ETSUICHI
IPC: B65H5/02
Filed: 1989-02-03
Abstract: PURPOSE:To prevent giving damage to a long-sized document in an automatic document sender by withdrawing a stopper for stopping the document while continuingly ejecting the supply of the document when the document is detected to be long-sized. CONSTITUTION:When a copy button is pushed, in an automatic document sender 21, a carrier motor 68 is rotated and a first document is carried by a carrier roller 59, while a plunger 65 is excited and a stopper 63 is protruded. When the edge of the paper sheet passes through an optical sensor PS1, a timer built in a controller 200 is started. The controller 200 judges the document as long- sized when the passing time of the timer exceeds the specified maximum size level, and the excitation of the plunger 65 is cut. A stopper 63 is then withdrawn from the surface of a paper sheet glass board 2, while a driving motor 69 as well as a belt 53 by which a belt 53 is driven, are kept on working, whereby the long-sized document passes through a guide 66 and is ejected on an ejection board 67. When the finishing of the ejection is detected by an optical sensor PS2, the motors 68, 69 are stopped.

Title: Ink jet printer
Inventor: FURUKAWA ISOKAZU
IPC: B41J2/01
Filed: 1981-02-20
Abstract: PURPOSE:To improve the quality of pictures with a greater universality of a printing paper by changing the mass of ink drops injected from an ink jet head according to hygroscopic property and seeping property of the paper. CONSTITUTION:A nozzle section of an ink jet head 1 is composed of a piezo- electric element 15. When a voltage is applied on electrodes 16 and 17 of the piezo-electric element 15, a slide diviation occurs in the thickness thereby enabling the control of the real diameter of a nozzle hole 2. In other words, when the hygroscopic property or the seeping property is high, a nozzle diameter controlling power source 13a relatively high in the source voltage, while it is relatively low, the nozzle diameter controlling power source 13b relatively low in the source voltage is selected. In this manner, the real nozzle diameter is adjusted properly. In the case of a deflection type, charge compensation voltage generation circuits 21a and 21b also are switched over to compensate for possible deflection strain.

Filed: 1992-02-10
Abstract: PURPOSE: To improve the labeling speed and efficiency by including an air jet mounted non-vertically on a rotary vacuum drum for attaching a label and the like onto a rotating container. CONSTITUTION: The containers 6 are conveyed by a conveyor 22, independently engaged with a star wheel 24 and sent along a tangent to the circumference adjacent to a vacuum drum 32. Simultaneously a label is supplied from a roller 28, and cut into segments by a cutter 31 in a state that its rear surface is exposed. A front surface side of the cut label is sucked by the vacuum drum 32, and coated with an adhesive agent on its front edge part and with a solvent on its rear edge part by a wiper assembly 34. The vacuum drum 32 comprises a plurality of vertical air jet passages 82, which apply vacuum or positive air pressure to a front edge portal 111. A front edge of the label is forcibly separated from the drum 32 by the air jet generated from the front edge portal 111 of the drum 32 to assist the movement of the label from the vacuum drum 32 to the container 6.

Title: Soft starting circuit
Inventor: SUZUKI TETSUYA
IPC: G05F1/46
Filed: 1983-02-16
Abstract: PURPOSE:To use effectively a thyristor without increasing unnecessarily the inclination of a soft start by applying the constant voltage to a time constant circuit of a soft starting circuit which controls the angle of continuity when the thyristor is driven. CONSTITUTION:When the maximum set voltage is applied between set voltage input terminals 21 and 22, an output corresponding to the time constant set by a resistor 28 and a capacitor 29 is obtained from an output terminal 25 via the emitter of a transistor 30 of an emitter follower. When the variable voltage higher than the set voltage is applied to the terminals 21 and 22, an output is obtained in the same way. Then the potential of the juncture between resistors 23 and 24 is higher than the emitter potential of the transistor 30 when the output obtained from the emitter of the transistor 30 reaches the set voltage. Thus the transistor 30 is turned off. Hereafter the output voltage is set at a set level.

Filed: 1988-02-04
Abstract: PURPOSE:To prevent the intrusion of dust into a vacuum sealing part of a CZ-process single crystal production apparatus having a structure to vertically move a crucible shaft with bellows attached to a growth chamber at one end, by introducing an inert gas to a region near the vacuum sealing part attached to the other end of the bellows, thereby increasing the pressure in the region relative to that of the growing chamber. CONSTITUTION:An end of belows 6 for the vertical movement of a crucible shaft 4 is hermetically connected to a growth chamber 1 and the other end is hermetically connected to an end plate 7. The crucible shaft 4 is extended through the end plate 7 and vacuum seals 8, 9, 10 are formed at the through part. A circular disk 13 fitting to the crucible shaft 4 is placed at the inner side of the end plate 7 and an inert gas is introduced through an inlet port 14 into a space formed between the circular disk 13 and the end plate 7. Molten liquid is put into the crucible 3 placed in the growth chamber 1 and a single crystal is pulled up and grown by CZ process. The pressure in the above space is increased relative to that of the growth chamber 1 by this process to prevent the intrusion of dust into the vacuum sealing part.

Title: Photographic lens of high aperture ratio
Inventor: OKUDAIRA SADAO
IPC: G02B9/00
Filed: 1983-02-16
Abstract: PURPOSE:To correct the coma aberration which is generated when astigmatism is corrected sufficiently, by giving a refractive index distribution to a lens element in the optical-axial direction. CONSTITUTION:When the distribution refractive index of the second positive meniscus lens is reduced monotonously from the object side to the image side, the power of the third face for the light which passes through the peripheral part of this second positive lens is weakened, and thus, this method is effective for correction of the coma aberration. If a variation DELTAN of refractive indexes of the second positive lens and the third negative lens is smaller than 0.0004f (f is the focal length (mm.) of the whole of the system), it is difficult that this method has not a sufficient effect though there is an advantage in the working and if the variation DELTAN is larger than 0.06, it is difficult that lenses are produced easily with a current producing technique.

Abstract: PURPOSE:To suppress the rush current at the starting time and to interrupt a circuit rapidly at the abnormal time by inserting a resistor of the suitable value to a protecting circuit separate from a circuit, through which a main current flows. CONSTITUTION:When an AC power source 1 is applied at the starting time, a charging current flows to a condenser 7 through a circuit protector 2c, a resistor 5 and a rectifier 6, and the voltage across the condenser 7 gradually rises.
