Title: Rotary head device
Inventor: SASAKI HIDEMI
IPC: G11B5/02
Filed: 1983-07-05
Abstract: PURPOSE:To obtain a rotary head device prevented from the reduction of the efficiency of transmission and the increase of the size of the device without increasing the number of times of coupling of a rotary transformer even if the number of magnetic heads is increased by providing the device with an alteration switch selectively connecting a prescribed magnetic head out of plural magnetic heads. CONSTITUTION:A signal from a control circuit 19 stops a rotary cylinder 1 on a position where the leading end part 11a of a switch working lever 11 is opposed to a lever 9 of the alteration switch 7. When current is temporarily supplied to a solenoid 16 by a signal from the control circuit 19, the lever 9 is pressed down by the leading end part 11a of the lever 11, so that the end part 20 of the alteration switch 7 is connected to a terminal 21 and a terminal 23 is also connected to a terminal 24. Since magnetic heads 3, 4 and 5, 6 are selectively connected to the primary windings 26, 27 of the rotary transformer by the alteration switch, the rotary head device may be satisfied by two pairs of windings of the rotary transformers.

Inventor: SUGIMOTO YUJI
IPC: B65H1/26
Filed: 1989-05-15
Abstract: PURPOSE:To prevent position deflection of a rotary plate and avoid discharge of a paper with a position deflection for a paper supply action performed after carry-up rotation of a rotary plate by providing universal joints for supporting the rotary plate to be freely rotatable at least in two directions about a point of an angular part between non-supply sides.

IPC: G01N29/04
Filed: 1978-10-03
Abstract: PURPOSE: To secure the recording featuring an easy-to-see defective position by controlling the position of the recording needle in accordance with the rotary position and speed of the roll for tracing of the flaw detection locus recorded on the  recording paper and then recording the defect via the ultrasonic probe which has  the shift of a fixed speed in the roll axle direction.  
     CONSTITUTION: Roll 1 receives the spiral scanning by ultrasonic probe 8 which shifts along the outer circumference of rotating roll 1 and in parallel to the axle of roll 1. With turn of roll 1 every fixed angle, rotary position detector 5 generates pulses. And pulse generator 4 generates pulses in the cycle according to the rotary speed of roll 1. These pulse raws are processed at signal process circuit 12, and pulse distributor 14 generates the orthogonal double coordinate pulse signal corresponding to the flaw detection locus to control the position of the recording needle. The recording needle traces flaw detection locus 19 recorded on recording paper 17 which has the synchronous shift with probe 8 to record the defect on locus 19 via the discharge and the like caused by the defect signal or the like which passed through probe 8. As a result, the defect recording is ensured, in which the defective position can be detected at a glance.

Title: Shutter device for camera
Inventor: KOBAYASHI KOICHI
IPC: G03B9/10
Filed: 1995-05-19
Abstract: PURPOSE: To independently control an F value and to secure high-speed responsiveness by driving two kinds of blades by using a single motor as a driving source. CONSTITUTION: An aperture driving member 18 interlocked with the aperture blade 21 is previously arranged at a fully closed position and a closeout driving member 23 interlocked with a closeout blade 26 is previously arranged at a fully opened position. In a process that a driving member 3 is made to travel by the motor 2, the blade 26 is converged by a cam edge 3g. When a magnet 28 is excited in the midst of the converging action, the converging action of the blade 26 is stopped and the F value is controlled. When an aperture driving lever 18 is released from a releasing point 3e, the blade 21 is actuated to be opened by a spring release action. However, the F value is regulated by the blade 26.  When the magnet 28 is demagnetized at a desired time, the blade 26 is spring-released toward the fully closed position from the regulating position of the F value and an exposure action is finished. Then, the exposure time and the F value are independently controlled by the single motor and the high responsiveness of both actions are achieved by the spring release action.

Abstract: PURPOSE:To manufacture an epitaxial wafer at a low cost, by diffusing an embedded diffused layer from the surface of a substrate, diffusing an embedded isolation layer into the entire surface of the substrate, growing an epitaxial layer on the substrate, and thereafter diffusing a surface isolation layer. CONSTITUTION:An n-type diffused layer 20 is diffused in a p-type substrate 10. Then, a p-type embedded isolation layer 30 is diffused in the entire surface of the substrate 10. Then, an n-type epitaxial layer 40 is grown on the substrate 10, in which the layer 20 and the layer 30 are diffused. Then, a frame shaped surface isolation layer 50 is deeply diffused in a (p) type so as to surround a partial region 41 of the layer 40. At this time, an impurity diffused part 30a is yielded from the layer 30 so that the part 30a is directed toward the surface of the layer 40 at the time of heat treatment. The layer 50 and the layer 30 are conductively connected. In this way, a material having an especially high concentration is not required for the substrate 10. Only a single photo-processing for impurity diffusion into the substrate 10 is sufficient.

Abstract: PURPOSE:To prevent the deterioration of an image quality such as an image blur, etc., by setting a home position of a developing device so that a photosensitive drum is positioned between a first developing unit and a second developing unit. CONSTITUTION:A developing device 100 for loading developing units 101M, 101C, 101Y and 101B and moving in the left and the right directions, a transfer device 5, a pre-destaticizer 6 for executing easily cleaning, and a cleaning device 7 are placed, respectively. In this case, a home position of the developing device is set so that a photosensitive drum 1 is positioned between the magenta developing unit 101M of first development and the cyan developing unit 101C of second development, therefore, it does not occur that a developing sleeve 102 and a bumping roller 103 are positioned right under the photosensitive drum 1 at the time of stopping the main body. Therefore, at the time of attaching and detaching the photosensitive drum and the developing unit for the maintenance, etc., it does not occur that the photosensitive drum and the developing sleeve placed adjacently to each other are damaged mutually by the attaching/ detaching operation. In such a way, deterioration of an image quality can be prevented.

Title: Work transfer device
Inventor: MORISHIMA SHINJI
IPC: B23Q3/06
Filed: 1991-03-29
Abstract: PURPOSE:To center a work with a simple mechanism and then transfer the work efficiently by providing an arm with an engagement surface which is formed in an arc shape contacting an outer periphery of the work so that it is slightly eccentrical from the center of the work. CONSTITUTION:When a slide cylinder 5 is positioned at a measurement station, a lower arm 9 catches a work 2 on an engagement surface if the work 2 is transferred by a carrier base 3. At this time, mounting position of the arm is so determined that the center of the work 2 agrees with a rotary spindle of a dynamic balance measuring device. Also when a rotary actuator 6 is operated, arms 9 and 10 rotate and are inverted to the opposite side of the work 2 and hence up/down position relationship between the arms 9 and 10 is inverted. Since the center of the rotary shaft of the actuator 6 is slightly eccentric from the center of the work 2, a proper space is produced between the arm and the work by inverting the arms 9 and 10, thus preventing the work 2 from contacting the arm at the time of measurement.
