Title: Switch mechanism
Inventor: KIMURA HIROYUKI
IPC: G03B17/42
Filed: 1981-03-11
Abstract: PURPOSE:To realize the convenience for snapping in an emergency or the photographing just for a specific number of frames, by carrying out the switching from the continuous winding mode to the rewinding mode at an optional position in addition to the automatic switching which is carried out when the continuous winding is over. CONSTITUTION:A film is continuously wound from a film container to a spool chamber prior to photographing, and then the photographing is carried out while rewinding the film to the film container by a frame. With such a motor-driven camera, a continuous winding end detecting means detects the change of torque when the continuous winding is over and moves a torque detecting lever 78 on a patrone detecting lever 76. As a result, the automatic switching is possible by a switching contact bar 79 between the winding mode and the rewinding mode. In case the continuous winding is discontinued at a point when a specific number of frames is wound, a push-button 82 is pushed to move the lever 78 to the left side to perform the switching.

Abstract: PURPOSE: To surely compact a ground through percussion in a small head and a high cycle down to a prescribed depth omnidirectionally, in not only the surface of a road disintegrated and loosened by a natural disaster but also in an intermediate layer and a deeper layer. CONSTITUTION: A heavy construction machine 7' is brought in a work site and a weight 8' provided with a frame 9, so as to be vertically movable is lifted by a prescribed stroke to impart a percussional force to a huge foot body by the potentional energy or the additional kinetic energy imparted by a forcible lowering force. Since the huge foot body is set to follow an uneven part 3" of the surface, the striking force is omnidirectionally transmitted to a sufficient depth in the upper layer part 1" of the ground 1 to prevent the ground from getting loose or so via a loading weight. Sufficient compaction can be surely carried out to obtain sure strength and rigidity, even if the ground is composed of sand and gravel layer or a debris layer. In this way, the ground can be surely compacted in a small head and a high cycle with respect to insufficient strength and rigidity in the ground down to the intermediate and deep layers.

Abstract: PURPOSE:To reduce the lamination count of inner electrodes without lowering a surge-resistant amount by a method wherein end edges of the inner electrodes are exposed at whole outer-circumference side faces and the end edge parts of the inner electrodes excluding the end edge part connected to a first outer electrode or a second outer electrode are covered with an insulating material. CONSTITUTION:End edges of a plurality of inner electrodes 2 to 5 are formed so as to be exposed at whole outer-circumference side faces of a sintered body 1. Remaining end edge parts of outer electrodes 9a, 9b excluding the end edge part connected to the first outer electrode or the second outer electrode 9a, 9b are covered with an insulating material. That is to say, when the sintered body 1 is observed in the thickness direction, the inner electrodes 2 to 5 are formed in a size covering the whole plane region of the sintered body 1. Consequently, the area per layer of the inner electrodes 2 to 5 can be expanded, and a surge-resistant amount per layer can be increased. Thereby, the lamination of the inner electrodes 2 to 5 can be reduced without lowering the surge-resistant amount.

Abstract: PURPOSE: To prevent the semiconductor-element characteristics from worsening due to the α-ray irradiation by providing a package with a projecting part in the direction of shielding a sealing material and a semiconductor element.  
     CONSTITUTION: On the body 1 of a ceramic package for an element, a semiconductor element 2 is set and bonded.

Title: Servo controller for scanner of image forming device
Inventor: OKADA NORIKAZU
IPC: H02P7/29
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To prevent an adverse effect due to the offset value of a current sensor to the control accuracy of a motor by correcting the offset voltage value of the current sensor as the center value of the target designation voltage of the motor speed when the power supply of an image forming device is turned on. SOLUTION: The power supply of an image forming device is turned on, and the detection output of a Hall current detector 40 is converted into the voltage value proportional to the motor current and inputted to a microcomputer 30 via an A/D converter 50. This voltage value means the output valve that is detected when the motor drive is stopped, and zero V is ideal. In fact, however, the detector 40 has an offset and accordingly a recognition means contained in the microcomputer 30 calculates the offset voltage value as 'actual output value of motor stop mode - ideal output value of motor stop mode = offset voltage value'. This offset voltage value is added to the target designation voltage that is accordant with the target designation current calculated on the basis of the non-offset voltage, and the offset voltage value of a current sensor is corrected.

After the ceramic layer 3 is dried, conductive paste is jetted from a functional material paste jet head by the ink jet method and thereby a conductive film 6 as an internal circuit element is formed on each ceramic layer 3. After the conductive film 6 is dried, subsequently, the ceramic slurry 9 is jetted from the ceramic slurry jet head 2 by the ink jet method and thereby a ceramic layer 10 is formed on the ceramic layer 3 whereon the conductive film 6 is formed. A laminated type ceramic electronic component is obtained by repeating the same process in a desired number of times.

Abstract: PURPOSE:To provide a stably fixed picture, which corresponds to an original density, by detecting the temperature of a heating body and the original density, and adjusting the temperature of the heating body according to the detected original density. CONSTITUTION:The density is detected by means of a sensor 18 for detecting an original density, by receiving the reflected light of an original, which is irradiated with an original illuminating lamp, with a photodiode; and the density is fetched in a MPU 19. The setting temperature value of the heating body 12, which corresponds to the detected density, is stored in a memory 20, and the MPU 19 gives a pulse driving signal to the heating body 12 under a temperature value corresponding to the original density. That is, the control temperature of the heating body 12 is set high when the detected original density is high, and the temperature value is set low when the original density is low. Thus, a stably fixed picture is supplied even when the original has a high density, and the consumption of power is restrained when the original has a low density.

Abstract: PURPOSE:To improve reliability by performing a phase comparison with a leading edge or a trailing edge of a binarized regenerative signal and generating a synchronous clock for detecting the regenerative signal synchronized with the leading edge or the trailing edge. CONSTITUTION:The synchronous clock (c) in synchronization with the leading edge is obtained by a PLL circuit 2 for performing the phase comparison of the leading edge of the regenerative signal (b). Thus, the clock having a period of 0.5 times as much as a edge shift amt. is obtained. Then, by utilizing the clock (c), the signal (b) is latched in using a D-FF 3, and a latch signal (d) having one period of the synchronous clock as equivanent to the edge shift amt. is obtained. Then, a shift register output (e) delayed by one period of the clock (c) is obtained by a one-bit shift register 4 fromthe signal (d). By logically multiplying this output (e) and the signal (d) with an AND circuit 5, the edge shift amt. is offset, and a reproducing data (f) is obtained to be faithful to the recording signal. By this method, an error rate in reproducing data can be improved.
