Title: Image forming device
Inventor: TAKAMURA HIDEKAZU
IPC: G03G15/20
Filed: 1990-03-13
Abstract: PURPOSE:To keep damage when paper jamming occurs to the minimum by providing a control means for a spring clutch which is set so that the transmission of driving force to a fixing roller is stopped at the time of detecting the paper jamming. CONSTITUTION:When the paper jamming is detected by a paper jamming detec tion means 27, the control means 18 for the spring clutches 13 and 14 extends the interior diameter of the spring 13 which constitutes the spring clutches 13 and 14, and the driving force from a driving source is not transmitted to the fixing roller 28, which is stopped. On the other hand, when the state of the paper jamming is released, the control means 18 for the spring clutches 13 and 14 restores the interior diameter of the spring 13 which constitutes the spring clutches 13 and 14 to an original one and the driving force from the driving source is transmitted to the fixing roller 28, which is rotated. A lubricant holding and supplying means 16 supplies lubricant to the locking surface 13A of the spring 13 which constitutes the spring clutches 13 and 14, so that the driving force is transmitted without the burning of the spring 13. Thus, the action of a fixing device is immediately stopped when the paper jamming occurs and the damage is kept to the minimum.

Abstract: PURPOSE:To improve stability on the surface of a slope and make a contribution to the preventive maintenance of natural environment by packing a wire-cylinder with stuffing stone made of a concrete lump of the same shape formed into an aspherical body such as an elliptical body. CONSTITUTION:Concrete is placed in a form 13 made of a lower form 14 and upper forms 15 and 15, thereby preparing a wire-cylinder stuffing stone 12 made of an aspherical concrete lump such as an elliptical body. Thereafter, a cage is packed with a plurality of pieces of the stuffing stone 12 of the same shape so produced and a wire-cylinder is thereby manufactured. As a result, the mass production of the stuffing stone 12 can be realized, and the stable supply thereof as well as the reduction of cost related to labor can be attained. Also, as no rubble stone is used, natural environment is not injured. In addition, the shape of the stone 12 is uniform and, therefore, void space in the wire- cylinder is reduced, thereby improving stability on the surface of a slope.

Abstract: PURPOSE:To generate two-dimensional vibrations by distortion in the thickness direction and surface direction of a piezoelectric element by carrying the piezoelectric element so that the surface of the piezoelectric element is formed in an orthogonal surface to an axis in the longitudinal direction of a vibrator. CONSTITUTION:A piezoelectric element plate group 3 between the large sectional sections 1a and 1b of a vibrator 1 consisting of a cylindrical elastic body is composed of piezoelectric element plates for A phase and piezoelectric element plates for B phase. When voltage mutually having phase difference at approximately 90 deg. is applied at that time, an elliptic motion in an x-z plane is generated in the spring section 1e of the front end of the vibrator 1 by synthesizing generated vibrations, a rail 2 and the spring section 1e of the vibrator 1 are brought into contact intermittently, and either of the rail 2 or the spring section 1e is moved in the (x) direction. The small sectional section 1d of the vibrator 1 has an effect, in which natural frequency is lowered and internal loss is reduced. The natural frequency of the spring section 1e is made sufficiently higher than excitation frequency to the vibrator 1, and the spring section 1e follows up vibrations.

Abstract: PURPOSE:To enable a check device to surely and quickly detect the mounting position of an electronic part independent of its size by a method wherein a slit pattern is made to change in pitch corresponding to the size of the electronic component. CONSTITUTION:When a small electronic component 10a is mounted on a check area, a slit pattern S is formed narrow in pitch.

The computer device 5 judges that the electronic components 10a are good in mounting state or not. When a large electronic component is mounted on the check area, a slit patter S is formed large in pitch. When a large electronic component 10a and a small electronic component 10a are mixedly mounted on the check area, a slit pattern S is set large in pitch in a region where a large electronic component 10a is mounted and small in pitch in a region where a small electronic component 10a is mounted.

Title: Speaker
Inventor: KITOU ISAO

Filed: 1980-05-09
Abstract: PURPOSE:To obtain a dynamic speaker having a plane diaphragm of a wide band and high performance, by improving the structure of the plane diaphragm and thus increasing the limit of a piston oscillation region. CONSTITUTION:A plane diaphragm 10' is a composite diaphragm in which the skins 14 and 15 made of the aluminum alloy of 20mu thickness are stuck on both surfaces of a core 13 made of the foamed acrylic material having 3mm. thickness. The skin 14 on the surface contains plural linear rolls 16 extending radially from the axial center; while one or plural concentric corrugations 17 are provided concentrically with the plane diaphragm to the skin 15 on the rear surface, respectively. The flexural rigidity is increased in both directions of diameter and circumference by these rollers 16 and corrugations 17. Thus the occurrence can be reduced for many oscillation modes. As the surface density of the diaphragm has virtually no change, the ratio of the flexural rigidity/surface density is increased. As a result, the high-band resonance frequency that causes a divided oscillation is increased.
