Title: Magnetic electroacoustic transducer
Inventor: NORO MASAO
IPC: H04R3/04
Filed: 1982-10-12
Abstract: PURPOSE:To attain an electroacoustic transducer having a linear relation between a voice coil current and a voice coil drive force by providing a detecting coil crossing magnetic flux penetrating the side surface of the voice coil to the voice coil and obtaining the change in the magnetic flux relating directly to the drive of the voice coil from a detecting coil. CONSTITUTION:An auxiliary coil 8 is provided in a magnetic circuit to change magnetic flux density. That is, an audio signal obtained from a signal source is amplified at a power amplifier 10, applied to the voice coil 6, an output of the detecting coil 6 is applied to the auxiliary coil 8 wound on a center pole 2 via said integrator 11 and a coil drive amplifier 12. The magnetic flux generated from the auxiliary coil 8 and that generated from the voice coil 6 are of an opposite direction and then, the magnetic flux generated from the voice coil 6 is controlled for negative feedback. Thus, since the magnetic flux density is kept constant at all times, no distortion exists and the symmetry for both polarities is attained.

Abstract: PURPOSE:To realize a good electric connection and realize the flat filling of a hole after an epitaxial growth, by making the foregoing manufacture include the process for boring the hole in an ohmic-electrode forming part and the process for performing in this hole the epitaxial growth of a crystal having a low resistance. CONSTITUTION:When a crystal is made to grow selectively in a hole bored in a semiconductor substrate 1 or in a semiconductor crystal growth layer, the end part of a selective growth layer 5 and the side surface of the hole are joined to each other at a crystal level. That is, the foregoing manufacture is made to include the following first and second processes. The first process is the process for boring in an ohmic- electrode forming part the hole which has a rectangular opening and whose side and bottom surfaces have equally an equivalent Miller index to the Miller index of an electron feeding layer. The second process is the process for performing in this hole the epitaxial growth of a crystal having a low resistance. Alternatively, the method for forming a mask 4 having an opening in the hole part present on the electron feeding layer can be used too. In this manner, a parasitic resistance present in the connection part of an electron transit layer with the ohmic electrode can be reduced.

Title: Line abnormality detection system
Inventor: SHIMIZU TAKEO
IPC: H04L69/40
Filed: 1988-07-19
Abstract: PURPOSE:To detect the line abnormality of transmission/reception line with one side of an equipment only by comparing a sent tag with a receiver side tag while a tag of a received data is sent additionally. CONSTITUTION:A code (BCC) representing the normality of data and an incremented data (n) are added to the transmission data from an equipment C16 and the result is sent. A reception state monitoring section 23 uses the BCC so as to reset the counter, thereby detecting the line abnormality of the reception line. A transmission circuit 19 adds an increment data (n) stored in a reception tag storage section 25 and sends the result and a reception state monitoring section 22 uses the BCC to reset the counter, thereby detecting the line abnormality of the reception line. Then the increment data sent by the transmission state monitoring section 24 and the received increment data are compared and when the data is equal to each other, it is discriminated that the transmission line is normal and when they differ from each other, it is detected to be abnormal. Thus, the abnormality of the transmission/ reception line is detected by one side of equipment only.

Title: Developing device
Inventor: KOROKU SHOICHI
IPC: G03G15/08
Filed: 1986-07-30
Abstract: PURPOSE:To improve detection accuracy by permitting a cleaning member to clean a developer detecting surface when a developer level lowers near to the developer detecting surface. CONSTITUTION:The bottom end of the cleaning member 7 is disengaged from a crank part 4b of an agitating bar 4 and only the agitating bar 4 rotates clockwise from the point beta after the bottom end of the cleaning member 7 arrives at the point beta. Vanes 8 move from the left toward the right together with the cleaning member 7 in this case; therefore, the detecting surface 6 of a level sensor is rubbed by the cleaning member 7. The developer in front of the detecting surface 6 of the level sensor is scraped by said vanes 8 and a space is generated in front of the detecting surface 6 of the level sensor but there is still a substantially large amt. of the developer in a developing device body 1; therefore, the collapsion of the developer arises right after the passage of the vanes 8 in the space and the space is annihilated. The generation of a wrong detection output in the level sensor is thus obviated.

Filed: 1985-08-14
Abstract: PURPOSE:To make possible to accurately adjust the speed over a wide range, and to simplify the arrangement of a speed designating type stepless speed change gear, by adjusting the degree of slipping between an input disc and an output disc to carry out stepless speed change. CONSTITUTION:Since a gear 3 is connected with an output disc 4 by means of a screw, the gear 3 may be axially moved to be pressed against an input disc 5 so that it rotates in the same direction as that of the input disc 5. The gear 3 is rotated by means of a speed designating shaft 1, and therefore, the output rotational speed may be obtained in proportion to the rotation speed of the speed designating shaft 1. The difference between the output rotational speed and the input rotational speed may be absorbed by the slipping between the output disc 4 and the input disc 5.
