Abstract: PURPOSE:To lessen extremely an irregularity in the line characteristic impedance of a balun transformer by a method wherein a plurality of pieces of winding guides are arranged at least on the outward side of a balun transformer core in such a way that the intervals between winding conductors are roughly made even. CONSTITUTION:A plurality of pieces of slits 4 are formed in the outside dual- hole balun transformer core 31 at equal intervals as winding guides and a winding 22 consisting of a single wire is wound on these slits 4. These slits 4 may be provided only at external angles arranged evenly in the outside. Moreover, an a little larger dual-hole balun transformer core 32 is used, slits 41, which are used as winding guides, are formed also in the two inside parts of the core 32 and conductors of the inside parts are also made uniform. Thereby, a balun transformer having little irregularity in its line characteristic impedance can be obtained.

IPC: F16H1/14
Filed: 1979-09-05
Abstract: PURPOSE: To easily discover a fault location in a device, by only operating its drive source and a gear speed changer at an optional time other than a case of emergency.  
     CONSTITUTION: When a pump is not operated, a shifter 20 is raised through a cylinder 21 after stopping an engine to cease the rotating motion of an input shaft 3. As said shifter 20 is raised an internal gear 17 is similarly raised, and this causes inner teeth 18 of said internal gear 17 to be easily disengaged from outer teeth 9 of a gear coupling 8 at the drive side. When the pump is operated, a gear coupling 14 at the driven side is rotated through a phase aligning mechanism 22 and synchronized with the gear coupling 8 at the drive side and then the shifter 20 is lowered to integrally couple outer teeth 15 and 9 through the internal gear 17.

Title: Automatic paper sheet feeding device
Inventor: TAKAYAMA HAJIME
IPC: B65H3/52
Filed: 1989-05-02
Abstract: PURPOSE:To prevent double feed of paper sheets certainly by furnishing a spring to energize an arm so that a separator roller rotates in the opposite direction to sheet feed, and providing a stopper to hinder rotation of this arm so that the separator roller is restricted from rotation in the sheet feeding direction. CONSTITUTION:While a first original text sheet is being fed, a separator roller 11 is at a standstill in a place where an arm 13 is in contact with a stopper 17, and a tensile force due to a spring 14 is applied to this arm 13. While the first original is being fed, the second original and even thereafter may be fed to between an aux. feed roller 10 and a separator roller 11 because of poor separating motion of a separator piece 6. Because friction force between the first and second originals is small, the transport force applied by a feed roller 5 to the second original is small, to allow the tensile force of the spring 14 to rotate the separator roller 11 in the direction opposite to the sheet feeding, which pushes back the second original and thereafter eventually to accomplish prevention of double feed of sheets.

IPC: H04M1/65
Filed: 1987-05-12
Abstract: PURPOSE:To make it possible to hear a message recorded for purpose of automatic answering easily from a nearby telephone set from outing destination by instructing the reproduction output of a voice message recorded with combinations of word voice for purpose of automatic answering. CONSTITUTION:A voice inputted through a incoming telephone line, is recognized by a speech recognition part 9. In case a recognized voice word is recognized to be a word preliminarily set in dictionaries 10a-10c and has been given in a preliminarily set order, the voice is decided to be an instruction for the reproduction of a message recorded for automatic answering uttered by the user. And when this reproduction-instruction is confirmed to be correct one, the voice message recorded for automatic answering is reproduced and outputted to the telephone line from which the instruction comes. Thus a reproduction- instruction can be given vocally, therefore, it can be irrespective of the kinds of telephone sets, hence any kind of nearby telephone set can be used to reproduce and hear the prerecorded message.
