Abstract: PURPOSE: To improve durability and workability by fitting transducers at positions on the side faces of a board within the specified multiple of the wavelength of a surface acoustic wave(SAW) to be propagated from the board surface of the device in the direction of thickness. CONSTITUTION: On the side faces of a board 10, an X side transmitting transducer 11, X side receiving transducer 12, Y side receiving transducer 13 and Y side transmitting transducer 14 are fitted at the board side face positions within the double wavelength of the SAW to be propagated from the board surface in the thickness-wise direction.

Title: Magnetic head
Inventor: ISHIJIMA NORIO
IPC: G11B5/53
Filed: 1982-07-23
Abstract: PURPOSE:To facilitate an easy production and to have easily an azimuth for a magnetic head, by forming a closed magnetic path circuit of a magnetic metallic thin film having a front gap part on a monolithic substrate containing a through hole at its center part. CONSTITUTION:The substrate 2 of a magnetic head is monolithic itself and contains a through hole 21 for winding at the center part. The thickness of the substrae 2 is reduced at the areas between the hole 21 and recess parts 28 and 29 respectively in comparison with other areas. Thus, the output is improved and the noises generated from an external system are reduced. A closed magnetic path circuit 3 of a magnetic thin metallic film 3 is formed on the substrate 2. The film 3 is coated evenly over the substrate 2 so as to form a front gap part 4 at the front part of the substrate from the ridgeline of the front edge surface through the hole 21. The direction 1 of the edge surface of a thin film forming the gap part 4 is tilted by a prescribed angle alpha to the normal line direction (n) on the rear side of the thin film forming surface of the substrate 2. Thus an azimuth is given to the part 4. For this purpose, the part 4 is formed by using a parallel flat plate for the substrate 2 and then grinding the substrate 2 in the direction having an inclination alpha.

Title: Sheet feeder and automatic document feeder having the sheet feeder and image forming device
Inventor: NARUSE HARUO
IPC: B65H3/06
Filed: 1994-05-18
Abstract: PURPOSE:To secure the separating-carrying operation of a separating-carrying part composed of carrier rollers to rotate in the sheet carrying direction and separating rollers to rotate in the return direction. CONSTITUTION:A sheet D is separated and carried by carrier rollers 3 to rotate in the sheet carrying direction and first and second separating rollers. The first separating roller 13 is set almost in the same with a friction coefficient of the carrier rollers 3, and the second separating roller 12a is set smaller than a friction coefficient of the first separating roller 13. Thereby, though the first separating roller 13 and the carrier rollers 3 are formed of a material having almost the same friction coefficient, carrying force of the carrier rollers 3 can be made larger than carrying force of the first and the second separating rollers, and the sheet can be reliably separated and carried, and selectivity of a construction material of the carrier rollers 3 and the first separating roller 13 can be widened.

Filed: 1987-05-28
Abstract: PURPOSE:To make the title core to be used effectively in a pulse compressor by a method wherein a core where a Co-related amorphous alloy thin material whose magnetostriction is positive and an electrically insulating film have been laminated or wound alternately is installed in order to increase a squareness ratio, to reduce an iron loss and to reduce a rise in temperature of the core. CONSTITUTION:This core is constituted in such a way that a Co-related amorphous alloy thin material whose magnetostriction is positive and an electrically insulating film are laminated or wound alternately. As an alloy for this purpose the alloy which is expressed by the following general formula can be enumerated: (Co1-xFex)100-z (Si1-yBy)z, where 0.05<=x<=0.5, 0.3<=y<=0.9 and 15<=z<=27. The magnetostriction influences a squareness ratio of the alloy; if the magnetostriction is positive, the squareness ratio of the core is increased. This kind of thin material can be prepared easily if a molten-metal quenching method is applied to the alloy of a prescribed composition. As a result, the squareness ratio can be increased; an iron loss can be reduced rise in temperature can be reduced, and when this core is incorporated in a pulse compressor, it is effective.

Abstract: PURPOSE:To decrease the number of mechanical operations of a sound repeater of an aural writing recorder, by using a static storage for sound repetition in order to simplify the operation and to eliminate the loss time due to a rewinding action. CONSTITUTION:The reproduced signal of a tape recorder 2 is delivered through a speaker 7 in the form of a voice and at the same time converted by an A/D converter ADC8 to be written to a memory 10. The memory 10 always stores the latest data equivalent to a prescribed past period. The output of a voltage dividing circuit 11 is converted by an ADC13, and the signal which read out an ROM14 with the output of the circuit 11 is turned into subtracted address value L. A typist controls the output value L of the ROM14 by means of a lever 4. The value L equals to the rewound degree of the recorder 2. The recorder 2 is stopped with a push of a switch 5, and the writing is discontinued. The contents of the memory 10 of an address region between addresses A and B are read out repetitively by applying the subtraction value B=A-L (A and L set at a stop point) to a start address. The read-out contents of the memory 10 are converted by a D/A converter DAC17, and the voices are delivered repetitively via a switch 6.
