Title: Method and device for cleaning magnetic tape
Inventor: HIRAI SATORU
IPC: G11B23/50
Filed: 1993-03-19
Abstract: PURPOSE:To suppress drop-out generation caused by ground powder by sweeping out the ground powder generated at the time of cleaning with a non-woven fabric tape by cleaning a magnetic tape while always sliding the non-woven fabric tape behind a grinding tape. CONSTITUTION:Non-woven fabric tape guides 8 and 9 are arranged while sandwiching a guide 6 for grinding tape from forward and backward sides. When cleaning a magnetic tape 4 by reciprocatively sliding it, a non-woven fabric tape 10 or 11 is always slid after a grinding tape 7 is slid. Therefore, the ground powder generated when grinding the surface of a magnetic layer with the grinding tape 7 is swept out by the non-woven fabric tape 10 or 11 to be slid behind the grinding tape 7. Accordingly, even when the ground powder is generated by sliding with the grinding tape at the time of cleaning, it is always swept out by the non-woven fabric tape, the magnetic surface of the magnetic tape 4 is precisely cleaned, the dropout generation caused by the ground powder is sufficiently suppressed, and no adverse influence is exerted upon the electromagnetic converting characteristic of the magnetic tape.

Abstract: PURPOSE: To increase the modulation speed by shaping the distribution of intensity of diffracted light to the angle of incident light in a rectangular form, by forming the electrodes of electro-acoustic transducer so that the width of electrodes may vary along the light transmission direction.  
     CONSTITUTION: An electro-acoustic transducer 2 made of piezo-electric crystal plate such as lithium niobate crystal is adhered on an acousto-optical medium 1, and the contour of electrodes 6a to 6c on the upper surface thereof is formed in sinx function. And an electrode 7 on the lower surface is divided and lead wires are connected so that the phase of the voltage applied to the electrode 6b may be inverted with respect to that of the voltage applied to adjoining electrodes 6a to 6c. As a result, the distribution of excitation of sound wave due to the electro-acoustic transducer 2 is formed in sinx/x function, so that the angular characteristic of diffracted light 4 transmitted beneath the central axis of the elctrode pattern and diffracted by sound wave may have a rectangular form. Therefore, by confining the incident light 3, the modulation speed may be accelerated.

Title: Typeprinter
Inventor: YANAGIURA TAKASHI
IPC: G06K15/00
Filed: 1980-06-24
Abstract: PURPOSE: To facilitate the handling of a typeprinter, by detecting the position of a guide for a loaded blank sheet, storing the position information on the loaded blank sheet in a memory, and controlling a typeprinting operation onto the loaded blank sheet on the basis of the position information.  
     CONSTITUTION: A controller further shifts a carriage 5 rightwards by one character (one column) and adds +1 to a register R1, to recognize the width of a loaded blank sheet. After the controller raises the content of the register R1 by +1, the controller recognizes the existence or absence of the blank sheet through an interface. If there is the blank sheet, the controller shifts the carriage 5 by one character and controls to add +1 to the register R1. Thus, the existence or a absence of the blank sheet is recognized, whenever the carriage 5 is shifted by every one character. When the blank sheet is used up, the controller sets a value, which is produced by addition of a datum corresponding to a distance between a typeprinting head and a sensor to the register R1, into a register R3, and completes the control.

Title: Decoder circuit
Inventor: ISHIZAKI OSAMU
IPC: H03M7/00
Filed: 1989-04-05
Abstract: PURPOSE:To quicken signal transmission and to reduce power consumption by constituting a decoder circuit with one transfer gate and one N-channel transistor(TR) so as to decrease the number of TRs thereby reducing the gate capacity to be driven by one signal. CONSTITUTION:For example, when address signal lines 1a, 1b are at an H level, address signal lines inverse of 2a, 2b in complementary relation to the address signal lines 1a, 1b sending always the signal of inverted level of the lines 1a, 1b go to L level. Then when the address signal lines 1a, 1b are at an H level, only the activated signal line 11d goes to an H level and other activated signal lines 11a, 11b, 11c go to L level. Similarly, when the address signal lines 1a, 1b are at H and L level respectively, only the activated signal line 11b goes to an H level. Thus, the gate capacity to be driven by the signal is decreased, the signal is sent at a high speed and the power consumption is reduced.

Title: Planetary gear
Inventor: ICHIOKA EIJI
IPC: F16H1/46
Filed: 1994-04-25
Abstract: PURPOSE:To eliminate thrust force occurring in compound planet gears so as to obtain always a good intermeshing state by providing mutual eequivalence in twist directions of respective intermeshing teeth and leads of large diameter and small diameter pinions. CONSTITUTION:In each planetary gear 10, a sun gear 14 is disposed concentrically with the center line, and it is spline fitted to a motor shaft 12, and its position in axial direction is then regulated by a carrier 16 through thrust bearings 30, 32. A large diameter pinion 26 intermeshes to the sun gear 14, and a small diameter pinion 28 intermeshes to a ring gear 24. In this case, both pinions 26, 28 are left twisted in their intermeshing teeth and are some mutually same in leads. Accordingly, plural compound planet gears 20 are able to move independently in their axial directions. And thus, proper intermeshing state can be easily obtained, and also thrust forces occurring in the pinions 26, 28 due to the twist of intermeshing teeth are mutually opposite in orientation and are similar in their magnitudes. So, overall thrust force in the compound planet gears 20 becomes almost 'zero' and thus load in the carrier 16 is reduced.
