IPC: H04N5/93
Filed: 1984-04-12
Abstract: PURPOSE:To reduce a noise generated at a portion of a low level by inserting a variable band pass filter controlled so as to have a narrow pass band as an amplitude level of an input FM signal is small into a pre-stage of an FM demodulator. CONSTITUTION:A synthesis signal reproduced by rotary magnetic heads 1A, 1B from a magnetic tape 2 is fed to a high pass filter 4 via a preamplifier 3 and a modulation luminance signal YFM is extracted. The signal YFM is fed to an inverting input terminal of a limiter 5. An output of the limiter 5 is connected to a low pass filter 6 and a high pass filter 7, the both constitute a variable band pass filter 8 and a positive feedback path is constituted of a series circuit comprising the filters 6, 7. When the amplitude level of the YFM applied to the filter 8 is small, the gain of the limiter 5 is large, and when the amplitude level is large, the limiter 5 is saturated, the amount of feedback is reduced and the filter characteristic is made flat. The YFM passing through the filter 8 is fed to an FM demodulator 10 via a limiter 9 and a luminance signal Y is obtained.

Title: Piezoelectric actuator
Inventor: INOUE JIRO
IPC: H01L41/09
Filed: 1990-03-23
Abstract: PURPOSE:To obtain a large amount of displacement even within an adverse electric field by allowing one piezoelectric plate to consist of one piezoelectric ceramic body which is polarized in thickness direction and by allowing a plurality of piezoelectric ceramic pieces to be connected in parallel through an electrode for the other piezoelectric body. CONSTITUTION:A piezoelectric plate 2 consists, of a number of small strip shaped piezoelectric ceramic pieces 21 which are joined through electrodes 22a, 22b.... Polarization of each piezoelectric ceramic piece 21,... is aligned in joining direction (direction shown by an arrow (a) in the figure) and polarization of adjacent piezoelectric ceramic pieces is reversed each other. A piezoelectric plate 3 consists of polarized one piezoelectric ceramic plate which is polarized in thickness direction and is applied to a shim 1 so that the polarization direction is vertical to that of the above piezoelectric plate 2. When a DC voltage is applied between terminals t1 and t2, an area of entire piezoelectric body 2 is increased, thus enabling a shim 1 to be flexed and deformed downward. Since the piezoelectric plate 3 oscillates in area vibration mode, drive force for flexing and deforming the shim 1 increases and the amount of displacement of the shim 1 also becomes larger along with it.

Abstract: PURPOSE:To reduce the speed of contamination for an ion discharger, by providing an earth conductive member on the top face of a both-end part insulator block of a shielding member in a corona discharger and accordingly dispersing uniformly the inflow of the outside air due to the blow-out of the ion wind. CONSTITUTION:A conductive member 19 connected to the earth is provided to the top part of a both-end insulator block 11 of a U-shaped shielding member 10 of a corona discharger C containing a corona wire 12. Thus the blow-out of an ion wind I is promoted at the aperture part of the discharger C and dispersed uniformly. Accordingly the inflow (a) caused by the above-mentioned blow-out is also dispersed uniformly to eliminate a sudden inflow. As a result, the speed of contamination due to the mixture of foreign matters is reduced to the wire 12 or the shielding inner wall. Thus a stable corona discharger having the reduced number of times of cleaning is obtained for an electronic copying machine with a simple constitution.

Title: Gas drying apparatus
Inventor: BINSENTO PII FURETSUSHIYU
IPC: B01D53/26
Filed: 1988-03-28
Abstract: PURPOSE: To remarkably decrease the quantity of the dry air required for regeneration by alternately opening and closing a purge valve to alternately pressurize and evacuating the columns under regeneration of a desiccating agent during regeneration and limiting the quantity of the air released from the purge valve. CONSTITUTION: While the column 12 is under a drying cycle, the valve 16 is opened and the valve 18 is closed and the satd. air from an inlet 200 is supplied from the valve 16 to the column 12, where the moisture in the satd. air is absorbed by the desiccating agent. The pressurized desiccating agent is delivered from an outlet 28 through a pipe 24 and a check valve 26. The dry air is partly branched to a pipe 34 and is sent downward in the column 14 through a joint 38, a check valve 42 and a pipe 30. The purge valve 50 is intermittently opened and closed during the regeneration cycle. The pressurization and evacuation are repetitively applied to the column 14 by repetitively opening and closing the purge valve 50 and, as a result thereof, the moisture of the dry air passing the inside of the column 14 is able to be more absorbed with the smaller purge flow rate.  The flow of the released dry air is interrupted and the quantity of the dry air necessary for the regeneration of the desiccating agent may be decreased.

Title: Rectification signal generator for brushless motor
Inventor: NAKADA TOMIO
IPC: H02P6/24
Filed: 1987-03-30
Abstract: PURPOSE:To suppress the hunting vibration of a rotor by causing an additional resistance to form in a rectification signal a hysteresis angle according to the direction of rotation. CONSTITUTION:In a rectification signal generator circuit 13 for a brushless motor, a comparison voltage applied to a second input terminal 14b varies with H or L of an output signal Vout, of which output voltage Vout also has a hysteresis angle (d) by the provision of an additional resistance Rf. Therefore, when, for example, an original rectification signal UE0 obtained from a rotational position sensor is inputted as an input signal Vin into a comparator 14, its output signal Vout, i.e. a rectification signal UE is a signal having the hysteresis angle (d) according to the direction of rotation and being in the condition to maintain the former state in any direction of rotation relative to a switching point (a) so that said switching point (a) may have a width. Thus, when phase switching is performed, there is no gap in a phase-switching point and it is possible to prevent a hunting vibration.

Title: Automatic mechanism for prevention of multi-feed in friction feeding system
Inventor: KOKUBO TAKESHI
IPC: B65H3/52
Filed: 1985-04-09
Abstract: PURPOSE:To prevent slips and the like from being feed accompnied with lying one upon another configurating a device in such a way that a separation roller is provided at the tip end of an arm which is pulled so as to always maintain the maximum gap between the separation roller and a picker roller in a feeding device for slips and the like. CONSTITUTION:A slip 1 which is pressed on a pusher roller 2 by a spring (18) force, is fed one by one by rotation of the pusher roller 2. And a separation roller 4 is provided at the tip end of an arm 6 which is capable of swinging. Here, the separation roller is either stationary or does rotate inversely to the feeding direction, and is pulled by a spring 7 to the direction that a gap is widened between a picker roller 3 and the separation roller. When two sheets of slips are fed there, encroaching force into a space between the picker roller 3 and the separation roller 4 becomes great. In this case, if the encroaching force is in excess of tension of the spring 7, the arm 6 starts rotating to the direction that the gap becomes small. This causes slips 1 which are fed while they are overlapped, to be drawn permitting them to be separated forcively.
