Filed: 1986-05-23
Abstract: PURPOSE:To miniaturize a tractor and reduce a driving load by guiding a pin belt by means of a small diameter roller by which a part of the curved part of said pin belt on the opposite side of a driving pulley is inscribed, and reducing a distance between a guide shaft and the outer periphery of said pin belt.

Title: Feed roller member
Inventor: SAKAMOTO TAKAHIRO
IPC: B65H3/06
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To easily recover a function even if a feed failure is caused by the degradation by abrasion of a rubber roller member or sticking of paper powder by forming a feed roller member by laminating plural rubber layers. SOLUTION: A thin rubber layer 3 is formed on a base material 2 of a rubber roller member 1 by being wound in a multilayer shape, and since the rubber roller member 1 is incorporated into a feed roller, both integrally rotates, and rotates only by single rotation at feeding time. At this time, the feed roller rotates while pushing down a sheet loaded on a pressure plate, and the sheet loaded on the pressure plate is separated/carried one by one from the uppermost part. When a feed failure is caused by abrasion of the surface of the rubber roller member 1 or stiking of paper powder since such operation is repeatedly performed, a new rubber layer appears by tearing off a single sheet of rubber layers 3 of the outermost periphery of the rubber roller member 1, so that the feed failure can be improved.  Therefore, a function of the degraded rubber roller member can be restored by simple operation.

Title: Wire dot printer head drive
Inventor: NAKANO SHOICHI
IPC: B41J2/30
Filed: 1988-05-16
Abstract: PURPOSE:To uniform the print density, to shorten the printing time interval and to enable high speed printing, by driving an actuator with output lower than that from a print drive section upon elapse of a predetermined time after detection of collision of a wire against a platen thereby making constant the impact force of the wire. CONSTITUTION:When a CPU 11 receives a print signal, a print drive section 12 produces drive pulses for a time (t1) to drive an armature thus hitting a wire against a platen. At this instance, a piezoelectric sensor 16 detects the collision time. Upon elapse of time (t2) after reception of a detection signal from the piezoelectric sensor 16, a brake control section 13 produces drive pulses for a time (t3). The drive pulses are amplified through a head drive circuit 15 and applied onto an electromagnetic coil, but since the output from the brake drive section 13 is low, brake force is only applied onto reset operation of the armature which is reset together with the wire. Since the armature is reset with weakened reset energy, the wire is settled quickly to a regular starting position.

Abstract: PURPOSE:To obtain a mirror finished resonance surface at a high accuracy free from strain with a small pressing force by cleaving a crystal wafer with directly concentrating necessary stress on the intended portion thereof when a resonance surface is formed for a multidimensional semiconductor laser element. CONSTITUTION:When forming mesa stripe type semiconductor laser elements, first, a buffer layer 2, an active layer 3 and a top layer 4 are epitaxially grown on the sequentially (100) of a multidimensional semiconductor substrate 1 in vapor phase to make a double hetero structure.

Title: Antenna system
Inventor: ENDO SUMIO
IPC: H04B1/3822
Filed: 1990-05-08
Abstract: PURPOSE:To decrease the number of filter stages and to realize this inexpensive and small-sized antenna system by constituting the antenna systems for reception and transmission separately and also forming filters for reception and transmission separately. CONSTITUTION:A reception antenna 11 and a transmission antenna 12 are bound so as to be in parallel by an insulation bar 25 and fitted to the enclosure 26 of a portable telephone set so as to be freely pulled out. And the lengths of the antennas 11, 12 are selected to be lambda/4 or 3lambda/4 with respect to reception and transmission frequency respectively. A controller 15 outputs a channel control signal to a frequency synthesizer 21 and a filter coefficient 23 by the designation from a base station. The synthesizer 21 generates a local oscillating frequency and sends it to a receiver 14 and a transmitter 19. The filter controller 23 gives a control voltage to voltage variable diodes 32, 34 and a coupling capacitor 33 via a choke coil of a reception filter 13 and a transmission filter 20. Thus, the reception filter 13 and the transmission filter 20 are respectively tuned to the reception frequency and the transmission frequency. Since the transmission signal is not intruded into the receiver and the number of filter stages is reduced, the antenna system is miniaturized and the cost is reduced.

Abstract: PROBLEM TO BE SOLVED: To receive radio waves, while avoiding the effect of current flowing though a circuit board by providing a 2nd antenna at a position where currents flowing to a conductive substrate cancel each other. SOLUTION: A whip antenna 2 is provided at an edge part of a circuit board 1.

Abstract: PROBLEM TO BE SOLVED: To keep a probe from coming into contact with sample even in the observation of a sample with sharp uneveness. SOLUTION: Output signal of a waveform shaping device 12 having information on vertical vibration of a cantilever is converted to a voltage VVf corresponding to a vibration frequency by an FM demodulator 14, and the voltage VVf is sent to a displacement value comparator 27. An output signal of a waveform shaping device 24 having information on parallel vibration of the cantilever is converted to a voltage VHf corresponding to the vibration frequency by an FM demodulator 26, and the voltage signal VHf is sent to the displacement value comparator 27. As the voltage signal VHf of the FM demodulator 26 becomes smaller than a reference voltage VH0 , the displacement value comparator 27 is made to multiply the voltage signal VHf by K and sends a signal obtained by subtracting K VHf from a voltage signal VVf from the FM demodulator 14 to an error amplifier 15.  The error amplifier 15 determines a difference signal between the resulting voltage and a reference voltage V0 to be sent to a Z scanner drive circuit 17 through a filter 16.
