Patent JP-H069089-A (JP)
Title: Sheet feeding device
Inventor: YOKOTA MASAHIKO
IPC: B65H3/52
Filed: 1992-06-29
Abstract: PURPOSE:To provide a sheet feeding device in which separation performance can be automatically regulated independently of the kind, condition, and service environment of the sheet by providing a first energizing means for energizing a friction means to a rotary feeding means and a second energizing means for energizing the friction means in the reverse direction to the sheet feeding means. CONSTITUTION:In such a condition that a sheet S is inserted and the foremost end thereof does not reach a separation part, a friction plate 2 moves downstream as a separation roller 1 rotates. At that time, a spring 4 is extended and a tension is caused in the friction plate 2. At the same time, a guide member 5 is pushed up to contract a spring 3, and the pressing force N of the friction plate 2 is increased to heighten the sheet feeding force of the separation roller 1. When a second sheet S2 reaches the separation part, the second sheet S2 is drawn back upstream due to the difference in the magnitude between the pressing force N and the tension F. When the friction plate 2 is drawn back, the pressing force N decreases, and the load to be added to the first sheet S1 decreases.

Title: Recording apparatus and recording method as well as ribbon cassette
Inventor: KATANO KEIJI
IPC: B41J32/00
Filed: 1996-07-01
Abstract: PROBLEM TO BE SOLVED: To carry out a stable cooling separation of an ink ribbon by controlling the driving timing of a peeling pinch roller driving means to be later than the driving initiation timing of a carriage driving means. SOLUTION: The driving initiation of a winding motor for rotating a winding roller driving shaft is controlled to start after the lapse of a specified time from the driving initiation of a carriage driving motor. Thus, an ink ribbon 6 is not wound for the specified period of time and only feeding of the ink ribbon 6 is conducted through traveling of a carriage 7. As a result, the ink ribbon 6 sustains a formation of sagging between a portion recorded by a thermal head 14 and a pulling out pinch roller 4a. Control done in this manner causes separation between the recording paper and the ink ribbon 6 to be implemented in a condition where the ink ribbon 6 is cooled sufficiently. Therefore, changes in the rotation speed of a peeling pinch roller 4a or vibrations caused by expansion of the ink ribbon 6 exert no influence on the carriage 7.

Title: Wavelength converting circuit
Inventor: OKASHITA KAZUHIRO
IPC: H04B10/27
Filed: 1984-08-20
Abstract: PURPOSE:To perform a wavelength conversion with a simple constitution by inputting an electric signal outputted from a photodetector to generate the light of a wide band and branching this light to plural lights different in wavelength and selecting one from these lights. CONSTITUTION:A photodetector 1 converts an optical signal to the electric signal and supplies this signal to a wide band light emitting element 2. When the electric signal outputted from the photodetector 1 is inputted to the element 2, the element 2 generates the light of a wide band and supplies it to an optical demultiplexer device 3. The device 3 branches the light of a wide band outputted from the element 2 to plural lights different in wavelength. An (n)X1 optical switch 4 selects one from plural light different in wavelength which are outputted from the device 3. Consequently, the light inputted to the photodetector 1 is converted to the light having an optional wavelength which can be generated in the device 3. Thus, wavelength conversion is performed with the simple constitution.

Title: Production of optical recording medium
Inventor: KUDO MAKOTO
IPC: G11B7/26
Filed: 1987-07-09
Abstract: PURPOSE:To prevent the excess or deficiency of an adhesive agent and the nonuniformity of an adhesive layer and to avert the intrusion of air bubbles into said layer so that the accuracy of coating is improved and yield is increased by coating the adhesive agent on the substrate while specifying the discontinuous intervals of the adhesive agent at the beginning and end of coating of the adhesive agent to be used for sticking, then sticking the substrates in a vacuum atmosphere. CONSTITUTION:The light transmittable substrate 7 on which a recording layer 3 for information is provided and the light transmittable substrate 9 are stuck to each other via the UV curing adhesive agent 5. While the light transmittable substrate 7 is kept rotated impulsively by a motor 13, the adhesive agent 5 is dropped onto the substrate 7 by using a dispenser 12. The coating is so executed at this time that the discontinuous part 14 of the adhesive agent at the beginning and end of the coating of the adhesive agent is kept within 10% of the coating circumference. The substrates are thereafter stuck to each other in a vacuum atmosphere and finally the adhesive agent is completely cured by using a UV exposing machine. The excess or deficiency of the adhesive agent 5 and the nonuniformity of the adhesive are thereby prevented and the intrusion of the air bubbles into said layer is averted, by which the accuracy of the coating is improved and the yield is increased.

Title: Gravity direction keeping device using symmetrical hanged coupled matter
Inventor: MIYA KENICHI
IPC: G01S7/48
Filed: 1992-06-08
Abstract: PURPOSE:To secure the stability to an optional sloping angle with no influence of the acceleration by keeping the direction connecting the center of an upper coupled matter fixing an oscillating matter to each center of paired lower coupled matters in the gravity direction. CONSTITUTION:When an oscillating matter A is kept at an optional sloping angle theta, a center line QORO of a pair of lower coupled matters Q and R is set horizontal and a pointer I set vertical respectively. Under such conditions, a weight W receives the force Wg. In regard of this force, an impulse element G gives an impulse to a parallel impulse structure H and therefore, the component Wgcostheta caused in the impulse direction is applied to the center QO and RO of the matters Q and R as the force of 1/2Wgcostheta via the lower rotary couplers E1 and E2 and the upper rotary couplers Q1 and R1 respectively. These forces are applied to both centers QO and RO in each radius direction and therefore, no rotary force is produced around an intermediate coupler M. Furthermore, both matters Q and R generate no rotary force around an upper coupler P since both centers QO and RO have the same size and are set in parallel to each other. Thus, the pointer I never loses its attitude. The same working is secured also to the horizontal acceleration.

Title: Driving method for liquid crystal panel
Inventor: TAKAHARA KAZUHIRO
IPC: G02F1/133
Filed: 1989-07-05
Abstract: PURPOSE:To prevent the occurrence of flicker accompanied with reduction of a frame frequency at the time of increasing the number of gradations by distributing a selected field to two or more time areas to display gradations. CONSTITUTION:One frame consists of plural fields, and the number of selected fields is changed to change the duty of the voltage impressed to a liquid crystal cell and the gradation is displayed. In this case, one frame consists of fields whose number (N+alpha) is larger than a number N of gradations except the black level, and all selected field in each gradation are not continuous with respect to time and are distributed to two or more time areas to display the gradation. Consequently, the number of fields is larger than the number of gradations, and two discontinuous fields are selected in one frame in the case of a gradation level 1 following the black level. Thus, the frequency of selected fields is prevented from being increased to coincide with the frequency of one frame, and the occurrence of flicker is reduced.

IPC: G11B7/125
Filed: 1991-06-18
Abstract: PURPOSE: To obtain light of second harmonics generated in the primary mode by providing a waveguide channel of a second section with plural divergent channel branches. CONSTITUTION: Light of a fundamental frequency from a laser diode 12 is coupled to a main channel 20 of a waveguide 18. In the main channel 20, light of the fundamental frequency is converted to light of second harmonics. Light of second harmonics is generated in primary, secondary, and tertiary modes and is made incident on divergent channels 22. When separation distances between divergent channels 22 are increased, light of second harmonics in each mode in the main channel is converted to light of second harmonics in the single mode in each independent divergent channel. Modes of light are divided to independent divergent channels, and it exists as light in the primary mode in each divergent channel. The quantity of light generated in each divergent channel is determined by the frequency of the laser diode 12.

Title: Linear-motor elevator
Inventor: MIZUNO KIMIMOTO
IPC: H02K41/02
Filed: 1994-07-25
Abstract: PURPOSE:To obtain a linear-motor elevator in which a rescue operation can be performed by a method wherein, even when either one armature winding for a double-sided linear motor is discontinued or short-circuited, an armature winding on the other side is used. CONSTITUTION:A right armature 5a and a left armature 5b for a double-sided linear induction motor are electrically separated completly. As a result, even when either one armature coil is short-circuited, a current detected by a DCT 17 is judged to be the detection of an convercurrent by an inverter control circuit 19, and a cage is emergency-stopped. In addition, when either one armature coil is discontinued or when either one power-supply cable is detached or disconnected, a motor current detected by the DCT 17 with reference to an instruction current is reduced to 1/2, it cannot follow the instruction current, and it can be detected by means of simple software or hardware. Thereby, when one atmature for a linear motor installed at a counterweight becomes abnormal, a rescue operation can be performed easily without switching over the interconnection of a power-supply wire.
