Title: Method and circuit for selecting reception frequency and receiving device
Inventor: ITO YUTAKA
IPC: H04B7/08
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To shorten the change-over time of a frequency diversity system. SOLUTION: A change-over control circuit 5 controls a frequency changeover circuit 11 or 12 so as to store a frequency at every radio wave frequency signal, which indicates how many times the radio wave frequency signal is selected in the frequency change-over circuits 11 and 12 and to change-over the radio wave frequency signal in order from a large frequency, which is selected in a system when the reception level of the system being the one not taken-out in a diversity circuit 3 becomes equal to below a threshold. Since there is a correlation between a fading occurrence probability and a frequency at every space route, the probability that the reception level becomes more than the threshold is larger in the radio wave frequency signal with a larger selection frequency so that the average change-over time is shortened by preferentially selecting it.

IPC: H04W16/02
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of the throughput of a radio base station, etc., by transferring data by a multimode through the use of a channel only for adding, when the quantity of the data is huge, at transferring of the data by using a private channel so as to minimize data delay and data scrapping in a mobile object communication system. SOLUTION: When data are being transferred in a state, where a private channel for a terminal 10a between a radio base station 20 and an exchange station 30 is in a simple channel mode, a control part 22 of the station 20 measures a data quantity accumulated in data buffer 23a of the private channel for the terminal 10a. Then, the part 22 decides whether this data accumulated quantity is not smaller than a delay data quantity generating value set in advance. Then, when the data accumulated quantity is not smaller than the delay data quantity generating value, the part 22 requests the station 30 to assign one additional private channel to the terminal 10a via a shared channel. Then, the data are transferred by a multimode by using this added private channel.

Filed: 1984-09-19
Abstract: PURPOSE:To prevent the generation of a differential waveform in the output of an equalizing amplifier at switching from a transmitting period to a receiving period by providing an offset cancelling circuit between a receiving transformer and the equalizing amplifier. CONSTITUTION:The offset cancelling circuit 17 is constituted of a capacitor 12 and a switch 13.

Title: Variable nozzle controller for fast wind channel
Inventor: KASHIMA SO
IPC: G01M9/04
Filed: 1988-08-05
Abstract: PURPOSE:To prevent a thin plate from damaging by providing plural strain detectors, warning means, and speed reducing circuits. CONSTITUTION:Strain signals epsilon0 from the respective strain detectors 30 are supplied to 1st and 2nd comparators 34 and 37. When a signal epsilon0 becomes higher than a reference voltage V1, the output of the comparator 34 rises to 'H' level, a warning circuit 35 operates, and an alarm 36 generates an alarm. Further, when the signal epsilon0 exceeds a reference voltage V2 (V2>V1), the output of the comparator 37 goes up to 'H' level and a safety stop circuit 38 outputs a stop signal S to turn off a power source. Then when the maximum strain generated in the thin plate owing to variance in response among motor-driven jacks of a variable nozzle exceeds a constant set in the trimmer 44 of the speed reducing circuit 43, a function signal (f) decreases below the output of a coefficient multiplier 41. A low-signal selector 47 selects and outputs the signal (f) to an integrator 42 and the variation rate of a Mach target value signal Mt decreases to reduce the operating speed of the motor-driven jack.

Title: Device for stacking spinning sliver in can
Inventor: HERUMAN GATSUSERU
IPC: B65H54/80
Filed: 1989-07-28
Abstract: PURPOSE: To extract a sliver without damaging it by providing a pressure member directed to a static wall and movable with a curved delivery pipe on the back of a mouth part of the curved delivery pipe. CONSTITUTION: As a sliver 14 passes a gas injector 9, pressure in an air tube 10 rises. Supply of air to the gas injector 9 is thus disconnected by a control circuit 17. At this instant, air existing forward a mouth part of the gas injector 9 can escape through an air discharge slot 26. As the sliver 14 is clamped between a pressure member 15 and a static cylindrical wall 13 by wedge action, transfer of the sliver 14 by a curved delivery pipe 6 is performed by this clamp action only. The sliver 14 is thus held at a specified position on the cylindrical wall 13 by the pressure member 15, while the curved delivery pipe 6 rotates together with a rotary plate.

Title: Image pickup device
Inventor: YOKOYAMA TOSHIHIKO
IPC: H04N5/351
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To prevent production of a white level distortion owing to a saturated dynamic range of a highlight part when a drive mode of a CCD is switched from a field storage mode into a frame storage mode. SOLUTION: In the field storage mode, an electric signal from a CCD 105 is compared with a reference level (REF) 13 and an aperture of an iris 102 is controlled based on the result of comparison. In the frame storage mode, an electric signal in the field storage mode held in an S/H 12 is compared with a reference level (REF/2) 14 and the aperture of the iris 102 is controlled to be a half in the field storage mode based on the result of comparison. As a result, since an exposure on an image pickup face of the CCD 105 is kept constant before and after the revision of the drive mode, the dynamic range in the frame storage mode is not deficient.

Title: Method and device for rubbing
Inventor: ICHIKAWA TADAHIKO
IPC: G02F1/1337
Filed: 1990-07-24
Abstract: PURPOSE:To improve the quality of a liquid crystal display device and to improve its manufacture yield by rubbing a liquid crystal substrate in the same direction as or opposite direction from the rotating direction of a rotary drum and then rubbing it again in the opposite direction from the rubbing direction at a higher frequency. CONSTITUTION:Right after the oriented film is rubbed in the same direction as or opposite direction from the rotating direction of the rotary drum 3, the film is further rubbed more times than said rubbing in the opposite direction from said rubbing direction. The width of a unoriented area (a) nearby a signal line part 7 is reducible almost to the width of a part (b). For example, the film is rubbed forward more times right after being rubbed backward so as to increase the forward orientation restraining force. Consequently, the unoriented area nearby the signal line part at a picture element periphery is reduced, liquid crystal is uniformly oriented by increasing the orientation restraining force and influence effect of a picture element center part, and the quality of the liquid crystal display device and its manufacture yield can be improved.

Title: Multiplication circuit for finite field
Inventor: TODOROKI TOSHIYA
IPC: H03M13/00
Filed: 1990-07-25
Abstract: PURPOSE:To realize the calculation at a medium speed without increasing the circuit scale by replacing the multiplication of elements of a finite field GF(2<2n>) into multiplication in a subfield GF(2<n>), expressing the result of multiplication in a dual base and obtaining a coefficient of each vector of the dual base serially. CONSTITUTION:The multiplication of elements of a finite field GF(2<2n>) is replaced into multiplication in a subfield GF(2<n>) by using a dual base {omega0, omega1} of a base {1, beta} on the subfield GF(2<n>) of the finite field GF(2<2n>). The result of multiplication is expressed in the dual base {omega0, omega1} and a coefficient of each vector {omega0, omega1} of the dual base is obtained serially. As a result, although the circuit scale is increased more than the scale of the circuit devised by Barleycap, the multiplication speed is improved, and although the multiplication speed is more or less slower than the speed of the circuit devised by Morii/ Kasahara, the circuit scale is considerably reduced. That is, the circuit is realized in which the calculation is sufficiently executed at the operation speed of a medium speed such as several Mb/s and the circuit scale is not increased.
