Title: Mobile radio communication system and position detection method for mobile station
Inventor: SUGIURA MASAKI
IPC: H04W4/02
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a position detection method for a radio mobile station by which the position of mobile station is accurately and simply obtained. SOLUTION: A mobile station 101 measures a reception radio wave strength from a plurality of base stations 105, 109, 110 at a measurement point and reports the result of measurement to a control station 111 via the base stations 105, 109, 110. The control station 111 learns a correlation between the reception radio wave strength and the position of the mobile station 101 by using a neural network based on the measurement results at a plurality of measurement points and positions of the measurement points. When the mobile station 101 reports the reception radio wave strength measured at an optional point to the control station 111, the control station 111 estimates the position of the mobile station 101 causing the measurement result based on the correlation obtained through the learning.  The position of the mobile station 101 is made possible by learning the correlation between the measurement point and the reception radio wave strength.

Title: Focusing device and optical system
Inventor: ITOU YUUJI
IPC: G02F1/19
Filed: 1980-06-24
Abstract: PURPOSE:To control focusing without the attachment/detachment of a focusing mark mask by forming the image of the mask composed of electric optical elements with plural lights refracted and separated by a double-wedge prism. CONSTITUTION:An incident light is refracted by a double-wedge prism 3 for light splitting and separated into plural lights. Two images of a focusing mark mask formed by the part, in which transparent electrodes 9 and 9' to which driving voltages are applied and which are composed of liquid crystal 8 forming electric optical elements are overlapped, are image-formed by two lights. When an objective lens or the like is moved so that 2 images are overlapped so as to become a single image, the optical system is focused. When the switch S is opened after focusing, the focusing mark mask is not formed, making it possible to control focusing without the attachment/detachment of the mask. The same result is obtained when electrocromy is used instead of liquid crystal.

Abstract: PURPOSE:To prevent the excessive discharge of toner caused by the opening of an upper part and to suppress the discharge of the developer soared up by an impact at the time of opening the upper part by providing a developer discarding port on a side opposite to the rotary supporting point side of a developing device. CONSTITUTION:When the upper part of a copying machine is opened, the developing device 8 is inclined accompanying the opening, but the developer discarding port 19b is formed on a surface opposite to the side of a supporting point for opening/ closing on the developing device 8, so that the developer D in the developing device 8 is moved and gathered to the side opposite to the developer discarding port 19b. Therefore, the excessive discharge of the developer D from the developer discarding port 19b caused by the movement of the developer D due to the inclination of the developing device 8 when the upper part of the copying machine is opened, is prevented. Moreover, the excessive discharge of the developer D from the developer discarding port 19b caused by the soaring up of the developer D in the developing device 8 due to the impact at the time of opening the upper part of the copying machine, is suppressed. Further, this mechanism is obtained without providing a shutter mechanism opening/closing the developer discarding port 19b, so that cost is reduced.

Filed: 1993-03-19
Abstract: PURPOSE:To improve the picture quality regardless of the quantity of motion by forming an evaluation value representing fidelity of timewise fluctuation of quantization data against timewise fluctuation of an original signal and varying a weight coefficient of the evaluation value depending on the timewise fluctuation quantity. CONSTITUTION:A quantization circuit 14 generates a median Yt<0> the same as that generated by conventional quantization, upper data YtH incrementing the median by 1 and lower data YtL decrementing the median by 1. Evaluation values QH, Q<0>, QL representing fidelity in a time direction are formed respectively with respect to each object. Then a weight coefficient alpha generated by alphagenerating circuits 38, 39, 40 is multiplied by the evaluation values. The weight coefficient alpha is decided as alpha=c/(Xt-1-Xt) corresponding to timewise fluctuation (Xt-1-Xt) of an original signal, where (c) is a constant. Then a discrimination circuit 19 decides a minimum value among the evaluation values multiplied by alpha and a quantization data object corresponding to it is selected by a selector 18.

Title: Ultrasonic motor
Inventor: ICHIKAWA SATOSHI
IPC: H02K11/00
Filed: 1990-03-30
Abstract: PURPOSE:To facilitate adjustment of a resonance frequency of a resonant circuit by constructing the resonant circuit of a thin-film resistor, an inductance and a capacitor by connecting one end of the thin-film resistor to an electrode for driving and the other end thereof to a driving circuit electrically, and by varying the resistance value of the thin-film resistor. CONSTITUTION:A trimming resistor 20 is provided, a lead wire 22 is connected thereto and then a current is made to flow between a supply voltage +E and the ground. While a frequency at which the current becomes minimum, i.e., a resonance frequency, is measured, a cut 30 is formed in the trimming resistor 20 by a laser beam. As the cut 30 in the trimming resistor 20 is enlarged, it turns difficult for the current to flow in the vicinity of the cut 30, and therefore a resistance value Ra of the trimming resistor 20 increases gradually. When the resistance value Ra becomes a certain value, the resonance frequency coincides with an optimum driving frequency. Therefore application of the laser beam is stopped and formation of the cut 30 is ended.

Filed: 1987-04-08
Abstract: PURPOSE:To cope with central processing units CPU having different bus cycle timings by extracting the fetch bus cycle timing of an instruction code to be executed so that the trigger break is applied with only an address to be executed. CONSTITUTION:An executing cycle number/operation code fetch detecting means 2 detects the bus cycle timing which fetches an instruction code. At the same time, a branch instruction deciding circuit 4 detects a branch instruction. Then an executing instruction fetch timing generating circuit 3 obtains only the bus cycle timing to fetch a branch instruction from said two detection signals. Thus the trigger break is possible with only the executed address by using an extracted signal to a trigger deciding circuit. As a result, the program debugging workability is improved.
