Title: Guide assisting system for visually handicapped person and device therefor
Inventor: KUBOTA TSUGUO
IPC: G01S13/75
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To simplify construction and enable smooth and safe guide assistance at a low cost by laying a resonating means having an LC resonance circuit for oscillating an echo wave in response and resonance with a wave, transmitting a wave to the resonating means to receive an echo wave, and outputting guide information corresponding to the echo wave. SOLUTION: When a visually handicapped person confirms the destination by a braille plate 19, and scans a resonance label 2 on the floor surface 18 by a stick 9 incorporating an antenna 3 connected to a portable scanner 4, waves are transmitted from a transmit/receive circuit 5 of the portable scanner 4 through the antenna 3. In resonance with the waves, the resonance label 2 transmits an echo wave, and the echo wave is received by the transmit/receive circuit 5 in the portable scanner 4 through the antenna 3 in the stick 9. The received echo wave is collated with plural data previously set in a memory by a detecting circuit 6, and the data corresponding to the received inherent echo wave is selected and converted to a voice to be output from a speaker 7 by an output circuit 8.

Abstract: PURPOSE: To provide a coding/decoding device for realizing a high compressibility with multilevel signal as object. CONSTITUTION: This device is constituted of a state number setting means 101 for setting the number of states of a coding object symbol, an occurrence probability prediction means 104 for predicting the occurrence probability, an arithmetic coding means 105 for calculating a code word based on the principle of arithmetic codes and an occurrence probability correction means 106 for assigning the occurrence probability of a fixed value for the symbol state value of a low order.  The occurrence probability value of the coding object symbol is predicted in the occurrence probability prediction means 104, the occurrence probability values belonging to the symbol state value of the low order (the occurrence probability is low) among the predicted occurrence probability values are integrated in the occurrence probability correction means 106, the number of states to be arithmetically processed is reduced and a coding processing or a decoding processing is executed. Thus, this coding/decoding device for realizing the high compressibility is realized by simple constitution.

Inventor: KASHIHARA MASAKAZU
IPC: G01N3/00
Filed: 1988-07-01
Abstract: PURPOSE:To determine a change in width at a high accuracy by a method wherein a planar tension test piece is grasped with a pair of grasping devices across the thickness thereof to measure a width thereof by a pair of displacement measuring means provided integral with the grasping devices through a support. CONSTITUTION:A tension test piece 6 is inserted loosely into a through hole 1a of a support 1 and both ends of the tension test piece 6 is held on a chuck. Then, abutting elements 8a and 8b are positioned almost at the center of the tension test piece 6. Here, the support 1 and differential transformers 2a and 2b are supported at a fixed position by a grasping force of the abutting elements 8a and 8b biased by an elastic member. Thus, when the chuck is set on a tension testing machine to perform a tension test for the tension test piece 6 in a specified process, a width W thereof reduces with an elongation of the tension test piece 6. With the reduction in the width W, measuring elements 4a and 4b are displaced and displacement detection signals SA and SB indicating the displacements thereof are outputted thereby calculating an actual width W based on the signals SA and SB.

Title: Recorder and method for detecting ink
Inventor: YAMAMOTO TSUNESUKE
IPC: B41J2/175
Filed: 1993-06-30
Abstract: PURPOSE:To provide a recorder and a method for detecting ink by which ink is detected easily and surely. CONSTITUTION:In the case of detecting whether ink supplied into a head 1 remains, firstly thermal energy is impressed from a heater 20 to ink is such a degree that discharge of ink does not occur. The temperature of the head at the time is measured by a sensor. Then thermal energy is impressed in such a degree that discharge of ink occurs. The temperature of the head at the time is measured. When ink exists, a part of impressed heat is exhausted together with ink. Therefore the temperature is lowered in comparison with the case where ink does not exist. Furthermore, in order to correct the solid difference of the head, the ratio of above-mentioned both temperatures is calculated and compared with the preset reference value to judge whether ink remains.

Inventor: KASAHARA NOBUO
IPC: G03G15/04
Filed: 1983-09-07
Abstract: PURPOSE:To prevent a position shift and jitters, cause neither defocusing nor deviation in magnification, etc., and prolong the life of a wire rope by providing a driving source for scan return to the pulley drive transmitting means of the scanning speed switching device of a variable power electrophotographic copying machine. CONSTITUTION:An optical scanner is scanned and returned by changing the driving directions of the wire rope 56 for mirror drive wound around a scan driving pulley 30, and when the optical scanner is returned, the scan driving pulley 30 is rotated and reversed. The turning force of a motor 61 for scan return is not transmitted directly to the wire rope 56 for mirror drive and its overall length may be short, so the stress to the wire rope 56 is small and the rope becomes hard to elongate. Therefore, a position shift and jitters due to the elongation of the wire rope 56 are prevented, defocusing, deviation in magnification, etc., are prevented, and the life of the rope is prolonged.

Title: Image forming device
Inventor: INUZUKA TSUNEKI
IPC: B65H5/06
Filed: 1979-12-15
Abstract: PURPOSE: To regulate the pressure of a pressure roller used for an image forming device with simple constitution by detecting the pressure by means of a pressure- sensitive conductive rubber of a pressurizing mechanism and controlling the roller pressing force.  
     CONSTITUTION: A conductive piezoelectric rubber 7 together with a gear head 8, a shaft 4, etc. driven by a DC servomotor 9 form a pressurizing mechanism. When a transistor (TR) Q2 is turned off by a CPU at the starting of copying, the voltage corresponding to the pressing force detected by the rubber 7 is applied to the other of an operational amplifier Q1 to which the reference voltage corresponding to the predetermined pressure is applied. This causes the motor 9 to be servo-controlled via the amplifier Q1, so that the pressing forces of the rollers 1, 2 are kept as specified. On the other hand, when the TRQ2 conducts and the reference voltage lowers at the end of copying, the motor 9 turns until it is stopped by an operational amplifier Q4 and transistor Q5 to which predetermined pressurizing voltage and detected pressure voltage are applied via the amplifier Q1, thus the generation of unnecessary pressing forces between the rollers 1 and 2 is prevented while not in use, and the pressing force of the rollers for copying machine is controlled with the simple constitution.

Abstract: PURPOSE: To shorten time required to grind a retainer and an inner ring and reduce machining cost by partially grinding only an area receiving load within a range of an operating angle, taken by an outer ring and the inner ring, on at least one face out of the outer and inner peripheral surface of the retainer and the outer peripheral surface of the inner rind. CONSTITUTION: After forming a partial spherical surface 4'b1 and a tapered face 4'b2 on the peripheral surface 4'b of a retainer 4' by cutting, the peripheral surface 4'b is ground into specified radius of curvature (R1 ) so as to partially grind only the partial spherical surface 4'b1 of the peripheral surface 4'b of the retainer 4'. After forming the peripheral surface 2'a of an inner ring 2' into radius of curvature R4 slightly smaller than radius of curvature R3 by cutting, the peripheral surface 2'a is ground into the radius of curvature R3 so as to partially grind only an offset center part 2'a1 on the peripheral surface 2'a of the inner ring 2'. In this way, time required to grind the peripheral surface 4'b of the retainer 4' and the peripheral surface 2'a of the inner ring 2' is shortened, and the wear quantity of a grinding wheel is reduced by that part.  As a result, machining cost is reduced.
