Patent JP-H0243508-A (JP)
Title: Image guide device
Inventor: TANAKA HIROYUKI
IPC: G02F1/35
Filed: 1988-08-03
Abstract: PURPOSE:To execute amplification based upon the inverted distribution of rare earth elements due to exciting light and induced emission due to transmitted light beams by irradiating an image guide body with exciting light beams projected from an exciting light source. CONSTITUTION:Reflected light beams from an object 2 are inputted to an image guide 3 through an objective part 1 and respective picture elements are transmitted through many optical fibers and attenuated during the transmission. The attenuated transmission light is inputted to the image guide body 5 through a connector 4 and transmitted in each picture element by many optical fibers so as to be amplified during the transmission. Since rare earth elements are doped in the cores of many optical fibers, the rare earth elements are inversionally distributed by excited light beams generated from the exciting light source 7 and inducively emitted by transmission light beams to amplify the transmission light beams. Consequently, transmission light beams outputted from an eyepiece 6 can be prevented from being deteriorated and the high brightness and clearness can be attained.

Abstract: PURPOSE:To make an electrodeposited metal sufficiently porous in the method for producing a porous forming die by depositing the porous metal on the surface of a matrix by electroforming. CONSTITUTION:The surface of the conductive part of a matrix 1 is made porous by electrodepositing an insulating part in the form of innumerable fine spots. When electroforming is carried out, a nickel electrode 10 and the matrix 1 are arranged in an electroforming bath 8 (electrolyte 9), and a DC current is applied between the electrode and matrix. Many fine bubbles of gaseous hydrogen are generated on the matrix 1 surface, and the nickel is entrained by the bubbles and deposited. A surfactant is added to the electrolyte 2 to increase the surface tension, the bubble is hardly released from the surface of the matrix 1 and that of the electrodeposited nickel, and a forming die made sufficiently porous is obtained.

Title: Alkaline manganese cell
Inventor: NAGAMINE AKIO
IPC: H01M4/50
Filed: 1981-12-02
Abstract: PURPOSE:An alkaline manganese cell, in which a large amount of alkaline electrolyte is held to improve a cell characteristic by modifying a positive electrode  compound with a mixture of electrolytic manganese dioxide, manganese dioxide  hydrate and carbonaceous conductive agent. CONSTITUTION:A mixture obtained by stirring to mix electrolytic manganese dioxide, manganese dioxide hydrate and carbonaceous conductive agent or the like is used to modify a positive electrode compound in an alkaline manganese cell. A quantity of manganese dioxide hydrate in this mixture is arranged about 5-20% the total quantity of manganese dioxide. This positive electrode compound, being not mixed with an alkaline electrolyte, never absorbs carbonic gas in the air and can prevent increase of internal resistance and deterioration of a low temperature characteristic of the cell. Further existence of manganese dioxide hydrate can hold a large amount of alkaline electrolyte, and the low temperature characteristic and rapid discharge characteristic can be improved.

Title: Machining of blow formed product
Inventor: SAWAGAMI SEIICHI
IPC: B23Q11/00
Filed: 1987-08-05
Abstract: PURPOSE:To prevent chips from staying in a cavity by sending compressed air from a hole formed before machining the opening section thereof to a cavity section and discharging chips outside from said opening section simultaneously with machining. CONSTITUTION:A small hole 3 is made by a drill or the like after a body 1 is formed by blow forming. In the next step, a pipe 6 is connected to the hole 3 in the step of forming an opening section 2, and the opening section 2 is machined by a milling machine or the like. And compressed air is sent to the cavity 5 through the pipe 6 from the small hole 3 simultaneously with the start of machining by the milling machine or the like. This discharges chips B producted in machining the opening section 2 outside the body 1 at the same time of the production of chips by the pressure of the compressed air flowed and prevents the chips from entering the cavity 5. Therefore, this leads to the elimination of such state that the chips B stay in the cavity 5 after the completion of products and prevent blowed products from reducing in the price due to the staying of the chips B.

Filed: 1985-09-03
Abstract: PURPOSE:To calculate a variation range of the input signals with high accuracy and with no fear of overflow even with the signals out of said variation range, by providing a barrel shifter, an overflow detector and an overflow corrector to a multiplying circuit having its variation range of input signals fixed between -1 and +1. CONSTITUTION:A multiplier 5 delivers the value of (2N-1) bits as a product and a barrel shifter 6 shifts the output of a multiplier 5 in the upper direction by an amount equivalent to the value (K+L) given from an input terminal 7 for shift amount. Then the shifter 6 delivers N bits between the (K+L+1)-th bit and the (K+L+N+1)-th bit of the input given to the shifter 6. An overflow detector 10 checks the upper (K+L+1) bits of the output of the multiplier 5 and decides the generation of an overflow when all bits have no equal value. Therefore an instruction is given to a selection circuit 11 so that the negative maximum value given from an input terminal 9 for negative maximum value with the highest bit of the multiplier 5 set at '1' and that the positive maximum value given from an input terminal 8 for positive maximum value is delivered through an output terminal 12 when said highest bit is set at '0', respectively.

Title: Collating system for character pattern
Inventor: KAMATA HIROSHI
IPC: G06K9/46
Filed: 1985-09-04
Abstract: PURPOSE:To improve the collating efficiency of character patterns and to shorten the collating time by deciding a key separator point among those approximate separator points to delete undesired segments and securing the correspondence of segments even though no contact nor intersecting point is not detected with a traced character and securing the accurate correspondence between model characters and traced characters. CONSTITUTION:The data on the separator point is extracted previously out of the model characters and stored in a storing part for separator points of model characters. A selecting part 17 for separator points of model characters selects the segments of model characters to be collated with the segments of traced characters out of the part 16 and stored in a storing part 18 for separator points to be collated. A collating part 19 collates successively the segment data stored in the part 18 with those stored in a storing part 15 for separator points of traced characters and calculates a distance to show the degree of coincidence. Then an uncorresponding state is decided when the minimum distance is larger than the prescribed threshold value S3.

Abstract: PURPOSE:To enable the quantity of the linear displacement of an object being measured to be accurately measured by providing a movable photosensitive element between first and second photosensitive elements and utilizing the signals of the first and second photosensitive elements for measuring the quantity of light received by the movable photosensitive element. CONSTITUTION:A light source 4 and a lens system 6 are arranged in a housing 2. Two photosensitive elements 12 and 14 spaced by a predetermined distance are fixed in a region O irradiated by the light collected or diffused by the lens system 6 and another photosensitive element 8 is movably arranged between the two photosensitive elements 12 and 14. The elements 12 and 14 measure the initial point light quantity and the end point light quantity, respectively, of the light from the lens system 6 and the element 8 measures the quantity of light changing with a distance through which the element 8 is displaced between the element 12 and 14. The elements 12, 14 and 8 transmit the values thus measured as electric signals S1, S2 and S, respectively, to the differential amplifiers 32 and 38 of a control circuit 24. Those signals are converted 34, 30 to digital signals A and b, respectively, and a ratio B/A is computed 36 to be inputted to a position deciding circuit 42. The ratio B/A is compared with a light-quantity-position relationship recording signal P0 recorded in advance and converted to a position signal P. Then, the signal P is converted 44 to an analog signal and outputted to, for example, the controller of an X-Y table.
