Title: Semiconductor pressure sensor
Inventor: TOMINAGA TAMOTSU
IPC: H01L29/84
Filed: 1979-02-02
Abstract: PURPOSE: To eliminate the dispersion of the characteristics by specifying the structure of the silicon diaphragm as well as the attaching method to the attachment board.  
     CONSTITUTION: Diffusion resistance 2 functioning as the pressure-sensitive part is provided to the single surface of the silicon chip; while oxide film (SiO 2 ) 8 functioning as the pressure receiving surface is formed at part of the opposite flat surface respectively. Thus silicon diaphragm 1 is formed. Then diaphragm 1 is adhered to attachment board 12 via Au-Si eutectic alloy layer 19 which is not adhesive to film 8, and at the same time resistance 2 is connected to metalized wire 20 connected to lead frame 16 via Au wire 21. Thus the pressure receiving area of diaphragm 1 can be decided accurately by the pattern of film 8, and also the film thickness of the receiving surface can be decided accurately by the thickness of silicon chip 9 itself. As a result, the semiconductor pressure sensor featuring the even characteristics can be formed easily.

Title: Transportation passage diverting device
Inventor: KOMATSU TAKAHIKO
IPC: B65H29/60
Filed: 1986-01-20
Abstract: PURPOSE:To divert continuous sheets quickly, by switching a gate for switching a transportation passage of sheets even if the sheets are passing through the gate in a prescribed period of time after a sensor disposed upstream of the gate senses that the sheets pass. CONSTITUTION:A gate 57 for diverting sheets to transportation passages 59, 65 is disposed in a transportation passage 54 of the sheets. An arm 121 is provided with the gate 57 and the gate 57 is actuated by a drive unit 123 mounted on the arm 121 having a solenoid 127 and a spring 129 for returning the gate 57. The solenoid 127 is deenergized in a prescribed period of time after a sensor S disposed upstream of the gate 57 senses the rear end of a sheet to cause the gate to return so that the sheet which is passing through the passage 65 is transported while it is depressed by the gate 57. With such an arrangement, sheets which are continuously supplied are diverted quickly, whereby an operating time of a main device such as a copy machine is reduced.

Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of image quality in binary image data after a variable power processing has been executed by deciding the value of a noted pixel based on the output of a black pixel number counting circuit and the output of a different black pixel number counting circuit. SOLUTION: A black pixel number counting circuit 2 counts the number of black elements in image data for nine pixels, which a 3×3 matrix circuit 11 inputting data from a line memory 10 and outputting binary image data for nine adjacent pixels outputs. A black pixel number counting circuit 15 counts the number of black pixels in picture data for eight pixels outputted from a 3×3 matrix circuit 4 outputting binary image data (except for notice pixel among nine adjacent pixels) for eight adjacent pixels which are power-varied. A comparison circuit 16 compares the outputs Smn and S'k1 of the black pixel number counting circuits 12 and 15. The value of the noted pixel is decided, based on the outputs Smn and S'k1 of the black pixel number counting circuits 12 and 15.  Thus, the deterioration of the image quality of binary image data after a variable power processing is executed is prevented.

Title: Mask focus type color picture tube
Inventor: KANBARA EIJI
IPC: H01J29/81
Filed: 1983-01-28
Abstract: PURPOSE:To obtain a mass-productionable color picture tube by bringing the projection of one of at least two masks higher than that of the other mask thereby achieving strong focusing force more effectively at the mask section while maintaining sufficient mechanical strength. CONSTITUTION:First mask 8 and second mask 7 are provided with projections 24, 23 around the apertures 22, 21 and upon application of potential onto each mask, electric force lines are produced from the projection 24 of mask 8 to the projection 23 of mask 7 to form a tetrode lens system. Consequently the electric force lines will be stronger in the direction perpendicular to the advancing direction of beam when compared with general tubular lens system to increase focusing force. Here since it will function as a disperse lens in Y-Z face while function as a focus lens in X-Y face, a beam spot elongated in Y-axis is produced on screen 1 for impinging electron beam. The focusing force will increase as the heights of projections 24, 23 increase but equivalent focusing force is achieved even the height of projection of one mask is low if the height of the other projection is sufficiently high.

Title: Rice cooking and warming pan
Inventor: MIYAKE KAZUYA
IPC: A47J27/00
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To seal the clearance of a contact part to prevent the leakage of steam within a pan by elastically bringing the peripheral part lower surface of the lower surface member of a lid body into contact with the upper surface of the upper periphery of the pan, and generating a water film by the dew by condensation of steam in the contact part between the lower surface member and the upper periphery of the pan. SOLUTION: In rice cooking and warming, the inner lid 28 of a lid body 25 is heated by a lid heater 41, whereby dew condensation in the lower surface of the inner lid 28 is minimized. Although a minute clearance is caused in the contact part between the peripheral part lower surface of the inner lid 28 and the upper surface of the upper periphery of a pan 4 when the lid body 25 is closed, the clearance is minute and held uniformly since the inner pan 28 is elastically pressed to the upper periphery of the pan 4 by the energizing force of packings 31, 36 and a spring 40. Since the dew by condensation of steam in rice cooking penetrates into the clearance to form a water film, and the clearance of the contact part is surely sealed by the water seal effect by this water film, the leakage of steam between the inner lid 28 and the pan 4 can be prevented.

Title: Method for coiling of metallic band and device therefor
Inventor: AKAO TAKETO
IPC: B21C47/00
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To get rid of the deformation in thin portion of metallic band, to make straightening work needless, and to make the work after uncoiling efficient by detecting the coiled layer height of the band and shifting the axial center of mandrel up or down to keep the pass line of band fixed based on the coiled layer height. SOLUTION: An axial center height control circuit 21, with the input of detecting signal from a coiled layer height detecting sensor 2, adjusts the height of axial center 1A of mandrel 1 based on the detecting signal. The base 5 is made to descend so as to keep the coiled layer height of metallic band 3 and the pass line of deflecter roll 4 always on a straight line. On the other hand, the detecting signal of coiled layer height detecting sensor 2 is outputted to the tensile force control circuit 22 as well.  The tensile force control circuit 22, with the input of the detecting signal from the coiled layer height detecting sensor 2, controls the rotary velocity of motor 9 based on the detecting signal, and thus adjusts the tensile force so as to be the most suitable coiling tension for the coiled layer height so that the tensile force may become smaller when the coiled diameter is small or become larger when the coiled diameter becomes large.

Title: Feed-out mechanism having skew correcting function for paper sheets
Inventor: HOSOYA TAKAHIRO
IPC: B65H9/16
Filed: 1988-01-22
Abstract: PURPOSE:To simplify a mechanism without a separate skew correcting mechanism by providing a pair of right and left skew detecting sensors for detecting skew at the time of feeding out paper sheets. CONSTITUTION:A pressure roller 1 and a picker roller 2 are rotated in the direction of an arrow (a) by a motor to draw out a paper sheet 7. Usually, separation rollers 3a, 3b are not rotated. When skew detecting sensors 6a, 6b positioned just behind a place where a paper sheet is fed out detect skew of the paper sheet 7, a separation roller driving motor 4b positioned on the leading side separation roller 3b side is driven to rotate the separation roller 3b in the opposite direction to the feed-out direction, whereby feed-out resistance against the paper sheet 7 is increased on the leading side so as to lower the speed of feeding out the paper sheet 7. On the opposite separation roller 3a side, the feed-out speed is as usual because shafts 5a, 5b are independent not to be rotated, so that the paper sheet is fed out while the skew state is being corrected.
