Title: Ink jet recording device
Inventor: SHINADA SATOSHI
IPC: B41J2/185
Filed: 1990-05-16
Abstract: PURPOSE:To fix a case member such as a mask board of an ink jet recording head without deformation by fixing the case member such as the mask board with a fastening screw arranged vertically in the longitudinal direction of a through hole on an ink jet substrate. CONSTITUTION:A mask board 4 which is one of case members is fixed using a fastening screw 8 arranged vertically in the longitudinal direction of a through hole 5 on the mask board 4. Subsequently, the mask board 4 is less deformed and thereby, an ink jet recording head 1 is more tightly sealed. Thus the mask board 4 becomes further adhesive with the cap 9 of a head.

Title: Manufacture of lead alloy rolled sheet for storage battery grid
Inventor: KIKUCHI YOUICHI
IPC: H01M4/68
Filed: 1983-07-11
Abstract: PURPOSE:To give a lead alloy rolled sheet mechanical strength enough to supply to an expanding process without age hardening in an annealing chamber. CONSTITUTION:Mechanical strength of rolled lead alloy sheet is increased in such a way that the sheet is wound in a coil form in the final process and heat generated in the rolling process is kept in the coiled sheet to give the sheet annealing effect instead of applying age hardening to the sheet in an annealing chamber. The lead alloy sheet is kept at 60-80 deg.C when the final rolling process is completed. The lead alloy sheet is kept at 50 deg.C or less after completion of the rolling process other than the final rolling process. This invention is especially effective to the rolled sheet of lead-calcium-tin alloy containing 0.05-0.1wt% calcium and 0.1-1.0wt% tin which is used for a maintenance free lead-acid battery.

Title: Image forming device
Inventor: KODAMA HIDEAKI
IPC: G03G15/043
Filed: 1992-05-19
Abstract: PURPOSE:To improve a copying speed and to stabilize an image by providing a reference decision means and a correction means. CONSTITUTION:The surface potential of a photosensitive body 41 is detected by a potential sensor. However, the detected value is irregular in the circumferential direction of the body 41. The irregularity is caused by deflection by the eccentricity of the body 41 or the like. In order to optimally adjust the formation of the image such a condition as the potential V0 of a dark part and the potential Vi of a bright part when a reference toner image is formed should be fixed. Then, the best condition of electrostatic charge quantity and light quantity is previously decided before the image is formed. A latent image pattern equivalent to one round of the body 41 is formed and the potential is detected before the image is formed. Then, the average potential is calculated. Based on the calculated result, the image forming condition is decided. On the other hand, the image forming condition is easily corrected in order to increase the copying speed by forming the latent image at one part of the body 41 based on the condition and detecting the potential when the image is formed.

Title: Copying machine having variable power function
Inventor: ISHIDA HIROSHI
IPC: G03G15/04
Filed: 1986-05-30
Abstract: PURPOSE:To exactly dissipate an electric charge of an unnecessary part of a photosensitive body without providing a blank lamp, by forming a white reflecting part whose width is wider than an original of the maximum size that can be copied, and setting the width of the white reflecting part to a specific size. CONSTITUTION:In case a part of the maximum original width L is exposed, and an image has been formed on the surface of a photosensitive drum 31 by the minimum variable power rate MMIN, a reflected light from the part of the maximum original width L is led to only a range of ZMIN=LXMMIN, of the surface of the photosensitive drum 31, and only an unnecessary electric charge in this part can be dissipated. However, to the part of the outside from ZMIN, a reflected light from a white reflecting part W1 is led, and also, WXMMIN>=ZMAX, therefore, even in the part of the outside from the area ZMIN, an unnecessary electric charge of the surface of the photosensitive drum 31 can be dissipated exactly.

SOLUTION: An oscillation element such as a piezoelectric element 11 for generating an acoustic wave at a small region with a sample 1 is used as a vibration source, and vibration on a sample surface is replaced by translation of a recursive reflection object being adhered to a reflection sheet 20 and is directly measured by a laser Doppler vibrator 30. A detected waveform is inputted to a waveform digital storage device 40 and the detection processing of the small movement of an ultrasonic region due to the overlapping of a digitized waveform is performed, for example, by a data-processing means 50 such as a computer.

Title: Simulator for radar indicator
Inventor: KITAFUJI HIROSHI
IPC: G01S7/40
Filed: 1978-10-16
Abstract: PURPOSE:To readily conduct fine adjustment and inspection of a radar indicator display unit over the entire area by reproducing a signal recorded on a video tape recorder on an input video signal of the indicator, thereby forming a signal similar to an actual echo signal. CONSTITUTION:After a video signal recorded on a video tape recorder 5 is branched to first channel of video and synchronous trigger signals and second channel of X and Y signals, the video signal and trigger signal of the first channel are separated by a video distributor 6, and introduced to a radar indicator 1. The bearing signal of the second channel is divided into X and Y signals by a distributor 9 to thereby form an X-Y signal by an X-Y signal forming circuit 10 and to be then applied to the indicator 1. Thus, the video signal recorded on the recorder 5 is indicated on an indicator display tube 1c of the indicator 1.

Title: Dustproof net of speaker in car
Inventor: MITOBE KUNIO
IPC: H04R7/12
Filed: 1984-06-19
Abstract: PURPOSE:To improve incombustibility, weatherproofness, water proof property etc. by weaving a dustproof net using spun yarn obtained by mixed yarn of short fiber of polyvinyl chloride and short fiber of polyethylene terephtalate. CONSTITUTION:To make the dustproof net 10, equal quantity of short fiber of polyvinyl chloride and short fiber of polyethylene terephtalate is mixed and mixed yarn is obtained by spinning. The net is woven by woven number of warp 30-45/square inch, weft 30-45/square inch. Proportion of mixing of polyvinyl chloride and polyethylene terephtalate may be 30:70-100:0. However, in the case of 100% polyvinyl chloride, thermal resistance becomes inferior. The dustproof net is dyed black for its appearance, and incombustibility is supplemented by soaking small quantity of incombustible agent or black resin. In the case of speaker in a car, as water repellent property is influenced by number of weaving, water proof property is improved by securing coarsenenn that does not cause deformation of the diaphragm.

Title: Processing method for shallow trench isolation structure
Inventor: YO KOKUJI
IPC: H01L21/76
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To reduce stresses caused by an annealing process by forming a doped silicon dioxide layer on a silicon nitride layer to fill a trench, effecting the annealing process, and removing part of the doped silicon dioxide layer by a planarization step to expose the silicon nitride layer. SOLUTION: A doped silicon dioxide layer 110 is formed on a silicon nitride layer 104 to fill a trench 106. The layer 110 is subjected to an annealing process to be highly densified. The annealing process is performed at about 800-950 deg.C. Part of the layer 110 is removed by, e.g. chemical-mechanical polishing to expose the layer 104. The coefficient of thermal expansion and Young's modulus of the layer 110 are adjusted by adjusting the doping level. This reduces stresses caused during the annealing process, and hence reduces both leaks at contacts and at thresholds or below.

Abstract: PURPOSE: Both a main and an auxilliary cylindrical lead-edge treating-cover come close to the peripheral zones of a winding bobbin. Both covers overlap before a lead edge of wire passes through so as to adequately and smoothly treat the wire edge.  
     CONSTITUTION: When a wire 2 on a bobbin 1 is fully wound, a sheave 8 moves to the a-position as indicated, and a main lead-edge treating-cover 9 and an auxilliary lead-edge treating cover 10 both move. Thus, both cover 9, 10 partly overlap each other and push the wire 2 while guiding it. At this time, a main- line-close- lever 6 moves along two-dotted line as indicated. Then, the wire 2 is hooked by catching nails 12', 12' and the lead edge of the wire is cut by a cutter 14. This lead edge is held by a thrust holding wall 9a, guided within both cover 9, 10, and then stopped. This means effectively eliminates splashing out of cut wire strips, and assures smooth and adequate treatment of the lead edge
