Title: Production of ferromagnetic iron oxide powder
Inventor: NISHIO AKIRA
IPC: H01F1/11
Filed: 1983-12-13
Abstract: PURPOSE:To obtain a ferromagnetic iron oxide powder having high coercive force and sharp coercive force distribution, by adding a cobalt salt, a ferrous salt and an alkaline substance to an aqueous suspension of magnetic iron oxide powder, and heating and stirring the mixture in the presence of beads. CONSTITUTION:A cobalt salt such as cobalt sulfate, a ferrous salt such as ferrous sulfate, and an alkaline substance such as sodium hydroxide are added to an aqueous suspension of magnetic iron oxide powder such as gamma-Fe2O3 powder, and the mixture is heated and stirred under usual condition in the presence of beads made of a material inert to the reaction components, e.g. glass beads. The highly cohesive magnetic iron oxide powder can be dispersed uniformly by this process under a relatively mild stirring rate without using a dispersing agent, and at the same time, the produced cobalt-doped iron oxide can be pulverized at the same time to form a uniform layer on the surface of each particle of the magnetic iron oxide powder. A cobalt-doped magnetic iron oxide powder having excellent magnetic characteristics such as high and uniform coercive force and sharp coercive force distribution can be obtained economically by this process.

Title: Pinball feeder
Inventor: KOMIYA YOJI
IPC: A63F7/02
Filed: 1990-09-03
Abstract: PURPOSE:To miniaturize a pinball feeder and improve the reliability thereof by providing a low speed exciting means for sequentially exciting an exciting coil of a stepping motor for a predetermined period in timing slower than the mechanically possible rotational speed of a rotor in at least the start of the stepping motor. CONSTITUTION:While a stepping motor 50 is driven by 1-2 phase excitation, it is driven with a frequency considerably lower than a self-shaft frequency of a rotor in the start. The rotor rotated by the excitation of a certain phase is returned once to the initial rotational position while ball cutting discs 41, 42 are stationary. Even during that period the phase of an exciting pulse given to an exciting coil successively progresses and the rotor repeats the small rotation and swing return under the sliding condition as viewed from a exciting pulse. The rotor begins gradually to vibrate and soon move ball cutting disks 41, 42 against large static friction and inertia moment. This resembles the final start of a plurality of trains against the static friction and inertia by repeating the acceleration and stoppage of a small drive force locomotive.

Title: Electric communication system and transceiver device used for the same
Inventor: YAKOBU KERUKOOFU
IPC: H03H11/02
Filed: 1992-09-02
Abstract: PURPOSE: To inexpensively transmit a low frequency signal with a simple device with thermal conversion. CONSTITUTION: A thin film resistance 6 corresponding to a temperature change is arranged between conductors 2 and 3 provided on one face of an insulating substrate 1 with high heat conductivity. A resistance 7 formed by negative temperature coefficient paste having the temperature coefficient of -6000ppm/K is arranged between conductors 5 and 6. When signal current flows in the resistance 6, the resistance 6 thermally radiates it and it passes through the heat conductive substrate 1. It reaches the resistance 7 and drops the resistance value of the resistance 7. The change of the resistance value is electrically detected and an information signal is obtained. Thus, a transceiver device with the low frequency can easily and inexpensively be obtained.

Title: Manufacture of cmos device
Inventor: FUU-TAI RIYUU
IPC: H01L21/8238
Filed: 1988-09-19
Abstract: PURPOSE: To reduce the number of masking processes, simplify the processes, increase the yield of manufacture and reduce the cost, by utilizing a larger number of non-selective implanting processes. CONSTITUTION: In order to reduce the number of mask processes, a larger number of global, that is, non-selective implanting processes wherein no mark is required to implant the ions of a donor and an acceptor as dopant in a substrate 10, are utilized. Such non-selective implanting processes can be effectively replaced with selective implantation, that is, implantation using masks, in certain stages by suitably limiting the subsequent selective implanting processes. In order to eliminate the necessity of a masking process associated with a selective implantation, for example, a differential oxide growth technique is used to grow a thick oxide layer 40 on silicon with an n-type well exposed and a thin layer 42 on silicon with an p-type well exposed. This enables the improvement of yield and the reduction of cost.

Title: Ultra-low density polyethylene film improved in heat-sealing characteristic
Inventor: IWASE HIROSHI
IPC: B29C59/04
Filed: 1991-09-13
Abstract: PURPOSE:To obtain the heat-fusion strength of a heat sealing section sufficiently even when low molecular weight components bleed on film surfaces by roughening the film surfaces so that low molecular weight component films on the film surfaces are broken when the roughened film surfaces are thermally fused mutually. CONSTITUTION:A film surface is roughened by using embossing rolls 231, to surfaces of which embosses having the height of 0.5-1.0mum of one cooling roll and a diameter of 2.0-3.0mum at intervals of 1.0-2.0mum are formed, in the cooling rolls of a cooling device when a film is manufactured. When the surfaces 11 of the film 10 are superposed mutually, held between a heating upper plate 41 and a heating lower plate 42 and thermally fused through a heat sealing method as an external heating method by heat and pressure, low molecular weight component films hindering heat fusion are broken largely by heat and pressure at the time of heat sealing because the surfaces of thermally fused surface are roughened, and novel interfaces are formed on the thermally fused surfaces, thus increasing the fusion strength of the thermally fused surfaces.

Title: Thermal transfer sheet
Inventor: OHARA SHUICHI
IPC: B41M5/388
Filed: 1988-09-21
Abstract: PURPOSE:To ensure that images recorded on a recording material have a favorable hue of a magenta color, enhance preservability, and enable reductions in recording time and recording energy required for thermal transfer recording by incorporating a dye of a specified chemical structure in an ink layer. CONSTITUTION:An ink layer comprising a dye of formula I is provided on one side of a base. As the base, a plastic sheet about 3 to 10mum thick of polyethylene terephthalate, polyphenylene sulfide or the like is used. It is preferable to use a binder in addition to the dye at the time of providing the dye-containing ink layer on the base. Because of high transferability of the dye from the ink layer of a thermal transfer sheet to a recording material under a fixed thermal energy, images recorded on the recording material have a high recorded density, and recording sensitivity is increased. The dye of formula I has a maximum absorption wavelength of 530nm, and is therefore excellent in hue. In addition, the dye molecule itself has high safety under light, particularly, UV rays, so that preservability of images is enhanced.

Filed: 1988-09-20
Abstract: PURPOSE:To prevent the breakage of bent sections connected to leg sections by allowing a pressing tool to pinch and fix only one leg section between it and a device main body. CONSTITUTION:A pressing tool 38 entering between a pair of leg sections 32a and 32b pinches and holds only one leg section 32a between it and support sections 36a and 35b. No force is applied to a pair of leg sections 32a and 32b to expand them although this pressing tool 38 presses one leg section 32a in the direction apart from the other leg section 32b. No unreasonable force is applied to the leg sections 32a and 32b and bent sections 31 connected to them, and the breakage of a light emitting tube 28 can be prevented even if dispersion occurs on the size precision of the light emitting tube 28. The tip section of the pressing tongue piece 41 of the pressing tool 38 enters the inside of the line X1-X1 connecting the outer peripheries of the leg sections 32a and 32b, thus this pressing tongue piece 41 is not in contact with a globe 42, and the globe 42 can be made compact.

Title: Image recorder and recording method
Inventor: YOSHIDA HAJIME
IPC: B41J2/01
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To control ink ejection time so that fluctuation at the time of manufacturing head supporting mechanism, or the like, is absorbed by delaying the ink ejection time of each nozzle so that positional shift of the nozzle is offset. SOLUTION: Image data for each bit being imparted to each nozzle is delayed by a specified time by a delay circuit 20 of an image data control circuit 15 before being delivered to a head drive circuit 12. The specified time is suitable for correcting the difference between actual recording results and ideal recording results and it can be calculated by reading out the actual recording results by means of an image reader, e.g. a scanner, and comparing it with the ideal recording results. When the maximum delay is set at a large level, relatively large distortion in the linearity of head or so-called kink of each nozzle can be corrected. Since the output timing of image data can be controlled not mechanically but through an electric delay circuit, image recording quality can be enhanced without increasing the number of parts.
