Title: Control method for printer
Inventor: OHASHI YASUO
IPC: G06F3/12
Filed: 1992-02-13
Abstract: PURPOSE:To enable instantaneous print-out by developing data on a bit map and printing them after code conversion with emulation corresponding to respective data. CONSTITUTION:Since received data require corresponding emulation information, the information is stored while being correspondent to data by one-to-one, and reception history is formed by additionally storing a user ID or receiving time and the like as well. By making this printing history to be recognized by a user while using a display device or a method such as table printing or the like, code conversion is executed to data desired by the user corresponding to the order or emulation and by performing access to a character generator(CG) 7 with the code, data are converted to a correspondent character pattern. Then, the converted character pattern is developed on the bit map in a DRAM 6. These bit map data are read again, converted to serial data, transferred through a bus 11 and a video interface to a printer engine 10 and printed out.

Abstract: PURPOSE:To realize a semiconductor laser drive circuit capable of detecting maximum rating of optical output reliably and causing a semiconductor laser to stop emission of light by providing means which make a reference voltage of a comparator detecting a voltage of the driving state variable such that it always corresponds to driving current with which an optical output is close to the maximum rating, according to a relation between the driving current and the optical output of the laser. CONSTITUTION:An AD converter 20 attached additionally to a conventional laser drive circuit converts a monitor voltage VM 5 as an analog signal into a digital signal VAD 21. A latch 23 holds digital data from a CPU 22 for setting an optical output and DA 1 converts an output from the latch 23 into an analog voltage VD 9. A latch 25 holds digital data from the CPU 22 for setting a predetermined reference voltage that a comparator 16 uses as a reference. A DA 2 converts an output from the latch 25 into an analog voltage. An output of the comparator 16 is inputted into the CPU 22. If the CPU 22 detects any abnormal optical output, the CPU 22 causes a semiconductor laser 1 to stop emission of light.

Title: Cutting tool made of surface coated silicon nitride-base sintered material excellent in chipping resistance
Inventor: UEDA TOSHIAKI
IPC: C23C14/06
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To manifest excellent chipping resistance even by high-speed intermittent cutting by forming a thermally reactive nitrided layer made from a substrate silicon nitride of a deposited metallic Ti layer to a specific average layer thickness on the surface of a sintered material substrate containing the silicon nitride in a specified proportion. SOLUTION: A silicon nitride-base sintered material substrate contains 80-97 wt.% silicon nitride. The average layer thickness of a thermally reactive nitrided layer formed on the surface of the substrate is 0.1-5 μm. The production of this coated silicon nitride-based cutting tool can be carried out according to, e.g. the following manner: A deposited metallic Ti layer having a prescribed thickness is formed on the surface of the substrate containing the silicon nitride in the above proportion by ion plating, etc., and a thermally reactive nitriding treatment for keeping the resultant substrate at about 600 deg.C in an argon atmosphere under about 250 Torr pressure for a prescribed time is then carried out.  Thereby, a reaction is initiated between the deposited metallic Ti layer and the silicon nitride constituting the silicon nitride-based substrate to form the thermally reactive nitrided layer having the above average layer thickness.

Title: Method of growing garnet thick film
Inventor: HIBIYA TAKETOSHI
IPC: H01F41/28
Filed: 1982-02-22
Abstract: PURPOSE:To prevent garnet being grown from generating a free nucleus and the nucleus from being occulded in the film by a method wherein the degree of over-cooling ofthe garnet thick film is set a value lower than particular temperatures. CONSTITUTION:A garnet thick film (for instance, Gd0.2Y2.8Fe5O12 garnet thick film) is grown on a non-magnetic garnet substrate (for instance, Gd3Ga5O12 substrate) through the epitaxial method. At that time, the garnet thick film is grown at the temp. of excessively cooling lower than 10 deg.C. When the molten liquid is left in the excessively cooled state, the nucleus is not allowed to freely grow. The relation between the stable time during which it is left in the excessively cooled state and the excessively cooling temperature is shown by the drawing (region 4 without the presence of free growth and regin 5 with the presence of free growth). When the excessively cooling temp. is 10 deg.C or lower, no nuclei with be generated even if the molten liquid is left as it was. Thus the garnet nucleus freely generated is prevented from being occulded in the garnet thick film, thereby the material for a optical magnetic element without the diffusion of light of incidence is obtained.

Title: Cut-off control system for current zero point of ac switch
Inventor: KANEDA GENSHIROU
IPC: F02B75/02
Filed: 1989-02-06
Abstract: PURPOSE:To prevent the occurrence of an abnormal high voltage attended with current interruption by using an AC switch so as to surely interrupt a current flowing to an AC circuit including an inductive component at a current zero point. CONSTITUTION:Two series circuit each comprising a switch element 41(42) having no holding current and a diode 43(44) are connected in parallel in a way that the polarity of the diodes 43, 44 is opposite to each other, and the combined circuit is inserted in an AC circuit. As soon as a switching signal is lost, one switch element causing a current of the opposite polarity to the polarity of the current having been flowing in the AC circuit to flow thereto is turned off and other switch element is turned off just after the current having been flowing to the other switch element is zero. Since the other switch element is turned off within 1/4 cycle after the current zero point, no succeeding current flows thereby interrupting the current surely at the zero point. Thus, the generation of an abnormal high voltage is prevented.

Abstract: PURPOSE:To enhance durability, in the base material of a piston with a skirt, by gradually reducing the thickness of the skirt part toward the counter-top side in such a degree that the piston diameter can be uniformly restored at the time of heat treatment, and by applying heating treatment to deform the skirt part and further forming a nitriding film layer on the outer circumferential surface thereof. CONSTITUTION:After the base material 1a of a piston has been molded, the outer circumferential surface thereof is subjected to polishing so that the diameter of the outer circumferential surface of a skirt part 2 is gradually reduced toward the counter- top side. The degree of reduction in the diameter is made to be such that the diameter of the piston can be nearly uniformly restored at the time of heat treatment. The reduction is made to be in regard to the outside diameter. The piston base material 1a thus formed is subjected to heating treatment under the gaseous atmosphere of CO gas or the like, and a nitriding film 5 is formed on the surface of the base material. In this case, the diameter of the piston 1 in the skirt part 2 is nearly uniformly restored by the heating, and since the outer circumferential surface is polished, the thickness of the nitriding layer 5 can be uniformly formed all over the outer circumferential surface of the piston 1.
