Title: Manufacture of manganese or manganese-base alloy ingot
Inventor: ONO SEIO
IPC: C22C1/02
Filed: 1978-07-31
Abstract: PURPOSE: To economically manufacture a manganese or manganese alloy ingot of high quality, by melting a raw material under an atmosphere of inert gas in a plasma arc furnace and solidifying the molten material.  
     CONSTITUTION: The raw material is conducted from a storage vessel 4 into a scull crucible 3 through a feeder 5. The scull crucible is located in a melting chamber 1. The air in the furnace 1 is removed in the direction of the arrow. The inert gas such as argon is then introduced into the furnace so that the pressure in the furnace becomes 0.5 to 10 atmosphere. The pressure is regulated by a pressure control valve 6. Plasma 9 is produced by energization to melt the material in the crucible 3. The plasma is thereafter turned off. The molten material is solidified in the crusible 3 or poured into a mold 10, thereby marking the ingot. This ingot can be manufactured by a continuous melting and casting system different from said furnace. The ingot is appropriate as a magnetic material, hydrogen occluder or the like.

Title: Printer control device
Inventor: TANAKA YOSHIRO
IPC: B41J2/325
Filed: 1995-04-18
Abstract: PURPOSE: To shorten a time for forming images by changing an image forming range in a direction rectangular to the scanning direction so as to make a scanning quantity of a head become least. CONSTITUTION: A sum of scanned quantities of a print head in the case that a print start position is decided based on a first line position of a printing data and in the case that the print start position is decided based on a final line position of the printing data, with respect to a printing area 41, is calculated. Operation of the print head is started from the print start position whose sum of the scanned quantity by the print head is smaller. Thus, when the print start position is decided based on the first line position of the printing area 41, scanning should be done by 500 columns at each time of first and second scannings. However, when the print start position is decided based on the final line position, scanning of only a total 550 columns which is a sum of 50 columns at a first scanning time and 500 columns at a second scanning time suffices.

Abstract: PURPOSE:To ensure an accurate control of the reading head at the prescribed position, by setting the rotational cycle of the optical disk longer than the 1-frame cycle of the static picture and then recording the puseudo picture signal after recording the 1-frame picture signal. CONSTITUTION:The picture signal is generated from picture signal generating part 2 based on the picture obtained through video camera 1 and then extracted out of the 1st gate 3 by an amount equivalent to one frame. These extracted picture signals are then applied to optical modulator 7 after the FM modulation and the shaping of waveform. The laser beam is transmitted to modulator 7 and then modulated based on the above-mentioned picture signal to be condensed on optical disk 9 and then form the optical signal recording hole. Gate circuit 3 generates the control signal to the 2nd gate circuit 11 after transmitting the picture signals equivalent to one frame, and then generates the puseudo picture signals. The puseudo picture signals are extinguished with one rotation of disk 9. The track servo control becomes possible for the reading head by the optical recording hole based on the puseudo picture signal.

Title: Manufacture of electrode plate for lead storage battery
Inventor: KOBAYASHI YOSHIHIRO
IPC: H01M4/82
Filed: 1979-07-23
Abstract: PURPOSE:To prepare a thin electrode plate by fusing a lead plate or a lead-alloy plate and a synthetic-resin frame, with another resin layer interposed between them, and causing the three components to be united, and by filling a paste on this plate; the resin layer has a lower melting point than the resin for the frame.

A layer 3 of resin B having a lower melting point than an acid-proof resin A such as polyethylene, polypropylene, ABS-resin or polyvinylchloride is interposed between the plate 1 and a frame 2, which is made of resin A. The three components are fused and united tightly, thus forming a base plate for an electrode. The heating temperature here should be below the melting point of the resin A but above that of the resin B. The resin B in this case may be an easily heat-sealable resin obtained by cross- linking with metallic irons molecular chains of a copolymer such as ethylene-acrylic acid, or ethylene-methacrylic acid.
