Title: Electroplating method
Inventor: SUZUKI TERUO
IPC: C25D5/00
Filed: 1980-12-17
Abstract: PURPOSE: To obtain good plating by a method wherein, in strong acidic plating bath, a soluble and an insoluble electrode plates are simultaneously used as an anode while an area ratio therebetween is adjusted to keep a pH during electrolysis constant.  
     CONSTITUTION: When a soluble electrode plate is used as an anode in a strong acidic plating bath, pH is raised and, reversely, when an insoluble electrode plate is used as the anode, the pH is lowered rapidly. Then, both electrodes are used together as well as, in due consideration of anode current efficiency of the soluble electrode plate, an area ratio of both electrode plates is adjusted. For example, in a plating liquid comprising cobalt sulfate, ferrous sulfate, sodium boron fluoride, sodium saccharine, the area ratio of the soluble electrode plate (Co) and the insoluble electrode plate (C) in the anode is adjusted to about 1:1.2. Further, when electroplating is carried out under such a condition that a ratio of anode: cathode is about 1:1 and pH is about 2.0, pH is held at about 2.02 and is scarcely changed.

Title: Scroll type compressor
Inventor: ASANO HIDEO
IPC: F04C23/00
Filed: 1985-08-15
Abstract: PURPOSE:To make it possible to compress two different lines of gases of different pressures efficiently with a single compressor by dividing a suction chamber formed around both scroll members into two chambers by means of a fixed and movable partition walls and connecting a suction pipe to each chamber. CONSTITUTION:A fixed partition wall 32 is arranged on the periphery of a fixed scroll 14 while a movable partition wall 33 forced by a spring contacts on the periphery of a turning scroll 15. This makes a suction chamber around the both scrolls 14 and 15 divided into two chambers. A first suction port 9 and a second suction port 11 respectively connected to separate fluid lines open to the respective chambers. As a result, since gasses of different pressures are mixed in the last stage of compression stroke and discharged at a some pressure, two lines of gasses can be compressed efficiently with a single compressor.

Title: Magnetic recording medium and its production
Inventor: AOSHIMA KENICHI
IPC: G11B5/82
Filed: 1994-07-29
Abstract: PURPOSE:To improve recording characteristics as well as to prevent the generation of spike noise by forming beltlike antiferromagnetic layers in the form of concentric circles at intervals on a backing layer. CONSTITUTION:A backing layer 22 of a soft magnetic substance having a prescribed thickness is formed on a disk substrate 21 made of a discoid Al sheet. Grooves 23a-23c each having about 1mum width and 20mum depth are formed in the layer 22 at about 2mum intervals and antiferromagnetic layers 24a-24c are embedded in the grooves 23a-23c. A magnetic recording layer 25 made of a perpendicularly magnetized film of CoCrTa, etc., is then formed so as to coat the layers 24a-24c and the backing layer 22. Regions with the formed layers 24a-24c become guard band regions. Since only the guard band regions exist between the magnetic recording layer 25 as a recording region and the backing layer 22, reproduction output is increased.

Title: Nonvolatile semiconductor storage device
Inventor: NOZOE ATSUSHI
IPC: G11C16/02
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To efficiently make uniform the number of rewriting without increases in chip area and part item number by utilizing a sense latch circuit as a buffer. SOLUTION: Memory arrays 10A and 10B are respectively arranged in the positive and negative logical output sides of a sense latch circuit 11 and data lines DL are connected thereto. When replacing data with another, data is transferred from the memory array connected to the positive logical output to the memory array connected to the negative logical output or vice versa. Thus, since data is replaced with another without providing any buffers not only outside but also inside a chip, the number of rewriting is made uniform without increasing a chip area or the number of part items. Also, data is replaced with another within a short time because data is not read to the outside and thus rewriting efficiency is increased.
