Title: Heat sensitive adhesive label
Inventor: HATA TETSUO
IPC: G09F3/10
Filed: 1994-03-03
Abstract: PURPOSE:To obtain a heat sensitive adhesive label ensuring easy sticking work and simple storage by forming an adhesive layer exhibiting adhesive property when heated and reducing its adhesive strength under an alkaline aq. soln., on the rear side of a substrate with a formed printed layer. CONSTITUTION:An adhesive layer 2 is formed on the entire rear side of a substrate 1. An adhesive used in the adhesive layer 2 is a delayed tack adhesive which does not exhibit adhesive property at an ordinary temp. but is activated at 50-150 deg.C, preferably 60-100 deg.C to exhibit tackiness and retains this tackiness for several hr to several days. When the adhesive comes in contact with an alkaline aq. soln., the adhesive strength is reduced by dissolution. The resultant heat sensitive adhesive label ensures easy sticking work, does not require releasing paper, etc., because of no adhesive property at an ordinary temp. and can be compactly stored. The label is easily peeled off by washing with the alkaline aq. soln. at >=60 deg.C.

Title: Shared resource management processing system
Inventor: KITADATE YOTARO
IPC: G06F15/16
Filed: 1987-02-17
Abstract: PURPOSE:To make a range in which an exclusive occupancy is generated as small as possible and also to make a main storage capacity comparatively small, by dividing and subdividing a common resources area and systematizing it to a tree shape, at the time of carrying forward a processing, while occupying the shared resources in dependently to each other. CONSTITUTION:As for nodes A-E of a range which contains a root A in a tree struc ture, for instance, shown as a tree part alpha in the figure, the possibility that they are used by following up a fact that they are occupied themselves or one of the subordinate nodes is occupied is high, therefore, they are managed by a fixed management table 5. That is, management information is always held in a form of 1-to-1 in accordance with separate node. On the other hand, as for nodes F-K of a range shown as a tree part beta in the figure, the frequency by which they are occupied is not so high, and when it is tried to hold the management information in a form of 1-to-1 in accor dance with a separate node, sometimes the capacity of a main storage 1 become large. Therefore, when a state that the nodes are occupied as the present problem is generated, they are registered temporarily on a management table 6 and managed. In such a way, the common resources can be managed effectively, while reducing the memory capacity.

Title: Nitriding process for metallic powder
Inventor: IMAGAWA HIROSHI
IPC: C01B21/072
Filed: 1985-02-22
Abstract: PURPOSE:To produce high-purity nitride powder having specific particle diameter, by irradiating laser beam locally to metallic powder in a nitrogen-containing gas atmosphere, thereby initiating the nitriding reaction. CONSTITUTION:The metallic powder 3 is charged to the feeder 2 at the upper part of the reactor 1, nitrogen gas is introduced through the inlet line 4 into the reactor 1, and the gas in the reactor 1 is exhausted through the exhaustion line 5. The metallic powder 3 in the feeder 2 is dropped in dispersed state by the vibrator 6 and the damper 7 attached to the feeder 2. At the same time, the falling metallic powder 3 is irradiated with CO2 laser beam 8 incident through the window 9 into the reactor 1 to induce the nitriding reaction of the metallic powder 3 by the local heating. The nitrided powder 3 is collected in the stocker 10, and heated at 1,400-1,600 deg.C in nitrogen gas atmosphere. The metallic powder is preferably powder of Al, Si, B, Ti, etc., and the particle diameter is preferably about 0.1-10mu. Highly pure nitride powder having specific particle diameter can be produced by this process without causing the fusion of the particles or the adhesion of the particle to the reaction vessel 1.

Title: Recycling method of positive electrode for lithium ion secondary battery
Inventor: SHIBATA YASUFUMI
IPC: H01M4/485
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To recycle a positive electrode by recrystallizing the positive electrode changed to an amorphous material by its deterioration in a process to cool it at a specific speed after baking. SOLUTION: An initially crystallized positive electrode active material is gradually changed to an amorphous state over aging, due to a defect produced in a crystalline by removal of a lithium atom at the time of charging and a physical force applied to the crystal by the lithium atom moving inward from a negative electrode. In the case the condition of a positive electrode active material of lithium manganate is changed to an amorphous condition, a capacity ratio almost equivalent to that in the initial condition can be obtained by cooling it at a speed of 0.5-1 deg.C/minute after baking it in a temperature of 700-800 deg.C for 30-40 hours. The crystallite structure is judged to be almost brought back to the initial condition by a measurement of a peak and a grating constant in an X-ray analysis.  Even if the positive electrode active material is lithium cobaltate or lithium nickelate, the initial condition can be reproduced by selecting the most suitable baking condition and cooling speed.

IPC: G11B20/10
Filed: 1981-03-09
Abstract: PURPOSE:To reproduce digital information accurately, by avoiding the digital information having comparatively longer inverting period from being fallen down to zero level for the differentiating signal of the information. CONSTITUTION:A detection signal S'E of digital information via a differentiation circuit 4 is inputted to an input section of the 1st and 2nd level comparators 6 and 7. The comparator 6 synchronizes when the input signal S'E is below or above a reference level (a) and outputs the 1st digital signal SF, and similarly the 2nd digital signal SG is outputted. An AND gate 8 and an OR gate 9 output signals SH and SI respectively. The digital signal SH is inputted to an RS type FF10 via a set terminal S and the digital signal SJ is inputted via a reset terminal R. Thus, a digital signal SK corresponding to the digital information recorded on a recording medium is outputted. Thus, the digital information can be reproduced accurately.

Title: Production of ceramic superconducting material
Inventor: NATORI EIJI
IPC: C04B35/00
Filed: 1989-02-14
Abstract: PURPOSE:To obtain the superconducting material having a high critical current density and capable of being used without any restriction by adding Pb or PbO powder to the powder of a layer-structure Tl-M-Cu-O ceramic, compression- molding the mixture, sintering, and heat-treating the molded product. CONSTITUTION:The Tl-M-Cu-O-based or Tl-Pb-M-Cu-O ceramic superconducting material is produced mainly by the following processes (M is alkaline-earth metals). Namely, the powder of a layer-structure Tl-M-Cu-O ceramic is formed, Pb or PbO powder is added to the ceramic powder, the mixture is compression- molded, and the molded product is sintered and heat-treated. By this process, the crystal orientation can be controlled even when a material having high anisotropy is used, and hence the critical current density is drastically improved. Since the Pb to be used as an orientation assistant contains no impurities and is the superconducting material constituting element, superconductivity is not inhibited by the Pb. Consequently, the ceramic superconducting material is used without any restriction.

Abstract: PROBLEM TO BE SOLVED: To save a required quantity of atmospheric gas, and reduce the running cost, by providing a low-temperature room with an electromagnetic exhaust valve which operates by a furnace pressure sensor, and discharging atmospheric gas within the low-temperature room. SOLUTION: In a normal condition, a gas supply valve 9 is opened to supply a high-temperature room 1 with atmospheric gas, and also its one part is discharged from an exhaust pipe 16 through a door room 14, and the other flows to the low-temperature room 4. Moreover, when shifting the metallic product 2 within the high-temperature room 1 by opening an opening/closing valve 6, or also when shifting the metallic product 2 within the low-temperature room 4 to a vacuum virgin room 21 on an extraction side, an electromagnetic exhaust valve 33 is opened or closed by the command from a controller 31. Hereby, similar to the case of the room 14, the furnace can prevent outside air from entering the door room 24 even if the quantity of atmospheric gas is small.  That is, it materializes not only in the relation between the high-temperature room and the door room 14 but also in the relation between the high- temperature room 1 and the low-temperature room 4 or the door room 24.
