Title: Binder for magnetic recording medium and magnetic recording medium
Inventor: HASHIMOTO HIROSHI
IPC: C09D175/04
Filed: 1993-03-25
Abstract: PURPOSE:To ensure high dispersibility and to improve preservability over a long period of time and durability by incorporating polyurethane using polyolefin polyol and polyisocyanate as principal starting materials and having three or more OH groups in one molecule into a binder. CONSTITUTION:When a binder is made of polyurethane which is a reactional product using polyol and polyisocyanate as principal starting materials, polyolefin polyol is used as the polyol and polyurethane having three or more OH groups in one molecule is produced. This polyurethane using polyolefin polyol ensures a wider spread of molecules and a higher degree of dispersion in an org. solvent as compared with polyurethane having polar bonds such as polyester or polycarbonate polyurethane. The polyolefin polyol preferably has OH groups in the hydrocarbon chain having 500-5,000mol.wt.

Title: Packet transfer regulation system using reference packet
Inventor: TOMINAGA SUSUMU
IPC: H04L12/70
Filed: 1990-03-19
Abstract: PURPOSE:To mitigate the congestion state of nodes and transmission lines by means of less processing by absorbing burst traffic in each node. CONSTITUTION:A reference packet transmission interval control means 104 controls a reference packet sending means 101 so as to expand the transmission interval of a reference packet 105 to be sent to the preceding packet exchange node. Thereby, the number of communication packet data 106 to be sent to a transmission line 107 in each unit time can be reduced. Therefore, the number of packet data 106 flowing from each preceding packet exchange node in each unit time is regulated. Consequently, a congestion state in a transmission line sending part or the like to the succeeding packet exchange node can be mitigated.

Title: Continuous hot rolling method
Inventor: MINAMIDA KATSUHIRO
IPC: B23K26/064
Filed: 1994-04-05
Abstract: PURPOSE:To reduce the variation in the transmission distance of a laser beam in cutting and joining stages by transmitting the laser beam with reflection mirrors which are moved in the rolling direction while synchronizing with the speed of a rolled stock. CONSTITUTION:By condensing the laser beam with the condensing mirror 5 through a beam convertor 10 and plural reflection mirrors 31-34 from a laser oscillator 2, the rolled stock is cut or welded. The movable reflection mirrors 32, 33 are moved in the same direction as the rolling direction of the rolled stock and at a half speed of that of the rolled stock. After (t) hours, the distaces are 12'=12+V/2Xt, 14'=14-V/2X-t (Where, the V is the speed of the hot rolled stock.) and 12+14=12'+14', so the transmission distance is not varied by the elapse of time. The distance between the reflection mirror 34 and the condensing mirror 5 is varied due to the difference in the area to be worked, but the variation is small. Since the variation of the transmission distance is small, convergent state is fixed and stable working is attained.

Title: Thermal recording material
Inventor: NOSAKA YOSHIFUMI
IPC: B41M5/26
Filed: 1993-03-25
Abstract: PURPOSE:To obtain a thermal recording material superior in color forming sensitivity and recording image shelf stability by providing a color-forming substance, a color-developer for coloring this substance an alkyl vinyl ether copolymer-modified polyvinyl alcohol resin of a specific average molecular weight, and a condensation naphthalene sulfonate on a substrate. CONSTITUTION:This is formed by providing a thermal color-forming layer containing a color-forming substance, a color-developer for said substance, an alkyl vinyl ether copolymer-modified polyvinyl alcohol resin (AVE modified PVA) of having an average molecular weight of 3000-25000, and a condensation naphthalene sulfonate on a substrate. If the AVE modified PVA in use has an average molecular weight less than 3000, a dispersion performance is deteriorated, and the thermal color-forming layer is also deteriorated in strength and binding power to the substrate. If more than 25000, a dispersion performance is deteriorated. The condensation naphthalene sulfonate typified by a compound shown by a formula improves a color forming sensitivity without impairing a shelf stability when being used in combination with the AVE modified PVA. In the formula, Z represents monovalent alkali metal atom or anmonium group, and (n) represents a repeat number.

Title: Manufacture of cadmium negative plate
Inventor: SUZUKI JUN
IPC: H01M4/26
Filed: 1988-03-21
Abstract: PURPOSE:To obtain a cadmium negative plate having high oxygen-gas absorbing capability by filling active material paste in a metal substrate having continuous three-dimensional pores, drying, and pressing in the thickness direction while the paste on the surface is peeling off. CONSTITUTION:A paste-state active material containing cadmium oxide or cadmium hydroxide is filled in a metal substrate having continuous pores such as foamed metal, and dried. The active material only on the surface of the filled plate is peeled off with a brush. The filled plate is pressed in the thickness direction and only the surface is made dense because of low mechanical strength. Current easily flows on the surface compared with the inside, and the active material on the surface is quickly, sharply converted into metallic cadmium to increase oxygen gas absorbing capability. Increase in internal pressure in a battery is retarded.

Abstract: PURPOSE: To easily deal with the demand for various power specifications of a user circuit by providing inside an interface circuit a plurality of power lines having different circuit constants corresponding to different source voltages. CONSTITUTION: A plurality of power lines 25, having resistance values from Ra, Rb,... up to Rn corresponding to source voltages varying from aV, bV,... up to nV, are provided inside an input interface circuit 6. In this case, the resistance values are set so that even when the source voltages vary from aV, bV,... up to nV, a current flowing through a photocoupler 21 or the like is almost constant. Therefore in the circuit 6, even if the source voltage of a power circuit 5 varies, the current flowing through the photocoupler 21 or the like is held constant by connection of the circuit 5 to a corresponding line 25, and replacement with other circuit components becomes unnecessary. Thus the need for replacement is eliminated, so the number of operations and the number of kinds of printed substrates can be reduced, small lot multi-production is made possible, and cost can be reduced.
