Title: Electromagnetic flow coupler
Inventor: TAKAGI TAKASHI
IPC: H02K44/04
Filed: 1986-05-13
Abstract: PURPOSE:To increase flow rate at electromagnetic pump side and to improve the pump efficiency and to eliminate influence of thermal stress strain, by a method wherein a duct section of generating side is as wide as a half of that of electromagnetic pump side or less and arranged in parallel, and a combination of both duct is floated in the outside duct. CONSTITUTION:Magnetic field is applied to a generating duct section I from arrow A direction and liquid metal flows in arrow B direction, thereby current is induced in arrow C direction. This current flows through a protective conduction material 24 and a conduction material 23 into a duct section II at electromagnetic pump side so that the liquid metal within the duct section II at electromagnetic pump side is driven in arrow F direction. On both sides of the duct section 1 is arranged the duct section 11, and if the former is as wide as a half of the latter or less, flow rate at electromagnetic pump side exceeds that at the generating duct section. Since the combined structure of the duct section I and the duct section 11 is floated in the outside duct I through the liquid metal, thermal strain produced by the temperature difference between the duct section I and the duct section II is not transmitted to the outside duct I.

Title: Air cell and manufacture thereof
Inventor: FUJII YASUO
IPC: A61H7/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To make the structure around an attaching part smaller and simpler, by making an extending direction in the midway of expanding from a contracted state to be shifted into an oblique direction to extend in a curve. SOLUTION: In opposite half areas of the outer periphery of an air cell 1, the forming number of bellows in one area is made larger than that of the other area, for instance, about five for one and about two for the other. Thereby the air cell 1 is made not rotation symmetric around the center axis, and, on the other hand, ones which do not make a round of the cell outer periphery are included in ridges in the convex side and the concave side in circumferential direction in the bellow in the area. Consequently, when air is supplied to the air cell 1 for extending, the extension of the area with small number of bellows is small to curve to the direction. Thereby, when both sides of a leg 11 supported by a concave part 10 of a massaging machine are clamped to be finger-pressed, the mounting position of the air cell is not restricted to make the structure smaller and simpler.

IPC: H02H7/26
Filed: 1987-05-06
Abstract: PURPOSE:To detect and discriminate a ground circuit easily and surely, by permitting the ground current of the current difference or more of each phase at the time of load unbalancing, to flow just for a short time, at the time of one-line ground. CONSTITUTION:A power transformer 51 is connected to a bus bar 56 via an incoming breaker 52, and via feed breaker 53, current is fed to a transformer 55 and a motor 59. When ground is generated on a power feeding circuit, then a ground voltage relay 62 is worked, and signal is transmitted to a controlling circuit 73 from the ground voltage relay 62. By the controlling circuit 73, a switch 72 is turned ON just once for a short time and is reset if ground voltage signal is gone. When the switch 72 is turned ON, then current flows through a resistor 71, and flows also to a ground point. By setting this current value to come to 3-interphase current difference or more due to the unbalancing of a load, ground troubles can be detected easily and surely.

Title: Manufacturing method of lead acid battery plate
Inventor: KATOU NAOYUKI
IPC: H01M4/21
Filed: 1981-07-15
Abstract: PURPOSE:To improve the strength of an active material and reduce its aging time when the active material is applied to a substrate and aged by performing the process under the atmosphere where CO2 exceeding its specified quantity is contained. CONSTITUTION:When a lead acid battery plate is formed through a process where an active material is applied to a substrate, and its aging and formation processes, the aging process is executed by containing dry ice or carbonic acid solution in the aging chamber, evaporating it, and forming the atmosphere where CO2 exceeding 10% is contained. Thus, H2O forms a catalyst by the existence of CO2 and PbCO2 is generated on the surface of a filling plate. The crystals are firmly coupled mutually and the active material becomes tight. As a result, the strength of the active material is increased remarkably and the active material can be prevented from slipping off. Besides, the aging time is reduced sharply and workability can be improved.

Abstract: PURPOSE:A human alpha-type interferon antigen having the C-terminal peptide of a novel human lymphoplastoid interferon as a hapten and consisting of a complex thereof with a carrier is given to a mammarian animal to obtain an antibody of high potency and sensitivity. CONSTITUTION:A novel peptide as a terminal peptide or its derivative of human lymphoplastoid interferon of the formula (R is H, H-Tyr) is used as a hapten to form a complex with a carrier such as equine serum albumen and the resultant human alpha-type interferon antigen is given to a mammarian animal to collect the antibody formed by the antigen-antibody reaction. The antigen has a very strong immunogenecity to give an antibody causing a specific reaction to the human alpha-type interferon. Usually it is obtained by effecting the reaction between the hapten and the carrier in the presence of a reagent binding the hapten with the carrier such as glyoxal in an aqueous or buffer solution of 7-10pH.

Title: Optical disk recorder
Inventor: IIMURA SHINICHIRO
IPC: G11B7/126
Filed: 1990-04-27
Abstract: PURPOSE:To prevent data from being erroneously written on an already recorded optical disk by detecting the peak value and the bottom value of a reproduced RF signal obtained from an optical head and recording data after confirming that data is not recorded on the optical disk. CONSTITUTION:A peak value P of the reproduced RF signal has the level changed by a volume 42 and is sent to the positive input terminal of a comparator 43. The peak value P from a peak holding circuit 40 is attenuated to a >(1-K)-fold value by the volume 42, and this value is compared with a bottom value B by the comparator 43. In the case of an already recorded optical disk, the former is larger than the latter, and the output of the comparator 43 goes to, for example, the high level. When the output of the comparator 43 is in the high level. a control circuit 50 judges an optical disk 1 to be already recorded and inhibits the write of data and calls user's attention by display or the like. A switch 33 is so controlled the it selects the output of a phase compensating circuit 32. Thus, double write of data is prevented.

Title: Level converting circuit
Inventor: SESHIMOTO AKIRA
IPC: H03K17/66
Filed: 1984-05-30
Abstract: PURPOSE:To attain a high-speed response with no increase of the current consumption for a level converting circuit which converts at a high speed a signal of a low level into a signal of a high level, by connecting a constant current source between a power supply and a collector of a driving transistor. CONSTITUTION:A constant current source 4 is connected between the collector of a transistor (TR)Q1 connected to a drive terminal 1 and a positive power supply +V. Thus a constant current given from the source 4 is allocated to the collector of the TRQ1 or the base of a TRQ3 in accordance with the ON/OFF actions of the TRQ1. In this case, the floating capacity of the TRQ1 or Q3 is charged by the constant current. As a result, the rise of the output voltage of an output terminal 2 is linear as shown by a dotted line of a figure (b) and also extremely fast compared with a conventional expotential function. The current of the source 4 is constant and can be controlled to the prescribed value. Therefore the current consumption can also be reduced.
