Abstract: PROBLEM TO BE SOLVED: To suppress consumption of power supply battery. SOLUTION: When the terminal equipment is connected to a communication opposite party and a video conference is started, a CPU 10 receives image data to be sent from an image input device 20 and receives voice data to be sent from a voice input device 24 and uses a communication equipment 16 to send the image data and the voice data to the communication opposite party.

When the residual capacity of the battery 12 reaches a prescribed capacity or below, the power supply management equipment 14 informs it to the CPU 10 that the residual capacity of the battery 12 is too small.  The CPU 10 receiving the notice informs it to the communication opposite party via the communication equipment 16 that the transmission of the image data is stopped and only the voice data are sent at present. Then the CPU 1-0 gives a command to the power supply management equipment 14 to allow the equipment 14 to shut off supply of power to the image input device 20 and a camera 18.

Abstract: PURPOSE:To prepare a slime control agent capable of preventing mutual adhesion between microorganisms, a microorganism and a vessel wall or a microorganism and a floating material in water. CONSTITUTION:This slime control agent contains mono- or poly- oxypropyleneamine, e.g. a compound of formula I [(n) is 1 to 100], formula II [R is a 2 to 10C divalent alcohol residue; (a) and (b) are each 1 to 100] or formula III [R is a 2 to 10C trivalent alcohol residue; (p) and (q) are each 1 to 100; (r) 1 to 100; X is amino] as the active component. This compound has an effect of removing adhesion properties from a slime-forming microorganism and of dispersing the microorganism into water and, therefore, can prevent the microorganism from forming a microorganismic block or from adhering to the interface even when the microorganism grows. This slime control agent is used generally in an amount of 0.1 to 10000ppm, preferably 1 to 1000ppm based on the holding water quantity.

Title: Fault diagnostic device
Inventor: KOBAYASHI NAOYUKI
IPC: G06F9/44
Filed: 1989-12-29
Abstract: PURPOSE:To quickly and accurately perform the diagnosis of a fault by holding the alarm data to divide the data into groups and then estimating the candidate points for the factor of the fault to each group by means of an adverse searching method. CONSTITUTION:The measurement and non-measurement points included in a process 1 are shown by F1 - Fn and serve as the nodes forming a graph. An alarm data collection means 2 collects periodically the alarm data at each of those measurement and non-mesurement points of the process 1. Then the diagnostic processing is started when the difference is confirmed between the number of alarm data collected in the precedent time and that collected this time. A grouping means 3 divides those effective measurement points of the alarm data collected and held by the means 2 into groups. A fault factor estimating means 4 estimates the node having the coincidence between the number of effective points and the counted number of estimated codes in the same group as a candidate point for the factor of the fault to each group divided by the means 3 by means of an adverse searching method. These estimated candidate points are displayed on a diagnostic result display means 5.

Title: Electromagnetic clutch
Inventor: HAYASHI TOSHIHIRO
IPC: F16D27/112
Filed: 1992-12-24
Abstract: PURPOSE:To decrease any torque fluctuation by contracting either one volume of a first volume chamber and a second volume chamber while expanding the other volume according to the elastic deformation of a rubber hub. CONSTITUTION:When the relative rotation is generated between an inner hub 13 and an outer hub 12, either one volume in a first volume chamber 18a and a second volume chamber 18b is contracted, while the other volume is expanded because an elastic deformation in the rotational direction is generated on a rubber hub 14. At this time, viscous fluid sealed in a variable volume chamber 18 flows in the variable volume chamber 18 according to the contraction and expansion of the first volume chamber 18a and the second volume chamber 18b. This viscous fluid to flow in the variable volume chamber 18 passes through a communicating passage 18c when it is moved to the volume chamber side wherein the volume is expanded from that wherein the volume is contracted. At this time, flow resistance is produced according to the cross-sectional area of the communicating passage 18c and the viscosity of viscous fluid, this flow resistance acts as damping force. Thereby the torque fluctuation can be decreased.

Title: Signal changeover device
Inventor: SATO HIROSHI
IPC: H04B1/06
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To switch an external input signal received from an external equipment from the reception of a broadcast wave without modification to an existing receiver and without troublesome operation by the user. SOLUTION: An external input signal received by a signal input circuit 1 is fed to a modulation circuit 3, in which an oscillation output with the same frequency as the carrier of n-sets of broadcast waves and generated by a multi- spectrum oscillation circuit 2 is modulated by the external input signal. An amplifier circuit 4 amplifies an output of the modulation circuit 3 up to a prescribed level and gives the result to a switch circuit 5. An output of the switch circuit 5 is fed to a receiver. When the external equipment outputs a control signal, the switch circuit 5 replaces the antenna output detected by an antenna with the output of the amplifier circuit 4. Thus, even when receiver receives any broadcast wave, the received broadcast wave is replaced with the reception of the external input signal.

Title: Binder or adhesive for battery, and pressure sensitive adhesive tape or sheet
Inventor: TERAJIMA TADASHI
IPC: H01M10/05
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To lower the stresses to be applied to the structural material of an element while relaxing the stress without restricting the expansion of battery elements at the time of charge by lowering a fixing function of the binder or the adhesive or peeling it from the battery elements so that layers of the element are shrunken without practically melting or decomposing the binder or the adhesive in the battery electrolyte. SOLUTION: A condition that the binder or the like is not practically melted or decomposed in the electrolyte means that a weight reduction ratio by melting or decomposition in the condition that the binder contacts with the electrolyte or the binder is intruded with the electrolyte is less than 50%, desirably at 30-0%. In the case where the weight reduction ratio is at 50% or more, ratio of lowering of the electrolyte characteristic due to the diffusion of components of the binder in the electrolyte is increased, and as a result, battery characteristic is remarkably lowered. As a practical structural material of the binder or the adhesive, a material obtained by partially crosslinking a copolymer of an acrylic alkyl ester monomer such as acrylic acid butyl and a functional group contained monomer such as acrylic acid hydroxyethyl is used.

IPC: A47G9/10
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a pillow, by which pointillage effect can be applied to the occipital bone and the stress can be improved by providing a V-shaped projection on the surface of the pillow. SOLUTION: When finger-pressure is applied to the occipital bone of the head 4 toward the median line to compress the cerebral ventricle, the activity of the body tissue and body fluid can be promoted so as to relax the tension of the sympathetic nerve. The projecting and recessed parts of the pillow are made linear, the contact part with the head 4 is concentrated on the occipital bone, and the contact area is decreased. The shape of the pillow is V-shaped so that the direction of force for moving the head 4 downward is directed to the median line so as to apply finger-pressure to the occipital bone. At the time of using the pillow, when the head 4 is put on the V-shaped pillow part 1, the pressure is generated in the occipital bone by the weight of the head 4.  Further, when the head 4 is lowered, the occipital bone is strongly caught in the V-shape and the pressure is applied toward the median line by the force for moving the head downward, and pointillage effect is applied to the back- bone with suitable pressure.
