Title: Gas diffusion electrode of fuel cell
Inventor: KOSEKI KAZUO
IPC: H01M4/96
Filed: 1985-03-29
Abstract: PURPOSE:To continuously maintain steady electrode performance by forming a water repellent layer with the mixture of carbon having high water repellency and carbon having low water repellency. CONSTITUTION:The mixed powder of carbon having high water repellency and carbon having low water repellency is used in a water repellent layer 3 arranged on gas side of gas diffusion electrode of fuel cell. By forming high water repellent part and low water repellent part inside the water repellent layer 3 and on the surface of the gas side of the water repellent layer 3, water produced in high load operation is exhausted as water drops on the gas side through the low water repellent part. Peeling off of a catalyst layer 2 and the water repellent layer 3 and accumulation of water between layers 2 and 3 of a gas diffusion electrode are prevented. Therefore, the electrode can steadily be operated fro a long time.

Title: Dry immunity analyzing element
Inventor: SUDO YUKIO
IPC: G01N31/22
Filed: 1988-03-17
Abstract: PURPOSE:To obtain high analyzing sensitivity and accuracy in quantitative analysis, by a constitution wherein at least two water permeability layers form a unitary body, at least one of the water permeability layers is a porous layer, and components related to the reaction of antigen/antibody are added in the water permeability layers. CONSTITUTION:An element comprises at least two water permeability layers which form a unitary body. At least one of the water permeability layers is a porous layer. Components related to the reaction of antigen/antibody are added in the water permeability layers. One of the components related to the antigen/antibody is the labelled antigen. The other is the antibody for the non- labelled antigen and the labelled antigen. The labelled antigen is incorporated in the porous layer until the time when liquid to be checked comes to contact. The porous layer does not have the antibody substantially. The antibody is incorporated in the second water permeability layer which is located at a position separated remotely from the surface that receives liquid of the analyzing element from the porous layer. Said second layer does not incorporate the labelled antigen substantially. In this way, high analyzing sensitivity and the accuracy in quantitative analysis can be maintained.

Title: Engine controller for hydraulically driven vehicle
Inventor: TAKADA YOSHIKAZU
IPC: B60W10/10
Filed: 1980-05-16
Abstract: PURPOSE: To reduce fuel consumption and production of noise of an engine by associating the highest rotation of the engine with a control of a discharging amount from a hydraulic pump for travelling.  
     CONSTITUTION: Upon treadling a pedal 25 in order to cause a vehicle to travel, pressure oil is fed into a pump controller 7 by an amount in accordance with the depth of the treadling of the pedal 25, and a discharging amount from a hydraulic pump 4 is controlled in proportion to the pressure of the pressure oil and at the same time, a limit switch 28 operates to cause a magnet valve 19 to be energized so that compressed air is fed into a cylinder 14 to push up a bearing face (b) of a lever 10. A control lever 3 is thereby moved to a highest rotation position to thereby render the engine 1 into its highest rotation. On the contrary, if the pedal 25 is released, the limit switch is turned off and accordingly, if a medium rotation switch and a stopping switch are turned off, magnet valves 18, 19, 20 are not energized so that respective cylinders 13, 14, 16 contract themselves to thereby bring the lever 3 to its idle position. If the medium speed switch is turned off, the magnet valve 18 is energized to thereby bring the lever 3 to its medium speed rotation position.

Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce cost and to improve the reliability of an optical network having high performance by transmitting the signals with pulse width smaller than a specific percentage of the time that is decided by a signal transmission rate. SOLUTION: An optical modulator 12 is connected to an optical pulse generators 11 of transmitters A to C respectively and modulates an optical short pulse outputted from each generator 11. This modulation is performed so as to set the signal transmission rate at 100 [Mbps], for example, for each of transmitters A to C. Under this condition, each transmitting signal has a sufficient interval between signal pulses. Based on the transmission rate, a cycle T and the signal pulse width (t) are set at 10 [ns] and 100 [fs] respectively, and accordingly t/T is equal to 0.001%. In order words, the ratio is <=0.001%. Such signals are collectively transmitted to the receivers 14 of receivers D to F via a fiber 13a.  Thus, there is no collision among signals, and the signals are transmitted in a satisfactory conditions despite no adjustment being performed at all for the transmission timing among signals.

Title: Circulator
Inventor: ITOU TOSHIMASA
IPC: H01P1/387
Filed: 1978-05-31
Abstract: PURPOSE:To make a distribution constant-type circulator for great power small- size by coating the edge surface, at least, in the surface of a center conductor with a dielectric material. CONSTITUTION:Edge surface 4 of center conductor 2 which is placed on the circumference edge of ferrimagnetic material 3A is coated with dielectric material, which has a dielectric constant higher than air, so that edge surface 4 may be prevented from being exposed to air directly. A highest voltage is applied to this edge surface 4, and dielectric material 5 having a high dielectric strength displaces this part, and simultaneously, the electric field intensity of the surface of this part is weakened due to the high-dielectric constant material provided in edge surface 4. Since these function effects bringing discharge prevention are obtained multiplicatively, the distribution constant-type circulator for great power can be made small- size.

Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To restrict the increase of the sliding resistance at the time of pressurization by fitting a packing to a pressurizing side surface of a piston ring. SOLUTION: A packing 2 is fitted to a pressurizing side surface of a piston ring 1. An elastic body 5 is fitted to the inner peripheral surface of the piston ring 1 while displacing it in the pressurizing side 12 direction. The elastic body 5 is provided with a ventilation hole. The peripheral surface of the piston ring 1 is formed into a little tapered conical surface. With this structure, in the case of pressuring the pressurizing side 12, the packing 2 seals, and furthermore, since the elastic body 5 is provided with the ventilation hole, the inner peripheral surface of the piston ring 1 is not pressurized.  At the time of pressurization, the air pressure is applied to the piston ring 1 in the axial direction, and the repulsion of the packing 2 is increased by the pressurization, but the only part of the repulsion to be applied to a part near the cut surface influences the contact surface pressure. With this structure, quantity of increase of the friction force at the time of pressurization can be restricted to a remarkably small value.
