摘要:
In a polymer electrolyte membrane type fuel cell employing a high polymer ion exchange membrane as an electrolyte, a fuel cells stack is produced at a low cost by easily constituting flow passages for a fuel gas, an oxidizing agent gas and a cooling water which have been conventionally constituted by a cutting process being hard to process and hard to reduce a cost. The fuel gas passage, the oxidizing agent gas flow passage and the cooling water flow passage are constructed by a combination of a diffuser constituted by a conductive porous body or a corrugated plate and an elastic gasket, whereby a cutting process is not required, and a number of parts can be reduced and an operating performance can be improved by integrally forming the gasket with the separator, so that a cost can be reduced.

A fuel cell device, wherein, after an output voltage from a main body of a fuel cell is converted using a converter, the relation between the resultant predetermined output voltage V 1 and an output voltage V 2 from a secondary battery is so set as to satisfy V 1>V 2. When, at the time of a sudden change of an external load, the output voltage V from the main body of the fuel cell becomes lower than a predetermined voltage V 3, an output to a charge controlling unit is stopped. When the output voltage V from the main body of the fuel cell is lowered even further and becomes lower than a predetermined voltage V 4, an output to an auxiliary device, which is necessary for driving the fuel cell device, is switched from the output from the converter to the output from the secondary battery.

A fuel cell apparatus of a compact size uses a hydrogen storage alloy, in which heat can be efficiently transmitted from fuel cell bodies to the hydrogen storage alloy. The fuel cell apparatus includes a plurality of fuel cell bodies, a hydrogen storage tank, a hydrogen supply device for supplying hydrogen to the fuel cell bodies from the hydrogen storage tank, an air feed device for supplying the air, supplying oxygen, a secondary battery, and a casing receiving the above components therein which casing has air intake ports and an air discharge port for the air feed device, and is formed as to enable the hydrogen storage tank to be introduced into and removed from the casing. The hydrogen storage tank is disposed on that side surface of each of at least one pair of fuel cell bodies, facing away from a cathode thereof, through a heat transmission device. With this construction, the energy of heat, generated by the fuel cell bodies, is efficiently transmitted to the hydrogen storage tank, and the stable supply of the hydrogen can be achieved, and the whole of the power system can be formed into a compact design.

Detecting means for detecting driving conditions of a vehicle such as engine load such as throttle opening, vehicle speed, gear position or gear ratio and so on and memory means for storing characteristics of the vehicle such as engine power characteristic, torque converter characteristic, fuel consumption rate characteristic and so on are provided. Driving shaft torques before and after gear shift, an estimating value of fuel consumption rate and a gear shift point of a transmission are calculated in real time to perform transmission control using the signals from said detecting means and the signals from said memory means. With the construction according to the present invention described above, an automatic transmission can be controlled in real time by calculating a gear shift point of the transmission in a short time through estimating the driving shaft torques before and after gear shift.

A thread chain back-tacker for an overlock sewing machine eliminates defective back-tacking. The back-tacker includes a thread chain cutter, an adjuster for adjusting the length of free thread chain after the end of back-tacking, a presser foot, an air nozzle, a thread drawing nozzle, a thread clamp cylinder, a nozzle swing cylinder, a nozzle pulling cylinder, a cylinder retainer coupling the nozzle swing cylinder and nozzle pulling cylinder together, a position adjuster bolt provided on the cylinder retainer for adjusting a stop position of the thread drawing nozzle, a speed setting/releasing unit, a venturi unit, an air breaking valve, and a solenoid for on-off operating the air breaking valve. The presser foot includes a presser body, a presser foot chain shield secured to the rear end of the presser body, and a presser foot stitch tongue secured to a central portion of the presser body. The presser foot stitch tongue has its back surface provided with a groove for guiding a thread chain and also has a top guide for guiding the thread chain into the groove. Not only is it possible to eliminate curling of the cloth end at the start of back-tacking and projection of the thread chain, but also it is possible to eliminate loosening of upper looper yarn. Satisfactory back-tacking results thus are obtainable, and needle breakage or the like is prevented.

Configurations for measuring sharing behavior and audience coverage for one or more users are provided. Some configurations can include the following components: an input processor (IP), a data processor (DP) and a visualization processor (VP). The IP extracts data from user logs or processes existing raw data, and prepares the data for the data processor. In one example, the IP transforms each user record into a structured file including time-ordered data corresponding to instances of information sharing activity, target users, and associated date-time(s) for the sharing activity. The DP takes the time-ordered data from the IP and performs statistical evaluations to classify and determine the audience coverage and sharing behavior. The VP receives processed data from the DP and generates different graphical visualizations (e.g., one or more graphs) based on the statistical analysis provided by the DP.
