摘要:
The disclosed control unit for a hybrid power generating system including a fuel cell and a storage battery backup includes an auxiliary controller for the fuel cell itself, and an output current controller for controlling the output current drawn from the fuel cell, whereby the storage battery can be charged for recovery within the shortest possible time to reach a target remaining charge capacity under charging conditions that do not cause deterioration of performance of the battery. The system is useful as the power supply in applications subject is sudden load fluctuations such as are encountered in a fork lift truck, for example.

An improved expansion valve (10) is disclosed for use with an air conditioning system (12) for an automobile. High pressure refrigerant flow is modulated through the valve by movement of a valve member (92) in response to the superheat of the low pressure refrigerant flow through a first passage (32) in the expansion valve. The low pressure refrigerant superheat is sensed by a power element (74) containing an adsorbent and gas which deflects a diaphragm (82) to a degree related to the superheat of the low pressure flow. The diaphragm acts on an annular seal retainer (100) to modulate the position of the valve member (92). A cupshaped high pressure seal (104) is provided between the valve member (92) and wall of the passage (54) in which the valve member moves to balance the forces on the valve member exerted by the high pressure refrigerant. The balanced valve member allows use of a compact power element, permitting the body (30) of the valve (10) to be formed of plastic.

A micro-displacement measuring apparatus using a semiconductor laser, comprises a compound resonator system containing the semiconductor laser, and a light detector receiving a light from said semiconductor laser. The compound resonator system is constructed such that a light from the semiconductor laser irradiates an object to be measured and the reflected light therefrom returns to the semiconductor laser, wherein the relationship between the reflectivity R.sub.f at the front facet of the semiconductor laser from which a laser light irradiates the object, and the reflectivity Rr at the rear facet of the semiconductor laser which is opposite the front facet is as follows: 0.1

An internal-reflection-interference semiconductor laser device comprising a first laser operation area ranging from one facet to the internal reflecting section and a second laser operation area ranging from the other facet to the internal reflecting section, wherein when the internal-cavity length l.sub.1 of the first laser operation area is shorter than the internal-cavity length l.sub.2 of the second laser operation area, the reflectivity R.sub.1 at the facet on the side of the first laser operation area is smaller than the reflectivity R.sub.2 at the facet on the side of the second laser operation area.

Finely-divided particulate bismuth oxide is produced by the steps of heating bismuth at 800.degree. C. or above in a first compartment of a sealed vessel divided into two compartments by a partition wall, the two compartments communicating with each other by a hole provided on the partition wall, feeding an inert gas such as nitrogen and argon into the first compartment so that the bismuth vapor formed by heating bismuth has a bismuth concentration of 0.1 to 0.5 g/liter, blowing air into the bismuth vapor introduced from the first compartment into the second compartment through the hole on the partition wall, permitting the air to mix with the bismuth vapor to form bismuth oxide and simultaneously cooling the thus formed bismuth oxide to 250.degree. to 300.degree. C., discharging by suction the bismuth oxide from the sealed vessel at a flow rate of 1 to 5 m/sec, and cooling the discharged bismuth oxide by supplying cooling air outside the sealed vessel.
摘要:
A diaphragm material for use in making loudspeakers comprising a base material of olefin resin and a reinforcement in the form of flaky material. The base material is 4-methylpentene polymer with or without the addition of another olefin resin. The flaky material is one or a mixture of flaky graphite, mica and talc.

A rear wall is detachably fitted at the rear of a body frame. A grinding wheel casing is also associated at the rear of the rear wall. A feeder wheel disposed on the front surface of the body frame and a rotatable grinding wheel provided within the grinding wheel casing are respectively rotated by a motor provided within the body frame. A cutter disposed opposite the feeder wheel cuts open a lid of a can rotated by the feeder wheel. The rotatable grinding wheel provided within the grinding wheel casing sharpens the edge of a knife inserted into the grinding wheel casing from a slit formed in a portion of the grinding wheel casing.
