Title: A method for preparing a clear royal jelly solution
Inventor: NOMURA JUNICHIRO
IPC: A61K35/64
Filed: 1992-09-08
Abstract: An inexpensive method for preparing a clear and stable royal jelly solution with a simple process is provided. A clear royal jelly solution is produced by preparing an aqueous royal jelly suspension, adding simultaneously or sequentially two or more types of protease that differ from each other with respect to action sites of a substrate, and maintaining the suspension to a temperature above room temperature, thereby solubilizing the insoluble matters by enzyme reaction.

Abstract: When converting an FSK output from an injection laser (2) into 1M (intensity modulation) by passage of the light through a Mach Zehnder interferometer (5), the conversion efficiency is regulated using a first feedback loop (7) to stablilise the laser's centre frequency at a half-intensity point on the spectral characteristic of the interferometer, and optionally a second loop (31) to regulate the frequency difference of the FSK so that the two FSK frequencies reside respectively at a maximum and a minimum of the characteristic. The first loop uses a low frequency modulation of the FSK frequency difference to derive its error control signal.

Abstract: Increasing the capacity of an existing lightwave transmission system can be accomplished by either increasing the bit rate or adding wavelength-multiplexed channels. Recent advances in erbium-doped fiber amplifier technology make the wavelength division multiplexed option particularly attractive. Unfortunately, because of nonuniform wavelength-dependent gain profile and saturation characteristic of erbium-doped fiber amplifiers, each channel of a wavelength-multiplexed system will experience a different optical gain which, in turn, can result in an excessive bit-error-rate performance in some channels. This invention is directed toward processing apparatus which selectively equalizes the optical gain or the optical signal-to-noise ratios of the channels of a wavelength-multiplexed optical transmission system. The output powers and the signal-to-noise ratios are selectively equalized by adjusting the optical input signal powers. With this invention, wavelength-multiplexed channels can be added to an existing optical fiber transmission system without requiring new optical components, upgrades or adjustments at intermediate amplifier sites.

Abstract: A two-dimensional ultrasonic transducer array (10) includes a plurality of transducer elements (12-18), with each element having a plurality of piezoelectric layers (120A, 120B and 120C). The transducer elements vary in transverse areas of radiating regions. The effect of the variations in transverse areas on the electrical impedances of the elements is at least partially offset by varying the specific impedance, i.e., impedance per unit area, of the transducer elements in the array. In a preferred embodiment, the specific impedance is varied by selecting the electrical arrangements of piezoelectric layers in each element according to the transverse area of the element. Series, parallel and series-parallel arrangements are employed. This impedance normalization improves the electrical connection of the transducer elements to driving circuitry (29A). In alternative embodiments, impedance normalization is achieved by varying element thicknesses, element materials and/or degrees of poling across the two-dimensional array.

Abstract: A linear motor is used to actuate an elevator door in response to a control signal for counteracting rotational torque caused by a variable-length moment arm (X1) about the center of gravity of the door by varying the magnitude of a linear force (F lin ) exerted on the door acting through a fixed-length moment arm (H cg ) about the center of gravity of the door for providing an opposing rotational torque, thereby counteracting the rotational torque caused by the normal force (F n ). The first and second rotational torques may be controlled to decrease and increase linearly as the door goes through its motion. In this way, the velocity profile varies in a curve similar to one side of the major axis of an ellipse. The normal force may be provided so as to levitate the door to reduce gravitational forces acting on door rollers. The control may be carried out in an open- or closed-looped fashion.

Abstract: The present invention provides a method in a data processing system for efficiently sending a data packet from a source node to a destination node. The data processing system includes a multi-segment network having at least two segments, wherein the source node and the destination node are located within in different segments. Communication of a data packet from one segment to another segment is provided by an agent node. The present invention generates a data packet at the source node within a first segment on the multi-segment node. The data packet includes a source address, a destination address, and data. The data packet is then transmitted within the first segment. Thereafter, the data packet is received within the first segment at an agent node. The data packet is examined to determine the destination address and then transmit it to the destination node within a second segment in the multi-segment network. The data packet is thereafter received at the destination node within the second segment and an echo packet is automatically transmitted from the destination node to the source node to indicate a successful reception of the data packet.
