In construction of a liquid crystal display including an alignment film and generally used for video display panels such as television sets, the orientation wafer is given in the form of a porous alumina layer. Substantially vertical molecular orientation is resulted from penetration of liquid crystal molecules into pores in the alignment film. Optical application of rubbing process in production enables free adjustment of the value of pretilt angle. Good reproduction and stability is assured even in the case of large fields of vision.

A pre-impregnation has a ribbon-shaped tow of reinforcing fibers and a ribbon of thermoplastic resin laminated on the ribbon-shaped tow and fixed thereto at intervals, and the thermoplastic resin is allowed to uniformly impregnate into the ribbon-shaped tow under heat application so that a void does not take place in the ribbon-shaped tow.

Herein disclosed is a data communication system in which a plurality of node equipments are linked to a common signal transmission line so that the data may be communicated between the respective node equipments. The data communication system is characterized: in that at least one of the node equipments includes means for generating and transmitting repeatedly for a predetermined period the channel which contains a data transmission bit and a validity bit for the former bit; and in that each of the node equipments linked to the common signal transmission line partly sends out the data through said channel and partly makes the validity indicating bit indicate an invalid state, when the speed of said data is so slower than the predetermined period of said channel that the data to be sent out for the predetermined period are out of time thereby to make it possible to effect the data transmission at an arbitrary speed shorter than said predetermined period.Herein also disclosed is a data communication system in which a plurality of node equipments are jointed by a common transmission loop line and in which the information of multiple channels is repeatedly transmitted for a predetermined period to said transmission loop line so that the channel information may be sent and received between terminal equipments linked to said node equipments. The data communication system is characterized in that an identical pattern for synchronization is inserted into and transmitted by the plural head channels of each period so that the synchronization is effected at each of said node equipments by detecting the synchronizing pattern received by means of a detecting circuit.

A sound absorbing structure is constituted of a housing having a hollow portion and an opening and a vibration member composed of a board or diaphragm. The vibration member is a square-shaped material having elasticity composed of a synthetic resin and is bonded to the opening of the housing, thus forming an air layer closed inside the sound absorbing structure by the housing and the vibration member. In the sound absorbing structure, when the lateral/longitudinal dimensions of the air layer and characteristics of the vibration member (e.g. a Young's modulus, thickness, and Poisson's ratio) are set such that the fundamental frequency of a vibration occurring in a bending system falls within 5% and 65% of the resonance frequency of a spring-mass system, a vibration mode having a large amplitude occurs in a frequency band lower than the resonance frequency of the spring-mass system, this improving the sound absorption coefficient.

A method for manufacturing a probe unit includes: (a) preparing a substrate; (b) forming a hollow part in the substrate; (c) forming a sacrificial layer that buries the hollow part on the substrate; (d) forming a first layer on the substrate, wherein one end of the first layer is positioned on the sacrificial layer; (e) forming a second layer on the first layer at least excepting the one end; and (f) removing the sacrificial layer.

In order to provide a sound-absorbing body which has both a thin thickness and improved sound-absorption characteristics with regard to a low tone range sounds, the sound-absorbing body (1) includes: an organic hybrid sheet (2) constituted from an organic low-molecular material which is spread in a matrix polymer; and a gastight air cell (3) which is closely provided at a backside (2a) of the organic hybrid sheet, wherein the organic hybrid sheet indicates both a sound-absorption peak of a random incidence sound-absorption coefficient at a frequency band of 400 Hz or lower and another sound-absorption peak when the organic hybrid sheet is vibrated by applying air vibration caused by sound, because of adhering the organic hybrid sheet to the gastight air cell.

摘要:
In a loop bus network system where a plurality of processors are connected to a unidirectional loop bus and each of the processors generates a transmission message with a level number which designates the bus use priority of the message, each of node processors, in which message transmission request is generated, transmits to the loop bus a bus control data including a level number of the message generated therewithin and a data which represents the bus use priority assigned to each node processor for that level number. Each of the node processors compares the bus control data transmitted therefrom to a succeeding node with a control data received from a preceding node and then transmits only the larger data of the compared two data, thereby to ascertain that only one bus control data propagates around the loop and a loop bus use priority is assigned to one of the node processors that has generated the above-mentioned one bus control data.
摘要:
A probe unit comprises a substrate and a lead formed on the substrate and having a tip part projecting from an edge of the substrate and contacting to an electrode of a sample, and a thick part of which thickness is thicker than the tip part. The probe unit can make continuity with a sample firmly with a proper contact pressure while lowering electrical resistance of leads.

An air supplying apparatus may include, but is not limited to, a pump, a motor, a housing, and an intake unit. The motor drives the pump. The housing provides a chamber that contains the pump and the motor. The intake unit supplies an air to the chamber. The intake unit may include, but is not limited to, first and second portions. The first portion communicates with the atmosphere outside the apparatus. The second portion is coupled to the housing. The second portion communicates with the chamber. The second portion is configured to blow the air to the motor.
