摘要:
In a communications system having a plurality of stations interconnected by a two-line circuit, in which the two-line circuit consists of a data bus circuit for transmitting a series of data bits between at least one sending station and at least one receiving station of the plurality of stations and a clock bus circuit for transmitting clock signals in synchronism with each of the data bits; the data bus circuit sends a signal or a command requesting the receiving station to enter a standby or an execute state after taking in data supplied, while a logic value on the clock bus circuit is fixed. In more detail, the sending station transmits signals to make at least one of the receiving stations enter the standby state after taking in data and then sends data to another receiving station, after which the sending station sends a signal or command to make both the first and second receiving stations simultaneously enter the execute state. The signal or command requesting the standby or execute state is added at the end of a data packet containing a series of data. The data packet includes data to be transferred to the receiving station and an address of the receiving station.

An object of this invention is to provide an acrylonitrile based composite fiber having a new feeling different from that of an ordinary cellulose acetate fiber, cellulose fiber and acrylic fiber, excellent spinability, fiber properties and process ability of yarn spinning, and excellent functions, in particular, a deodorizing function and a moisture absorbing and retaining property.The composite fiber is comprised of 10 to 40% by weight of cellulose acetate and/or cellulose and 60 to 90% by weight of an acrylonitrile based polymer, and has a structure with the cellulose acetate and/or cellulose forming an island component in a cross section perpendicular to a fiber axis and the acrylonitrile based polymer forming a sea component. Preferably, the cellulose acetate and/or cellulose as the island component communicate with another island component in the fiber axis direction, a vacant hole is provided inside the fiber, or a ratio of the longest diameter and the shortest diameter of the fiber cross section is 2 or less, and 5 or more recess parts of 0.3 μm or more and 3 μm or less width and 0.3 μm or more and 3 μm or less depth are provided in a fiber cross section outer circumferential part. Further preferably, by applying a heat treatment under alkali in a production stage, the moisture absorbing and retaining property can be improved.
摘要:
A liquid crystal display device in which light from a light source enters a liquid crystal panel and exits therefrom for projection of an image and includes a heat conducting member and a cooling unit. The heat conducting member is contacted with at least one of a light incident surface and a light outgoing surface of the liquid crystal panel, is light-transmissive, and has a larger area than a light transmitting area of the liquid crystal panel. The cooling jacket, which comprises a flow channel for a cooling medium in its inside, is provided around the heat conducting member so that the flow channel exists only outside of the light transmitting area in a surface direction of the liquid crystal panel.
摘要:
The present invention provides a liquid crystal display device and a liquid crystal cooling unit, which are reduced in noise and have high cooling capability, and in which air is not directly blown on a liquid crystal panel module or a polarizing plate. A cooling jacket having an internal flow channel is formed by being adhered to a periphery of a light-transmissive, highly heat-conducting sapphire plate larger than a light transmitting area to which a polarizing film is applied or attached, by means of a highly heat-conducting adhesive. A liquid crystal cooling unit is formed by clamping the liquid crystal panel module by inserting a light-transmissive, highly heat-conducting substance. Further, the liquid crystal panel module and the polarizing film are cooled by circulating a cooling medium in the internal flow channel of the cooling jacket.

The carbon fiber precursor fiber bundle of the present invention is an acrylonitrile-based fiber bundle wherein the ratio of the length and width of the fiber cross section of a monofilament (length/width) is 1.05 to 1.6, and the amount of Si measured by ICP (Inductively Coupled Plasma) atomic emission spectrometry is in the range of 500 to 4,000 ppm. This type of carbon fiber precursor fiber bundle has a high compactness, and the carbonizing processing ability is good. Furthermore, for the carbon fiber bundle which is to obtained hereafter, the resin impregnating ability and tow spreading ability are good, the strength increases, and it has bulkiness. Furthermore, the carbon fiber precursor fiber bundle of the present invention is an acrylonitrile-based fiber bundle wherein the liquid content ratio HW is 40 wt. % or more and less than 60 wt. %. The carbon fiber bundle obtained from this type of carbon fiber precursor fiber bundle improves the bulkiness and is superior in resin impregnating ability, tow spreading ability, and covering ability when made into cloth.

摘要:
A floppy disk in which the binder for fixing a magnetic substance in the recording layer of the magnetic disk is a polyester polyurethane and the liner of the jacket contains an acrylic fiber and in addition a fiber treating agent having a surface tension in a specific range. The floppy disk is excellent in workability, can be prepared in high yields because the number of dusts generated upon its preparation is small, and also is excellent in the permanence of recording performance.
