摘要:
A flight velocity detection system using a truncated pyramid-shape multi-e Pitot probe in which an extreme end portion has a truncated pyramid-shape, a cylindrical hole is provided at the apex thereof, a total pressure tube of a smaller diameter than that of the cylindrical hole is secured at a position by a predetermined length determined by a relationship with the diameter of the cylindrical hole from the extreme end of the cylindrical hole, and groups of pressure holes comprised of a plurality of pressure holes are arranged in each of the truncated pyramid surfaces of the truncated pyramid shape. Items of pressure information detected by the probe are input into a velocity vector processor to convert them into electric signals, and signals are processed using pressure coefficients of the holes of the probe with respect to the velocity vector stored in advance in the velocity vector processor to calculate flight velocity vector (V, .alpha., .beta.) with respect to the probe axis from the pressure information and air density.

An issue of reducing a product manufacture unit cost exists in wireless IC chips which are required to be disposable because the wireless IC chips circulate in a massive scale and require a very high collection cost. It is possible to increase the communication distance of a wireless IC chip with an on-chip antenna simply contrived for reduction of the production unit cost by increasing the size of the antenna mounted on a wireless IC chip or by increasing the output power of a reader as in a conventional way. However, because of the circumstances of the applications used and the read accuracy of the reader, the antenna cannot be mounted on a very small chip in an in-chip antenna form. When an AC magnetic field is applied to an on-chip antenna from outside, eddy current is produced in principle because the semiconductor substrate is conductive. It has been fount that the thickness of the substrate can be used as a design parameter because of the eddy current. Based on this finding, according to the invention, the thickness of the substrate is decreased to reduce or eliminate the energy loss due to the eddy current to utilize the electromagnetic wave energy for the semiconductor circuit operation as originally designed. With the thickness reduction, it is possible to increase the communication distance by preventing ineffective absorption of energy and thereby increasing the current flowing through the on-chip antenna.

摘要:
A reader reads electronic tag data and a CRC code from an electronic tag and detects whether the electronic tag data has been received correctly, by using the CRC code. The CRC code is generated from reader data and electronic tag data stored in the reader and an error detection is performed by using the reader data, so that the error detection is performed simultaneously, and it is possible to selectively read out only the electronic tag data from the electronic tag correlated with the reader data.

A non-contact identification semiconductor device is provided with a semiconductor chip including a receiving circuit that receives an inquiry to the non-contact identification semiconductor device, a memory that stores identification information of multiple bits and a sending circuit that sends the identification information. An antenna coupled to said semiconductor chip receives the identification information from said semiconductor chip and transmits the identification information outside of said non-contact semiconductor. The long side length of the semiconductor chip is not greater than 0.5 mm in plane dimension, and the identification information is stored by a pattern printed by an electron beam.

The existing IC cards have a disadvantage of difficulty of mass production because an IC chip is supplied on a substrate one at a time. The present invention provides a method of manufacturing by placing a positioning jig having a plurality of openings each of which has a size fit with a semiconductor device, providing a plurality of semiconductor devices on said jig to house the devices into the openings, and fixing on a substrate then cutting the substrate to provide independent electronic devices. When the semiconductor device is in a form of chip, a support member attached to the chip will facilitate the handling of chips.
摘要:
This Application is intended to provide a method for effectively protecting paper or film-form media against forgery. This can be achieved by, for example, embedding in a paper or film-form medium a thin semiconductor chip up to 0.5 mm square, equipped with an antenna, and characterized in that the side walls of the semiconductor chip are formed using oxide films, and in that multiple such semiconductor chips are separated by etching. Limiting the size of these semiconductor chips to 0.5 mm or less enables improvement against bending and concentrated loads, and separating the semiconductor chips by etching results in semiconductor chips free from cracking and breakage. Also, the oxide films constituting the side walls of the semiconductor chips prevents short-circuiting at edges during connection to the respective antennas. Thus, simplified processes can be adopted.
