Title: Semiconductor device with redundant circuit
Inventor: NISHIMURA YASUMASA
IPC: H01L21/822
Filed: 1984-08-31
Abstract: PURPOSE:To shorten the test time of defective elements in wafer test, by a method wherein an identification circuit which identifies good elements and defective elements of each semiconductor device on wafers which is detected in the redundant circuit substitution process is attached. CONSTITUTION:A fuse 22 is newly added to distinguish good elements and defective elements when the redundant circuit substitution of a semiconductor device is carried out. The semiconductor device having the redundant property is inspected how desired functions are realized or not in the redundant circuit substitution process while the wafer processing, and the substitution is carried out if defective parts can be substituted by the redundant circuit of the semiconductor device 21. The function test is performed again after the substitution is performed, and if it is defective, or the substitution is impossible, a fuse 22 is cut. In the wafer test, the semiconductor device which is identified to be defective already in the redundant circuit substitution process can be evaluated in a few mili sec time by performing at first the pin contact test of a outer input terminal 3 having the fuse 22.

Title: Picture signal correlation decision and interpolation data preparing device
Inventor: SATO KOICHI
IPC: H04N5/14
Filed: 1989-07-17
Abstract: PURPOSE:To improve the quality of correlation decision by selecting an interpolation signal and replacing the contents of a correlation deciding signal when a direction to connect upper and lower picture signals having a correlation changes to a different direction. CONSTITUTION:For example, in an asterisk part S, even though it is decided that the correlation between picture signals A4 and B2 is strong in a decided result in the preceding picture element, it is decided that the correlation between picture signals A1 and B5 is strong in decision at this time. In this case, it means that the direction to connect the upper and lower picture signals having the correlation changes to a completely different direction. Since the possibility of erroneous decision is high in this case, the contents of the correlation deciding signal are forcibly replaced so that it can select the interpolation signal obtained from picture signals A3 and B3. Thus, the accurate correlation decision can be executed.

IPC: H04W88/06
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To make a frequency of using high speed communication services increased and to transmit information of a large capacity for a short time by utilizing service and communicating when the high speed communication services enter an available state within a specified time after a communication demand from a mobile terminal and/or the communication demand to the mobile terminal. SOLUTION: When a communication demand through second radio base station BSB2 occurs at a mobile terminal MS by a user operation or the like, a timer within a mobile terminal MS3 is started. If communication by way of the second radio base station BSB2 becomes possible until a timer value reaches a standby limit time, a communication demand is transmitted to a communication network through the second radio base station BSB2. When the timer value reaches the standby limit time, it is judged that the communication through the second radio base station BSB2 is impossible. In this case, it is possible to communication at low speed by being connected to a first radio base station BSA1.
