Title: Printing control system
Inventor: KOTANI YASUHIRO
IPC: B41J3/44
Filed: 1982-04-19
Abstract: PURPOSE:To make the printed result easy to observe, in a printing type desk top calculator with functional capability, by dividing lines when the sum of the digit number of a numerical value to be printed and the number of characters of function symbols exceeds the number of printable digits, and performing the printing. CONSTITUTION:A printer control circuit 4 judges whether the sum of the digits of a numerical value to be printed and the number of function symbols is within the printable digit number 16 or not. If the sum is within the 16 digits, the printing is performed in the same line. When the sum is 17 or more, at first, the contents of the X register of a memory 6 are transferred to a buffer PB7, then a printing code is transferred to a buffer PB. Therefore, only the numerical value is printed on one line. Thereafter the function symbols and the printing code are transferred to the printing buffer PB. The function symbols are printed on the next line. Thus, the printed result is made easy to observe, erroneous observation is not performed, and the device can be simplified.

Title: Semiconductor device
Inventor: AMANO TORU
IPC: H01L21/321
Filed: 1990-03-16
Abstract: PURPOSE:To prevent the short-circuit between the side end portion of a semiconductor chip and a lead wiring, by forming a dum between a bump and the periphery of the semiconductor chip, in a tape carrier structure. CONSTITUTION:In a carrier tape structure, the outer electrode of a semiconductor chip 5 is electrically connected to a lead wiring 3a via a bump 6. A dum 8 is formed between the bump 6 and the periphery of the semiconductor chip 5. Hence Au-Sn alloy wherein the bump 6 and the plated layer of the lead wiring 3a are fused by thermo-compression bonding can be reserved between the bump 6 and the dum 8, and it can be blocked for the fused Au-Sn alloy to flow out, on account of surface tension, to the side end portion of the semiconductor chip 5 along the stretching direction of the lead wiring 3a. Thereby the short-circuit between the lead wiring 3a and the semiconductor chip 5 can be prevented.

Filed: 1993-03-25
Abstract: PURPOSE:To obtain a synchronizing word detection system not requiring a high speed bit inverting clock whose circuit configuration is simplified and inexpensive by adopting the configuration such that the synchronizing word is detected while being limited to two-adjacent bit error. CONSTITUTION:In the detection system allowing a 2-bit error, when a bit error permission selection switch 6 selects the 2-bit error allowance mode, signals outputted from output terminals 1-3 of a decoder 42 of a 1-bit inversion circuit 4 are fed to three OR circuits of an adjacent bit mask circuit 32. In this case, even when a bit error is in existence in bits adjacent a bit inverted by the 1-bit inversion circuit 4, the output of the OR circuit corresponding to the adjacent bit mask circuit 32 goes to a logical 1 by the output of the decoder 42 and an AND condition of the AND circuit 32 is established. Then the AND circuit 32 provides the output of a synchronizing word detection signal of a logical level 1. The synchronizing word is detected by limiting the error to be the two-adjacent bit error.

Abstract: PROBLEM TO BE SOLVED: To easily expand a wire element wound in the shape of coil at a target position by inserting that wire element straightly into a catheter and constituting it so as to occupy the target position by being expanded when it is discharged from a catheter far end position to the target position. SOLUTION: An elastic wire is wound in the shape of coil and a coil wire 4 is formed while having a large diameter section 4a and a diameter section 4b which is made gradually narrow. The large diameter section 4a is expanded until it touches the wall of blood vessel 8, and the coil wire 4 is held at that position. When the coil wire 4 is inserted into the blood vessel 8, the narrow diameter part 4b is made flexible so as to enable guidance without damaging the blood vessel 8. The coil wire 4 is inserted almost straightly into the catheter and further extruded from the catheter to the target position in the blood vessel 8. At such a time, the large diameter part 4a expands, touches the inner wall of blood vessel 8 and holds that position. Thus, the coil wire can be easily expanded at the target position.
