Title: Selection of semiconductor chip
Inventor: YONENAKA KAZUHISA
IPC: H01L21/68
Filed: 1987-07-23
Abstract: PURPOSE:To make it possible to remove a defective semiconductor chip in a short time by a method wherein an adhesive sheet, on which the adhesions of the positions of semiconductor chips are changed according to the semiconductor chips being nondefective or defective, is used at the time of a semiconductor wafer being divided into pieces. CONSTITUTION:A part, which corresponds to the position of a detective semiconductor chip on a semiconductor wafer, of a shutter 2 superposed on the side of the adhesive surface coated with an adhesive 11 of an adhesive sheet 1 is opened on the basis of data on the position of the defective semiconductor chip and ultraviolet light is irradiated from an ultraviolet lamp 3. The adhesive 11 of the adhesive surface, which is irradiated with the ultraviolet light, of the sheet 1 is cured and becomes an adhesive 12, whose adhesion is reduced. Then, the position of the semiconductor wafer 4 is conformed to the adhesive surface of the sheet 1 and the wafer is adhered. Then, by pushing the outer periphery of the sheet 1 from the side opposite to the adhesive surface using a hemispherical pushing jig 7, the defective semiconductor chip 6 located at a position, whose adhesion is reduced, falls from the sheet 1 and nondefective semiconductor chips 5 only are left on the sheet and are selected.

Title: Multibit bus wiring device and method
Inventor: SUZUKI SHINGO
IPC: H01L23/52
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To reduce the increase of the delay time caused by an inter-line and inter-layer coupling effects without increasing a layout area by turning on a switching element to make the multibit bus wirings conduct to each other and neutralizing the electric charge accumulated between bus wirings. SOLUTION: The CLK- leak signals are inputted to the NMOS path gates 104-0 to 104-2 as the connection inputs for a prescribed time set right after the data on each bit changed synchronously with the input of clocks CLK to the latch circuits D-F/F 100-0 to 100-3. Thus, the gates 104-0 to 104-2 are turned on for a short time. The metallic wires 102-0 to 102-3 conduct while the gates 104-0 to 104-2 are kept in the ON states. As a result, the electric charge generated by the capacitors C at the parts near the receivers 103-0 to 103-3 are neutralized between the adjacent bits via the gates 104-0 to 104-2 among those electric charge generated by the capacitors C and accumulated among the wires 102-0 to 102-3.

Title: Cassette adaptor
Inventor: MAEDA MASAYA
IPC: G11B15/665
Filed: 1981-11-19
Abstract: PURPOSE:To avoid the damage of a tape, by inhibiting the function of the shifting mechanism of a large cassette holding member when a storage detecting means detects that the tape is led out of a large cassette. CONSTITUTION:An up-down substrate 20 is at a lower position when a large cassette adaptor is connected to a portable VTR. Under such conditions, a tape 10a is led into the VTR by the lead-out pins 36 and 37 which are set at the opening part of a large cassette. Whether or not the pins 36 and 37 are set at the opening part is detected by a microswitch 161. When the fact that the tape 10 has been led out is detected, the conduction is secured to the 2nd ejection lock plunger 162. Then the rotation of a lock lever 33 is prevented by a hook pin 164. Therefore the ejection of the large cassette is inhibited even if an UP button 32 is pushed in this state. This can avoid the damage of the tape.

Abstract: PURPOSE:To collect dust entering a cartridge in a dust collecting part, to reduce cost and to improve the reliability of information in recording and reproducing by connecting the dust collecting part on the outer periphery of a disk containing part. CONSTITUTION:An optical disk cartridge 1 is provided with a discharge port 32 on part of the outer periphery, and a dust collecting air filter 3 is fitted on the end of the discharge port 32 in a direction that an arrow C shows so that the filter 3 can be taken out.
