Title: Semiconductor storage device having built-in testing function
Inventor: HISAIE SHIGEHIRO
IPC: G11C29/50
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To reduce the chip area of a semiconductor storage device having a self-testing function by realizing a built-in self-testing function with a simple circuit configuration by constituting a sequencer device which controls the operations of the built-in self-testing section of a sequential circuit. SOLUTION: A sequencer circuit 49 which controls the operations of a built-in self-testing BIST section 23a is constituted of a sequential circuit. When a test start signal is inputted from the outside through an ENTRY terminal 43, a test pattern is 'data written' in a memory cell 19. Then 'disturb processing' is performed by using all bits in the memory cell 19 as base cells. Thereafter, data are read out from the memory cell 19 and 'compared' with the test pattern. The compared results are outputted from an ERROR terminal 44. Thus a semiconductor storage device having a built-in self-testing circuit can be realized in a chip having a small area.

Title: Manufacture of resin package
Inventor: KAJIWARA KAZUKUNI
IPC: B29C45/26
Filed: 1987-12-15
Abstract: PURPOSE:To prevent an electronic parts mounting surface from generating resin flashes, by a method wherein a cavity and a circumferential part of the electronic parts mounting surface are stuck close to each other forcibly with a vacuum. CONSTITUTION:Resin is filled into a space formed of cavities 1a, 1b through a resin filling hole 3. Insert parts or an element are mounted on an electronic parts mounting part 15 by opening the cavities 1a, 1b after cure of the resin. Only a circumferential part 17 of the electronic parts mounting surface 16 comes into contact with the cavity 1a even if an undulation exists to some extent on the electronic parts mounting part 15. Therefore, when the electronic parts mounting surface 16 is sucked with a vacuum, the circumferential part 17 is stuck close completely to the cavity 1a easily. Therefore, resin flashes are not generated on the electronic parts mounting surface 16.

Title: Joint made of shape memory alloy
Inventor: AMANO KAZUO
IPC: G21C17/10
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of fastening of a joint which may be caused by thermal cycle by bilaterally dividing a liner structure, forming a groove on a piping to be connected, and pressurizing the liners by means of force generated at the time of deformation of shape memory alloy for connection of the joint. SOLUTION: Shape memory alloy drivers 1a, 1b have such characteristics that they are reduced in diameters by heating. A tapered portion 3 and circumferential projections 4a, 4b are formed on an inner surface of a liner 2. After completing fastening, the liner 2 is pressurized into a groove 10 of a piping 8b. Restriction force due to thermal stress when temperature cycle is generated is received by portion being the liner 2 pressed into the groove of the piping 8b. This portion is not loosened because it has a surface area equivalent to the shape memory alloy driver 1b. The shape memory alloy driver 1a is fastened with its upper portion contact with the tapered portion 3 being much reduced in diameter, due to a structure where the tapered portion is formed on an end inner surface of the liner 2.

Title: Analog-digital mixed arithmetic ic
Inventor: HAYASHI SHUNSUKE
IPC: H03M3/02
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution of a digital arithmetic part by converting plural analog input signals into the bit streams via a sigma-delta modulator, calculating the analog input signals in a bit stream state via a bit stream computing element, and converting the arithmetic result into the analog signals to output them via a sigma-delta demodulator. SOLUTION: A sigma-delta modulator A-MOD modulates an input signal A or B into a bit stream and changes its output between 0 and 100% according to the analog value of one-existence ratio of the bit stream. The output of a bit stream computing element BSO which inputs the signals A and B is demodulated by a sigma-delta demodulator A-DEMOD and outputted as an analog signal. The output of the BSO is also demodulated by the A-DEMOD and outputted as the digital data having the necessary bit width. Thus, the data can be processed with high accuracy by a small number of logic circuits and sigma-delta demodulators.
