CONSTITUTION:A silicon dioxide film 1 is formed on the surface of a semiconductor substrate 2; the silicon dioxide film 1 is patterned by using a mask material 3; ions Of arsenic or phosphorus are implanted. After that, a part 4, at said silicon dioxide film 1, where the ions of arsenic or phosphorus have been implanted, is wet-etched; the silicon dioxide film 1 is removed. For example, the silicon dioxide film 1 is formed on the semiconductor substrate 2 by a thermal oxidation method; only a part where a contact hole is to be made is exposed, while the remaining part is covered with the mask, material 3; the ions of arsenic are implanted in such a way that they can reach the semiconductor substrate 2. Then, after the contact hole has been made by wet-etching the silicon dioxide film 1 by using a solution of buffered hydrofluoric acid or the like, a material wiring part 5 is formed by evaporating a metal or the like.

IPC: H01L27/15
Filed: 1990-10-31
Abstract: PURPOSE:To obtain an optoelectronic element of high performance by a method wherein a diffraction grating is arranged on a path of an electron wave, and a high speed switching is executed taking advantage of the wavelength of an electron wave or the diffraction condition difference determined by the level of a potential which forms a diffraction grating.

Title: Dummy flexible disk
Inventor: OSAKI SATORU
IPC: G06K19/07
Filed: 1990-11-01
Abstract: PURPOSE:To remarkably reduce for a time required for data readout by controlling the delivery of data read from read-only memory to a flexible disk via a head for data transmission. CONSTITUTION:An address control part 4 receiving the information of address delivery start sends a generated address to an IC-ROM 5. The ROM 5 reads out recorded data by a received address. Read out data is sent to a data transmission head 3, and is sent from the head 3 to a flexible disk drive. In such a case, a synchronism control part 1 reads the circulating state of a dummy disk 6 by an index hole 61, and issues an instruction to read out the next data to the control part 4. The control part 4 adds '1' on the address generated last time by the instruction, and sends it to the IC-ROM 5. Thereby, it is possible to read out large amount of data without performing seek after a readout operation is started.

Title: Fastening device of rail
Inventor: KIMURA MINORU
IPC: E01B9/28
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent a rail from laterally shifting and securely keep the electrically insulating condition at the insulative joint, by integrally forming a horizontal and nearly cylindrical pillow part meeting the upper face of a sleeper at the lower edge thereof and a spring plate horizontally extending from the upper edge of the pillow part and pressing the upper face of the rail bottom at the front end thereof, together with a synthetic resin. SOLUTION: A spring member 50 composed of a nearly cylindrical pillow part 54 and a flat spring 56 horizontally extending from the upper edge of the pillow part to one side thereof is integrally formed with a synthetic resin like nylon 66. And a gauge block 52 is also made of a synthetic resin like nylon 66. And hence, even if a lateral load acts on a rail 10 to push out the gauge block outside, the gauge block 52 and the pillow part 54 are prevented from being deformed. And even when the rail 10 is laterally shifted and the joint plate 20 is moved to contact the flat spring 56 at the worst, the electrical insulating condition between the rails at both sides of the joint can be kept since the spring member 50 itself is an insulating material.

Title: Semiconductor storage device
Inventor: GOTO KENJI
IPC: G11C11/41
Filed: 1993-11-02
Abstract: PURPOSE:To attain the high speed of a memory cell readout speed by connecting gate potentials of bit line level compensating P channel type transistors connected with a bit line to the bit line in parallel with a precharging transistor(Tr). CONSTITUTION:The data of a memory cell 2 is transmitted to bit lines D the inverse of D via switching transistors TrN1 TrN2 by selecting a word line WL with an address signal inputted from an outside. Since potentials of bit lines are previously precharged to the power source potential VCC with an inverted precharge signal the inverse of P before the word line WL is raised, the one potential of bit lines desends from the potential VCC. At this time, bit line level compensating transistors P4, P5 for a gate threshold value VT do not conduct until potentials of bit lines D the inverse of, D become lower than VCC-¦VT¦. Since potentials of bit lines falls down at high speed when transistors P4, P5 do not conduct and an input-output data control circuit 3 can operate quickly, the readout speed of the cell 2 is made high speed.

Title: Semiconductor device
Inventor: NAKAHIRA YOSHIKUNI
IPC: H01L25/07
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To prevent failures such as cracks in a main case during fixation of a power module such as IGBT (semiconductor power device). SOLUTION: A main case 11 and a ring-shaped metal fitting 13 are molded in one piece by insert molding. The upper end of a lower ring-shaped part 13a of the ring-shaped metal fitting 13 protrudes a little from the back of a screw hole 11b so that it may be in contact with a radiating plate 16. This prevents the stress caused by the tightening torque of the bolt from acting upon the main case 11 through the ring-shaped metal fitting 13 when the main case 11 is fixed to a radiator fin and makes the ring-shaped metal fitting 13 hardly be detached from the main case.

Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a multiplexer having an internal cache memory with which a system managing mode memory mixed with a regular system memory can be cached. SOLUTION: An address translator 115 passes an address without changing it in regular mode and translates the address to an address range out of range of address to be occupied by an external storage device in system managing mode. A cache memory 160 is connected to the address translater 115 and caches data according to an address tag corresponding to the address received from there. The address translator 115 is provided with an address range comparator and can be combined with address translation from virtual memory to physical memory. An inverse address translator 120 is provided with an inverse address comparator and when a cache line write-back address is settled within the translated address range, a coincidence signal is generated to an external system.
