Title: Resonant inverter and electric rolling stock using the same
Inventor: MASAKI RYOZO
IPC: B60L9/18
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To reduce losses in a switching element and electromagnetic noise during the drive of a motor by using silicon carbide for a semiconductor switching element of a resonant inverter of a reactor and a capacitor, and specifying the maximum rated voltage. SOLUTION: The energy of a battery 2 is converted into three-phase AC by a resonant inverter 4 and is supplied to an AC motor 1. The resonant inverter 4 is constituted of a three-phase bridge circuit for flowing current in the respective three phases, a resonant reactor 6 constituting a resonant circuit, and a resonant capacitor 7. In the semiconductor switching element of the three-phase bridge circuit, SiC power elements Sup, Sun, Svp, Svn, Swp, and Swn are used, which are formed of silicon carbide having a withstand voltage of 700 V or higher to 1,100 V or lower. These six SiC power elements are respectively on/off controlled by drive signals Pup, Pun, Pvp, Pvn, Pwp, and Pwn outputted from a controller 5. Voltage applied across it at the time of switching the SiC power elements becomes zero, thus hardly any loss occurs.

Title: Exposure of semiconductor device
Inventor: ICHIKAWA SEIJI
IPC: H01L21/30
Filed: 1989-12-29
Abstract: PURPOSE:To enable various kinds of patterns to be exposed by a method wherein multiple marks, including alignment mark and shot data marks, are made in one shot region on a semiconductor wafer while the alignment marks are detected during the contracted exposure process and then the shot requirements are selected by the shot data. CONSTITUTION:Alignment marks 7 and shot data marks 6 are made in respective shot regions by contact exposure process. Simultaneously with the detection of the marks 7, the other marks 6 are read-out to select the shot requirements as well as the exposure level is corrected by a controller 8 for effecting the step align exposure. The photoresist film is thicker in the outer peripheral part than in the central part, however, this film can be exposed in high yield since the thickness can be corrected by correction exposure data (a). Furthermore, the shot requirements can be selectively changed thereby enabling various contracted patterns to be exposed meeting different requirements by selecting specific reticle so that small quantity production of various kinds may be carried out efficiently in high yield.

Title: Method and equipment for manufacturing superconducting joint
Inventor: KOSKY PHILIP GEORGE
IPC: C23C16/46
Filed: 1992-12-01
Abstract: PURPOSE: To form a superconducting joint used for connecting the ends of continuous superconductors together on a superconducting tape by removing all the non-superconductive material from one end of the tape and depositing a superconducting connection alloy at the end through the CVD reaction. CONSTITUTION: After the removal of all the non-superconducting material from one end of a superconducting tape 15, a conductive joint is physically connected to the tape end, on which a superconductive alloy layer is deposited for fixing the joint. The deposition is based on the CVD reaction between hydrogen and halide in the main metal and the reactive metal. That CVD reaction occurs in a temperature range from 700 to 950 deg.C. This means the heating of the exposed portion of the tape end in that temperature range triggers chemical vapor deposition at the exposed portion of the alloy layer. When the layer of an appropriate thickness is formed, the flow of the reactive gas is checked, and the device is recharged with inert gas and then cooled down. Then, bolts 4 are removed, a housing 1 and a board 2 are separated to remove the connected tape 15.

Abstract: PURPOSE:To reduce the capacity of information to be transmitted and to shorten the communication time of a management information report by dividing the management information into sending slip information and format specifying information to transmit the information from the transmitter side and allowing the receiver side to combine the developed sending slip dot information and format specifying dot information and print out the information. CONSTITUTION:A transmitting user sets up an original on the transmitter and inputs a sending slip such as a destination name from an input part 1 by key operation. The input part 1 stores sending slip data coded correspondingly to each inputted sending slip in a sending slip data storing part 3. When the transmitting user depresses a communication switch, the receiver is called and transmission is started. After terminating the call to the receiver, an information receiving part 5 receives the sending slip data. Then a format specification receiving part 6 receives the format specifying information and a dot developing part 7 develops the sending slip data received by the receiving part 5 to dots. A composing part 9 reads out the dot information of the format information specified by the format specifying information received by the receiving part 6 out of the format information previously stored in a storage part 8 and combines the read dot information with the sending slip dot information developed by the dot developing part 7.
