Inventor: NAKAZATO YOSHIO
IPC: C22C38/00
Filed: 1982-04-24
Abstract: PURPOSE:To obtain a titled high tension steel plate having a mixed structure in which an island-like structure containing martensite has been dispersed in a ferrite base, by regulating a surface roughness and a proportional limit stress by specifying a mean surface roughness Ha, and a PPI value, respectively. CONSTITUTION:A high tension steel plate which has such surface characteristics as specified by 0.4-1.8mum mean surface roughness Ha and >=80 (in a 0.5mum cut- off level) PPI value, and also has <=20kg/cm<2>, especially, <=18kg/cm<2> proportional limit stress is excellent in a workability for pressing especially, a form freezing property. When manufacturing this steel plate, raw material steel is hot- rolled, and after that, when cold-rolling it to a final gauge, characteristics required for the final product are obtd. at the final rolling stage. Subsequently, a cold rolling plate having desired surface characteristics is heat-treated in order to obtain a desired structure, that is to say, a structure which generates no stretcher strain in a state as it was heat-treated. In this way, a high tension steel plate can be obtained.

IPC: B60J7/00
Filed: 1985-03-29
Abstract: PURPOSE:To improve a ventilating effect at the time of tilting motion of a glass panel, by opening a sun shade in a way of interlocking the tilting motion of the glass panel. CONSTITUTION:A sun shade 9 is installed in a lower part of a glass panel 3 operated into tilting motion by a lifting gear 5 free of longitudinal movements along a glass rail 6. First, when a wire holder 12 of this lifting gear 5 is moved forward, a driving pin 15 is engaged with a cam groove 14 whereby a lifting cam is uplifted. Then, a connecting pin 18 lifts a cam 17, and the glass panel 3 is tilted up. When tilting motion of the glass panel 3 is started, a sun shade 9 is opened in response to the tilting motion by operation of an interlocking mechanism (unillustrated herein). Thus, when the glass panel 3 is tilted up, the sun shade is autmatically opened so that the ventilating capacity required is securable without installing a ventilating louver.

IPC: H04L29/02
Filed: 1990-03-19
Abstract: PURPOSE:To improve the utilizing efficiency of a CPU by stopping the reception processing and data transfer of DMA till a text start detection section detects a succeeding text start character when the CPU receives an interruption request of error. CONSTITUTION:When an error detection section 12 detects an error, a reception section 1 applies error processing interruption request to a CPU 3. Upon the receipt of the error processing interrupt request, the CPU 3 resets a text start detection section 2 to an H level immediately to bring the mode to a test start character detection standby state. While the text start detection section 2 is kept to an H level, the state such as error detection stop of the reception section 1, countup of an address in a DMA control section 4, stop of count-down of a byte counter, and write inhibit to the memory from the DMA control section 4 is reached. Thus, the useless processing of the CPU 3 is eliminated and the utilizing efficiency of the CPU 3 is attained.

Abstract: PURPOSE:To reduce the chip size by devising the titled circuit such that a 2nd MOS transistor(TR) is not electrified when a 1st MOS TR is electrified and a logic circuit is electrified and the 2nd MOS TR is electrified when the 1st MOS TR is electrified and the logic circuit is not electrified. CONSTITUTION:A MOS TR 7 is electrified at a half period of a clock signal PHIand an output terminal OUT 1 goes to a high level. When any of control signals E1-E3 at a high level or all of them are at a low level at the remaining half period of the clock signal PHI, for example, when the control signal E1 is at a high level, the logic circuit 2 is electrified the output OUT1 goes to a low level because of the conduction of the MOS TR 1 and the MOS TR 7 is not electrified. When the control signals E1-E3 are all at a low level, all the logic circuits 2,4,6 are not electrified. Thus, the output terminal OUT1 goes to a high level although the MOS TRs 1,3,5 are electrified and the logic circuit 8 electrify the MOS TR 7.
