Title: Titanium sputtering target
Inventor: HANAWA KOICHI
IPC: C23C14/34
Filed: 1992-01-30
Abstract: PURPOSE:To accelerate the forming rate of a titanium film by constituting a target for sputtering of titanium having a specified working aggregate structure. CONSTITUTION:At the time of forming a titanium film by sputtering with a titanium target material, the target for sputtering is constituted of titanium whose working aggregate structure or recrystallization aggregate structure is expressed by (0002)+ or -alpha(alpha=0 to 90). The azimuth of the target is regulated by controlling the conditions of the rolling temp., rolling direction, draft or the like. Thus, the film forming rate can be accelerated and its productivity can be improved compared to the case in which the conventional target material is used.

Title: Video printer
Inventor: SUGIYAMA TADASHI
IPC: H04N5/76
Filed: 1993-02-26
Abstract: PURPOSE:To facilitate the operation by controlling a VTR from a video printer outputting a reproduced signal from the VTR to a monitor and printing out a desired pattern. CONSTITUTION:While a tape is reproduced by a VTR 20, when a system controller 190 detects the depression of a freeze button 90 or a pattern designation button 94, the controller sends a control signal to start rewinding of the VTR 20 and starting again reproduction from a control terminal CTR. When the reproduction position of the tape comes around a button depression detection position, a video signal of the pattern is received in a memory 110 and a stop signal is sent to the VTR 20. Thus, a desired pattern is fetched in the memory 110 with only button operation of a printer 10. In this case, even when the depression of the buttons 90, 92 is delayed, so long as a succeeding pattern is not selected, the controller allows the VTR 20 to rewind a tape automatically and signal fetch on a desired pattern is executed accurately.

IPC: B60L7/12
Filed: 1987-02-24
Abstract: PURPOSE:To prevent the overvoltage of a filter capacitor from being generated, by controlling the continuity of a field chopper to be a maximum value when regenerative braking control is turned OFF, and by reducing the field current of a DC series motor quickly. CONSTITUTION:While regenerative braking command signal is exsistent, a switch 18 is connected to a feedback control side for controlling the continuity of a field chopper 11 to coincide with a field system rate pattern R0 found by the ratio of motor current IM and field current IF. In the meantime, when the regenerative braking command signal is interrupted, then by one-shot pulse from a one-shot multivibrator 17, a switch 1 is connected to one side for controlling the continuity of the field chopper 11 to be a maximum value. Then, the field current is suddenly reduced with a time constant determined by the constant of a field winding 10F and the field chopper 11. As this result, the output voltage of a DC series motor 10 is also lowered along with the reduction of the field current, and the voltage of a filter capacitor 5 is not turned into overvoltage.

Filed: 1986-02-26
Abstract: PURPOSE:To reduce a coupling noise by alternately wiring a signal line for forming a bus line, and a signal line of a test bus not used at normal operation time like a signal line for testing a logic circuit in a semiconductor chip. CONSTITUTION:Signal lines BL0-BL15 for forming a data bus DB and signal lines TB0-TB15 for forming a test bus TB are alternately wired. The bus DB transfers data by a dynamic operation. When desired data must be multiplied, desired data is input to a multiplier 2 from the bus DB, and the product of data is output. The buses TB0-TB15 which are not used at normal operation time are wired among the lines BL0-BL15 for forming the bus DB, and coupling capacity among the signal lines for forming the bus DB can be ignored. Thus, after precharging, when either signal line is discharged, the influence of the coupling noise to the adjacent signal line of high level is reduced.
