Title: Plasma etching apparatus
Inventor: KAMIIDE KOYO
IPC: H01L21/302
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a plasma etching apparatus which suppresses an electron- shading phenomenon and which can execute a precise micromachining. SOLUTION: In an etching apparatus, a cylindrical electron-capturing electrode 26 which is extended upward so as to surround a substrate W on a substrate susceptor 18 is installed around the substrate susceptor. The electron- capturing electrode 26 is situated at the lower part of a plasma generation region P, and it is installed in such a way that it is separated slightly from the substrate and that it is electrically in a noncontact state with reference to the substrate susceptor 18 and the substrate W. In addition, a variable-voltage constant-voltage DC power supply 28 is connected to the electron-capturing electrode 26, and a + bias at a potential which is optimum for suppressing an electron-shading phenomenon according to a process condition can be applied to the electron-capturing electrode 26.  Electrons and ions which are incident on the substrate W are controlled so as to be balanced by the electron-capturing electrode 26. Thereby, it is possible to realize a pattern working operation in which the electron-shading phenomenon is suppressed and in which an abnormal shape and electric damage due to the accumulation of the electrons and the ions are not generated.

Title: Ink jet recording medium
Inventor: RIYUU HA
IPC: D21H19/38
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To form an ink receptive layer of a laminar structure consisting of at least, one layer with a top layer containing colloidal silica having high luster and high density as one peak of the pore distribution curve of the top layer represents the specific value of a pore diameter. SOLUTION: This ink jet recording medium consists of an ink receptive layer provided on a sheet-like support such as film. The ink receptor of this medium is of the laminar structure having at least, one layer, and at least, the top layer of this structure contains colloidal silica. In addition, at least, one peak of the pore distribution curve of the top layer of the ink receptive layer is set to 2-100nm. If the position of the peak of the pore distribution curve is equivalent to a less value than this 2-100nm range, the ink absorptive rate is low. On the other hand, if the position of the peak of the pore distribution curve is equivalent to a higher value than 100nm, the ink is apt to easily spread and therefore, a delicate dot cannot be obtained. Further, the surface of the ink jet recording medium appears to be coarse and might lose a smoothness.  Besides, if an adhesive is added to the top layer, the colloidal silica hardly becomes condensed in a dispersing liquid, so that the colloidal silica needs to be dispersed in the state of a primary particle.

Title: Magnetic tape device
Inventor: YANAGIBASHI YOSHINOBU
IPC: G11B15/467
Filed: 1993-12-17
Abstract: PURPOSE:To accurately control tape speed by extracting a synchronizing pulse in a synchronizing pulse area included in a prescribed format together with a data area and controlling the tape speed based thereon. CONSTITUTION:The track format is recorded on a tape 5 beforehand by a recorder with high precision. ID fields of every sectors have a synchronizing signal area, address mark area, ID data area and CRC area. A synchronizing pulse extraction circuit 27 extracts only the synchronizing pulse in the synchronizing area in response to a synchronizing pulse extraction gate pulse generated from a timing signal forming circuit 28 synchronizing with the synchronizing signal area. Thus, the operation bringing the phase of the synchronizing pulse close to the phase of a reference pulse is caused, and the speed of the tape 5 comes close to a prescribed speed corresponding to the reference pulse.

Title: Testing circuit of serial transmission function
Inventor: SUGIO TORU
IPC: G01R29/08
Filed: 1989-12-28
Abstract: PURPOSE:To enable checking regardless of the communication mode of an object to be checked by providing means for comparing a counting value corresponding to a changing point of serial data with a preset value. CONSTITUTION:The checking data from a serial control unit (SCU) 6 is synchronized with a transfer clock 13 from a transfer clock oscillator (OSC) 4 and input as a transfer data 12 to a changing point detecting circuit 3. The changing point detecting circuit 3 sends a counting clock 14 corresponding to a changing point of the level of the transfer data 12 to a counter unit 2. The counter 2 counts the number of effective edges of the counting clocks 14, and sends the same to a checking circuit controlling part 1 through a TCU controlling bus 15. A transmission controlling part 5 outputs a checking data transmission completion signal 11. The circuit controlling part 1 recognizes the completion signal 11 and confirms that the read counting value from the counter 2 is a preliminarily-set value corresponding to the checking data. In this manner, the serial transmission function is checked.

Title: Fault detection system, transmission line reconstitution system and communication system
Inventor: MARUYAMA HISAYUKI
IPC: G06F11/00
Filed: 1989-12-30
Abstract: PURPOSE:To make a high speed detection to a fault with high possibility in the normal operating state by executing sequentially a fault detection means in the order of seeking a cause to a fault at a higher speed till the cause to the fault is detected. CONSTITUTION:When transmission lines 21, 22 are normal, a data is sent through any of them and a monitor signal is sent to the other transmission line as a standby transmission line and when the transmission lines are in loopback state, the data is sent through both the transmission lines. That is, signal detectors(DET) 27, 31 receive a special control signal of 'invitation' or a special control signal 'monopoly' or a monitor signal from the data frame during data transmission. Since it is in the case of occurrence of a fault in a transmission line receiving a monitor station(ST) or an ST located at an upperstream to the transmission line when no signal is received, that is, in the state of no signal, and when DETs 27, 31 of the ST detects a no signal state, the ST enters the transmission line reconstitution operation. Thus, high speed detection is attained.

Title: Fluid sensor diagnostic device
Inventor: YAMADA TETSUYA
IPC: G01F1/00
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To detect whether a fluid sensor is out of order or not during the detection of a flow rate and flow speed of the fluid by controlling a valve opening sensor so as to output a detection value of the specified cycle, which alternately shows values larger and smaller than the detection value of a fluid sensor at the time of normal operation of the fluid sensor. SOLUTION: In the case of the structure that detection value of a valve opening sensor 5 is changed on the basis of the driving signal, a control means 10a supplies the driving signal of the specified cycle to the valve opening sensor 5 and controls the valve open degree sensor 5 so as to output the detection value of the specified cycle, which alternately shows values larger and smaller than the detection value of a fluid sensor 3 at the normal operation time of the fluid sensor 3. With a processing by the control means 10a, in the case where the fluid sensor 3 is normally operated, a comparing means 11 generates the signal at the same cycle as the cycle of the driving signal to be supplied by the control means 10a, and a detecting means 12 detects this signal so as to detect that the fluid sensor 3 is normally operated.  In the case where detection value of the fluid sensor 3 is charged on the basis of the driving signal, the control means 10b supplies the signal.
