Title: Method and system for plasma processing
Inventor: YOKOGAWA KATANOBU
IPC: H01L21/3065
Filed: 1999-11-01
Abstract: PROBLEM TO BE SOLVED: To obtain a plasma processing system in which the processing performance can be controlled with high accuracy by controlling the active species in plasma independently from generating conditions of plasma, i.e., the pressure, flow rate and composition of material gas, and the characteristics can be sustained stably for a long term. SOLUTION: Plasma is formed through interaction of an electromagnetic wave of 300-500 MHz and a magnetic field and an electromagnetic wave of 50 kHz-30 MHz is superposed on the electromagnetic wave of 300-500 MHz on a flat plane 5 for introducing electromagnetic wave. Interval between the flat plane 5 and a sample 6 to be processed is set equal to or less than one half of the diameter of the sample 6 and active species is controlled depending on the interval. Consequently, active species in the plasma can be controlled effectively and independently from the generating conditions of plasma and the processing performance can be stabilized for a long term.

Title: Linear pulse motor driving circuit for floppy disk device
Inventor: KIMURA HITOSHI
IPC: G11B21/08
Filed: 1990-11-16
Abstract: PURPOSE:To prevent generation of seeking errors even when a seeking action is performed at a high speed by providing a first stage circuit that converts and outputs the intervals of inputted pulse strings, a second stage circuit that outputs braking signals, and a decoder that determines an energizing pattern depending on the state of these outputs. CONSTITUTION:A stepping pulse signal 1 sent from a host is converted to pulse strings having a prescribed intervals by the first stage circuit 3. By allowing this conversion to have a constant speed after the rotational speed of the linear pulse motor 11 is gradually raised, the generation of seeking errors is prevented. Also, when the intervals of the pulse strings in the stepping pulse signal 1 exceed a prescribed period, that is, when a constant time is elapsed after the last pulse is sent, the linear pulse motor 11 is retreated by one pulse for a fixed time when the braking signals are outputted, and then returned to the original position. Thus, even when the stepping pulse signals having short fixed intervals are sent from the host, no seeking errors are generated.

Title: Gas fuel engine
Inventor: IMADA MICHIHIRO
IPC: F02D45/00
Filed: 1994-12-15
Abstract: PURPOSE: To improve torque shock by comparing a control start timing of fuel supply amount in direct injection condition with fuel supply amount control start timing in pre-mixed injection condition when fuel supply condition is switched over and setting a specified delay time. CONSTITUTION: Those data such as engine speed, accelerator opening, intake air amount is read and, based on the accelerator opening data, a basic accelerator opening for pre-mixed injection → direct injection or direct injection → pre-mixed injection is calculated. In a steady-state in which fuel supply is not in the pre-mixed injection →direct injection nor direct injection →pre-mixed injection condition, when the present accelerator opening is judged to be higher than a reference accelerator opening which requires the switching of fuel supply condition to the pre-mixed injection direct injection condition with higher torque requirement, the set timer value of a fuel ratio increasing and decreasing delay timer under pre-mixed injection condition is set to Tp1 in order to gradually reduce the change of fuel ratio Rp.  Then the set timer value of the fuel ratio increasing and decreasing delay timer is set to Td1 so as to change the fuel ratio Rd in the direct injection condition, and a specified delay time is set in comparison it with a fuel control start timing in the pre-mixed injection condition.

Title: Interference measuring method and device thereof
Inventor: NOZAWA RYUSUKE
IPC: G01B11/24
Filed: 1990-11-16
Abstract: PURPOSE:To enable high-accuracy measurement of interference fringes by detecting the variation of the relative distance between a reference surface and a surface to be examined from the change of interference fringes of a reflected light, and by finely moving the reference surface or the surface to be examined so as to offset the above variation. CONSTITUTION:When the relative distance between a reference surface 3 and a surface 4 to be examined varies due to the excitation of external vibration or the like, an interference fringe detecting means 5 of an interferometer 2 detects it as the change of interference fringes. Since the change of the interference fringes is the two-dimensional movement of interference fringes, at a specific measuring point, it appears as a change in brightness. The detecting means 5 detects the change in brightness at a plurality of measuring points, and converts it into an electric signal for outputting it to a signal processing means 6. On the basis of this electric signal, the processing means 6 calculates the variation of the relative distance between the reference surface 3 and the surface 4 to be examined, and also calculates a correction value for offsetting this variation, and controls a driving means 7 so that the reference surface 3 performs a fine movement corresponding to the correction value.

Title: Cofocus scanning type microscope
Inventor: IWASAKI OSAMU
IPC: G02B26/10
Filed: 1989-12-01
Abstract: PURPOSE:To assure a large main scanning width as a whole even if the respective main scanning widths of light spots are small and to allow high-speed scanning by simultaneously irradiating and scanning a sample with the plural light spots of illuminating light and discretely detecting the generated plural spot images. CONSTITUTION:An LD array 5 is integrally held on a moving base 15 and n-pieces of light emitting parts are so driven as to simultaneously emit laser beams 11. The light spots P of n-beams (only the two beams are shown in fig.) of the illuminating light 11 are formed by a transmission optical system 18 on the sample 23 imposed on a sample base 22. The respective transmitted beams 11' transmitted through the sample 23 are imaged at a spot image Q by a light receiving optical system 21. These spot images are discretely detected by a photodetector 9. The assurance of the arraying pitch of the light spots is eventually merely necessitated for the actual main scanning widths of the respective light spots even in the case of obtaining of the large main scanning width if the microscope is constituted in such a manner. The utilization of a piezoelement, etc., which allow high-speed oscillation is, therefore, possible even if the large moving stroke cannot be taken. The high-speed scanning is thus attained.

Abstract: PROBLEM TO BE SOLVED: To efficiently perform a double-sided copy by arranging a longitudinally freely movable fence against which transfer paper discharged to a tray after a signal-sided copy is butted, and controlling so as not to perform press by a pressing member when the fence exists in a sending-out position in a reversing paper feeder of a copying machine to perform a double-sided copy. SOLUTION: When a double-sided copy is performed, first of all, a control part moves a back fence 9 to a standby position by driving a step motor 11, and then, lowers a pressing plate 7. When the last 2N pages of an even number of documents are discharged to an intermediate tray 6 after a single-sided copy is performed in this condition, the back fence 9 is moved to a sending-out position, and transfer paper 2 is sent out to a paper refeedable position. At this time, since the pressing plate 7 is raised as the back fence 9 moves to the sending-out position from the standby position, the transfer 2 can be moved to the sending-out position without contacting with the pressing plate 7. When the transfer paper 2 is moved to the sending-out position, the back fence 9 is moved to the standby position.

Abstract: PURPOSE:To miniaturize a paper form separating carrying mechanism by arranging a small roller and a large roller on the same shaft, and providing a separating plate in contact with the small roller, an auxiliary roller in contact with the large roller, and a paper form detecting sensor. CONSTITUTION:In a separating carrying roller 1, rollers of two kind diameters consisting of a small roller 2 small in diameter and a large roller 3 large in diameter are arranged on one shaft 4 to transmit driving force. Therefore, the peripheral speed of the large roller 3 becomes faster than the peripheral speed of the small roller 2.

Therefore, mechanism is simple and can be miniaturized.
