Title: Thruster system for control of spacecraft attitude and speed
Inventor: SACKHEIM ROBERT L
IPC: B64G1/26
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a rocket propulsion system for spacecraft for attaining a very economical, reliable and efficient rocket. SOLUTION: Monopropellant RCS thrusters 1a to 1f are employed for attitude control, and bipropellant SCAT thrusters 5a to 5c are used for speed control. Both sets of thrusters 1a to 1f and 5a to 5c are designed to use the same liquid fuel. The fuel is supplied from a pressure-uncontrolled pressure tank for blowdown mode operation. Such propulsion systems as thrusters for position holding and attitude control work in conjunction with high-propulsion apogee kick engines also having a SCAT thruster structure employing the same fuel. The fuel and oxidizer are preferably hydrazine and dinitrogen tetroxide. This system is easily convertible from an existent monopropellant system to a high- quality bipropellant dual-mode system, without complication and cost increases resulting from the use of dinitrogen tetroxide-hydrazine-based bipropellant devices.

Title: Monitoring device
Inventor: SUDA KAORU
IPC: G08B13/18
Filed: 1987-12-28
Abstract: PURPOSE:To freely use plural operating devices by eliminating regulation on wiring between the operating device and a controller by forming a prescribed monitoring device by connecting plural operating devices and controllers by a bus shape control signal transmission path. CONSTITUTION:When a power source is applied, the operating devices 21 and 22 monitor the state of a control signal line 24 at a comparison part 35 via a reception part 34, and start to transmit a control signal only when no reception data exists. On the other hand, when the data exists on the control signal line 24, a reception state is set by terminating the issuing of output from a transmission part 33 by a transmission control part 36. While the control signal is transmitted from the transmission part 33, transmission data is compared with the reception data at the comparison part 35, then, the coincidence of the reception data is confirmed. When discrepancy is detected, the transmission is terminated. Meanwhile, in the reception state, the presence/absence of the reception state is decided at the comparison part 35, and when a state where no reception data is received continues for a prescribed period or more, a mode is set at a transmission mode. A conversion part 32 analyzes the reception data, and displays an operating state on a display part 37.

Title: Class b output amplifier circuit
Inventor: KUBO KUICHI
IPC: H03F3/30
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To operate an amplifier circuit with low voltage, to set a distortion characteristic to be satisfactory, to improve operation efficiency and to reduce the fluctuation of an output level owing to the change of a load resistance by inserting a capacitor between the base of a first transistor and the base of a second transistor. SOLUTION: A complementary class B output circuit is formed by the first and second transistors Q1 and Q2. The capacitor C is inserted between the bases of the first and second transistors Q1 and Q2. Input signals given to the bases of third and fourth transistors Q3 and Q4 drive the first and second transistors Q1 and Q2 in output stages. When a since wave signal is inputted, the positive peak value of the transistor Q1 is pushed up by the charging charge of the capacitor C and the negative peak value of the transistor Q2 is pushed down by the charging charge of the capacitor C. Thus, the output signal of an output terminal Out has not distortion.

IPC: G03F7/09
Filed: 1990-11-29
Abstract: PURPOSE:To improve resistance to printing ink and cleaning oil and to enable storage over a long period of time by forming a barrier layer on a substrate with an adhesive layer. CONSTITUTION:A photoset barrier layer of 3-100mum thickness is interposed between a substrate with an adhesive layer and a photosensitive resin layer. The barrier layer is a highly cross-linked resin layer and prevents printing ink and ink cleaning oil from infiltrating into the adhesive layer, swelling the layer and causing the falling of a relief from the substrate. The photosensitive resin layer laminated on the barrier layer is very tightly adhered to the unphotoset part of the surface of the barrier layer by imagewise exposure and post-exposure in the conventional photomechanical process. The resulting relief is tightly held by the substrate and the falling of the relief is prevented. A photosensitive resin relief printing material ensuring very satisfactory relief retentivity and having high resistance to printing ink and cleaning oil is obtd.

IPC: G03G15/20
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To prevent not only the offset of an image caused by the offset of toner to a fixing roller but also the adhesion of the toner to a pressuring roller caused by the adhesion of calcium carbonate incorporated in recording material to the fixing roller and the back soiling of the recording material by the toner from the pressure roller in the case of fixing a toner image while the recording material on which the toner image is carried is consecutively made to pass. SOLUTION: A diode 9 is connected between the pressure roller 2 and ground in a state where its anode is set on the ground side. When a prefixing recording material detection sensor 16 detects that the recording material 6 exists in a fixing nip N, DC-700 V fixing bias having the same polarity as the toner is impressed on the fixing roller 1 in order to prevent the offset of the toner to the roller 1 from the toner image 7 on the material 6. When a postfixing recording material detection sensor 17 detects that the material 6 does not exist in the fixing nip N, the impressing of the fixing bias is stopped in order to transfer the positively electrified calcium carbonate adhering to the roller 1 from the material 6 at the time of fixing to the roller 2.

Abstract: PURPOSE:To remove creeping of a resist liquid onto the rear of a wafer, and to prevent the fouling of the rear at the time of the application of the resist onto the wafer by installing a duct around a wafer holder in a spinner. CONSTITUTION:A duct 5 is mounted around a wafer holder 1, and blows off air as required. When a wafer 3 is fixed to the wafer holder 1 and air is blown off from the duct 5, pressure spraying air from the duct 5 is brought to strength in an extent that fixing to the wafer holder 1 of the wafer 3 is not prevented. A resist liquid is dropped onto the wafer 3, and the wafer holder is turned at high speed. The excess resist liquid on the wafer is scattered by centrifugal force at that time, but it does not creep on the rear of the wafer 3 by air sprayed from the duct 5 and is scattered. Accordingly, the fouling of the rear of the wafer is effectively prevented.
