Title: Positioning control circuit
Inventor: HORI SATOSHI
IPC: G05D3/12
Filed: 1984-09-26
Abstract: PURPOSE:To performs a positioning job of a controlled system at a high speed and with high accuracy by having the bang-bang control in consideration of the speed and acceleration as well as the position of the controlled system and also carrying out the position feedback control. CONSTITUTION:When the positioning control is carried out at a certain time point, the bang-bang control is selected by a switch part 104 with output of the maximum acceleration command value. Thus a motor 10 is accelerated together with the shift of a controlled system. When the controlled system reaches a prescribed position (x), a bang-bang control part 100 delivers the negative maximum acceleration command value by a command given from a position comparator 22. Thus the motor 10 is decelerated together with the shift of the controlled system. When the speed of the controlled system is slowed down to a prescribed level together with a prescribed acceleration, the part 100 delivers the positive maximum acceleration command value by a command given from a comparator 102. As a result, the acceleration is indicated in a deceleration mode of the acceleration and the overall acceleration is reduced. Then the switch 104 is changed over when the acceleration reaches a prescribed level. Then the controlled system is positioned at a low acceleration degree.

Title: Image forming method
Inventor: NAKAMURA HIROSHI
IPC: G03D9/00
Filed: 1989-08-03
Abstract: PURPOSE:To uniformly heat-expand a photosensitive material without creating wrinkles and to surely transfer an image onto an image receiving material by permitting an application roller and a heating means to heat the photosensitive material and the image receiving material without their trailing edges being pinched.

Title: Reading and writing system for ic card
Inventor: SUZUKI HIDEO
IPC: G06K17/00
Filed: 1985-09-10
Abstract: PURPOSE:To eliminate adverse influence exerted owing to imperfection of connection between an IC card and a card terminal by providing the IC card itself with a function which outputs an oscillating wave and an input function for the oscillating wave. CONSTITUTION:When the IC card 11 is inserted into the card terminal 21, an acoustic wave transmitting part 27 transmits an ultrasonic wave signal.

Filed: 1984-09-25
Abstract: PURPOSE:To enable characters, figures or the like to be printed with high quality by using a low-capacity driving power source, by a method wherein the dot duty in a printing line is calculated for each duty detection region covering a predetermined number of dot strings in the printing line. CONSTITUTION:A CPU10 calculates the dot duty in the duty detection region on the basis of the total number of dots stored in a total dot number storage region of a ROM12 and a number of print dots stored in a print dot number storage region 19 of a RAM14, and compares the calculated dot duty with a dot duty stored in a dot duty storage region 17 of the ROM12 to discriminate whether or not the calculated dot duty is greater than the stored dot duty. When a dot duty detection region for which the calculated dot duty is greater than the dot duty stored in the region 17 is present in a printing line, the CPU10 controls printing so that the printing in the line is performed in a plurality of printing steps. Accordingly, images, particularly figures, can be printed with high quality by using a low-capacity low-cost driving power source which is used for an ordinary printing operation.

Title: Route searching device
Inventor: TAMAKI ISAO
IPC: G01C21/00
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To consider a bypass spot and a stop-by spot on the way in the searching processing of a route from a start node to a goal node. SOLUTION: A specifying means can specify the start node and the goal node and can also specify one or plural bypass nodes and stop-by nodes (F101). When the start node, the goal node and the bypass node are specified by the specifying means, an arithmetic searching means inhibits the route of returning to the node immediately before the bypass node after reaching the bypass node from being defined as a searching object route (F114) and searches the best route from the start node through the specified respective bypass nodes to the goal node. When the stop-by node is specified, the best route from the start node through the specified respective stop-by nodes to the goal node is searched while also including the route of returning to the node immediately before the stop-by node after reaching the stop-by node in the searching object route.

Title: Bushing for spinning glass fiber
Inventor: NAKA ATSUSHI
IPC: C03B37/083
Filed: 1990-07-26
Abstract: PURPOSE:To enable to rapidly recover a spinning operation in a stable diameter state of a glass fiber even on the generation of the breakage of the fiber by forming plural circular grooves having a specific depth on the outer surface of each of many circular projected nozzles. CONSTITUTION:In a glass fiber-spinning bushing having many circular projected nozzles on the bottom surface of a bushing plate of the bushing, plural circular grooves each having a depth of 0.5-50mu are formed on the outer surface of each nozzle. Since the bushing has large glass-wetting resistance on the outer surface of the nozzle, the spreading of the wetting of the melted glass toward the outer surface of the nozzle is prevented. Consequently, the glass fibers having a high quality can be prepared highly efficiently, because the breakage of the glass fibers is minimized. Since the melted glass naturally falls from the nozzle even when the glass fiber is broken, the melted glass can be readily drawn out from the nozzle and the spinning operation can be rapidly recovered in a stable diameter state of the spun glass fiber.

Title: Gas separation method employing two kinds of membranes
Inventor: KATO MORITAKA
IPC: B01D53/22
Filed: 1987-08-11
Abstract: PURPOSE:To make it easy to control the dew point in the removal of low- volatile components, by allowing a mixed gas composed of at least any of H2, CO2 and CO and a volatile hydrocarbon gas to pass through two membrane modules having different adsorption rates for specific components. CONSTITUTION:A mixed gas composed of any of H2, CO2 and CO gases and a gas of volatile hydrocarbons is allowed to pass through a first-step membrane module through which high boiling-point components in the volatile hydrocarbon gas pass faster than methane. Subsequently, H2, CO2 or CO is separated from the resulting mixed gas by allowing the gas of H2, CO2 or CO to pass faster than the volatile hydrocarbon gas components. For example, by the use of a silicon membrane for the first-step membrane module 1 and a cellulose membrane or a second-step membrane module 2, a natural gas having a CO2 concentration of 6.23vol.% is allowed to pass through the modules, thereby obtaining a pipeline gas having a CO2 concentration of 2vol.%.
