Title: Binarization method for halftone image and storage medium
Inventor: YOSHIDA YASUNARI
IPC: G06T5/00
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To prevent a low density part from being affected by the diffused and stored minus errors when a halftone image is binarized. SOLUTION: When a marked pixel is not turned on (S310, NO), the cumulative error value ES is calculated based on the binarization error value ERR (S315). It is decided whether the sum of the value ES and the binarization error value of the marked pixel is smaller than the prescribed decision value ESM (S330). If the sum is smaller than the value ESM, the absolute value is reduced by multiplying the value E by a coefficient (k) and distributed to the error buffers (e) of peripheral pixels based on an error distribution matrix Bmat () (S340). Then the value E of the marked pixel is stored in a work memory as the binarization error value ERR (s) of the s-th pixel (S360). Then the next pixel processing is ready.

Title: Variable delivery type vane pump
Inventor: ABE AKIHARU
IPC: F04C14/22
Filed: 1991-12-17
Abstract: PURPOSE:To lubricate a cam ring reliably without deteriorating a volumetric efficiency. CONSTITUTION:In a place where a pressure difference between the inner peripheral side and the outer peripheral side of a cam ring 22 is small, width measured in the radial direction of the side surface coming into a sliding contact with the inner surface of a pump body 1 of the cam ring 22 swinging with a pivot pin 3 as its center is set narrower than in a place where the pressure difference is large.

Title: Control method for wire electric discharge machining
Inventor: FUKUZAKI YUJI
IPC: B23H7/06
Filed: 1999-12-13
Abstract: PROBLEM TO BE SOLVED: To provide a method of electric discharge machining capable of suppressing a shape sagging and an unmachined amount in a discharge machining by determining the machining conditions for a machining route with variable speed vector allowing a wire electrode to be passed through by the function using the arc radius of the machining route as a variable. SOLUTION: When a wire electrode reaches an approach area 61b before a crossing point 51 in a linear machining distance 61, a machining speed V2 at the crossing point 51 having a crossing angle α1 where two linear machining distances 61 and 62 are connected to each other is set slower than a machining speed V1 in the linear machining distance 61 according to the connection status of the crossing point 51. Because the approach area 61b and crossing point 51 are machined at the machining speed V2 the shape sagging in electric discharge machining can be suppressed by the delay of response to a movement along the machining locus of the wire electrode.

Title: Liquid ejecting container
Inventor: KOHARA HIROTSUGU
IPC: B65D83/42
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To prevent liquid from dripping and leaking out when a container falls clown with a simple structure by providing a circular piston having its lower face locked with an upper face of a locking part at the lower end of an extraction cylinder by applying force downward with a coil spring and a valve member comprising a head with an ejection hole fitted to the upper end of a push-to-open-type valve. SOLUTION: When a liquid ejecting container 1 is used, first a peripheral wall 21 of a cap-like member 4 is screwed up, whereby the inside of a cylinder 12 is reduced in pressure to have liquid in a container body 2 sucked up, the liquid passes through a pipe 16, and it is sucked into the cylinder 12 with a suction valve 15 opened. At this time, a locking part 24 pushes up a piston 6 while rotating. Then the peripheral wall 21 is screwed down to have the cap-like member 4 restored. If a head 42 is pushed down from this state, a valve 40 opens, and since the liquid in the cylinder 12 is in an increased pressure by force applied downward by a spring 35, the liquid in the cylinder 12 is ejected through an extraction cylinder 23 from an ejection hole 41 of the head 42 via the valve 40.

Title: Forming method for rear face board of plasma display panel
Inventor: MATSUZAWA HIROSHI
IPC: H01J11/38
Filed: 1999-12-14
Abstract: PROBLEM TO BE SOLVED: To provide a forming method for a rear face board of a plasma display panel having a partition with a uniform height and a dielectric layer with a uniform film thickness. SOLUTION: In the method of forming a partition geometry by reverse duplicating a forming die for a rear face board of a plasma display panel having a stripe channel geometry on a surface as a female die of the partition, the thin film dielectric layer can be obtained after burning, even though the film of the dielectric layer before burning has been thick, by increasing a resin content of an inorganic material paste which forms the partition and the dielectric layer, and by enlarging the shrinking percentage during burning. In this method, it is possible to easily form the dielectric layer with a uniform film thickness. In addition, the same effect is obtained by using a glass frit with a low melting point as an inorganic material for the partition and the dielectric material, or by reducing the aggregate content in the inorganic materials.

Title: Vacuum container
Inventor: OTANI TOSHIHIRO
IPC: H05H13/04
Filed: 1998-12-14
Abstract: PROBLEM TO BE SOLVED: To reduce influence of eddy current by providing a plurality of non-conductor reinforcing ribs axially mounted on the outside face of a vacuum container main body at predetermined intervals over the whole cross sectional circumference of the vacuum container main body made of a metallic tube. SOLUTION: Over the whole cross sectional circumference of a vacuum container main body 2, a plurality of plate type ceramic non-conductor reinforcing ribs 31 are brazed/welded axially at predetermined intervals so as to be connected to the outside face of the vacuum container main body 2. The inside of the vacuum container main body 2 will become deformed because of applied external pressure when it is evacuated into a vacuum, however, the deformation is suppressed by the non-conductor reinforcing ribs 31. The non-conductor reinforcing ribs 31 are not conductors, so that no eddy current is generated by an alternating magnetic filed generated in a magnetic pole of an electromagnet. Therefore, limitation of the number of installed rib plates does not have to be taken into consideration, and sufficient reinforcement can be carried out.  On the other hand, the plate type reinforcing ribs are installed at optional intervals, so that the container can be manufactured at low costs.

Abstract: PROBLEM TO BE SOLVED: To efficiently scavenge minor constituent in gas by a simple device by spraying sample gas and pure water in fog to scavenge minor constituent in the sample gas in the pure water. SOLUTION: When a recovery chamber is decompressed by a pump 18, air in a mist chamber 9 is sucked through a tube 13 in the recovery chamber 14 and the interior of the chamber 9 becomes negative in pressure so that sample gas is jetted into the chamber 9 through a filter 2 and a gas nozzle 5. Further, pure water in a bottle 8 is also sucked into a water nozzle 6 through a tube 7. Water is jetted into the chamber 9 through the water nozzle 6 by the negative pressure in the chamber 9 and Venturi negative pressure produced by gas jetted from the gas nozzle 5, so that water is diffused like a mist, water soluble constituent in gas is dissolved in gas, and fine grains are scavenged in the mist. The mist and vapor are passed with a flow to the recovery chamber 14 from the chamber 9 through the tube 13, and bubbled in a bottle 15, whereby water in the bottle 15 is sampled and analyzed.
