Title: Halftone recording method
Inventor: WATANABE SUSUMU
IPC: H04N1/405
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To obtain the desired image quality of a low density image area by deciding the converted gradation value of a pixel group to be converted at each distribution pattern, setting it as the converted gradation value of about the half of the pixel to be converted selected according to the pattern uniformly distributed in the pattern of the group to be converted, setting the other pixel to be converted to zero, and stabilizing the ink density by the thermal transfer. SOLUTION: Image data is divided to image areas made of a plurality of pixels which make it possible to cover without superposition without gap. Pixel group to be converted having a gradation value not exceeding a predetermined value is extracted at each image area, the gradation value representing the group to be converted is calculated as prescribed to obtain a converted gradation value. Further, it is set as the converted gradation value of the pixel to be converted of about half selected according to the pattern distributed substantially uniformly in the pattern of the group to be converted, and the other pixel to be converted is set at the converted gradation value to zero.

Title: Lightning arrestor
Inventor: HATANAKA TAKETOSHI
IPC: H01T4/12
Filed: 1994-09-20
Abstract: PURPOSE: To improve the performance of a lightning arrestor by enabling the use of an optional metal for an electrode part. CONSTITUTION: A discharge electrode 4, where a projection 5 is made at the center, is spot-welded at the section of its projection 5 to a metallic disc 3. This metallic disc 3 is soldered to an insulated cylinder 1 both whose ends are metallized, and also inert gas is charged into its inside. This way, the end faces of discharge electrodes 4 are opposed to each other from above and below, whereby discharge faces are made. Here, for the insulated cylinder 1 and the metallic disc 3, the ones having approximately the same thermal expansion coefficient are selected, but the fusion parts of the discharge electrode 4 and the metallic disc 3 are of small area, so generated thermal stress is small, therefore, the thermal expansion coefficients need not necessarily conform to each other.  Hereby, the performance can be improved, using a metallic material of high melting point for the discharge electrode 4.

Title: Angle of inclination detector for running course
Inventor: SHIRATA TERUHIRO
IPC: G01C9/06
Filed: 1987-10-06
Abstract: PURPOSE:To enable accurate computation of an angle of inclination with the prevention of variations in a motor current due to vibration characteristic peculiar to a vehicle, by making one phase of a motor driving current overlap with DC to create a condition that an electromagnetic breaking by an eddy current of a rotor is applied. CONSTITUTION:One of two stator windings 1a and 1b of a motor 1 is made to always overlap with a DC voltage from a DC power source 10 through diodes D1 and D2 and as a magnetic field by DC is cut with the rotation of a rotor 1c, an eddy current within the rotor 1c is generated so that a magnetic field by the eddy current produces a braking action with respect to a rotary magnetic field with windings 1a and 1b. This enables detection of a stable motor load current with a reduction in a vibration component given by an external force from both ends of a resistance R thereby assuring accurate computation of a gradient of a road surface.

Title: Analytical sample preparing device
Inventor: NAKANO TOMOHIRO
IPC: G01N1/10
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To reliably replace filter paper without using a filter holder. SOLUTION: An sucking nozzle 403 is lowered from above into a filter paper magazine case 402 to house filter paper 401, and the filter paper 401 is sucked by negative pressure. When the sucking nozzle 403 is raised, an edge peripheral end part of the filter paper contacts with a projection 406, and the filter paper deflects upward. At this time, a clearance is generated between filter paper directly brought into close contact with the sucking nozzle 403 and filter paper under it among sucked plural filter paper, and sucking force weakens, and the filter paper falls. Therefore, only single filter paper is taken out of the filter paper magazine case 402.

Title: Air conditioner
Inventor: OZAWA TETSURO
IPC: F24F13/22
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of dew condensation without pasting an insulating material on the side of an air supply passage of a bucket by forming a flow passage which distributes drain water between a third wall provided between a first wall and a second wall and the first wall. SOLUTION: During cooling operation, dew condensation is generated in a heat exchanger where drain water is produced and drops. The drain water W collected on a rear side drain pan 6b located in a higher elevation than a front side drain pan 6a flows along the flow passages of a right bucket 30a and a left bucket 30b and is collected in the front side drain pan 6a. The collected water is drained outside from the front side drain pan 6a collectively and processed. Since the drain water W, which flows from the rear side drain pan 6b to the front side drain pan 6a, is positioned so that a drain outlet of the rear side drain pan 6b may be opposed to the flow passage, and a flow passage P flows between a first wall 31 and a third wall 33 so that the drain water W may not cool the second wall 32.  Therefore, no condensation is generated on a wall surface 32a on a flow passage 17 of the second wall 32.
