Title: Printed circuit board
Inventor: TAGUCHI KATSUICHI
IPC: H05K1/11
Filed: 1990-01-29
Abstract: PURPOSE:To obtain a printed circuit board capable of suppressing production of solder bridges which need correcting by making linearly-arranged lands, which consist of a plurality of lands, on a soldered face and auxiliary lands adjacent to terminal lands at both ends of the linearly-arranged lands. CONSTITUTION:A plurality of lands 4 on the soldered face of a printed circuit board 1 are arranged on the same straight line as parts insertion holes 2 to form two lines of linearly-arranged lands on the soldered face. One round auxiliary land 6 is arranged adjacently to every terminal lands 5 at both ends of the linearly-arranged lands. Therefore, even if flow soldering is performed by moving the printed circuit board 1 in the direction of A or B, when an IC 3 is mounted the rate of production of solder bridges between the auxiliary lands 6 and the adjacent terminal lands 5 heightens and production of solder bridges between the lands 4 corresponding to the parts insertion holes is prevented. Thereby the production of solder bridges at where solder bridges need correcting is prevented and correction of solder after completion of flow soldering is decreased.

Title: Evaporating dish for refrigerator
Inventor: MAEDA KOJI
IPC: F25D21/14
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide an evaporating dish which speeds up evaporation concerning the evaporating dish in a machine room. SOLUTION: Defrosting water is stored into a first water storage part 8 formed on the arched top part of a compressor and an overflow of water from the first water storage part 8 is stored into a second water storage part 9 which is separated from the first water storage part 8 by a section wall 7 and formed on the outer circumference of the first water storage part 8. The second water storage part 9 is arranged at a position shifted to the outer circumference from the top part of the compressor. Therefore, the evaporation from the first water storage part 8 which makes it easy to receive heat from the compressor is so arranged to occur earlier than that from the second water storage part 9 which makes it hard to receive heat from the compressor.  This minimizes the evaporation from the second water storage part 9 thereby eliminating matters which adheres onto the bottom of the evaporating dish and causes malodor.

IPC: F16K31/06
Filed: 1987-01-29
Abstract: PURPOSE:To reduce the current when an electromagnet is absorbed, by furnishing an electromagnet to close and open a stop valve, and an absorption current circuit to absorb the electromagnet. CONSTITUTION:By the electric signal of an electric circuit 14, a current to open fully a valve body 11 at the initial current flow is let flow for a specific period. As a result, the valve body 11 pushes the movable part 18 of an electromagnet 17, and makes it contact to the fixed part 21 against a spring 19. In the signal of the electric circuit 14, a pulsating current is superposed on a DC current in the normal condition. By the pulsating current, an AC voltage is generated in a secondary coil 15, in the same theory as a transformer, which is rectified by a rectifier circuit 16, and a current necessary to give the absorbing and maintaining force to the electromagnet 17 is flowing. In such a composition, when the amount of the gas is regulated, the stopping force does not act to the valve body, being effective to reduce the maximum current.

IPC: C23C2/26
Filed: 1983-02-07
Abstract: PURPOSE:To adjust uniformly the transverse direction of a plated surface and to obtain a plated steel sheet having particularly good paintability by passing the hot dipped steel sheet between upper and lower variable crown rolls provided with pressurizing chambers to be acted with oil pressure. CONSTITUTION:An upper roll 3 and a lower roll 3 consituting variable crown rolls are respectively disposed in such a way that the lower side of the former forms a pressurizing chamber 8 and the upper side of the latter forms a pressurizing chamber 8. When a steel sheet 1 plated thereon with Zn, Al or the like is passed through said rolls, the skin pass rolls deform like solid lines 4' but if oil pressure is preliminarily generated in the chambers 8 of the rolls 3, the body parts of the rolls are corrected like dotted lines 4''. The plated surface of the sheet 1 is eventually uniformly rolled down in the transverse direction. The plated steel sheets of various different shapes and materials can thus be pressed uniformly in the transverse direction of the plated surface and therefore the spangle and residual dross on the plated surface are crushed uniformly with one time of skin pass and the surface of the paint coated film is made beautiful in subsequent painting.

Title: Liquid-crystal image display apparatus
Inventor: ONO KIKUO
IPC: H01L27/12
Filed: 1988-02-01
Abstract: PURPOSE:To enhance a yield with a good image quality by a method wherein a holding capacitor electrode is formed by using a structure which is not worked and patterned at least in a substrate region containing a TFT of a display part on an insulating substrate. CONSTITUTION:An electrode 2 is not patterned and worked at least in a display region 9. Because a patterning and working process is not executed essentially, a defect is limited to a point defect even when a defective part of the electrode 2 is produced due to any cause, because the patterning and working process is omitted intentionally. For example, if W2 is 100mm and the number of scanning lines inside the W2 is 500, a voltage drop from a grounding point is inversely proportional to the W2. The holding capacitor electrode 2 can reduce the voltage drop to 1/500 as compared with that of a conventional structure. This effect becomes large when a display apparatus is made to be a large picture size and to be a highly fine picture. Because a resist coating process, an exposure process and an etching process can be omitted, a liquid-crystal apparatus can be obtained essentially at a low cost and at a good yield as compared with an apparatus of conventional structure.
