Title: Metal mask for printed circuit board
Inventor: YAMAZAKI TAKASHI
IPC: H05K3/12
Filed: 1994-09-22
Abstract: PURPOSE: To accurately form solder bumps on lands by making the diameters of holes for printing solder provided through a metal mask smaller than the diameters of the lands on which solder is printed. CONSTITUTION: Holes 2 for printing solder of a metal mask 1 and lands 4 on a printed board 3 are alighted with each other, solder bumps 5 are formed on the lands 4 by printing solder on the lands 4 through the holes 2. Since the diameters L3 of the holes 2 are made smaller than the diameters L2 of the lands 4, all amount of the solder is printed on the lands 4 and the solder does not protrude from the lands 4 even when the holes 2 are somewhat deviated in position from the lands 4. When reflow soldering is performed after putting the terminal sections of a BGA 6 on the bumps 5, the BGA 6 is completely connected to the printed board 3.

Title: Ice heat accumulator
Inventor: WATABE MASAHARU
IPC: F24F5/00
Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To increase the storage amount of ice by a method wherein circulating chilled water is supercooled by a supercooler and sprayed over the water surface of a heat accumulation tank. SOLUTION: A refrigerant 2 cooled by a refrigerating machine 3 is sent to an ice-making coil 4. Water in a heat accumulation tank 1 exchanges heat with the refrigerant 2 via the ice-making coil 4 and ice with no fluidity is produced around the ice-making coil 4. The refrigerant 2 flowing out of the ice- making coil 4 is sent to a supercooler 6 after its temperature is controlled by a temperature controller 13 and exchanges heat with chilled water 14 there to produce supercooled water 15. The supercooled water 15 is sprayed into the heat accumulation tank 1 via a nozzle 7 and released from the supercooled state, causing a portion of it to turn into ice with fluidity. As the chilled water 14 flowing out of the heat accumulation tank 1 contains ice cores, a filter 11 and a heater 12 are installed in a chilled water pipeline 10 to prevent the ice cores from entering the supercooler 6.  The refrigerant flowing out of the supercooler 6 is sent to the refrigerating machine 33 and cooled again. Those actions described above are continuously carried out to accumulate ice in the heat accumulation tank 1.

Filed: 1990-08-30
Abstract: PURPOSE:To make the difference in delay time in bus lines having a fixed bit width negligible even when the layout of an integrated circuit is decided without paying attention to the balance in wiring capacity of the bus lines by cutting bus lines between macros having different sizes at every fixed length and automatically connecting bus buffers of the same number as that of the bus lines, and then, wiring the outputs of the bus buffers as bus lines between macros.

Abstract: PURPOSE:To perform a magnetic recording based on the following information by providing a shifting register at the position corresponding to the feeding position of a body to be examined and by writing the information at the bit position of the shifting register corresponding to the treating time thereof in case of the different processing time being required for the different sort of detecting signal. CONSTITUTION:When the flaw part of a zinc plated plate 13 reaches the position of a laser detecting part 16, a detecting part 16 memorizes the full length counter G as G1 with its reading. Thereafter the detecting part 16 performs the treatment corresponding to the sort of flaw and its condition and when the decision is made that the flaw is harmful to the plate 13, it outputs a detection signal D. Then when the writing part 18 receives the signal D, the counter G is memorized as a reading G2. With finding then the difference in the G2 and G1 to which zone is the flaw of the plate 13 progressing presently is known. The digital signal of the level (1) is written then in the bit position of the shifting register 17 corresponding to said zone. The writing position to the bit position of the shifting register 17 is thus controlled selectively according to the unfixed processing time for the signal D like this.
