Title: Bath water purification apparatus
Inventor: IWATA YASUSHI
IPC: C02F1/78
Filed: 1999-10-08
Abstract: PROBLEM TO BE SOLVED: To prevent a filter medium inside a purification barrel from wearing out, controlling fouling of the piping by mixing sufficient quantity of gas in bath water. SOLUTION: An ejector 5 for mixing gas in bath water is mounted between a purification barrel 4 and a circulation pump 3, and gas is mixed in the bath water purified by the purification barrel 4 and sucked by the circulation pump 3. Therefore, the bath water containing the gas is prevented from passing through the purification barrel 4 and a filter medium mounted inside the purification barrel 4 is prevented from wearing out. Since the sucking side of the circulation pump 3 is always at a negative pressure when the circulation pump 3 is operated, a sufficient quantity of gas can be mixed in the bath water by the ejector 5 by disposing the ejector 5 on the sucking side of the circulation pump 3 even if the flow of the bath water flowing through a water pipe 2 is reduced because of, for example, adhesion of the scale to the pipe.

Title: Method for forming temporary bonding between semiconductor die and board
Inventor: SUCHIYUAATO II GURIAA
IPC: G01R1/073
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To form a tentative bonding between a solder bump on a semiconductor die and a metal paste on a board. SOLUTION: Small spherical lumps 44 which form metal paste 42 are applied on a contact pad 40 on a board and heated so as to be partly melted. By this setup, small spherical lumps 44 are bonded to the contact pad 40, and the adjacent spherical lumps 44 are bonded to each other. In succession, a die where bumps are formed is arranged on the small lumps 44 and heated at a minimum temperature just high enough to partly melt the small lumps 44 to form a local adhesive bond. A metallurgical contact region between the small lumps 44 of paste and the bumps is reduced to an irreducible minimum, whereby an electrical contact small in cross section is kept between the small lumps 44 and the bumps, and an interconnection electrically film but physically weak is established between a semiconductor die 32 and a board 38.  The semiconductor die 32 is connected to the board 38 once, the semiconductor die 32 is checked and subjected to burn-in, and even if it is dismounted later, the bumps are hardly damaged.

Abstract: PURPOSE:To make it possible to apply the present image processor for each image area of copying machine to general variable density original copies or to color original copies without damaging original copies by selecting one from a plurality of types of image processing by an image processing means with the aid of a combination of signals generated by an automatic image area recognizing means and an image area specifying means. CONSTITUTION:To automatic image area recognizing circuit 30, a RGB image signal S1 is input from scanner 1, and the character part of an original picture outputs 0, while a variable density image part of the original picture outputs 1 as a recognition signal S21. Thereafter system controller 5 loads image area specifying circuit 32 with area shape data and area number. To the image area specifying circuit 32, a synchronous signal LSYNC and a video synchronous signal VCLK in unit of picture element are input for each scanning line, and the image area specifying circuit 32 counts these input signal to specify the present original picture scanning position, and outputs an area identification number set previously corresponding to coordinates of the present original picture scanning position as signal S22. Image processing selecting circuit 33 is a combination of logic circuits to which signals S21 and S22 are input and from which a one-bit signal S22 is output. Accordingly, the image processing selecting circuit 33 can be realized using lookup table and a single output can be determined by a combination of signals S21 and S22.

IPC: F16H3/08
Filed: 1991-08-14
Abstract: PURPOSE:To promote the miniaturization and lightweightness of a device by installing an intermediate shaft in the midway between a main shaft and a driving shaft set up in parallel with each other, setting the number of a gear and a clutch on the main shaft down to two pieces each, and preventing a gear on the driving shaft from enlargement in size. CONSTITUTION:A main shaft 5, an intermediate shaft 9 and a driving shaft 13 set up in parallel with one another are installed in an automatic transmission, while a gear 7 and another gear 20 are set up on this main shaft, and four gears 10, 15, 21, 22 are set up on the intermediate shaft 9. In addition, gears 12, 17, 25 are set up on the driving gear 13. Then, clutches 6, 18 are operated on the main shaft 5 and a one-way clutch 41 and clutches 18, 24 on the driving shaft 13, respectively, and they are interlocked with respective gears, thus six- speed gearshifting can be done in this way. In this connection, gears 7, 12, 15 are made floatable via ring shafts 8, 14, 16, and the gears 20, 22 are also made floatable via ring shafts 19, 23. Thus, the gears 12, 17, 25 on the driving shaft 13 are six-speed gearshifted, and each gear on the intermediated shaft 9 and the driving shaft 13 can be diametrally miniaturized, and besides, made lighter in weight.

Title: Game ball receiver
Inventor: MIWA MINORU
IPC: A63F7/02
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To smooth the flow of game balls near the inflow port of a game ball receiver. SOLUTION: Since a branching gutter 10 is provided with a triangular projection 13 on the upper surface of a slope 12, the game balls flowing from a replenishing gutter and hitting the projection 13 on the slope 12 irregularly change their advancing directions and flow from various directions into an inflow port 18. Namely, the game balls are scattered by the projection 13 and flow in average over all the area of the inflow port 18. Therefore, the game balls are not concentrated at one position of the inflow port 18 or inside/outside it, the game balls smoothly flow from the replenishing gutter into the branching gutter 10. Thus, the inflow of game balls from the inflow port 18 is made speedy and in order to prevent ball clogging near this port, it is not necessary to enlarge the branching gutter 10 by widening the width of the inflow port 18 or the like.

Title: Data imprinting device
Inventor: ITO KENJI
IPC: G03B17/00
Filed: 1986-12-05
Abstract: PURPOSE:To minimize the abnormality of a series of data to be imprinted in one frame by interrupting one-character formation when a pulse output for next one-character formation is inputted in the middle of the one-character formation, and starting the next one-character information immediately. CONSTITUTION:When one new pulse is inputted from a film position detecting means 201, a light emission control means 202c detects whether or not one- character formation based upon a previous pulse input is performed by an imprinting instructing means 202b and a data imprinting means 204. Then when it is judged that the last one-character formation is not completed although the signal indicating the start of the next one-character formation is inputted, the operation of the data imprinting means 204 is interrupted immediately through the imprinting instructing means 202b so as to stop the character formation even in the middle. Consequently, such a problem that the moving speed variation of a film increases in the middle of imprinting operation and character formation after a signal instructing the start of the one-character formation is inputted in the middle is not performed normally is minimized.
