Patent JP-H01135583-A (JP)
Title: Water purifier
Inventor: WATANABE TORU
IPC: C02F1/28
Filed: 1987-11-20
Abstract: PURPOSE:To enable an automatic removal of impurities attached to the surface of a porous hollow yarn, thereby reducing the clogging thereof so that favorable cleaning functions can be maintained for a long period of time, by providing a particle-driving means to move particles, which comes freely in contact with porous hollow yarns, between the porous hollow yarns. CONSTITUTION:Raw water for waterworks is purified by passing it through activated carbon 5 and porous hollow yarns 4 and delivered from a delivery port 14 as treated water. And the activated carbons 5 which have come into a cylinder 3 are caused to rise up and move between the porous hollow yarns 4 due to the change in pressure (a kind of means to drive particles) caused by the operation of water lines. As a result, the activate carbons 5, as particles 6, are brought into contact with the surfaces of the porous hollow yarns 4, causing impurities 9 contained in the raw water, which have attached to the surfaces of the yarns 4, to be cut off. In this manner, clogging of the yarns 4 is eliminated and water purification function can be favorably maintained for a long period of time.

Title: Semiconductor device
Inventor: YAMAJI YASUHIRO
IPC: H01L23/50
Filed: 1985-12-26
Abstract: PURPOSE:To prevent exfoliation between an outer lead and a package by making small the cross-sectional area of the bent portion of the outer lead so as to facilitate the bending of the outer lead. CONSTITUTION:An outer lead 12 provided continuously to an inner lead extends outside of a package 11, and the portion of the outer lead in proximity to the package 11 is to be bent downward along the lateral side of the package 11. In this portion to be bent, an indentation 13 is so formed that said portion is thinner thereat than the other portion of the outer lead 12. The indentation 13 is a lateral groove formed in the direction perpendicular to the longitudinal direction of the outer lead 12, and the cross-sectional area of the portion to be bent is smaller than that of the other portion owing to the formation of the lateral groove. Therefore the strength of the portion to be bent is smaller than that of the other portion, and thus it can be bent easily by a bending stress. This indentation 13 can be formed easily by half-etching the portion to be bent on the occasion when a lead frame is etched.

Title: Semiconductor integrated circuit device
Inventor: YAMAMOTO YASUNARI
IPC: H01L27/04
Filed: 1990-10-31
Abstract: PURPOSE:To reduce the power loss of a current control circuit by connecting a current control and a detection transistor(TR) whose drain electrode is connected to an external terminal to an open drain terminal and connecting an overcurrent detection resistor to a source electrode of the detection TR. CONSTITUTION:An L level signal is inputted to an input pin 13, a PMOS TR T1 in a buffer circuit 11 is turned on, an NMOS TR T2 is turned off and an H level signal is inputted to a base terminal of DMOS TRs T3, T5 via an output signal line 14. The T3, T5 are turned on an a load 17 is driven by an external power supply 16. When an overcurrent 10 flows to the load 17, since a voltage detected across a resistor R1 connected to a point C exceeds a voltage Vs, an H level signal is inputted to a base of a TR T4. The TR T4 is turned on, the level of the signal line 14 goes to L, the TRs T3, T5 are turned off and the overcurrent 10 flowing to the load 17 is interrupted. Thus, the detection voltage at the point C is lowered and when the detection voltage reaches a reference voltage VS or below, a comparator CM outputs an L signal to a base of the TR T4, which is turned off. Then the TRs T3, T5 are turned on.

IPC: F25D23/06
Filed: 1989-11-13
Abstract: PURPOSE:To perform integration of a panel and to simplify the panel by forming a suction port as an air flow opening between a guide surface formed of bending of the panel and the upper part of a front surface of a cold storage box body. CONSTITUTION:A catcher 27 is secured to the front surface of an angle 10 corresponding to a striker 20 protruding rearward from a cover 18, and the striker 20 is engaged with the catcher 27 to complete mounting of a decoration panel 11. A suction port 28 is formed as an air flow opening between the guide surface 16 of a panel 12 and the upper part 2A of the front surface of a storage box body 2. The panel 11 is mounted on the front surface of a machine room 6 and the room 6 is so covered by the panel 11 as not to be completely seen the interior. Since the port 25 is formed under the panel 11, suction of the air becoming a high temperature due to heat exchange with a condenser 7 is remarkably reduced to improve the heat exchanging efficiency.

Title: Automatic cash transaction device
Inventor: GOTO YASUO
IPC: G06Q20/00
Filed: 1989-11-15
Abstract: PURPOSE:To improve the operating efficiency of an automatic cash transaction device by attaining an off-line exchange process of notes or coins in the waiting time for on-line communication with a center at bank transaction for reception/ payment of cash. CONSTITUTION:When a customer selects an exchange process via a customer operation part 3 during the communication with a center, a main control part 1 initializes a note input/output part 4 or a coin input/output part 5 so as to perform the exchange process in parallel with the communication with the center. For instance, the customer wants to exchange the notes for the coins and puts the notes into the part 4. Thus the part 4 confirms the types and the number of sheets of these notes. Then the main control part 1 produces a payment instruction to the part 5 to comply with the desired types and the number of sheets inputted from the customer via the part 3. Thus the part 5 discharges the coins in response to the received instruction. In such a constitution, the customer can apply an off-line exchange process during the on-line communication with the center. Thus the cash transaction processing time is shortened.

Title: Paper posterior processor
Inventor: IKOMA AKIRA
IPC: B65H29/18
Filed: 1998-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a paper posterior processor that can stack output paper on a paper delivery tray in an orderly fashion even when used with copying machines or printers having a higher paper processing speed. SOLUTION: A low-speed roller 16 is disposed in addition to a paper delivery drive roller 25 for discharging paper to a paper delivery tray 12, and is slightly offset from the paper delivery drive roller 25. For discharging paper, the paper delivery drive roller 25 is decelerated only to transfer the trailing edge of paper only by a slight distance, and the low-speed roller 16 takes over the carrying of paper. The deceleration duration of the paper delivery drive roller 25 thus becomes extremely shorter, so that its normal feeding speed can be made equal to that of copying machines, printers or others and free from speed control.

Filed: 1990-10-31
Abstract: PURPOSE:To prevent the discharge of filter beads outside a tank filter in backwashing by supplying water into the tank filter in the volume smaller than that of the tank filter and allowing the water to stand for a specified time. CONSTITUTION:A filtration circuit 23 provided with a tank filter 22 packed with filter beads is connected to a circuit 2 for circulating the hot water in a bathtub 1. A backwashing water discharge circuit 24 is branched from the filtration circuit 23 on the upstream side of the tank filter 22, and a backwashing circuit 30 is connected to the filtration circuit 23 on the downstream side of the tank filter 22. The backwashing water is refluxed to the tank filter 22 from the backwashing circuit 30 by a control part and then sent to the water discharge circuit 24 to backwash the tank filter before the hot water flowing in the circulating circuit 2 is filtered. Meanwhile, water is supplied into the tank filter 22 in the volume smaller than that of the tank filter 22 and allowed to stand for a specified time prior to backwashing. Consequently, the filter beads are not discharged outside the tank filter in backwashing.
