Title: Method for soldering chip
Inventor: UEDA TAKASHI
IPC: H05K3/34
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for soldering a chip which allows chip soldering to be simplified and thermal damage on the chip to be reduced. SOLUTION: Low-melting-point solder 12, 13 is placed on both the ends of a support 11 composed of high-melting-point solder. The solder 12 on one end is temporarily fastened to a pad 2 on a chip 1 using flux 10, and the solder 13 on the other end is temporarily fastened to a pad 6 on a substrate 5 using flux 9. The workpiece is heated in a furnace, and the solder 12, 13 is thereby melted and solidified to accomplish soldering. Since only one cycle of heat treatment is required, the process can be simplified and thermal damage to the chip 1 can be reduced.

Title: Outer pull type clutch device
Inventor: KAWADA TOMONORI
IPC: F16D13/52
Filed: 1990-01-24
Abstract: PURPOSE:To improve feeling at the time of connecting/disconnecting a clutch by providing a circular tapered surface on one of a pressure plate and a push rod at the connection part therebetween, and thereby eliminating inclination of the pressure plate with a simple structure. CONSTITUTION:A clutch plate 5 and a friction plate 6 are pressurized by a pressure plate 14 under an ON state of the clutch device 1, and torque is transmitted. A rotary shaft 12 is rotated with operation of a clutch lever 13, a push rod 11 is moved in a direction of an arrow (a). The pressure plate 14 is pulled in the same direction, the above pressurizing force is eliminated and torque transmission is inturrupted. In the clutch device 1 of the above-mentioned structure, the push rod 1 is engaged with the pressure plate 14 through a spherical tapered surface 11a-1 and a recessed engagement surface 19a. When the push rod 11 is inclined by the deformation of a clutch cover 10, accompanied by the rotation of the rotary shaft 12, the inclination is not transmitted to the pressure plate 14. Feeling of connecting/disconnecting the clutch is thus improved.

Filed: 1978-02-06
Abstract: PURPOSE: To enable conveying of high temperature material by confirming the safety of hoisting capacity of a hoisting electromagnet having a temperature detector for sensing the temperature of the material to be conveyed.  
     CONSTITUTION: In a hoisting electromagnet 1 having an inner pole 2, outer pole 3, and a coil 4 wound around the pole 2, outer pole 3, and a coil 4 wound around the pole 2, a thermocouple 5 is buried in the recess of certain pole surface as the attracting surface of the pole 2 with lead wires connected to amplifier relay to thus form an alarm circuit at predetermined output value. Thus, when high temperature material to be conveyed is attracted to the electromagnet, the thermocouple 5 produces its output upon reception of high temperature from the material. If the output becomes higher than predetermined value, a buzzer in the circuit rings. Accordingly, it can safely and accurately convey the material by considering the magnetic nature to the temperature of the material.

Filed: 1994-02-04
Abstract: PURPOSE: To provide an easily and inexpensively manufacturable damper assembly. CONSTITUTION: A damper assembly 32 for a friction clutch 30 has a spring pack 42 housed in a spring cage 38. The spring pack elastically connects a pressure plate 34 and an output hub 24. The pressure plate has a friction surface.

A projecting part 52 is formed in the spring cage 38, the pressure plate and the output hub being members of a damper to impart friction hysteresis to these relatively rotating damper members. The normal force for imparting the friction hysteresis is brought about by a washer spring 44 positioned by a projecting part 48 formed in one of members of the damper. Angular displacement allowed by a spring of the damper is restricted by a window 58 formed in one of members of the damper and a tab 60 formed in the other member of the damper.

IPC: G01R31/02
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To enlarge an open stroke, without enlarging a device, so as to facilitate installation and removal of a component mounting substrate, by connecting a first movable base to a second movable base, and a first movable arm to a second movable arm. SOLUTION: When a turning lever is first moved, a connecting shaft 5 directly connected to the lever is rotated.

Title: Magnetic card and method for deciding legitimacy thereof
Inventor: HASHIMOTO JUNICHI
IPC: G11B5/09
Filed: 1990-01-23
Abstract: PURPOSE:To prohibit the forgery and falsification of the magnetic card by providing a magnetic layer which has the coercive force substantially higher than the coercive force of the magnetic layer for recording and a low Curie point and is used as a track for collation. CONSTITUTION:The magnetic card 1 has the magnetic layer 3 which is formed as a stripe on the surface of a nonmagnetic base body 2 and is used as the track for magnetic information recording. The card has the magnetic layer 4 which has the coercive force substantially higher than the coercive force of the magnetic layer 3 at ordinary temp. and the Curie point substantially lower than the Curie point of the magnetic layer 3 and is used as a track for collation on the different surface part. Since this magnetic material has the characteristic of having the high coercive force at ordinary temp. and the low Curie point, the material is not easily available for general people and, therefore, there is no possibility that the cards are reproduced in a large quantity. In addition, the card device requires a thermomagnetic recording means. Thus, the forgery and falsification with commercially marked magnetic card devices are usually infeasible.

Title: Gas-liquid contact device
Inventor: YOSHIMATSU YUKIYOSHI
IPC: B01D3/22
Filed: 1992-01-29
Abstract: PURPOSE:To reduce pressure loss while well keeping gas-liquid contact and to prevent weeping by setting the small holes formed to a perforated plate by punching so that the diameter of each hole on the rear surface side of the perforated plate is larger than that of the hole on the upper surface side thereof. CONSTITUTION:A liquid 3 flows on a perforated plate 2 from the upstream side and gas 4 flows in the perforated plate 4 from below. Small holes 6 are regularly provided to the perforated plate 2 and the lower part of each of the small holes 6 has an opening part 7 having a diameter larger than that of each of the holes 6. The gas 4 and the liquid 3 become a gas-liquid contact state on the perforated plate 2. When the gas 4 flows in the perforated plate 2, the gas 4 can smoothly flow in the perforated plate 2 by the action due to the arrangement of the opening parts 7 and pressure loss at the time of inflow is reduced. Since each of the small holes 6 of the perforated plate 2 has an area having a different diameter in the thickness direction of the perforated plate and increases in its wet length downwardly, weeping is unlikely to generate and an operation range can be widened.

Abstract: PURPOSE:To make the toasting condition constant even though some voltage variation is generated, by inputting the voltage variation correcting coefficient responding to the voltage difference to a microcomputer so as to extend and control the heating time when the voltage obtained by a voltage detecting element to detect the received voltage is less than a specific value. CONSTITUTION:When the oven range operates to toast, a toast key 5 on an operation board 4 is pushed after a bread is laid in a container 2, and thereby, the received voltage is measured by a voltage detecting element only for two seconds. The measurement value is input to a voltage comparator to compare the voltage there, and when the voltage is out of the scope from 90V to 100V, the output of 90V is given to a memory element if it is less than 90V, while a signal indicating 100V is output to the memory element if it is not less than 90V. The temperature in the container 2 is measured by a container temperature detecting element, and said voltage value when the value of the memory element is less than 100V is given to a voltage variation correcting device. As a result, a voltage variation correcting coefficient responding to the voltage difference is input to a microcomputer, and the heating time when the container temperature is t deg.C is extended and controlled, and the heating is started.
