Title: Reflow device
Inventor: GOTO TADASHI
IPC: B23K1/008
Filed: 1994-07-05
Abstract: PURPOSE:To suppress inert gas flow from a furnace main body by mounting a labyrinth at the entrance and exit of the furnace permitting free vertical movement so as to vertically face one another by sandwiching a conveyer and vertically moving it to a position corresponding to the mounting height of parts on the printed board passing through the entrance and exit of the furnace. CONSTITUTION:When a printed board 1 comes close to the furnace entrance 11, a sensor 25 detects information of the mounting height of a mounting component. When a control part 30 catches such information, an actuator 41 is driven, and a top labyrinth 21-1 on the furnace entrance 11 is permitted to ascend or descend to a position that corresponds to the mounting height of the highest mounting component 2B. Therefore, the printed board 1 is carried into an atmosphere furnace main body 10 through the vertically small space between the top and bottom labyrinths 21-1 and 21-2 and the furnace entrance 11. When the printed board 1 comes close to the furnace exit after reflow soldering, a sensor 26 detects in the same manner, and a top labyrinth 21-2 is controlled to position according to the mounting height of the highest mounting component 2B.

A liquid refrigerant passed through a refrigerant inlet pipe 19 and entered an inlet header pipe 17 is divided to flow from a lower part of a refrigerant passage member 15 into several longitudinal passage 16. Thermal transmitting fins 22A and 22B may transmit heat from combustion gas within a hot gas passage 12 to the refrigerant passage member 15 and then the refrigerant within the longitudinal passage 16 of the refrigerant passage member 15 is sufficiently heated. A liquid refrigerant may start its gasification and evaporation to become a gas-liquid two- phase state. Generated bubbles ascend within the passage 16 formed in a longitudinal direction from a lower part to an upper part. The combustion gas transmits heat to the refrigerant through a hot gas passage 12, so that the refrigerant is uniformly evaporated.

IPC: B62D1/04
Filed: 1984-07-24
Abstract: PURPOSE:To obtain a light-weight steering wheel having practically sufficient tortional rigidity by applying in advance a tortional force in the same direction as external force to one-way oriented fibers. CONSTITUTION:A rotary tool 9 is turned to rotate a winding tool 5 in the direction of arrow, and fibers 2 impregnated with a resin are wound around the tool 5 once. Afterwards, the fibers 2 are wound around a boss tool 11 through notches 8. The processes are repeated to laminate a given number of fibers 2 to form a core material 1. After lamination, the tool 9 is removed out, the boss metal tool 11 is turned, and the fibers 2 in the spoke portion 4 are twisted toward one direction which coincides with the direction of distorting the spoke portion 4 by external force, where the left and right sides are in the opposite directions. The core material 1 is heated to harden the resin in such a way as to prevent the restoration of twist, the metal tool 11 is fixed, and the core material 1 is covered with resin and molded at a give temperature and under a given pressure to obtain a product. By adding the twisting' process, the tortional rigidity of the core material can be raised, enabling it to overcome tortional torque to be generated by external forces.

Filed: 1989-06-14
Abstract: PURPOSE: To achieve the non-contact measuring method of a surface for measuring an arbitrarily formed surface accurately and inexpensively by measuring the interval of a reference contour from the measurement range of the surface while measuring it by an interferometer and determining each different between a measurement value and a target value. CONSTITUTION: First, the reference contour of at least one reference element essentially corresponding to the measurement range of a surface is measured by an interferometer regarding a known standard contour where an external form is known within the allowable range of the surface. Then, a surface to be measured is moved to a position that is limited in terms of space regarding a reference element. Then, the interval of the reference contour from the measurement range of the surface is measured while being increased from the interferometer and each difference between a measurement value and a target value is determined, thus measuring the actually measured contour of the work surface and at the same time controlling a machining tool during process until a desired target contour is obtained in some cases.

Title: Printer
Inventor: MORIKAWA SAICHI
IPC: B41J29/46
Filed: 1989-06-15
Abstract: PURPOSE:To allow the presence of an additional unit to be checked easily by prining the presence of the additional unit with an expansion of a test printing function. CONSTITUTION:A printer device is often used by a large number of unspecified persons, so that the presence of an additional unit needs to be checked. To meet this requirement, the presence of a connected additional unit is determined by printing it in the test printing section of a printer. If test printing is performed by setting FORM LENGTH, that is, a form length switch to 00 line on a control panel, a connected additional unit is indicated in the latter half of test printing process. If FORM LENGTH is set to any other line than 00, a routine test printing is performed. Consequently, if the presence of an additional unit need not be determined, it can be confirmed by manipulation of an operator.

Abstract: PROBLEM TO BE SOLVED: To reduce-high-frequency noise of a solid-state blue laser device. SOLUTION: The output light of the solid-state laser light source 1 is taken out as a desired light output 6 through an optical modulator 4 having a diffracting function and a part of the output of the solid-state laser light source 1 is converted 7 into an electric signal which is added to the said optical modulator to separate the light of a high-frequency noise component to a different direction from the said desired light output. This solid-state laser device divides 8 a part of the output of an optical detecting circuit 7, differentiates a part of the rest by a differentiating circuit 9, separates a rise and a fall of the noise of the differentiated signal by half-wavelength rectifier circuits 10 and 11 and adds them to the divided noise by an adding circuit 1 to approximately advance the phase of a noise waveform and to correct the delay of the optical modulator 4.

IPC: G07C7/00
Filed: 1983-08-24
Abstract: PURPOSE:To eliminate the need for a backup battery by storing ROM with data integrated so far when electric power is not supplied any more. CONSTITUTION:When a power switch 2 is turned on, a control part 42 transfers the contents of EEPROM (ROM where integrated data is readable and writable) 5 to a memory 43. A counter 41 counts the time at specific intervals of time, and the count result and the contents of the memory 43 are added together by an adding circuit 44, whose result is stored in the memory 43 and also displayed on a display device 6. When the power switch 2 is turned off and the output of a power source circuit 3 decreases to a specific value, an output signal appears at a terminal 3c to allow an interruption to the control part 42. The control part 42 writes the data from the memory 43 in EEPROM5 before the voltage supplied to a terminal 42a drops to the 2nd specific value.
