Title: Method of soldering printed wiring board
Inventor: KONDO KENJI
IPC: H05K3/34
Filed: 1987-07-10
Abstract: PURPOSE:To enable the perfect soldering of chip parts on a printed wiring board, by setting the direction of transferring the board as an oblique direction in the horizontal plane with respect to the flow direction of melted solder fluid, and inclining the board at a desired angle in the vertical plane perpendicular to the transferring direction of the board. CONSTITUTION:A solder reservoir 31 is divided into two reservoirs by a separating wall 32 arranged at the central part, and arranged in order in the transferring direction (arrow A1 direction) of a printed wiring board 1. In jetting reservoirs 37, 38 installed in a first reservoir 33 and a second reservoir 34, melted solder fluids 35, 36 are pressurized by driving a motor, and compulsorily jetted. A jet nozzle 40 and a jet fluid 41 are inclined at an angle of theta1, in a horizontal plane to the transferring direction A1 of the printed circuit board 1. Chip parts 3 are mounted on a rear conductor surface. When the board travels in the transferring direction A1 while ascending, the locus wherein the conductor surface 2 inclined at an desired angle theta3 in a perpendicular direction to the transferring direction A1 comes into contact with the melted solder fluid, is made horizontal. Thereby, the soldering with uniform height H1 with respect to the melted solder fluid is enabled.

Title: Temperature compensating circuit for ammeter
Inventor: HARIGAYA ISAO
IPC: G01R19/32
Filed: 1981-10-26
Abstract: PURPOSE:To reduce the exposure error in a wide range from a low temperature to a high temperature, by inserting a series or serial-parallel resistance circuit including a thermistor in a DC ammeter as an exposure controller for a camera or the like. CONSTITUTION:When a power switch S1 is turned on, the voltage of a power source battery E is supplied to an exposure circuit through a constant voltage circuit RF, and a current is flowed to an ammeter ME through a photodetector RX. The aperture value of a lens is determined on a basis of the deflection angle of the needle of the ammeter due to this current value. In respect to correction of a temperature compensating circuit, values of resistances R1 and Rs are selected so as to make equation true, thus minimizing the exposure error agaist the variation of temperature in a wide range from a low temperature to a high temperature. In equation, Me, R1, Rs, and Rso are the winding resistance value of the ammeter, the resistance value of a correcting resistance, the resistance value of a thermistor, and the resistance value of the thermistor at a normal temperature respectively.

Title: Tool attaching device
Inventor: IMAI TOMOYASU
IPC: B23Q17/12
Filed: 1989-07-04
Abstract: PURPOSE:To improve the machining precision and to prolong the service life preventing the breakage of a tool by providing a control device to decide the magnitude of vibra tion of the dividing position of a tool by means of measurement during rotation of a main shaft equipped with a tool. CONSTITUTION:In a state in which a tool is attached, a main spindle 2 is rotated and vibration during rotation is measured by a measuring device. The measurement is compared with a reference value set at a control device 23, and when it is decided that it is lower than the reference value, machining is effected as it is. If it is judged so that it is higher than the reference value, the dividing position of a tool is varied by a given angle with the main spindle 2 by means of a dividing mechanism to measure vibration during rotation of the main spindle 2. A position the measurement of which is lower than a set value is selected to perform machining. Otherwise, vibration during rotation of the main spindle is measured in a plurality of positions where the tool is varied by a given angle with the main spindle 2, the measurement is compared with the reference value by the control device 23, and a dividing position where mea surement is minimum is selected to effect machining. This constitution selects the dividing position of the tool to a relation in which vibration is low enough for offset of an unbalance between the main spindle and the tool and effects machining.

Filed: 1986-07-23
Abstract: PURPOSE:To detect an exciting rush current by providing a search coil which has a magnetic core nearby the iron core of a transformer and comparing its output with a specific reference value. CONSTITUTION:Iron cores 1-1 and 1-2 of a shell type transformer are wound with a high-voltage coil 2 and a low-voltage coil 3 and the search coil 4 is placed nearby the iron cores. The rush current, magnetic flux, and magnetic field (corresponding to the magnetizing force of iron core) when the transformer is in an unloaded state from the high voltage side are denoted as iH, phi, and H. When a voltage is a sine wave, the magnetic flux phi is a sine wave as well, but the magnetic field H is a distorted wave because of nonlinear characteristics of the iron cores. The output E of the search coil has specific relation to the number N of turns, coil sectional area S, the magnetic permeability mu of the iron cores, and the magnetic field H and the output of the search coil has similar relation and is hundreds of times an output in a steady state. For the purpose, a detection reference voltage EL is determined based on the generated voltage Em of the search coil 4 with the maximum value of the voltage in the steady state to detect the rush current clearly at a high speed.

Abstract: PURPOSE:To stabilize the operation of the device having a gate electrode of high- melting metal by reducing a movable ion in an oxide film to less than PSG. CONSTITUTION:At the stage where a gate oxide film or a field oxide film is formed on an Si substrate, O2 plasma processing is performed. As the result, material capable of liberating the movable ion in the oxide film is activated and actualized as the movable ion. After that, a gate electrode of Mo is formed and covered with PSG. Then the movable ion moves to PSG, at the part of the gate, through the intermediary of an Mo film and is subjected to gettering, while it moves directly to PSG at the part of the field to be subjected to gettering, and the amount thereof is much larger than that in the case when the substrate is covered simply with PSG, and thus the property of the device is fully stabilized.
