IPC: B65G47/22
Filed: 1986-05-16
Abstract: PURPOSE:To change the posture of a plank from the horizontal condition to the vertical condition or in that reverse by arranging a chain conveyor having a holding body free in vertical rocking, at the side part of a horizontal transfer belt and so arranging the constitution that it transfers a plank end part with the holding body and transfer it. CONSTITUTION:A plank 1 is transferred, while being sent by the specified interval, on a transfer belt 2 to a release mechanism 13. When it reaches the release mechanism 13, the end of the plank 1 advances into between the holding parts of a holding body 9 opened by the release mechanism 13. And when it passes by the release mechanism 13, the holding body 9 closes to hold the end of the plank 1. Next the plank 1 is gradually made to erect by an inclined conveyor 17 and shifted while being hung to a chain conveyor 6 through the holding body 9 and finally it becomes hung down vertically and is transferred by the chain conveyor 6. By this constitution, the posture of the plank can be changed automatically and steadily.

Title: Solder feeding method to printed wiring board
Inventor: WAKIHARA YOSHINORI
IPC: H05K3/12
Filed: 1993-05-14
Abstract: PURPOSE:To lessen a cost of feeding solder to the mounting pad of a semiconductor package and to enable an adequate amount of solder to be fed through reflow in a reflow oven of usual oxidizing atmosphere using cream solder applied to the mounting pad of a chip component or the like. CONSTITUTION:Cream solder 9 is applied by printing to a mounting pad 4 of a semiconductor package provided with leads by the use of a metal mask 6 provided with slits 7b which extend along the rows of leads. Thereafter, flux is fed over the cream solder 9, and a printed wiring board 1 is heated to make cream solder 9 reflow. By this method, even if cream solder 9 is made to reflow in an oxidizing atmosphere, an oxide film formed on the surface of a mounting pad 4 of a semiconductor package is removed off by flux, so that a special reflow oven wherein a non-oxidizing atmosphere such as an N2 atmosphere is kept can be dispensed with. As flux is fed over cream solder 9, cream solder of the same composition with cream solder used for mounting a chip component or like can be employed.

Title: Roller type developing head
Inventor: NISHIKAWA MASAHARU
IPC: G03G15/10
Filed: 1990-04-27
Abstract: PURPOSE:To prevent the generation of developing unevenness and to simply maintain a developing gap by means of a compact developing roller to be easily worked by forming many grooves with a prescribed inclination on the developing roller and allowing the head parts of the groves to contact with a recording medium sheet. CONSTITUTION:Many grooves having array pitch P and circumferential length L are formed along the peripheral face of the developing roller, the inclination of the grooves is set up to Np/L (N>=2) in almost areas and the head parts of the grooves are allowed to contact with the recording medium sheet. Thereby, the inclination angle of a locus in an area having unsufficient developing action is increased to narrow the wide and areas having sufficiently clear developing action are overlapped to each other, so that an image having no developing unevenness as a whole can be formed. Since the directions of the grooves are arranged along the rotational direction of the roller, the replacement of a developer on the surface of the roller can be effectively executed, and since the sheet is positioned by the recessed parts of the grooves, the developing gap can be stably maintained and the sheet can follow the compact developing roller to be easily worked even when the roller is bent.

Title: Precision cutting device
Inventor: MOTONISHI SUGURU
IPC: B23Q15/02
Filed: 1988-05-09
Abstract: PURPOSE:To realize a high-precision fine groove working by constituting so that the applied voltage to a piezoelectric element is controlled in response to the detected value of a displacement gauge which has been fitted to a fine groove working tool for measuring the gap dimension between the surface of a workpiece and the end thereof. CONSTITUTION:In a tool T, a capacitance type displacement gauge 18 is fitted to the shank thereof, and at the time of cutting, the gap dimension between the end of the displacement gauge 18 and the surface of a workpiece W is measured for detecting the surface run-out of the workpiece W. This detected signal is arithmetically processed, and the applied voltage to electron ceramics is controlled so as to control the deflect on of the edge part of the tool T in response to the magnitude of the surface run-out. In other words, when the gap dimension is decreased, the applied voltage is lowered in correspondence to the value to shorten the electronic ceramics, and conversely when the gap dimension is increased, the applied voltage is raised to lengthen the electronic ceramics. Thus, even if the surface run-cut due to the rotation of the workpiece W is caused, while absorbing this, a given depth of cut can be maintained for cutting.

Title: Magnetic disk device
Inventor: KANEKO TAKESHI
IPC: G11B33/14
Filed: 1980-08-19
Abstract: PURPOSE:To shorten the time of the warming-up operation of a magnetic device which requires the warming-up operation by sending hot-air from a hot air generator into the device when the disk device is acturated and by stopping the hot-air generator on detecting the temperature of mechanism parts of the device reaching a prescribed value. CONSTITUTION:To the magnetic disk assembly 2 of a magnetic disk device requiring warming-up operation, hot-air from a hot-air generator 7 is blown through a primary filter 5, a blower 4 and a secondary filter 6. The internal and external temperatures of the base disk 1 of the magnetic disk device are detected by a base disk temperature detecting element 8 and an external temperature detecting element 9 respectively and inputted to a temperature-difference detecting circuit 10. When the difference between the temperature of the base disk 1 and the external temperature has the best value, the detecting circuit 10 sends the command of stopping the hot-air generator 7 to a hot-air generator control circuit 11. Consequently, the time of warming-up operation is shortened and a position shift of a magnetic head from the track position of the disk right after the actuation of the device due to the difference in temperature among the internal mechanism parts of the device is corrected.

Filed: 1981-07-21
Abstract: PURPOSE:To suppress the generation of torque pulsation on the brushless motor even when it is operated at a low speed by a method wherein a resistor, having the prescribed value equal to or higher than the DC resistance value of armature coils, is commonly connected in series to each armature coil. CONSTITUTION:When the motor is started or it is operated at a low revolution speed, a resistor 10 is connected in series to armature coils 7-9, because the output signal of a level judging circuit 13, wherein a speed detecting signal sent from a frequency generator 12 will be inputted, is in a low level and a transistor 11 is in OFF position, and, accordingly, the variation in resistance value of the armature 7-9 is absorbed and no torque pulsation is generated, because the resistance value of the resistor 10 is considerably larger than that of the armatures 7-9. Subsequently, when the revolution speed of the motor is increased to the prescribed high speed, the output signal of the level judging circuit 13 is turned to the high level, ON position is given to the transistor 11, and the resistor 10 is short-circuited.
