Title: Nozzle for constant quantity discharging device
Inventor: SAITOU SUSUMU
IPC: G01F15/02
Filed: 1983-03-24
Abstract: PURPOSE:To obtain a contant quantity discharge device, which is not affected by the change in temperature, by providing a dual structure, wherein a material having a small thermal expansion coefficient is used for an outer pipe and a material having a large volume expansion coefficent is used for an inner pipe, and automatically changing the cross section of a nozzle hole in correspondence with the change in temperature of discharging fluid. CONSTITUTION:An outer pipe 2 is formed by using a material having a small thermal expansion coefficient such as Invar alloy and super Invar alloy. An inner pipe 3 is formed by a material having a large thermal expansion coefficient such as synthetic resin. A discharge pipe having a dual-tube structure is constituted by the two pipes. Even though the ambient temperature and the temperature of a liquid 4 are decreased, the nozzle is expanded to the inside by the amount of the volume expansion of the inner pipe 3, and the cross section of a nozzle hole 1 becomes small. Even though the viscosity of the liquid 4 is lowered as the result of the increase in temperature, discharge resistance is increased due to the decrease in the diameter of the nozzle hole 1. Therefore, the low viscosity and the discharge resistance are offset, and the amount of the discharge is hardly changed. A constant pressure is applied to the liquid 4 by a piston 6, and the constant quantity discharge can be performed.

Title: Device for detecting erroneous arrangement of container
Inventor: ONO TSUKANE
IPC: B65B1/30
Filed: 1988-03-03
Abstract: PURPOSE:To make it possible to positively detect an erroneous arrangement by the minimum numbers of detecting means by identifying different identification plates located in either a vertical or a lateral row in such a way as to optically detect the erroneous arrangement based on the difference caused by the combination of the transparent and light covering sections of the plates. CONSTITUTION:The combination of the transparent and light covering sections of identification plates Cij and Rij must be one of patterns having two redundancies. When either of the identification plates is therefore optically inserted, the transparent sections more than one are covered by all means. Since each of the vertical and lateral identification plates Cij and Rij takes exclusively either of bit patterns of the vertical and lateral directions, when an error is committed in either of the vertical and lateral directions against an arrangement determined in advance, the error is detected at once. The error in the arrangement of one container out of 80 each=8X10 each can therefore be detected by only 55 sets of identification sensors. As a result, the erroneous arrangement of one tablet container is prevented, safety for automatic separate wrapping can thereby be considerably enhanced.

Title: Rolling method and apparatus for preventing bend of rolled material
Inventor: HIRAISHI YUUICHI
IPC: B21B37/30
Filed: 1979-04-24
Abstract: PURPOSE: To eliminate the factor for generating the bend of the sheet material, by detecting the rolling load under the rolling work, by operating the difference of roll gaps depending on the difference of mill stiffnesses of the drive side and the work side, and by adjusting the roll gap of either one side.  
     CONSTITUTION: The coefficients of the mill stiffnesses of the drive side DS and the work side WS of the rolling mill are previously measured. The rolling load under the rolling work is detected by the load cells 3W, 3S, and the outputs are input to the adder 12, whose output is then input to the roll gap difference correcting signal operator 27 through the switch 26; the operator 27 continously produces the roll gap difference signal depending on difference of mill stiffnesses of both sides DS, WS. Furthermore, the adder 28 is installed in the feedback loop of the detector 10W of the roll gap control system 14W for the side WS, for the purpose of adding  the roll gap difference correcting signal to the output of the detector 10. Hereby, the  roll gap difference is always corrected, and the generation of the camber and the  trouble in feeding the sheet is prevented.

Title: Power source interruption detecting circuit
Inventor: SASAKI YASUTAKA
IPC: G01R19/165
Filed: 1988-03-05
Abstract: PURPOSE:To detect an input AC power source interruption instantaneously, by generating a binary code according to an address of a ROM to match a phase of the input AC power source with a zero potential detector while an input is converted into digital from analog to be collated in comparison. CONSTITUTION:An address counter 16 is reset by a zero potential detection pulse 105 and a frequency 106 sufficiently higher than an AC input power source 101 is counted to send an address 107 to a ROM 13, which outputs an ideal voltage value 103 by a binary code according to the address. For example, the ideal voltage value is scattered into 16 stages of + or -V0-+ or -V7 to indicate a voltage absolute value by 3 bits and a polarity by 1 bit, by 4 bits in total. An A/D converter 11 indicates an input voltage value by 4 bits likewise. These values are compared with a comparator 102 and the results 104 are sent to an alarm detector 14 to generate an alarm 18. A delay to the transmission of the alarm from the interruption of an input is confined to a value equivalent to time for re-timing for the results 104 of the comparison with an FF within the detector 14, that is, about 1 bit of a clock 106 at the most.

Filed: 1987-03-04
Abstract: PURPOSE:To improve the reliability of the titled device by constituting the device so that a write is permitted if the off-set state of a data track and that of a reference track are the same, but the write is prohibited in case said state differ from each other. CONSTITUTION:In the event of a read error, a disk controller controls a head to offset its preceding action in the forward or reverse direction to execute a read action again. If either an offset forward F/F 101 or an offset reverse F/F 102 is set, its output undergoes an OR gate 103, an AND gate 104, and an OR gate 105 to come to be a write-protest signal 106, and prohibits a data- write. Thereafter, if the controller executes the offsetting again in order to recover a read error, the offset-state and the state of a reference track at a time of reading are compared with each other by a comparator circuit 110; in case they coincide with each other, a data-write is enabled with the offset being maintained.
