Patent JP-H025610-A (JP)
Title: Output circuit
Inventor: UENO SHOJI
IPC: H03K19/0175
Filed: 1988-06-24
Abstract: PURPOSE:To prevent occurrence of noise by not operating a MOS transistor, into the gate of which a delay element is inserted, but operating each one of MOS transistor on the pull-up and pull-down sides at a transient changing time when the output level changes. CONSTITUTION:When input signals are switched from an 'H'-level to an 'L'- level, a transistor 14 for shifting level is turned on by means of a control signal from a CMOS inverter circuit 13 and the voltage of a Zener diode 18 drops due to the turning-on current of the transistor 14. Since a resistance is inserted into the gate of a transistor 21, the signal voltage to the gate is delayed and the transistor 21 is not turned on in this transient period. The transistors for pull-up and pull-down are separated into two pieces in such way and the gate signal is delayed at the transient changing time of an output Out. When MOS transistors 19 and 21 on one side are not operated, but only transistors 16 and 17 are operated in such way, occurrence of electromagnetic interference, etc., can be prevented.

Title: Automatic measuring device
Inventor: NISHIOKA MASAKI
IPC: G01B5/016
Filed: 1992-06-16
Abstract: PURPOSE:To obtain the coordinate of a contact point using a sensor attached to a spindle by detecting displacement amount of a probe at the tip of the sensor and then making offsetting by the amount of probe radius in the normal vector direction obtained from that displacement amount. CONSTITUTION:A measuring sensor 1 which has a probe at its tip detects displacement amounts epsilonx, epsilony and epsilonz by making the probe contact with a workpiece. The displacement amounts epsilonx, epsilony and epsilonz detected by the sensor 1 are A/D converted and supplied to both an NC unit 5 and a displacement amount synthesizing part 2. At the synthesizing part 2, the synthesized value of normal vector of surface epsilon=(epsilonx<2>+epsilony<2>+epsilony<2>)<1/22> is obtained based upon the displacement amounts epsilonx, epsilony and epsilonx. Meanwhile, a skip signal generating threshold value setting part 3 is provided for setting an output threshold value epsilon0. A skip signal generating part 4 compares the synthesized value epsilon with the threshold value epsilon0, and outputs skip signal to the NC unit 5 only when epsilon>=epsilon0. The unit 5 calculates the coordinate value of a contact paint using a user macro program of NC.

Besides, the width and the length thereof are set so that the left and right trailing edges of the original 14 set in the sheet 10 are exposed from the notches 15a and 15b. Even when the original is not correctly set in the sheet 10 and it is obliquely set, the trailing edges on both left and right sides of the original can be detected. By relatively discriminating that the backward trailing edge is the trailing edge of the original, the original can be perfectly read without breaking off one part of the trailing edge of the original.

Title: Method for calculating masking threshold for digital audio coding signal
Inventor: JONATHAN ROLANZ
IPC: G10L19/00
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To calculate a masking threshold efficiently. SOLUTION: In the method for calculating a psychological and audible masking threshold for a digital audio coding signal, a casuality infinite impulse response(IIR) filter is used to represent one side of a masking function with two sides that has polygonal line curves whose gradient is S1, S2 and S3, S4, and a non-casuality IIR filter to represent the 2nd side is used. The signal is preferably processed through the non-casuality filter in a reverse time direction to make the filter casual and stable. As a result, both sides of the masking function are represented by the stable filter. Furthermore, the number of calculations using the IIR filters is much smaller than the number of calculations resulted from using one FIR filter or over.

Title: Method for driving image forming device
Inventor: YOKOYAMA TOMOAKI
IPC: G03G15/09
Filed: 1988-06-23
Abstract: PURPOSE:To secure image density by widening the developing page of a downstream developing device and returning the gap to the same value as that of the downstream developing device which is independently driven when a ratio of toner in an upstream developing device to a carrier becomes a reference value or below. CONSTITUTION:Among developing devices 1 and 2 containing developer of the same color, the developing gap Ds2 of the downstream developing device 2 is made wider than a developing gap DN when the downstream developing device 2 is independently driven. The developing devices 1 and 2 are simultaneously driven so that toner is supplied to the same electrostatic latent image in plural developing areas X1 and X2. When the ratio of the toner in the upstream developing device 1 to the carrier becomes the specified reference value or below, the developing gap Ds2 of the downstream developing device 2 is returned to the value DN when the downstream developing device 2 is independently driven. Thus, density reproducibility and thin line reproducibility can be improved and required copy image density can be secured.

Abstract: PURPOSE: To enable mass transfer of the pulverized body whose apparent specific gravity is small by providing a stirring arm at the tip of a screw and also an air nozzle in a large tube part corresponding to the tip of the screw.  
     CONSTITUTION: When the pulverized body is charged in a pulverized body transferring tube 15 from a pulverized body charging port 16 and the screw 18 is rotated by driving a motor 19, the pulverized body is sent out to a conical tube part 15b with the rotation of the screw 18 and further is transferred to a small tube part 15c by the air blown out from the nozzle 21. On this occasion, the air blown out from the nozzle 21 strikes against the pulverized body being transferred through the small tube part 15c and flows backward and thereby the pulverized body stays in the vicinity of the inside wall of the joint part of the large tube part 15a and the conical  tube part 15b, the staying pulverized body is sent back to the front of the nozzle 21 by the stirring arm 22 rotating together with the screw 18.
