Title: Tungsten - copper composite powder
Inventor: RIONIDO PII DOOFUMAN
IPC: B22F1/17
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To produce W-Cu composite powder used for producing a W-Cu pseudoalloy having high electric and thermal conductivity by covering copper phases substantially with tungsten phases. SOLUTION: Tungsten-copper composite powder contains individual grains having tungsten phases and copper phases, and the copper phases are substantially covered with the tungsten phases. Furthermore, the above contains individual grains having copper tungstate phases and tungsten trioxide phases, and the tungsten trioxide phases are present mainly on the surface of the individual grains. The tungsten-coated copper composite powder is pressed to form a compact, and this compact is sintered to form a homogeneous W-Cu pseudoalloy. Thus, the W-Cu composite powder used for producing a sinered part having high dimensional regulating degree can be produced.

Title: Backlash correction device and numerical control system
Inventor: SUGIE HIROSHI
IPC: G05B19/404
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To correct a backlash error by reducing the backlash error showing the increasing characteristic down to a fixed level or lower regardless of a relative feeding speed and according to the backlash information. SOLUTION: When the increase/decrease direction of a position command signal is inverted, a motor inversion detection part 8 outputs a step signal of positive or negative value '1'. A backlash gain correction part 9 multiplies the step signal by the coordinate conversion value of the largest backlash error value that is previously measured. A time dependent filter 10 reduces the value of the corrected step signal at a level rate that is accordant with the time elapsed after the increas/decrease direction of the position command signal is inverted and outputs the reduced step signal as a position correction signal (backlash information). A backlash adder 11 adds the position correction signal to the position command signal and outputs a correction position command signal.  Thus, the backlash error increasing at a fixed rate can be reduced down to a fixed level or lower regardless of a relative feeding speed and according to the backlash information.

Inventor: MIZUNO SEIICHIRO
IPC: H04N5/365
Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To attain image pickup with a high S/N by allowing a simple circuit including a charge amplifier to provide an output of a photodetection signal from a horizontal read section after digital processing. SOLUTION: A reset command signal R is set unsignificant to start an integration by an integration circuit 220, a light receiving element 120 is selected to discharge a stored charge and an integration signal integrated by the integration circuit 220 is compared with a reference value at a comparator circuit 230. A capacitance control device 240 reports a capacitance command signal to a variable capacitance section 222 of the integration circuit 220. Thus, a feedback loop of integration circuit 220-comparator circuit 230-capacitance control device 240-integration circuit 220 is formed and when an integration signal is coincident with a reference value finally within a range, the capacitance control device 240 provides an output of a value corresponding to the capacitance command signal and the photo detection signal is sequentially read via a horizontal read section 250.

Title: Interference wave suppression transformer
Inventor: IZUNA TOMOKI
IPC: H01F27/34
Filed: 1989-12-11
Abstract: PURPOSE:To suppress interference caused by a high frequency intruding into an input coil and stabilize the output voltage to the change of the input voltage by equipping a transformer with a magnetic shunt and an output-side resonance capacitor. CONSTITUTION:A magnetic shunt 4, which consists of a laminate of amorphous electromagnetic steel plates, is fit into a gap between an input coil 1 and an output coil 2 so as to connect the central leg 5 and the side yoke feet 6 of a main iron core 3. A resonance capacitor 9 is connected to the output coil 2 in parallel. The main iron core 3 is made of a low-high-frequency-effective- permeability material and the magnetic shunt 4 has small cross-sectional area to the main iron core 3. As a result, effective magnetic flux generated by the high-frequency component of an interference wave is consumed in the main iron core 3 as a core loss and no high-frequency component is induced in the output coil 2. The magnetic flux generated by the high-frequency component flows to the magnetic shunt 4 instead of running through the main iron core 3 and no electromotive force is induced by the interference wave.

Title: Information recording medium locking systems
Inventor: TANAKA HISATO
IPC: G06F3/06
Filed: 1989-12-11
Abstract: PURPOSE:To prevent an information recording medium from being robbed by providing a locking system with a locking means for setting up the information recording medium to be inserted into a main body device in the locked state to the main body device. CONSTITUTION:When the lug part 22 of the locking mechanism 11 stored in the main body device is stored in the notched part 8 of the card 2, the card 2 is locked to the main body device 1. Then a CPU 10 reads out inherent information stored in the card 2 and stores the read contents in a main memory 12. When an external means such as an operator inputs collating information through a keyboard 4, the CPU 10 reads out the inherent number from the main memory 12, compares the inputted collating number with the stored inherent number, and when both numbers coincide with each other, transmits an unlocking signal to the locking mechanism 11. Consequently, the information recording medium 2 can be prevented from being unexpectedly robbed.
Patent JP-H03179481-A (JP)
Title: Fixing device
Inventor: HAYAKAWA MITSUAKI
IPC: G03G15/20
Filed: 1989-12-08
Abstract: PURPOSE:To eliminate a defect in fixation right after printing operation is started by pressing a fixing roller and a pressure roller against each other with a 1st press- contacting force when printing operation is performed or with a 2nd press-contacting force when not, and making the 2nd press-contacting force less than the 1st press- contacting force. CONSTITUTION:When the printing operation is performed, a cam 6 rotates to press up a movable plate 10 which is rotatable around a fixed shaft 9, so a spring 8 extended between the movable plate 10 and a holding member 4 has specific extension and a force which lifting the holding member 4 operates. A spring 7, on the other hand, is extended between a fixed hook part 11 which is added to a frame, etc., and the holding member 4 and a force which lifts the holding member 4 operates as well as the spring 8. When the printing operation is not performed, the spring 8 enters a free state wherein there is no extension as the cam 6 rotates. The spring 7, however, generates the same spring force as that in the printing operation even when the printing operation is not performed irrelevantly to the rotation of the cam 6. Consequently, the fixing roller and pressure roller are held in a light press-contacting state when the printing operation is not performed and stable fixation strength is obtained right after the printing operation is started.

Title: Throw-away tip
Inventor: SHIKADA HIROSHI
IPC: B23B27/22
Filed: 1988-12-19
Abstract: PURPOSE:To finely cut off chips and improve accuracy in working in a throw-away cutting tip by forming a cutting edge of a cutting edge part and finishing cutting edge part to provide notches only on the cutting edge part. CONSTITUTION:When a throw-away tip 1 is fed leftward, the cutting edge part 8A of a cutting edge 2 shares most part of cutting(a) to form a great amount of chips which are finely divided by notches 3A provided on the cutting edge part 8A which leaves relatively large irregularities by the notches 3A. A finishing cutting edge part 7A having slight notches cuts off the irregularities formed by the notches 3A to generate a satisfactory finished surface. Namely the roughness H in the direction of feeding the finishing surface 5 is a theoretical finished one only generated according to the formula, H=f<2>/8R (f is feed of mm/revolution and R a nose radius (mm) of throw-away tip), leaving no trace of the irregularities due to the presence of notches 3A. The requirement for the feed f is determined to be W>f>P.
