Title: Steel powder for powder metallugy and method for atomizing molten metal by liquid jet
Inventor: NITTA MINORU
IPC: B22F9/08
Filed: 1993-03-02
Abstract: PURPOSE:To obtain the green steel powder for powder metallurgy excellent in compressibility and strength of green compact by allowing the green steel powder as atomized by a liq. to have a specified narrow grain size distribution. CONSTITUTION:An injected molten steel current 7 is supplied to the confluence with a liq. jet from the slit 2 of an injection nozzle tip 1 and atomized to obtain a green steel powder. In the production of the metal powder, the width SN of the slit is controlled to >=0.2mm, and the accuracy of the injection convergence angle alpha is kept within + or -1.0 deg.. A liq. jet is formed without any cavity and break on the horizontal section Pj at an optional position (j) on a confluent axis (a) after the incoming point (f), and the injected molten steel current 7 is atomized in the jet and solidified. Consequently, a green steel powder as atomized is obtained with the ratio of the grain diameter D84.13 of the 84.13% of the integrated undersize to the 50% grain diameter D50 controlled to <=1.80. The steel powder disintegrated by reduction and/or annealing is mixed with 1% of stearic acid and pressed at 5ton/cm<2> to obtain a green compact having >=120kgf/cm<2> strength.

Title: Roller bit
Inventor: NAKANO MANABU
IPC: E21D9/10
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To enable easy change of extra excavation to the outer dia. of machine without requiring the addition or change of parts by making eccentric the position of axis of both axial ends of roller shaft in comparison with the position of rotational axis of cutting roller. SOLUTION: The axial positions p0 , q0 of axial opposed ends 110L, 110R of roller shaft of a cutting roller 9 are made eccentric in the diametrical direction in comparison with the rotational axis r0 of the roller 9. Then, in the opposed ends 110L, 110R having a rectangular cross section, the distance l1 from the rotational axis r0 of the roller 9 to one side in the diametrical direction of the rectangle form is made larger than the distance l2 to the other side. Accordingly, when the opposed ends 110L, 110R of the roller shaft are connected to the cutter, the protruding margin of the roller 9 to the outer circumferential side of cutter can be adjusted by changing the circumferential posititions by rotating the opposed ends. It is thus possible to change extra excavation quantity without change of parts or the like.

Title: Automatic re-calling system
Inventor: TAGUCHI KIKUO
IPC: H04M3/42
Filed: 1991-03-07
Abstract: PURPOSE:To constitute the system so that by repeating automatic re-calling by the number of times set in advance, it is unnecessary to execute the disposition of re-calling after a calling party always confirms a dial tone sent out of a station, and also, since the other party telephone number is sent out to the station after always detecting the dial tone for suggesting a fact that an outgoing is possible, it does not occur that the station side receives erroneously one digit of the head, and accordingly, it does not occur either that redialing is sent out invalidly to the station. CONSTITUTION:A dial tone receiving circuit 7 detects whether a dial tone sent out of a station exists or not, when a trunk line is caught. A central processor 8 scans an outgoing detection output of the dial tone receiving circuit 7 at every prescribed time and measures an interruption time, and discriminates a classification of the dial tone. When the discriminated dial tone is a control sound for suggesting a fact that an outgoing is impossible, re-calling is repeated automatically by the number of times set in advance after a prescribed time elapses.

Title: Defect detection of filament
Inventor: YOSHINARI OSAMU
IPC: G01N21/89
Filed: 1986-02-28
Abstract: PURPOSE:To accurately detect a defect in a filament, by a method wherein a single light source is arranged as opposed to a light receiving unit to form an optical path and a filament runs through a filament path intercepting the optical path to detect changes in balance with a difference generated between outputs of two solar cells. CONSTITUTION:Optical paths between solar cells and a light source serve as paths of a filament 2. For example, when a normal filament passes, the interception level of the optical path is the same between the solar cells (A) and A' and hence, there is no difference in the electromotive force between the solar cells. But when a defect or the like passes through the optical path, there is a difference generated in the electromotive force between the solar cells (A) and (A'). With such an arrangement, an output difference between solar cells as generated when a defect of a filament passes through a crossing area is detected to make a relay circuit respond. In this case, only when an output difference is generated in the either of optical paths in crossing two directions, the relay circuit is made to respond thereby eliminating malfuctioning.

IPC: G03G15/14
Filed: 1980-03-31
Abstract: PURPOSE:To enable copying paper to be stripped surely from a photoreceptor by putting a stripping tape in sliding contact with one end part of a photoreceptor and interposing the same between the photoreceptor and the copying paper. CONSTITUTION:The copying paper (p) which is let off is grasped between a photoreceptor 1 and a transfer roller 2 by leaving one end part, and at the same timing with this, the original image formed on the peripheral wall of the photoreceptor 1 opposes to the copying paper (p). At the same time, necessary voltage is impressed to the transfer roller 2 and the original image of the photoreceptor 1 transfers to the copying paper (p). The end part of the copying paper (p) extruding from the transfer roller 2 makes sliding contact with a stripping tape 6 and is conveyed as it is along the stripping tape 6 along with the revolution of the photoreceptor 1 and the transfer roller 2 whereby it is stripped from the photoreceptor 1. At this time the pulling direction of a tension spring 8 is the same in the conveyance direction of the copying paper (p) and therefore, the transfer paper (p) slips smoothly without rubbing with the stripping tape 6.

Filed: 1994-02-17
Abstract: PURPOSE:To provide a method for controlling the position of sound image by which a listener has a sense as if the sound image were moving in the vertical direction. CONSTITUTION:A measurement signal is emitted to a sound field 1 and a dummy head microphone 6 arranged at a sound filed listening position measures a relative sound pressure level 8 for a critical band of the sound field and a difference between the measured value and data 9 of relative sound pressure level at a prescribed position in the vertical direction of the sound image generated in advance through experiments is obtained. The characteristic of a frequency equalizer 12 is adjusted to cancel the difference and the frequency characteristic of the listening signal 11 emitted to the sound field is corrected by the frequency equalizer. A listener listens to a sound as if the sound image were in existence at the position actually by correcting the relative sound pressure level at the critical region into the relative sound pressure level when the sound image is in existence in the prescribed position in the vertical direction. The listener feels as if he sound image were moving in the vertical direction by changing the correction timewise.

Title: Mark detecting method and system
Inventor: NODA SHUICHI
IPC: H01L21/027
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To enable a highly reliable mark detection by determining the error quantity according to a modulation wave obtained from subtraction of the waveforms detected from a main and auxiliary measures. SOLUTION: A signal accumulator 11 digitizes and accumulates signal waveforms obtained by a mark signal detection system and normalizes the amplitudes while it separately processes main measure signals M and auxiliary measure signals S is parallel (phase 1). An edge detector 12 detects the edge of a main measure pattern to determine the coordinate origin in an electron beam scan range (phase 2). A subtraction computer 13 obtains the difference between the accumulated signals M and S to express the deviation of the main measure, from the auxiliary measure in the form of a modulation of the detected waveform (phase 3). An analyzing computer 14 fixes the coordinate axes of the modulated waveform data to the coordinate origin and computes the absolute value of the deviation to output it as a numerical data (phase 4).  Thus, a highly reliable mark detection free from the influence of the surface condition of the substrate under test is made.
