Title: Pattern matching method
Inventor: TSUKAMOTO MITSUHAYA
IPC: G06T7/00
Filed: 1990-08-09
Abstract: PURPOSE:To shorten calculation time by terminating this calculation on the way when exceeding the accumulation value of the other matching area already calculated and shifting to the collation of the next matching area. CONSTITUTION:Pattern matching is successively performed on respective matching areas M1 to Mm while scanning the matching area M. However, when the calculation accumulation value R exceeds the accumulation value R of the other matching area M already calculated during calculating the accumulation value R of the luminance difference of the matching area M, a truncation signal is transmitted to an address generation circuit 17 from a comparator 12, and this calculation is terminated at the point to be shifted to the collation calculation of the next matching area M. Thus, the needless calculation is unnecessitated, the calculation time is shortened, and the matching speed is speeded up.

Title: Detecting device of biased abrasion of wheel
Inventor: SHIRATORI HIROTOSHI
IPC: G01B21/30
Filed: 1987-08-28
Abstract: PURPOSE:To enable the automatic detection of biased abrasion of a wheel, by providing a vibration accelerometer in a part linked directly to the axle of a vehicle through a bearing element. CONSTITUTION:A vibration accelerometer 3 generates a pulse voltage 3a in an amplitude proportional to acceleration due to vibrations of a wheel 1, e.g. a pulse voltage corresponding to the vibrations of the wheel 1 generated at a joint of rails. A tachometer generator 4 generates a pulse voltage 4a in the number proportional to the number of revolutions of an axle 1 and, hence, to the speed of a vehicle. A control unit 5 compares a vibration generation period and a wheel revolution period led from the voltages 3a and 4a respectively, with each other, and it determines an abrasion as biased when the two periods coincide with each other and when the acceleration due to vibrations is larger than a value set beforehand and calculates the amount of the biased abrasion from the acceleration due to vibrations and the number of revolutions of the wheel at that time. Accordingly, the biased abrasion can be detected automatically and immediately at the same time when the biased abrasion of the wheel occurs, the thus an operation for maintenance is simplified in a large degree.

Title: Alignment of wafer
Inventor: TANAKA HIROYUKI
IPC: H01L21/027
Filed: 1989-08-19
Abstract: PURPOSE:To execute a more accurate correction by a method wherein alignment marks formed on a wafer face are expressed by using coordinates (a radius from the center of a wafer; an angle) and an expansion and contraction amount of the wafer is corrected in terms of the angle. CONSTITUTION:Out of many chips on a wafer face, chips C1...C4 having a radius value (r) of a comparatively equal distance from the central point R of a wafer are selected; coordinates (x1, y1)...(x4, y4) of their alignment marks are measured actually. Their positions are compared respectively with coordinates (x1i, y1i)...(x4i, y4i) of prescribed positions of alignment marks according to a design; a coordinate system of the latter, i.e., a linear arrangement lattice, is corrected by using a method of least squares in such a way that a difference between both is reduced to a minimum. This value is, so to speak, an average value of this correction. Then, regarding a dislocation portion which cannot be removed by the linear arrangement lattice, an expansion and contraction amount in a direction of (r) is computed for each angle theta of the measured chips and is added to the correction amount. An exposure operation of all the chips is executed by using this final correction value.

IPC: B65D90/48
Filed: 1988-08-26
Abstract: PURPOSE:To prevent the corrosion of a tank, by obliquely forming the under surface of the top plate of a tank main body toward an auxiliary tank and providing a lower water level control device and an upper water level control device in the auxiliary tank and providing a plurality of through-holes injecting water by water pressure to the main water feed pipe in the auxiliary tank. CONSTITUTION:Since a main water feed pipe 7, an auxiliary water feed pipe 10, a main normal water level valve 8 and an auxiliary normal water level valve 11 are provided to a small-sized auxiliary tank 3 in a conc. state, they come close to each other, and maintenance and inspection become easy. Since the main water feed pipe 7 is immersed in the water stored in a tank main body 1, the stored water rises through said main water feed pipe 7 by a siphon phenomenon but, since a plurality of through-holes 7a are provided to the bent part of the main water feed pipe 7 in the auxiliary tank 7, the rising water is discharged from said through-holes 7a. Since the emitting parts of the auxilia ry water feed pipe 10 and bypass pipe 9 have a structure not sunk under the surface of the water, no back flow is generated therein. Since the under surface of a top plate 2 is inclined toward the auxiliary tank 3, air is discharged to the outside from an air vent pipe 5 through the auxiliary tank 3.

Title: Orifice trap device
Inventor: OOISHI SHIZUMARO
IPC: F16T1/00
Filed: 1990-08-09
Abstract: PURPOSE:To eliminate foreign matters from an orifice through the suction force of an ejector member by forming a branch passage in a drain inflow pipe, communicating the ejector member with a valve means and providing an orifice communication passage through which the inlet side of the orifice in an orifice trap communicates with a suction room in the ejector member. CONSTITUTION:When a valve means 6 is open, drain or steam inflowing from a drain inflow pipe 1 is free from flowing down to a branch passage 2, passes through a filter 13 to an orifice trap 4 and is discharged from an orifice 8 to the outside. If any foreign matters foul in the orifice 8, they flow down from the cylinder inside of the filter 13 through an ejector 5 to the valve means 6 by opening the valve means 6. By passing a great amount of drain or steam through the ejector member 5 at a high velocity, suction force is exerted on the inlet 9 side of the orifice 8 to suck foreign matters fouling in the orifice 8 to the ejector member 5 for discharge.

Title: Semiconductor integrated circuit
Inventor: NAKAHARA ATSUSHI
IPC: H03K5/02
Filed: 1989-08-18
Abstract: PURPOSE:To output a waveform with less harmonic component causing noise production by adding a transistor(TR) whose gate receives logical '0' or logical '1' to an output side of a pre-stage buffer circuit so as to suppress the amplitude of the output waveform at an output terminal. CONSTITUTION:A rectangular pulse signal R is inputted to a pre-stage inverter 1 to output a rectangular wave having an amplitude between a VDD '1' level and a GND '0'. Then an output waveform of the inverter l is inputted to a source of a TR 3 whose gate is fixed to a VDD '1' level. Then an output waveform of the TR 3 is a rectangular waveform having an amplitude between an GND '0' level and a (VDD-VTHN) '1' level being the subtraction of a threshold level (VTHN) from the level VDD and the waveform is transferred externally from an output terminal. Thus, harmonic components caused by the leading of the edge of the waveform or trailing are suppressed to reduce noise production.

Title: Battery backup circuit
Inventor: SAKAI MASANAO
IPC: H02J9/06
Filed: 1989-08-19
Abstract: PURPOSE:To improve reliability by driving a switching circuit on condition that the control circuit for a switching circuit received both switch close detection signal and voltage drop detection signal. CONSTITUTION:A power switch 2 is a double throw switch, where switch 2A opens or closes a main power source 1 for a load 4. A switch open/close monitoring circuit 5 is connected in parallel with a battery 7 through a switch 2B, and a switch close detection signal is fed to the P3 input of a control circuit 10 when the power switch 2 is closed. Upon receipt of a voltage drop detection signal from a source voltage monitoring circuit 6 under that condition, the control circuit 10 provides a drive signal to a switching circuit 8. Since the switch close detection signal extincts upon opening of the power switch 2, although the voltage drop detection signal is produced, the control circuit 10 does not provides driving signal and the switching circuit 8 is disabled.
