Title: Correction method of measured data in scanning probe microscope
Inventor: OBA MASAHIRO
IPC: G01B21/30
Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To achieve the correction method of a scanning probe microscope for obtaining measured data without distortion by eliminating a distortion constituent without giving change to the shape of the surface of a measured sample. SOLUTION: The measured data of a scanning probe microscope is taken into a computer as height data being arranged in a matrix. Primary differential data along a main scan direction is obtained for the entire data (S1). The primary differential data is obtained, for example, as the difference between adjacent two data along the main scan direction. Then, the histogram of the height distribution of the entire primary differential data is obtained (S2). Successively, the maximum peak position of the histogram is obtained (S3). The position for indicating the maximum peak of the histogram corresponds to a primary inclination along the main scan direction of entire original data. Finally, the maximum peak position p is eliminated from the original data as the primary inclination (S4), thus eliminating the primary inclination along the main scan direction of the entire data.

Title: Manufacture of aluminum alloy clad material
Inventor: OKUBO YOSHIMASA
IPC: B23K20/00
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To obtain an aluminum alloy clad material provided with a sound joint surface and an excellent strength property by holding a clad surface at a specific temperature for a specific time with a high pressure applied to the surface before thermal refining. SOLUTION: In the method in which an aluminum alloy material requiring thermal refining accompanied with a solution heat treatment is clad with another aluminum alloy material having a different composition and refined to produce a clad material, the clad surface is held at 480 deg.C or higher for 30 minutes or longer with a high pressure applied to the surface before the thermal refining. The high pressure load can be applied by a HIP (high temperature hydraulic pressure press) processing or a hot press processing for applying a vertical pressure to the clad surface, for which the former is used appropriately. As a result, diffusion of solute elements progresses through the clad surface, with the gradient of a chemical potential made sufficiently gentle on the clad surface, and with the generation of pores suppressed through a synergetic effect by the high pressure load.

Title: Transient time injection quantity control device for diesel engine
Inventor: KOTANI AKIRA
IPC: F02D41/12
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To improve drivability by heightening responsiveness to acceleration/ deceleration demand of a driver even in the middle of a smoothening process of fuel injection quantity in a diesel engine. SOLUTION: At the time of accelerator opening ACCPE < preceding accelerator opening ACCPFOL-α in the middle of acceleration smoothening control (YES in S200), an acceleration smoothening fuel injection quantity QSMA is switched to a rise of a second acceleration smoothening quantity QSMA2 portion every cycle of processing (S210). That is, a rise of basic fuel injection quantity QBASE is switched to the rise of the second acceleration smoothening quantity QSMA2 portion which is a smaller rise rate than a rise rate up to this time, in response to the speed reducing demand of a driver. Acceleration is therefore dulled immediately in response to the deceleration demand of the driver even in the middle of acceleration smoothening control so as to be able to respond to the deceleration demand of the driver.  Excellent drivability can therefore be attained without making the driver feel a sense of incongruity.

IPC: H04M11/00
Filed: 1995-12-29
Abstract: PROBLEM TO BE SOLVED: To detect accurately a dial pulse signal from a reception signal sent from a telephone line. SOLUTION: A pre-processing section 5 uses a high pass filter to attenuate a 1st format of a reception signal, the absolute value is obtained and the frequency is shifted toward DC, thinned and outputs a low speed sample signal 27. A voice eliminating section 15 obtains a signal 71 after voice elimination. A head digit dial detection section 6 eliminates a mute pulse and an abnormal waveform to obtain a head digit dial 28.
