Title: Tapping screw
Inventor: SCHULTE HELMUT
IPC: F16B25/04
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To increase supporting force as much as possible by cutting a milling profile from screw thread screw along an axial line, reducing this profile as space from the front end part is increased and preventing several lines of a rear end part from being formed. SOLUTION: A shaft part has a first screw thread 2, an division 3 without screw thread according to circumstances, an operation profile 4 and a wood screw thread 5. A milling profile 7 is cut from screw thread screws along almost total length of axial line of the wood screw thread 5 and is formed as the notch of a circular segment. The profile 7 reaches a tip 6, is reduced as space from the front end part is increased and is not formed on one or a plurality of screw thread screw of the rear end part. Because the profile 7 departs from the tip 6 and instantly screws into the wall of a reserve hole when the tapping screw is screwed, the formation of the excellent screw thread of the corresponding screw thread is attained and large supporting force can be obtained.

Title: Character recognition system
Inventor: TACHIKAWA MICHIYOSHI
IPC: G06K9/68
Filed: 1986-10-28
Abstract: PURPOSE:To increase a recognition speed by interrupting a matching processing relating to the type of a character which cannot be the candidate of an input character at an early time. CONSTITUTION:The distance between respective feature vectors and the feature vector of the dictionary pattern of the type of the character (k) is operated up to a high order Nth dimension by a matching part 24 and from the operated result, the standard deviation of the distance to the high order Nth dimension is obtained in a threshold decision part 28. The standard value is registered in a threshold table part 30 as the decision threshold of the character value (k). In the matching part 24, the matching distance (d) to the high order Nth dimension between the feature vector Fkn of the dictionary pattern of the type of the character (k) and the feature vector Yn of the input character is operated and the distance (d) is compared with the decision threshold Thk of the corresponding type of character (k) registered in the threshold table part 30 and decided. If d>Thk, since the type of the character of the input character may not be the current type of the character (k), the matching processing to the dictionary pattern is interrupted.

Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a striped artifact by utilizing a so-called projection-reproduction method for which no other phase coding inclination is applied than a reading inclination that allows change in direction between one cycle and other cycles after the exciting of nuclear magnetization. SOLUTION: In an MRI apparatus which has coil devices 3, 5 and 7 for generating an inclined magnetic field and an RF coil 11 which is connected to an oscillator 6 or a receiver 9 by a switch 8, a reproducer 13 is connected through an output device 14 to reproduce a distribition of nuclear magnetization in a regenerated fault from an MR signal. In this case, during the sampling of a magnetic resonance signal, a difference in the direction of the inclination of the inclined magnetic fields is changed between cycles so as to become larger as the deflection increases between groups of measured faults related to cycles. A magnetic resonance signal from a measured fault at a slight distance from the regenerated fault is reproduced according to a magnetic resonance signal from a measured fault at a distance further away from the regenerated fault.

Abstract: PURPOSE:To vary the sound volume of an output according to peripheral noise by permitting a noise detection circuit to extract an impulsive noise from a signal that an antenna receives and adjusting the sound volume of the output according to the extracted output. CONSTITUTION:Only the impulsive noise component which is made incident from the antenna 1 and shows up on the output of an intermediate frequency amplifier 5 is extracted through an HPE 18a. After an amplification 18b and a detection 18c, a pulse corresponding to the impulsive noise is taken out.

Integration 19 is made by a pulse waveform, and a DC voltage corresponding to the number of pulses in a given length of time is obtained. The voltage is compared 20 with a prescribed sound volume setting voltage 21, and a control voltage 20 corresponding to the difference is generated. Thanks to this constitution, a receiver which can change the sound volume of a speaker without a complicated means can be obtained.

Title: Image pickup device
Inventor: SHIGETA KAZUYUKI
IPC: H04N5/378
Filed: 1992-09-02
Abstract: PURPOSE:To suppress the degradation on picture quality caused by the difference of the surface level of the signal from a vertical OB part and and the signal from a horizontal OB part to necessary minimum by clamping the vertical OB part by a prescribed field following a no-signal period. CONSTITUTION:A GAIN switch is performed for one-field following two fields of no-signal period and a signal is made GAIN UP (GAIN large) and the GAIN NORMAL (GAIN small) is performed for the remaining field. At that time, a vertical optical black area (OB) clamp pulse is impressed by the field of GAIN UP after a no-signal period. Thus, the lowering of potential DELTAV generated for the no-signal period is corrected within a prescribed period by the vertical OB clamp at the time of GAIN UP and excellent picture quality which does not generate the shading of the first half part of the field can be realized because the vertical OB clamp is not performed in the remaining field of GAIN NORMAL.
