Title: Disk eccentricity measuring device
Inventor: NAGANO SHUICHI
IPC: G11B7/095
Filed: 1993-09-28
Abstract: PURPOSE:To measure the eccentricity amount in succession during the reproduction by detecting the peak value and the bottom value of a slide error signal and calculating the eccentricity amount of a disk recording medium from the difference between the peak value and the bottom value. CONSTITUTION:A servo controller 8 inputs a tracking error signal TE and produces a slide error signal through a phase compensator 8a and an LPF 8b, and supplies it to a system control part 12. The control part 12 obtains the peak value P1 and the bottom value P2 of the slide error signal and stores them in a P1 memory 36 and a P2 memory 37. The sine-wave signal component due to the eccentricity appears in the slide error signal but the amplitude changes according to the eccentricity amount. The difference between the peak value P1 and the bottom value P2 corresponds to the eccentricity amount. Thus, the eccentricity amount can be easily measured during the operation.

IPC: G06F19/00
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus, for the simulation of the acceleration of a flying object, in which a test scale is small and in which the costs of the simulation are small. SOLUTION: In a simulation method, a moving object 3 which is accelerated is rushed into a decelerating tube 1 which has a gas spouting hole 2 at the tip, it is decelerated while a as inside the tube 1 is being compressed, and a deceleration which is equal to the actual launching acceleration of a flying object is generated. That is to say, since the moving body 3 is moved while the gas inside the decelerating tube 1 is being compressed, a deceleration according to the pressure of the compressed gas is generated at the moving body 3. Then, the area of the gas spouting hole (aperture), the initial pressure of the gas filled into the inside or the like is changed. Thereby, the acceleration or the like of the moving body 3 can be controlled at a short distance.

Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To easily comprehend the sense of time remaining, even for the recording of the time limited to be short by displaying the remaining time capable of recording to a set time length corresponding to the change of the residual time, when recording is started. SOLUTION: When a calling voice is recordable, a name set to a selected number is displayed in an upper stage, and a telephone number is displayed in a lower stage. A handset is lifted up first, and calling sound is emitted after the lapse of a prescribed time. Along with that, the lower stage of a display part 150 is filled with the display of the required number of black tiles. After the calling sound is ended, the black tile display is erased from the left to right by one character, and all the characters are erased in required seconds. When voice is uttered to the handset in the required seconds of erasing the black tile display, the voice is recorded and registered as the calling voice. In such a manner, since time lapse is displayed to the display part 150 at the time of recording the calling voice, the residual time capable of recording is recognized.

Title: The other person's response detecting circuit in general telephone network
Inventor: KATSUMATA HIDEKI
IPC: H04M1/00
Filed: 1988-10-20
Abstract: PURPOSE:To obtain the other person's response detecting circuit to reduce the burden on a CPU in the internal part of a terminal equipment by providing a polarity inversion detecting circuit in the output side of a polarity detecting circuit to detect the polarity of a circuit. CONSTITUTION:A polarity inversion detecting circuit 9, which is composed of a filter part and an inversion detecting part, is connected to the output side of a polarity detecting circuit 6. A polarity signal is not directly transmitted to an input port 4 but processed by the external circuit of a CPU1. Then, a polarity inverting signal, which is the result of the processing, is sent to the CPU1. Thus, the load of the CPU1 is reduced. Here, since the polarity signal of the circuit is apt to include a line noise or a self-dial pulse, at first, the range of the signal is limited by the filter part, accuracy is improved and after that, detection processing is executed by the inversion detecting part. Accordingly, the above mentioned processing is omitted from the load of the CPU1.

Title: Metal mask and metal combination screen plate using same
Inventor: TOGO TETSUO
IPC: H05K3/12
Filed: 1990-10-04
Abstract: PURPOSE:To improve the separability of a plate and to apply printing to a minute area with higher density by making the thickness of the resist formed corresponding to the perforations of the metal mask having to be formed to a substrate metal used in an electroforming method substantially same to or more than that of the metal mask. CONSTITUTION:Since the thickness of the resist formed on a substrate metal is made substantially same to or more than that of a metal mask being a product, no overhang is generated. Since the thickness of one layer of a liquid resin is 1-10mum, it is necessary to laminate the resist at the time of solid coating or printing in order to make the thickness of the resist almost same to or more than that of the product. Since the thickness of one layer can be made as thick as 50-100mum in a dry film resist, lamination is unnecessary or, even in the case of lamination, the number of layers at the time of lamination, that is, the number of processes can be reduced and, therefore, the dry film resist is pref. Since the substrate metal is removed by dissolution after electroforming, the bending of the product can be prevented when the product is separated from the substrate metal.

Abstract: PURPOSE:To enhance a stroke, stiffness, stability and positioning accuracy as well by letting the guiding mechanism be made up of a stage which is moved at the first degree of freedom while being in point contact with a V-groove at the fixed side with two carbide balls at distant positions, and also in point contact with a plane at the fixed side with one carbide ball, and of a feed screw moving the aforesaid stage. CONSTITUTION:The guiding mechanism slides over a plane 4 in the definite direction with no carbide ball 1 rotated, which is housed in each cavity of a stage 5, in a state that each carbide ball is in contact with the plane 4 at one point. The aforesaid mechanism also slides in the definite direction with no carbide ball 1 rotated, which is housed in each cavity of the stage 5 over a V-groove 3, in a state that each carbide ball is in contact with the V-groove 3 at two points. Therefore, the mechanism is free from microscopic rattling due to the rotation of each carbide ball 1, and movement in the definite direction can thereby be made with high accuracy by finishing the plane 4 and the two surfaces of the V-groove 3 to the optical flat. In a moving mechanism, a feed nut 8 is moved as a feed screw 6 fixed on the fixed side is rotated, and the stage 5 is moved followed by the aforesaid movement. By this constitution, those such as a large stroke, high stiffness, high stability and high accuracy in positioning can thereby be materialized.
