Title: Surface potential sensor
Inventor: TOYOSHIMA NOBUAKI
IPC: G01R15/24
Filed: 1994-10-27
Abstract: PURPOSE: To provide a surface potential sensor which can detect the surface potential stably irrespective of the time required for measuring the surface potential and prevent the deterioration of an S/N ratio necessary for the measurement. CONSTITUTION: A surface potential sensor 10 measures the surface potential acting on a material 11 having an electrooptic effect by detecting by means of light the change of a refraction index due to an electric field of the material 11. A dielectric reflecting film 12 is provided at a predetermined surface via the material 11 with the electrooptic effect, and an insulating film 16 is set at the other surface opposite to the predetermined surface. Moreover, a transparent conductive film 13 is set on the upper surface of the insulating film 16 formed of a reflection prevention film. Therefore, the movement of carriers between the material with the electrooptic effect and the transparent conductive film is prohibited, thereby eliminating a tendency for the electric field to be neutralized in the material.  At the same time, the reflected probe light is prevented from being reflected in the material. The intensity of light corresponding to the surface potential can be hence measured.

IPC: F16H37/06
Filed: 1993-10-22
Abstract: PURPOSE:To prevent a tape from being damaged by a method wherein, when a stop instruction is issued during a fast-forward operation, a first motor continues driving until the first motor operates a brake by a control circuit. CONSTITUTION:Even when a stop instruction is issued in a fast-forward mode, a capstan-motor control circuit does not issue immediately a stop instruction, and a capstan motor 1 continues driving for a prescribed time. On the other hand, as soon as a stop instruction is issued, a mode motor 20 starts turning, and it moves a main rod 8 via a gear train 2, a main cam gear 21 and a main cam lever 23. When the rod 8 is moved, brake pins 11a, 12a are detached from a cam face 8b on the rod 8, and respective brakes start hitting a take-up reel stand 7 and a feed reel stand 14. Simultaneously with this operation, a regulation lever pin 9a is pressed by a cam face 8a on the rod 8, a regulation lever 9 is turned, and an oscillating gear 5 is separated forcibly from the reel stand 7. After that, the respective brakes are operated, and they act so as to stop the reel stands 7, 14. Then, the motor 1 is stopped by the control circuit.

Title: Refractory spraying execution method
Inventor: SUGIYAMA KAZUYUKI
IPC: F27D1/16
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To improve a spraying construction method, and hence improve adherability and bonding strength and obtain a thicker constructed structure by spraying a spraying material including a specific amount of magnesium oxide where the average particle diameter and a BET specific surface area are specific to a refractory compounding composition. SOLUTION: When the average particle diameter of magnesium oxide used is less than 0.5μm, it is gelled too before it reaches a surface to be sprayed and hence is deteriorated in adhesion property and a thicker work is unlikely to be obtained. When the average particle diameter exceeds 10μm, it is deteriorated in its adhesion property and bonding strength. Manufacture of magnesium oxide with BET specific surface area of 5 to 150m<2> /g is achieved by calcining magnesium hydroxide at a relatively low temperature for example. It is necessary that a ratio of the magnesium oxide having the average particle diameter and the BET specific surface area in a refractory compounding composition of a spraying material falls within a range of 0.1 to 8% by weight.

Title: Digital servo system
Inventor: SOGABE MASATOYO
IPC: G05D3/12
Filed: 1986-11-08
Abstract: PURPOSE:To avoid such a case where a traveling object goes too far beyond its target stop position and has vibrations by setting the prescribed saturated value to the torque command value and quickly approximating this command value to 0 when the output of a speed deviation detecting means is equal to 0. CONSTITUTION:The output E of a speed deviation detecting means 5 is obtained by subtracting the speed feedback outputted from a speed detecting means 4 from the speed command value Vcmd outputted from a speed command generating means 3. When the output E is not equal to 0, the torque command value Tcmd outputted from a torque command generating means 6 increases and then saturated to be set at a fixed level. While the value Tcmd decreases and gets close to 0 when the output E is equal to 0. Then a traveling object stops when the torque value is reduced down to a level equal to the level of the frictional resistance of the object. Thus the traveling object is stopped by the frictional resistance to avoid such a case where the traveling object goes too far beyond its stop position or has vibrations at the points around the stop position.
