Title: Magnetic tape guide drum device
Inventor: CHIKASHIGE KIYOSHI
IPC: G11B5/52
Filed: 1983-03-16
Abstract: PURPOSE:To reduce the deformation of a cylindrical part in case of holding a chuck by providing a circumferential groove-shaped stepped part on a root position of a projecting part from the back part in the cylindrical part, and making the chuck having a fitting-in part to the stepped part generate a pressing component of force toward the back part. CONSTITUTION:A circumferential groove-shaped stepped part 8 is provided on a root position of a projecting part from a back part 2b in a cylindrical part 2c. A sectional shape of the stepped part 8 is an inverted trapezoidal shape, and the inside surface becomes a tapered surface 8a having an angle of theta degrees against the outside circumferential surface of the cylindrical part 2c. A three-way chuck 7 has a fitting-in part provided with a tapered part 7a corresponding to the tapered surface 8a, and when the stepped part 8 is held, a pressing component of force P2 in the cylindrical axis direction toward the back part 2b is generated by an action of the tapered surface 8a against its chuck pressure P1. Therefore, as for a total friction area of the three-way chuck 7 to a lower drum 2, in addition to a friction area to the tapered surface 8a by the tapered part 7a, a friction area to the back part 2b by the pressing component of force P2 is generated. Since the friction area increases remarkably, the holding force can be obtained by a small chuck pressure, and a deformation of the cylindrical part 2c is reduced.

Title: Optical disk device
Inventor: OGAMI EIJI
IPC: G11B7/00
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To shorten access time by changing the frequency of a clock for reproduction generated by a clock generating circuit to a low or high frequency at the time of moving an optical head to another zone and demodulating data based on the changed clock for reproduction. SOLUTION: When the seeking of an optical head is completed and the head is made on to tracks of the innermost zone, a CPU outputs a kick pulse enable signal to a kick pulse generating circuit 51. The current of a constan current source 46 is guided to an adder 44 by allowing a changeover switch 49 to be turned on according to a kick pulse. The frequency of a clock signal to be outputted from a VCO 45 is made to be lowered by a frequency equivalent to one % of the frequency every time the kick pulse is outputted. Then, when the phase of the clock to be outputted from the VCO 45 and phase of the binary signal from a binary circuit coincide with each other and a PLL lock detection signal becomes an H level, the kick enable signal becomes an L level. Thus, a reproduced signal is quickly processed by performing a reproducing processing before the revolving speed of a disk is stablized.

Title: Monitoring device for cooling water
Inventor: KOGA TADATAKA
IPC: G01P13/00
Filed: 1981-03-25
Abstract: PURPOSE:To enable monitoring of flow of cooling water, which is brought into a steady state, through prevention of a moving piece from vibrating by a method wherein a moving piece, which moves through the force of water current, is formed in a hollow structure wherein a pore is provided. CONSTITUTION:Cooling water flows in through an inlet 31 of a clear pipe 30 and flows out through an outlet 32. A moving piece 33 is located in the large diameter part of the clear pipe. In case a discharge is enough, the moving piece is positioned at an upper end as shown in a drawing, and in case the discharge is short, it is situated at a lower end. A water current 34 flows through a hollow part 3b of the moving piece 33, and when it passes through a throttle pore 35, it is throttled to produce a force which pushes upward the moving piece 33. A force, which pushes upward the moving piece and is produced when the water current 34 passes through the throttle pore 35, varies with the size of the throttle pore. In order to increase a discharge sensitivity, the pore may be reduced in a diameter, and in order to reduce the discharge sensitivity, the pore, conversely, may be increased in diameter.

Title: Coding method for interlace picture information
Inventor: WATANABE YUTAKA
IPC: H04N19/503
Filed: 1993-02-08
Abstract: PURPOSE:To improve the coding compression efficiency by applying the same duplicate orthogonal transformation to each block unit altogether even in the case of the field mode in the unit of blocks of a field unit or even in the case of the frame mode in the unit of blocks of the frame unit. CONSTITUTION:A frame memory 2 integrates interlace picture signals 1-3 to one frame and a horizontal duplicate orthogonal transformation (LOT) section 4 applies LOT to the signal 3 and outputs LOT transformation coefficients 4. A coding mode discrimination section 5 outputs coded mode information 16 being the discrimination result of the signal 3 and a vertical LOT section 8 applies LOT to the coefficients 4 in the vertical direction and outputs transformation coefficients 10. Furthermore, a vertical DCT section 9 switches the coefficients 4 to coefficients 11 resulting from applying DCT transformation or the coefficients 10 and a variable length coding section 14 outputs coded coefficient information 15 from the quantization coefficients 13 outputted from a quantization processing section 12. Thus, a higher coding compression efficiency is obtained by using the information sets 15, 16.

Title: Magnetic recording and reproducing device
Inventor: TONO TOSHIHIKO
IPC: G11B15/44
Filed: 1988-02-27
Abstract: PURPOSE:To equalize the required time for fast forwarding to the required time for rewinding by making a reduction ratio of a speed reducing means on the side of a supply reel base larger than that on the side of take-up reel. CONSTITUTION:Rotation torque from a capstan motor 23 rotates a main gear 81, so as to rotate an intermediate gear 75 and a T-reel base 26 via a bypass gear 82, an input gear 84, a driven gear 86 and an idle gear 87. When the reel base 26 is rotated at high speed, the gear 84 is slid on a shaft, so that the gear 84 is engaged with the gear 81. On the other hand, in case of the tape driving method of winding a tape around the outer circumferential surface of a cylinder, take-up torque of the reel base is settled as larger at the time of the reverse rotation than at the time of the forward rotation, because a load due to winding the cylinder with a fixed speed tape is received by a pinch roller 64, a capstan 22 and the T-side reel base 26 at the time of the forward rotation, but only by S-reel base 25 at the time of the reverse rotation. That is, the gear diameter of the reel base 26 is set up to be smaller than the gear diameter of the reel base 25 so as to make their reduction ratios different.

IPC: G01B11/00
Filed: 1986-02-27
Abstract: PURPOSE:To make it possible to accurately detect the edge position of transparent matter of every kind, by arranging not only an image camera obliquely so that a light receiving axis is inclined with respect to the plane of the transparent matter but also a light source on the light receiving axis on the opposite side of the transparent matter. CONSTITUTION:An image camera 2 is arranged so as to have an angle alpha of inclination with respect to the plane of transparent matter 1 in the longitudinal direction line in order to catch the image of the transparent matter 1 from an obliquely upward direction and a light source 5 is arranged on the opposite side of the image camera 2. Because the light from the light source 5 is obliquely projected to the transparent matter 1, the reflectivity on the surface thereof becomes large and the quantity of light passing through the transparent matter is reduced and the part containing the edge of the transparent matter can be projected on an image sensor as clear shade. Therefore, the level difference showing the position of the edge can be made large in the image signal from the image sensor 13 regardless of the transparency of the transparent matter 1 and the edge position of the transparent body of many kinds can be detected accurately and stably.
