Title: Magnetic recording and reproducing device
Inventor: NAGASAWA TAKESHI
IPC: G11B15/43
Filed: 1992-12-28
Abstract: PURPOSE:To diminish variation in tension due to change of a tape winding diameter by holding a magnetic tape between a guide roller and a pressing contact pin which are provided in a tape traveling system under the state of fixing load torque of a supply reel at a constant value. CONSTITUTION:Holding force F for holding the magnetic tape 2a between the guide roller 40 and the pressing contact pin 37 is decided by spring force of a coil spring. Then, the relationship between upstream side tension T1 and downstream side tension T2 to be imparted to the magnetic tape 2a is denoted by equations of T2=T1+alphaF and T1=Tq/R, where alpha is a friction coefft., and Tq is torque working upon a supply reel, while R is a tape winding diameter. Since the torque Tq is constant, the tension T1 is inversely proportional to the change of the tape winding diameter R. alpha F is a constant value irrespective of any change of the tape winding diameter R. Consequently, the holding force between the pressing contact pin 37 and the guide roller 40, making the value of alphaF is set for an appropriate value, so that influence upon T1 due to the change of the tape winding diameter is diminished, and back tension is brought to an approximately constant value.

Abstract: PROBLEM TO BE SOLVED: To provide a pulsation reducing device which can be easily joined by welding and the like, and generates no fear of mixing a trash to a fluid by the joining. SOLUTION: A cylinder body 31 has a blocked end 310 and an opened end 311, while a cylinder body 32 has a blocked end 320 and an opened end 321. When the length of the cylinder body 31 is made L11 , and the length of the cylinder body 32 is made L12 , L12 >L11 . The cylinder body 31 reduces the pulsation of the frequency f11 (f11 =C/4L11 , C is the speed of sound), while the cylinder body 32 reduces the pulsation of the frequency f12 (f12 =C/4L12 ). The cylinder body 31 is joined to a piping 1. And the cylinder body 32 is inserted in the cylinder body 31, until it passes a through hole 3100 opened to the blocked end 310 of the cylinder body 31, and its opened end 321 reaches to the inner surface of the piping 1, and it is joined to the blocked end 310 from the outer side.  Since it is joined from the outer side, the joining is made easily, and no joining trash is generated in the cylinder body.

Title: Image processing system
Inventor: KASHIWATANI ATSUSHI
IPC: G06T7/00
Filed: 1991-12-05
Abstract: PURPOSE:To obtain an image processing method for extracting the high luminance value region on the image such as halation caused on a metal surface or the like. CONSTITUTION:A virtual-data generating means 11 receives image data I (x, y) and generates N (x, y) pieces of virtual data on each picture element point. Thus, two-dimensional data, wherein the higher the luminance value points, the more the data are present, are formed. The data are outputted into a fuzzy clustering means 12. The fuzzy clustering means 12 receives the two-dimensional data outputted from the virtual data generating means 11 and performs fuzzy clustering. The fuzzy clustering means 12 outputs a cluster center (b). The cluster center is converged in the vicinity of the position of the center of gravity in the high-luminance-value region on the image.

Title: Mud discharge tank
Inventor: MORIMOTO TADASHI
IPC: E21D9/06
Filed: 1998-12-09
Abstract: PROBLEM TO BE SOLVED: To smoothly supply charged mud into a suction pipe by installing a spiral conveyor used to stir and convey collected mud water in a tank. SOLUTION: Earth and sand and mud water dropped from a basket of a gravel separation device 1 move to the trough 3f side along an inclined face on a bottom of a mud tank 3 and are deposited sequentially from the inside of the trough 3f. Since a spiral conveyor 3b has a stirring action, it is driven to stir earth and sand and mud water in the mud tank 3 and measure viscosity by a viscometer 3d. When viscosity is high, mud water is supplied through a filler port 3e to adjust to proper viscosity. When mud water is discharged from the mud tank 3, the spiral conveyor 3b is driven to convey earth and sand in the mud tank 3 to the suction port 3a side and discharge it to the outside of a pit by a mud discharge pipe 5 connected to a suction port 3a. Consequently, it is possible to provide the spiral conveyor with two functions of stirring and conveying mud water.

Title: Relative position detecting device
Inventor: KUDO KOICHI
IPC: G01D5/36
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To ensure a wide distance between an optical head part and a matter to be measured by emitting the light passed through a slit having a periodic pattern of a prescribed light transmissivity to a scale having the same periodic pattern, and detecting the intensity of the reflected light or transmitted light caused by the change of the relative positions of the slit and the scale. SOLUTION: A slit 103 divides the light emitted by a collimator lens 102, and a pattern for changing the transmissivity in a fixed period is formed on a scale 104. Since the slit 103 generates a pattern beam of the same period as the period of the transmissivity of scale on the scale 104, the transmission pattern of the same period as the scale 104 is sufficient when it is a perfect parallel light. When the light from a light source 101 is emitted to the scale 104 through the slit 103, the pattern beam of the same pitch as the scale 104 is formed on the scale 104. The pattern beam repeats interruption and transmission by the movement of the scale 104, and its change of light quantity is detected by a light receiving part 105.
