Title: Method for measuring slack displacement of rock ground
Inventor: FUKUSHIMA SHINJI
IPC: E02D29/045
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To measure a slight slack displacement produced at a surrounding rock ground by boring accurately. SOLUTION: Water W in a water tank 8 is filled into a pressurization fluid sealing space S within a pressure sleeve 4 inserted into a measurement hole 2 of a rock ground G, cocks 10 and 11 are blocked, and water surface in the water tank 8 is pressurized by air pressure controlled from a pressurization source 13, thus setting an initial pressure to the water W in a pressurization fluid sealing space S and blocking a cock 9.  After that, when a slack displacement occurs in the rock ground G due to the progress of the boring construction of, for example, a tunnel, the hole diameter of the measurement hole 2 slightly increases and the pressure sleeve 4 expands in radius direction owing to inner pressure, and an inner pressure at the pressurization fluid sealing space S decreases, thus obtaining a slack displacement distortion ε from the pressure change measured by a pressure measuring instrument 12.

Title: Magnetic recording medium
Inventor: UMEBAYASHI NOBUHIRO
IPC: G11B5/82
Filed: 1990-03-06
Abstract: PURPOSE:To reduce power consumption for driving and to stabilize traveling of a recording medium comprising a base film and a magnetic layer holding a lubricant in itself by forming the recording layer so that its magnetic layer has rather gentle rugged base surface with a long center wavelength and providing such ares having rugged slave surface with short wavelength. CONSTITUTION:The surface of the magnetic layer has a surface of gentle rugged base surface with the center wavelength lambda1, for example, as long as >=50mum, on which lots of rugged slave surfaces are provided the center wavelength lambda2, for example, as short as about 30 mum. The torque of a motor loaded on starting is determined by the maximum static frictional force between a recording medium and a head, and thereby, it depends on the surface condition of the recording medium. especially since the medium contains a lubricant to maintain durability against contact with the head, the maximum static frictional force against the head largely varies according to tackiness of the lubricant. Moreover, by reducing the degree of surface roughness of the medium without causing deterioration of the electromagnetic conversion characteristics, torques loaded on the driving motor on starting can be reduced. Thereby, power consumption can be reduced and traveling of the medium can be stabilized.

Title: Liquid level detector
Inventor: SOYAMA MANABU
IPC: G01F23/62
Filed: 1990-03-07
Abstract: PURPOSE:To secure stable slidability and to enable accurate position detection by providing projection parts whose overall area of parts close to an opposite tube is <=1/2 as large as the surface area of the tube on the inside of a float at >=2 places. CONSTITUTION:On the float 9 which incorporates a magnet, the projection parts whose overall area of parts close to the tube 8 is <=1/2 and which have about >=0.5mm height are provided at >=2 places. The float 9 moves while following up the level of oil in a state wherein the level of the oil becomes stable after an engine is started. When the oil level is decreased below a reference value, the magnet 12 in the float 9 responds to the reed SW 7 in the tube 8 to make the contact and a lamp load 4 illuminates to warn a driver. At this time, the rattling of the float 9 in a radial direction is suppressed by the projection parts 10 to obtain an invariably stable working value, thereby securely warning the driver. Further, the oil passes through a recessed part 11, so the periphery of a slide part is wetted with the oil to secure the slidability. Consequently, the need for a material for securing the slidability is eliminated and the cost is reduced.

Title: Single-phase linear motor
Inventor: KORENAGA NOBUSHIGE
IPC: H02K33/16
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To reduce the apparent inductances of accelerating/decelerating coils in operation by a method wherein short-circuit coils are provided at positions where interactions between a movable magnet and the accelerating/decelerating coils do not exist. SOLUTION: Short-circuit coils (copper blocks) 40 are provided on both the ends further than the ends of accelerating/decelerating coils on both the sides. While a magnet 16, i.e., a stage 12, is at an acceleration start position, an accelerating current is applied to an acceleration driver to start the acceleration of the magnet 16, i.e., the stage 12. As currents are induced in the short circuit coils (copper blocks) 40 provided on both the ends, counter electromotive forces caused by inductances are hardly generated. At a deceleration start position, a decelerating current is applied to a deceleration driver to start the deceleration of the stage 12. As currents are also induced in the copper blocks 40 provided on both the ends, counter electromotive forces caused by inductances are hardly generated.  By providing the short-circuit coils at the positions where the interactions between the movable magnet and the accelerating/decelerating coils do not exist, the apparent inductances of accelerating/decelerating coils in operation cart be reduced.

IPC: B62J11/00
Filed: 1988-03-07
Abstract: PURPOSE:To prevent increase of the width of vehicle even if the battery capacity increases by arranging a shock absorber while shifting laterally to the side of an air-cleaner. CONSTITUTION:A shock absorber 13 is arranged between an air-cleaner 9 arranged at one lateral side and a battery 10 arranged at the other side of an air-cleaner 9, where an rear arm 6 and a body frame 2 are coupled through the shock absorber 13. When the shock absorber 13 is shifted to the side of the air-cleaner 9, the shock absorber 13 can be arranged farther inward when the outer dimension thereof increases as the capacity increases thus preventing increase of the width of vehicle. Although the apparent installation space is limited through shifting of the shock absorber 13, the air-cleaner 9 has high profile freedom and can take shape conformable to the remaining installation space, and thereby necessary volume can be ensured easily. Consequently, increase of the width of vehicle can be prevented with the capacity of the battery 10 and the air-cleaner 9 being increased.
