Abstract: A vibration actuator control device includes a control unit and a driving unit. The control unit outputs a first control signal for controlling driving of a first vibration actuator including a first vibrating body and a first contact body, and outputs a second control signal for controlling driving of a second vibration actuator and including a second vibrating body. The driving unit (i) outputs a first alternating-current voltage in a first plurality of phases set based on the first control signal, and (ii) outputs a second alternating-current voltage in a second plurality of phases set based on the second control signal. The control unit individually sets a phase difference of the first alternating-current voltage based on the first control signal and sets a phase difference of the second alternating-current voltage based on the second control signal, and commonly sets a first alternating-current voltage frequency and a second alternating-current voltage frequency.

[Solution] Erythritol granules each containing hydroxypropyl cellulose or hydroxypropyl methylcellulose, said erythritol granules having such a property that, when a sample prepared by adding 1.6 mg of magnesium stearate to 160 mg of the erythritol granules is filled in a mortar having a diameter of 8 mm and then the sample is compressed at a compression rate of 10 mm/min under a pressure of 0 to 100 MPa, the average yield pressure at 30 to 100 MPa is less than 2941 MPa. According to the present invention, it becomes possible to produce erythritol granules which have sufficient bindability while retaining the characteristic properties of erythritol.

Abstract: A strong pressure and a strong shearing force are exerted to a mixture, constituted of two kinds or more of powder materials including a drug powder, while causing the mixture to pass between a press section (26) of a press head (24) and a receiving surface (25) of a cylindrical rotator (23), thereby combining the drug powder with the other powder material. For example, at least one of a drug and a biocompatible polymer is made into a nano particle whose average particle diameter is less than 1000 nm, and the nano particle is made into a composite in accordance with a dry mechanical particle combining method, so as to form a polymer nano composite particle. Thus, it is possible to produce a composite particle, which contains a drug under a stable condition, in a short time, and it is possible to remarkably improve its handling property without losing advantages of the nano particle.

Abstract: A dual hoist derrick system for deep sea drilling, capable of elevating a very long and massive heavy object involved in a drilling for deep sea, is provided with a normal drilling hoisting system and a heavy load hoisting system arranged on a single derrick in parallel. The derrick is mounted on a skid movable in a horizontal direction. The skid is provided with a cut broader than a blow-out prevention device, so that the skid may travel to a position of the blow-out prevention device to lift up the blow-out prevention device. The system contributes to speeding up in hoist speed of offshore drilling units for deep sea, reducing working hours and improvement in safety.

Abstract: A resist pattern (dummy pattern) is formed on the surface of a substrate which pattern has a shape corresponding to a desired connection hole, and thereafter an insulating film such as SOG is formed covering the resist pattern. The insulating film is etched back until the resist pattern is exposed and thereafter the resist pattern is removed by ashing or dissolving. With the above processes, a connection hole corresponding the resist pattern can be obtained. As a layer for forming the dummy pattern, an SiN or polysilicon layer may be used instead of a resist layer. The substrate may have wiring patterns formed thereon via an insulating film or may not have wiring patterns. A fine connection hole having a high aspect ratio can be formed.

Abstract: In a speed change gear device having a gear shaft (30 in FIG. 1), bearings (32A, 32B), and a housing (21) which accommodates the gear shaft and the bearings therein; lubricating auxiliary vessels (50, 60) are mounted within the housing (21) so as to catch oil scooped up from a collection of oil (P) and to introduce the received oil into the bearings (32A, 32B) not directly immersed in the collection of oil (P). The lubricating auxiliary vessels (50, 60) are arranged at positions which lie laterally and lower than the intermeshing portion of gears (38, 39). The level (PL) of the collection of oil (P) is set at a height at which the lower end (H2) of at least one (39) of the gears is immersed in the collection of oil (P). Due to the location of the lubricating auxiliary vessels (50, 60), the bearings (32A, 32B) are suppled with sufficient quantities of oil even during low-speed rotation of the gear (39).

Abstract: A fluid apparatus includes a pneumatic cylinder having a main body, a piston, and a hollow rod. A ball screw shaft engaged with a ball nut fixed to the piston is rotatably and axially unmovably mounted in the cylinder and extends in the hollow rod. A magnetic brake for braking the ball screw shaft is fixed to an end portion of the main body of the cylinder. The number of revolutions of the ball screw shaft is detected and outputted in a signal form by a rotary encoder. A primary solenoid controlled valve reciprocates the piston by connecting a pressure source either to a first or second port of the cyliner, and secondary solenoid controlled valves connect a pressure source either to a first braking pressure port or to a second braking pressure port.
