摘要:
The invention is an immobilization apparatus comprising: a container (1) having a nozzle (4) formed for exhausting a solution; a charging means (PS, 5, 4) for charging the sample solution within the container; and an airflow generating means for generating airflow (Af) crashing into the sample solution. The immobilization apparatus is configured to operate the charging means and the airflow generating means simultaneously, atomize the solution into microparticulate substances charged while maintaining its activity and functionality by the electrostatic force due to the charge of the sample solution charged by the charging means and the crash energy due to the crash of the airflow generated by the airflow generating means into the sample solution, and exhaust it from the exhaust outlet (4), and the charged microparticulate substances are deposited on a substrate (7) by the electrostatic force.

An offline programming device for preparing an operation program for making a robot with a hand perform a handling operation for an object with respect to a machine tool. The device includes a hand-position designating section designating a relative positional relationship between the object and the hand when the hand holds the object; a first calculating section determining a position and orientation of the object mounted on the machine tool when the robot performs the handling operation, based on a command specifying a position of the object and included in a workpiece processing program given to the machine tool; a second calculating section determining a position and orientation of the robot acting to hold the object by the hand when the robot performs the handling operation, based on the relative positional relationship between the object and the hand and the position and orientation of the object; and an operation-program generating section generating the operation program by using the position and orientation of the robot.

This invention provides a method for detection of conformational change of a protein immobilized on a substrate. In concrete, the method comprises, forming a sample film comprising a protein immobilized on a substrate, adding a substance to be detected for its activity to affect to the conformational change of the protein onto the sample film, and detecting the conformational change of the protein. The method enables to measure conformational change of a protein with immobilized state, using minute amount of protein in a short period for a number of samples in a short period all at once, rapidly and simply.

A cast aluminum base frame of a movable guide for a timing chain in an internal combustion engine is produced by a die in which the parting lines are located so that the shoe-engaging surface of the base frame and the pivot shaft-receiving hole are each formed by a continuous surface of the die, without oppositely pitched drafts.

A sprocket has a central through-hole for attachment of the sprocket to a rotating shaft, a boss coaxial with the through-hole, and teeth on the periphery of the sprocket. The boss has a cylindrical outer surface coaxial with the through-hole and having stepped small-diameter portions formed at opposite ends of the boas. A cushion body is in the form of a disk having an eccentric through-hole and includes an annular bearing having a cylindrical inner surface defining the through-hole, and a cushion member press-fitted over a cylindrical outer surface of the bearing. The bearing is slidably mounted on the cylindrical outer surface of the boss on each side of the teeth, and a ring-like flange is press-fitted over each stepped portion of the boss so as to prevent the cushion body from moving in the axial direction of the sprocket while allowing sliding movement of the cushion body relative to the boss. With this arrangement, the cushion body is kept in a prescribed position at all times even when the wrapping angle of a chain relative to the sprocket exceeds 180°. Thus, striking noise at engagement points between the chain and the sprocket can surely be reduced by the cushion body.

A tensioner device for a power transmission chain, which has a small number of components and hence is able to reduce the cost of manufacture and assembly, can be mounted or installed easily, and requires only a small space for installation thereof. The tensioner device consists of a tensioner lever (4) pivoted at one end thereof on a support shaft (3) disposed on a fixed member (2) and carries, on a surface thereof facing a chain (7), a shoe (8) slidably engageable with the chain (7). The opposite end of the tensioner lever (4) has formed therein a plunger receiving hole (9) having an opening (9A) facing in a direction opposite to the surface to which the shoe (8) is attached. A plunger (10) is slidably received in the plunger receiving hole (9) and is held in abutment with a stopper (17) disposed on the fixed member (2). The plunger (10) is urged in a forward direction projecting outwardly from the plunger receiving hole (9), and a unidirectional restriction device resists movement of the plunger (10) in the reverse direction.
摘要:
A novel method is proposed for the preparation of a calcium silicate powder particularly useful as a filter aid in the filtration of an acidic aqueous liquid by virtue of the extremely high acid resistance of the calcium silicate powder. The inventive method comprises a hydrothermal reaction of a blend of a silica-containing material and calcium oxide or hydroxide in a specified molar ratio under specified reaction conditions to form calcium silicate, which is then subjected to a heat treatment at 800.degree.-1200.degree. C. for 0.5-2 hours. An improvement can be obtained in the clarity of the filtrate obtained by the filtration using the calcium silicate powder prepared by the inventive method as a filter aid when the hydrothermal reaction for the preparation thereof is conducted in an aqueous solution of potassium hydroxide in a specified concentration.

An image forming apparatus capable of selectively discharging a sheet having an image formed with toner on one surface thereof and a sheet having images formed with toner on both surfaces thereof includes a fixing unit configured to fix a toner image on a sheet, a sheet stacking portion configured to stack sheets each having the toner image fixed thereon, and a control portion configured to control a maximum sheet stacking amount of sheets stacked in the sheet stacking portion. The control portion controls the maximum sheet stacking amount set when sheets, at least one of which has the toner images formed on both surfaces thereof, are stacked to be smaller than the maximum sheet stacking amount set when sheets each having the toner image formed on one surface thereof are stacked.
