Title: Piston device for internal combustion engine
Inventor: ICHIKAWA HIROYUKI
IPC: F16J1/02
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To improve the resistance against wear, low friction property, and airtightness and reduce a consumption amount of lubricating oil by forming an outer annular part by fiber reinforced composite resin, forming a compression ring of a piston by baking and graphitizing the fiber reinforced composite resin, and furthermore, forming a cylinder bore face into a mirror face condition. SOLUTION: An outer annular part 2 is formed like a cylinder in which fibers are mainly arranged in the circumferential direction by using polyimide resin which is heat-resistant as a binding agent as matrix by using a filament winding method in which carbon fibers and carbon threads are used. Since a compression ring 3 is exposed to high temperature combustion gas, it must have the resistance against heat. Therefore, carbon fibers are used as a reinforcing material, and thermoplastic resin and thermosetting resin are molded as matrix and baked and carbonized at a high temperature and high pressure in a predetermined atmosphere for use as its material. Surface finish roughness of a cylinder bore face 6 of a cylinder block 8 is formed to be 0.7μRz or more.

Title: Aircraft
Inventor: IWAZAWA YOSHIAKI
IPC: F24F9/00
Filed: 1995-02-06
Abstract: PURPOSE: To divide and partition a space without affecting the feeling and visibility of space of a cabin and movement of persons in emergency escape and boarding and disembarking by providing a film-like injection nozzle injecting fluid from either of side walls and floor in film form and a suction port capable of sucking film-like injection on a position opposite to the film-like injection nozzle. CONSTITUTION: Since a fluid wall 3 blown from a film-like jet nozzle 4 is sucked into a suction port 5 in a floor surface 03 in film form, a space divided by the fluid wall 3 in the machine axial direction and the direction crossed at right angle to that direction becomes independent spaces with respect to fluid because its upper and lower parts are shut off by a ceiling 02 and a floor surface 03. Even if a passenger on a seat 2 in the space smokes, its smoke and smell will not diffuse or flow toward the passengers in an adjacent space but remain in that space only. Then the smoke and smell are sucked into a suction port 5 following the film-like jet, and exhausted to the outside of an aircraft or recirculated after passing through a CO2 eliminator, smoke eliminator, and smell eliminator. Thus any trouble will not be given to those passengers at all who are sitting outside the space.

Title: Magnetic disk device
Inventor: ITAMI SHIN
IPC: G11B21/10
Filed: 1986-01-31
Abstract: PURPOSE:To improve trackability to a reference speed and to position a magnetic head quickly and correctly by giving to an electric tachogenerator a correction signal canceling external force caused by a change in the shape of a flexible printing conductor. CONSTITUTION:The output signal of a position signal generator 2 is inputted to the electric tachogenerator 3 to convert into a speed signal, which is compared with a reference speed signal. A current is supplied to a VCM 7 and a magnetic head 1 is driven. In accordance with the position of the head 1 the shape of the flexible printing conductor 10 changes to vary external force given by the conductor 10. Accordingly the size of the external force corrected by the output of the generator 2 can be estimated. An offset circuit 8 adds a correction signal corresponding to the position signal of the input to the generator 3. Thus trackability to the reference speed can be improved, whereby the head 1 can be positioned quickly and correctly.

Filed: 1986-01-31
Abstract: PURPOSE:To perform the parallel processing at a high speed with an information processor by executing the subsequency instruction to read out an operand out of the same address of a main storage before the operand writing action is through with a storing instruction, in case the preceding storing instruction is kept in an execution mode. CONSTITUTION:A means 8 detects whether or not the 2nd instruction to be written to the relevant address exists among the instructions under execution without giving an arithmetic operation to an operand within a general-purpose register 5 when the 1st instruction requesting to read an operand out of a certain address of a storage means like a main storage, a buffer storage, etc. is decoded. While a means 10 reads an operand out of the register 5 which is designated by the 2nd instruction for reading an operand before the writing operation of an operand is through with the 2nd instruction in case the 2nd instruction is detected. The operand read out by the means 10 is used as the 1st instruction operand. Thus the 1st instruction processing is accelerated.
