Title: Stepless speed change gear device
Inventor: JINUSHI KATSUYA
IPC: F16H29/14
Filed: 1979-10-03
Abstract: PURPOSE: To contrive miniaturization and enable speed change at any time by a method wherein a constant-speed rotation of an input shaft is converted to an intermittent ununiform rotation of an output shaft through a crank mechanism, a swingable link-node unit in which a relative position of the swinging support is adjustable, and a one-way clutch.  
     CONSTITUTION: Input/output shafts 1, 5 are arranged coaxially and a constant- speed rotating motion of the input shaft 1 is taken out as a reciprocating motion to a crank mechanism. This reciprocating motion is further transformed to a circular repeating motion by means of a swinging link-node unit 10 which is disposed by conpling to the crank mechanism, and then, the reciprocating motion is transmitted to the output shaft 5 as the intermittent ununiform rotation through the one-way clutch 15 interposed between a swingable link-node 10a and the output shaft 5.

Title: Synthetic resin composition
Inventor: HORII MITSUMASA
IPC: C08K7/16
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a synthetic resin compsn. which is excellent in humidityconditioning effects by compounding a synthetic resin with an inorg. porous material which has such a micropore distribution curve that a specified proportion of the total micropore vol. is in a specified range around a micropore diameter at the max. peak. SOLUTION: A sodium silicate powder is baked at about 650-750 deg.C to crystallize into δ-Na2 Si2 O5 , which is dispersed in about 2-50 times as much water, stirred for about 1-5hr, and filtered to give a crystalline layered silicate (e.g. kanemite). This layered silicate is dispersed in an aq. soln. of org. cations (e.g. alkyltrimethylammonium cations), and the resultant dispersion is adjusted to a pH of 8-9 at about 30-90 deg.C, stirred for a specified time, and filtered. A solid component separated by the filtration is repeatedly washed with water, dried, and baked in the air at about 600-1,200 deg.C to give a meso-porous material which has such a micropore distribution curve that the micropore diameter at the max peak is 1-10nm and that at least 60vol.% of the total micropore vol. is in the range of the max micropore diameter ±40%.  Then, 100 pts.wt. thermoplastic resin is mixed with about 10-150 pts.wt. above-obtd. meso-porous material, giving a synthetic resin compsn.

Abstract: PURPOSE:To easily confirm position alignment state by performing a specified operation in a setup state. CONSTITUTION:A measuring mode is set when an operator turns on a run switch 8 after the final check of peripheral chips is finished in a setup state. However, when an auxiliary switch 6 is pressed while a setup switch 7 is turned on, a mounting stand 22 returns to a fine alignment position, moves again to a measuring position after the automatic position alignment of position reference in the X, Y direction is finished, and moves correction distances  x,  y. Then the operator presses a start switch 5 and confirms the position alignment between a probe pin array and an electrode pad array. Thus the position alignment in the setup state can easily be confirmed.

Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To allow a system to recover a transfer error even on the occurrence of the transfer error by transferring data to a target device based on a response returned from the target device so as to directly connect a host device and the target device. SOLUTION: An image supply device 101 sets a format and sends a command to a printer 102. The printer 102 returns its response and then a logic channel is open. Then the image device 101 transfers print data in the unit of blocks by the synchronization transaction. Then the image supply device 101 sends a command to the printer 102, and the printer 102 returns a response. In the case that an error status of the response indicates an error, that is, any error takes place in the preceding data block transfer, the image supply device 101 sends the data having been transferred to the printer 102 once more. Then the processing is repetitively executed till the data transfer is normally finished.

Abstract: PURPOSE:To obtain a target wherein the water cooling effect is sufficient and the generation of a crack is less and the sputtering velocity is large by joining a plate of Cu-carbon fiber composite material to the target material used in a thin film formation due to the sputtering or the like. CONSTITUTION:A target jointed with a Cu-C plate wherein cloth obtained by winding carbon fiber in a spiral shape or knitting it in a network shape is solidified with Cu alloy to make a plate is used for the target material used in a thin film formation. As a joining means, the target material and the Cu-C plate are pressurized and press-contacted in high temp. Or a suitable material (e.g. Cu-Mn) is lined on the target material and the target material is press- contacted with the Cu-C plate via it at high temp. In the Cu-C plate, the thermal expansion coefficient can be changed by the regulation of both the fiber direction of C and the amount of Cu and C, and is nearly made equal to that of ceramic and an intermetallic compd. especially in a low side. Also when interposing the above-mentioned lining material, the joining strength is made large and is occasionally larger than the target material itself. Moreover the heat conduction is excellent because the Cu-C plate is a composite material of Cu and C.

Title: Hydrogen-oxygen solid electrolyte fuel cell
Inventor: NAKAMURA OSAMU
IPC: H01M8/10
Filed: 1983-07-13
Abstract: PURPOSE:To obtain a low-cost fuel cell in which a platinum-system catalyst is not used by using Cu2O as a catalyst for the oxidant electrode. CONSTITUTION:Cu2O is used as a catalyst for an oxidant electrode. Cu2O in powdered form is mixed with a conductive element such as flaked graphite or active carbon in a ratio by weight of 1:10-10:1 to make an oxidant electrode. The catalytic activity of Cu2O powder tends to increase with decreased crystallinity. That is to say, it depends on grain diameter, surface area, surface state and similar factors. Among Cu2O powders, one produced by subjecting Cu(CH3COO)2 to hydrazine reduction at room temperature is preferred because it has the greatest catalytic activity.

Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To easily set the communication destination address for identification of the opposite party of communication by selectively reading information based on a selected area and executing communication based on the read information. SOLUTION: An area where a desired communication address is written is selected utilizing a pen 32.

Then the communication is carried out based on the selectively read information. In such a way, the information on a desired area is selected out of the information shown on the device 26 and the communication destination address can be decided based on the selected information for identification of the opposite party of communication. Therefore, a user of a communication device 10 can execute the communication just by selecting the address of the communication destination out of the shown information. Thus, the user can be set free from the complicated operations for execution of the communication.
