IPC: C08J7/00
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To suppress a neck-in phenomenon without generating deflection of a resin film or irregularity of a thickness by a method wherein after impressing high voltage to a thermoplastic resin film of a molten or semi-molten state, it is laminated on a base material. SOLUTION: A resin film 2 extruded in a molten or semi-molten state from a T-die 1 passes a partial discharge field for which a cooling roll 3 is used as a counter electrode from a discharge electrode 5 connected to a high voltage generating device 4. Thereafter, the resin film 2 comes in contact with the cooling roll 3, and is fixed together with a base material 7 by pressure by being pinched with the cooling roll 3 just thereafter to obtain a laminate 8. A surface of the resin film 2 is charged by impressing high voltage, and pushed onto a pressure roll 6 by electrostatic force. Consequently, the neck-in in is inhibited. Further, the pressure roll 6 can be used as the counter electrode.

Title: Method for controlling speed change gear
Inventor: ASAYAMA YOSHIO
IPC: B60K20/02
Filed: 1986-07-07
Abstract: PURPOSE:To reduce a speed-change-shock, by elevating the clutch pressure of a speed-change-clutch for the next stage when the transmission-input-shaft- revolving-speed becomes equal to the product of the output shaft revolving speed and the gear ratio in the next speed-stage. CONSTITUTION:When the clutch pressure (d) at the time of the 'power-on and shift-down' is gradually lowered, the transmitting torque is decreased, while the vehicle body acceleration (a) is gradually decreased as well. At the same time, the revolving speed (c) of the transmission input shaft starts rising. Next, the difference in the revolving speeds (or relative revolving speed) (b) between the clutch input shaft and the clutch output shaft, which occurs when the clutch for the next stage to which the speed is to be shifted down is connected, is calculated. This difference can be obtained as the difference between the actual input-shaft-revolving-speed and the value converted into an input-shaft-revolving- speed that can be obtained by multiplying the transmission-output-shaft- revolving-speed by the gear ratio in the next speed stage. When this difference becomes nearly zero, the pressure of the speed-change-clutch for the next speed stage is gradually elevated. Accordingly, the torque can be transmitted smoothly, thereby minimizing the speed-change-shock.

Title: Heat exchanging with fins
Inventor: KOMA HACHIRO
IPC: F28F1/32
Filed: 1986-07-07
Abstract: PURPOSE:To prevent a heat transfer fin from bending if part of a heat exchanger is bent, by using a heat transfer fin of which cutouts in slits or in louvers provided on the surface of a fin are opened in parallel with the edge line of a fin, and of which distances of cutouts to the edge line of a fin are determined to be not equal to one another. CONSTITUTION:The distances from cutouts 21a-21d in slits on a heat transfer fin 21 to the edge line of a fin are different from one another such as X11 and X12, or X11' and X12'. Accordingly the bending stress is dispersed to a distance on the line of X11 or X12, and to that on the line of X11' or X12' from the edge line of a heat transfer fin 21 when part of a heat exchanger 22 with fins is bent. With such an arrangement, the heat transfer fin 21 is prevented from being bent during the time of a bending work applied to the heat exchanger with fins, besides air flows are secured on the fin and the quantity of exchanged heat can be secured as well.

Title: Reaction gas supply flow rate controller of fuel cell
Inventor: GOTO HEISHIRO
IPC: H01M8/04
Filed: 1989-06-21
Abstract: PURPOSE:To suitably control of a reaction gas by detecting the measuring error of gas supply amount, time dependent deterioration of a fuel cell, and quality variation of reaction gas, and by correcting them. CONSTITUTION:If increase in reaction gas is smaller compared with increase in output current l, a fuel cell 1 is short in the gas. This concentration drop is detected at times t2, t3 with an analyzer 29, and supply amount correction circuit 21 outputs a correction signal 215 which requests additional gas supply to a flow rate control circuit 28. The flow rate control circuit 28 outputs a corrected flow rate control signal 28S which requests additional gas supply with the correction signal 21 to an electropneumatic positioner 4A to increase the opening of a supply control valve 4. The supply amount of reaction air is increased from the time t2 and that of fuel gas from the time t3 over the reference increase line. As a result, the concentration of oxygen in offgas and that of hydrogen are repeatedly controlled toward the reference concentration.

Filed: 1990-06-18
Abstract: PURPOSE:To prevent dislocation of a sheet material in feeding and to reduce cost of a sheet material feeder by providing an inclining mechanism for inclining a surface on which the sheet material is mounted toward a base surface. CONSTITUTION:A protrusion part 25a is provided at a groove 25 of a feeder 2, and a recess part 11a on a hood part 11 of a cassette, respectively, only on the surface opposite to a surface 'A' to be a base for feeding. Therefore, the base side is guided at a certain height by a motion to take in and out the cassette 1 of the feeder 2, while the opposite side is raised as the hood part of the cassette 1 runs onto the protrusion part 25a. As a result, the cassette 1 takes an attitude that the base side is inclined downward. Moreover, once attaching is finished, the recess part 11a conforms to the protrusion part 25a, and the cassette returns to the horizontal position again. That is, as sheet materials are surely gathered to the base surface once by their own weight, the sheet materials are set at the regular position after attaching of the cassette 1 is finished, and it becomes unnecessary to forcibly apply all the sheet materials to the base surface.

Title: Analysis of sodium dicyanamide
Inventor: GOTO TAKESHI
IPC: G01N30/88
Filed: 1990-06-18
Abstract: PURPOSE:To analyze sodium dicyanamide with a high sensitivity by using an anion column packed with a polyacrylate resin into which a quaternary ammonium group is introduced as a packing material and a moving phase which is prepd. by mixing boric acid, etc. CONSTITUTION:A moving phase tank 3 is communicated via a sample injecting port 2 and a moving phase transfer pump 5 with the inflow side of the anion exchange column 1 of a low exchange capacity packed with the polyacrylate resin into which the quaternary ammonium group is introduced as the packing material. A detector 4, such as a UV absorption photometer or electrical conductivity meter, is connected to the outlet side. This packing material lowers the salt concn. in the moving phase soln. to lower the electrical conductivity of the moving phase itself. The UV absorption of the moving phase itself is eliminated by using the moving phase prepd. by mixing the chemical materials, such as boric acid, mannitol and tris(hydroxymethyl)aminomethane, which have no UV absorption. The electrical conductivity or UV absorption of the dicyanamide ions generated from the sodium dicyanamide by dissociation is detected by suppressing the background by the moving phase to a lower level.
