Title: Die
Inventor: NISHIMURA TSUKASA
IPC: B29C48/31
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To make the spots of a sheet and a film smaller by varying thickness in the width direction while retention-deterioration of fluid being prevented by structure to prevent the generation of a step and a gap in the channel of a die, and make the thickness spots of each layer smaller even in a multilayer die. SOLUTION: In a die for extruding a molten resin continuously in the form of a sheet or a film, a void is formed at least in one lip which forms the channel of the molten resin, it consists of the first thin wall part 1 in which the thickness of a thick wall part from the surface of the channel to the void is 1-4mm, a second thin wall part 2 of 2-6mm thickness which is located downstream from it and slightly thicker than the first thin wall part 1, and a third thin wall part 3 of 0.5-3mm which is located downstream from it. The void side of the second thin wall part 2 is made to be structure in which sufficiently rigid beam-shaped blocks 4 fly out at specified intervals in the die width direction, the gap 8 between the channels can be changed by pushing/pulling the beam-shaped blocks 4.

Title: Variable gauge bogie for rolling stock
Inventor: TAKAO KIKUO
IPC: B61F7/00
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To change a gauge while the rolling stock is running, and concurrently prevent twisting force from being applied to an axle even when the variable gauge bogie is inclined in the right and left direction. SOLUTION: An axle end pivot 32 is fixedly attached to the end part of a rolling stock axle 6, and a spherical bearing 34 is mounted to the axle end pivot 32. A tapered cylinder 35 is fixedly attached to the spherical bearing 34, and a guide pin 40 is inserted into the tapered cylinder 35 in such a way that it can be slid in the axial direction. The guide pin 40 is fixedly attached to an axle box 4 by way of an upper and a lower bracket 36 and 37. Since the axle box 4 can be rotated with respect to the axle 6 by the spherical bearing 34, even when the variable gauge bogie is inclined in the right and left direction, the right and left axle boxes 4 are revolved with respect to the axle 6, and therefore no twisting force will never be applied to the axle 6.

Title: Facsimile equipment
Inventor: ISHIYAMA KOSUKE
IPC: H04N1/387
Filed: 1988-01-31
Abstract: PURPOSE:To reduce the communication time by splitting and recording a received picture of a length in excess of the length of recording paper by a device at the receiver side. CONSTITUTION:Prior to the reception of picture information, a control section 4 controls a transmission/reception section 3 so that the split recording length determined in advance or detected by a recording output section 2 and informed to the control section 4 is sent by a transmitter. Moreover, the picture information received by the transmission/reception section 3 is informed to a recording output section 2 and the control section 4 controls the recording output section 2 and the transmission/reception section 3 so that the recording output section 2 divides the picture information by each split recording length sent to the transmitter before and outputs it to the recording paper. Thus, even in case of communication for the original whose length is longer than the length of recording paper, it is not required to transmit/receive the control signal on the communication between the originals in case of communication and the communication time is reduced.

Title: Manufacture of grooved base plate for optical disk
Inventor: SAKAMOTO YUJI
IPC: B29C43/18
Filed: 1990-02-02
Abstract: PURPOSE:To prevent the occurrence of bubbles by a method in which the diameter of the central hole of a plastic base plate is made smaller than the diameter of the central hole of the complete object of an optical disk, and the relation between the diameter of a boss and the diameter of the central hole of the plastic base plate is prescribed. CONSTITUTION:The diameter of the central hole of a plastic base plate is made smaller than the diameter of the central hole of the complete object of an optical disk, and the relation between the diameter r1 of a boss 8 and the diameter r2 of the central hole of the plastic base plate is kept in r2-5mm<=r1<=r2-0.3. Consequently, when the base plate is placed, the clearance 10 generated between a central boss 8 and the inner peripheral part of the central hole of the base plate, has the size of some degree, therefore since the bubble 9 which remained in the clearance is relatively large, the bubble stays in the central hole, and even when the bubble is generated on the inner peripheral surface of the base plate 4, the bubble is moved to inner peripheral part and stays in the clearance 10 when the resin which has been pressed extends. When the clearance is less than 0.3mm, small bubbles are generated easily as usual, and when it is larger than 5mm, the base plate moves easily when it is pressed, whereby the stamper 1 may receive damage by the contact with the stamper 1 etc.
