Title: Semiconductor memory device
Inventor: UCHIDA MAKIO
IPC: G11C11/409
Filed: 1987-07-14
Abstract: PURPOSE:To perform swapping at the same address at high speed, by dividing operating timings in one cycle of a two-port RAM having a read-only port and a write-only port so that they are not superposed in a readout and a write operations, and shifting the operations from each other. CONSTITUTION:To realize a two-port function, a read side address buffer R-AB to which read addresses AR0-ARn are inputted is provided separately from a write side address buffer W-AB to which write addresses AR0-ARn are inputted. Internal address signals corresponding to those address signals are supplied to decoders R-DEC and W-DEC, and a word line WRi provided at a memory cell MC is connected to the decoder R-DEC, and also, a word line WWi to the decoder W-DEC, respectively. Thus, by changing the selection level of the word lines WRi and WWi when the read address and the write address are same and selecting the word line connected to a different memory row when they are different, a noise on a power source can be suppressed.

Filed: 1987-07-15
Abstract: PURPOSE:To prevent a collet chuck from chips for stabilizing chucking performance by providing a cutting liquid nozzle in the tip of a draw bar having a center bore for opening and closing a collet bushing to fill a gap in a collet chuck with cutting liquid. CONSTITUTION:When a collet chuck is attached to a precision lathe provided with a loading robot to clamp a workpiece W for cutting, cutting liquid is discharged from a jet 16a in the front surface of a nozzle 16 to the cutting surface during cutting, while cutting liquid supplied from a path hole 16b fills a gap in the collet chuck to block chips from intrusion. When cutting is completed and the workpiece W is removed, the cutting liquid flows from the front end of collet bushing 10 through the gap in the collet chuck to discharge chips attache to the collet chuck while preventing the collet chuck from the intrusion of dust. Next, the clamped workpiece bears against the end faces of a hole in the collet bushing 10 and a snap metal 11, and the cutting liquid fills the gap in the chuck to block the chuck from the intrusion of chips.

Title: Manufacture of bamboo fiber
Inventor: AKIYAMA NOBUTO
IPC: B27L11/08
Filed: 1992-07-03
Abstract: PURPOSE:To make it possible to obtain pellicle-free bamboo fibers by a method wherein coarse crushed material, which is prepared by coarsely crushing bamboo to the direction of growth with a rolling device, is fiberized with a hammer mill type crusher and pellicle parts mixed in obtained bamboo fibers are separated. CONSTITUTION:Cut bamboo, from which blades are removed, is coarsely crushed by being passed through a rolling device. The coarsely crushed bamboo is fiberized with a hammer mill type crusher. The pellicle parts inside bamboo mixed in the obtained bamboo fibers are separated. The mechanical separating method is to scatter bamboo fibers, which are fed from a chute 3 through a feed conveyer 4 to a pair of feed rolls 5, through a large number of triangular teeth provided on a rotary drum 2 onto a conveyer 7. Since the conveyer 7 is arranged only to the neighborhood of the center of the rotary drum 2, the pellicle parts mainly fall on this side of the conveyer 7, resulting in collecting the pellicle parts with blades 6 in a pellicle collecting tank 8. Further, as the separating method by immersing in water, the pellicle part floats when the obtained bamboo fibers are immersed in water, resulting in allowing to easily separate the pellicle part from the bamboo fiber.

Abstract: PURPOSE:To restart communication while switching a telephone line to a telephone set side automatically and to avoid mis-operation by interrupting the facsimile reception if the telephone set is not hooked on within a prescribed time after the reception is started by a switching command signal so as to switch the telephone line to the telephone set. CONSTITUTION:A facsimile equipment FAX uses a telephone set TL and a telephone line TL in common and the switching of the telephone line TL is implemented by the facsimile equipment FAX and the command operation is applied by the telephone set TL. When a switching command signal detection means detects the on-hook of the telephone set at the incoming state of the facsimile equipment, the telephone line is switched to the position of the facsimile equipment to start the facsimile reception. If the telephone set is not hooked on within a prescribed time after the reception is started, the facsimile reception is interrupted to switch the telephone line to the telephone set. Thus, the telephone line is switched to the position of the telephone set automatically to restart the communication thereby avoiding misoperation.
