Title: Torsional vibration damper for power transmission shaft in transmission for vehicle
Inventor: NAKAYAMA HIROSHI
IPC: F16H57/02
Filed: 1983-03-17
Abstract: PURPOSE:To aim at improvements in a vibration damping function without receiving any restriction from the constituent parts of a transmission, by constituting a torsion vibration damper so as to bring its damping force into full play in a way of sliding a sliding shaft being inserted into a power transmission shaft, according to its transmission torque, and operating a hydraulic damper being set up outside a gear case. CONSTITUTION:Force of a spring 50 of a hydraulic damper 27 makes a sliding shaft 17 operate its pushing force against a hollow part 5a via levers 30 and 29 or the like, through a piston rod 33 and yet pushes a cam member 20 to the side of a tubular shaft 11 with a pressure receiving member 24. In consequence, cams 21 and 22 keep their innermost engagedness. Under this condition, when transmission torque ranging from the tubular shaft 11 to the cam member 20 suddenly goes up beyond the specified value, the shaft 11 and the cam member 20 rotate in a relative manner, making these cams 21 and 22 slide with each other and causing the cam member 20 to produce its right- hand thrust. This thrust is transmitted to the hydraulic damper 27 via the sliding shaft 17, the lever 20 and so on and absorbed for damping. With this constitution, vibration damping performance can be improved without any restriction from the constituent parts of a transmission.

Title: Train controlling communication device
Inventor: SUGAWARA ATSUSHI
IPC: H04J13/16
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To improve the safety by forming a train controlling signal transmitted from a transmitting means of superposition of two waves diffused by a PN code having a phase difference corresponding to train control, and assigning a larger phase difference to a higher-level speed information signal of train control. SOLUTION: A prescribed standard PN code (PNi) assigned to a block section T from a PN code generating circuit (herein after referred to as PNG) is supplied to a pair of diffusion circuits 3a, 3b, and a PN code (PNi(1')) having a phase difference from PNi is supplied to the other diffusion circuit 3b. The phase difference 1 corresponds to ATC information, and a larger phase difference is assigned to a higher-level speed information signal of train control. Thus, even when phase detecting circuits 21, 121 erroneously confirm a noise as ATC information, this ATC information has a phase difference smaller than the natural ATC information, the aspect output is lower in level than that of the natural ATC information, so that the safety can be ensured.

Title: Semiconductor nonvolatile memory unit
Inventor: HAGIWARA TAKAKATSU
IPC: G11C17/00
Filed: 1979-04-16
Abstract: PURPOSE:To obtain a high-density, high-speed and long-memory-holding time memory unit by driving cells, obtained by connecting the MNOS element of a Poly- Si gate electrode to a switching MIS element in series, connected in a matrix. CONSTITUTION:Memory elements, obtained by connecting memory MNOS element 31 of Poly-Si gate electrode 27 with N<+> diffused layers 22-24 formed in p-type Si substrate 21 by ion-implantation, etc., to switching MIS element 35 in series, are connected in a matrix to form writable and erasable ROM, so that word line 32 will be P0ly-Si. Therefore, the conductance of each cell lowers to shorten the time of signal delay and there is no need to employ offset constitution for element 31; and load capacity on the decoder side decreases to reduce the matrix occupation area, thereby obtaining high-speed and high-density ROM.

Title: Lenticular plate type stereoscopic device
Inventor: NISHIYAMA MASAHARU
IPC: G02B27/22
Filed: 1981-03-30
Abstract: PURPOSE:To visually observe an invariably accurate three-dimensional image in a different direction by placing at least one end part of picture elements within a range grasped by one-directional stereoscopy in a gap state. CONSTITUTION:Pieces of luminous flux of three kinds of images projected on a double renticular sheet DLS strike a projection-side lenticular sheet LS1 at a certain angle and then imaged temporarily on a diffuse transmission film S in the middle of the DLS, and the image is projected in some direction by an observation-side lenticular sheet LS2. Through the operation of the DLS, images on projection type CRTs 5-7 are projected in the specific direction of an observation side, and an observer observes the image (a) of the CRT5 with one eye and the image (b) on the CRT6 to see a stereoscopic image. On the CRT7, on the other hand, no image is displayed, and a difference between the width of a no-image part e' and an interval between both the eyes of the observer is made much less to prevent the observer from viewing an inverted three-dimensional image when simulaneously seeing the minor lobes of an image (c) and the image (a).
