Title: Two-sided skin care wipe material and its production
IPC: B32B7/022
Filed: 1992-09-01
Abstract: PURPOSE: To prapare a laminated cloth material suitable for wiping human skin. CONSTITUTION: The objective wipe material is a laminated cloth material having two plies of fibrous material bonded together. Each ply is a nonwoven web having a fiber composition composed of >=50 wt.% thermally fusible plastic fiber to ensure effective lamination. In particular, one of the plies consists of 100 wt.% thermally fusible plastic fibers to enable ultrasonic bonding of the plies at sufficiently high bonding speed. In addition, for the side where an image such as a logo is to be formed, the ratio of the thermoplastic fiber is reduced to prevent the diminishment of the visibility of the image caused by the swelling of cellulosic fiber during the immersion in an aqueous solution. At least some of the surfaces of the thermally fusible plastic fibers of both plies are treated to render the fiber hydrophilic e.g. by coating with a surfactant.  One ply may have relatively coarse fibers and the other ply may have relatively fine fibers.

Title: Pneumatic radial tire
Inventor: KODAMA SUNAO
IPC: B60C9/00
Filed: 1993-09-20
Abstract: PURPOSE:To restrict the diameter growth of a tire at the time of high speed travelling, and to restrict the lowering of adhesiveness of cords, and to reduce the heat generation by arranging organic fiber cords having a coefficient of twisting at a special value or less as a belt reinforcing layer of a pneumatic radial tire within a predetermined range of cord occupation ratio. CONSTITUTION:A cap 5, which is arranged adjacent to a carcass 1 over the nearly whole area of the outside in the radial direction of belt layers 4, 4, and cord reinforcing layers such as layers 5', which are arranged at the only near both ends of the cap 5 and made of various combination organic fiber cords. Coefficient of twisting (Nt) is set at 0.25 or less, and cord occupation ratio at the time of placing cord is set at 65% or less. Coefficient of twisting (Nt) is computed on the basis of a formula. In the formula, T means number of twisting (time/10cm), D means total denier and means specific gravity (g/cm<3>). Elasticity of the organic fiber cord is improved by reducing the coefficient of twisting, and the belt reinforcing layer 5 or 5' restricts the diameter growth of a tire in the radial direction at the time of high speed travelling to improve the stability of operation and high speed durability.

Title: Semiconductor substrate processor
Inventor: KUMAGAI SEIICHI
IPC: H01L21/304
Filed: 1986-10-29
Abstract: PURPOSE:To prevent dust from reattaching to a semiconductor substrate, by setting a diameter of a processing liquid introduction port, which is installed on a one-sided wall of a processing tank, more largely than that of a processing liquid drain port which is installed on the other-sided wall of the tank. CONSTITUTION:A processing liquid supplied through a circulating filtration device 2A is made to flow transversely as a streamline flow due to a rectifying action of an introduction port 4 of a processing tank 1A. Since a cross sectional area of a drain port 5 is formed to be more small than that of the introduction port 4, part of the precessing liquid overflows from the inner wall of the processing tank 1. Dust 7A generated in process of a semiconductor substrate 3A is classed into the following particles, based on differences in properties of the dust: the floating particles are drained by the overflow (a), and the suspending particles are drained from the drain port 5, and the settling particles are dropped from a drain-board 6A on the rear part of the semiconductor substrate 3A and part of them is drained by the overflow (c). Therefore, all the dust 7A generated in process of the semiconductor substrate is removed from the surface of the semiconductor substrate 3A. Hence the dust can be prevented from reattaching to the surface of the semiconductor substrate.

Title: Superconducting cable joint
Inventor: ISOJIMA SHIGEKI
IPC: H01R4/68
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To provide a joint which is well adapted to connecting a multi-core superconducting cable and which can absorb heat contraction associated with cooling by reducing an outer diameter of stranded cores. SOLUTION: This cable joint is provided with a conductor connector 3 which is connected with a conductor of each core and a shielding connector 2 which is connected with a shielding layer of each core and holds the conductor connector 3 therein. The shielding connector 2 is secured on the ground through a heat insulating connector 1 so as not to move with expansion and contraction of a cable. When the cable expands and contacts associated with cooling, tension can be imparted to each core because the joint does not move, and heat contraction is absorbed by reducing an outer diameter of each of the stranded multiple cores. A connecting point of each core does not impinge on another to be damaged.

Title: Ignition device for internal combustion engine
Inventor: YUGAWA HIDEKI
IPC: F02P3/08
Filed: 1994-10-24
Abstract: PURPOSE: To prevent an excessive timing advance of an ignition position in an internal combustion engine in starting. CONSTITUTION: Signals Vsl, Vs2 generated by means of a signal coil 3 individually in the vicinity of the maximum timing advance position and the minimum timing advance position are converted into control pulses Vp1, Vp2 by meas of the first and the second waveform shaping circuits 4, 5, and on the basis of these control pulses Vp1, Vp2, integrating circuits 8, 9 are controlled so as to generate the first integral voltage Vc1, which increases by the predetermined inclination to the minimum timing advance position after a rise from zero to the fixed voltage in the maximum timing advance position, and the second integral voltage Vc2, which increases from each minimum timing advance position to the next timing advance position by the predetermined inclination. When the first integral voltage Vc1 exceeds the second integral voltage Vc2, an ignition signal Vi is generated.  A threshold value level for the first waveform shaping circuit 4 is set to be higher than that for the second waveform shaping circuit 5, so that igniting operation just after starting operation in the maximum timing advance position is prevented.

Abstract: PURPOSE:To reduce the number of parallel processings, and to perform a multiple gradation recording with high accuracy and at high speed without increasing a circuit scale by separating the data transfer of a thermal head from the occurrence of a binary recording data string. CONSTITUTION:The recording area of one line is divided into k-number of areas, and gradation data DLs at each of the k-number of areas are inputted to RAMs 5-1-5-k.

Title: Device and method for detecting abnormality in abnormality monitoring circuit
Inventor: NAKANE FUMIHIKO
IPC: G06F11/00
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To surely detect abnormality in an abnormality monitoring circuit during the operation of an arithmetic processing unit (APU). SOLUTION: An electronic control device is provided with a CPU for inverting the level of an operation signal and outputting the level-inverted signal in each execution of a base routine (S230, S280) and an abnormality monitoring circuit for counting the fall interval of the operation signal as the charge voltage of a capacitor to be gradually discharged and outputting a reset signal to the CPU when the charge voltage is dropped to a regulated value. The CPU inhibits the succeeding level inversion of the operation signal (S240: NO) up to the lapse of prescribed time from the preceding level inversion of the operation signal when a check start condition is set up (S220: YES), and if the charge voltage VC of the capacitor is not included within a reference range (VL to VH) when the inhibition is released (S240: YES), judges the abnormality of the monitoring circuit (S250: NO, S270).  Thereby whether the monitoring circuit can really count longer time or not can be inspected.
