Title: Optical driving type switch
Inventor: UKO KATSUYUKI
IPC: H04L12/931
Filed: 1987-10-22
Abstract: PURPOSE:To execute switching of an optical information signal of a wide band by providing an optical demultiplexer for allowing a part of an optical control signal of desired wavelength determined in advance to branch and a non-linear reflection type optical switch for bringing an optical signal to switching to a desired output side optical path. CONSTITUTION:If a routing pulse of wavelength lambdai exists in a packet which has been inputted from #1 or #2, it is fetched through an optical demultiplexer 41 for lambdai, amplified by an optical amplifier 42 for lambdai, returned to its original signal line 45 by an optical coupler 43 and irradiates a non-linear reflector 40. In this case, since the pulse of lambdai is amplified to the sufficient light intensity, the non-linear reflector 40 becomes a total reflection state, and subsequently, the signal in the packet which is delivered is all outputted to #3. As soon as the packet is all reflected to #3, the pulse of lambda1 is also ended, therefore, the non-linear reflector 40 is recovered automatically to its original passing state. On the other hand, in case the lambdai pulse does not exist in the packet, nothing occurs in the non-linear reflector 40, and the packet all passes through to #4. In such a way, the switching operation can be executed in accordance with whether the lambdai pulse exists or not.

Title: Measuring method of thickness and distance by using ultrasonic wave
Inventor: NISHIWAKI NOBUHIKO
IPC: G01B17/02
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To enable measuring the time difference of reflected waves when the waveforms reflected from the surface and the back of an object to be measured overlap with each other, by separating a surface reflected wave and a back reflected wave, and measuring a specified layer thickness, from the time difference obtained by the surface reflected wave and the back reflected wave. SOLUTION: When an ultrasonic wave pulse reflection method is used, the waveform of an ultrasonic wave can be expressed by a time function F(t). When an object to be measured is irradiated with ultrasonic wave, the wave which propagates inside the object and returns passing the surface can be expressed by B×F(t+Δτ) which is a little delayed in time as compared with the waveform A×F(t) of the wave reflected from the surface of the object. A, B are coefficients, (t) is time, Δτ, is the delay time generated by round trip in the object, and F(t) snows the waveform of true ultrasonic wave. An observed waveform G(t) of the ultrasonic wave returning from the object is given by C(t)=A×F(t)+B×F(t+Δτ). The coefficients A, B and the delay time Δτ are obtained by using a simplex method.

Abstract: PURPOSE:To provide a winding roll which is prevented from the occurrence of a trouble, e.g. winding wrinkle, winding displacement, and produces uniform winding hardness, by a method wherein a nip pressure is controlled by means of a primary arm and a secondary arm. CONSTITUTION:A pressure force by means of which a spool 11 is pressed against a reel drum 12 according to the swirl lowering angle of a primary arm 18 is controlled. A total nip pressure of the dead weight of the spool 11 and a nip pressure by the primary arm 18 is regulated.

Subsequently, through control of the pressure force of the secondary arm according to the winding size of a winding roll 17, an arbitrary nip pressure is applied on a web 16. This constitution provides a winding roll which is prevented from the occurrence of a trouble, e.g. winding wrinkle, winding displacement, and provides uniform winding hardness.

Filed: 1992-10-06
Abstract: PURPOSE:To prevent bending of a silicon substrate, by using a first polycrystal silicon film as the stopper of etching instead of a silicon nitride film. CONSTITUTION:A polycrystal silicon film is etched until the surface of a silicon oxide film 10 of the part covered only with the polycrystal silicon film is exposed to the outside. Thereby, the top surface of a BPSG film 14 is exposed to the outside, and polycrystal silicon films 13, 15, 17 are changed into polycrystal silicon films 13a, 15a, 17a respectively. Subsequently, by anisotropic etching, the BPSG film 14 and silicon oxide films 18, 16 are removed completely. Thereby, a cylinder-type node electrode comprising the polycrystal silicon films 13a, 15a, 17a is formed. As a stopper of etching, a polycrystal silicon film 9 is used instead of a silicon nitride film. Therefore, the bending of a substrate and the cracks in the peripheral part of a node contact hole 11, which are caused by the presence of the silicon nitride film, can be prevented.

Title: Input/output port
Inventor: ISHII TAKATOSHI
IPC: G06F13/14
Filed: 1985-11-27
Abstract: PURPOSE:To assign practically optionally an inherent I/O port to a suer by forming a user area, a user No. register, a user No. corresponding value setting means, a comparator, and a use allowing means. CONSTITUTION:When user No. '00001001' is written in the user No. register 34, an I/O address is set up to 40HEX, '0' is outputted from a NAND circuit 33, ID data '00001001' is written in the user No. register 34 and compared with '11110110' obtained from the storing means 35 by the comparator 36. Since a coincidence signal is outputted from the comparator 36 in said case, the user area can be used, and because a discrimination gate 37 is enabled, the complement '11110110' of the user No. is outputted from the storing means 35 to a data bus through the gate 37. Consequently, an I/O port inherent in the user can be practically optionally assigned.

Title: Effect device
Inventor: INOUE TOSHIHIRO
IPC: G10H1/00
Filed: 1988-10-25
Abstract: PURPOSE:To remove a click noise by gradually switching a delay length in a comparatively small unit from the delay length before the change to the delay length after the change when the delay length is to be changed. CONSTITUTION:Even when the change of the delay length in a digital memory 12 as a variable delay means is instructed, offset data to set the delay length after the change are never directly inputted to a computing element 31. Namely, the offset data are inputted to the computing element 31 after the offset data are processed so as to gradually change from the offset data to set the delay length before the change through a comparator 32 and an offset data counter 30. Consequently, even when the phase of a delay output signal corresponding to the delay length before the change does not coincide with the phase of another delay output signal corresponding to the delay length after the change, the read address of the digital memory 12 gradually changes from an address corresponding to the delay length before the change to another address corresponding to the delay length after the change, and the phase changes smoothly. Thus, the click noise can be removed.

Abstract: PURPOSE:To realize excellent cycle lifetime characteristic and increase energy per unit volume by satisfying a specific condition when true specific gravity of a carbon material to be a negative electrode active material is measured by a liquid soaking replacement method or gas replacement method. CONSTITUTION:A carbon material having weight of X is soaked into n-butanol filled into a container, and a displaced volume is measured. X/y1 expresses true specific gravity rhoq in a liquid soaking replacement method, wherein y1 represents the displaced volume. A carbon material having weight of X is left in the container filled with helium gas, and volume of displaced helium is represented by yg. A ratio X/yg expresses true specific gravity rhoHe in a gas replacement method. The carbon material is used, which satisfies a condition of rhop<rhoHe-<0.96 wherein rhop represents true specific gravity measured by the liquid soaking replacement method and rhoHe, true specific gravity measured by the gas replacement method. Consequently, a capacity per unit volume can be increased so as to miniaturize a battery.

Abstract: PURPOSE:To accurately survey the communication between nodes by taking packets transmitted on a network into a trap means and displaying information related to sources and destinations of traffic and information related to the intensity of traffic. CONSTITUTION:An address trap machine programmed with addresses of nodes on the network acquires source and destination addresses of each information packet transmitted on a transmission medium of the network without interrupting packet transmission and outputs a 16-bit word including node numbers corresponding to source and destination addresses of the packet.

High level software accumulates values of the array during continuation of the interval of a user-selected measuring time and quantizes each counted value based on set quantities of user-selected example. Thus, proper markers are displayed on a grating matrix.
