Title: Communication method using electric vector potential and communication system
Inventor: YAMASHITA OSAMU
IPC: H04B1/06
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To perform backup for communication in a place where radio wave failure occurs by connecting a radio channel that uses electric vector potential on a propagating medium to a cable or a radio channel to perform communication. SOLUTION: For instance, there is a radio wave failure generation area or a place where a cable circuit is difficult to be installed between a relay base station 1 and a terminal 2. The station 1 is provided with a two-way radio channel 3 that uses electromagnetic waves (light included) and a cable circuit 4 such as telephone with the outside that includes other base stations. Also, it is provided with a two-way radio channel 5 that uses electric vector potential with the terminal 2. Because the electric vector potential has only interaction that changes the phase of a particle (e.g. electron) which has a magnetic dipole, the interaction is extremely weak and is not shielded by conductive material, etc. Therefore, it is suitable for communication inside and outside a radio wave dark room.

IPC: G11B7/26
Filed: 1989-09-29
Abstract: PURPOSE:To measure thickness at an arbitrary position without damaging the surface of a stamper by providing a means to detect a change in the thickness of the stamper, which is moved in the upper part of a holding means while keeping a fixed distance and held by the holding means, as the change of electrostatic capacity. CONSTITUTION:In a state that a stamper 1 is adhered by a turn table 12, this turn table 12 is rotated. When an electrostatic capacity sensor 13 is moved on a swing arm 14, an output corresponding to the thickness of the stamper 1 is outputted from the sensor 13. Accordingly, by converting the output at the position of the electrostatic capacity sensor 13 to a displacement amount, the thickness of the stamper 1 can be easily measured without damaging the surface. The sensor 13 can be moved in the radial direction of the stamper 1 to be rotated. Thus, all the area of the stamper 1 can be measured without fail and by moving the sensor 13 to the arbitrary position, the arbitrary desired position can be freely measured.

The main electrodes 1 are shifted again, and a discharge gap is shaped either of the discharge gap surfaces not used. Accordingly, the main electrodes 1 are moved and used successively until the gap surfaces are removed in the gap surfaces not consumed.

Abstract: PURPOSE:To easily make a signal waveform visible by supplying a video signal for showing an AC signal waveform by one field portion at least at every two vertical scan periods. CONSTITUTION:An oscillating signal outputted from a vertical oscillating circuit 25 is waveform-shaped 31 and becomes a rectangular pulse A. This pulse A is frequency-divided to 1/2 by FFs 32, 33, respectively, becomes pulses B, C, the pulses B, C are supplied to an AND circuit 34, respectively, and AND of the pulses B, C is taken. Therefore, an on-pulse whose period is four vertical scan periods, and also whose pulse width is equal to one vertical scan period is obtained from an output end of the circuit 34. A video pulse E which is outputted from a monostable multivibrator 15 only in a generating period of this pulse D is supplied to a buffer 19 through an AND circuit 35. That is to say, when the pulse E is generated, in one vertical scan period in which the pulse D is generated, a video pulse F of one field portion is outputted to the buffer 19 from the circuit 35, therefore, an audio signal waveform is displayed on a picture of a CRT21, and in the next three vertical scan periods, a display operation of an audio signal waveform is not executed.

Filed: 1990-09-27
Abstract: PURPOSE:To enable the location of a material and the operational state at that time to be judged easily by mounting two or more different coloring light emitting diodes on the indicating part. CONSTITUTION:An indicating part 21 integrally cooperating with a screw 14 radiates in green color when the screw is at a waiting state, and during the screw is in a charging process and the screw is in a primary injection process, it radiates in red color, and as the screw is in a dwelling process, it radiates in yellow color. Accordingly, the operator can ascertain at a glance positively whether the screw is in a completely stopped state or in a dwelling process state. Furthermore, for example, when an abnormal state occurs in the primary injection and thus the screw 14 stops in the primary injection stroke region, a microcomputer 30 recognizes this state and allow the red LED of the indicating part to be glimmering-denoted that is in a abnormally stopped state. Besides, even in indicating parts 23, 25 reciprocating on scales 24,26 integrally with a movable die plate 7 and an eject material 10, a denoting actuation is conducted that is approximately similar to the denoting form in the indicating part 21 integrally moving with the screw 14.

Abstract: PROBLEM TO BE SOLVED: To improve the recording density by constituting an information recording layer and respective layers, excluding a desired resin film for protecting laminated films, of inorganic matter, maintaining a solid state at the incidence of information reproducing light into the respective layers of the laminated films and making the reflectivity of the laminated films higher with an increase in the intensity of incident light. SOLUTION: Information is previously recorded by phase pits on a substrate 81 consisting of polycarbonate. A reflection addition film 86 (Ge-N film) is formed on the substrate 81 and a substrate protective film 82 is formed thereon. Next, an inorganic super-high resolution 83 (Co3O4 film) is laminated thereon. Further, a heat holding film 84 is formed and a reflection 85 is formed thereon. The Co3O4 film is changed in the complex refractive index in the region where the temperature is elevated by the irradiation with a light spot and the reflectivity of this region is increased as a result of multiple reflection and only the recording marks of the high-reflection region are reproduced. The increase in the reflectivity when the complex refractive index of the Co3O4 film changes by the reflection addition film 86 (Ge-N film) is embodied.

Title: Decorative sheet
Inventor: IKEMOTO SEISHI
IPC: E04F13/00
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To stick a decorative sheet to a wall face or the like with ease and in a short time even when an inexperienced person uses the sheet by forming the decorative sheet of a first pressure-sensitive adhesive layer, a reticular base material, a second pressure-sensitive adhesive layer and a mold release paper in that order and forming the second pressure- sensitive adhesive layer in the netted part of the reticular base material. SOLUTION: When a mold release paper 60 is peeled, a second pressure-sensitive adhesive layer 50 located at a position corresponding to the netted part 41 of a reticular base material 40 is moved to the netted part 41 side of the reticular base material 40. The second pressure- sensitive adhesive layer 50 located at a position corresponding to the netted part 42 of the reticular base material 40 is moved to the mold release paper 60 side. When the decorative sheet 1 is correctly positioned during bonding the decorative sheet 1 to an adherend such as a wall face or a ceiling face, the second pressure-sensitive adhesive layer 50 moved to the netted part 41 side of the reticular base material 40 strongly presses the decorative sheet 1 from a pattern layer 20 side. Consequently, a first pressure-sensitive adhesive layer 30 is pushed out to the adherend side such as the wall face or the ceiling face from the reticular part 42 of the reticular base material 40 and is firmly stuck to the adherend such as the wall face or the ceiling face. Thus it is possible to make the reapplication of the decorative sheet 1 to the wall face or the ceiling face at a correct position.
