Title: Quantization circuit for picture information reader
Inventor: KARIYA SANEFUMI
IPC: G06T1/00
Filed: 1986-11-18
Abstract: PURPOSE:To obtain a correct binary signal corresponding to an analog picture signal with a simple circuit, by providing a circuit which removes a shading component consisting of a resistor, a capacitor, and an inductance in a quantization circuit. CONSTITUTION:In the quantization circuit which reads a bar code, the frequency of the shading component included in the analog picture signal is a lower frequency compared with that of a picture information component. Also, a high- pass filter consisting of the resistor, the capacitor, and the inductance has a steep operating characteristic in the neighborhood of a cut-off frequency Fc. Therefore, by setting the frequency Fc at a frequency between the frequency of the shading component and that of the picture information component, shading can be removed. In other words, by passing the analog picture signal inputted to an input terminal 11 through a circuit 16 consisting of the resistor 13, the capacitor 14, and an inductance coil 16, the shading can be removed. In such way, it is possible to obtain a stable binary signal with the simple circuit.

Inventor: KIN TOJIN
IPC: H04W8/26
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To quickly connect a terminal unit to a base station, while significantly reducing the interference due to a pilot channel by multiplexing together an in-phase channel pilot code and an orthogonal channel pilot code. SOLUTION: A base station 11 functions as a center device for cells, i.e., a radio network to provide a radio channel to a terminal unit 10 and also to provide various communication channels including a traffic channel, etc., in addition to a pilot channel that is connected to a control unit 12 of the station 11 through wire. The pilot channel provides a pilot codes which construct the radio channel. Then two different sequences are multiplexed together in an in-phase/orthogonal phase mode and used as a single pilot channel. The cells are divided into groups as in-phase pilot channels, and the cells included in each group are divided as orthogonal pilot channels. Thus, the unit 10 acquires the station 11 via a cell, that uses the same frequency as that which is allocated a code to each cell.

Filed: 1984-12-28
Abstract: PURPOSE:To achieve the sharp rise of sound pressure at a low band frequency, to eliminate the deflection in a high sound pressure level and to attain excellent responsiveness with respect to a sound input signal by constituting a plain shaped diaphragm using a conifer such as cythocus puluse. CONSTITUTION:The conductive speed (v) of sound is generally given by a Young's modulus E and specific gravity (rho) as v=(E/rho)<1/2>. Since the cythocus puluse material has a large Young's modulus for its specific gravity, said material has sound conduction speed as large as about 5,392m/s, and an excellent acoustic characteristic can be obtained. Further, the internal friction of said material is about 6.35Q<-1>X10<3>, which is small compared with that of other trees having similar specific gravity, thereby making it best suited material as the diaphragm of a speaker. The diaphragm 9 is formed into a rectangular shape by one piece of a plate 13, and support members 10 at a back face intersect with grain 14, and further intersect with each other along their diagonal lines at their central parts. Said members are then stuck to the end face of a coil spool 7. When a sound electric current signal flows into a movable coil 3, the movable coil 3 and the coil spool 7 vibrate in response to it. Accordingly, the diaphragm 9 vibrates through the support members 10, and the sound is generated from a front face.

IPC: G03B27/72
Filed: 1984-12-28
Abstract: PURPOSE:To obtain prints of clear pictures even from an insufficiently exposed colored negative film, by providing a filter which extracts only each spectral component of blue, green, and red out of the optical spectrum of white light between a white-light source and optical mixing box. CONSTITUTION:A filter 8 is provided between a white-light source 1 and optical mixing box 3 and the filter 8 has a filter characteristic shown by the solid line in the figure. That is to say, the filter 8 is formed in the same way as well-known color stripe filters or color mosaic filters which separate white light into three colors of red (R), green (G), and blue (B). Of the white light spectrum radiated from the white-light source 1, only light of wavelengths having efficient spectral transmissivity of a negative film 4 become lighting light. Therefore, even to an insufficiently exposed negative film, the color filter action provided by the negative film can be exerted sufficiently and clear printed pictures can be obtained without obtaining so called 'sleepy photographs'.

Inventor: TAKANO YASUHARU
IPC: H01F27/26
Filed: 1988-10-31
Abstract: PURPOSE:To control noise by forming a recessed part at a mounting plate for mounting a magnetic core part opposing to a butt part of the magnetic core where a closed magnetic path is formed by butting a plurality of magnetic core surfaces. CONSTITUTION:A mounting plate 5 is provided with a recessed part 11 with a mounting hole 10 for mounting to a chassis, etc., at both-edge part. This recessed part 11 is deeper than a recessed part 6 and the rear surface at the recessed part 11 side protrudes from the rear surface part of the recessed part 6. Also, a bent part 12 is formed at the both-edge part of the mounting plate 5 and magnetic cores 2 and 3 are joined in one piece by engaging this bent part 12 to an engaging recessed part 13 of a magnetic core 2. During use, magnetic flux within a closed magnetic path leaks from the butt part of the magnetic cores 2 and 3 within the closed magnetic circuit. Thus, a recessed part 7 is formed against this butt part 6 and air gap exists between the butt part 6 and the mounting plate 5. As a result, leakage magnetic flux from the butt part 6 to the mounting plate 5 is reduced and absorption force for the chassis of the mounting plate 5 is reduced, thus controlling noise.

CONSTITUTION:A first layer 10 composed of a first substance, for example, a Si nitride film, is formed on a semiconductor substrate 1. Slits 10a are formed in the first layer in specified positions. A thin second layer 11 composed of a second substance, for example, polycrystalline Si, is formed, and then removed to leave the second layer only on the side walls of the first layer as side walls 11a. A thin third layer composed of the first substance is formed on the entire surface, and then removed to form side walls 10b of the third substance only on the side walls of the second layer 11. All the layers 11a, 11b of the second substance are selectively removed to leave the layers 10, 10b of the first substance. Then the surface of the substrate is etched using the layers of the first substances as a mask to form fine trenches 14, and the layers of the first substance are removed. Thus the reduction of effective channel length and width is prevented and further the microminiaturization of a semiconductor device is achieved.
