Title: Multiplex communication system of sound circuit
Inventor: TAKADA SHINGO
IPC: H04J3/16
Filed: 1984-03-19
Abstract: PURPOSE:To utilize effectively the communication capacity (number of bits that can be transmitted for a second) of a circuit, by transmitting no 1st signal in case no sound signal to be transmitted exists and transmitting only the 2nd signal at a transmission speed higher than that at which the 1st signal is multiplexed and transmitted. CONSTITUTION:A detection part 12 detects the presence or absence of a sound which is supplied through a sound input terminal 1, and this detection result is delivered to a multiplex control part 4 in the form of a sound presence detecting signal 13. When the signal 13 shows the absence of sound, the transmission speed of the 2nd signal is increased (maximum Kbps) and the 2nd signal is not multiplexed to the 1st signal. Then only the 2nd signal is delivered to an input terminal 5 of a transmission line (the 2nd transmission mode). When a demodulating part 11 of the 2nd signal receives a control signal from the part 4, the part 11 demodulates the 2nd signal at a speed of Kbps. Then the part 11 delivers the demodulation output to a demodulation output terminal 10 of the 2nd signal and also a sound demodulation request signal to a demodulation control line 14 of the 2nd signal.

Title: Semiconductor light position detector
Inventor: KONDO MASATAKA
IPC: H01L31/02
Filed: 1988-03-07
Abstract: PURPOSE:To prevent a short-circuit between conductor layers and increase overall translucence by making one of the conductor layers formed on both sides of a semiconductor layer to be composed of a transparent material and allowing the other and the semiconductor layer to have many fine through holes common in the direction of the thickness. CONSTITUTION:A conductor layer 20 on the light incidence side is made of a transparent material. A semi-transparent or opaque semiconductor layer 18 has many fine holes 23. Further, a conductor layer 22 on the side opposite to the light incidence side has many fine through holes 23 common to the hole 23 provided on the semiconductor layer 18. Light passes through these fine through holes and the conductor layer made of a transparent material regardless of the transparency of the material forming the conductor layer on the side opposite to the light incidence side. At this time, since the conductor layer on the side opposite to the light incidence side has the common through holes 23, the section between both conductor layers is not short-circuited.

Title: Apparatus for making fresh water
Inventor: OKADA SHIYUUICHI
IPC: C02F1/469
Filed: 1982-03-31
Abstract: PURPOSE:To easily make low-grade fresh water, by pouring water to be purified into two tanks on both sides among three water tanks formed by providing two permeable partition walls between an anode and a cathode, and attracting ions in the liquid to the vicinities of the electrodes. CONSTITUTION:Raw water is poured into chambers A, C on both sides among three chambers A, B, C divided each other by partition walls 2. DC voltage is then applied between two electrodes 3a and 3b from an external circuit to attract anions such as Cl- and SO4- to the anode 3a and cations such as Ca<2+> and Na<+> to the cathode 3b by electric attraction. As a result, water in the chamber A is converted into an alkaline state abound in anions, water in the chamber C is converted into an acidic state abound in cations, and water in the chamber B is converted into low-grade fresh water having the low concentration of ions. This low-grade fresh water is withdrawn outside, while the water in the chambers A, C are merged together and drained as neutralized water.

Filed: 1986-03-11
Abstract: PURPOSE:To enable accurate detection of mold reducing rate by fitting a dolly bar as changeable toward approaching or alienating direction to a casting slab at nearer side to the casting slab than to a non-contacting type position detector fitted to a reducing mold body block. CONSTITUTION:The position detectors 32, 33, which detect the reducing rate of the casting slab 2 at the side faces of the reducing mold body block 14, 16 and the dolly bars 34, 35 are fitted apart from the detector 32, 33 under the described distance y1. When the dolly bard 34, 35 are brought into contact with the casting slab 2 by decending and ascending of each block 14, 16, the dolly bars 34, 35 are gradually deformed to become to narrow distance y1, and next the distance y2, at the time of contacting the blocks 14, 16 with the casting slab 2, is detected by the detectors 32, 33. After that, even if, the blocks 14, 16 reduces the casting slab 2, the dolly bars 34, 35 are not shifted and the distance y3 becomes gradually shorter and the reducing rate yR=y2-y3 is detected continuously. In this way, the reducing rate of the mold to be casting slab is accurately detected and the service life of the position detector is lengthened.

IPC: G02B27/02
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain a wide visual field angle and high image quality with a small size and lightweight by forming the observation side counter substrate of a liquid crystal display element of an optical fiber bundle and forming an observation side end face to a shape complying with the curvature of field of a magnifying optical means. SOLUTION: The counter substrate is formed of the optical fiber bundle 101 of which the observer side (right side) end face is worked to a shape to negate the curvature of field which occurs at the magnifying optical means. As a result, the distance between pixels and the optical fiber bundle 101 is settable at the extremely short distance of about 10μm meeting the thickness of a liquid crystal layer 105. The luminous flux 107 transmitted through the pixel 106 is made incident on the optical fiber 108 disposed to correspond to the pixel 106. Rays, such as rays 109 transmitted through the pixels exclusive of the pixel 106 arrive at the optical fiber 108 as well but since the incident angle thereof is large, the incidence thereof on the optical fiber is not possible if the NA of the optical fiber is limited.  Namely, the degree of the coexistence of the pixel information is suppressed about 1/14 that of the conventional examples.

Filed: 1992-03-12
Abstract: PURPOSE:To prevent the divergence of a knock judgment level by detecting the standard deviation and cumulative relative frequency in the distribution of approximate logarithmic conversion value on the knock intensity value, and combining these detection results to prepare two kinds of knock judgment levels. CONSTITUTION:The knock of an internal combustion engine is detected by a knock sensor M1. The knock intensity value is detected by a means M2, and the existence of knock is judged by a means M3. Knock control factors such as ignition timing and an air-fuel ratio are controlled by a means M4. The standard deviation and cumulative relative frequency in the distribution of approximate logarithmic conversion value on the knock intensity value are respectively detected by means M5, M6. When the standard deviation is within the allowed range, a knock judgment level is prepared by a first means M7 on the basis of the standard deviation and cumulative relative frequency. When the standard deviation is out of the allowed range, the knock judgment level is prepared by a second means M8 on the basis of the value, obtained by deducting the deviation part from the allowed value, and the cumulative relative frequency.
