Title: Rolling stock running controller
Inventor: UCHIDA RIYOUHEI
IPC: G08G1/16
Filed: 1978-04-25
Abstract: PURPOSE: To permit rolling stocks to be previously prevented from their mutual collision at a meeting point of railroad tracks, by operating a traffic control system which makes a centralized control of running rolling stocks by means of a computer.  
     CONSTITUTION: Rolling stocks 1 are run on compound railroads comprising railway lines A to C which are joined at a meeting point M. The rolling stock 1 is equipped with a rolling stock controller 11 which receives an electric power from a feeder 3 via a current collector 12 and receives information from a central controller 5 through an antenna 13 and a ground antenna 4. The rolling stock controller 11 is simultaneuosly communicated with an information processor 6 through the work of antennas 91 to 93, which are located on a ground corresponding to controlling sections A3 to A5, and an antenna 14 placed at the rolling stock, and information is communicated between these two devices. And section controllers 81 to 83 are situated at the control sections A3 to A5, and information is transferred to the aforegoing information processor 6 via a transmitting line 7. This permits the rolling stocks to be prevented from mutually colliding.

Title: Phase transition type optical recording medium
Inventor: URUSHIYA TANIO
IPC: G11B7/2405
Filed: 1991-03-14
Abstract: PURPOSE:To improve the reliability of the phase transition type optical recording medium by improving the material to be used for protective layers. CONSTITUTION:This optical recording medium has the lower protective layer 2 and upper protective layer 4 consisting of a compsn. composed of TiO2 and SiO2 on both sides of a recording layer 3 which causes reversible phase transition by irradiation with a laser beam. The TiO2 has a high refractive index and the addition of the SiO2 hinders the crystallization of the TiO2. The thermal stabilitys of the lower protective layer 2 and the upper protective layer 4 are, therefore, high and the laser power necessary for recording and erasing of the recording medium is small.

Title: Capacity type converter circuit
Inventor: KIMURA ATSUSHI
IPC: G01D5/24
Filed: 1985-03-13
Abstract: PURPOSE:To reduce the effect of stray capacity and to enhance noise resistance, by providing variable capacitor changing in capacity corresponding to a physical quantity to be detected, an operational amplifier, a comparator and a constant current limit circuit. CONSTITUTION:The output terminal of an operational amplifier G3, wherein one terminal of a variable capacitor C1 is connected to one terminal thereof and constant voltage is applied to the other terminal thereof, is connected to the other terminal of the variable capacitor C1. A comparator G4 having histeresis characteristics is receives the output of the amplifier G3 at the input terminal thereof and a constant current limit circuit CC is connected between the F-point in the output side of the comparator G4 and the D-point in the input side of the amplifier G3. When the level at the F-point in the output side of the comparator G4 is high, a constant current (i) is flowed in the variable capacitor C1. The level at the D-point is apt to rise by this but the output (the level at the E-point) of the amplifier G3 is fallen and the level of the other terminal of the variable capacitor C1 is controlled and the D-point acts so as to coincide with constant voltage Vs. By this method, noise resistance can be enhanced.

Title: Instruction transfer controller
Inventor: SAKAI KENICHI
IPC: G06F17/16
Filed: 1987-03-04
Abstract: PURPOSE:To retrial an instruction with respect to an error by cancelling an instruction with an error taken place or an instruction interrupted on its way based on an identifier added to the instruction. CONSTITUTION:An instruction identifier is added to an operation code/data of an instruction received by a 2nd instruction execution unit 11 by an instruction identifier (ID) generating counter 16 and stored in an instruction storage circuit 17 till the sending of the instruction. If an error signal is sent, an error instruction cancellation circuit 21 uses an instruction identifier to select an instruction corresponding to the signal and the instruction is cancelled. Even if one instruction is missing on its way of transfer, an interruption instruction cancel circuit 22 uses the identifier to cancel the instruction. Thus, in the 2nd instruction execution unit 11, plural instructions with respect to the error are cancelled. Thus, after the end of cancellation, the retrial of instruction is enabled by a 1st instruction execution unit 10.

Filed: 1986-03-06
Abstract: PURPOSE:To shorten a reading time by holding input data having a reading starting address value and a repeating frequency value and providing a register, etc., to hold the input data to designate the destination address of the read data. CONSTITUTION:Input data INLD has the reading starting address A0 of the upper-most layer of social data and a value (repeating frequency) to show what social data the data are, a reading starting address A1 is outputted to a multiplexer 15 and a repeating frequency 2 is outputted to a comparator 18. When an input request signal IRQ comes to be 0, counting is started by a clock CLK. The second memory 16 reads an output signal IN1 of a register 11, namely, the data processing to the reading starting address in the input data. The comparator 18 compares the output of a counter 9 and a repeating frequency value. Until the output of the comparator comes to be 0, the reading contents of the memory come to be the reading address and the action to read the memory one more time is repeated.

Title: Auto-focusing device
Inventor: MAKABE HIDEKAZU
IPC: H04N5/232
Filed: 1985-03-15
Abstract: PURPOSE:To focus an optical system with a high reliability by detecting a position, where two-stage difference signals of the variance of a luminance standard deviation are most symmetrical, as the focus position. CONSTITUTION:A photoelectric converting means like an ITV camera is used for the optical system to obtain the luminance signal of the image of an object, and the luminance standard deviation is obtained from this signal. The luminance standard deviation of an image obtained in each position is obtained while moving the position of the stage of a microscope or the lens of a camera used as the optical system at a certain pitch in steps. The position where two- stage difference signals of the variance of the luminance standard deviation are most symmetrical is detected as the focus position. Since many samples can be photographed automatically, the inspection for quality control or the like is performed very efficiently.

Title: Mold release agent and manufacture of polyurethane foam molded shape using said agent
Inventor: BORUFUGANGU FUITSUSHIYAA
IPC: B29C33/56
Filed: 1985-03-15
Abstract: A release agent is described, which is suitable for the production of polyurethane foam articles in molds. It is an aqueous emulsion or dispersion of per se known release-effective substances as well as optionally conventional additives, having a water content of at least 60% by weight and preferably 85 to 96% by weight, the water being masked through the effect of lyotropic mesomorphism. Masking and immobilizing the water molecules avoids that the water molecules have a prejudicial effect of the polyol/isocyanate reaction, and is preferably achieved by the combined use of release-effective substances and suitable masking aids. As suitable masking aids especially fatty alcohol polyglycol ethers and ethoxylated fatty alcohols are proposed. The polyurethane articles obtained while using the above described release agent fulfil the standard quality requirements without any of the disadvantageous effects on the environment such as occur with conventional release agents.
