Patent JP-S6298192-A (JP)
Title: Heat transfer device
Inventor: YANATORI MICHIO
IPC: F28D15/02
Filed: 1985-10-25
Abstract: PURPOSE:To constantly obtain a desired quantity of heat being transported by detecting the temperature or the internal pressure of a condenser or a tank connected thereto or the both, and increasing or decreasing the input to a heater of an air bubble pump in accordance with the signal thereof. CONSTITUTION:When power is supplied to a heater on the root portion of a rise-up pipe 9, which is located near to a condenser 1, an evaporative liquid 12 existing in the condenser 1 receives heat and boils up. Air bubbles being generated draw up together the liquid 12 existing in the periphery thereof, and run over the top portion of the rise-up pipe 9, descending within a liquid return pipe 8 and reaching an evaporator 4. The liquid 12 receives heat from the outside of the evaporator 4 and evaporates. Vapor being generated reaches the condenser 1 via a vapor rise-up pipe 7 due to a vapor pressure difference. The vapor is cooled in the condenser 1 and discharges condensation heat and drops in the form of a liquid. After falling within a pipe 2 of the condenser 1, the liquid flows into the rise-up pipe 9 and the same cycle of the operations is repeated. A sensor 14 is hermetically attached to a part of the condenser 1, and signals P and T from the sensor 14 are delivered to a control part 13 to vary the quantity of input amount W of the heater 10.

Title: Power source voltage sensing circuit
Inventor: KAWASHIMA HIROMI
IPC: G06F1/26
Filed: 1984-11-13
Abstract: PURPOSE:To flow haraly a DC current by forming a voltage dividing circuit by two sets of transistors controlled by diode acting transistors and an inverter output of a Schmitt trigger circuit. CONSTITUTION:A voltage dividing circuit is formed of an N enhancement type Q1 having connected drain gate and makes diode operation, a power source Vcc controlled by an output of an inverter INV in a Schmitt trigger circuit and having a high trip point at the time of rising of voltage, an N enhancement type Q2 between grounding GND and a P enhancement type Q3. When the power source Vcc rises, a node N2 also follows up the rise of voltage of a node N1, and if a divided voltage exceeds the trip point of the INV, Q6, Q7 of the INV become on, and the potential of a node N2 drops. Then, the Q2 becomes off and the Q3 becomes on, and DC current in Q1-Q3 is cut off. The Potential of the node N1 rises rapidly and the node N2 falls rapidly to the grounding GND level. The same effect applies in the case of falling of the power source Vcc, and a DC current hardly flows. Thus, a circuit suitable for a CMOS semiconductor device is obtained.

Title: Inter-vehicle distance alarm system
Inventor: YAMAUCHI YOSHIKATSU
IPC: G01S13/93
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To realize a highly reliable inter-vehicle distance alarm system, by reducing influences of radio interference and of multi-path. SOLUTION: An actual inter-vehicle distance at a present point of time is computed as a distance an electromagnetic wave propagates in a period of time equating to a time difference between a time signal (in a signal processing part 30) by a clocking means possessed by an own vehicle and a time signal (received by a transreceiver 10) representing the same time and received from another vehicle, and an alarm is sent out when the actual inter-vehicle distance value is smaller than a predetermined safety inter-vehicle distance value. As for the frequency of the electromagnetic wave, a different frequency is allotted to every traffic lane by a frequency control signal produced by receiving and decoding a light signal received by a light receiver 20 and therefore radio interference is avoided.  In order to prevent a time error from being produced between the two vehicles, a time reset signal is received by the light receiver and supplied to the signal processing part 30 and a time counter in the signal processing part 30 is reset with appropriate timing.

Abstract: PURPOSE:To retrieve objectively and at high speed proteins having high degree of similarity by providing a means to extract consecutive elements from a coincidence matrix between a specific amino acid residue included in the array data of the protein and the specific amino acid residue included in an array of the amino acid residues, and performing quantization using a similarity degree calculation means. CONSTITUTION:A coincidence matrix formation means 2 reads the arrayed data for a protein Y out of a storage means 1 and forms a coincidence matrix A consisting of elements Aij, for various values of i and j, which shows whether the coincidence is secured or not between the i-th amino acid residue counted from an end of an array of N pieces of protein Y and the j-th amino acid residue counted from an end of a protein X consisting of an array of M pieces of amino acid residue. A consecutively coincident element extracting means 3 extracts only (n) pieces of elements or more (n>=2) which are consecutively coincident out of those elements appearing on an oblique straight line of the coincidence matrix A. A similarity degree calculation means 6 calculates a coincidence rate on an oblique straight line corresponding to the maximum coincidence rate Rm to define it as the similarity degree RH when a k-degree square matrix is quantized. As a result, the protein having a high similarity degree is retrieved objectively and at a high speed.
