Title: Diversity receiver
Inventor: KIZU MASAFUMI
IPC: H04B7/08
Filed: 1990-01-25
Abstract: PURPOSE:To reduce a code error at the time of demodulation in a high speed digital communication by comparing a statistic quantity calculated based on a delay profile to select a directional antenna with the shortest inter-code interference time. CONSTITUTION:Directional antennas AT1-ATn are directed to a required direction to attain an angular diversity reception before and after a vehicle being an object such as a mobile object and then arranged. A statistic quantity calculation means 10 calculates the statistic quantity corresponding to an inter-code interference time by a multi-path based on a delay profile in correlation to the delay characteristic of multi-path as to the antennas AT1-ATn. A comparison means 12 compares the calculated statistic quantity of the antennas AT 1-ATn. An ECU 14 has a function of an antenna selection means. That is, the ECU 14 based on the result of comparison selects the directional antenna whose inter-code interference time is minimum due to multi-path based on the result of comparison among the antennas AT1-ATn. Thus, a demodulation data from the antenna with minimum inter-code interference time selected in such a manner is selected by a changeover switch 16.

Title: Differential pressure converter for high static pressure
Inventor: SHIMADA YOSHIO
IPC: G01D5/24
Filed: 1978-02-15
Abstract: PURPOSE: To make it possible to standardize differential pressure converting unit to a smaller size and to accurately detect the fine quantities of process variables such as pressure or liquid level by making such construction that only one half of the differential pressure metered is applied to the differential pressure converting unit of the converter.  
     CONSTITUTION: If high and static pressures PH and PS are applied through pressure inlets 1' and 1 of flanges 2' and 2, respectively, they are transmitted as internal  pressures to a pressure converting unit BH and a pressure converting unit BL through inner diaphragms 16 and 16' respectively. On the other hand, the pressure in the filled liquid 19 in the outer diaphragms 15 and 15' takes a value of (PH+PS)/2. As a result, the pressures to be applied to the pressure converting units BH and BL take the value ΔP/2 which is the half of the differential pressure. Since, in this way, the half pressure of the differential pressure is applied to the differential pressure converting unit, the converting unit can be standardized to a small size, and it is possible to provide a differential pressure converter which can detect the highly accurate pressure under a high static pressure of high range.

Title: Clock
Inventor: ONO YASUMASA
IPC: G04G5/00
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of operation required for time setting through such control as a time data is read out from a memory means when power supply is resumed and a time is set again. SOLUTION: When a user set 13 a time, a system control section 12 stores a set time data in a memory section 14 and counts the time from the set time data. When a battery is removed to interrupt power supply from a main power supply 15 to each part,, the control section 12 sustains the backup and count operation of time data through a backup power supply section 16. When a lithium battery or the like is removed to interrupt power supply from the power supply 16, the control section 12 stops the count operation of time data. When power is fed again to the control section 12 from the power supplies 15, 16, the control section 12 reads cuts a time data being set previously from the memory section 14 and brings about a time set mode using that data. Consequently, the amount of operation required for a user to set a time can be reduced.

Title: Oscillation circuit
Inventor: MOROKAWA SHIGERU
IPC: G04F5/06
Filed: 1979-02-16
Abstract: PURPOSE: To obtain a crystal oscillator which has the assured operation over a wide voltage range and with the low power consumption, by providing the simplified constant voltage source within the oscillation circuit.  
     CONSTITUTION: Transistors TR203 and 202 are connected via capacitor 212 to form the complementary reverse amplifier of a high amplification factor and then to give excitation to crystal 220. And the output of the crystal is extracted via the waveform shaping inverter circuit comprising TR223 and 224. The bias is given to TR201 by voltage division resistances 226 and 227, and the source-drain voltage is kept nearly at the threshold voltage. And the bias is given to TR203 via high resistances 205 and 207. The current of the same value flows to both TR202 and TR203 by the function of the current Miller. This current value is not effected by the fluctuation of the power voltage. As a result, the oscillation circuit can have the steady oscillation as long as the power voltage features 0.6V or more regardless of its drop.

Abstract: PURPOSE:To increase adhesive force between the metallic fitting for reinforcement and the adhesive, by metal plating the outer surface of the metallic fitting for reinforcement which is attached on the side surface of a Braun tube with an adhesive, and by leaving the inner surface as it is so that the active surface of the material of the metal fittings will be exposed. CONSTITUTION:A metallic fitting for reinforcement 3 is attached to the side surface of a Braun tube 1 with an adhesive 2. Then a tensile band steel 4 is wound over the metallic fitting to form an explosion-proof Braun tube. The outer surface of the metallic fitting for reinforcement 3 which is made of a material such as SPCC steel plate is anticorrosion-treated by a method such as zinc galvanization, whereas the inner surface is left as it is so that the active surface of the SPCC steel plate can be utilized. Thus, when the metallic fitting for reinforcement 3 is positioned in place using the adhesive 2, the adhesive force between the metallic fitting 3 and the adhesive 2 is greatly increased and antiexplosion characteristics can be improved.

Abstract: PURPOSE:To utilize efficiently the quantity of heat generated by a heating means by decreasing the wall thickness on the heating means side of a crucible enclosing the heating means. CONSTITUTION:The wall thickness on the heating means 4 side of a crucible 5 enclosing the heating means 4 of a device for melting a metal in vacuum deposition, etc. is decreased and the wall thickness on the opposite side is increased. Then, most of the quantity of heat generated from the means 4 contributes to heating of the crucible 5. The temp. decreases from the side of the crucible 5 near the means 4 toward the outside circumference. The temp. on the outside surface of the crucible 5 is thus made lower and the heat loss is decreased. The similar result is expected even by dividing the crucible 5 to plural pieces.
