Abstract: PURPOSE:To perform continuous reception of 120-300MHz by using two varactor diodes connected in series and parallel to tuning coils of the input circuit, interstage circuit and oscillating circuit of a tuner which receives even the CATV band. CONSTITUTION:An input signal of VHFTV is inputted from a terminal (a), passed through an IF trapping circuit (c), and RF-amplified by a MOSFETQ1, and through cascaded transistor (TR)Q2 and Q3 for a mixer, an IF output converted by a TRQ4 for oscillation is outputted to a terminal (b). High-frequency tuning coils L1-L2 are each switched between a high and a low band through a switching diode SWD. To coils of an input, an interstage and an oscillating tuning circuit, varactor diodes CD1 and CD2 are connected in parallel and in series respectively, and then varied by an output from a power terminal Bt for tuning. This constitution provides continuous reception of the CATV band of 120-300MHz.

Title: Multiple electronic computer system
Inventor: OOTA KATSUMI
IPC: G06F15/16
Filed: 1978-07-07
Abstract: PURPOSE: To make it possible to know easily the state of the other electroic computer system.  
     CONSTITUTION: Now, a parity error is supposed to occur to main memory unit 12 of electronic computer system 10, causing a fault. As a result, content 17 of one bit at address A1 of shared memory 30 is rewritten from "1" for a normal stage into "0" and electronic computer system 20 is interrupted. When this interruption occurs, the program of this sytem 20 is available for the detection of the fault state of one- bit content 17 by reading out the content at address A1. The fault of system 20 can also be detected at the system 10 side in the same way. Consequently, the state of the component element of the party electronic computer system can be checked only by interrupting it once, and the backup process, etc., of the functions of the party electronic computer system can also be simplified.

Title: Recovering method of acetic acid
Inventor: KOGA KUNIO
IPC: C07C51/48
Filed: 1981-05-29
Abstract: PURPOSE: To recover acetic acid with a little energy advantageously, extracting the acetic acid from an aqueous solution thereof with a mixed solvent in which the distribution coefficient of the acetic acid, the selectivity of the acetic acid for water and the boiling point thereof are combined under specific conditions, and distilling and separating the resultant extract.  
     CONSTITUTION: Acetic acid is extracted from its aqueous solution 1 with a mixed solvent 2 which is a mixture of a solvent having a higher boiling point than the acetic acid with a solvent having a lower boiling point than the acetic acid, and the component having a lower distribution coefficient in acetic acid has a higher selectivity for water than the other component e.g. a mixed solvent of diisobutyl ketone with ethyl acetate or isophorone with benzene. The acetic acid 9 is then separated and recovered from the resultant extract 3 by the distillation. In the process, the solvent having the lower boiling point than the acetic acid is first removed in the dehydrating step, and the acetic acid concentration in the extract is increased to improve the separability of the acetic acid in the next recovering step of the acetic acid and reduce the thermal load of evaporation due to the solvent having the higher boiling point.

Title: Automatic assembly method of parts
Inventor: NAGASAWA SHIGEO
IPC: B62D65/00
Filed: 1985-04-19
Abstract: PURPOSE:To perform insertion work in a short time, by providing bright points in three places of a part mounting region while detecting the bright points in the three places through two camera units in a different mounting position and calculating coordinate values in the space. CONSTITUTION:When an assembly hub surface is three-dimensionally displaced, three of the assembly hub bolts 5 provide in their bolt top parts bright points 6 by white paint or the like. The method calculates a position of the hub surface in the space and a rotary angle of the hub bolt 5 only by optically measuring said three points through two sets of camera units. While when the center of the assembly hub surface can be determined, the top part in one of the assembly hub bolts 5 provides the bright point 6 by the white paint or the like. The method, optically measuring this one point by one set of camera unit, calculates the rotary angle of the hub bolt 5. Accordingly, automatization of assembly can be promoted by enabling an insertion material to be optically guided with the bright point 6 serving as the target.

In the case of using an O2 sensor, the gas sensitive film employs a metal such as Ag and Pt, a metal oxide such as Ga2O3 or the like. For other gas sensors, appropriate gas sensitive films are used. Otherwise, the insulation film 5 may be covered with a gas sensitive layer 4 and then, the gas diffusing layer 7 and the gate electrode 3. Thus, a stable sensor can be obtained with a faster response.
