Title: Internal pump
Inventor: OMORI MOTOTSUGU
IPC: G21C15/243
Filed: 1990-08-03
Abstract: PURPOSE:To prevent reactor cooling water containing a clad from penetrating into a pump and a motor by installing plural pieces of plate projections, heading for an outer circumference, on the lower end face of an impeller boss, and thereby forming a small pump there. CONSTITUTION:A vane 21 made up of a plate projection is installed in the lower end face of an impeller boss 14 being opposed to the upper end face of an inner cylinder 10 of a diffuser 11. Cooling water containing a clad is accelerated and fed, under pressure, by a pump shaft 3, the impeller boss 14 and an impeller 9 rotated and driven by a motor 6, and carried downward. In this case, part of a flow of the cooling water contained with the clad tries to penetrate into the inner part through a clearance 19, but it is repelled away to the outside by means of pumping action of the vane 21, no entering into a clearance 17 or 18. Accordingly, any possible penetration of the clad into a motor part is thus preventable. In this connection, the vane 21 may be installed in the inner cylinder of the diffuser.

Title: On-vehicle traffic information receiver
Inventor: SUMII SADAHIKO
IPC: H04B1/16
Filed: 1989-08-10
Abstract: PURPOSE:To prevent a broadcast of traffic information from being interrupted forcibly by discriminating an ON-operating time being a short or long time of a traffic information channel selection button, outputting a channel selection control signal accordingly and using the channel selection control signal so as to allow a traffic broadcast channel selector to select plural traffic information broadcast stations. CONSTITUTION:A traffic broadcast channel selector 15 connecting to a CPU 12 uses a control signal being ON for a long time T2 and for a short time T1 to apply channel selection of 1620kHz and 1629kHz. Then the traffic broadcast channel selector 15 applies channel selection of 1620kHz and 1629kHz alternately at each input of channel selection control signal and restores the original state upon the receipt of a restoration control signal. Thus, even when the electric field level of the reception signal of the traffic information broadcast station is weak, so long as a traffic information channel selection button 2 is not depressed, the traffic information broadcast is listened to till it is not heard without forcible interruption of the broadcast.

Title: Image input device
Inventor: MORITA KOICHIRO
IPC: G06K9/00
Filed: 1989-08-10
Abstract: PURPOSE:To obtain a wide finger print image free from trapezoidal distortion by using a curved glass for a finger print impressing part. CONSTITUTION:When no finger is put on the curved glass body 1-1, input light to an image sensor 1-2 is fully reflected, so that the output signal level of the image sensor 1-2 goes higher than a binary slice level and all output signals from a comparator 5 are turned to '0'. When a finger is put on the body 1-1, a value smaller than the binary slice level is obtained on the projected line part of a finger print. Thereby, the setting of a finger can be detected by observing the output of the comparator 5. In this case, an elastic thin film is applied to the inside of the curved glass body 1-1 to improve adhesiveness with projected line. Consequently, the finger print image of the finger put on the body 1-1 can be detected along the curved face.
