Title: Target selecting receiver
Inventor: SUZUKI KEIZOU
IPC: G01S3/789
Filed: 1983-11-04
Abstract: PURPOSE:To eliminate adverse influence caused by an unnecessary reflected wave or a jamming source, by forming a gate signal from a predetermined reference signal, a demodulation error signal and a gate width signal corresponding to the size of a target and extracting a target part from a receiving signal. CONSTITUTION:The receiving output modulated by a rosette scanning antenna 31 receives intermediate frequency conversion to be subjected to amplitude detection and converted to a video signal through a gate circuit 37. This signal is processed on the basis of reference signals 81, 82 formed of two sets of reference signals 1-4 different in angular frequencies synchronous to the antenna through first and second adders 110, 111 by a synchronous detection circuit 97 and azimuth angle and high angle error signals 25, 26 are extracted. On the other hand, a gate generator 112 forms and outputs a gate signal on the basis of the signals 81, 82 and 25, 26 and a set gate width signal corresponding to the size of a target to control the circuit 37. By this method, only a target is extracted and adverse influence due to an unnecessary reflected wave or a jamming source is prevented to extract the target with high accuracy. Furthermore, similar operation is performed even to the reception processing of an optical signal.

Abstract: PROBLEM TO BE SOLVED: To provide a foodstuff storage date and hour printing apparatus capable of managing and ascertaining, at sight, the stored date and hour for various kinds of foodstuffs to be stored, and serving to prevent food poisoning or the like. SOLUTION: This foodstuff storage date and hour printing apparatus 1 has an input unit 3 for inputting information on the date and hour, a sticking label 5 having a printing blank for such information and capable of being stuck to foodstuffs or to a package of foodstuffs, and a printing unit for printing the information on the date and hour and characters on the printing blank 6 of the aforementioned sticking label according to the information sent from the input unit 3, and for discharging the label thus printed. By using this apparatus, the information on the date and hour and the characters is printed by the printing unit on the printing blank 6 of the sticking label 5 in response to the information sent from the input unit 3, and the sticking label 5 thus printed is discharged.  By sticking the sticking label 5 having the information printed thereon to various kinds of foodstuffs to be stored or of packages of foodstuffs to be stored, the date and hour when the foodstuffs are stored can be ascertained at sight when the label 5 stuck to the foodstuffs concerned is visually examined in after days, in the case where these foodstuffs are put into and stored in a low- temperature foodstuff preservation apparatus. As a result, the time limit management for the stored data and hour of the foodstuffs becomes perfect, and food poisoning can be prevented.

Title: Front and rear wheel steering vehicle
Inventor: TOKUNAGA HIROYUKI
IPC: B62D101/00
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To suppress the unstable movement of a vehicle on a slippery road surface by calculating a value corresponding to the horizontal direction grip force of a front or rear wheel and changing the steering angle of the rear wheel in a direction for reducing a horizontal slipping angle as the horizontal direction grip force corresponding value approaches the limit of tire performance. SOLUTION: By turning a rear wheel 6 at a phase identical to that of a front wheel 1 in a front and rear wheel steering vehicle, the vehicle is turned before the generation of a car body slip angle by yawing moment. On a low ωroad, however, it is more difficult for a yaw rate to appear, and thus an under-steering tendency is provided. Accordingly, a driver excessively turns a steering wheel 2. When the horizontal force utilization rate of the front wheel 1 exceeds 1 because of such excessive steering, drifting-out occurs, and thus the rear wheel 6 is turned in a direction for reducing a slip angle as the horizontal force utilization rate of the front wheel 1 approaches 1.  Thus, since a yaw rate is established, the driver slightly returns the steering wheel 2 by recognizing turning-around, and thus the cornering force of the front wheel 6 is restored and a turning behavior is stabilized.

Abstract: PURPOSE:To clean a rotary head automatically by storing a cleaing tape in a storage cell for a cartridge which has the same width and shape with a magnetic tape, and running it on an oblique scanning rotary head surface and thus removing foreign matter. CONSTITUTION:The cartridge 13 for the cleaning tape 14 has the same constitution with a data cartridge and contains the cleaning type 14 having the same width with the magnetic tape. The cartridge 13 are stored in an optional number of storage cells at specific positions and the cleaning tape is wound around an oblique sanning rotary head 5 automatically at specific intervals of time according to a program as well as the storage cell for the magnetic tape and then run as well as the magnetic tape 2. In this case, the number of rotation of a rotating ring 6 is decreased to reduce the amount of floating of the magnetic tape 2, thus bringing it into contact with the magnetic head 5. During a run of the cleaning tape 14, no signal is transmitted and received, so the operation is completed in a short time. Therefore, the cartridge 13 are taken out in specific order to clean the rotary head automatically.
