Title: Method and device for measuring separateness with laser beam
Inventor: YASUO HIROYUKI
IPC: G01C3/22
Filed: 1991-11-13
Abstract: PURPOSE:To determine the closest distance (separation) of an aerial from a tree accurately, quickly, and simply. CONSTITUTION:A distance to an object is determined in the period of time from a beam of pulse laser being cast onto the object till the reflected beam coming back. The reflected light by the inner surface of a collimator lens 17 is led to a photo-receiving element 15 to determine the outgoing timing, while the reflected light by the object is led also via the collimator lens 17 to the photo-receiving element 15 to determine the timing at which the reflected light comes back. The pulse waveform is differentiated to determine the timing of being incident into the photo-receiving element 15, and the timings at which the reflected light and emitted light are left incident into the photo-receiving element are determined strictly. The position of aerial is measured at three points, and the result is approximated by a second order function or cosh function, and thereby the closest distance from tree is determined.

Title: Injector for magazine
Inventor: HORIGUCHI HIDEO
IPC: G11B25/04
Filed: 1994-12-27
Abstract: PURPOSE: To reduce the size of an injector for magazine while ensuring the injection distance. CONSTITUTION: The injector injects a magazine 1 inserted into a magazine loading part 52, in the direction opposite to the inserting direction. A magazine side rack gear 42 is provided on the outer side face of the magazine 1 while a fixed side rack gear 66 is provided at the magazine loading part 52. A pinion gear 68 meshing the fixed side rack gear 66 is provided movably in the inserting/removing direction of magazine and urged in the injecting direction by an urging means 71. Since the magazine side rack gear 42 meshes the pinion gear 68 upon insertion of magazine, the pinion gear 68 requires a moving distance substantially one half of that of the magazine 1. With such arrangement, the injector can be reduced in size in the inserting/ejecting direction of the magazine 1 while ensuring the injection distance thereof.

Title: Display unit for vehicle
Inventor: TANAKA KENICHI
IPC: B60K35/00
Filed: 1990-11-28
Abstract: PURPOSE:To decrease the rate at which passenger feel sick by displaying an image in a position opposite to the direction of acceleration at the center of a display portion when acceleration in the rightward or leftward direction of a vehicle is detected, and displaying to passengers the image of a posture by which passengers are free from feeling sick, and making the passengers have the posture on the image CONSTITUTION:When e.g. a vehicle makes a turn to the left at high speed or makes a turn at a curve of a small radius, rightward acceleration greater than a predetermined value is detected by a detector 1. A positive voltage signal greater than a predetermined value is then output from an amplifier 2. As a result, a voltage signal is inputted from a comparator 3 to an image memory 4a and a display unit 7 displays the image of the upper body of a passenger greatly leaning to the left. When the vehicle goes straight either rightward or leftward acceleration is not detected and the value of a voltage signal output from the amplifier 2 becomes zero and the voltage signal is inputted from the comparator 3 to the image memory 4c. As a result the display unit 7 displays the image of the upper body being straightened. By the above operation, the postures by which passegers are free from feeling sick are displayed to the passengers.

Abstract: PURPOSE:To achieve measurement of a signal and decision on the propriety thereof with a high accuracy, by a method wherein high-speed S/H circuits are connected in series by two stages to generate an envelope waveform and in order to generate positive and negative envelope waveforms, this system is arranged in two stages. CONSTITUTION:A signal A to be measured is inputted into sample holding circuits 4 and 6 through a band pass filter 2 or not and outputs thereof are outputted to sample holding circuits 5 and 7 and both thereof undergo a data analysis with a CPU 19 through a differential amplification circuit 17 and an A/D converter 18. On the other hand, a phase conversion circuit 9 converts a signal to be measured into a pi/2 phase and a timing signal is generated based on a logical signal obtained through a voltage comparator circuit 10 to control a sample holding circuit 4-7. This enables highly accurate processing of a peak value in real time, thereby automatizing the measurement and adjustment of a signal and decision on the propriety thereof.

IPC: H04L12/42
Filed: 1988-12-27
Abstract: PURPOSE:To improve the utilizing efficiency of a time slot even in the case of the extension of a system and to eliminate the interruption of the system by so devising the system that a control station collects time slots not in use at the extension of the system and the slots are allocated to an extended station. CONSTITUTION:When an extension station STNn 3-n participates in a loop system via a normal procedure, the station sends the allocation request of a time slot(TS) to a control station SVS 1. Upon the receipt of the request, the control station 1 decides whether or not there is a TS corresponding to the allocated slot in a margin TS in its own station. When the TS exists, the TS on request is allocated to an extension station 3-n. When not in existence, the control station 1 collects the deficient TS from communication stations (3-1)-(3-m) in operation at present. When the number of idle TS is less than the requested number, the number of TS up to the lower limit in which no hindrance takes place in the system is returned to the control station 1. The control station 1 allocates the collected TS to the extension station 3-n.
