Title: Disc player with magazine
Inventor: HERUMUUTO RAUFUAA
IPC: G11B17/30
Filed: 1987-11-13
Abstract: 1. Disk player with a magazine 2.1. A known compact-disk player with a magazine consisting of several superimposed compartments for accommodating compact disks has a system of levers and a pulley driven by an electric motor in each compartment for removing a disk from the compartment. 2.2. To decrease the considerable expense for each compartment (2) in the magazine (11), there is an access opening (15) on the rear wall of each compartment, through which a plunger (4) can travel to thrust the compact disk (7) out of the compartment. The plunger can be a flexible shaft that extends forward from the rear wall of the magazine through a tubular guide (3) and along one side of the magazine. The plunger can be introduced into and extracted from the compartment by means of a toothed rack (14) secured to the front of the flexible plunger (4) in conjunction with the cogwheel (10) that is driven by an electric motor (6) and engages the rack. 2.3. When embodied in a compact-disk player the invention is especially appropriate for installation in a motor vehicle. 2.3. Figures 1 and 2.

Title: Magnetostatic wave s/n enhancer
Inventor: KURATA HITOYOSHI
IPC: H01P1/23
Filed: 1994-11-18
Abstract: PURPOSE: To provide a magnetostatic wave S/N enhancer for which signal attenuation is small and to reduce burdens on an amplifier by making a saturation power threshold value for generating the power limitation effect of a magnetostatic wave filter different between a first magnetostatic wave filter and a second magnetostatic wave filter. CONSTITUTION: Signals inputted from an input terminal 1 are divided with the power ratio of 1:1 by a directional coupler 2 and the divided signals are inputted to the magnetostatic wave filters 3 and 4. In this case, the saturation power threshold value of the magnetostatic wave filter 3 is set at -25dB and the saturation power threshold value of the magnetostatic wave filter 4 is set at -5dB. Thus, the magnetostatic wave filter 3 performs a nonlinear operation because the power lamination effect works for the signal components above the saturation power threshold value of the signals inputted to the magnetostatic wave filter 3 and the magnetostatic wave filter 4 performs a linear operation because the power limitation effect does not work for the signals inputted to the magnetostatic wave filter 4. The passing signals of the magnetostatic wave filter 4 are converted to an opposite phase and then, synthesized with the passing signals of the magnetostatic wave filter 3 with the power ratio of 1:1 in the directional coupler 7.

IPC: H03M7/30
Filed: 1985-12-20
Abstract: PURPOSE:To reduce average encoding-distortion without causing a large degree of deterioration in the quality of a picture by providing two stages of quantization processes which are vector quantization and a scalar quantization processes, and controlling the number of bits to be allocated to the scalar quantization in the second stage. CONSTITUTION:A representative vector that is closest to a significant block selected by a significant block detecting circuit 8 that is a picture block to be encoding-transmitted, is selected by a vector quantizer 9, and a vector- quantization error is obtained by a subtraction circuit 10. From such an error signal, an in-block error signal power is calculated by a vector-quantization error calculation circuit 11. From the result of the above calculation and the state of the information-storing quantity of a buffer memory 18, an encoding control circuit 12 determines the quantity of codes allocated to a block currently encoded and a bit-distribution table used to distribute the said quantity of codes to respective picture elements in the said block. In a scalar quantizer 13, the vector-quantization error signal is quantized, and outputted through a multiplexing circuit 17 and the buffer memory 18.

IPC: B62D63/02
Filed: 1987-11-12
Abstract: PURPOSE:To make it possible to climb stairs with a simple structure by cranking a wheel frame so as to secure a wheel attached to this frame at a 90 deg. turn angle position. CONSTITUTION:Front wheels 6 are arranged to be directed perpendicular to the running direction in association with a manipulation of a steering wheel 4. Wheel frames 12 are coupled to both sides of a vehicle body through cranks 11 in its front section and through driven shafts 13 in its rear section. Accordingly, during climbing stairs, the front wheels 6 are directed in a direction perpendicular to the running direction so as to allow the front wheels to make into frictional contact with the upper surface of a stair 20. Then, the crank 11 is rotated, a circular track rotating motion is effected in the front end parts 14 of the cranks 11, and the front wheels similarly carry out a circular track rotating motion. Since the front end parts 14, 14 of the right and left cranks 11 are shifted by an angle of 180 deg. in phase, the right and left wheels 6 advance alternately so as to make into frictional contact with the upper surface of the stair 20, thereby is is possible to allow the vehicle body to climb stairs.

Abstract: PURPOSE:To constitute with less number of memories even when the data size of a data bus is large by time-dividing data in order to match with the data size of the memory, outputting them to the memory, connecting the data being time-divided and outputted from the memory, and outputting them to a data bus. CONSTITUTION:A data selector 4 time-divides data through a data bus 3 larger than the data size of a memory 2 in order to match the data size of the memory 2 in a write cycle and outputs them to the memory 2. A data latch 5 connects the data outputted by the time-division from the memory 2 in a read cycle and outputs to the data bus 3 with matching with the data size of the data bus 3. A column address strobe control circuit 6 operates the memory 2 by the number of times to be time-divided in the write cycle and the read cycle. Thus, even when the data size of the data bus 3 is larger than the data size of the memory 2, a constitution with less number of memories can be executed.

Abstract: PURPOSE: To provide high rigidity by forming a quadrangular pyramid as a stable structure by eliminating looseness of the pin joining part by keeping a balance state of force by generating compressive force in a rib by a wire tensioned between the mutual respective apexes to form the quadrangular pyramid. CONSTITUTION: A structure is unfolded by push-expanding a space between a main slide hinge 11 and a synchronous slide hinge 14 by spring force of a coil spring 17.

Looseness of the pin joining part is eliminated since this wire 13 presses a connector 3 to the four rib 12 side. High rigidity can be easily obtained by forming a loosenessless structure by tensioning the wire 13 between the respective quadrangular pyramid apexes.
