Title: Two rear-shaft type car
Inventor: MOMIYAMA FUJIO
IPC: B62D7/14
Filed: 1983-10-27
Abstract: PURPOSE:To secure the traveling stability by Pivot-connecting a tie-rod onto a pair of tie-rod arms which are fixed onto the knuckle of a steering rear-wheel shaft and extend rearward on the shaft, thus allowing a cornering force to be generated onto a rear wheel and providing a retaining strength to the rear- wheel shaft. CONSTITUTION:When a truck 10 turns leftward, the cut angle of an outside rear wheel 67 becomes predominant than an inside rear wheel 66 on turning, and the angle theta formed between the straight line connecting the center M of turn in low- speed traveling of the inside rear wheel 66 with the center of revolution of a steering rear-wheel shaft 33 and the axis line of the steering rear-wheel shaft 33 becomes the lateral sliding angle of the rear wheel 66. Then, a cornering force is generated onto the rear wheel 66 by said lateral sliding angle theta. Further, the cornering force serves as a retaining strength in the case when the steering rear-wheel shafts 33 and 34 are self-steered, and the always stabilized self-steering is permitted, and traveling safety is improved.

Title: Grape ice
Inventor: SUGANO YASUYUKI
IPC: A23G9/44
Filed: 1989-08-03
Abstract: PURPOSE:To obtain the subject grape ice having a fresh and raw food-like mouth feeling by taking off the pericarp of a Delaware seedless grape and freezing the resultant pulp. CONSTITUTION:An objective ice obtained by using a Delaware seedless grape as the raw material, taking off the pericarp of the grape, putting the resultant fruit grains in a vessel, tightly sealing the vessel and subsequently freezing the fruit grains. By the above mentioned process, the pericarp of the grape can be readily taken off from the fruit without damage to the pulp and process for removing the seeds can be omitted because of the absence of seeds in the fruit grain. In addition, because of a large quantity of juice contained in the fruit and softness of the pulp, a large amount of drip is generated in thawing the ice in the mouth and the tissue is softened without malaise and damage to its fresh and raw food-like mouth feeling. By combination of sweat taste with sourness, the taste of the ice can be diversified.

Title: Combustion suppression device for leaked liquid metal
Inventor: KAWADA KOSHI
IPC: G21C9/04
Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To suppress the combustion of leaked liquid metal by preventing splashing of liquid metal when it impinges onto floor liner owing to falling from a leak. SOLUTION: If a sodium pipe 2 on the floor of a building containing sodium components fails and liquid sodium leaks to fall down, it impinges on the floor liner 3 and splashes, which enhances combustion. Therefore, a combustion controlling device consisting of a partition structure 5 and a floor surface structure 6 is placed on the liner 3. The structure 5 partitions the liner 3 into a multitude of regions in grid wherein openings are provided to communicate so that the flow of the leaked liquid metal is assured to be led to a communication pipe 4. The structure 6 arranges structures of fine grid or mesh shape, etc. By this, fallen liquid sodium is finely separated by the structures 6 and 5 and contains in each grid, and so the amount of splashing and dispersing drastically reduces. Thus contact to the air is so reduced that combustion is suppressed.

Filed: 1986-08-27
Abstract: PURPOSE:To improve the stability of inclination by providing a pair of right and left oil pressure generating devices between a vehicle body and axles in the hydraulic stabilizer of a vehicle suspension device and controlling right and left stabilizer valves by means of the pressure difference between right and left oil pressures. CONSTITUTION:When a vehicle is inclined, a compression force acts on an oil pressure generating device 2 on the side on which a load is applied, contracting a spring 3. An oil pressure generating device 2 on the other side is adversely operated. The differentiated oil pressures in these right and left oil pressure generating devices 2 are introduced into the right and left chambers 7, 8 of a detecting cylinder 6, generating pressure difference in oil pressures in the right and left chambers 7, 8. Accordingly, a detecting piston 9 is moved right or left due to the pressure difference, rotating a stabilizer valve operating arms 12. Thereby, stabilizer valves 16 are rotated to vary oil pressures in right and left hydraulic stabilizers 1 to suppress inclination. By this structure, an inclination stability can be improved without need for using a special power, etc.

Filed: 1987-08-12
Abstract: PURPOSE:To decrease waveform distortions without providing a center tap to a magneto-resistance effect element (MR element) by using a nonlinear circuit having the nonlinearity of the reverse characteristic acting complementarily on the nonlinearity possessed by the resistivity/external magnetic field of the MR element which is not provided with the center tap. CONSTITUTION:The nonlinear circuit 7 having the nonlinearity of the reverse characteristic acting complementarily on the nonlinearity possessed by the characteristic curve of the MR element which is not provided with the center tap is provided. The intensity of the magnetic field acts on the MR element 1 connected to a current source circuit 3 and the distortion waveform which contains the DC component and is vertically asymmetrical in amplitude in correspondence to the nonlinearity of the rho-H curve possessed by the MR element 1 is blocked of the DC component by a capacitor 5 and is amplified to a required level by a preamplifier 6. The waveform is then passed in the nonlinear circuit 7 having the nonlinearity of the reverse characteristic which acts complementarily. The vertical asymmetry of the amplitude is thereby reverse corrected and is made approximately into symmetry. The reduction of the vertical asymmetry of the amplitude in the MR head of a two terminal type having no center tap within the circuit is thereby enabled and the signal quality at the time of signal reproduction is improved.

Title: Differential amplifier circuit
Inventor: TAKEUCHI MASARU
IPC: H03F3/45
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To ensure the input output linearity of the amplifier, while allowing the amplifier to have provision for a low voltage. SOLUTION: A negative voltage of a constant voltage source 34 is given to a base of a PNP transistor(TR) Q37, and a bias voltage Vb bringing the TR Q37 into saturation is provided to the TR Q37. A shunt current from a constant current source 32 is fed to an emitter of the Q37. The emitter circuit of Q37 is controlled, in response to a 1st input voltage VINA. When a base level of an NPN TR Q31 rises, the emitter current is fed to a resistor RA, and a collector current IC37 of Q37 is reduced more accordingly than for the case that no voltage exist across a resistor RA and then a base level of an NPN TRQ33 is reduced. Since a change in the collector current IC31 of Q31 is very small, a change in a base-emitter voltage VBE 31 is very small, thereby linearly controlling the emitter level of Q31.

Title: Optical recording and reproducing device
Inventor: NAKAMURA TOORU
IPC: G11B11/10
Filed: 1982-11-17
Abstract: PURPOSE:To improve the space efficiency of an optical recording/reproducing device by providing an optical deflector to an optical system and deflecting the incident luminous flux at a high frequency, and performing recording/reproduction during the scanning of an optical spot. CONSTITUTION:When a rotary mirror 11 turns slightly as shown by a broken line, the incident luminous flux of an objective lens 5 tilts as shown by a broken line. Thus the light spot on a recording medium 10 has a shift on an optical axis A. If the shift degree of the light spot is denoted as delta, the light spot oscillates + or -delta centering on the axis A when the mirror 11 has rotary oscillations by + or -theta. Then the medium 10 is shifted toward an arrow B rectangular to the oscillating direction of the light spot, and a locus C of the light spot is formed on the medium 10 as shown in the figure. That is, a disk revolving motor 9 is excluded by obtaining the relative speed between the medium 10 and the light spot from the scan of the light spot. In addition, the circular form is not necessarily required for the medium 10, and a rectangular form is also available. This can improve the space efficiency.
