Inventor: KANAZAWA HIROTAKA
IPC: B62D6/00
Filed: 1982-07-20
Abstract: PURPOSE:To increase steering ratio when running at high speed and improve steering stability by providing an elastic body and a damper within a steering linkage and changing the transfer characteristics of said damper in accordance with the car speed through an adjusting means. CONSTITUTION:Since a flow control valve 31 is not operated when a car speed is lower than the set value, the diameter of an orifice 29 is reduced by the second annular concave groove 37 of a spool 33, causing increase in the delaying action of the orifice 29 with steering ratio characteristics as shown by the line (a) in the figure. With a higher car speed above the set value, the flow valve 31 is operated to cause the diameter of the orifice 29 to be increased by the first annular concave groove 36 of the spool 33, and the delaying action of the orifice 29 is comparatively reduced with the steering ratio characteristics as shown by the line (b) in the figure. Thus, when running at high speeds, the responce of the wheels is slightly lowered to provide high steering stability.

Title: Manufacture of compound semiconductor element
Inventor: KASHIWADA YASUTOSHI
IPC: H01S5/00
Filed: 1983-07-15
Abstract: PURPOSE:To completely eliminate a crystal defect caused by the growth on the mesa showing a groove-form by starting the growth involving the formation of the growth layer just right on the mesa with the height of the mesa surface which is relatively higher than the surfaces of crystals around the mesa or is at least equal to them. CONSTITUTION:On an N-InP substrate crystal 19, four layers 20-23 are multilayer-grown by an usual liquid-phase growth followed by wet chemical etching using an SiO2 film 28 as a mask to form the mesa composed of the layers 20- 23. After that, layers 24-26 are obtained by buried-in growth under the condition that a height of the surface of a layer 26 is relatively lower than that of the layer 23. Next, the oxide mask 28 is removed and a contact layer 27 is obtained by liquid phase growth. The contact layer 27 has the InGaAsP composition in which a band gap energy is smaller than that of the cap layer 23 and it is capable of reduction of the contact resistance with the anode electrode arranged in the later element-fabrication process. However, the layer 27 can not be arranged in the position of the cap layer 23 because of its nature for an etching solution used for formation of the mesa.

Title: Image forming device
Inventor: SHINDO TATSUYA
IPC: G03B13/00
Filed: 1990-05-16
Abstract: PURPOSE:To prevent a flaw from occurring in the case of forming a next image and to reduce the running cost of a microcapsule paper by moving a dancer roller after finishing exposure and retreating a paper at a position where a driving roller does not come in contact with a nip roller. CONSTITUTION:At the time of finishing the exposure, the dancer roller 16e moves in a direction where it is initially positioned by the tension of the microcapsule paper 13. When a dancer roller position detecting sensor 16i detects that a dancer roller arm 16f comes to a specified position, the nipping of the nip roller 16b to the driving roller 16a is released. Thereafter, the paper 13 is fed to a point which exceeds a separation roller 17 a little, and then it is rewound. The unused part of the paper 13 is rewound to a position where the exposure is started on an exposing board 15 again. Even though the rewound part is exposed, an outputted image without the flaw is obtained and the running cost of a photosensitive recording medium is reduced.

Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a rare gas discharge lamp having a stable electric discharge, rarely generating a flicker of the electric discharge, having good radiation efficiency of ultraviolet rays even when power consumption is large, having a rarely saturated light output, and provided with an external electrode and to provide a rare gas discharge lamp lighting device and a lighting system using this discharge lamp. SOLUTION: An external electrode arranged on the outer face of a translucent discharge container 1 is used for at least one of a pair of electrodes 3, 4 arranged on the slender translucent discharge container 1 sealed with a discharge medium mainly made of rare gas and having the outer diameter D mm, thickness (t) mm and relative dielectric constant satisfying the formula 0.01<t/(D.ε)<0.05. When the electrostatic capacity of the translucent discharge container 1 is reduced and the impedance of the translucent discharge container 1 serving as a current limiting impedance is properly increased, a constant current circuit is obtained, thus an electric discharge is stabilized, and a flicker of the electric discharge rarely occurs.  When the outer diameter of the translucent discharge container 1 is increased to satisfy the above formula, the heat radiating area of the translucent discharge container 1 is increased, thus the temperature rise of a discharge medium is suppressed, and the light output is rarely saturated.
