Abstract: PURPOSE:To reduce the consumption of a working fluid by installing a pressure regulating throttle valve in the point midway in a working fluid supply-exhaust passage means between a pressure control means and an actuator, and making the working fluid so as to be unpassage unless differential pressure before and behind the said valve becomes more than the specified value. CONSTITUTION:In an actuator 10 being installed interposingly between a suspension arm to be installed at each wheel and a car body, an accumulator 30 is connected to a working fluid chamber 12 being partioned off by its piston 16 via a damping force throttle valve 28, and this working fluid chamber 12 is connected to the discharge side of a pump 36 via a passage 24, connecting passages 26, 25 and a pressure control valve 40 being controlled according to a vehicle running state. In this case, a pressure regulating throttle valve 52 is installed interposingly between these connecting passages 25, 26 at the downstream side of the pressure regulating valve 40. Passage resistance of this pressure regulating throttle valve 52 is set to be more than the passage resistance of the damping force throttle valve 28, while it is set so as to cause the passage resistance at the actuator contraction side to become smaller than that at the expansion side.

Title: Manufacture of semiconductor device
Inventor: NAGAO SHIGEO
IPC: H01L21/20
Filed: 1981-07-22
Abstract: PURPOSE:To realize a three-dimensional integrated circuit by forming a single- crystal Si layer on an amorphous dielectric made adhered to an Si substrate and providing various functional elements in this single crystal region. CONSTITUTION:An Si oxide film 6 is formed on a one main surface of an Si substrate 5 through thermal oxidation, and by using photoetching the Si oxide film 6 is selectively removed to regularly expose the Si substrate 5. The exposed Si substrate 5 with the Si oxide film 6 is then subjected to a hydrogen atmosphere at pressure below the atmospheric pressure and temperatures above 900 deg.C, forming a single-crystal Si layer 7 on the exposed Si substrate 5 while a poly-crystal Si layer 3 on the Si oxide film 6. The poly-crystal Si layer 3 is then dissolved by the laser or electron beam radiation. Because single-crystallization proceeds in a lateral direction from the side wall facing the single  crystal layer 7, a single-crystallized Si 4 can be formed.

Abstract: PURPOSE: To improve electric characteristics of a capacitor, by eliminating a recessed part developed in the central part of a lower electrode, and reducing a leak current. CONSTITUTION: A first interlayer insulating film 10 and, thereon, a second interlayer insulating film 11 which also serves as the stopper material of CMP are formed in order. Contact holes 12 are formed, and polysilicon films are formed to fill the contact holes 12. The polysilicon films are polished by CMP, and the thickness of the second interlayer insulating film 11 is made 30-100μm. Thereby, polysilicon plugs 14 having flat upper surfaces free from recess are formed. Lower electrodes (15, 16) formed on the plugs become films of uniform thickness free from recess.
