Title: Anti-seismic civil works and building works by spheres
Inventor: FURUHASHI NOBUYUKI
IPC: E02D27/34
Filed: 1990-08-17
Abstract: PURPOSE:To provide the degree of freedom between a building and a foundation as well as to reduce the propagation of shaking due to earthquakes and the like by forming the foundation of the building into each recessed spherical surface, and thereby supporting each projected spherical base section of the building by the aforesaid foundation. CONSTITUTION:A structural configuration where the projected spheres 1 of a building are supported by each recessed spherical surface 2 of its foundation, is employed in the foundation of the building, so that shaking due to earthquakes and the like is hardly transmitted to the building. Furthermore, shaking of W/9.8X2.50kg caused by maximum acceleration 250 gals in the case of the 5th degree on the seismic scale for example, its gravity component will be 1/9.8 of the aforesaid value when it is transmitted upward, since the projected sphere 1 goes up a slant, its acceleration is turned to be tantheta plus friction force (mu). As a result, when an angle becomes 30 deg., shaking force will be 17.6%, and when the angle becomes 60 deg., shaking force will be 5.8%, and resisting force is therefore increased as shaking is magnified. Furthermore, restoring force converges to WH joules as a height H is increased. Shaking thereby becomes low, because restoring force is increased.

Title: Sample holding circuit
Inventor: GOTOU KATSUHIKO
IPC: H02P29/00
Filed: 1982-12-13
Abstract: PURPOSE:To omit the use of a high reverse voltage-proof transistor (TR) by connecting a switching element to the base terminal of a TR through a resistor and earthing the base terminal during a period no sampling pulse is applied. CONSTITUTION:A switch 8 is connected to the base of a TR 17 through a resistor 23 and a reference voltage source 20 also is connected to the base through a resistor 22 and a diode 21. During no sampling period, the switch 8 is turned on and a fixed forward voltage is applied to the base of the TR 17. Consequently, the reverse voltage between the base and emitter of the TR 17 is reduced by the base voltage. During the sampling period, the switch 8 is turned off, the diode 21 is reversely biased and the reference voltage source 20 does not exert influence upon the titled sample holding circuit. Thus, the sample holding circuit can be formed without using an especially high reverse voltage-proof TR.

IPC: H04N5/335
Filed: 1982-12-13
Abstract: PURPOSE:To reduce 1/f noises, and to obtain a solid-state image pick-up element of a high SN ratio by forming a transfer gate MOSFET between a vertical signal line and a charge transfer element to a buried channel type.
