Title: High-performance sound wave absorbing material
Inventor: KONO RYUSUKE
IPC: C09K3/00
Filed: 1988-05-11
Abstract: PURPOSE:To provide an inexpensive water-insoluble sound wave absorbing material having a large damping constant and excellent capability of absorbing sound waves by constituting it mainly from a water-soluble polar polymer. CONSTITUTION:This high-performance sound wave absorbing material is constituted mainly from a water-soluble polar polymer. An example of a process for producing this material adding an aqueous oligomer solution such as an alkaline aqueous urea oligomer solutionor an aqueous solution of a thermosetting prepolymer of a phenolic resin to an aqueous solution of polyvinyl alcohol, adding a curing agent (e.g., weakly acidic lignin) to the combined solution and forming the mixture into a sheet by rolling. As compared with a porous air- permeable soft polyurethane foam, the obtained sound wave absorbing material has a larger damping constant and better absorptivity, while its specific acoustic resistance differs little from that of the former.

Title: Semiconductor device
Inventor: INOUE TOSHIBUMI
IPC: H01L27/088
Filed: 1982-07-02
Abstract: PURPOSE:To minimize the leakage current at the time of usage as an input pin, by connecting a plurality of MOSFETs which are connected to a diode and a driving MOSFET between a terminal and an other power source voltage in series, and setting the sum of the threshold voltage of the MOSFETs so that the sum becomes the value at the intermediate part between the two levels that are supplied to the terminal. CONSTITUTION:When a power source voltage Vpp such as +25V is supplied to a terminal 2, the output of an inverter 11 is made to be a low level. An output signal -WE is synchronized with a signal -OE and changed to the low level in a similar manner. When said signal -WE is supplied to a MOSFET Q10, a level converter circuit 1 comprising the MOSFET Q10 and MOSFETs Q1-Qn is made to be operated as a kind of an inverter. A potential VDn at a node (a) becomes VD(n-1)-Vthn(VDn), where (n) is the number of the MOSFETs Q1-Qn. By setting the number of the MOSFETs Q1-Qn and characteristics (threshold voltage W/L ratio and the like) appropriately, the potential of the node (a) can be made to have a desired value.

Title: Spiral fin
Inventor: OGURO TOMOKATSU
IPC: F28F1/36
Filed: 1985-05-29
Abstract: PURPOSE:To improve the heat dissipation effect by enlarging the ratio of the outer diameter and the inner diameter of a fin, by a method wherein many notches are provided at the outside circumference of a spiral in the fin which is molded to the spiral type by rolling a metallic stripe etc. CONSTITUTION:Thin walled parts 3d, which extend from middle thin walled parts towards outside further to the outer diameter D3 at the nearly the same width t3 with the width t2 of middle walled parts 3c, are formed. Plural number of notches are provided at thin walled parts 3d to the radius direction, and, hereby, many of fin end parts 3f are formed. Since there are notches 3e at thin walled parts 3d, the molding power while rolling to the spirals generates only at the rolling from thick walled parts 3b to middle thin walled parts 3c, namely D1-D2, and the outside diameter D3 of the spiral 3 can be formed large without being effected to the spiralization even if the width t3 of thin walled parts 3d (in the sphere of D2-D3) are nearly the same to the width t2 of middle thin walled parts 3c. Thereby, it is possible to make the value D3/D1 above 2.0.
