Title: Semiconductor device
Inventor: HASEGAWA TORU
IPC: H01L23/00
Filed: 1988-11-22
Abstract: PURPOSE:To prevent the occurrence of blurred printing and the like due to physical factors by forming a recessed plane in the upper main surface of a resin case wherein a semiconductor element is contained, and performing printing on the plane. CONSTITUTION:A tray shaped recessed plane 1 is provided in an upper main surface of a resin case, i.e., a dual-in-line package(DIP) wherein a semiconductor element is contained. The name of the manufactured product, the name of the kind, the lot number and the like are printed on said plane 1. That is, a step is provided between the printed surface and the peripheral part. Thus poor printing (blurred printing) is positively decreased. Since the lower printing surface is provided, an advantage is to decrease the amount of use of resin. That is, when the printing surface of the present plane is made lower than the peripheral part, blurred printing is prevented, and the printing strength with regard to physical factors is increased.

Title: Damping device
Inventor: SHIRAHAMA KENJI
IPC: F16F15/04
Filed: 1993-11-26
Abstract: PURPOSE:To provide a damping device by which three-dimensional vibrations are absorbed and locking vibrations are absorbed and further, increase the degree of freedom in the arrangement of the device. CONSTITUTION:An intermediate foundation slab 7 is laid through a laminated rubber 11 supporting the vertical. load and allowing the horizontal vibration, on a foundation 5. And an upper foundation slab 9 is laid through springs 13 allowing the vertical vibration thereon and further thereon, a structure 1 is built. A plurality of oil dampers 15 are arranged between the upper foundation slab and the intermediate foundation slab to attenuate the vertical relative vibrations. The oil dampers 15 are used as a couple and the oil chamber 29 at the upper side of one of oil dampers is connected to the oil chamber 31 at the lower side of the other oil damper by means of a pipe 17. At a usual vertical vibration, the oil flows and attenuates normally, but at a locking vibration, since the volumetric changes between the upper and the lower oil chambers 29, 31 are different, it becomes difficult for the oil to flows and also for the oil damper 15 to do its extending and contracting movement and hence, true locking vibration is regulated And the degree of freedom of the pipe 17 connection is large.

Title: Calculation network
Inventor: PATORISU IWAN SHIMAADO
IPC: G06N3/063
Filed: 1994-11-09
Abstract: PURPOSE: To improve a responding time, and to construct a huge network with a wide range applied capability in a neural network. CONSTITUTION: A node output is truncated by the value of S2<n> ((n) is an integer, and S is +1 or -1). Thus, during forward propagation, the product of the node output and weight can be generated by a simple shift operation instead of a multiplying operation. The shift operation is used instead of the multiplying operation is used across a neural network so that a responding time can be improved, and a huge network with a wide range applied capability can be constructed. Also, learning can be improved by improving the efficiency of backward propagation. Multiplication included in the backward propagation can be changed to the shift operation by truncating an error accompanying each node. Thus, the error is displayed as S2<n> ((n) is an integer, and S is +1 or -1).
