Title: Manufacture of 3-dimensional semiconductor integrated circuit
Inventor: MATSUNAMI MITSUO
IPC: H01L21/8234
Filed: 1986-11-14
Abstract: PURPOSE:To increase remarkably the number of circuit elements to be formed, by joining the upper surface of a lower semiconductor single crystal layer and the lower surface of a upper semiconductor single crystal layer in the manner in which the two surfaces contact with each other, and forming the circuit elements on the upper surface side of the upper semiconductor single crystal layer. CONSTITUTION:A circuit element 5 is formed on the upper surface side of a lower semiconductor single crystal layer 1, and a circuit element 5 is formed on the lower surface side of an upper semiconductor single crystal layer 3. Then the upper surface of the lower semiconductor single crystal layer 1 and the lower surface of the upper semiconductor single crystal layer 3 are contacted with each other and joined. On the upper side surface of the joined upper semiconductor single crystal layer 3, a circuit element 5 is formed. The upper surface of the lower semiconductor single crystal layer 1 and the lower surface of the upper semiconductor single crystal layer 3 are usually joined after circuit elements 5 are formed and the surfaces are coated with insulative layers 4. In this case, electrodes of the circuit elements 5 formed on the respective semiconductor single crystal layers are once buried in the insulative layer 4, but they are connected to the upper layer afterwards by making through holes and the like from the upper semiconductor single crystal layer 3.

Title: Method for evaluating sound energy
Inventor: SHIMIZU HIROKO
IPC: A61F11/00
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To quantitatively evaluate a sound energy as a digital amount by setting one cycle of a sound of a specific frequency generated with a predetermined sound volume as a pulse value, and evaluating a pulse count which is a quotient of a generation time of the sound by the pulse value as the sound energy of the sound. SOLUTION: A hearing ability of a person who has difficulty in hearing is measured, and an acoustic characteristic of a hearing aid is set in accordance with the ability, whereby a remarkable correction effect is obtained. More specifically, one cycle of a sound of a predetermined frequency generated with a predetermined sound volume is set as a pulse value, and a pulse value, and a pulse count which is a quotient of a generation time of the sound by the pulse value is evaluated as an energy of the sound. For instance, when one cycle of the sound of 500Hz frequency is 1/500sec.=2msec. which is the pulse count, and the generation time is 0.2sec., the sound energy is evaluated to be 0.2/0.002=100 pulses. As the generation time becomes longer, the sound energy is increased.  However, the predetermined sound volume is not specifically limited and can be set to a degree whereby a person of normal hearing ability can hear without feeling discomfort.

Title: Waveform equalizer
Inventor: SAWAMURA HIDEHIKO
IPC: H03H17/00
Filed: 1992-10-13
Abstract: PURPOSE:To provide a waveform equalizer which can equalize the reproduced signal having a minimum code inverting interval of (d) bits (d>=2) by means of a transversal filter of a small number of taps. CONSTITUTION:A 5-bit transversal filter uses the delay elements 102 and 103 of the delay value dtau and the delay elements 101 and 104 of the delay value tauand multiplies the input/output signal of each delay element by a proper coefficient to obtain the desired filter characteristic. The circuit scale can be reduced and the conventional 6 adjustment points can be reduced down to 4 owing to a fact that number of taps of the transversal filter is reduced down to 5 from 7. Furthermore the range of equalization bands can be reduced by setting the minimum inverting interval at 2 bits or more for the code to be equalized.
