Inventor: FUJITA MASAHIRO
IPC: G06F17/50
Filed: 1991-02-20
Abstract: PURPOSE:To obtain the deciding system of optimum variable order for case separation by comprising a system in such a way that a logical expression representing a logical function can be simplified by developing to a sum of products format, and the order of a variable with many product item numbers is set as a variable order when a binary decision graph for two-stage logic circuit is generated. CONSTITUTION:Firstly, the logical expression representing the logical function for two-stage logic is developed to the sum of products format, and is simplified at step 1. The product item number in which each variable appearing in the logical expression is used in an affirmative or negative format is checked, respectively at step 2, and the variable order when the binary decision graph is generated is decided according to an order of more product item numbers at step 3. When the variable appears in the affirmative format in the product item, it is expressed, for example, as 1, and as 0 when it appears in the negative format, and (-) when no variable appears, and the variable with more numbers of 0 and 1 is set as the variable order of the binary decision graph by counting the numbers at every column.

Title: Telephone set
Inventor: KOBAYASHI HIDEKI
IPC: H04M1/60
Filed: 1995-02-15
Abstract: PURPOSE: To adjust a reception sound volume properly according to a listener's preference without a special operation. CONSTITUTION: Voice of a talker is picked up by a microphone 11 and amplified by a microphone amplifier circuit 12. A signal level after amplified is held by a sample-and-hold circuit 19. A voice signal of an opposite party sent from a line 14 is amplified by a loudspeaker amplifier 17 and sounded from a loudspeaker 18. The gain of the loudspeaker amplifier circuit 17 is revised depending on the output of the sample-and-hold circuit, that is, the amplitude of a voice of the talker. When the voice of the opposite party is hardly heard, it is natural that the voice spoken by the talker tends to get larger. When the voice of the talker is larger, it is discriminated that the talker is hard to hear the voice of the opposite party and the reception sound volume is increased depending on the tendency above.

Abstract: PURPOSE: To uniformly form a dense Si 3 N 4  film directly on the surface of silicon by heat treating a silicon substrate in gas plasma atmosphere containing N 2  or mainly N atoms.  
     CONSTITUTION: After a silicon substrate cleaned on the surface is introduced into a reaction tube and substituted with N 2  gas, NH 3  is flown in predetermined flow rate through the tube and a high frequency voltae is applied thereto to produce NH 3  plasma atmosphere therein. At this time the substrate is retained at 800W 1300°C. After predetermined time, the high frequency voltage is stopped. After the tube is cooled for predetermined time in N 2  gas, the NH 3  flow is stopped and N 2  gas is introduced into the tube. When the substrate is pulled out of the tube after predetermined time, dense Si 3 N 4  film is uniformly formed on the surface of the substrate. This film exhibits strong oxidation resistant and impurity mask properties. In addition to the NH 3  gas, there may be employed N 2 H 4 , N 2  and H 2  mixture gas, N 2  and HCl mixture gas, N 2  and halogen mixture gas or mixture of any of these gases with gas which is substantially inert therewith.

Title: Pattern detection circuit
Inventor: HASHIBA KIYOSHI
IPC: H03K5/19
Filed: 1990-02-07
Abstract: PURPOSE:To suppress the increase of circuit scale by reading out a memory with input data and the value of a counter showing the order of the data as addresses, and outputting whether the input data is coincident with a detected pattern or not. CONSTITUTION:A memory 23 stores a binary signal showing whether the input data is coincident with the detected pattern or not. This memory 23 is read out with the data of a terminal 11 and the count value of a counter 21 as the addresses. Therefore, when the data of the terminal 11 is coincident with the corresponding part of the detected pattern, '1' is read out from the memory 23. When the data is not coincident, '0' is read out. When the binary signal '0' showing dissidence is inputted even once, a holding circuit 24 continuously outputs a signal corresponding to this binary signal and when the above mentioned binary signal is not inputted, a signal is outputted corresponding to the signal '1' showing coincidence. Therefore, the configuration of the holding circuit 24 is regardless of the detected pattern length and further, the circuit can be easily constituted while reducing the scale.

Title: Method and device for analyzing limit element in three-dimensional flow, manufacture of molding and medium recording analytical method program
Inventor: MITANI TETSUO
IPC: G01M10/00
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To find out a flow rate and pressure in a three-dimensional(3D) flow on the same grating point and to easily calculate the movement of a free surface by executing repeat calculation for finding out the flow rate and pressure by using respectively specified momentum expression, pressure expression and speed correction expression and finding out the flow rate and pressure on the same node. SOLUTION: A momentum expression discretized on the basis of a control volume method, a pressure expression obtained by discretizing a pressure term after substituting a momentum expression half discretized by removing a pressure term for a discretized continuous expression and a speed correction expression derived from the discretized momentum expression are used. Thus repeat calculation for finding out a flow rate and pressure is executed to find out the flow rate and pressure on the same node. Calculation can be stably executed by using the pressure expression in which a solution derived from the momentum expression and the continuous expression by executing discretization based on the control volume method does not generate spatial vibration and accurate calculation can be executed even in the case of using comparatively rough element division.
