Title: Formation of logical circuit pattern
Inventor: ICHIKAWA TAKAYUKI
IPC: G06F17/50
Filed: 1991-07-23
Abstract: PURPOSE:To easily form a logical circuit where noise owing to the operation of a pull-down transistor is reduced by selectively synthesizing a basic pattern with a pattern cell so as to form an SPL gate pattern. CONSTITUTION:For forming a wired OR circuit, the output terminals of plural logical circuits 50A-5OC are connected. In the logical circuit 50A, the pull-down transistor Q42 and a load resistance RL are participated in a circuit operation and are operated as an SPL gate when the basic pattern cell and a modifier pattern cell are synthesized. In other circuits 5OB and 50C, the pull-down transistor Q42 and the load resistance RL are detached from the circuit by only using the basic pattern cell and they are equivalently set to be an NTL gate. Thus, the selective arrangement wiring of the NTL gate and the SPL gate becomes possible in the formation of wried OR.

Title: Electronic part mounting equipment, part recognition method and device thereof
Inventor: IMOTO TAKUYA
IPC: H05K13/04
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To reset an electronic part at a certain angle of orientation at which it can be recognized without shutting down an electronic part mounting equipment for a long time, by a method wherein a relative angle of orientation of an electronic part is changed with a recognition execution angle by an angle of 90 deg., and then the part is recognized again. SOLUTION: When an electronic part mounting equipment 1 is not capable of recognizing an electronic part S with a part recognition camera 32 or the like (part recognizing means), a relative angle of orientation of an electronic part, such as a feed angle of a part feeder 4 or a suction angle of a mounting head, is changed with a recognition execution angle by an angle of 90 deg., and a recognition operation is carried out again by the equipment 1. By this setup, when the feed angle of a part from the part feeder 4 or the like is changed by an angle integer times as larger as 90 deg., the part can be recognized. Therefore, even if the mounting direction of a part tray is set different by an angle of 90 deg. by a wrong operation done by an operator, a time and man-hours wasted for returning a large number of trays to an initial prescribed angle can be saved, and an electronic part mounting equipment can be prevented from being shut down for a time required for a reset operation.

Title: Transmitter of still picture
Inventor: YONEMOTO EIJI
IPC: H04N19/50
Filed: 1983-11-02
Abstract: PURPOSE:To eliminate buffer memory and to shorten time transmitting data by decoding a variable length DPCM code together with data transmission. CONSTITUTION:A video signal from a camera is stored in a picture memroy 2 through an A/D convertor 1. A controller 10 activates a transmitting circuit 9 and a variable length DPCM encoding circuit 3 at the same time. Due to the activation an address control 5 outputs a scanning address to the memory 2, and supplies contents of the memory 2 to an encoder 4. An output of the encoder 4 is sent to the transmitting circuit 9 through a variable length/fixed length conversion circuit 6. On the other hand, when a final decision circuit 11 detects the final scanning of the memory 2, the circuit 11 transmits a transmitting termination signal to the transmitting circuit 9. As a result, a variable length DPCM code is encoded together with data transmission. Thus buffer memory can be eliminated and time for data transmission can be shortened.

Title: Electroacoustic transducer
Inventor: JIERII JII RIICHI
IPC: H04R1/22
Filed: 1981-12-21
Abstract: PURPOSE: To prevent the undesired reflection of the acoustic energy in an easy way, by  decreasing the small tungsten particles toward the direction further away from the  junction face between the tungsten particles and the piezoelectric elements that form a  sound absorbing substrate.  
     CONSTITUTION: A sound absorbing substrate 2 is formed with settled substrate layers  4, 6, 8 and 10, and tungsten particles P 4 , P 6 , P 8  and P 10  contained in the substrate  layers become larger as they move further away from the layer 4. The 1st piezoelectric array comprising piezoelectric elements X 1 ∼X 5  is adhered to the substrate 4, and  gold, etc. is deposited in the form of a thin film at the lower part of the piezoelectric  elements to reduce the contact resistance. Furthermore a conductor layer 12 is deposited on the layer 4. Then the 2nd piezoelectric array comprising piezoelectric elements X 1 '∼X 5 ' which are shorter than the elements X 1 ∼X 5  is put on the 1st piezoelectric array to hold conductor layers C 1 ∼C 5  between, and a matallic layer L of an  earth electrode is stuck on the 2nd piezoelectric array. The weight density of the  tungsten particles distributed within the substrate 2 becomes constant, and the junction  face can be formed extremely flat since the particles near the junction face are small.  In such way, the undesired reflection can be prevented in an easy way.
