Title: Dot matrix type electronic timepiece
Inventor: ISHIKAWA TAKEHIRO
IPC: G09G3/04
Filed: 1979-09-13
Abstract: PURPOSE: To perform a matrix display with good balance by a method wherein the identification bits which can discriminate between a capital letter and a small letter are provided to decide the kind of the unit time information.  
     CONSTITUTION: The decimal counter of the 10sec digits generates the 10sec digit signal of 3 bits and the like and accesses the character generator such as ROM, etc. via an electronic switch 10 to generate the matrix display scan signal, thus, 10sec digits and the like are displayed in the small letters. On the other hand, the decimal counter 5 of 1min digits generates the one minute unit time information of 4 bits including the identification bit and accesses the character generator. As a result thereof, the time information such as one minute digits is judged by the character generator, thus, one minute digits, are displayed in the capital letters. By means of the capital letter display and the small letter display in accordance with these digits, the display of the good balance and easy to see is performed.

When a heavier load is applied, the connections of the switching devices SU1 -SU0 and SL1 -SL0 are also switched to maintain the electric power required by the load. Further, arbitrary number of capacitor modules MKK (M11 -MN1 ,... M1 N-MNM) which are divided into groups composed of N series-connected modules respectively are also selectively connected in series by controlling ON's/OFF's of switching devices SKK with control signals DKK.

Abstract: PURPOSE:To prevent the erroneous operation of a brushless motor drive circuit and to save the energy of the motor by varying the current of a current source which drives an output stage transistor of the motor in response to a control voltage and obtaining a drive current which corresponds to the output current. CONSTITUTION:Output stage transistors TrQ1A, Q2A are controlled at firing by switches S1A, S2A which are turned ON or OFF in the prescribed sequence by rotor position detection signals. When the input/output current ratio of the first current mirror circuit having TrQ3A, Q4A and the second current mirror circuit having TrQ5A, Q6A is set to 1:1, the drive currents I0 to the TrQ1A, Q2A become equal, the collector currents of the TrQ3A, Q5A become equal to those of the TrQ4A, Q6A, and the current I0 becomes substantially equal to the power source voltage VS. On the other hand, since the stator coil current is proportional to the voltage VS, the current I0 which is proportional to the stator coil current can be obtained, and suitable quantity of drive current can be always applied to the bases of the TrQ1A, Q2A.

Title: Semiconductor device
Inventor: NAKAMURA SHINJI
IPC: H01L23/28
Filed: 1989-05-11
Abstract: PURPOSE:To improve sealing performance by arranging a frame made of metal or resin on the periphery of a substrate, and performing resin sealing so as to come into contact tightly with the substrate and the frame. CONSTITUTION:A frame 8 made of metal or resin is arranged on the end surface of a substrate 6, and filled with sealing resin 7. Since the frame 8 acts as a casing, the sealing is completed only by making the sealing resin 7 flow from above. Hence the shape of the sealing resin 7 is stabilized, and the distance from a semiconductor chip 1 to the substrate 6 can be utilized to the utmost. When water content or the like permeates from the outside into a connection part of conductive adhesive agent 4 via an interface, the water content must pass the interface between the frame 8 and the sealing resin 7, and the interface between the substrate 6 and the sealing resin 7, so that the distance is lengthened. Thereby the sealing performance is improved.

Abstract: PURPOSE:To improve the accuracy of a diffusion test and to extend the ragne feasible for testing, by making a gas heavier or lighter than the gas to be tested throw into a wind tunnel according to the specific weight of the gas to be tested to air, and diffusing the gas through the wind tunnel with a raised flow speed. CONSTITUTION:In the wind tunnel test of a specified gas, the number of fields F has to be consistent. Therefore, when the specific weight of the specified gas to air is larger than one, another heavier gas is thrown into the wind tunnel, while, when smaller than one, another lighter gas is thrown to perform the diffusion test of the specified gas with a raised flow speed within the wind tunnel. By this means, as the measurement of the flow speed is made easy, the accuracy of the diffusion test is improved, and the range feasible for testing is extended.
