Patent JP-H03141799-A (JP)
Title: Loudspeaker system
Inventor: NEZU MASARU
IPC: H04M9/00
Filed: 1989-10-27
Abstract: PURPOSE:To obtain a loundspeaker appropriate for conferences by arranging one or more microphones in each zone divided set up in each position when plural persons are to hold a conference or the like in the same space area, distributing a collected voice signal to the zones and generating the loundened voice from speakers arranged in respective zones. CONSTITUTION:A voice signal outputted from each zone is supplied to the mixers 4 (4B to 4E) of zones other than the self-zone. Namely when the voice of a speaker in the zone A e.g. is supplied from the mixers 4B to 4E in the zones B to E, the loudened voice is generated from the speakes SB to SE. On the other hand, attendants in the zone A can listen the contents of the speaker in the zone A by his natural voice. Since voices collected by the microphone M in the zones other than the self-zone is outputted from each speaker, a sufficiently large howling margin (high safety loud-speaking gain) can be obtained. since a signal processing part 2 is provided with an expanding processing circuit and a compressing processing circuit, level conversion processing can also be attained.

Filed: 1990-10-17
Abstract: PURPOSE:To secure the instantaneousness in fuel injection control by installing an air feed quantity estimation device, load estimation device, advance angle estimation device and an ignition control signal generator. CONSTITUTION:The effective feed quantity of the air supplied into a combustion chamber is obtained through the fuzzy estimation according to the feed quantity of the air supplied into the combustion chamber of the engine and the oxygen concentration in exhaust gas. The load applied to the engine is obtained through the fuzzy estimation according to the engine revolution speed calculated from the crank angle and the oxygen concentration in exhaust gas. The advance angle is obtained through the fuzzy estimation by an advance angle estimation device 35 according to the effective supply quantity of the air supplied into the combustion chamber, knocking information and the load. An ignition control signal generator 71 generates the ignition control signal at the corrected ignition timing which is obtained through the correction according to the obtained advance angle, and inputs the detected cylinder information to an ignitor 61 installed on the judged cylinder. Accordingly, the instananeousness for the ignition control can be secured.

Title: Semiconductor memory device
Inventor: MATSUZAKI YASURO
IPC: H01L29/792
Filed: 1989-10-27
Abstract: PURPOSE:To accelerate the operation of a semiconductor memory device such as an EPROM and an EEPROM, etc., by connecting one end of each bit line to the emitter of a bipolar transistor respectively, connecting the base of each bipolar transistor to a constant voltage source and connecting the collector through a resistor to a power source. CONSTITUTION:One end of a bit line BL is connected to the emitter of a bipolar transistor QB1, the base of each bipolar transistor QB1 is connected to a constant voltage source V1 and the collector is connected through a resistor R1 to a power source Vcc. In such a case, all the bit lines BL are set to a prescribed potential by the bipolar transistor QB1 respectively provided in each bit line BL and the bit line BL including a memory cell MC to be read out is selected by a switching means QM1 for bit line selection. Thus, since the potential of the bit line is always set to the prescribed potential, read time can be accelerated even when large parasitic capacity exists in the bit line.

Title: Transmitter/receiver
Inventor: AMIJIMA KAZUHIRO
IPC: H04B10/40
Filed: 1994-11-14
Abstract: PURPOSE: To prolong the service life of a battery as a power source by switching the level of an infrared output corresponding to a distance between a transmission circuit and a reception circuit concerning the transmitter/receiver to perform infrared communication. CONSTITUTION: When the side of the reception circuit is disconnected from the side of a transmission circuit 1, a signal at a low level is outputted from a terminal 4 of an MPU part 3 at the transmission circuit 1, and a PNP transistor Tr 1 is turned on. When a transmitting signal at a high level is outputted from a terminal 5 of the MPU part 3, a field effect transistor(FET) 1 is turned on. At such a time, a current I (V/[(R1.R2)/(R1+R2)]) flows to an infrared LED 1. When the side of the reception circuit is mounted on the side of the transmission circuit 1, the high level is outputted from the terminal 4 of the MPU part 3. Thus, the PNP transistor Tr 1 is turned off. Then, when the FET 1 is turned on, no current flows to a resistor R1 so that a current 1 (V/R2) flows to the infrared LED 1.

Title: Knowledge expression system with priority
Inventor: HARADA MASAHIDE
IPC: G06F15/00
Filed: 1985-12-13
Abstract: PURPOSE:To facilitate the easy designation and alternation of the order when the same types of knowledge are used by providing the priority to each knowledge when the same types of knowledge are used. CONSTITUTION:For instance, a system operator designates a table X as a name to be delivered through an input device 2. Thus a computer 1 searches the knowledge base of a memory device 3. In other words, the knowledges related to input tables A and B are searched and the knowledge (c), for example, is detected and its contents are decoded. Then the priority '1' is known by a priority deciding/reading part 5. Thus the next searching action is carried out based on the knowledge (c). It is known that the table B is obtained from an input table K and a table L and the knowledge about both tables K and L are searched. The contents of these knowledges are decoded and a deciding part 6 decides whether the corresponding table is equal to the input basic data or not. Then one of the information processing procedures is decided to obtain the table X. Thus both the table name and the conversion name are delivered to the operator via a output device 4.

IPC: H01M10/39
Filed: 1988-11-04
Abstract: PURPOSE:To improve the airtightness and the anticorrosive property, to make the manufacture easier, and to realize a low cost, by forming a concave groove at the base of a cathode container to position between an insulator ring and a conductive material for cathode, and to curve to the inner side along the whole periphery. CONSTITUTION:At the base of a cathode container 1, a concave groove 1a is formed to position between an insulator ring 2 and a conductive material M for cathode, and to curve to the inner side along the whole periphery. Since the concave groove 1a with the function to curve to the inner side is formed at the base of the cathode container 1 in such a way, it is not necessary to weld the flexible member to the container. And the formation of the concave groove 1a is not more than a simple process to form squeezing to the inner side. And since the concave groove 1a never projects from the peripheral surface of the cathode container 1, the putting-in and putting-out of the cell to the installing case is easy, and moreover, the movement of the conductive material M for cathode inside the cathode container 1 can be prevented concurrently by the concave groove 1a. Consequently, the airtightness and the anticorrosive property is improved, the manufacture is made easier, and a cost down is realized.
