Title: Semiconductor integrated circuit
Inventor: TAKASE HIROSHI
IPC: H01L27/092
Filed: 1990-04-20
Abstract: PURPOSE:To prevent a leakage current in an I/O unit by providing an N-channel type transistor in which a gate is connected to a high potential side power line, a drain is connected to the other of source and drain of a driving MOS transistor, and a back gate is connected to a low potential side power line. CONSTITUTION:A positive voltage is not transmitted to the drain 24 of a P- channel MOS transistor 28. Accordingly, the MOS transistor 28 of an 'H' level driving output is separated from an output terminal 20, and no leakage current flows to a P-N junction between the drain 24 and a substrate 21. Since a back gate 36 is connected to a ground VSS even in the transistor 34, a P-N junction between a source 31 and a well 29, and a P-N junction between the well 29 and the substrate 21 are reversely biased. Accordingly, no leakage current flows even through these P-N junctions.

Filed: 1980-08-05
Abstract: PURPOSE:To avoid a reduction of the processing speed, by comparing an address of the next refresh with a normal address given an access from a central processing unit during a constant period immediately before said address and then inhibiting the refresh in case when a coincidence is obtained from the comparison. CONSTITUTION:The output signal of the 2nd refresh address counter 10 that shows the next refresh address is compared with a normal address given from an address receiving circuit in an address comparator 11 during the working of the normal access given from a CPU1.

Title: Optical lan system and abnormality detection method
Inventor: MOTOMITSU KAZUO
IPC: H04B10/27
Filed: 1992-04-24
Abstract: PURPOSE:To transfer only an abnormal station to off-line by writing information representing an abnormality to a part in a transmission signal frame corresponding to a relevant controller when each controller discriminates occurrence of the abnormality from a signal from other controller so as to prevent stations other than the abnormal station from being escaped from the optical LAN when a station whose optical transmission level is decreased below the specified range. CONSTITUTION:A slot used to write an error bit corresponding to each of control and protection devices is provided in an error bit status part provided at a data in a signal frame. A station 32 detecting it that an output level from a station 31 is in error writes and outputs an error bit 1 to a slot of a number 31 of an error bit status part in a signal frame outputted from the station 32. The abnormal station 31 receiving the signal frame detects it that an optical signal level outputted from the station 31 is decreased by checking whether or not '1' is written in the slot of the number 31 of the error bit status part.

Title: Thermal recorder
Inventor: ISHII SHIGENORI
IPC: B41J2/32
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To suppress relative bias in the longitudinal direction between a thermal head bar and a platen roller surely by mounting the thermal head bar at a central position in the longitudinal direction thereof through a micro play with respect to the other of a housing body and a cover body. SOLUTION: When a cover body 34 is brought close to close position from open position, a pair of radial cams 60 on the platen roller 10 side can be engaged easily and lightly with a pair of forks 62 on the thermal head bar 12 side because the thermal head bar 12 is mounted on the cover body 34 through a micro play. The action for matching the thermal head bar 12 correctly with the platen roller 10 in the radial direction can be regulated automatically by finally sliding the supporting lug part 24 of a supporting bar 22 appropriately relative to a supporting pin 30 through a bearing hole. Furthermore, the radial cam 60 and the fork 62 are engaged smoothly in the process for pressing the thermal head bar 12 against the platen roller 10.

Title: Method of charging raw material to blast furnace
Inventor: INADA TAKANOBU
IPC: C21B5/00
Filed: 1988-04-27
Abstract: PURPOSE:To enable the adequate control of the grain size distribution of the raw material in the radial direction in a furnace and to avert the degradation in the controllability of the weight ratio distribution of ore and coke in a movable armor by separating raw materials in which fine grains and coarse grains coexist and intermediate grain size raw materials which do not belong to these materials and charging the materials separately into the furnace. CONSTITUTION:The charging raw materials are divided to the intermediate grain size raw materials between the fine grains and the coarse grains and the raw materials in which the fine grains and coarse grains coexist. The divided materials are charged into the furnace. The intermediate grain size raw materials are charged first into the furnace and in succession, the raw materials in which the fine grains and coarse grains coexist are charged therein at the time of the charging. The segregation of the fine materials in the raw materials to the furnace wall part is thereby intensified and the degradation in the air permeability by the fine grains is lessened. The controllability of the raw material grain size distribution in the radial direction of the furnace and the weight ratio distribution of the ore and the coke are thus improved and, therefore, the blast furnace condition is stabilized.

This data is added to the data from a circuit 22 with an addition circuit 25 to update data.

Abstract: PURPOSE:To enable production of a calcined thin or thick molded body having high light transmittance with hardly any pores, by specifying a method for forming and an organic binder in producing a light-transmitting calcined molded body of composition (PLZT) in which lead in lead titanate zirconate is partially substituted by La. CONSTITUTION:Raw material powder for PLZT is kneaded with an organic binder consisting of a mixture of wax with a thermoplastic resin and, as necessary, a plasticizer and lubricant. Furthermore, an organic solvent capable of dissolving the above-mentioned substances, as necessary, is added and mixed in a ball mill, etc., to peptize aggregated particles. The resultant mixture is then filtered to remove foreign materials to carry out concentrating, drying and kneading. The obtained molding compound is subsequently injection molded into a molded body of a prescribed shape. The resultant molded body is then calcined in an oxygen stream at 1000-1300 deg.C. The raw material powder can be homogeneously dispersed and kneaded and fluidity in the injection molding can be improved by the above-mentioned method to afford a dense and homogeneous molded body. Thereby, the aimed calcined molded body excellent in light transmitting properties with hardly any pores after calcining is obtained.

Filed: 1989-04-28
Abstract: PURPOSE:To interconnect plural terminal equipments to be driven by placing a gate circuit to a pre-stage of a terminal equipment and limiting its format to be that in matching with its terminal equipment only. CONSTITUTION:A gate circuit 10 is provided between an interface 8 of a hand- free adaptor 2 and a 2nd telephone set 4. A gate signal S1 is fed to the gate circuit 10, which inhibits signal passing while a display signal DATA 1 is sent and allows the passing of a serial signal DATA 2 sent when no gate signal S1 is outputted and the signal DATA 2 is sent to the 2nd telephone set 4. Since the serial signal DATA 2 is a signal subjected to the interface, the interfacing to the 2nd telephone set 4 being a terminal equipment is ensured by the signal processing. Thus, plural terminal equipments driven by a control signal with a different format are interconnected.
