Title: Voltage control circuit
Inventor: KURODA TADASHI
IPC: G05F1/67
Filed: 1984-10-25
Abstract: PURPOSE:To incorporate parts as much as possible within an LSI ship to attain the miniaturization and cost reduction of a device, by combining two diodes provided in the LSI ship to obtain the characteristics equal to an external LED. CONSTITUTION:When the output voltage VS of a solar battery 2 is smaller than the forward conduction start voltage VF1 of a diode 6, the voltage V2 supplied to an LSI1 is defined as V2 VS since the input impedance of the LSI1 is extremely high. Then the forward current I3 flows to the diode 6 when the VS exceeds the VF. while the forward current I4 flows when the VS exceeds the voltage VF2 higher than the VF1 since a resistance 8 is connected in series to a diode 7. Therefore the output current I5 of the battery 2 is defined as I5=I3+I4. The characteristics of the I5 are about equal to a characteristic curve of a conventional external LED. That is, a sudden rise of about 1-100muA is shown with the voltage of about 1.5V. Thus it is possible to keep the voltage V2 at the optimum level of about 1.5V.
Patent JP-H1069922-A (JP)
Title: Non-aqueous electrolyte lithium secondary battery
Inventor: KOSHIBA NOBUHARU
IPC: H01M4/48
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To improve required excessive charge and discharge resistance characteristics by rendering an electric capacity of a negative electrode less than an electric capacity in a chargeable and dischargeable area of a positive electrode. SOLUTION: A spinel type lithium titanium oxide has its stable characteristics in a wide range of a potential area, therefore, an electric capacity of the negative electrode is less than that in a reversible area of the positive electrode. Thus, the positive electrode potential is not greatly changed even at a discharge end of a battery, is stayed in the reversible area, and is constantly maintained without causing crystal destruction. On the other hand, the negative electrode potential is close to the positive electrode potential, however, even if the positive electrode potential is a high potential of 3 to 4V, the negative electrode is not destroyed and is stable, therefore, it can withstand excessive discharge. Further, since the negative electric capacity is smaller than the positive electrode during charging, the positive electrode potential is not changed, the negative potential falls, and charging completes. Since the negative electrode maintains a stable state at a potential of 0V, the over-charging permissible upper limit voltage of the voltage can be 1.5V higher than the flat voltage during charging, and reliability of withstand over-charging can be improved.

Title: Method of maintaining oil seal function gear motor
Inventor: CHIHARA YUKIO
IPC: F16H57/04
Filed: 1994-09-20
Abstract: PURPOSE:To improve life of an oil seal by holding cooling and lubrication oil in a space part formed to a speed reducer side rather than the oil seal between a partition member and a rotational shaft and forming an oil film between the oil seal and a collar fit to the rotary shaft and cooling both of the oil seal and the collar by the oil film. CONSTITUTION:A space part 22 is formed at a reduction device side 2 rather than an oil seal 19 between a partition member 3 and a rotary shaft 4. Cooling and lubricating oil 21 is held in this space part, 21. An oil film is formed by this cooling and lubricating oil 21 between the oil seal 19 and a collar fit to the rotary shaft 4 and the oil seal 19 and the collar 20 are cooled. Lubricating function of the oil seal 19 with the collar 20 can be kept agreeably by the cooling and lubricating oil 21. The cooling and lubricating oil 21 has higher viscosity than lube oil and thereby, if lube oil 21 is lubricated in a position corresponding to the space part, 22 of the collar 20, assembling work of parts can be performed smoothly. Thereby, heat by rotation of the collar 20 is cooled and lubricated by the oil film of the cooling and lubricating oil 21. Accordingly, deterioration of the oil seal 19 can be prevented.

Title: Photometric instrument
Inventor: KANAZAWA HAJIME
IPC: G01J1/44
Filed: 1986-09-25
Abstract: PURPOSE:To take a high-accuracy measurement in a wide illuminance area by selecting the 1st holding means in an illuminance area where a peak value from a current-voltage converting means is linear to variation in illuminance and the 2nd holding means in other areas where a stable value is linear to the illuminance variation. CONSTITUTION:The peak value of the signal from the current-voltage converting means consisting of a lograrithmic compressing diode LDA and an operational amplifier is held by the peak holding circuit PH of the 1st holding means. Further, the stable value which is a specific time delayed behind the peak value of the signal from the current-voltage converting means is held by the 2nd holding means consisting of a sample holding circuit SH and a delay circuit DL. Then the output of the 1st holding means is selected in the illuminance area where the peak value has excellent linearity to the variation in illuminance and the 2nd holding means is selected in other illuminance area where the stable value has excellent linearity to the variation in illuminance. Consequently, a signal used basically for photometric information calculation has good linearity to the illuminance variation over the entire illuminance area and the measurement accuracy is improved.

When the support arms 2 and 3 ascend to such a level as equal to or above the prescribed angle for opening the door 1, the pin 16 is disengaged from the recessed section 15 of the holder 14. Also, when the arms 2 and 3 descend to such a level as equal to the prescribed angle for closing the door, the pin 16 comes to be engaged with the recessed section 15 of the turning holder 14. Thus, the forward end of the door 1 smoothly moves vertically without protruding externally.

Title: Mobile communication system, exchange used for the system and method for controlling synchronization between base stations
Inventor: SHISHINO SHINICHI
IPC: H04W56/00
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To attain synchronization between base stations with excellent stability at a reduced cost in a mobile communication system. SOLUTION: A single synchronizing signal generator 15 and a plurality of radio base stations 2-1-2-n are interconnected receptively by channels wherein a synchronizing signal is delivered to the radio base stations 2-1-2-n via the channels. Thus, there is no need for exclusive circuits such as a multiplexer circuit and a multiplexer/demultiplexer circuit, and the synchronizing signal is transmitted to each radio base station through a standard speech communication IF. Thus, the synchronization between the base stations is attained at reduced cost with excellent stability.

Filed: 1993-08-18
Abstract: PURPOSE:To carry out the filling work with simple operation without empolying any device for evacuating a vessel by a method wherein anhidride of inorganic heat accumulating agent is produced by heating the inorganic heat accumulating agent consisting of an inorganic salt having water of crystallization to fill a vessel with it and, thereafter, water of equivalent amount is added to return the same to the inorganic salt having water of crystallization. CONSTITUTION:Water of crystallization, retained by inorganic heat accumulating agent 3 for filling a vessel 1 with it through a filling port 10, is separated by heating and dehydrating process to obtain smooth powder having high fluidity, then, the vessel 1 is filled with the powder through the filling port 10 and when a specified filling is finished, an equivalent amount of purified water is added to return the agent to the original salt. The dehydration of the inorganic heat accumulating agent 3 having water of crystallization can be effected uniformly and quickly by heating the agent through the application of microwaves. The volume of the inorganic heat accumulating agent 3 is reduced remarkably by dehydration whereby a space, formed in the vessel 1, can be filled simply with the amount of substantially 100% of the inorganic heat accumulating agent.

Abstract: PURPOSE:To prevent a tone detection circuit from malfunctioning by inserting a circuit frequency-dividing a frequency of a voice detection signal into one over an integral number between a voice detection output side at the reception side and a filter in an advertisement use loudspeaker. CONSTITUTION:A voice signal from an input terminal 1 is inputted to a speaker 3 via an amplifier circuit 2 and also to a 1/n frequency division circuit 4.
