Title: Lead storage battery
Inventor: KAWANAMI YOSHIHARU
IPC: H01M10/10
Filed: 1978-07-14
Abstract: PURPOSE: To prevent shortage of a lead storage battery due to the decrease in electrolytic concentration at excessive power dissipation of the battery by adding sulfate dissolved in dilute sulfuric acid without harm to the electrolyte in the battery limiting the electrolyte amount.  
     CONSTITUTION: To the electrolyte limited to less than 1.2ml per 1g of anode active substance in a lead storage battery is added sulfate such as, for example, soda sulfate, potassium sulfate or the like dissolved in dilute sulfuric acid without harm for the battery. Since sulfuric ion is retained in the electrolyte even after the electrolyte concentration is lowered at the end of power dissipation of the battery, the lead sulfate is not dissolved in the electrolyte to thereby prevent shortage of the battery.

IPC: H01L21/3205
Filed: 1992-04-08
Abstract: PURPOSE:To form sheet resistances of interconnections having different specific resistances which are generated due to a difference of impurity implanting conditions. CONSTITUTION:Polysilicon 16 (about 3800Angstrom ) is formed as an interconnection layer on a semiconductor substrate 11, and N-type impurity is implanted in the polysilicon 16 by ion implanting phosphorus. Thereafter, the polysilicon 16 is reduced in thickness to about 3000Angstrom  only on an N-channel side polysilicon interconnection formed part. N-channel and P-channel side interconnections 16-(N) and 16-(P) are formed from the polysilicon 16. N-type and P-type impurities are implanted in order to form N-channel and P-channel side source/drain regions 20 and 21. Specific resistances of the interconnections 16 (N) and 16-(P) become different due to a difference of the impurity implanting conditions, but since the thicknesses of the films are altered, sheet resistances can be equalized.

Abstract: PURPOSE:To rationalize supply of works to plural working robots in the stage of transferring plural works from a single conveying line to said robots by selecting discretely and performing the conveyance and transfer in accordance with the conveying and working conditions. CONSTITUTION:Conveying bases 9a- are provided on a single free flow conveyor 1 and are fed at a constant speed from a position 2 for loading works to stations 3a- and an unloading position 4. The transfer of the works to plural welding robots 5a- is accomplished by articulated robots 6a-. The work conveying condition on the conveyor 1 and the operation progressing condition of the robots 5a- are discriminated by a selecting means 7 which in turn selects the stations 3a- to stop conveying the works and the robots 6a- to be operated and stops temporarily only the bases 9a- corresponding thereto, thereby completing the operation. The smooth transfer of the works to the robots is thus made possible irrespectively of the forward and backward works and the working condition.

Abstract: PURPOSE:To enable high fixing quality to be obtained, even if a deposited amount of unfixed toner on a transfer material fluctuates. CONSTITUTION:A signal from a sensor 22 regarding the detected amount of toner deposition is inputted, together with a signal from a thermister 34, to CPU 23 via A/D converters 26 and 27, and an I/O port 28, and compared with data preliminarily stored in ROM 24 and RAM 25.

According to this construction, if a toner deposition amount is excessive in such a case as in forming a color image, the temperature of the fixing roller 31 can be raised to apply sufficient heat to the toner and obtain high fixing quality.

Title: Voice suppressing method for transmission device

IPC: H04M7/00
Filed: 1991-04-19
Abstract: PURPOSE:To attain the effective application of an exclusive line by switching a band compressing transmission state to a facsimile relaying transmission state when a call is started and resetting the band compressing transmission state when the transmission is complete. CONSTITUTION:The connection of a reception signaling (SR) state is recognized 118 through a device A 104, and a voice compressing state is switched 112 to a facsimile relaying transmission state when the sending signaling (SS) and the signaling (SR) are set in the connection states. At the same time, the SR is sent to a public network 102 via a switchboard PBX 103. Thus a call is secured between a facsimile terminal 101 of the transmission side and a facsimile terminal 108 of the reception side. In a call end processing state 130, the terminal 101 cut 131 a line and the corresponding SS is broken 132. Thus the device 104 recognizes this state and reswitches 134 the voice compressing transmission state to reset this transmission mode. Thus it is possible to deal with the connection to such countries where the voice compression inhibiting rules are valid.

Title: Method and device for measuring magnetic field
Inventor: BUORUFUGANGU KURATSUTSUAA
IPC: G01R33/04
Filed: 1982-05-26
Abstract: In order to measure a magnetic field, an exciting current rising in small increments is applied to a measuring probe so that the coil of the probe traverses the entire range from the negative saturation up to the positive saturation. At the secondary side, respective voltage pulses which decay according to an e-function are measured at the coil. The time constant of the voltage pulses corresponds to the respective coil inductance. Since the coil inductance is shifted relative to the zero point of the exciting current due to an external magnitude field, more voltage pulses with a high time constant are produced on one side of the zero point than on the other side. By means of digital counting of all voltage pulses whose time constant exceeds a minimum value both given a negative exciting voltage as well as given a positive exciting voltage, one obtains two measured values whose difference directly produces a measured value for a strength of the external magnetic field.
