Title: Storage battery charging circuit
Inventor: INOUE KOICHI
IPC: H02J7/00
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To perform charging in high safety with a simple circuit without using a contact switch by providing a constant-current source wherein the positive electrode is grounded with respect to a charging current, the current is made to flow all the time without problems and the specified minute constant current is made to flow out. SOLUTION: A switch circuit SW1 is inserted between a charging-current feeding circuit 8 and a contact terminal 7a and in the OFF state at the normal time. The switch is turned ON when the signal is received from an AND gate 9c. Thus, a battery 3 and a battery charging circuit 10 are directly connected through the contact terminals 7a and 7b under the state wherein the battery is mounted. Therefore, the minute current flows at first from a power supply line +Vcc to the battery 3 through a minute constant-current source 7. As the current of the minute constant-current source 7, the constant current of several μA, which is smaller than 1/1,000 of the current of several-hundred-mA unit of the charging-current feeding circuit 8, to about 0. several μA smaller than several μA are made to flow out.

Title: Purification of tertiary amine
Inventor: SATOU HARUYO
IPC: C07C209/28
Filed: 1979-04-26
Abstract: PURPOSE: To purify a tertiary amine and, in some cases, improve its yield, by heating formaldehyde (derivatives) remaining in the tertiary amine in a specific temperature range under acidic conditions.  
     CONSTITUTION: A tertiary amine is obtained by the reductive methylation of a primary or secondary amine with formaldehyde and formic acid or formaldehyde and hydrogen. On this occasion, the tertiary amine is purified by heating formaldehyde and/or formaldehyde derivatives remaining in the tertiary amine to 80W150°C under acidic conditions. The acid is preferably formic acid and the pH is adjusted below 6.5. When the desired tertiary amine has functional groups, its yield can be improved, by this process.

The printer shifts a mode to a preservation mode after the reception of the REC instruction, operates an input side switch SW1, inputs printing data to a memory 13 and preserves it. When a STOP instruction is received, a normal mode is recovered from the preservation mode. Then, the mode is shifted to a reproduction mode after the printer receives the PLAY instruction, the input side switch SW1 and an output side switch SW2 are operated, printing data preserved in the memory 13 is reproduced and the designated number of copies are printed. Thus, copy printing is easily executed without repeatedly transmitting the same data.

IPC: H04N9/16
Filed: 1984-03-19
Abstract: PURPOSE:To obtain color pictures by giving the brightness/darkness of light emission and the luminous light emission corresponding to R, G and B to a scan line, i.e., a light emitting system in order to transmit the color pictures by a gun and a beam. CONSTITUTION:A color signal is divided into three parts and then put on the scan lines corresponding to R, G and B of a screen by switching elements, etc. Thus a color picture is produced through a light emission system. Therefore it is required to change the order of R, G and B of the signal to be transmitted in accordance with the forms of R, G and B of the screen. This change of order is carried out assuredly by using the R, G and B signals as digital signals when color signals are put on the scan line. In addition, the transmitted R, G and B signals are also digitized to obtain the sharp brightness/darkness of light emission and luminous light emission.
