IPC: C02F3/12
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To reduce the volume of sludge in a device in which a part of separated sludge is returned to a biological treatment tank by adding alkali to the other part of the separated sludge or sludge pulled out from the biological treatment tank before performing ozone oxidation and returning the ozone oxidized sludge to the biological treatment process.

Title: Return control method for recording head
Inventor: MOMOSE MASANORI
IPC: B41J19/68
Filed: 1981-03-31
Abstract: PURPOSE:To enable shortening of a return time, by a method wherein, in a printer which records a wide figure, in case a recording position is deviated from a real recording range, rhe recording position is renewed to a value equivalent to the real recording for return. CONSTITUTION:When a return indicating data arrives, a CPU first compares a current position XPF of a carriage with a content (home position) SBC of a start resistor. In case the XPF is larger than the SBC, or the carriage is positioned more righward than the home position, it is checked if the carriage reaches a limit position SEC located further rightward. In case the XPF is not larger than the SEC (arrival), there is a possibility for a recording position to shift rightward. Thereby, in that case, decrement is made on a content XC (recording position) of an absolute value count registor so that the XC becomes equal to a+SEC, and the carriage position is caused to be positioned facing and opposite to the recording position to energize the carriage for return. When the CPF is positioned to the start SBC, a return is completed, and the carriage returns to a main flow.

Title: Magnetic recording medium
Inventor: SAIDA MASAHIRO
IPC: C09D5/23
Filed: 1986-03-05
Abstract: PURPOSE:To decrease coefft. of friction and to improve durability and running property by forming a magnetic layer which consists essentially of a tristearyl phosphate and in which a higher fatty acid of 12-19 C and liquid paraffin are incorporated on a substrate. CONSTITUTION:The three materials; tristearyl phosphate, higher fatty acid and liquid paraffin are preferably compounded in a 1-15 parts range with magnetic powder and the range of the compounding ratio thereof is important. The tristearyl phosphate is solid at a room temp. and therefore, the coefft. of friction decreases if the tristearyl phosphate is incorporated into the magnetic layer. The effect thereof is substantially exhibited at the time when the magnetic layer makes sliding contact with the magnetic head. The resonant sound with the magnetic head is then eliminated and the attraction of the magnetic head and the increase of the starting torque are suppressed; in addition, the wear resistance and running property of the magnetic layer are remarkably improved.

Abstract: PURPOSE: To provide high dielectric strength to one of a metal cylindrical high voltage electrode and a grounded electrode by sticking a hollow glass tube to one of  the electrodes with an inorg. adhesive to form a dielectric electrode.  
     CONSTITUTION: Metal cylindrical high voltage electrode 2a is coated with inorg. adhesive 15 and covered with holllow glass tube 2b made of hard glass such as borosilicate glass or soda lime glass, and by heating and pressurizing, tube 2b is stuck to electrode 2a to form a dielectric electrode. Hollow glass tube 1b may be stuck to metal cylindrical grounded electrode 1a with adhesive 15 to form a dielectric electrode.
