Title: Purifier using methane bacteria
Inventor: MAEKAWA TAKAAKI
IPC: C02F3/34
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To keep a high org. matter decomposing capacity without need for the heating by an external heat source by composing the purifier of an acid fermentation tank and a methane fermentation tank and connecting the acid fermentation tank to an aerobic reaction tank through a pump connected to a feed pump. SOLUTION: This purifier is composed of an aerobic reaction tank 100 and a two-phase fermentation tank 101 placed in the aerobic reaction tank 100. A photosynthetic bacteria carrier 102 immobilizing photosynthetic bacteria is disposed at the bottom of the aerobic reaction tank 100, and a blower 103 for sending air into the aerobic reaction tank is attached to the inner wall or outer wall of the aerobic reaction tank 100. The aerobic reaction tank 100 is produced by the use of an insulating material when used in a cold district. The org. matter in sewage is partially decomposed by the photosynthetic bacteria, and the lower fatty acids such as acetic acid are oxidized by the bacteria. As a result, the heating by an external heat source is not needed, and a methane-bacteria purifier maintaining a high org. matter decomposing capacity is obtained.

Title: Control method of electric rolling stock
Inventor: NODA TOMOHITO
IPC: H02P7/00
Filed: 1990-07-27
Abstract: PURPOSE:To improve operating efficiency by making the ratio of output voltage to output frequency larger than a fixed value determined by acceleration when an electric rolling stock made to travel by a linear induction motor is made to power-run by an output from an inverter. CONSTITUTION:The linear induction motor of an electric rolling stock is partitioned into modes I-IV and driven by variable voltage VM and variable frequency finv output from an inverter. Voltage VM is raised for a fixed time at the mode I, and voltage VM and frequency finv are increased simultaneously at the mode II while the ratio of voltage to frequency is made larger than the ratio of VM/finv determined by acceleration in at least one part (thrice in the graph). Voltage VM is kept constant, frequency finv is increased and slip frequency FS is elevated, and torque T is held constant at the mode III. Voltage VM and slip frequency FS are kept fixed, frequency finv is augmented and torque T is reduced at the mode IV. Accordingly, operating efficiency is improved.

IPC: B41J29/48
Filed: 1985-09-10
Abstract: PURPOSE:To detect the presence of a paper sheet and transmit information concerning the function of change-over to a printer body, by providing an actuator for actuating an MLD switch on the printer body when a detecting arm and a change-over arm is operated. CONSTITUTION:An MLD detection arm 3 is adapted to be lowered at its roller section 13 side by its dead weight, and therefore, it lowers so that the roller section 13 falls onto a cutout 2a formed in a hopper 2 when no paper sheet is set on the hopper 2. Accordingly, a hook section 14 lifts up an actuator 10. As a result, no paper sheet is detected. When the change-over switch 1 is turned into the AUTO side, a stud 8 on a change-over switch arm 6 is pushed down by means of a cam surface 1b, and therefore, the actuator 10 actuates an MLD switch 12 only by means of the MLD detecting arm 3 since a hook section 9 is retracted downward.
