Patent JP-H0923685-A (JP)
Title: Air conditioner
Inventor: KATO YUJI
IPC: H02P6/12
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent breakdown of a switching element even during the normal rotation at the speed exceeding the control speed by turning off the switching element while the on-duty ratio of the chopping signal is minimized. SOLUTION: When strong wind works on an outdoor fan 7 during the speed control, the on-duty ratio of the PWM signal from a comparison circuit 17 is minimized. A minimum duty ratio detecting circuit 45 detects that the on- period of the chopping signal is equal to the predetermined minimum value and outputs the signal of level H. Thereby, an R-S flipflop 46 is set and the off-command in the level H is applied to a phase distribution circuit 19. In this case, the phase distribution circuit of the upper arm and lower arm forming the phase distribution circuit 19 turns off all switching elements 4 even when the off-command 47 is applied as in the case where the off-command 31 is applied.

Abstract: PURPOSE:To increase the efficiency and the life of a battery by forming a negative electrode of an organic electrolyte secondary battery with a composite prepared by previously absorbing lithium in a molding of carbon fibers having a specific crystallite size. CONSTITUTION:Carbon fibers having a crystallite size (Lc(002)) in X-ray diffraction of 10-170Angstrom  are used. Carbon fibers having a fiber diameter of 0.01-100mum are mixed with a specified amount of binder such as polytetrafluoroethylene, and then formed in a molding having a specified shape. The carbon fiber molding and a metallic lithium are immersed in an organic electrolyte prepared by dissolving, for example, lithium phosphofluoride, propylene carbonate and 1,2-dimethoxyethane, and connected to each electrode of a DC power source to absorb lithium in the carbon fiber molding. A battery using this lithium absorbed carbon fiber molding as a negative electrode has high efficiency and long life.

Title: Original forgetting warning device of copying machine
Inventor: SUZUKI AYUMI
IPC: G03B27/62
Filed: 1984-08-14
Abstract: PURPOSE:To arouse attention of a user or a person of the periphery by sounding a buzzer, when an original is not removed even if a prescribed time elapses after copying has been ended, by combining an original size detecting device and an original forgetting warning device. CONSTITUTION:A buzzer 1 is grounded through a switch 2 by receiving a controlling circuit voltage Vcc of a copying machine. Also, as for a timer 4, one terminal 4a is connected to the switch 2, and other two terminals 4b, 4c receive a copying end signal and an original size signal, respectively, as a start terminal and a reset terminal, respectively. In this state, when copying of an original placed on platen glass is ended, the end signal is inputted to the timer 4 from the terminal 4b, and the timer 4 is started. When a prescribed time elapses as it is, the switch 2 conducts and the buzzer 1 is sounded. If the original is removed from the platen glass in order that it is replaced, a signal from the terminal 4c is stopped, and the timer 4 is reset. Thereafter, even if a new signal is inputted, the timer is not started again unless the copying end signal is inputted again from the terminal 4b.
