Title: Fuel filtering device
Inventor: MAKI NAOKI
IPC: B01D35/14
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To prevent static electricity from being discharged from a fuel filtering device. SOLUTION: Housings 22, 23 of a fuel filtering device 16 are formed of non-conductive resin, and an internal filter 24 is formed of a conductive material. A conductive plug 25 is attached to the housing 22, and the conductive plug 25 and the filter 24 are electrically connected to each other by a spring 26.

Title: Empty driving preventive device for electric hammer drill
Inventor: ITO MASANORI
IPC: B23B45/16
Filed: 1980-09-16
Abstract: PURPOSE: To surely prevent empty driving action of a hammer when a sliding shaft is driven forward by the hammer at the first time after completion of hammering work of an electric hammer drill, by engaging balls urged by resilient member to a ball stopper groove.  
     CONSTITUTION: At the first time when a hammer 9 hits to push out a sliding shaft 10 after the end of hammering work, balls 11, pressed to the internally circumferential side by a resilient member 12, enter a ball stopper groove (b) and are engaged. This engagement can prevent the sliding shaft 10 from coming backward even at upward facing work when weights of a tool holder 13, point end tool 14, ets. are applied to the sliding shaft 10. Since this shaft 10 is stopped (held) in a state of being pushed out to the front, the hammer 9 is not depressed by the sliding shaft 10 and a vent hole (c) in a cylinder 7 is not closed, then air in an air chamber 15 between a piston 8 and the hammer 9 can be circulated through the vent hole (c) to eliminate air spring action, thus the hammering action is not caused.

Title: Method for driving liquid crystal element
Inventor: AOKI KAZUO
IPC: G02F1/133
Filed: 1987-05-26
Abstract: PURPOSE:To prevent the reduction of a contrast rate by impressing voltage pulses more than the saturation voltage of liquid crystal to the liquid crystal at the initial stage of a selection period and then impressing voltage pulses with a reverse and different wave crest value to select ON and OFF of a picture elements. CONSTITUTION:Voltage pulses with -V1, V2 and 0V are successively impressed to a scanning electrode X1 in a selecting period t0 and high frequency AC pulses with + or -V2 are impressed in a non-selection period t1. In the case of turning on a picture element, the voltage pulses with V4, -V4 and the high frequency AC pulses with + or -V4 are successively impressed to a signal electrode Y1. In the case of turning off, the voltage pulses with -V4, V4 and the high frequency AC pulses with + or -V4 are successively impressed. Thereby, the voltage pulses with -V1, -V4, V2+V4 more than the saturation value and the high frequency AC pulses with + or -V4 are successively impressed to the liquid crystal in the ON state. ON the other hand, voltage pulses with -V1+V4 more than the saturation value and V2-V1 less than a threshold value and the high frequency AC pulses with + or -V4 are successively impressed to the liquid crystal in the OFF state. Consequently, the reduction of the contrast rate immediately after selecting ON/OFF and that in the non-selection period can be removed.

Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To prevent the degree of cleanness in indoor air from being reduced, and to suppress discomfort caused by blowing off cold wind on defrost by operating the defrost during heating operation with the amount of blast for maintaining the degree of cleanness of air in a room to be air-conditioned. SOLUTION: A blower does not stop during defrost operation, and the amount of blast is changed to that being shown in a figure. On defrost operation during heating operation, the blower is continuously operated by the amount of blast Vt without stopping, thus preventing the target degree of cleanness in an air- conditioning room from being reduced, and at the same time suppressing discomfort caused by blowing off cold wind. The amount of blast Vt is the minimum value for maintaining the target degree of cleanness in the air-conditioning room.  The minimum amount of blast Vt for securing a target degree of cleanness Ct is determined in the defrost operation, and the blower is controlled so that the blower is operated by the amount of blast Vt on defrost, thus preventing the degree of cleanness in the air-conditioning room from being reduced on defrost, and at the same time avoiding the discomfort caused by blowing off cold wind.
