Title: Developer for electrophotography
Inventor: MURAKAMI SATORU
IPC: G03G9/107
Filed: 1988-11-25
Abstract: PURPOSE:To obtain the developer for electrophotography having an excellent gradation characteristic and resolving power by incorporating a specific toner and ferrite carrier into the developer, thereby decreasing splashing of the toner and the contamination in the machine, averting the increase in fogging by continuous copying and reducing the toner consumption. CONSTITUTION:This developer contains the toner contg. a carbon black A having 650 to 830m<2>/g specific surface area by a BET method and 300 to 500ml/100g DBP oil absorption and a carbon black B having 100 to 250m<2>/g specific surface area by a BET method and 50 to 130ml/100g DBP oil absorption in a 20/80 to 80/20 range by the weight ratio of B/A and the ferrite carrier. The toner splashing and the contamination in the machine are critically decreased in this way and the generation of fogging is lessened in spite of continuous copying. The toner consumption is thus reduced and the gradation characteristic and resolving power are improved. The satd. image density is lowered, the toner consumption is reduced and the gradation characteristic is improved in comparison with the case in which only the carbon black A is used.

IPC: H03G3/00
Filed: 1987-11-30
Abstract: PURPOSE:To listen to a voice/music at a small sound volume at sleeping and at a large sound volume at awaking by suppressing the sound volume from the attenuation start time till the power supply interruption time and restoring the sound volume to the original sound volume at application of power. CONSTITUTION:The user gives a power-off time data, a power-on time data and a sleeping continuity time data to a timer 5. The timer 5 counts the time and the attenuator 3 starts sleeping operation at the arrival of the sleeping start time. Thus, the level of an audio signal 10 outputted to a speaker 4 is decreased gradually. When the timer 5 reaches the power on time, a power supply section 9 turns on the power to an audio signal source 1, etc. Since the sleep operation signal 6 is not outputted, the attenuator 3 outputs the audio signal 10 at its own level.

Title: In-cylinder injection type two-cycle internal combustion engine
Inventor: KOBAYASHI TATSUO
IPC: F02B25/16
Filed: 1990-11-07
Abstract: PURPOSE:To obtain a good ignition and a good combustion with a high air utilization rate by carrying out the first round injections, before and after an exhaust valve is closed, from the first fuel injection valve, in a medium load operation of an engine, and after that, carrying out the second round injections from the second fuel injection valve to the inside of a recessed groove formed on the top surface of a piston. CONSTITUTION:In a medium load operation of an engine, the first round fuel injections are carried out from the first fuel injection valve 14a before and after an exhaust valve 7 is closed. As a result, the injection fuel is prevented from blowing out in an exhaust port 13 through the exhaust valve 7. And the injection fuel from the first fuel injection valve 14a makes a large diffusion force by expanding the spraying angle, and the injection fuel is hit along a wide area on the top surface of a piston 2. Then, the second round fuel injection is started from the second fuel injection valve 14b. As a result, the injection fuel is hit on the recessed internal wall surface of a recessed groove 15 in a specific angle. Consequently, not only a mixture gas to ignite in a good condition around an ignition plug 10 can be formed, but also a good combustion mixing the injection fuel and the air sufficiently and generating no smoke can be obtained.
