Title: Automatic paper feeding device
Inventor: SASAKI MARIKO
IPC: B65H1/04
Filed: 1986-11-04
Abstract: PURPOSE:To make it possible to prevent an oblique sheet feeding or a sheet clogging, by moving a pair of original guides furnishing with plural sensors to detect the contact to an original, symmetrically to the center line of an original table. CONSTITUTION:When an original 11 is loaded on an original table 12, a motor 17 is rotated to move original guides 14 and 14 to the center line side of the original table 12, and the original guides 14 and 14 hold the both ends of the original 11 in the condition vertical to a sheet feeding roller 13, while setting the original at the central position of the original table 12. In this case, although a pressure sensor 18 responding to the angles 11a and 11b of the original 11, of the plural pressure sensors 18 installed at the original guides 14 and 14, is contacted to the original, the motor 17 continues to rotate, but when at least two or more pressure sensors of them are contacted to the original, the motor stops. Then a conveyer roller 20 is rotated by a motor 21, and the original 11 is delivered to the sheet feeding rollers 13. In such a way, an accurate automatic paper feeding can be carried out, and an oblique paper feeding or a paper clogging can be prevented.

Title: Lens driving mechanism for zone focus camera
Inventor: MAEDA HIROSUKE
IPC: G03B3/10
Filed: 1990-09-28
Abstract: PURPOSE:To adapt the camera to zone focusing >=3 zones by selecting one of solenoids to operate a swaying lever and positioning it at plural positions and a position where all the solenoids are released. CONSTITUTION:When a voltage is applied to a solenoid 12 while a lens group 1a is set at the 1st position which is the most rear end with the energizing force of a spring 5, an extension lever 9 rotates around a shaft 10 as shown by an arrow A and the moving lens group 1a moves to a 2nd position. When a voltage is applied to only a solenoid 11 while no voltage is applied to the solenoid 12, the angular range of the swining of the extension lever 9 around the shaft 10 is smaller than that when the voltage is applied to the solenoid 12 and the lens group 1a moves to a 3rd position between the 1st position and 2nd position. Consequently, the moving lens group 1a moves to the positions corresponding to three zones to set the position of a photographic lens.

Title: Closed type motor-driven compressor
Inventor: UMEOKA IKUTOMO
IPC: F04B39/00
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To improve intake efficiency of refrigerant into a cylinder block and improve muffling effect of an intake muffler by composing the intake muffler of a conical front cone and an inverted conical rear cone. SOLUTION: A reed valve 15 repeats opening-closing action several times at the time of an intake stroke so as to generate pressure wave near an intake hole 14. This pressure wave travels as sound wave toward a muffler inlet part, and is amplified by the conical taper of a front cone 18 and reflected toward a muffler outlet part by the inverted conical taper of a rear cone 19. The reflected pressure wave reaches the muffler outlet so as to accelerate intake of refrigerant into a cylinder block, which results in improving intake efficiency. Since most of pressure wave is reflected by the rear cone 19, sound wave radiated from the muffler inlet part can be reduced so as to improve muffling effect.

Title: Control driver for motor-driven compressor
Inventor: YOSHIDA MAKOTO
IPC: H02P27/06
Filed: 1993-10-22
Abstract: PURPOSE:To prevent stop of a motor-driven compressor due to fluctuation in a power source by increasing a frequency increasing speed or a voltage rising speed of an inverter larger than a high number of revolutions in a low number-of-revolution range of a variable number-of-revolution range. CONSTITUTION:An air conditioning controller 5 decided number of revolution of a compressor 1 based on signals from various sensors 6 and a room temperature setter 7, and outputs it to an inverter 4. A controller 11 in the inverter 4 so converts a DC voltage to a variable frequency or variable voltage AC voltage by switching element group 8 as to normally drive the compressor 1 by this set number of revolutions. It increases a frequency increasing speed or a voltage rising speed of the inverter 4 to larger than a high number-of- revolutions in a low number-of-revolution range of a variable number-of- revolution range. Thus, discharge of lubricating oil of the compressor into a refrigerating cycle can be suppressed in the high number-of-revolutions range, and a decrease in a diffused air temperature of an air conditioning transient period, a rising speed can be accelerated in the low number-of-revolution range.
