Title: Ac generator for vehicle
Inventor: KUSASE ARATA
IPC: H02K19/36
Filed: 1983-04-25
Abstract: PURPOSE:To improve the output of an AC generator for a vehicle by providing 3-phase armature windings and exciting coil wound concentrically at pi radian pitch of an electric angle and an auxiliary winding wound concentrically at pi/3 radian pitch of an electric angle. CONSTITUTION:When an auxiliary winding 3 generates an electromotive force so that the left side becomes a negative polarity and the right side becomes a positive polarity, the force is applied to a B terminal 10 in a passage from the left of an exciting coil 5 of ground potential, a diode 8b, the winding 3 and a diode 7b to supply a current to the coil 5. When the winding 3 generates the force so that the left side becomes a positive polarity and the right side becomes a negative polarity, a current is supplied to the coil 5 in a passage from the ground, the diode 7b, the winding 3 and the diode 8a. An AC electromotive force generated at the neutral point 0 of armature windings 2x-2z supplies a DC current to the B terminal 10 through the diodes 7a, 7b, and a current is supplied to the coil 5. In this manner, the output of approx. 8% is improved in an AC generator for a vehicle of 90A class.

Filed: 1986-03-31
Abstract: PURPOSE:To form a drum shaft with soft materials and make bearings of the drum shaft unnecessary by connecting the first hard leaf spring to the drum shaft through the second soft leaf spring. CONSTITUTION:Drum flanges 12 arranged in both end parts of a photosensitive drum 11 are pierced by a drum shaft 13 and are supported freely rotatably. A hard leaf spring 14 as the first conductive member is fixed to the inside face of each drum flange 12 by welding. Plural first claw parts 15 are formed on the outside peripheral part of the leaf spring 14 and are pressed to the inside face of the photosensitive drum 11. The second claw parts 16 are formed on the flat spring 14 also. A soft leaf spring 17 as the second conductive member is provided between each drum flange 12 and the leaf spring 14, and a tongue piece 18 is formed in the center part of the leaf spring 17. The tongue piece 18 is pushed by the claw part 16 of the leaf spring 14 and is brought into contact with the peripheral surface of the drum shaft 13. Since the soft leaf spring 17 is brought into contact with the drum shaft 13 in this manner, it is unnecessary to make the drum shaft hard.

Title: Electrifying method and device, image forming device and process cartridge
Inventor: ISHIYAMA HARUMI
IPC: G03G15/02
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain direct injection type electrification excellent in the uniformity of electrification and stable over a long period, even if a simple member such as an electrifying roller is used as a contact-electrifying member by interposing conductive grains in the nip part between an electrifying member and a body to be electrified. SOLUTION: In an electrifying nip part (n) being the nip part between a photoreceptor 1 as the body to be electrified and the electrifying roller 2 as the contact-electrifying member, the contact-electrification of the photoreceptor 1 is attained in a coating state with electrification accelerating grains 3. Thus, in the electrifying nip part (n), the electrifying roller 2 can come into contact with the photoreceptor 1 which having a difference between their speeds. Moreover, the electrifying roller 2 comes into close contact with the photoreceptor 1 with the electrification accelerating grains 3, that is, the grains 3 existing in the electrifying nip part (n) being the nip part between the roller 2 and the photoreceptor 1 rub the surface of the photoreceptor, without a gap, to directly inject en electric charge into the photoreceptor 1. Therefore, high electrifying efficiency which can not be obtained by conventional roller electrification can be obtained and a voltage almost equal to that applied to the electrifying roller can be applied to the photoreceptor 1.

Title: Electronic hemadynamometer
Inventor: OZAWA HITOSHI
IPC: A61B5/022
Filed: 1990-03-23
Abstract: PURPOSE:To accurately make an original judgement on blood pressure only based on the Korotkoff sound signals by providing a second recognition means which becomes active only when gate signals are energized, and recognizes the existence of the Korotkoff sound based on detected signals. CONSTITUTION:The time of 2 seconds is equally divided by 16 so that the noise level in each window which is set up to 125ms, is measured. The peak and bottom levels in each window are detected so that they are stored in a peak register KP and a bottom register KB, respectively, and furthermore, each difference is determined so that it is made to be the noise level in each window. Upon completion of interruption process for K sound sampling, KSINT is disabled so that it is judged whether or not an inequation of the difference is not less than THK. If the answer is 'YES', after flag 2ndF is examined, and when the following Korotkoff sound is detected, it is examined whether or not an inequation of t>=0.3S exists, an erroneous judgement based on noise is thereby prevented with K sound signals neglected in this range. By this constitution, the mixing of counterfeit Korotkoff sound signals can be prevented while an accurate judgement can be made only based on the Korotkoff sound signals.

Title: Method for regenerating fibrous activated carbon
Inventor: OTSUKA KIYOTO
IPC: C01B31/08
Filed: 1991-03-12
Abstract: PURPOSE:To efficiently adsorb and remove trace chloroform in city water with a simple method by desorbing the chloroform adsorbed on fibrous activated carbon with hot water. CONSTITUTION:The chloroform adsorbed on fibrous activated carbon is desorbed with hot water at >=60 deg.C to regenerate the activated carbon. The chloroform is adsorbed on the activated carbon and easily desorbed with hot water, because there are no macropores and transitional pores in the activated carbon and the surface area of the activated carbon is far larger than that of the granular activated carbon. Since chloroform is desorbed only by contact with hot water at >=60 deg.C in this way, chloroform in city water is removed by a small amt. of the activated carbon by repeating the adsorption and desorption of chloroform.
