Title: Method and ventilator for giving plural respirations which are substantially same
Inventor: DAGURASU EFU DEBURIIZU
IPC: A62B9/02
Filed: 1987-11-04
Abstract: PURPOSE: To uniformize a tidal current amount and to make it accurate so as to deliver the same breath to a patient by calculating a breath delivery period before delivering the breath and repeatedly utilizing it at the time of controlling the delivery of the breath to the patient thereafter. CONSTITUTION: As soon as a flow rate reaches a highest flow rate at the time tP, this ventilator 30 waits for 1/2 of an interval before closing a flow control valve for one stage after the time tP. Thereafter, when the respective full intervals elapse, the flow control valve 42 is closed for one stage, the flow rate is finally reduced to 1/2 of the highest flow rate and a controller 44 waits for 1/2 of the interval before quickly closing the flow control valve 42 so as to end the breath at the time. When the delivery of the breath of one time of one of profiles is completed, the ventilator 30 waits for the time predetermined based on a previously selected breathing rate before delivering another breath.  The succeeding respective breath delivered by the ventilator 30 are defined based on the same highest flow rate, the actual flow rate, the breath delivery period and the profile of inclination utilized for delivering the first breath, and all of them are calculated before delivering the breath.

Title: Photodetector device
Inventor: TAKEKOSHI YOSHITAKA
IPC: H03M1/10
Filed: 1985-12-17
Abstract: PURPOSE:To prevent the malfunction due to noise by dividing variably the quantity of electricity of an electric signal being generated by a signal generating means into two, and supplying these divided quantities of electricity to a pair of input terminals of a comparing means, individually. CONSTITUTION:For the purpose of controlling the offset of a photodetector device, the light from a light source (omitted in the figure) is irradiated to three photodetectors A1, A2, and B simultaneously. Then, currents generated by photodetectors A1 and A2 flow to resistances RL1 and RL2, and the current generated by the photodetector B is divided in accordance with the reciprocal of a resistance value ratio of a variable resistance VR divided by a slide contact (c). After the control of the offset, the device performs the photodetecting operation to output photodetection signals corresponding to quantities of light which photodetectors A1 and A2 receive. That is, a comparator OP outputs signal '1' if the potential at a point (a) is higher than that at a point (b), and the comparator OP outputs signal '0' if the former is lower than the latter. As the result, noise rating quantities in the non-inverted input terminal and the inverted input terminal of the comparator OP are equalized.

Filed: 1992-10-20
Abstract: PURPOSE:To obtain the fiber reinforced plastic free from He leak, excellent in cracking resistance, substantially close to zero in magnetism and light in weight by a method wherein, in a tubular or column-like fiber reinforced plastic integrally made from resin and organic fiber, a roving of the organic fiber is set at a specific angle to the axis of the plastic to be molded. CONSTITUTION:The organic fiber for use in the molding of fiber reinforced plastic is high in strength and elastic modulus and is made from polyethylene, aramid, polyarylate or PBZ polymer and the use of polyethylene is particularly desirable. A roving having the organic fiber wound therearound is set at an angle of + or -40-+ or -80 degrees to the axis of the plastic molding. Preferably, this orientation angle is to be set at + or -45-+ or -75 degrees. If the angle is less than 40 degrees, the plastic is largely expanded to outside and, if the angle exceeds 80 degrees, the thermal stress occurring inside the plastic becomes large, making the plastic liable to cracking.

IPC: B65H19/10
Filed: 1989-10-30
Abstract: PURPOSE:To eliminate the necessity of correcting an error in feeding of paper by an operator so as to make convenient an image forming device by driving a paper feeding means in the reverse direction when an error in feeding of paper detecting means detects the error, so that the device reverts to the condition whereby feeding of paper is possible. CONSTITUTION:In the event that a tension sensor 29 is not turned on even after driving of a paper feeding motor 31 by a predetermined amount, a microprocessor 30 diagnoses it as an error in automatic feeding of paper and then starts to make preparations for rewinding paper. When an error in automatic feeding of paper occurs the microprocessor 30 first turns off the paper feeding motor 31 to stop the motor 31; the microprocessor 30 then drives the paper feeding motor 31 in the direction opposite to that in which paper is fed, so that rewinding of paper is started. Microcapsule paper 13 is thus rewound into a cassette 28 by the paper feeding motor 31, and when an empty sensor 18 is turned off the microprocessor 30 diagnoses it as the finish of rewinding and turns off the paper feeding motor 31.
